Filed: 1980-05-20
Abstract: PURPOSE: To avoid uneven etching by placing a wafer in close contact with a wafer installation surface having areas where potential is dropped by high frequency discharge and areas exhibiting the potential differing from that.  
     CONSTITUTION: In a plasma etching device, a substrate made by forming rectangular striplike electrodes 14 constituting electrode pairs at about 1mm intervals by a printed wiring method on an insulating backing material 13 and coating an insulating film 15 thereon is mounted on an electrode (cathode) 1. The electrodes 17 on one side of the electrodes 14 are connected to the electrode 1. Hence, areas which receive cathode drop voltage of several hundred voltages generated in the cathode 1 during high frequency discharge produced on the wafer installation surface on the electrode 1, that is, on the surface of the insulating film 15, according to the electrode 17 patterns. Since the other potential is applied to the electrodes 18 on the other side of the electrodes 14, the areas exhibiting the different potential are produced on the film 15 surface according to the electrode 18 patterns. Then, an Si wafer 3 is placed on the film 15 surface in close contact therewith by the electrical attraction force generated thereon. When the discharge is stopped, the wafer 3 is released from the close contact.

IPC: H03K19/0175
Filed: 1994-03-10
Abstract: PURPOSE:To provide the semiconductor integrated circuit with an output circuit capable of forming the output level according to the relatively low power supply voltage while keeping the high integration processing and high speed processing. CONSTITUTION:The output signal is obtained from the external terminal by switch-controlling the N-channel MOSFETs Q1 and Q2 connected in serial with the relatively low power supply voltage and the ground potential of the circuit. A driving signal to be supplied to the gate of the output MOSFET at the power supply voltage side is formed by a CMOS circuit consisting of MOSFETs Q3 and Q4. The operation voltage is boosted voltage using a bootstrap circuit. Thus, the high integration processing and the high speed processing are realized by using the N-channel MOSFET and the gate voltage of the output MOSFET Q1 which forms the output level at the power supply voltage side can be made high voltage corresponding to the boosted voltage. Thus, the output level can be made the one corresponding to the power supply voltage.

Abstract: PURPOSE:To perform smooth changeover from control based on a voltage to control based on slip frequency, by providing such a voltage control loop that the characteristic of a slip frequency control amplifier changes depending on the fluctuation in the voltage of power. CONSTITUTION:The output of a torque setting unit 1 is converted into a current instruction and a slip frequency instruction by converters 2, 9.

The outputs of the amplifier 5 and a voltage detector 6 are conducted through a subtracter 7 and an amplifier 8 of a voltage control loop. The output of a slip frequency control amplifier 10 is added to the slip frequency intruction by an adder 11. The voltage and frequency of an inverter 16 are thus controlled. Since the characteristics of the slip frequency control amplifier 10 changes depending on the fluctuation in the voltage of power, the running characteristic of an electric vehicle is optimized.

IPC: G03B27/62
Filed: 1979-05-31
Abstract: PURPOSE:To remove the black belts at the boundary of external information and original by removing the residual electrostatic charge occuring in the operation of shutter before or after the optical projection of external information in the method of recording the external information and original as composite images. CONSTITUTION:The opening and closing operations of the shutter which opens and closes the optical path for the opticl images of the original are controlled by the leading- and trailing-end detecting signals S1, S2 of the original, and the times T1, T2 at which the shutter is half open exist in the shutter operations. There is a deviation in the radiating position of the original and external information on the photoreceptor. In order to remove the residual electrostatic charge on the photoreceptor owing to the above two points, the external information luminance signal is corrected like composite luminance signal by the opening and closing time correcting signals V1, V2 and position deviation correcting signals U1, U2 made from the delay change-over signals S1', S2' and T1, T2. As a result of the above, the above- mentioned residual electrostatic charge enables the prevention of the production of any black belt at the boundary between the external information and the original.
