Title: Gate valve device for high vacuum
Inventor: IRIE NORIKIMI
IPC: F16K31/12
Filed: 1989-07-21
Abstract: PURPOSE:To isolate a high vacuum system from the atmosphere in a short time in an emergency shutdown for minimizing a drop in the degree of vacuum and enable resetting in a short time by providing a normal use pressure source for normally opening and closing operation, and a high pressure source for emergency shutdown respectively as operation media sources for an valve opening and closing air cylinder device. CONSTITUTION:In the normal opening and closing operation of a gate valve device, the normal operation air pressure of approximately 5 atm. or less is introduced to a valve opening and closing air cylinder device 24, thereby moving a gate plate 17 to a valve port open or close position. In an emergency like vacuum break, a fuse 35, for example, is supplied with a large amount of electric current and instantaneously burnt. As a result, a resin layer 36 such as Derlin formed on the surface of the fuse 35 vaporizes due to generated heat. Gas pressure approximately 10 times as large as the normal air pressure for normal opening and closing operation is thereby generated within the valve closing side chamber 33 of the valve opening and closing air cylinder device 24, and a piston 25 is suddenly operated with a large force. According to the aforesaid construction, a valve port can be quickly closed with a minimum time delay.

Title: Schottky gate field effect transistor
Inventor: SUZUKI TOMIHIRO
IPC: H01L27/095
Filed: 1986-08-11
Abstract: PURPOSE:To decrease dispersion on the drain conductance by taking a larger width of an operating layer in comparison with a gate width of a gate electrode. CONSTITUTION:A metal Schottky type field effect transistor (MESFET) is composed of electrodes of source 3 and drain 4 which are arranged by isolating each other on an operating layer 2 formed on a semiinsulating semiconductor substrate 1 such as GaAs and furthermore come in ohmic contact with the operating layer 2. On the other hand, a Schottky type gate electrode 6 which is formed between electrodes of source 3 and drain 4 does not cross completely an upper part of the operating layer 2, resulting in the formation of a current pass having a width WP which is not controlled by the gate electrode. Since the current pass functions as a parallel resistance between the electrodes of source and drain, dispersion on the drain conductance gd can be minimized by designing the width WP so that the conductance for the parallel resistance can come to a main term for the drain conductance gd.

IPC: G03G15/00
Filed: 1993-07-29
Abstract: PURPOSE:To obtain an image with uniform density even when dark attenuation on a photoreceptor film is fluctuated by changing the electrostatic charging ability of an electrostatic charging means based on the fluctuation of the degree of the detected dark attenuation. CONSTITUTION:By a surface potential sensor 40, the surface potential Vs of the photoreceptor film 23 attenuated by the dark attenuation after it is electrostatically charged by a main electrostatic charger 25 is read.

Title: Optical coherent receiver
Inventor: TAKEYARI RIYOUJI
IPC: H04B10/61
Filed: 1991-07-29
Abstract: PURPOSE:To prevent a frequency from being jumped in the case of switching an AFC operation and a tuning operation by inputting a tuning signal to the integrator of the AFC circuit. CONSTITUTION:In the case of switching a channel to a long wavelength side, a switch 9 is changed over to a (+) constant voltage source 7a. The output (integrated value) of an integrator 10 is increased at fixed speed, the injecting current of a local oscillation laser 12 is increased, a temperature is increased and therefore, an oscillated wavelength is shifted to the long wavelength side. Namely, when the switch 9 is changed over to the side of the (+) voltage source 7a, the local oscillated wavelength is swept in a long wavelength direction on a wavelength axis at fixed speed. In the case of switching the channel to a short wavelength side, it is achieved by changing over the switch 9 reversely to the side of a (-) voltage source 7b. Thus, the output of the integrator 10 is continued without affected by the AFC and tuning operations, and the integrator can stably be operated without generating jumping of the local oscillated wavelength in the case of switching the operations.

Filed: 1988-07-28
Abstract: PURPOSE:To realize the front-back adjustment of a pedal by moving front and back the position of a pedal pad in accordance with the height of an operator to secure a proper position, then moving a pedal arm in parallel with the pad to keep this pad at the fixed height. CONSTITUTION:The position of a pedal pad 22 is controlled when a pedal arm 18 is moved toward an operator. When a screw nut 19 is moved via a motor, a pin 17 moves along an arc-shaped hole 6b and at the same time a pin 8 is pushed downward along an arc-shaped hole 7 of a lever 3. While a link 9 turns clockwise around an axis 12 of a sublever 11. The pin 8 moves along the hole 7, and the distance DS between an axis 2 and the pin 8 varies in proportion to the distance DL between the axis 2 and the pad 22. A tension spring 15 functions to keep the lever 3 at a fixed position. The pad 22 is treadled after its position is adjusted. Thus both the arm 18 and the lever 3 turn clockwise around the axis 2 to move a control lever 13 to the left.

Title: Closed type air-spring device
Inventor: TAKAYAMA KEIICHI
IPC: F16F9/02
Filed: 1982-10-29
Abstract: PURPOSE:To make it usable as a small and lightweight desk-top type as well as to make the deflection of a surface plate or the like attendant upon movements and so on correctable in an automatic manner, by installing a surge tank and a level detection mechanism, while feeding an air spring with air from the tank in time of detecting some variations. CONSTITUTION:When air is fed to a surge tank 5 from an air feed port 7 by a hand pump or the like, the air enters an air spring 1 by way of the surge tank 5, an opened, normally closed valve 4, a check valve 3, expanding this air spring in an axial direction and making a surface plate A go up. When air pressure reaches the specified value, the surface plate becomes the specified level and the valve 4 is automatically closed whereby air feed to the air spring 1 is stopped. With an air leak, movements of a heavy load, etc., if the spring 1 sinks to a lower level, the valve 4 is opened and air is replenished to the spring 1 from the surge tank 5. This replenishment is stopped when the valve 4 is closed as the air quantity becomes the specified level. That is to say, since level adjustment can be automatically performed in case of this air spring being small in size and ease of motion, it is usable as a desk-top type air spring.
