    摘要： A method for producing suspension parts via preforming the workpiece by roll forming. The sectional area and length of the workpiece are calculated. In the former step, more than one orthogonal cross-section is acquired from the suspension part of aluminum alloy, and the sectional area is converted into the area of a circle. An imaginary area is calculated by adding to the converted area an adequate amount of flash. In the latter step, a circular truncated cone is defined from two adjacent imaginary circles and the length of the imaginary center line between the two adjacent imaginary circles. A solid of revolution is defined by connecting these circular truncated cones, and the volume of the suspension part of aluminum alloy is substituted by the volume of the solid of revolution. The value obtained by dividing the sectional area of the workpiece by the volume is regarded as the-length of the workpiece.

    摘要： A sander (1) has a motor (3) with a motor shaft (4) mounted in a bearing box (11) via an eccentric ball bearing (10). Coupled to the bearing box (11) is a pad (12) having a bulged square shape in a horizontal cross section. The sander (1) further includes a skirt (6) with an opening (6a) on which a synthetic (polyurethane rubber) brake ring (17) is mounted. The brake ring (17) comprises an outer peripheral portion (18) and a plurality of contact portions (19) disposed at regular intervals around the outer peripheral portion (18). Each contact portion (19) is bulged toward the center of the brake ring (17) with both ends connected to the outer peripheral portion (18). Also, the contact portions (19) are elastic so as to deform in the radial direction. The contact portions (19) together form a through-hole (21) which is slightly smaller than the bearing box (11) for receiving the bearing box.

A bending die used in the apparatus for manufacturing the automotive suspension arm to bend a rod-like raw material and produce a bent material includes a lower bending die including a mounting portion for mounting thereon the rod-like raw material and an upper bending die including a pressing portion for vertically pressing the rod-like raw material mounted on the lower bending die. The mounting portion and the pressing portion include a lower die contact portion and an upper die contact portion each formed into a shape along the bent shape of the bent material to come in contact with the bent material. The lower die contact portion includes, in the middle portion thereof, a groove portion formed to have a size which allows a moving means to grip the bent material in non-contact relation with the bent material.

    摘要： According to an aspect of the present invention, a piston ring for use in internal combustion engines is provided that is made of matensite-based stainless steel material containing C of not less than 0.4 and not more than 0.8 weight percent, Si of not less than 0.16 and not more than 0.4 weight percent, Mn of not less than 0.1 and not more than 0.4 weight percent, and Cr of not less than 2.0 and not more than 11.0 weight percent, where the steel material of the piston ring has mainly chromium carbide precipitated in the base texture thereof. The steel material of the first compression ring then has a nitriding layer formed thereon. According to another aspect of the present invention, a combination of compression rings, including a first compression ring 1 and a second compression ring 2, for use in internal combustion engines, is provided. The first compression ring 1 is made of martensite-based stainless steel material containing C of not less than 0.16 and not more than 1.4 weight percent, and Cr of not less than 12 and not more than 23.0 weight percent, where the steel material of the first compression ring 1 has mainly chromium carbide precipitated in the base texture thereof. The steel material of the first compression ring 1 then has a nitriding layer 11 of hardness of not less than Hv1050 formed thereon. The second compression ring 2 is made of the same steel material as the piston ring first described above, with mainly chromium carbide likewise precipitated in the base texture thereof The steel material of the second compression ring 2 then has a nitriding layer 22 of hardness of less than Hv1050 formed thereon. With the arrangement above, according to the present invention, piston rings have an advantage of excellent bending workability during the ring forming process. Likewise, a combination of first and second compression rings 1 and 2, has an advantage of reducing the total manufacturing cost of the combination of the compression rings, and an excellent abrasion resistance, with a second compression ring exhibiting excellent cold workability during the ring forming process.
