A rocking operation type electric component is presented that includes: an operation knob that has a bottomed case-shaped configuration and is rockably held; a signal generating unit that includes a movable element pressed and driven by the operation knob and generates a different electric signal in response to a position change of the movable element; and a case on which a mounting frame for pivotally supporting the operation knob is protrusively provided formed and in which the signal generating unit is received. A pair of rotation shafts which face each other are protrusively formed on inner wall portions of the operation knob, respectively. Through-holes are respectively formed in a pair of wall portions of the mounting frame which face each other. The rotation shafts are fitted into the through-holes from the outside of the mounting frame to be rotatably supported by the mounting frame.

Provided is an electronic device with a touch panel, wherein the device can reliably inform an operator of the completion of input, etc., and has a reduced thickness. The electronic device (1) with a touch panel is provided with a display panel (11), the touch panel (12), a vibratory element (20), and vibration transmission members (15, 16). The touch panel (12) is arranged above the display panel (11). The vibratory element (20) is arranged on the side of the display panel (11). The vibration transmission members (15, 16) transmit vibration of the vibratory element (20) to the touch panel (12). The vibratory element is arranged so that the vibration direction of a vibration plate (22) is parallel with the direction of the normal line of the display panel (11).

The present invention provides a folding screen device. In a folding screen device which is pulled in the lateral direction, the limit of the widthwise dimension of the screen device in the opening and closing direction of the screen is eliminated. A plurality of screen units 10 in which movable vertical frame members 13, 14 are attached to both ends of a screen 12 which is expandable in an accordion manner, and the vertical frame members are adapted to be slidable along a lateral frame member 3 of an opening 2 of the building. The screen units include screen guides 20A, 20B that move out and into the interior of the vertical frame member 13 through the upper end and the lower end thereof in a bent state, are led along the upper end and the lower end of the screen in an extended state, and a parallel movement mechanism for causing the vertical frame members 13, 14 to move in parallel during the opening and closing operation of the screen.; The screen units 10 can be arranged in parallel in an opening 2 of the building by connecting the adjacent vertical frame members of the plurality of screen units 10.

The invention belongs to the technical field of compressors, and specifically discloses an air valve assembly, which includes an exhaust valve plate, a valve plate and a limiting plate. Installed in conjunction with the groove, the limit plate presses the exhaust valve plate into the groove, the tongue of the exhaust valve plate covers the exhaust port to form an opening and closing valve, and the root of the exhaust valve plate is provided with a grid pattern The grid-like pattern structure is composed of several grid bars arranged at intervals. One or more grid bars of the grid-like pattern structure are provided with a deformation structure. Flatten and stretch out across its width. The invention also discloses a compressor using the above air valve assembly. The invention has simple structure and low cost, and can well solve the problem of powder valve plate wear caused by the sloshing of the exhaust valve plate, which eventually leads to misalignment and poor sealing between the tongue of the exhaust valve plate and the exhaust hole of the valve plate, and severe internal combustion of the compressor. The problem of leakage and failure.

The invention discloses a single body rotating door with a wide passageway. The door comprises a fixed arc wall and a moving arc wall which are arranged oppositely right and left and form a longitudinal passageway, and a folding door wing which is used for forming a fixed wide passageway and is hinged with a central shaft, wherein the moving arc wall is enclosed by at least two arc wall moving bodies; and the at least two arc wall moving bodies can respectively rotate around the central shaft towards inner and outer sides to enclose the fixed arc wall. The single body rotating door can switchbetween functions of the common rotating door and the fixed wide passageway according to the actual requirement; and when the split arc wall moving bodies enclose the inner and outer sides of the fixed arc wall and are matched with the rotation of the folding door wing, the fixed wide passageway with the maximum width is formed on one side of the rotating door, and the requirement of large objects during transportation is met.

The invention discloses an SOP8 package lead frame of a high-power LED driving chip. The SOP8 package lead frame comprises a pin, side connection ribs, a first island and a second island, the pin and the two side connection ribs together support the first island and the second island, the width of the first island is larger than the standard width of an SOP8 package island, and the width of the second island is smaller than the standard width of the SOP8 package island. The size of the largest MOSFET chip borne by the first island is increased, and the SOP8 lead frame is suitable for packaging a 3 W-9 W built-in isolation type LED driving chip or a 12 W-24 W built-in isolation type LED driving chip and is wide in application range. The bearing area of the first island is correspondingly increased, and therefore the heat dissipation performance is good. No special requirements for the MOSFET chip exist, and therefore the cost is low; only one pin is needed, and therefore expandability is good. The SOP8 package lead frame can be widely applied to the field of semiconductor components.
