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.

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.

Providing a bumper absorbing large amount of impact energy with respect to both a light collision and a heavy collision, and preventing the reinforcement beam from bending and protruding backward at a portion where an obstacle collides and from displacing backward in this protruding state. Provided is a bumper for vehicles including a reinforcement beam made of metal and a pair of support members having a hollow cross section, protruding from a vehicle frame, and supporting the reinforcement beam therebetween. 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.

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 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.

Disclosed is a sliding bearing consisting of a pair of semi-cylindrical bearings for supporting a crankshaft or a crank pin in an internal combustion engine. The sliding bearing is incorporated in a split-type bearing housing. One of the semi-cylindrical bearings being incorporated in at least one of the pair of housing halves, which one housing half has a relatively higher stiffness, is provided with a number of circumferential grooves on an inner surface of the semi-cylindrical bearing so as to extend circumferentially along the inner surface of the semi-cylindrical bearing. The circumferential grooves existing at least one circumferential end region of the inner surface of the semi-cylindrical bearing have a depth of not less than 10 μm, the circumferential end region including a circumferential bearing end face orientating a direction opposite to the rotation direction of the shaft or pin.

The laminated sheet of this invention is a sheet including expanded porous polytetrafluoroethylene films laminated by thermal compression bonding, wherein the sheet has a specific surface area of 9.0 m2 / g or larger and a density of from 0.4 g / cm3 to lower than 0.75 g / cm3, thereby making it possible to improve both the creep resistance and the adhesiveness between the films of the expanded porous PTFE film-laminated sheet.
