Filed: 1989-02-03
Abstract: PURPOSE:To improve the controllability by image-taking the state of combustion by a TV camera and obtaining binary coded picture images by binary-coding and retrieving a coincidental pattern from flame shape patterns that are beforehand set up to judge the state of combustion so as to control supply means and transfer means. CONSTITUTION:The image of combustion in a combustion furnace 1 is picked up by an industrial camera 9 and the photo-images are inputted to a treatment device 14. The pictures that are input to the treatment device 14 are binary- coded to provide binary code photo-images, and the present state of combustion is judged by retrieving a coincidental pattern from the flame shape patterns that are beforehand stored in a memory. And, from the state of combustion a subtle change in the state of combustion is grasped to control the speeds of a stoker 5 and pusher 4. With this constitution the controllability of the incinerator is raised.

Title: Dc-dc convertor
Inventor: HAYASHI KATSUNORI
IPC: H02M3/155
Filed: 1980-03-04
Abstract: PURPOSE:To reduce the collector dissipation in a transistor, by mounting a transformer between a transistor and an output terminal, rectifying a voltage caused to a secondary winding of the transformer and feeding it to a driver transistor as a collector voltage. CONSTITUTION:When pulses Vp are generated, a driver transistor 2 is forced to an on-off state, which in turn drives a transistor 1 to an on-off state. By this a voltage is caused by a loaded current to a secondary winding n2 of a transformer 8. The voltage is rectified by a full-wave rectification circuit to cause a voltage drop to both ends of a resistor 9. Because of the said voltage, an emitter to collector voltage enough to saturate the transistor 1 can be given to the driver transistor 2. Consequently, a collector to emitter voltage, when the transistor 1 is in an on-state, can be lowered to a saturable collector to emitter voltage when it is used as a single body. Therefore the collector dissipation in the transistor 1 can be minimized.

Title: Logic circuit
Inventor: FUJITA YASUHIKO
IPC: H03K19/0948
Filed: 1986-02-12
Abstract: PURPOSE:To obtain a desired current consumption by providing a constant voltage circuit sending a prescribed output with reference to a power voltage, a transistor (TR) whose gate receives an output of the circuit and whose source is connected to a power supply and a logic section using the said TR as a load so as to decrease the channel length of the TR. CONSTITUTION:The circuit comprising TRs 33-36 in the constant voltage circuit 17 constitutes a constant current circuit. Drains of the TRs 35, 36 are connected to a gate of a P-channel TR 37, the source of the TR 37 is connected to a power supply VDD, the drain is connected to the drain and gate of N- channel TR 38 and the source of the TR 38 is connected to ground. Since currents i1, i2 are always constant even when the power supply VDD is changed and the gate-source voltage of the TR 35 is always constant, the voltage at a terminal (b) viewed from the power supply VDD is constant. Since the gate- source voltage of TRs 211, 212 is constant, even when the power voltage VDD is fluctuated and increased, the current consumption is not increased.

Abstract: PURPOSE:To obtain a low power consuming piezoelectric oscillator by arranging electrodes for driving the piezoelectric oscillator flatly only on a surface engaging with a diaphragm so that the electrodes are positioned in parallel with the diaphragm and deforming the piezoelectric oscillator in two or more different oscillation modes overlapped. CONSTITUTION:Drive electrodes 7 are arranged only on one side of a piezoelectric oscillator 2. If a +V voltage is applied to a drive electrode 7-3 and other electrodes are grounded, an electric field generates in a polarized direction (thickness direction) and a vertical direction on the drive electrode 7 side of the piezoelectric oscillator 2 between drive electrodes 7-3, and 7-2 as well as drive electrodes 7-3 and 7-4. The piezoelectric oscillator 2 which becomes distorted in an arrow d15 direction deforms in a protruding form at the drive electrode 7-3 section and in a recessed from at the drive electrode 7-2 and drive electrode 7-4 sections, because the oscillator 2 is restricted on the other side by a substrate 3. If a -V voltage is applied to the drive electrode 7-3 and the -V voltage is applied to the drive electrodes 7-2, 7-4, and a drive electrode 7-10 is grounded, two different oscillation modes are overlapped to promote deformation of the piezoelectric oscillator 2.

Title: Sor generator
Inventor: MIZUSHINA TOMOYUKI
IPC: G21K1/093
Filed: 1991-02-21
Abstract: PURPOSE:To reduce an occupied space and obtain a large irradiated area by disposing deflection electromagnets upstream of an insertion light source to arbitrarily more an axis of a meandering beam inside the insertion light source. CONSTITUTION:The position and angle of a beam central orbit 2 immediately before an insertion light source 3 are arbitrarily changed according to combination of deflection electromagnets 5a, 5b. An axis of the meandering beam inside the insertion light source 3 is accordingly changed, and further, the position and direction of a radiation light source can be changed. The beam passing through the insertion light source 3 returns to the original orbit, where it is free from perturbation, owing to the combination of downstream deflection electromagnets 6a, 6b. The combination of the deflection electromagnets disposed upstream and downstream of the insertion light source 3 can produce local displacement of the beam orbit, thus eliminating an effect on other portions. Control of deflection magnetic fields of the deflection electromagnets 5a, 5b, 6a,6b and a change in time enables SOR to irradiate a large area in a short time.
