Title: Remote power control circuit
Inventor: GOTO TOSHIAKI
IPC: G05F1/66
Filed: 1988-09-06
Abstract: PURPOSE:To protect power MOS FET and a resonance circuit from a short state due to a fault of load and misoperation by transmitting the control signal of an amplitude equivalent to the voltage drop of a diode and the voltage of a variable output power to a discriminator. CONSTITUTION:The output of a signal generator 1 is impressed between a gate 9 and a source 8, and power MOS FET 3 is controlled. Power drop occurs in a coil 12, and a signal voltage is superimposed on a battery voltage in a signal line by permitting an excess current to flow in a capacitor 10. The reception discriminator 5 reads the difference of the pulse internal of the superimposed signal or the number of the pulses within a prescribed time, gives the control signal to a controller 6, and supplies DC power to a load 7. Consequently a smoothing capacitor 15 corrects the resonance frequency by the wiring inductance 13 between a battery 2 and the load 7. Thus, a loss can be reduced and malfunction hardly occurs.

Title: Reticle and its production
Inventor: HAYASHI KENJI
IPC: G03B13/24
Filed: 1983-11-26
Abstract: PURPOSE:To produce reticles simply and economically by working a pyramid- like regular uneven relief, electroplating the relief surface to form a lens surface and forming many fine recessed parts on the lens to transfer the electroplating surface to an optical element. CONSTITUTION:Nickel is plated on the mechanically worked pyramid-like relief to turn the pyramids to a shape arraying smooth semisperical surfaces regulately. When the arraying pitches of the relief is 20mu or less and an angle formed by the fine lens-like shapes turned from the pyramids by the nickel plating with the bottom is 15 deg. or less, required brightness and focusing are obtained. Since the fine lens group has regularity due to the mechanical working, diffraction phenomenon is generated, an interference color is generated on the reticle and a out-of-focus image is made like a ring. Since the extremely fine recessed parts are formed on the plated surface, coloring due to the diffraction phenomenon and the ring formation can be removed and a particle-less and bright reticle having high focusing property is obtained.

Title: Magnetic recording and reproducing device
Inventor: HAMADA MASAHARU
IPC: G11B5/54
Filed: 1982-12-22
Abstract: PURPOSE:To smooth the traveling of a magnetic tape in a recording and reproducing device having a full width erasing head by moving the full width erasing head to the position where it does not contact with the magnetic tape except in a recording mode. CONSTITUTION:When a power source is supplied to a VTR, a solenoid driving circuit 17 is so constituted as to de-energize a solenoid 5 by the stop mode signal from an operating part only when the signal of a recording mode comes in said circuit. An arm 8 is therefore rotated by the excitation of the solenoid and a full width erasing head 3 does not contact with the tape 1 any more. When a shuttle mode is set, the solenoid is not de-energized and therefore the tape 1 travels without contacting with the head 3. When a recording mode is set, the circuit 17 operates to de-energize the solenoid 5, and the arm 8 is rotated by a tension spring 14, then the V-groove 15a of a block 15 contacts with a stopper pin 13, thereby stopping the arm 8. The tape 1 is wound at a prescribed angle on the head 3 in this stage and the recorded signal is erased.

Title: Air conditioner used for heating and cooling room
Inventor: ARAKAWA MASASHI
IPC: F24F11/02
Filed: 1984-10-26
Abstract: PURPOSE:To detect adherence of frost to a heat exchanger with high accuracy but without undergoing influences of the flow of external air and temperature so as to enable selecting an appropriate defrosting period of time, by carrying out the control of the air conditioner in compliance with a temperature difference between the evaporation temperature corresponding to the evaporating pressure of the indoor heat exchanger and the external temperature, and a set value set as a function of the external temperature. CONSTITUTION:At the time of a heating operation, from the suction pressure of a compressor 5 sensed by a pressure sensor 10, the evaporation pressure of an outdoor heat exchanger 7 corresponding to the above suction pressure is found, and the evaportion temperature is determined readily from the evaporation pressure. The temperature difference (t-t0 deg.C) between the evaporation temperature t0 deg.C and the external air temperature t deg.C sensed by a temperature sensor is indicated as a function of the external air temperature t deg.C to obtain a line A of a set value at which frosting of the outdoor heat exchanger 7 is to be warned and a line B of a set value at which a defrosting operation is to be started. Accordingly, by carrying out the defrosting operation based on these lines, appropriate defrosting can be performed with high accuracy.

Title: Ultrasonic boring method and device
Inventor: IIHASHI SHINSUKE
IPC: B24B1/04
Filed: 1996-08-26
Abstract: PROBLEM TO BE SOLVED: To use a cutting tool having a small diameter and drill a hole of small diameter by vibrating the cutting tool at a boring process so as to give a circular motion within a plane vertical to the lengthwise direction of the tool. SOLUTION: At a machining process, a cutting tool 8 is vibrated so as to give a circular motion within a plane vertical to the lengthwise direction thereof. When the vibration direction of a vibrator 1 and a tool direction are not in complete agreement with each other, the tool 8 laterally resonates at a certain vibration frequency. At this cutting process, the application of a shock in a tool direction is not required. As a result, the use of hard but fragile material such as high-speed steel and cemented steel is not needed. Consequently, a spring material having higher toughness than the high-speed steel or cemented steel can be used as a tool material. Also, the use of the spring material allows the manufacture of a fine cutting tool 8 having a minimum diameter approximately equal to 0.05mm, and the available tool 8 has high resistance against a bending force and a breakage.  Furthermore, a hole of diameter equal to or less than 0.02mm can be drilled by using the tool 8.
