Title: Heat transfer surface and its preparation
Inventor: FUJII MASAO
IPC: F28F7/00
Filed: 1978-08-22
Abstract: PURPOSE: To obtain this heat transfer surface with excellent heat transfer characteristics, by forming metallic film shells by accumulating particles in inorganic matter on the heat transfer surface, by making up a metallic film and by removing the particles.  
     CONSTITUTION: Particles 7 with arbitrary shapes and a heat transfer substrate 2 are immersed in plating liquid under conditions that the particles are beforehand accumulated on the substrate 2 in suitable layer numbers, thus building up a metallic film 8. Inorganic matter 7 is removed mechanically, thermally or chemically, and this porous heat transfer surface by metallic film shells 9 is formed. Consequently, a large number of cavities can be made up by the metallic film shells 9 because the particles 7 accumulated on the heat transfer surface are eliminated, thus obtaining large heat transfer area, then easily gaining this heat transfer surface with excellent heat transfer characteristics.

Title: Coin feeding device
Inventor: GOMI YOSHIAKI
IPC: G07D9/00
Filed: 1998-04-14
Abstract: PROBLEM TO BE SOLVED: To stably and separately carry coins by surely resolving the overlap state of coins by the returning force of a separation roller even in the case that overlapping coins are caught between a carrying belt and the separation roller. SOLUTION: If coins C enter between a carrying belt 1 and a separation roll 2 while overlapping, the carrying belt 1 is deformed in the escape direction along belt escape parts 5d and 5e of a belt guide member 5 to form a space equal to or larger than a passage space G though a force in the belt pressing direction is generated, and therefore, a force in the sending direction to a coin C3 is not increased. The passage space G is kept by a projecting space forming part 5a extended along the coin carrying direction, and two or more coins cannot pass simultaneously, and the contact area to the carrying belt 1 of the coin C3 to be returned by the separation roller 2 is reduced to an extent approximating the width of the space forming part 5a to reduce the force in the sending direction.  By this condition, the overlap state of coins is resolved by the returning force of the separation roller 2, and coins are surely and separately carried.

IPC: H03B23/00
Filed: 1978-08-28
Abstract: PURPOSE:To prevent the fluctuation of the oscillation frequency for the sweep oscillation device used for the spectrum analyzer or the like through the feedback control, thus obtaining the steady sweep output. CONSTITUTION:An addition is given at adder circuit S to output (a) and (f) of ramp voltage generator R and voltage holding circuit H, and sweep oscillator O is controlled. Then the output of oscillator O and the output of reference oscillator K are applied to mixer M and then to pulse generator P via low pass filter L. Here if filter L transmits the output of a fixed frequency, pulse (c) is applied to time- voltage converter T. Pulse (b) generated for the pause period of generator R is applied to converter T to deliver voltage (d) corresponding to the time from the rise of the ramp voltage to pulse (c) to gate G for sampling. Thus pulse (e) is supplied to circuit H. With increase of output voltage (a) of generator R, the time (t) from the rear edge of pulse (b) to pulse (c) decreases. And accordingly output volgage V of converter T decreases to reduce voltage (a), thus preventing the fluctuation of the oscillation frequency.

IPC: H03G3/20
Filed: 1992-04-23
Abstract: PURPOSE:To prevent the deterioration in a voltage standing wave ratio of a high frequency amplifier circuit even when gain control of a high frequency signal is implemented in response to the quantity of a receiver input by selecting a signal transmission circuit connecting to an output of the high frequency amplifier circuit. CONSTITUTION:A signal from an input terminal 1 is amplified by a high frequency amplifier circuit 2 and a level of its output signal is detected by an output detection circuit 8. When the level of the output signal does not exceed a prescribed level, switch circuits 3, 7 are used to connect a signal transmission circuit B comprising an output matching circuit 6 to the amplifier circuit 2 and an output terminal 9 thereby obtaining a desired gain. Furthermore, when the level of the output signal exceeds a prescribed level, the switch circuits 3, 7 are used to give an output signal of the amplifier circuit 2 to a signal transmission circuit A comprising an attenuator 4 and the output matching circuit 5 thereby decreasing the level of the output signal. As a result, the high frequency automatic gain control circuit is obtained in which the level of the output signal of the amplifier circuit 2 is controlled to be a prescribed level without deteriorating the voltage standing wave ratio of the high frequency amplifier circuit 2.
