Title: Driving circuit of brushless motor
Inventor: YAMAUCHI MASAYA
IPC: H02K29/00
Filed: 1990-06-05
Abstract: PURPOSE:To perform smooth rotation control with quick response like a brush motor by providing a means, which switches the application voltage according to rotation control by pulse control and smoothes it, at the previous stage of a driver stage, which controls the current application of a stator coil. CONSTITUTION:A linear acceleration circuit 3 is provided at the previous stage 2 of a driver, which controls the timing of current application. When a transistor Q3 is turned on or turned off by a PWM control signal (to be exact, an inversion signal), driving power voltage +Vcc is switched with the pulse width of the PWM control signal. This switching waveform is smoothed with a capacitor C1 and becomes a smoothly changed waveform, and the excitation of the coil also is performed with smooth change. Accordingly, the same control as changing the supply voltage to a conventional brush motor by drop control control method is performed.

Title: Ultrasonic combusting apparatus
Inventor: TAKEMOTO MITSUTAKA
IPC: F23D11/34
Filed: 1979-11-12
Abstract: PURPOSE: To ignite fuel in reliable manner without preheating the fuel by an electric heating means in the combusting apparatus of the type in which liquid fuel such as kerosine oil is combusted after it is atomized by use of ultrasonic vibration, by lowering the output for driving a combusting-air feeding fan at the intial stage of operation and thereby restricting the amount of primary air to be supplied for combustion of fuel.  
     CONSTITUTION: When operation switches 21, 21' are closed for starting operation of the combusting apparatus, a relay switch 23 is closed by a relay coil 28 with an extinction switch 22 and a liquid-level detecting switch 27 being kept closed, so that a self-holding circuit is formed. Therfore, the fuel in a fuel vaporizing chamber is atomized by an ultrasonic vibrator 4 which is driven by an electronic circuit 29 and carried via a vaporizing chamber to a plate formed with flame holes after it is mixed with combusting air supplied from a combusting-air feeding fan 25. Then, the air-fuel mixture is ignited by discharging electrodes which are connected to an igniting transformer 17. Here, since a thermostat 11 is opened at the initial stage of operation when the temperature in the vaporizing chamber is low and resistances 32, 34 connected in series in a resistor A are applied to fan 25, air supply rate is kept low and therefore the fuel can be ignited without fail.

Filed: 1989-06-09
Abstract: PURPOSE:Not to allow a bird to be balanced by setting an adjacent interval of a plurality of bars to a width in which birds cannot grasp by crossing over it with leg fingers. CONSTITUTION:Supports 1, 1' are formed planely in a hexagonal shape, bars 2, 2,... are anchored at the corners, and totally six bars 2 are held at an equal interval from each other. The size of each side of the hexagonal shape is so set to a value in which birds cannot simultaneously grasp by crossing over the interval of the adjacent bars 2, 2,... with leg fingers. The leg fingers of the bird to be of a reference are designated to be largest of birds to be removed at a place using a bird damage preventive tool. Accordingly, the interval is determined according to the type of the birds grouped at the place to be used. Thus, the bird cannot simultaneously grasp the two bars and cannot be balanced on the tool.

IPC: C23C14/56
Filed: 1995-06-14
Abstract: PURPOSE: To form a uniform film on full surface of a substrate in a state of eliminating the warpage of the substrate even when the substrate is large sized at the time of forming a thin film on the substrate by vapor deposition. CONSTITUTION: The film is formed by horizontally setting a wire-like vaporization source 4 and while moving the substrate 2 placed parallel to the vaporization source 4 with a prescribed interval in the vertical direction at a fixed rate. The warpage is not generated even when using the large sized substrate since the substrate 2 moves in the vertical direction. Being horizontally set, the vaporization source 4 is free from dropping or falling down.

Filed: 1985-07-03
Abstract: PURPOSE:To enable a range measurement removing the effect of an interference by using an active system at a different frequency with a passive system even when the passive system is used. CONSTITUTION:A first transmitter-receiver 1 repeats a transmission and a reception by an active system at a first frequency under the control of a controller 4. The output signal of the transmitter-receiver 1 is converted to a transmitting sound wave 51 with the first frequency by a transmitter-receiver 3, reflected by a target 50 to be a receiving sound wave 52, reaches the transmitter-receiver 3 and led to the transmitter-receiver 1. The range to and the azimuth of the target 50 are detected to form a target signal 103. At his time, a radiation noise 53 from the target 50 is received through the transmitter-receiver 3 and, when the noise 53 becomes equal to or larger than a value determined in advance, the transmitter-receiver 1 is changed over to a passive system by a system changeover signal 102 from the controller 4 and detects the azimuth of the noise 53, producing an output as a part of the signal 103. At the same time when the transmitter-receiver 1 is changed over to the passive system, a second transmitter-receiver 2 of the active system is operated at a second frequency and the use of both the systems enables a range measurement removing the effect of an interference.

Title: Protective circuit for high voltage transformer
Inventor: IKEUCHI HIROSHI
IPC: H04N3/20
Filed: 1989-06-09
Abstract: PURPOSE:To protect a high voltage transformer by conducting a semi-conductor switching element upon increase of primary current and blowing a fuse off thereby stopping current supply to a high voltage coil. CONSTITUTION:Upon increase of primary current IB, voltage drop across a current detection resistor R1 increases. When the voltage drop exceeds over a predetermined level, a semi-conductor switching element SCR is conducted. The semi-conductor element SCR is connected between the neutral point of the primary coil N1 and the source side EB of the fuse F1, and forming a closed circuit. Upon conduction of the semi-conductor switch SCR, pulses occurring at the neutral point of the primary coil N1 are shortcircuited to cause a large current. The fuse F1 is blown off by the large current and current supply to a high voltage transformer 10 is interrupted. By such arrangement, heating or firing of the high voltage transformer 10 can be prevented reliably.
