Title: Variable capacity type hydraulic apparatus
Inventor: HORIUCHI TAKESHI
IPC: F04B1/26
Filed: 1980-11-12
Abstract: PURPOSE: To enable a long-run control and a constant power control by applying reduced pressure of high pressure side pressure of a hydraulic apparatus upon a control cylinder which adjudts displacement capacity of a swash plate, etc.  
     CONSTITUTION: A part of deliverd fluid which flows through a delivery passage 17 is taken in a connecting passage 20. After its pressure is reduced to a fixed pressure by a proportional pressure reducing valve 60, it is applied upon a back chamber 14 of a control plunger 14 via a control passage 20a. The control plunger 14 does not operate even when reduced pressure is applied upon the control plunger 14 and a swash plate 6 is kept at the maximum tilt angle. When reduced pressure exceeds a fixed pressure it overcomes pushing pressure of a bias plunger 13 and the control plunger 14 moves. Control pressure is obtained according to the characteristics of reducing valve 60. By increasing its reduced pressure ratio, a control pressure with less initial rise in proportion to the rise of high pressure side pressure and a long-run control conducted.

Filed: 1981-10-07
Abstract: PURPOSE:To obtain optical fiber having extremely improved transmission  characteristics by a simple device and operation under mild reaction conditions, by replacing H of the hydroxyl group of a hydrolyzing reagent in the raw material with deuterium in the preparation of optical fiber by a solution method. CONSTITUTION:In the preparation of optical fiber using ethyl silicate as a raw material, water and ethanol are used as hydrolyzing reagents for ethyl silicate, wherein water having deuterated H and ethanol having deuterated H of OH group are used. Namely, when ethyl silicate in the reactor 1 is mixed and hydrolyzed with D2O and C2H5OD, silicate gel 3 containing almost no OH is obtained. The gel is spun and heat-treated in such a way that OH group will not be introduced afterward, to give the optical fiber 6. It has an extremely small amount of OH bonds having harmful absorption for transmission characteristics in near infrared ray region, and they are almost replaced by the OD bonds having extremely small harmful absorption, so the transmission characteristics are much improved.

Filed: 1995-06-27
Abstract: PURPOSE: To prevent the medium-pressure steam quantity used for cooling the tail pipe of a gas turbine from becoming lower than the required quantity during the partial load operation of a steam turbine by squeezing the high- pressure governor valve of the steam turbine to increase the medium-pressure steam generation quantity during the partial load operation of the steam turbine. CONSTITUTION: The medium-pressure steam of an exhaust heat recovering boiler 10 is extracted, and cooling steam is fed to the combustor tail pipe of a gas turbine 4. When the governor valve 7 of a high-pressure steam turbine 1 is squeezed, the steam pressure of the high-pressure drum 17 of the exhaust heat recovering boiler 10 rises. When the steam pressure of the high-pressure drum 17 rises, the steam generation quantity by a high-pressure evaporator 12 is decreased. The heat quantity is fed to a medium-pressure evaporator 14 that much, and the steam generation quantity by the medium-pressure evaporator 14 is increased. When the governor valve 7 of the high-pressure steam turbine 1 is squeezed during the partial load operation of the steam turbine 1, the medium-pressure steam quantity required for cooling the tail pipe can be supplied during the partial load operation.

Abstract: PROBLEM TO BE SOLVED: To attain the stable supply of water and the reduction of water rates by connecting a ground water supply pipe and a city-water supply pipe having valves respectively to one receiving tank while preferentially supplying ground water in response to the usage of water. SOLUTION: When the water level of a receiving tank 14 is made lower than the first level A (the case of water filling) at a normal time, a solenoid valve 27 is opened by operating a level sensor 29 during a time when the lowering position is placed between the first level and the second level B, and the device is controlled so that ground water is fed and the first level A is held. When ground water is not supplied even when trouble is generated in a ground water supply system and the water level is made lower than the first level A, a ball tap 24 is lowered, and a valve 21 is opened, and city water is fed. When an extremely large quantity of water are used and the water level is made lower than the fourth level D, an electrode 29b detects the lowering and the solenoid valve is opened, and the valve 21 is also opened and city water is fed.  Accordingly, water is supplied stably while city water can be economized.
