Title: Voltage maintaining device
Inventor: OKAMURA SHIROU
IPC: G11C27/00
Filed: 1979-11-19
Abstract: PURPOSE: To make it possible to maintain the voltage with simple circuits by compensating the voltage of the 1st capacitor which discharges at a small time constant, with charging at the voltage of the 2nd capacitor which discharges at a large time constant.  
     CONSTITUTION: Input signals from temperature detecting section composed of resistance 8 and thermistor temperature sensing part 9, are introduced to capacitor 10 which discharges at relatively small time constant J 1  and processing circuit 3 through diode 7. On the other hand, when switch 12 is opened when a memory request is made, capacitor 11 slowly discharges the voltage of that time at a given time constant J 2 . Since switch 14 continues on and off when switch 12 is opened, discharge voltage of capacitor 11 recharges capacitor 10 and compensate the fall of potential through differential amplifier 15 and diode 16. Thus, when the gain of amplifier is selected properly, the voltage of capacitor C 1  can be maintained.

Abstract: PURPOSE:To effectively manufacture parts made of ceramics by entering ceramics sintered body in a vessel containing a polishing liquid, grinding particles and media, and by giving them movement. CONSTITUTION:Materials 1 made of ceramics sintered body are combinedly machined. After the corners of the materials 1 are made to be round, they are finish-machined. When a plurality of materials 1 are entered in a vessel 2 together with grinding particles and media 3 and a polishing liquid 4, and when the vessel 2 is rotated, the materials 1 in the vessel 2 are stirred with the particles and media 3 and the polishing liquid 4. Then, as the materials 1 strike against the particles and media 3, unevenness on the surface of the materials 1 is eliminated, and polishing thereon is thus carried out. The materials are also fully brought into contact with the grinding liquid 4, and the surfaces which are still uneven are corroded and melted, namely subjected to etching, by the liquid 4 to have smooth surfaces. It is thus possible to effectively remove the corners of materials 1 to form them in spherical shapes and finish-machine the surfaces of the materials 1 smoothly according to the simultaneous works of the grinding of grinding particles and media 3 and the chemical treatment of the grinding liquid 4.
