Title: Controlling method for pulse-width modulation control single-phase inverter
Inventor: KONISHI YOSHIHIRO
IPC: H02M7/48
Filed: 1986-03-12
Abstract: PURPOSE:To improve the reliability of a pulse-width modulation control single- phase inverter by correcting the deviation of the frequency of the switching operations of each arm to uniformize switching losses of contacts. CONSTITUTION:A sinusoidal wave signal is output as an AC wave from a sinusoidal wave oscillator 21, and a triangular carrier signal is output in high frequency from a carrier oscillator 22. A sinusoidal wave synchronous rectangular wave oscillator 23 outputs a sinusoidal wave synchronous rectangular wave signal synchronized with a sinusoidal wave signal output from the oscillator 21 and having equal frequency. The signal from the oscillator 21 is compared by a comparator 24 with the carrier signal from the oscillator 22, and the comparator 24 outputs a pulse train signal modulated by the sinusoidal wave. The carrier rectangular wave signal of twice of the carrier signal from a carrier synchronous rectangular wave oscillator 30, a sinusoidal wave modulation pulse signal and a sinusoidal wave synchronous rectangular wave are calculated by a logic circuit, and the number of the ON/OFF operations of each arm of a single-phase inverter is uniformized by the output signal.

Title: Traveling mechanism in steel tower
Inventor: KUSHI HIROYUKI
IPC: E04G3/00
Filed: 1998-02-19
Abstract: PROBLEM TO BE SOLVED: To solve a problem of twists in a traveling rail due to unbalanced load of a self-driven work machine and, at the same time, to ease restrictions on shape design of an equipment device to be mounted thereon by obstacles around the traveling rail. SOLUTION: A steel tower stamping member 7 as a moving scaffold for a worker executing maintenance and inspection work is mounted to a steel tower (power supply steel tower). A self-driven work machine 30 executing the maintenance and inspection work on the steel tower is constituted of a traviling device 36 and a movable arm 39. The stamping member 7 is used for the traveling rail of the traveling device 36.  Since the stamping member 7 has originally high strength and sufficient torsional ridigity from the use thereof, even if torsional moment caused by partial load of the self-driven work machine acts thereon, torsional deformation is hard to occur, Since the stamping member 7 is usually attached to the outside of an arm 3 of the steel tower, obstacles to the traveling of the self-driven work machine can be reduced, and restrictions on shape desin of an equipment device to be mounted thereon can be eased.

Title: Recording retrieval device for tape recorder
Inventor: ITOU YOSHIHIRO
IPC: G11B15/02
Filed: 1981-04-10
Abstract: PURPOSE:To retrieve even a non-signal part longer than required quickly, by skipping the non-signal part through high speed retrieval again after brought to reproducing state once, when a non-signal part between recordings is detected during the high speed retrieval. CONSTITUTION:In starting high speed retrieval from a non-signal part, when a signal part is detected, reproducing state is made only for a count-up time T2 of a counter C2 and the system restores to the high speed retrieval again. In starting the high speed retrieval from the signal part, the reproducing state is made after a count-up time T1 of the counter C1 elapses, and when the next signal part is detected while the time T2, the reproduction is made for a count-up time T3. Further, when the next signal part is not detected for the time T2, the reproduction is made for the time T2, and the high speed retrieval is made until the next signal part is detected and the non-signal part is skipped. Thus, quick  retrieval can be made even for the non-signal part longer than required.

Abstract: PROBLEM TO BE SOLVED: To obtain complementary two-phase signals from a signal of a photo diode in a preamplifier circuit and to obtain a low return loss from both outputs. SOLUTION: The preamplifier circuit is provided with a FET 57 whose source electrode connects to an output terminal 205, whose gate electrode connects to a node 208 and whose drain electrode connects to a complementary output terminal 204 of a differential amplifier circuit that receives an output signal of a 1st stage inverting amplifier circuit and uses an output of an integration circuit averaging the input signal for a reference signal.

Abstract: PURPOSE:To remove the blur of the window of a reaction cell, and moreover to enable to control a chemical reaction having high selectivity by a method wherein excitation of an oscillation is performed according to infrared laser, and then molecules excited to the oscillation are excited to be dissolved according to ultraviolet laser. CONSTITUTION:SiH4 gas diluted by N2 or Ar gas is introduced in a reaction cell 31 through port openings 36, 37. Then a CO2 laser beam (infrared wavelength variable laser) 35 is introduced in parallel with the surface of an Si wafer 32. When the laser beam is formed in a sheet type using a cylindrical lens, SiH4 molecules in the neighborhood of the surface of the substrate are excited to oscillate. Then by irradiating perpendicularly by a dye laser 34 to the surface of the substrate, only excited SiH4 to the oscillation is dissolved to generate atom type Si, and an a-Si thin film is formed. Because the reaction thereof is generated only in the neighborhood of the surface of the substrate 32, the blur of a window 34 is not generated. Moreover because only the molecules selectively excited according to the oscillation level are dissolved, selectivity of the oscillation is favorable.

Title: Switching power supply device
Inventor: NAKAHIRA KOJI
IPC: H02M7/537
Filed: 1994-02-28
Abstract: PURPOSE:To improve efficiency by reducing the switching loss of a switching element at the time of small input voltage. CONSTITUTION:A capacitor C4 is charged gradually when a switching element Q1 is tuned off, and a transistor Q3 is turned on when the voltage of the capacitor C4 exceeds saturation voltage between the base and emitter of a transistor Q3. Consequently, the switching element Q1 is controlled in the direction that the off of the switching element Q1 is maintained. As a result, switching loss at the time of light load is reduced, thus improving efficiency. When load is to some extent weighted, the on period of the switching element Q1 is prolonged, a capacitor C6 is charged gradually, and a transistor Q8 is tuned on. Accordingly, the transistor Q3 is turned off, thus releasing the control action of a first control circuit 1.

Title: One-way torque limiter
Inventor: SHIBATA MAMORU
IPC: F16D45/00
Filed: 1989-03-09
Abstract: PURPOSE:To obtain a compact one-way torque limiter for stabilizing operation torque and permitting its cost to be reduced by combining a one-way sprag clutch and a slip-type torque limiter. CONSTITUTION:A sliding board 7 of a slip-type torque limiter is provided opposite to a friction board 7. This opposite face forms a slip face and slip torque is applied to it by a spring 8 variably adjusted or fixed. The slip torque has been selected so that it is larger than passing torque of a one-way clutch and smaller than its rock allowable torque. With this method, operation is possible with extremely small overrunning torque when operation is in a direction of passing, and when it is operated in a reverse direction, that is, a direction to rock, the one-way clutch is fixed and operated by the slip face of the torque limiter. Thus, specific resistance is applied to operation of the slip torque.
