Title: Machining method of superconductive thin-film
Inventor: TANAKA SABURO
IPC: C04B41/91
Filed: 1989-03-30
Abstract: PURPOSE:To machine an oxide superconductive thin-film, the characteristics of an oxide superconductor of which are not deteriorated, by forming a metallic layer having low reactivity onto the surface of the oxide superconductive thin- film and then a resist film onto the metallic layer. CONSTITUTION:A metallic layer having low reactivity with an oxide superconductor constituting an oxide superconductive thin-film is formed onto the surface of the thin-film using a photolithographic technique, and a resist film onto the metallic layer. Consequently, since the oxide superconductive thin-film is not brought into contact directly with a resist, a developer, etc., and also receives no ion bombardment, characteristics thereof are not deteriorated. A metal having low resistivity with the oxide superconductor such as Ag, Al, In, etc., can be used as a metallic layer material. Accordingly, the oxide superconductive thin-film can be machined to various superconducting devices without lowering the superconductive characteristics of the thin-film.

Title: Bearing structure of crank shaft
Inventor: SHIBATA TAKUJI
IPC: F16C9/02
Filed: 1998-03-26
Abstract: PROBLEM TO BE SOLVED: To provide a bearing structure for a crank shaft with high durability which can keep strength of a crank bearing cap to be attached to a lower surface of a cylinder block. SOLUTION: In this bearing structure, companion surfaces 4b of crank bearing caps 4 each formed with a central arcuate recession to compose a bearing part 4a are tapered by angle θ to form an inverted chevron shape. The crank bearing cap 4 is fastened to a cylinder block 2 by means of a bolt 5. The crank bearing caps 4 are brought into close contact with each other with deformation. Compression stress is generated on a lower portion of the bearing portion 4a, that is, a bridge portion 6. A tensile stress at the time of fastening and a tensile stress generated on the bridge portion 6 under engine operation are cancelled by the compression stress. The tensile stress is reduced compared to the conventional cap 4. It is thus possible to reduce metal fatigue of the cap 4.
