Title: Brushless exciter for synchronous generator
Inventor: OKAZAKI TOSHIO
IPC: H02P9/30
Filed: 1985-07-15
Abstract: PURPOSE:To inhibit the sudden rise of output voltage from a brushless exciter on the fixing of voltage by bringing an input to a gate pulse generator to predetermined voltage on the fixing of voltage. CONSTITUTION:Field currents (IFEX) are adjusted by controlling a thyristor rectifier 7 at phase determined by a deviation between an output from a voltage setter 10 and real voltage on normal operation. On the other hand, IFEX are fed through an initial exciting circuit 6 from a battery 5 in a station on the fixing of voltage. The phase of gate pulses is brought to a fixed value simultaneously by a voltage setter 14 for fixing voltage. When voltage rises and reaches 70%-80% of rated voltage, a voltage detecting relay 13 is operated and the same control as normal operation is conducted.

Title: Brushless motor drive circuit and brushless motor
Inventor: TAKAHASHI HISASHI
IPC: H02P6/08
Filed: 1999-06-01
Abstract: PROBLEM TO BE SOLVED: To obtain a brushless motor which is operable over a wide rotational region, while decreasing the number of signal lines by driving the brushless motor in sine wave PWM system at a low speed and driving it in square wave PWM system at high speed. SOLUTION: A drive circuit 10 comprises a speed control circuit 20, performing current control at low speed using the signal from a Hall sensor 70 and performing speed control at a high speed. When the reverse voltage level of a coil increases due to high speed rotation, a brushless motor is driven in square-wave PWM system by detecting the timing of three-phase 120 deg. conduction from the correlation voltage of counter-electromotive force in coils of phase U, phase V and phase W. During low-speed rotation, where the level of counter-electromotive force is low, the coils of the phase U, phase V and phase W are driven in sine wave PWM system respectively different in phase by 120 deg., based on the detection signal of phase U of one Hall sensor 70.  According to the arrangement, the brushless motor can be controlled correctly from a high speed to a low speed, using a single Hall sensor and can be driven smoothly over the entire rotational region, while suppressing pulsation.

Title: Production of faulty dictionary
Inventor: NISHIDA TAKAO
IPC: G06F17/50
Filed: 1986-07-02
Abstract: PURPOSE:To improve the decomposition factor with production of a trouble dictionary by calculating the trouble transmission sensitivity of the input pin of each element in a computer circuit and discontinuing the backward tracing to the signal line having its trouble transmission sensitivity set at 0. CONSTITUTION:The signal name with which the value of a signal line is fixed at 0 or 1 in a normal working mode of a device and the logical value of said signal name are given as the fixed value signal information 10. A logical simulation part 100 sets a fixed value signal line at the designated logical value with other signal lines set at unfixed values respectively for execution of simulation. A trouble transmission sensitivity calculation part 200 calculates the trouble transmission sensitivity of the input pin of each element. A cover area extraction processing part 300 starts the backward tracing through a trouble detecting circuit and extracts the noticed source element. This tracing is discontinued if the trouble transmission sensitivity is equal to 0. When all tracing actions are through, the exchange units extracted in the tracing mode are registered to a faulty dictionary 30.

Title: Serial signal separation circuit
Inventor: KOZUKA NAOKI
IPC: H04J3/04
Filed: 1989-06-16
Abstract: PURPOSE:To miniaturize a circuit and to economize the circuit by integrating a synchronization detection circuit and a separation control circuit as a synchronization control circuit, allowing the synchronization control circuit to generate a separation selection signal from a serial signal and outputting the serial signal after separation with the separation circuit. CONSTITUTION:A synchronization detection circuit 8 and a separation control circuit 9 used in a conventional circuit are integrated as a synchronization control circuit 5, separation selection signal 4 is generated from a serial signal 1, separated by a separation circuit 6 to generate a serial signal 3. When no synchronization is detected, the synchronization control circuit 5 detects a synchronous signal with an output from a frame memory. When the synchronization is detected, the detection of synchronization is confirmed again even after one multi-frame and the separation selection signal 4 is generated by the control counter. The operation is repeated at the position of the synchronous signal till a signal other than the synchronous signal is detected. Thus, the output of the serial signal 3 after the separation is prevented after the separation of synchronization undetection and the circuit is simplified.

Title: Catalyst for cleaning nox-containing exhaust gas and cleaning method
Inventor: SATOKAWA SHIGEO
IPC: B01D53/94
Filed: 1996-05-27
Abstract: PROBLEM TO BE SOLVED: To obtain a catalyst having catalytic activity equal to or more than a catalyst obtained by supporting iron on mordenite by ion exchange with respect to an exhaust gas cleaning catalyst containing NOx composed of iron- containing mordenite or adding iron into the structure of mordenite. SOLUTION: A catalyst for cleaning NOx-containing exhaust gas is obtained by supporting iron on mordenite by infiltrating iron into mordenite. The NOx- containing gas is purified by bringing the NOx-containing exhaust gas into contact with the catalyst wherein iron is infiltrated into mordenite to be supported on mordenite in the presence of a reducing agent. The NOx-containing exhaust gas is cleaned by bringing combustion exhaust gas generated by the combustion of a dilute combustion system into contact with the catalyst wherein iron is infiltrated into mordenite to be supported on mordenite. More good effect is obtained if mordenite low in an SiO2 /A2 O3 ratio and good in crystallinity and mordenite having a large number of high acidity points are used.

Title: Superconductive magnet
Inventor: HATTA SHINICHIRO
IPC: H01B12/06
Filed: 1989-06-16
Abstract: PURPOSE:To obtain high superconductive current in a highly impressed magnetic field by disposing a magnetic field generated by a magnet in parallel to the film face of a superconductor thin film coil. CONSTITUTION:In a superconductive magnet using a thin film coil, each fluxoid quantum 1 is trapped by a superconductive thin film where the film face of a thin film is disposed in parallel to a generated magnetic field. Then, the film face is set to a position from which each fluxoid quantum does not move easily even though its quantum receives a driving force by a reciprocal action with superconductive current. If the fluxoid quantum 1 does not move easily, resultant macro critical current density is obtained in a high magnetic field. In this way, even though its magnet is used at a temperature that is higher than 77K, its application makes sufficient high electric current flow under stable conditions.
