Title: Power switch circuit
Inventor: NUNOKAWA YASUHIRO
IPC: H03K17/16
Filed: 1988-10-31
Abstract: PURPOSE:To reduce noise in switching by applying switching control on a power MOSFET by the smoothing voltage of a pulse signal whose pulse duty is increased according to the lapse of time, CONSTITUTION:An input signal to an input terminal IN is inverted by an inverter circuit N1, and is supplied to the input on one side of an AND gate circuit G2. The output pulse of a pulse duty generation circuit PDG is supplied to the input on the other side of the circuit G2. The output signal of the circuit G2 is supplied to a smoothing circuit consisting of a diode D2, a resistor R2, and a capacitor CG via a level conversion circuit LC2 in which a booster voltage exceeding potential (Vcc+Vth) is set as an operating voltage. At the circuit LC2, an output signal with a phase negative to that of the input signal is formed, and the diode D2 forms a smoothing current to discharge the gate capacitor CG. In such a way, the smoothing circuit functions at the time of switching the power MOSFET Q1 from an ON-state to an OFF-state.

Filed: 1985-12-11
Abstract: PURPOSE:To improve a using rate by preparing plural operation guidances in plural languages to an automatic teller machine and allowing operators to select a specific one prior to operation. CONSTITUTION:Besides a general Japanese guidance message 4, the necessary number of guidances written in other languages are displayed below the Japanese one as the display contents of the guidance display part 2 of the automatic teller machine (ATM) 1. For instance, if it is the guidance in English 5, the operator presses a tenkey 7. If other languages 6 are wanted, a key 8 among the tenkey 7 is pressed to selectively display. Thus the operator selects the prescribed transaction through a transaction selection screen, and afterwards he can keep transactions in the same manner as according to the Japanese guidance.

Abstract: PURPOSE:To elevate the temperatures of the whole semiconductor wafers uniformly, and to enable equal oxidation and diffusion treatment by installing heaters to the center and outer circumference of a core tube while arranging a plurality of the semiconductor wafers in the core tube, faced oppositely to the inner wall of the core tube in the periphery of the heater at the center. CONSTITUTION:Semiconductor wafers 17 held to a port 15 are heated by two heaters 12, 13 mounted to the center and outer circumference of a core tube 11. Distances up to the heaters 12, 13 from central sections and distances up to the heaters 12, 13 from outer edge sections are equalized approximately as shown in d11, d21, d12, d22 in each semiconductor wafer 17 at that time. The distance d21 from the central section is made slightly longer than the distance d22 from the outer edge section to the heater 13 on the outer circumference, but the distance d11 and the distance d12 are reversed to the heater 12 at the center and the distance d11 from the central section is made slightly shorter than the distance d12 from the outer edge section, and the slight difference of the distances from the central section and the outer edge section is offset by the two heaters 12, 13. Accordingly, the central sections and outer edge sections of the semiconductor wafers 17 are positioned at distances equal to the heaters 12, 13, thus uniformly elevating the temperature of the whole semiconductor wafers 17.
