Title: Abnormality detecting circuit of power converter
Inventor: IKEDA KATSUMI
IPC: H02M7/48
Filed: 1995-12-21
Abstract: PROBLEM TO BE SOLVED: To control an inverter only by one voltage detector by specifying the abnormal state of a voltage detector when the output of an adder exceeds a specified value, and performing the protecting action for a power converter by a fault processing circuit. SOLUTION: Since the algebraic sum of respective line voltages VUS, VVW and VWU is O in principle, the output of an adder 1 is 0 when a voltage detector 14 is normal. When abnormality is caused at a part of the voltage detector 14, however, the output of a certain magnitude is generated in the adder 1. The output is detected by a comparator 2, the abnormal signal of the voltage detector 14 is outputted and an inverter 10 is stopped. Since there is the detection error in the voltage detector 14, it is necessary to provide the adequate detecting width so that the comparator 2 does not judge the detection error as the abnormality. In this way, the control of the inverter and the protection of a load can be performed without using independent voltage detectors for the control and the protection, respectively.

Title: Prevention of falling stone, prevention guard fence for snowslide, and pocket type prevention net of falling stone
Inventor: KUBOTA TOSHIO
IPC: E01F7/04
Filed: 1997-11-17
Abstract: PROBLEM TO BE SOLVED: To secure a shock-resistant property by spreading a protection net between posts of a fence body erected on a slope face and laterally stretching ropes to extend the lateral ropes when a specified tension acts between the posts and spreading wire netting on the lateral ropes. SOLUTION: A support rope 61 connected to a shuffle body 54 of a post 5 is fitted to a metal tool 62 of a buffering part and the hook of the metal tool 62 is fixed to the base 63 in an erection part of a fence body. And the fence body is erected on a slope face A. Even when fallen snow slides, it is received by the fence body to prevent a large snowslide. In this time, when a tensile force larger than a specified value acts on lateral ropes 31 of a protection net, the ropes are elongated against the holding force of the metal tool 1 at the buffering part. And when a shock larger than the holding force of the connection metal tool 2 at the crossing part acts on the connection part of the crossing part of the vertical and lateral ropes 31, 32, the crossing connection position is shifted.  And further, when an impulse acts on the whole body of the protection net, a support rope 61 is elongated against the holding force of the buffering metal tool 62. In this way, the shock-resistant capacity of the whole body of the snowslide prevension fence is increased and the usability can be increased.

Title: Resonance frequency adjustment method for microstrip antenna
Inventor: YABE TAKAKIYO
IPC: H01Q13/08
Filed: 1991-11-22
Abstract: PURPOSE:To adjust the resonance frequency without remodeling the electrode. CONSTITUTION:A hole 15 is formed to a side face of a dielectric board 10 between a radiation electrode 11 and a ground electrode 12 to decrease the effective dielectric constant of the dielectric board 10 or a dielectric substance is packed to the hole 15 to increase the effective dielectric constant thereby increasing/decreasing the resonance frequency for the adjustment. When the effective dielectric constant is increased, the resonance frequency is decreased and when the effective dielectric constant is decreased conversely, the resonance frequency is increased. Thus, the resonance frequency is adjusted in both the increasing and decreasing directions.

IPC: A61F13/53
Filed: 1997-12-04
Abstract: PROBLEM TO BE SOLVED: To obtain a water and solvent-absorbable fiber structure having the same fiber strength even in a water or solvent-absorbed state as that in a dry state by forming a layer of the crosslinked product of a (co)polymer of an N-vinylcarboxylic acid amide monomer or the monomer and an acrylic acid monomer on the surface of a water-nonswellable fiber.

Title: Filament preheating circuit
Inventor: KATO HIROJI
IPC: H05B41/04
Filed: 1988-12-28
Abstract: PURPOSE:To ensure highly reliable preheating operation by preheating a filament with constant current and comparing voltage applied to the filament with the predetermined voltage for turning on and off a preheating circuit. CONSTITUTION:Current determined with a constant current supply 15 is made IR and when this current IR flows to a filament 11, this filament 11 is heated and the temperature thereof rises. With an increase in the temperature of the filament 11, the resistance thereof changes from (r) to (r2) via (r1). In addition, voltage applied to the filament 11 changes from r0XIR to r2XIR via r1XIR, with the lapse of preheating time. As a result, when the voltage applied to the filament 11 exceeds a reference power supply 12, a comparator 13 operates, thereby actuating a thyristor 14. This thyristor 14 after operation causes the short circuit of Zener diode 8 and interrupts the current from the constant current supply 15, thereby terminating preheating operation.

Title: Power conversion apparatus
Inventor: SATO SHINJI
IPC: H02M7/537
Filed: 1998-11-25
Abstract: PROBLEM TO BE SOLVED: To provide a power conversion apparatus in which a noise is small, in which the electric stress of a switching element is small and whose conversion efficiency is good. SOLUTION: In this power conversion apparatus, when a transistor 3 is turned off, surplus electric power from a primary winding 2A and a primary winding 2B is charged in a capacitor 4A and a capacitor 4C. On the other hand, when the transistor 3 is turned on, the charged electric power is commutated by a closed circuit which is composed of the transistor 3, the primary winding 2B, a reflux diode 5B and a reactor 5D while a current peak is being suppressed by the reactor 5D, and electric power is transmitted to a secondary circuit 6. Accordingly, the surplus electric poweris not wasted, and the capacitors 4A, 4C are discharged completely until the transistor 3 is turned off again. As a result, even when the surplus electric power is generated again, the voltage rise rate of the collector-to-emitter voltage of the transistor is suppressed, and also a noise can be removed.
