Title: Controller for dissolved oxygen concentration of condensed water
Inventor: IGARASHI NOBORU
IPC: G21D1/00
Filed: 1981-03-02
Abstract: PURPOSE:To raise the dissolved oxygen concentration of condensed water by providing an oxygen storage tank whose lower end is opened in a water condenser in a device in which oxygen is dissolved in the condensed water in order to prevent the corrosion of the inside of the condenser used in power generation plants, etc. CONSTITUTION:A hot well 12 to store condened water is formed in the lower part of a water cndenser cylinder 11, and an oxygen storage tank 15 is provided on the upper part of the hot well whose one end is provided with a partition plate 18. Oxygen supplied from an oxygen jet nozzle 20 goes up inside the hot well 12 and is stored in the oxygen storage tank 15, whereupon the pressure of the stored oxygen becomes one corresponding to a water head pressure resulting from the difference in water level between the condensed water in the storage tank 15 and the condesned water in the hot well. Thus, even when the inside of the water condenser is evacuated to 30-40mm.Hg, the dissolving rate of oxygen can be raised. Also, the pressure of storated oxygen can be regulated by latering the length of the partition plate 18.

Title: Rotary connector
Inventor: HASEGAWA MASAHIRO
IPC: H01R35/04
Filed: 1997-01-29
Abstract: PROBLEM TO BE SOLVED: To prevent a flat cable from loosening in the width direction when an automobile travels on a gentle curve by maintaining an interval between the flat cable and a vibration damping plate in a closely adjacent condition when angular acceleration of steering is comparatively small, and expanding it when the angular acceleration becomes large. SOLUTION: A flat cable is housed in an almost annular ring-shaped space 3 between an inside case 10 and an outside case 20 of a rotary connector 100, and a vibration damping plate 12 is arranged by leaving a slight clearance between it and the cable 1. The vibration damping plate 12 is composed of a support projecting part 12a, a wall 12b and an elastic body 12c, and is formed as a structure that a clearance between the elastic body 12c and the cable 1 expands by the action with a pin 13 to engage with the wall 12b when the support projecting part 12a is rotated at comparatively large angular acceleration by steering. Therefore, in a condition where the steering rests or rotates at comparatively small angular acceleration, the vibration damping plate 12 is put in a condition of most approaching the cable 1, and looseness of the cable 1 can be prevented.

IPC: H01L21/76
Filed: 1987-02-12
Abstract: PURPOSE:To prevent leaks between clements by a method wherein an insulating body buried in a groove in a semiconductor substrate is subjected to an etch- back process which continues until the insulating body is lower than the substrate surface, polycrystalline silicon is then buried in the groove and oxidized, and another etch-back process is accomplished for the formation of an isolating region with its surface flattened. CONSTITUTION:A groove is provided in an isolating region on the surface of a silicon substrate 1, to be filled up by silicon oxide. An etch-back process is accomplished, which continues until the silicon oxide is lower than the surface of the substrate 1. Next, the groove is filled up with polycrystalline silicon 4, which is then oxidized. Another etch-back process is accomplished, which results in an isolating region 6 with silicon oxide 15 retained. No dents are to be produced because the surface of the isolating region 6 is uniformly etchant- resistant. A process follows wherein an Al electrode 7 is built, an interlayer insulating film 20 is formed, an Al electrode 8 is built, and then etching is performed. The result is an isolating region with its surface flattened, which prevents leaks between elements.

Title: Torsion damper for motor vehicle clutch friction plate
IPC: F16F15/129
Filed: 1993-01-28
Abstract: PURPOSE: To form a torsion damper simply and inexpensively and improve the surface of cutting portion and extend service life by cut-forming a slot from a hub plate using laser beam. CONSTITUTION: A slot 28 of a hub plate 11 is formed by cutting the hub plate 11 using laser beam 401. It is desirable to form the edge of slot 28 by the generation of beam 401 moving the laser and focussing to a small diameter. A metal slag is produced in cutting, however, this is removed by falling in the end of cutting operation. An excellent surface condition can be formed in the edge of slot 28 using laser, thereby, springs 27a, 27b are seated well there and accordingly a clutch friction plate is actuated satisfactorily. This effect brings about a kind of annealing effects by the heating of laser beam and is increased by the hardening of slot edge.
