An ice-making device installed in an ice-making chamber with a door, comprising an ice-making pan, a drive part, a holding body, and a holding part. The ice-making pan further comprises a first shaft part installed in the direction of the door and a second shaft part installed in the direction opposite to the door, and water to be frozen is supplied thereinto. The drive part further comprises a rotating shaft detachably connected to the second shaft part of the ice-making pan, and is installed at a position opposite to the door of the ice-making chamber. The drive part separates an ice from the ice-making pan by providing a force to the ice when the ice is generated by the freezing of the supplied water. The holding body supports the first shaft part and the second shaft part of the ice-making pan, and is formed integrally with the ice-making pan to form an ice-making pan unit. The holding part supports at least either of the first shaft part and the second shaft part by holding in association with the holding body.

An adhesive tape which has an adhesive layer on at least one face of a foam substrate, wherein the 25% compressive strength of the foam substrate is 250 kPa or more, the average bubble size in the flow direction and width direction in the foam substrate is 150 mum or less, and the ratio of the average bubble size in the flow direction / the average bubble size in the thickness direction and the ratio of the average bubble size in the width direction / the average bubble size in the thickness direction are 5 or less. Thus, even if the tape is narrow, excellent conformability to the shape of an adherend, excellent shock resistance, and favorable rework properties can be achieved with this tape.

The invention relates to a square box. The square box is formed by the following steps of: taking out a piece of large square paper, and leading four oblique lines 1 which are intersected with each other from four corners of the paper, wherein the middle square of the paper is the box bottom; leading segments 2 which are perpendicular to the oblique lines 1 from the four oblique lines 1 to the intersection of the paper sides; leading an angular bisector 3 from the intersection of two oblique lines 1 to the nearest paper side; taking out a piece of small square paper, wherein the side length of the small square paper is the length between two parallel segments 2; placing the small square paper below the large square paper, wherein the four sides of the small square paper are overlapped with four segments 2 of the large square paper, and the four angular bisectors 3 of the large square paper are lengthened to four paper corners of the small square paper; folding the four corners of the large square paper according to the four segments 2; folding the overlapped large and small square paper according to the folding line, and inserting the sharp corner folding parts in the interlayers outside the box counterclockwise. The small square paper overcomes the defect of large square paper so that the area of the pressed part inserted outside the box is enlarged to avoid separation and the square box is firmer, stiffer, smoother and harder.

An electrical connector comprises a male connector component supporting connecting terminals, which are electrically connected to to-be-connecting terminals of a female connector element, and a cover element attached to the male connector component to the connecting terminals. The male connector component includes a peripheral wall, which forms a cavity for a ferrite member and which includes flexible latches to restrain movement of the ferrite member. The cover element includes an outer peripheral wall adapted for fitting the peripheral wall of the male connector component. The cover element also includes a latching part disposed on an outer surface of the outer peripheral wall and expanding outward. The latching part engages with a recess formed in an opening of the female connector component when the cover element is fitted into the opening together with the male connector component.

A piezoelectric layer with an individual electrode and a contact point formed thereon, and an FPC having a substrate on which a wiring is formed are in this order arranged on a surface of a channel unit having a pressure chamber. A first through hole is formed in an area, of the substrate, overlapping in a plan view with the contact point, and a second through hole is formed in another area, of the substrate, not overlapping in a plan view with the pressure chamber. An electroconductive material is filled in the first through hole, and a fixing material is filled in the second through hole. Accordingly, it is possible to electrically connect the individual electrode and the wiring of the FPC, and to mechanically connect the piezoelectric layer and the substrate of the FPC.

A male connector component 12 supports a pair of connecting terminals 11 electrically connected to a pair of to-be-connected terminals 4 supported by a female connector component 2, and is fitted to an opening 3 formed in the female connector component 2. A cover element 13 is fitted to the male connector component 12 in such a way as to sandwich the connecting terminals 11 while covering the upper opening of the male connector component 12. The cover element 13 has a convex part that is engaged with a concave part 5 formed in the opening 3 when it is fitted to the opening 3 together with the male connector component 12.

The invention discloses a rounded zipper tooth. The rounded zipper tooth comprises a zipper tooth body. The zipper tooth body is a semicircular columnar body. One end of one engaging surface of the zipper tooth body and one end of the other engaging surface of the zipper tooth body are recessed into the zipper tooth body to form an engaging portion and engaging concave portions, positioning portions are arranged on the engaging concave portions, and positioning grooves are formed in the engaging portion. The rounded zipper tooth is special in structural design, and when zipper teeth are engaged, the engaged zipper teeth are round. Compared with the prior art, the rounded zipper teeth are in dual engaging and locking during mutual engaging, the engaging portion of one zipper tooth is engaged with the engaging concave portions of the other zipper tooth, the positioning portions of one zipper tooth are clamped and locked with the positioning grooves of the other zipper tooth, the zipper teeth are engaged and locked in two dimensional directions, and engaging of the interacting zipper teeth is firmer; even when the zipper teeth are torn by large external force from the left-and-right direction, the engaged zipper teeth are not prone to disengage.

A pilot-controlled electromagnetic valve system has an electromagnetic valve block mounted on the top of a manifold block. A bearing surface is formed on the top of the electromagnetic valve block at a position adjacent to a screw accommodating recess formed on a joint surface at a side of the electromagnetic valve block. A washer engagement groove is formed at the bearing surface. An inwardly sloped washer having an engagement portion at the inner side thereof is fitted on a screw. The engagement portion is engaged with a side wall of the washer engagement groove. Thus, the electromagnetic valve block is surely secured to the manifold block with the screw even if the electromagnetic valve block is one at an end of a series of electromagnetic valve blocks constituting a valve manifold, or provided singly.

The invention relates to the technical field of photography and video shooting equipment, particularly to a button mechanism of a tripod and the tripod. The button mechanism of the tripod comprises angle clamping structures and button structures, and further comprises supporting structures, wherein the angle clamping structures are fixedly arranged on a body of the tripod; the button structures comprise buttons rotatably arranged on foot shaft sleeves of the tripod through first shafts; the buttons are provided with combination parts applicable to combination with clamps of the angle clamping structures; the combination parts and the clamps are combined to lock the opening angle of supporting feet of the tripod; when the combination parts and the clamps are combined, the supporting structures are propped against the buttons; and included angles exist between the extension lines of the connecting lines from supporting parts of the supporting structures to the combination parts and the extension lines of the ends, facing the angle clamping structures, of the supporting feet. According to the button mechanism of the tripod and the tripod provided by the invention, supporting stability of the supporting feet of the tripod is strengthened, cost of the angle clamping structures is reduced, product structure is further simplified, and market competitiveness of products is improved.
