Abstract: PURPOSE:To execute the positioning control of high cost-performance with a simple composition, by executing an original point reset processing sequence according to the detecting signal of a near original point position sensor and the detecting signal of an original point position sensor. CONSTITUTION:When an object 6 to be moved is moved and the moved object 6 is detected by a near original point position sensor 7, the object 6 is decelerated and stopped once. After that, again, the object 6 is moved in the direction of an original point. When the object 6 is detected by an original point position sensor 8, the object 6 is decelerated and stopped. By such a sequence, the moved object 6 is returned to the position of the original point.

IPC: G05B19/418
Filed: 1989-01-10
Abstract: PURPOSE:To minimize the tact time and to improve the production efficiency of a mass production line by deciding the control states of axis control means via a main control means and performing the synchronism waiting control between the axes of the axis control means. CONSTITUTION:A main control means 1 consists of a communication protocol control means 1, an inter-system control means 12, a tape memory means 13, and a PC control means 14. The means 14 is connected to the axis control means 2a and 2b via the serial link control circuits SLC 21a and 21b and the communication circuits L1 - L3 respectively. Then the means 1 is linked with the means 2a and 2b via a serial data line. In other words, the means 1 transfers the inter-axis waiting state signal to each axis control means as necessary via such a communication line. Thus the inter-axis synchronism waiting control is attained with a high speed and simple program. Then the production efficiency of a transfer line is improved.

Filed: 1988-01-12
Abstract: PURPOSE:To obtain a fingerprint picture of good quality immediately when a finger is placed even in the case of a person who sweats little by placing a porous glass on a rectangular prism or a plate glass and supplying water thereon. CONSTITUTION:A rectangular prism 1 or the plate glass and a porous glass 2 placed on it with a slight space kept on it are provided and water 10 is supplied between the porous glass 2 and the rectangular prism 1 or the plate glass.

Especially when the title device is composed so as to satisfy all reflection conditions, all the reflection conditions break in accordance with the fingerprint and the light of a lamp 4 reaches the skin of the finger and reflects irregularly. In the parts of the valleys of the fingerprint where the skin is not in contact with the porous glass 2, it reflects wholly. Consequently, a camera 5 detects the difference in the quantity of reflected light of the parts of ridges and the parts of the valleys of the fingerprint as the fingerprint picture and when a finger 9 is laid, the fingerprint picture of good quality can be obtained even in the case of a person who sweats little.

Title: Positioner
Inventor: KURIHARA MITSURU
IPC: B61B13/08
Filed: 1989-01-11
Abstract: PURPOSE:To facilitate positioning when a moving body is supported noncontactingly by causing DC current flowing in the same direction to flow into a gap section of a magnetic circuit having two spots of gap equal in area but reverse in the flux direction. CONSTITUTION:When a switch 8 is closed and the current is caused to flow from a DC power source 7 to a coil 5, a brake will act. Here, when the area of a coil 5 to cross gap sections 3 and 3' is equal, the forces A and B acting respectively on the gap sections 3 and 3' are reverse in the direction but equal in strength, so that the forces are balanced and the moving body 4 comes to a standstill. On the other hand, in the condition where the moving body 4 causes misregistration in the right and left directions against the coil 5, only the area of the coil 5 crossing the gap 3' on the right is decreased and the outward force B' acting on the gap section 3' is decreased accordingly. The balance of force is lost and the moving body 4 moves in the direction of an arrow C. Positioning can thereby be made easily when the moving body is supported non-contactingly such as in air levitation or in magnetic levitation.

Title: Snubber circuit of semiconductor device
Inventor: IGARASHI MASATERU
IPC: H02M1/06
Filed: 1995-01-18
Abstract: PURPOSE: To reduce generated loss and reduce the size by providing an insulation gate type bipolar transistor(TR), a capacitor, and a resistance. CONSTITUTION: A voltage driven type thyristor turns OFF, a main current I0 is ceased, and a main power source I0 shifts to the snubber circuit 6, thereby obtaining a snubber current IS. The snubber current IS flows to a main circuit through a capacitor 2, a resistance 3, and an insulation gate type bipolar TR IGBT4. A current IIGBT flowing to the IGBT4 is generated by generating a resistance voltage VR across a resistance 3 with a resistance current IR, applying this resistance voltage VR as a gate voltage to the IGBT 4, and placing the IGBT4 in an active area to make part of the snubber current IS flow.  Consequently, the snubber current IS is shunt to the IGBT4 and capacitor 2 and the current IC which flows to the capacitor 2 is less than that in the absence of the IGBT4, and the voltage rise rate of the voltage of the capacitor 2, i.e., a voltage VT applied to the voltage-driven type thyristor 1 decreases.

Abstract: PURPOSE: To form a polymerized tough thin film having functionality on a substrate surface, by vaporizing a low-volatile or low-sublimable substance and by forming a polymerized thin film on th substrate simultaneously in the same plasma atomosphere.  
     CONSTITUTION: A substrate e.g. a high polymer film, metal piece, or glass, is placed in a plasma reaction vessel together with a low-volatile or low-sublimable substance for forming a polymerized film. The vessel is then evacuated by a vacuum pump, and the discharge is effected under a given pressure of 0.01W5 Torr and a given output of 5W400 W to give a plasma atmosphere with or without introduction of an atmospheric gas. Although the film is scarcely changed only by the vacuum, the plasma vaporizes the substance rapidly to form a polymerized thin film on the surfaces of the substrate and vessel.

Abstract: PURPOSE:To stabilize an air-fuel ratio by installing a gas-liquid separating plate at a position where an air pass providing a main air bleed and a fuel pass connecting a main jet with a main nozzle join and by providing a flow of two phases of the fuel and the air. CONSTITUTION:A bleed hole 9 is provided just under a main air bleed 6, and a rod shaped core part of a flange shaped gas-liquid separating plate 15 under said bleed hole is inserted into a main well 10 to permit the rise of a liquid level due to a interface phenomenon to be promoted. Fuel is suctioned into the main well 10 by negative pressure produced in a main nozzle 3, and is guided to the gas- liquid separating plate 15 to flow along the bottom in the main nozzle 3. Then, air suctioned from the main air bleed 6 passes through a upper part space in the nozzle 3, thereby allowing two phase flows obtained by separating gas and liquid completely to be produced. And, the fuel is atomized in a venturi part 2, and further a fuel flow in the nozzle 3 does not contain bubbles, so that an air-fuel ratio of a mixed gas is homogeneous.
