Abstract: Disclosed is a component for solid oxide fuel cells that is excellent in both electrical conductivity and chromium poisoning resistance. As a substrate, a ferritic stainless steel having a chemical composition containing, in mass %, Cr: 14.0% to 32.0% and Al: 2.50% to 7.00% is used. Precious metal particles are coated on a surface of the substrate. The precious metal particles have: an average particle size of 1 ?m or more and 10 ?m or less; a coating thickness of 0.5 ?m or more and 10 ?m or less; and a surface coverage of 1.0% or more.

Abstract: A caliper device used together with a brake shoe to retard rotation of a rotor includes a brake arm that is swung relative to a main body by a driving mechanism. The brake arm moves the brake shoe between a brake position and a non-brake position. The caliper device further includes a friction mechanism that increases friction against a swinging movement of the brake arm relative to the main body.

Abstract: The present invention provides a small brake cylinder device that can increase braking force output from a brake output portion that moves along with a rod, while suppressing an increase in the device size. A piston defines a pressure chamber and surrounds the axis of the rod inside a cylinder body, and moves in a linear direction that is parallel to the movement direction of the rod. When pressure fluid is supplied to the pressure chamber, the piston moves in the backward movement direction relative to the cylinder body in resistance to biasing force from a rod biasing spring. Swinging members of a force amplifying mechanism swing due to being biased by the piston moving in the backward movement direction, and moves the rod by biasing it in the forward movement direction. The force amplifying mechanism amplifies the drive force generated by the piston and applies it to the rod.

Abstract: The present invention provides a process for efficiently dephosphorizing, dephosphorizing and decarbonizing, or desulfurizing, dephosphorizing and decarbonizing a hot metal in a converter. The amount of flux to be charged and the amount of bottom-blown gas are adjusted so that the bottom-blowing agitation power and the CaO/SiO.sub.2 ratio subsequent to the treatment become at least 0.1 kW/ton and from 0.7 to 2.5, respectively and the hot metal temperature at the treatment end point becomes from 1,200.degree. to 1,450.degree. C. Furthermore, the operation of the process is controlled so that the sum of a T.Fe concentration and a MnO concentration in the slag subsequent to the treatment becomes from 10 to 35% by weight by adjusting the top-blown oxygen feed rate, the flow rate of bottom-blown gas or the top-blowing lance height.
