The purpose of the present invention is to provide: a steel material for API 5L X60 to X70 grade highly-deformable line pipes that exhibits excellent anti-HIC characteristics in a wet hydrogen sulfide environment having a pH of 5 or more, and that has a low yield ratio even after undergoing a coating process at 300C or less; a method for manufacturing the steel material; and a welded steel pipe. The steel material for highly-deformable line pipes that exhibits strain aging characteristics and anti-HIC characteristics has: a specific composition; has a metal structure primarily comprising ferrite and bainite, the area fraction of the ferrite and bainite totaling at least 90%, and the difference in hardness between the ferrite and the bainite being at least 70 in terms of Vickers hardness; and a uniform elongation of at least 9% and a yield ratio of not more than 90% with regard to pre- and post-strain aging treatment at 300C or less.


A method comprising steps of: forming an integral brake caliper body and support bracket that comprises a caliper body (200) and a support bracket (300); and separating the caliper body from the support bracket. The caliper body (200) and the support bracket (300) can be formed via casting process. The present teachings further provides a core (10) including: a piston projection (14) for forming a piston bore (214) in the caliper body (200), and a base (12) for forming a gap (312) between arms (313A, B) of the support bracket (300), wherein the core is part of a tool for forming the integral brake caliper body and support bracket.


Provided is a brake block including a friction material whose friction coefficient is decreased to the same level as in a cast iron-based friction material while ensuring braking properties under dry and wet conditions and a method for producing the same. The brake block I includes a friction material 3 including a scale-like graphite and a granular graphite in an amount of 20 to 30% by volume in total. The brake block I is produced by a production method including: a preforming step of subjecting a frictional material composition including a scale-like graphite and a granular graphite in an amount of 20 to 30% by volume in total to pressure forming, thereby obtaining a preformed body, and a heat compression forming step of putting the preformed body into a thermoforming mold, and overlaying a back plate thereon, followed by performing heat compression forming, thereby obtaining a brake block I having a desired shape.

A linear actuation assembly comprising: (a) a differential assembly and (b) a pair of linear actuators in communication with the differential assembly; wherein the pair of linear actuators are movable along an axis so that during movement of each of the pair of linear actuators a pair of brake shoes are moved to create a brake force or moved to release a brake force, and wherein the differential assembly distributes power equally to each of the pair of linear actuators until resistance of one of the brake shoes increases then the differential assembly ceases to provide power to the brake shoe with increased resistance and distributes the power from the brake shoe with increased resistance to a brake shoe of lower resistance until a brake force is created.


A mold (1) for a brake pad friction material, said mold being equipped with a mold member (2) that fits into a mold frame (4) into which a powder material (5) of the brake pad friction material is injected. A pressing surface (3), which forms the region of the surface of the mold member (2) making contact with the powder material (5) injected into the mold frame (4), has a concave shape such that the pressing surface (3) gradually slopes downward from the ends of the pressing surface toward the center part thereof.

In an opposed-piston disc brake caliper, a pair of reinforcement bridge portions (20a, 20b, 21a, 21b), which are inclined relative to an axial direction, are provided on outside of a rotor in a radial direction of the rotor so as to define corner opening portions (34a-d) in an opening portion which is defined by an inner body portion (2a), an outer body portion (3a), and an entry-side connection portion (4a) and an exit-side connection portion (5a) connecting the inner body portion and the outer body portion. A torque receiving portion of one of the entry-side torque receiving portion and the exit-side torque receiving portion (25a, 25b, 26a, 26b) is exposed toward an outside in the radial direction via the corner opening portions.
