摘要： Provided is a tape-shaped contact member including a tape-shaped contact material. At least one wire-shaped brazing material is bonded to the tape-shaped contact material, at least one projection including the brazing material and protruding from a surface of the contact material is formed in a cross-sectional shape, a diffusion region containing a metal component forming the brazing material is formed along an interface with the brazing material inside the contact material, and the diffusion region has a thickness of 2 μm or more and 10 μm or less. A chip-shaped contact component can be obtained by cutting the tape-shaped contact member to an arbitrary length. The present contact component is useful as a constituent member for a switching electrical contact, and capable of adapting to height reduction of the electrical contact. The present invention can also contribute to reduction of occurrence of poor bonding.

摘要： The present invention provides an artifactless superelastic alloy including a Au—Cu—Al alloy, the superelastic alloy containing Cu in an amount of 20 atom % or more and 40 atom % or less, Al in an amount of 15 atom % or more and 25 atom % or less, and Au as a balance, the superelastic alloy having a bulk magnetic susceptibility of −24 ppm or more and 6 ppm or less. The Ni-free superelastic alloy of the present invention is capable of exhibiting superelasticity in a normal temperature range, and hardly generated artifacts in a magnetic field environment. The alloy can be produced by setting a casting time in a melting and casting step to a fixed time, and hot-pressing an alloy after casting to make material structures homogeneous.

摘要： The present invention relates to a catalyst for solid polymer fuel cells in which catalyst particles including platinum and a transition metal M are supported on a carbon powder carrier. The catalyst of the present invention is a catalyst for solid polymer fuel cells in which a molar ratio (Pt/M) of platinum to the transition metal M that form catalyst particles is 2.5 or more, and a ratio (SCOMSA/SBET) of a platinum specific surface area (SCOMSA) measured by a CO adsorption method to a catalyst specific surface area (SBET) measured by a BET method is 0.26 or more and 0.32 or less. The catalyst can be produced by preparing an alloy catalyst, then washing the alloy catalyst with a platinum compound solution, and additionally supplying platinum to the surfaces of catalyst particles.

The sealing member includes a compressed product of a metal powder including gold having a purity of 99.9% by mass or more and a lid-like metal film including a bulk-like metal including gold and having a thickness of not less than 0.01 μm and not more than 5 μm. The sealing material includes an outer periphery-side densified region in contact with an underlying metal film and a center-side porous region in contact with the through-hole. The shape of pores in the densified region is specified, and the horizontal length (l) of a pore in the radial direction at any cross-section of the densified region and the width (W) of the densified region satisfy the relationship of l≤0.1W.
