Title: Ion implanting device
Inventor: KOIKE YUKIO
IPC: H01J37/317
Filed: 1992-03-03
Abstract: PURPOSE:To stabilize the ion implantation, and especially to stabilize the control in the direction of the depth in the ion implantation, by feeding a high purity of plasma to the ion beams while excuding a neutral gas, when the plasma is fed to the ion beams so as to neutralize the electric charge, in order to prevent a chargeup of the surface of a substance to be processed. CONSTITUTION:While a chamber 13 for producing plasma is set separated a little from an ion beam radiating passage in a Faraday cup 8, the chamber 13 for producing plasma and the Faraday cup 8 are connected through a magnetic field coil 14. While the plasma is led into the ion beam radiating passage along a magnetic field formed by the magnetic field coil 14, a neutral gas which receives no influence of the magnetic field is separated and removed from the plasma.

Filed: 1986-04-09
Abstract: PURPOSE:To attain the cost-down by fixing the gain of a variable gain adjusting device in receiving a conventional FM broadcast so as to eliminate the need for a switch circuit switching the sub signal. CONSTITUTION:In receiving a conventional FM broadcast, the gain of a variable gain adjusting device VCA 11 is fixed forcibly to the unity by a variable gain adjusting device control circuit 17. Since no signal component appears at the output of a sub detector 6 in this case, a sub signal being an output of a sub detector 5 is inputted to a matrix circuit 15. On the other hand, in receiving a new type FM stereo broadcast, a switch circuit 16 is turned on and the circuit 17 is not activated, then either the sub signal or a signal applying 90 deg. orthogonal modulation to the said sub signal is inputted to the circuit 15.

IPC: B01D11/00
Filed: 1988-04-02
Abstract: PURPOSE:To efficiently obtain high purity indole useful as raw material of tryptophan, perfume and the like from crude indole obtained from coal tar fraction, by removing impurities using carbon dioxide in a liquid or supercritical gas state. CONSTITUTION:Impurities such as methylnaphthalene are selectively extracted (1) and removed (6) from crude indole obtained by well-known method from coal tar fraction using carbon dioxide (2) in a liquid or super critical gas state preferably under a pressure of 70-300atm. and at a temperature of 30-60 deg.C, thus highly purified indole is efficiently obtained using carbon dioxide, which is of low price, harmless to human body and safe because of incombustibility, as a solvent. Besides, the method is not necessary of distillation for recovery of solvent, which is readily performed by reducing pressure or rising of temperature, and any retention of used solvent or impurities therefrom is not produced. Furthermore, any effect of heating such as change of properties, oxidation or polymerization is not produced because of low temperature-treatment.

Title: Optical coupler
Inventor: TOMITA TADAHARU
IPC: G02B6/30
Filed: 1987-04-03
Abstract: PURPOSE:To turn on and off optical coupling and to discriminate the frequency of light, by coupling an optical fiber with a thin-film optical waveguide film by means of a magnetic fluid and electrically controlling the shape and position of the magnetic fluid by using a magnetic field. CONSTITUTION:A leakage magnetic field is produced by a magnetic pole 5 and a magnetic fluid 2 is held by the magnetic field. The magnetic fluid 2 is placed between a thin-film optical waveguide 3 and the optical fiber 1 and incident light 6 is totally reflected by the inner surface of the fluid 2 and injected into the optical waveguide 3. When the leakage magnetic flux from the magnetic pole 5 is reduced, the leakage magnetic flux hardly reaches the magnetic fluid 2 and the shape of the fluid 2 changes from a semicircle to an elliptic form. Accordingly, the top T of the fluid 2 becomes lower than the incident light 6 in elevation and no optical coupling takes place in such state. Therefore, turning on an turning off of the light can be made easily and, moreover, frequency separation of light which is not high in resolution can be performed by means of the angle formed by the incident light and inner surface of the magnetic fluid.

Filed: 1991-04-16
Abstract: PURPOSE:To reduce the time required for performing a pull-up resistance disconnecting process so as to reduce the power by adding a level setting resistance (pull-up resistance) permit flag. CONSTITUTION:A pull-up resistance permit flag 65 and AND gates 81 and 82 are added to an input-output circuit 70.

Therefore, all pull-up resistances are disconnected. The same can be said to each input-output control circuit ill of another input-output port 61. In addition, when the pull-up resistance permit flag is added to each input-output port and the ports are mapped to the same address, the control of connection and disconnection of the pull-up resistances become possible at every input-output port.

Abstract: PURPOSE:To ensure a necessary and proper lift amount for providing a compact and light-weight high-speed fuel injection valve with a simple construction by the use of a piezo-electric body in a device for obtaining high speed response to opening and closing the valve. CONSTITUTION:The interior of a valve body 12 is divided into a piezo-electric body chamber 14 and a fuel chamber 15 which is formed with a high pressure fuel inlet 16 and an outlet 17. When the valve is opened, a piezo-electric body 25 for opening and closing the valve oscillates mechanically with the same frequency as applied high frequency electric field to oscillate an oscillating piece 28 which slants its end to the opposite side to a rod 19. Since said end is pressed against one surface 18a of a plunger 18, the plunger 18 moves rightward in the drawing to open the valve, while a piezo-electric body 30 for closing the valve does not block the valve opening operation by the help of a certain electric field application. On the other hand, in the closing of the valve, the plunger 18 moves leftward by the same action as the above mentioned.

Title: Vapor growth device
IPC: H01L21/205
Filed: 1992-04-06
Abstract: PURPOSE:To form a good vapor growth film with high producibility by constituting a tubular reaction pipe partially of a section tapered in two steps and by supplying introduced reaction gas to a semiconductor wafer uniformly by lowering it while spreading gradually. CONSTITUTION:A susceptor 2 whereon a plurality of semiconductor wafers 6 are mounted is rotated at a fast speed and reaction gas is introduced into a reaction pipe 1. Then, the reaction gas flows downward while spreading gradually along tapered section of the pipe 1b at a first stage and attains near a surface of the semiconductor wafer 6 by centrifugal force by fast rotation of the susceptor 2. Furthermore, it passes through between the susceptor 2 and a tapered section 1C at a second stage and is evacuated downward along a spreading surface of the tapered section 1C at the second step. Since reaction gas lowers while spreading gradually inside the reaction pipe and is supplied to a semiconductor wafer, the reaction gas can be uniformly supplied to the semiconductor wafer and a vapor growth film of good film quality and film thickness can be acquired.
