    摘要： A valve lifter of a valve mechanism for an internal combustion engine is provided with a crown-shaped valve lifter body which has a center plate with a recess. A fixing projection is integrally formed with the center plate and is formed along a side wall which defines the recess. An inner shim of a disc shape has a plurality of grooves to which the fixing projection is filled by caulking the fixing projection for fixedly connecting the inner shim with the valve lifter body. Therefore, the inner shim is easily and securely assembled in the recess of the valve lifter body so as not to generate the looseness between the inner shim and the valve lifter body while the assemble performance is improved.

    摘要翻译： 用于内燃机的阀机构的气门挺杆设置有具有凹部的中心板的冠形气门挺杆体。 固定突起与中心板一体地形成，并且沿着限定凹部的侧壁形成。 盘形的内侧垫片具有多个槽，通过铆接固定突起来固定固定突起，固定突起用于将内垫片与气门挺杆体固定连接。 因此，内部垫片容易且牢固地组装在气门挺杆体的凹部中，以便在组装性能提高的同时不会在内垫片和气门挺杆体之间产生松动。

    摘要： A method of producing a valve lifter to be used in a valve operating mechanism of an automotive vehicle. The valve lifter includes a skirt section, a crown section formed one end of the skirt section so that a cam of a camshaft is slidably contactable with the crown section, and a contacting section formed at an inside surface of the crown section and contactable with a valve stem of an engine valve. The production method comprises the following steps in the sequence set forth: (a) cold-forging a base material to form a valve lifter-shaped base material; (b) cold-pressing the base material to shape the valve lifter-shaped base material; (c) grinding an outer surface of the valve lifter-shaped base material to trim an outer shape of the valve-lifter-shaped base material; (d) totally machining the outer surface and an inner surface of the valve-shaped base material to adjust dimensions of parts of the valve lifter-shaped base material; (e) heat-treating only a part of the valve lifter-shaped base material, corresponding to the contacting section, to increase a hardness of the contacting section; and (f) grinding the contacting section to finish the contacting section.

    摘要： A method of forging a raw material for sintering and forging. The method comprises the steps of: (a) compacting metallic powder containing iron as a main component and graphite to obtain a compact having a predetermined density; (b) sintering the compact at a temperature ranging from 700 to 1000° C. to form a sintered compact having a texture in which graphite is retained at grain boundary of metal powder; (c) compressing the sintered compact from two directions to obtain a compressed sintered compact; and (d) extruding the compressed sintered compact upon pressing the compressed sintered compact from the two directions in a manner that a pressure in one of the two directions is reduced relative to a pressure in the other of the two directions to accomplish extrusion forging.

    摘要： An improved adhesive sheet can exhibit an excellent anti-blister characteristic without susceptible to the property of the base material. The adhesive sheet includes a base material that is formed from a base material film and a thin film laminated onto the base material film, an adhesive layer and a release sheet. The adhesive layer contains an adhesive component and a curing component as its main composition. The curing component is of the type that is to be cured by irradiation with radiation. As for such radiation-curing type component, materials containing acrylic-based monomer or oligomer can be used. The adhesive layer has a storage modulus (dynamic modulus) in which a ratio of storage modulus G2′/G1′ of the adhesive layer lies within the range of 1.2 to 50, wherein G1′ is a storage modulus of the adhesive layer before curing at a temperature of 25° C. and at a frequency of 1 Hz, and G2′ is a storage modulus of the adhesive layer after curing at a temperature of 25° C. and at a frequency of 1 Hz.
