Title: Pressure control system
Inventor: OGINO HIROHIKO
IPC: F16L55/04
Filed: 1990-11-20
Abstract: PURPOSE:To reduce surge pressure and to suppress oscillation and noise by comparing the intra-pipe pressure Pr of the 2nd pipeline with atmosphere Po, and at the time of Pr<Po, reducing the sectional area of the passage of the 2nd pipeline. CONSTITUTION:Return pressure Pr from a pressure control value is applied to a pressure room 27e through an upstream side port 27a and a passage 27d, and when the sectional area of a spool 27h on the pressure room (27e) side is defined as Sa, down force Fd with Sa X Pa power is applied to the spool 27h. When the spool sectional area on the atmosphere room (27g) side is defined as Sb, up force Fu with Sb X Po power is applied to the spool 27h. When the return pressure Pr is reduced less than the atmosphere pressure Po, Fd<Fu is formed, the spool 27h is moved upward and the sectional area of an oil passage 27c is reduced. Consequently, the consumption of energy for the generation of foams or the smash of foams can be suppressed, the generation of surge pressure can be reduced and the generation of oscillation or noise can be suppressed.

Title: Motor
Inventor: KAWAI HIROYOSHI
IPC: F03D9/00
Filed: 1998-11-09
Abstract: PROBLEM TO BE SOLVED: To improve the power generation efficiency without an intense flow by arranging a means for increasing the flow velocity or a flow rate of fluid butting a rotor in a motor including the rotor rotated by receiving the fluid and a generator converting the rotating force of the rotary vane into an electric energy. SOLUTION: When an introduced wind is blown in from a take-in window in front of a take-in box, a fan 2 is rotated and the shaft of the fan 2 penetrated through a partition board 18 and connected to a drum 1 rotates a hollow drum 1. When the introduction wind is blown from the take-in window in front of the take-in box 8, it acts on the rotating drum 1 to accelerate the flow velocity of the introduction wind in the lower part of the drum 1 by Magnus effect and causes a pressure reducing phenomenon. On the other hand, a suction wind is energetically sucked from a bottom suction hole in the bottom of the take-in box 8 to blow therethrough as an exhaust wind. The suction wind applies a rotating force to a rotor in the entrance of the suction wind duct linked with the bottom of the take-in box 8 and converts it into an electric energy by the interlinked motor.

Abstract: PURPOSE:To enable continuous gradation recording of good linearity to used energy and a large dynamic range by executing recording by a difference in the degree of crystallization between a recording part and non-recording part. CONSTITUTION:An 830nm semiconductor 1 is polarized through a polarizing beam splitter 2 and a quarter-wave plate 3 to circular polarized light which is then focused by an objective lens 4 onto a recording medium 5.

The high-polymer liquid crystal 7b is transparent and has about 40% reflectivity ion this state, but the reflectivity changes in approximately proportional to the laser irradiation time when laser light is projected to such liquid crystal. The continuous gradation recording is thereby enabled.
