Title: Nonlinear active element and its production
Inventor: ITSUSHIKI KAIHEI
IPC: G09F9/30
Filed: 1992-05-06
Abstract: PURPOSE:To obviate the generation of an element breakdown and to enable driving at a low voltage by forming the metallic electrode to be provided on the extreme substrate side to a prescribed film thickness, thereby averting the degradation in a current-voltage characteristic. CONSTITUTION:This nonlinear active element is constituted by providing a lower electrode 2 on a substrate 1, forming a nonlinear resistance element 3 on the lower electrode 2 and forming an upper electrode 4 on the nonlinear resistance element 3. The lower electrode 2 provided on the extreme substrate side is constituted of any of Cr, Ni and NiCr alloys and is formed to >=50 to <=1000nm film thickness. An electric resistance increases and the current- voltage characteristic of the nonlinear active element is adversely affected if the film thickness of the metallic thin film to constitute the lower electrode 2 is thinner than 50nm. The failure in liquid crystal driving and the frequent generation of a trouble, such as disconnection are then resulted. A dielectric breakdown is liable to arise from the edge part of the nonlinear resistance element 3 and the lower electrode 2 as shown in a dielectric breakdown part A if the film thickness exceeds 1000nm.

Title: Finger-touching type coordinate input device
Inventor: YOSHIKAWA KAZUO
IPC: G06F3/041
Filed: 1983-06-23
Abstract: PURPOSE:To cancel the stray capacity and improve the sensitivity of a finger- touching type coordinate input device, by adding LC parallel resonators which resonate when no finger touches the finger-touching type coordinate input panel of the device. CONSTITUTION:When either one of X- and Y-directions is selected under a time shared condition by means of analog switches 8-1, 8-2, 9-1, and 9-2, it can be known from the output of an output terminal 13 that which position in this direction is touched with a finger. Since stray capacities exist in the analog switches and wiring and, therefore, the sensitivity of a touch sensor is lowered, LC parallel resonators 6 and 7 which resonate together with the above mentioned floating capacities when no finger touches a finger-touching type coordinate input panel 4 are provided in this invention. Because of the parallel resonators 6 and 7 which resonate to the frequency of a sine wave oscillator 1 including the stray capacities, decline in the sensitivity resulting from the existence of a stray capacity can be prevented.

Title: Controller for motor
Inventor: TAKEMURA YUTAKA
IPC: H02P7/00
Filed: 1988-05-11
Abstract: PURPOSE:To prevent a motor from burning by varying the speed of the motor to a speed set corresponding to each working step of a machine, and stopping the motor when a speed set signal is not zero but a low speed is continued for a predetermined period of time during operating. CONSTITUTION:An optimum speed is set by a selector 9 in a machine 5, one of switches 6-8 is closed, and speed signals set by speed setters 1-3 are input to a delay circuit 11, a differentiation circuit 12 and a zero detection circuit 13 through a switch 10. A driving circuit 15 slowly accelerates or decelerates a motor 5 by the output (f) of the circuit 11. A timer circuit 14 outputs a signal (i) of a level H by a trigger (g) from the differentiation circuit 12 for a predetermined period of time. When one step is finished and shifted to next step, next rotating speed is selected by the selector 9, and the differentiation circuit 12 newly outputs a trigger signal (g) of a level H. If the step is not finished even after a predetermined period of time is elapsed, it is judged as the trouble of the machine 5 to open the switch 10. Thus, it can prevent the motor 4 from burning.

Abstract: PURPOSE:To prevent invasion of a foreign matter from a clearance between a bearing and a shaft while obtaining expansion/contraction of bellows. CONSTITUTION:A receiving/delivering apparatus has a shaft 45 with a wafer receiving plate 45 slidably supported by a bearing 44 at a wafer holder 41 and bellows 48 expandably and contractably mounted between a lower surface of the holder 41 and an intermediate part of the bearing 45 outside the shaft 45, and comprises a bent passage 51 interposed with traps 54, 55, 56 on the way and so opened at the holder 41 as to communicate an outer periphery of the holder 41 with a hollow part of the bellows 48.

Accordingly, invasion of a foreign manner into the hollow part of the bellows 48 can be prevented, and damage of the bellows 48 can be prevented. The expansion and contraction of the bellows 48 are obtained by introducing and discharging gas via the passage 51.

Filed: 1988-05-11
Abstract: PURPOSE:To increase the etching ratio between an etching part and a non- etching part even for an object having low vapor pressure at room temperature and to perform fine machining, by removing a reformed part under treatment by etching. CONSTITUTION:An oxide film 2 and a Cu thin film 3 are formed on the surface of a silicon substrate 1. In this semiconductor substrate, at first, a part other than non-etched regions 5 in the Cu thin film 3 is masked with a mask 4 of an organic applied film such as photoresist or an inorganic thin film such as an oxide film. Then, plasma treatment is performed in CCl4 gas, and the Cu thin film 3 in the non-etched regions 5 is reformed into CuCl2 which is a chloride compound. The vapor pressure of said CuCl2 is high at high temperature but low at room temperature. Therefore, the CuCl2 is not sublimated in the normal sate. Then, the CuCl2 is heated in a short time by the projection of a laser beam and the like, resistance heating or the like. Thus, the CuCl2 is sublimated. In this way, accurate, fine machining characterized by a small pattern shift can be performed in a short time.

Title: Drain discharge device in oil filter unit
Inventor: FUJISHIMA TOSHIKAZU
IPC: B01D29/94
Filed: 1978-09-19
Abstract: PURPOSE: To automate drain discharge by a mechanism wherein differential pressure is detected between filter inlet and outlet, whose result is employed to cause the liquid pressure of either filter inlet or outlet to open the main valve to discharge drain outside.  
     CONSTITUTION: When drain concentration in filter chamber increases, self-cleaning function decreases, and the pressure loss at filter outlet and inlet increases and the pressure difference between them causes the auxiliary valve member 11 to be released from the valve seat 8. Part of oil at the filter inlet side passes through oil chamber 4 and enters the oil chamber 15. The main valve member 18 is released from the main valve seat 16. High concentration drain in the filter chamber is discharged through drain chamber 12 to drain tank. This recovers self-cleaning function, the auxiliary valve member 11 closes, oil in the oil chamber 15 is returned through orifice 19 to the oil tank, the main valve member 18 closes, and drain discharge to the outside of the system is stopped.

Abstract: PURPOSE:To always surely execute the reset by constituting this circuit so that the power-on reset in applied at the time point when both a first and a second power source lines rise, whichever rises first. CONSTITUTION:When a second power supply voltage Vcc2 is supplied to a first power supply voltage input terminal (a) and a second power supply voltage input terminal (b), a power-on resetting circuit 1 sets an output voltage Vo to an 'H' level after a prescribed time (T).
