Abstract: An inspection device 1 is provided to inspect a headrest return prevention mechanism 50 that prevents return of a headrest at a position supporting the head of a seated person by moving forward at a rear collision. The headrest return prevention mechanism 50 is provided with a bracket 52 and an engagement piece 51 which can return to a normal position again after being displaced from the normal position to a fixed position. The inspection device 1 comprises a base 11, a clamp mechanism 12 that fixes the bracket 52 to the base 11, a load applying mechanism 13 that applies a load to the engagement piece 51 so as to displace it from the normal position to the fixed position, a displacement sensor 14 that measures the fixed position when the engagement piece 51 is displaced from the normal position to the fixed position, and a computer 15 that determines whether the engagement piece 51 has been displaced to a predetermined fixed position or not based on the fixed position measured by the displacement sensor 14.

Abstract: A material for a nuclear fusion reactor of the present invention contains intermetallic compounds of beryllium with Ti, V, Zr, Nb, Ta, Mo, W or Y. The beryllium intermetallic compounds are mixed with another metal or intermetallic compound. The material is preferably applied to blankets and facing members which are exposed to neutrons and heat generated by plasma of the nuclear fusion reactor.

Abstract: The present invention provides a method of producing a bonded body of a beryllium member and a copper or copper alloy member, in which the bonding strength and thermal cycle resistance property are further increased. When the beryllium member and the copper or copper alloy member are bonded to each other, a thin layer of titanium, chromium, molybdenum, or silicon is formed as a diffusion inhibition layer on the surface of the beryllium; a copper layer is formed as a bonding layer on the surface of the diffusion inhibition layer; a thin layer of aluminum or zinc is formed as a bonding promotion layer on the surface of the bonding layer; and the beryllium member and the copper or copper alloy member are diffusion bonded to each other with the intermediate layer formation side being the bonding surface.

Abstract: A mold composed of bonded water-insoluble particles and having a molding layer and a support layer. The molding layer includes first water insoluble particles, having an average size of 0.2 -1.0 mm bonded to form a layer having a thickness 1-20 times the average size of the first particles. The support layer positioned on the inner surface of the molding layer, on which the fiber bodies are not formed, includes second water-insoluble particles, having an average size of 1.0-10.0 mm, bonded to form a layer having a thickness of at least the average size of the second particles. The pulp mold has advantages in that it hardly suffers from clogging, it produces fiber bodies each having a smooth surface, it is free from damage caused by repeated use, and it produces fiber bodies in a short period of time.

Abstract: A pulp molding die for molding shaped articles from fiber pulp is disclosed. The die has a porous molding layer having a porosity of at least 5% and an average pore diameter in a range of 60 to 1000 .mu.m, the porous molding layer having a molding surface shaped to the configuration of the article to be molded; and a porous support layer disposed adjacent the porous molding layer on the opposite side thereof from the molding surface, the porous support layer having a porosity of at least 20% and an average pore diameter in a range of 0.6 to 10 mm, the average pore diameter being larger than that of the porous molding layer. The porous molding layer and/or the porous support layer have a pore structure for holding water.
