Title: Variable frequency oscillator
Inventor: YAMAMOTO YUUZOU
IPC: H03L1/02
Filed: 1980-04-16
Abstract: PURPOSE:To stabilize the temperature for a variable frequency oscillator, by securing the dependence of bias upon the temperature for a transistor which supplies the control voltage to a variable capacity diode and then cancelling the temperature characteristics of both the transistor bias and the variable capacity diode. CONSTITUTION:The oscillating circuit 2 consists of the variable capacity diode VC, capacitor C1 and inductance L. The emitter voltage of the transistor 3 is applied to the diode VC, and the phase error voltage of the PLL loop is supplied to the base electrode of the diode VC from the input terminal 4. When the collector cut-off current ICO of the transistor 3 increases by the temperature, the emitter current IE increases to work to reduce the capacity value of the diode VC. Thus the temperature dependence is offset for a variable capacity diode that is liable to increase its capacity value by an increase of temperature.

Title: Recording device preventing developer carrier from floating
Inventor: OWADA SUSUMU
IPC: G03G15/08
Filed: 1986-03-08
Abstract: PURPOSE:To stably hold a photosensitive body and a developer carrier at a constant interval by arranging the intermediate part of an abutting roller below the center of the image carrier. CONSTITUTION:An abutting roller 40 is provided rotatably at both end parts of the shaft 13a of a developing roller 13 and pressed against the photosensitive drum 10 by the pressing member 42 of an attaching/detaching device 41 fitted to a machine frame 39, so that the developing roller 13 is arranged nearby the photosensitive drum 10 in parallel at a constant interval.

Title: Capacity detection device for vehicular battery
Inventor: TASHIRO HIROSHI
IPC: G01R31/36
Filed: 1994-03-23
Abstract: PURPOSE:To detect the accurate capacity of a battery during the travel of a vehicle by finding a difference between voltage at the time of generating operation with the prescribed current value in the vibration damping control of an internal combustion engine, and voltage detected during generating operation immediately before and after the control. CONSTITUTION:When an ignition switch SW7 is turned on, an engine control unit(ECU) 6 outputs a motor drive instruction to an inverter 2, thereby causing constant field current to flow. At the same time, the duty ratio of an inverter 2 is controlled in the prescribed control mode to cause starting current to flow to a stater 1, thereby starting an internal combustion engine 10. When the speed of the engine 10 reaches, for example, 200rpm after a start and beings continuous combustion, the loaded torque of the starter 1 decreases and the starting current is reduced. Thus, voltage is detected at a step 5, when the starting current drops to the prescribed value and battery capacity is calculated on the basis of the detected voltage value at a step 6. According to this construction, the initial capacity of a battery 3 can be calculated easily and quickly.

Abstract: PURPOSE:To attain high speed and stable data transmission by setting the difference frequency f3 of a mark frequency f1 and a space frequency f2 and the baud frequency of a second channel to the relation of n:m in a transmission side and extracting f1 and f2 from an FSK demodulation circuit and m- multiplying and n-dividing both frequencies in a reception side. CONSTITUTION:A frequency generation circuit 1 on the transmission side has a liquid crystal oscillator. With frequency-dividing it, the difference frequency of the frequencies f1 and f2, and f3 are set to the relation of 7:240. An addition circuit 4 adds the transmission signals of transmission circuits 2 and 3 and transmits them to a transmission line 10. A receiver 7 has the FSD demodulation circuit and it outputs f1 and f2 with digital data. A multiplication/frequency- devision circuit 9 outputs the frequency f3 by multiplying the difference frequency of f1 and f2 by 240 and frequency-dividing it by seven. The baud clock required for the action of the receiver 8 is supplied from the multiplication/ frequency-division circuit 9.

Filed: 1990-03-02
Abstract: PURPOSE:To form a dense and uniform composite metal oxide film at a high speed by discretely controlling conditions, such as evaporation temp., of raw material metals, flow rate of gases and temp. for mixing with reactive gases. CONSTITUTION:Raw materials 4, 10 are put into boats 3, 9 and are evaporated by heating to about 130 to 200 deg.C by heaters 7, 11. The evaporated raw materials are transported up to a mixing section S2 where the vapors are mixed with the reactive gases contg. O2. The atmosphere temp. of the mixing section S2 is controlled to about 150 to 200 deg.C to prevent the recrystallization of the evaporated metals and the nucleous formation by a vapor reaction. The sufficiently mixed gases are introduced to a reaction section S3 where the atmosphere is heated to about 500 to 1000 deg.C by a heater 13 to generate a decomposition and oxidation reaction and to form the nuclei on a substrate 14. The crystals are grown with the nuclei as base points. The composite oxide film 14a of the metals is thus formed.
