Title: Surface processing method for magnetic disk
Inventor: SATAKE TAIICHI
IPC: G11B5/738
Filed: 1986-04-21
Abstract: PURPOSE:To improve the durability of a magnetic disk and to enable the formation of a uniform plated film by making the pretreated surface of a nonmagnetic substrate uneven and polishing the uneven surface before the formation of a magnetic film so as to bring a head into plane contact with the resulting disk. CONSTITUTION:A nonmagnetic substrate 1 is pretreated to form an underlayer 2 and this underlayer 2 is polished. An abrasive tape is pressed on the surface of the underlayer 2 and the surface is made uneven by relatively moving the tape and the substrate 1. The uneven surface is polished again with free abrasive grains whose grain size is smaller than that of the abrasive tape and then a magnetic film 3 is formed by electroless plating. A head is brought into plane contact with the resulting magnetic disk to improve the durability of the disk and the plated film can be satisfactorily formed.

Title: Fail safe device for ignition control device for internal combustion engine
Inventor: TOMIZAWA NAOMI
IPC: F02P5/15
Filed: 1988-04-15
Abstract: PURPOSE:To enable the common use of a hardware and to enable reduction of a cost, by a method wherein, in a device which stops an ignition signal from a microcomputer during the occurrence of abnormality and outputs an ignition signal from a different output means, the output means is so formed that an ignition signal is outputted at intervals of a given time. CONSTITUTION:During running of an engine, a microcomputer 20 inputs a reference signal REF from a crank angle sensor and a position signal POS to generate an ignition signal at an optimum timing responding to an engine running condition, and outputs the ignition signal to an ignition device 22 through a switching circuit 21. In this case, a program run signal inverted at a given period is monitored by a run away monitoring circuit 23, and when the period is out of a given range, it is decided that the microcomputer 20 is in a run-away state to output a reset signal. This constitution causes switching of the switching circuit 21 by means of a microcomputer abnormality detecting circuit 24 when abnormality occurs, and outputs an ignition signal, generated at intervals of a given time by a dividing circuit 25, to the ignition device 22.

Inventor: ISHIHARA TADASHI
IPC: F16H3/42
Filed: 1982-05-29
Abstract: PURPOSE:To obtain a stepless speed changer, in which power is surely transmitted, by performing stepless speed change action through a gear mechanism. CONSTITUTION:When idlers 5, moved along sloped surfaces 18 of speed change plates 13, 13, are meshed with a worm tooth 4 in a position (a), the idlers 5 successively perform parallel movement around a worm gear 3 at a tilt angle beta of the surface 18 in accordance with rotation of a gear 2. If the angle beta of the surface of the plate 13 is increased for a tilt angle alpha of the tooth 4 of the worm gear, a rack of the idler 5 moves while sliding on the tooth 4 to transmit driving power to the gear 3, in consequence rotation of the gear 2 is reducibly transmitted. In case of the angles where alpha=beta, the idler 5 is only slided along a surface of the gear 3, and power is not transmitted to the gear 3.

Title: Refrigerating plant
Inventor: KASEZAWA MINORU
IPC: F25B1/047
Filed: 1992-04-13
Abstract: PURPOSE:To prevent the compression of oil at the restarting of a refrigerator and attempt a stabilized start and oil supply by releasing a refrigerant gas in an oil separator into a suction side of a compressor while halting the operation of each screw compressor based on a two stage and a single stage which constitutes a part of a three stage compression refrigeration cycle. CONSTITUTION:A two stage screw compressor is used on a lower pressure side and a single stage is further used on a higher stage side while an oil separator, an oil tank, a condenser, an expansion valve, a vaporizer and the like are connected with a piping system, thereby constituting a three stage compression refrigeration cycle. While each of the two stage and single stage screw compressors suspends each operation, the refrigerant gas in the oil separator is released into the suction side of the compressor. More specifically, while the refrigerator halts its operation, power is supplied to the coil of a time limit relay 14 and a bypass solenoid valve 13 is turned into an open state during this setting time, thereby bypassing the refrigerant gas in the oil separator into the two stage compressor side and forcing the refrigerator oil in the single stage compressor side to flow into the two stage compressor side as well. It is, therefore, possible to prevent oil compression during restarting.
