Title: Formation of titanium oxide film
Inventor: NAKAI HIDEMI
IPC: C03C17/245
Filed: 1988-06-30
Abstract: PURPOSE:To form a titanium oxide film on the surface of a base material by initiating arc discharge in a chamber in a state where metallic titanium is used as a cathode and a base material is disposed in a position opposite to this cathode. CONSTITUTION:Arc discharge is initiated in a vapor deposition source of metallic titanium 4 placed on a cathode 3. Since an arc spot formed on the metallic- titanium surface by the above procedure becomes the part of highest discharge current density and, as a result, Joule's heat is generated and the temp. of this spot becomes extremely high and the metallic titanium 4 is evaporated, an extremely high film-forming velocity can be attained. In addition, the arc spot moves around on the metallic-titanium surface at high speed, by which the surface of the metallic titanium becomes continuously renewed surface and a titanium oxide film can be formed at high speed in a large area in an evacuated chamber.

Title: Operational amplifier
Inventor: AOKI TETSUO
IPC: H03F1/00
Filed: 1987-07-02
Abstract: PURPOSE:To reduce the number of operational amplifiers in a device necessitating many sample hold-circuits by providing the operational amplifier itself with a master-slave type sample-hold circuit. CONSTITUTION:A differential amplification stage 1 accomplishes the function of a master side output buffer for an input signal, and an electronic switch 2, installed between the differential amplification stage 1 and an output stage 3, accomplishes the function of an analog switch. Then, because a capacitor CP for phase compensation accomplishes the function of a data hold capacitor according to ON/OFF of the electronic switch 2, it comes to be the master-slave type sample-hold circuit as a whole. Thus, since the master-slave type sample- hold circuit can be constituted within one operational amplifier, the circuit can be simplified, and the power consumption of the circuit can be reduced.

Filed: 1985-07-24
Abstract: PURPOSE:To detect an display even a one-shot pulse and a very short pulse generated intermittently by displaying the binary state of an output voltage of a buffer amplifier circuit onto the 1st display circuit and using the output of the buffer amplifier so as to display in binary the output state of a bistable multivibrator circuit on the 2nd display circuit. CONSTITUTION:A logic voltage inputted from an input terminal 1 is subjected to buffer amplifier by an inverter I1. Then an output voltage of the inverter I1 is inputted to a display device 3 and the output voltage of the inverter I1 is displayed in binary value. Further, on output voltage of the inverter I1 is inputted to the 2nd inverter I2, the inverted voltage is displayed on the display device 3 comprising a transistor (TR)Q2 and an LED L2. Then the output voltage of the inverter I2 drives the bistable multivibrator circuit F1 and the logic state of output terminals Q, Q' is inverted by transiting the voltage at an input terminal CK of a flip-flop F1 from logical 1 to logical 0. The measuring personnel detects a short pulse caused at the input terminal 1 depending on the change in the lighting state of the LED by displaying the state of the outputs Q, Q' onto LEDs L3, L4.

Title: Printing method
Inventor: ONCHI MINORU
IPC: G06F3/12
Filed: 1989-06-27
Abstract: PURPOSE:To optionally and instantaneously stop temporarily and restart a printing operation by stopping temporarily the printing operation with input of a prescribed 1st control code and then restarting the printing operation with input of a 2nd control code obtained at the end of working of a print subject. CONSTITUTION:The information on a printing state sensor 3 is received via a monitor means 2 with detection of a control code which requests the temporary stop of a printing operation. Then the output of the print data is stopped with an instruction given to a drive means 5 at a print state (e.g., a line feed mode, etc.) when the printing operation can be stopped if a printing mode is kept. Thus the means 5 stops the drive of a print unit 6 and the printing operation is temporarily stopped. Meanwhile the stop request is neglected in a print stop mode. If a control code is received for request of the restart of the printing operation, the restart request is neglected if the print mode is kept. While an instruction is given to the means 5 to restart the output of the print data and to start the drive of the unit 6 in a print stop mode. Thus the printing operation is restarted. As a result, the print temporary stop and restart requests can be instantaneously processed.

Title: Level detecting circuit
Inventor: OGAWA ATSUSHI
IPC: G01R19/12
Filed: 1981-10-15
Abstract: PURPOSE:To obtain a detecting circuit whose dynamic characteristics is improved and is suitable for the formation of an integrated circuit, by a method wherein the rise time constant of an output signal level is caused to change corresponding to the change in an input signal level. CONSTITUTION:A detecting circuit 22 has a half-wave rectifying characteristic and a characteristic in which a relation of an input signal voltage V1 to an output signal voltage V0 is brought to a non-rectilinear manner. A feedback circuit  23 compares the input signal voltage V1 with the output signal voltage V0 of the detecting circuit 22, and performs a correction such that the input and output characteristic of the detecting circuit 22 is brought to a rectilinear manner. If the input signal voltage V1, supplied to an input terminal 21, becomes high, the output signal voltage V0 of the detecting circuit 22 tries to increase, but the  higher the input signal voltage V1 is, the more rapidly a capacitor 24 is charged with a high current through the action of the feedback circuit 23. This permits rising of the output signal voltage V0 for a short time constant in correspondence to the input signal voltage V1.

Abstract: PURPOSE:To reduce a driving power for a compressor in order to improve fuel consumption by idling one cylinder of two-cylinder compressor when the thermal load in the car is decreased and by reducing the flow rate of air supplied into the car. CONSTITUTION:When the thermal load in a car is decreased, a thermosensor 12 detecting the temperature of suction air, outputs its signal via a controller 11 to a solenoid control valve 5 to close itself as well as to a fan 10 to reduce the flow rate thereof. Accordingly, the quantity of refrigerant sucked into a varaible capacity compressor 4 is decreased by half so that one of two cylinders is idled, on account of which the circulation quantity of rerigerant may be reduced by half so that the transit air through a cooler 9 is lessened. Both the cooling capacity and driving power for the compressor may be thus reduced.
