Title: Sawtooth wave generating circuit
Inventor: IWAKURA MITSUO
IPC: H03K4/50
Filed: 1985-03-05
Abstract: PURPOSE:To realize high speed operation stably by using one set of field effect transistors (TRs) and one set of TRs and providing a circuit being the combina tion of the 2nd field effect TR and the 2nd TR being an emitter follower be tween the source and power supply of a source follower so as to eliminate the need for a negative feedback loop. CONSTITUTION:The characteristics of the 1st field effect TRs 1, 2 and the 1st TRs 5, 6 are arranged so that the absolute value of the gate-source voltage of the TRs 1, 2 being the source follower and the base-emitter voltage of the 1st TRs 5, 6 being the emitter follower is made equal. Let the gate-source voltage of the TRs 1, 2 be VGS1, VGS2 respectively and let the base-emitter voltage of the TRs 5, 6 be VBE5, VBE6 respectively, since the TRs 1, 2 and 5, 6 are arranged for each characteristic, the relation of VGS1=VGS2 and VBE5=VBE6 and DELTAV=0 is obtained. That is, the offset voltage DELTAV between the gate of the field effect TR 1 and an output terminal 62 is zero. Thus, no negative feedback path is required.

Title: Data recording and reproducing device and burst position conversion factor determining method for the device
Inventor: SHIBATA SATOSHI
IPC: G11B5/55
Filed: 1996-02-29
Abstract: PROBLEM TO BE SOLVED: To easily calculate the true value of a burst position conversion factor compatible to a head to be used. SOLUTION: The first positional information expressing the deviation of the position of a head 2 from a track center is calculated based on the pair of one side (the pair of burst data A, B) among two pairs of burst data recorded on a disk 1 and the head 2 is positioned at an arbitrary target position in a burst output detectable hand where both of the two pairs of burst data are detectable based on the first positional information. Then, a second positional information is calculated based on the pair of another side and a CPU 11 repeats a processing adjusting a burst conversion factor K until the difference between the first and second positional information becomes no larger than a prescribed value so that the discontinuity between the first and the second positional information extinguished to store the result in a RAM 15. This operation is repeated for all heads 2 of the device.

Title: Hall element and magnetic head
Inventor: MATSUDAIRA YASUHIKO
IPC: G11B5/37
Filed: 1988-02-26
Abstract: PURPOSE:To fulfil two functions; electromagnetic conversion and waveform shaping simultaneously by using one Hall element, by causing two kinds of substances having different Fermi levels to be formed into a two-layer structure, thereby forming a potential gradient or barrier between the two layers. CONSTITUTION:A two-layer structure consisting of layers 10 and 12 having low and high Fermi levels is formed. If a current I flows in the layer 10 of low Fermi level, electrons move to the reverse direction. When a magnetic field B is impressed, the electrons are put aside by Lorentz's force. However, when the strength of the magnetic field B is less than the prescribed value, a potential V gradient or barrier obtained by the foregoing two-layer structure prevents electrons from moving from layer 10 to layer 12 and no electromotive force takes place. When its strength of the magnetic field B becomes more than the prescribed value, the electrons move from layer 10 to layer 12 and are stored in an electrode 20. Thus, electric polarization is formed between electrodes 18 and 20 and then, Hall electromotive force EH takes place.

Title: Air conditioner
Inventor: TAKAMARU KOICHI
IPC: F25B49/02
Filed: 1989-02-23
Abstract: PURPOSE:To simplify a circuit configuration by forcibly driving a compressor for a fixed time when power is thrown in, comparing a detected electric current value with a reference value, and a tube temperature of an indoor side heat exchanger after a fixed time's lapse with the operation contents of an air conditioner and then detecting a failure. CONSTITUTION:A microcomputer 15 for an indoor unit 1 turns on a power supply relay 6 when a power supply switch is turned on, drives a compressor 9 of an outdoor unit 2 forcibly for a fixed time, compares its total electric current value with a reference value, and devices the presence of any operational failure. Moreover, it compares a temperature of tubes for an indoor side heat exchanger, which is detected by an inner tube temperature sensor 4, with the operation contents of an air conditioner, and decides the failure based on whether or not the temperature of the tubes is equivalent to the detected operation contents. It is, therefore, possible to eliminate the need for a receiving/ transmitting circuit which receives and transmits a signal from or to an indoor unit 1 and an outdoor unit, and an outdoor unit micro computer, thereby simplifying the configuration of a failure diagnosis circuit.

When difference between old image data and the new one is smaller than a setting value, noise is judged and a value smaller than the difference is added by an adder 6 so as to restrict an output signal. Or when a difference signal becomes more than a certain peak level, movement is judged to be large and a field/frame storing mode changeover circuit 9 changeover-controls a drive circuit 8 so as to change over the operation mode of the CCD element 1 from a standard frame storing mode to a field storing mode.
