In a method of manufacturing a stator core of an electric rotating machine, a cylindrical laminated core is formed by thinning a side portion of a steel plate with magnetic pole teeth and helically winding the steel sheet, and the stator core is manufactured by performing ironing for the laminated core. This laminated core has steel sheets aligned along the axial direction thereof, and the sheets have respective thinned outer end portions spaced apart from one another on the outer side of the laminated core. In the ironing, the thinned outer end portions of the steel sheets are brought into contact with one another in a forming apparatus, and an ironing load is given to the thinned outer end portions to shorten lengths of the thinned outer end portions in the radial direction of the laminated core at a predetermined value.

A pellicle which has a mask adhesive layer that can be plastic-deformed readily particularly at a temperature at which exposure to light is carried out, rarely provides a residue of an adhesive agent upon the removal of the mask adhesive layer from a mask and has good handling properties, and which can prevent the position gap of a pattern. The pellicle comprises a pellicle frame, a pellicle membrane and a mask adhesive layer containing a mask adhesive agent. The mask adhesive agent comprises 100 parts by mass of a thermoplastic elastomer (A) having a tan δ peak temperature of −20 to 30 DEG C and 20 to 150 parts by mass of an adhesiveness-imparting resin (B).

The aim of the invention is to create a receptacle (4) which is used for evaporating condensed liquid on a small coolant compressor, allows the heat generated by the small coolant compressor to be utilized in an optimal way, and is easy and inexpensive to produce and mount on the compressor housing. Said aim is achieved by embodying the receptacle (4) as a plastic part that is deep-drawn in a receiving device (6) directly on the compressor housing. The plastic part perfectly matches the shape of the receiving device (6) such that the air gap that is usually formed between the compressor housing and the receptacle (4) can be eliminated altogether or reduced to a minimum. A holding element (2) that is arranged on the outer circumference of the cover part (1) ensures optimum support for the receptacle (4), thus dispensing with the need for expensive anti-corrosive measures while the evaporator power and the coefficient of performance (COP) of the small coolant compressor are optimized.

The copper alloy wire comprises, by weight, 20 to 40% of manganese, 20 to 30% of zinc, or 20 to 30% of zinc and manganese, and the balance copper. According to the copper alloy wire, relatively cheap manganese and / or zinc is added into copper base material according to the weight ratio so as to improve copper wire physico-chemical properties relating to wire bonding technology, wire melting point is reduced, wire oxidation resistance and corrosion resistance are improved, wire thermal softening degree at a working temperature is increased, and wire material cost is reduced; and in addition, oxidation resistance of the copper alloy wire is increased, so that reducing protective gas is not necessary in wire bonding processes, using of nitrogen is enough, and accidents are avoided.

Disclosed herein is a prismatic battery having an electrode assembly mounted in a prismatic battery case, wherein an electrolyte injection hole formed in a base plate mounted to an open upper end of the battery case is constructed such that an inside upper end of the electrolyte injection hole is formed in a downward taper (incline) structure, and a metal ball is forcibly inserted into the electrolyte injection hole such that the metal ball is plastically deformed to seal the electrolyte injection hole. The prismatic battery according to the present invention provides high coupling force between the metal ball and the electrolyte injection hole due to the plastic deformation and forced insertion of the metal ball and high sealability of the electrolyte injection hole. Also, the formation of a groove at the upper end of the forcibly inserted metal ball and the generation of cracks at the interface between the metal ball and the inside surface of the electrolyte injection hole are effectively prevented. Consequently, the present invention has the effect of accomplishing high electrolyte sealability.

The invention relates to an alternating current electromagnetic valve comprising a movable iron core, a stationary iron core and an electromagnetic coil. The movable iron core is arranged in a magnetic sleeve and slides under the action of magnetic force to open and close a valve pathway; the stationary iron core attracts the movable iron core and blocks the movable iron core to slide; the electromagnetic coil is arranged outside the magnetic sleeve; the end of the stationary iron core facing to the movable iron core is provided with an annular groove; and a shading ring is arranged in the annular groove. The alternating current electromagnetic valve is characterized in that the shading ring is made of soft aluminum material, and the annular groove is in a ladder-shaped structure which is gradually widened from an opening to the inside in the direction of the cross section. The shading ring made of the soft aluminum material is arranged in the groove after being deformed by external force in the installation process, therefore, the structure ensures that the shading ring can not easily fall off, is suitable for normally working in a vibration environment and ensures the reliability of a product.

A quenched region is provide over a portion including a middle of the reinforcement beam. Unquenched portions are provided on the pair of connecting portions or a pair of adjacent portions inside the pair of connecting portions.

A scaffolding pipe of a structural scaffolding system extends from a first axial pipe end to an opposing second axial pipe end. A receiving portion is provided on the first axial pipe end and an insertion portion is provided on the second axial pipe end. The insertion portion has a reduced cross-section compared with the receiving portion and terminates with a radial shoulder which forms a support face. The receiving portion inner diameter is greater than the insertion portion outer diameter. The receiving portion at the first axial pipe end has one positioning groove which is interrupted or continuous in a peripheral direction which reduces the inner diameter of the receiving portion and which defines the minimum inner diameter of the receiving portion. A pipe wall of the scaffolding pipe has at the first axial pipe end a maximum wall thickness greater than the otherwise smaller wall thickness.

A webbing take-up device reduced in cost by a reduction in size of a pre- tensioner and a lock device and a reduction in number of parts, wherein a plurality of projected parts (126) are formed on the inner peripheral part o f a bearing main body (124) pivotally supporting a clutch part (106) and are in linear contact with the outer peripheral part of the clutch part (106) so th at the bearing main body (124) pivotally supports the clutch part (106) indirectly through the projected parts (126), whereby, because the projected parts (126) are in linear contact with the clutch part (106), a contact area becomes extremely small and the projected parts (126) are easily deformed plastically by a frictional resistance between the projected parts (126) and the clutch part (106), and thus a resistance to prevent the clutch part (106) from rotating is reduced enough to supply a gas pressure efficiently for the rotation of a take-up shaft (20) and, as a result, those members which form the pre-tensioner (14) such as a gas generator (158) can be reduced in size and cost.
