Abstract: PURPOSE:To adopt a high power supply voltage for a integrated circuit device and to avoid the effect of power supply voltage fluctuation by providing a 2nd load resistor in parallel with a drive FET(field-effect transistor(TR)). CONSTITUTION:A 1st load resistor 11 is connected in series with a source and a drain of a drive FET 1 being an n-channel enhancement PN junction FET to form an E/R DCFL circuit (direct coupled FET logic circuit).

Furthermore, a power supply voltage is selected to be within a permissible voltage changing rate to avoid injection of positive holes being a problem in the FET.

Inventor: MORIMOTO KAZUO
IPC: G01N29/24
Filed: 1983-03-04
Abstract: PURPOSE:To reduce blind sectors by improving the shape and arrangement of transmitting coils and receiving coils. CONSTITUTION:An electromagnetic sound transducer in which transmitting coils 4 are placed in the clearance between a central magnetic pole 3a and outer peripheral pole 3b of a coil 1 and two receiving coils 51, 52 are arranged concentrically in the clearance is placed oppositely to an object to be tested. When a high-frequency current is applied to the transmitting coil 4, an eddy current is generated, and a ultrasonic wave that propagates in the direction perpendicular to the surface of the object to be tested is generated. At this time, the high frequency current applied to the transmitting coil 4 is induced by the coils 51, 52 for split reception, and generates a voltage. As the coils 51, 52 for split reception are reverse in the direction of winding and connected in series, the induced voltage is canceled. Consequently, the induced voltage is not generated in the terminals of the receiving coils 51, 52 and blind sectors are elminated.

Abstract: PURPOSE:To enable the inversion of heat radiation and endotherm by applying a surface treatment, in which the values of a sunshine absorption rate and an infrared radiation rate are different according to a position, to a heat radiation surface, and moving the heat radiation surface according to temperature. CONSTITUTION:A heat radiation surface 1 which is to become a controlled surface has a belt state, and is moved by the rotation of a gear 2. The surface of the surface 1 is dividingly painted obliquely using the surface treatment in which the (epsilon-alpha) value is positive (e.g., white painting) and that in which the (epsilon-alpha) value is negative (e.g., black painting) where epsilon means an infrared radiation rate and alpha means a sunshine absorption rate. This makes the alpha and epsilonvalue of the surface in the range exposed in the surface to change to space 3 by the rotation of the gear 2. Since a heat radiation effect is higher when the (epsilon-alpha) value is positive and larger, and when the temperature of the surface 1 is high by the exothermicity of an equipment 5, the surface 1 is set to the position where the (epsilon-alpha) value is large, and when the temperature of the surface 1 lowers with the equipment 5 off, the surface 1 moves, the (epsilon-alpha) value nears the negative value, and endotherm is conducted.
