Title: Manufacture of structural alloy steel for cold forging and for cutting
Inventor: FUKUNAGA SHIYUUZOU
IPC: C21D8/00
Filed: 1982-11-29
Abstract: PURPOSE:To improve the cold forgeability and machinability of a medium or low-carbon low-alloy steel having a specified carbon equiv. by forming the steel into a wire rod or a bar by hot rolling, and cooling it at a specified cooling rate to provide a ferrite-pearlite structure. CONSTITUTION:The carbon equiv. Ceq of a medium- or low-carbon low-alloy steel represented by equation I is regulated to <=0.88%. For example, the composition of the steel is composed of, by weight, 0.2-0.5% C, 0.15-0.35% Si, 0.4-1% Mn, 0.5-1.5% Cr, 0.1-0.3% Mo and the balance Fe. The steel is formed into a wire rod or a bar by hot rolling and cooled to 500 deg.C at a cooling rate Vc ( deg.C/sec) represented by equation II [where TR is the finish rolling temp. ( deg.C)] to convert the structure of the steel into a ferrite-pearlite structure.

Title: Method for regenerating reprocessed organic solvent
Inventor: UCHIYAMA GUNZOU
IPC: C07F9/11
Filed: 1991-05-17
Abstract: PURPOSE:To prevent the formation of secondary waste and an unstable nitrogenous compound, in the regeneration of an organic solvent having as the main component tributyl phosphate used in a nuclear fuel reprocessing process. CONSTITUTION:An organic solvent having tributyl phosphate as the main component can be regenerated, by using a butylamine reagent (butylamine carbonate, butylamine oxalate) in the washing of the solvent, with no possibility of formation of the secondary waste and the unstable nitrogenous compound, because the reagent is resolved into nitrogen dioxide, carbon dioxide and water without forming an unstable nitrogenous compound due to lack of N=N bond.

Title: Remote control equipment
Inventor: ASANO KAZUTAKA
IPC: G05B24/02
Filed: 1985-09-20
Abstract: PURPOSE:To prevent the system breakdown with a remote control equipped by adding an equipment main body/remote operating part identification code to an address code in a signal packet and identifying the reception signal for the equipment main body from that for the remote operating part by said identification code via a transmitting microcomputer. CONSTITUTION:The transmission of a remote operating part 26 is delayed by some reason and other remote operating parts waits for the transmission carried out by an equipment main body 25. Under such conditions, the part 26 performs the transmission and each remote operating part receives the signal packet of the part 26 to decode an address code from the signal packet. Then the remote operating part reads the final bit '1' of the equipment main body/ remote operating part identification code '0101'. Thus the remote operating parts excepting the part 26 can judge that the received data is not sent from the main body 25 but from either one of those remote operating parts and therefore can wait immediately for the transmission of the main body 25 without carrying out any processing after reception.

Abstract: PURPOSE:To achieve a lower cost of a piezoelectric buzzer driving circuit by making the piezoelectric buzzer driving circuit serve as a part of a step motor driving circuit. CONSTITUTION:When a piezoelectric buzzer driving circuit is used as a step motor driving circuit, points (a) and (b') are short circuited to equialize the potential between points (c) and (d') thereby checking effect of a piezoelectric buzzer  5 and a driving signal is applied to the points (a) and (b) alternately. When it is used as such, points (a) and (b) are short circuited to equialize the potential between the points (c) and (d) thereby checking effect of an excitation coil 5 and an inverted signal is applied to the points (a) and (b'). This permits separate driving of the excitation coil 5 and a piezoelectric buzzer 6 without affecting each other despite the combined use of a P-MOS1'' and N-MOS2''. Such an integration can decrease the area of a driving circuit requiring a large area thereby achieving a lower cost.
