Title: Speed change gear
Inventor: ORIHARA SUSUMU
IPC: H02P15/00
Filed: 1989-09-14
Abstract: PURPOSE:To smoothly change the speed by making selection out of two pairs of gears having different gear ratios which are installed between a driving shaft driven by a clutch, which is connected and disconnected specific times repeatedly within a specific period and linked, and a driven shaft. CONSTITUTION:A clutch 18 is connected and disconnected by the output of a clutch controller 21 specific times repeatedly within a specific period and linked to a driving shaft 12. When the clutch 18 is linked, the rotation of the driving shaft 12 is transmitted to a driven shaft 13 from a gear 15 through a gear 17. When the clutch 18 is disconnected, the rotation of the driving shaft 12 is transmitted to the driven shaft 13 from a gear 14 through a gear 16 having a one-way rotation clutch 19. The gear ratio between the gears 14 and 16 is larger than that between the gears 15 and 17. The rotation speed of the driven shaft 13, when the gears 15 and 17 engaging with each other are used, is higher than that when the gears 14 and 16 engaging with each other are used. Thereby the speed of the driven shaft 13 can be easily changed. This invention is preferably applied to the cash dispensers of the financial institutions, shortening the working time.

Filed: 1990-09-11
Abstract: PURPOSE:To produce polyethylenepolyamine from ethyleneamine and ethanolamine on an industrial scale at a low cost by using a catalyst having long life and produced by adding titania to niobium oxide supported on alumina. CONSTITUTION:A highly active catalyst is prepared by contacting a solid alumina carrier with a non-solid niobium-containing substance, converting the non- solid niobium substance into solid niobium oxide, contacting the oxide with a non-solid Ti-containing substance and converting the Ti-containing substance into titania. A polyethylenepolyamine is produced from ethyleneamine and ethanolamine using the obtained catalyst. The catalyst has high activity and causes little lowering of the activity even after repeated use or continuous use over a long period. It is an extremely important industrial catalyst.

This voltage is set to a prescribed value by resistors 15, 16 and 17 and formed into the threshold voltage of identification circuits 11, 11'. When the DC level of the signal (e) is lowered, the threshold voltage is also lowered.
