Title: Production of melamine resin/metal decorative panel
Inventor: SUZUKI SHOICHI
IPC: B32B15/08
Filed: 1990-06-28
Abstract: PURPOSE:To suppress the flow of a phenol resin by a method wherein a phenol resin impregnated fibrous base material is superposed on a metal plate and a melamine resin impregnated fibrous base material is further superposed thereon to be pressed under heating and a process lowering predetermined molding pressure by a definite ratio or less thereof during the melting of a phenol resin to again restore the predetermined pressure is repeated twice or more. CONSTITUTION:A process lowering predetermined molding pressure to the range of 70-0% thereof to again restore the predetermined molding pressure is repeated twice or more during the melting of a phenol resin. The phenol resin becomes a molten state during the period of t1-t2 among the total molding time, that is, within the temp. range of T1-T2 but, during this period, molding pressure P1 is lowered to P2 two or more times. A molding condition can be achieved while the flow of the phenol resin is suppressed by the change of this molding pressure condition. Therefore, the penetration of the phenol resin into a melamine resin layer due to the excessive flow of the phenol resin is not generated.

Title: Magnetic bearing device
Inventor: URANO TOMOAKI
IPC: F16C32/04
Filed: 1987-07-09
Abstract: PURPOSE:To prevent separation of lubricant film by coating a soft metal lubri cant film with molybdenum disulfide. CONSTITUTION:Upon interruption of power supply to an electromagnet, a rotor shaft 10 contacts with protection dry bearings 21, 22 and supported rotatably. High speed rotation of the rotor shaft is transmitted abruptly to the protection dry bearings 21, 22 to cause rotation of inner races 26 thereof with same rotary speed. Consequently, balls 24 make rolling contact with the ball side surface 26a of the inner race 26 and the ball side surface 27a of an outer race 27, but since soft metal lubricant films 31 are formed on the surfaces thereof and the uppermost surface layer 32 is coated with molybdenum disulfide, smooth lubrica tion can be achieved without requiring lubricant. As a result, separation of lubricant film due to reactive gas can be prevented and deterioration of durabil ity can be prevented.

Title: Method for reclaiming alloy containing rare earth element
Inventor: FUJINE MICHIHIKO
IPC: C22B7/00
Filed: 1988-07-08
Abstract: PURPOSE:To reclaim large amounts of scraps, etc., into the original composition at a low cost by applying hydrogen reduction to the compound of an alloy containing rare earth element to reduce a mother alloy and then reducing the compound of the rare earth element by means of alkaline (earth) metal. CONSTITUTION:The compound of an alloy containing mother metal and rare earth element, such as scrap, is subjected to oxidizing decarburizing treatment. Subsequently, hydrogen reduction is first carried out to reduce the compound of the mother metal, such as Co, Fe, and Cu. Successively, the reduction of the compound of the rare earth element is carried out by using a powder of alkali metal or alkaline earth metal, such as Ca. Since the generation of large quantity of heat can be prevented by adopting the above two-stage reduction treatment, the burning of a reducing furnace can be prevented.

Abstract: PURPOSE:To prevent a piston from sticking due to the thermal-expansion of a wear ring 1 by forming cut portions at upper and lower edges of a groove for receiving a wear ring of a Stirling engine. CONSTITUTION:A annular groove 3a receiving a wear ring 1 for sealing a lublicating oil or the like is formed in the lower portion of a piston 3 of a Stirling engine. The upper and lower portions of the annular groove 3a are respectively provided with cut portions 3c which introduce thereinto thermally expanded portions of the over-heated wear ring 1.
