Title: Voltage-resonance type switching power supply circuit
Inventor: YASUMURA MASAYUKI
IPC: H02M3/28
Filed: 1998-10-14
Abstract: PROBLEM TO BE SOLVED: To improve power conversion efficiency and to miniaturize and to make a circuit light in weight. SOLUTION: A secondary side DC output voltage can be obtained by a full- wave rectifying circuit (a set of [rectifying diodes D01 and D02 and a smoothing capacitor C01] and a set of [rectifying diodes D03 and D04 and a smoothing capacitor C02]), where a parallel resonance capacitor C2 is connected to increase the maximum load power at a secondary side as a voltage-resonance type switching power supply which corresponds to relatively high-load conditions exceeding 150 W in an AC input voltage AC 100 V system. A primary side is composed so that a rectification smoothing voltage at a level, corresponding to an AC input voltage level can be inputted by a normal full-wave rectifying circuit, instead of a double-voltage rectifying circuit.  Then, a boost circuit (NR, a diode DB for boosting, and a smoothing capacitor CiB), including coil winding NR to be controlled of a cross-type control transformer PRT is provided at the primary side to obtain a boost smoothing voltage. Then, by the constant voltage control operation of the cross-type control transformer PRT, control is made so that a boost smoothing voltage becomes constant, thus reducing current that flows to the coil winding NR to be controlled.

Title: Semiconductor radiation detector
Inventor: WADA MORIO
IPC: H01L31/00
Filed: 1986-12-09
Abstract: PURPOSE:To improve responsive sensitivity characteristics for a wide range of radiation by joining semiconductors with different mean atomic numbers and band gaps together. CONSTITUTION:A semiconductor 1 with narrow band gap and small atomic number and a semiconductor 2 with wide band gap and large atomic number are formed with ohmic electrodes 3 and 4, respectively, on one surface of each semiconductor and joined by heterojunction to each other at the other surface of each semiconductor. Radiation incident from the side of the semiconductor 1 is attenuated while generating hole-electron pairs. In this case, since the larger the atomic number is, the larger an absorption coefficient for radiation is, the radiation is rapidly attenuated in the semiconductor 2. Since, the larger the band gap is, the larger the generating energy of the hole-electron pairs generated with the attenuation of the radiation is, the semiconductor 1 has the larger number of the generated hole-electron pairs. Accordingly, the semiconductor 1 has larger ionization current. By thus constructing a radiation detector, the ionization current can be derived at a high efficiency for both low energy radiation and high energy radiation and responsive sensitivity characteristics are improved.

Title: Navigation device and reference station for correcting current position
Inventor: ISHIKAWA HIROKI
IPC: G08G1/0969
Filed: 1995-10-17
Abstract: PROBLEM TO BE SOLVED: To stably specify a more precise current position. SOLUTION: A portable navigation device 1 detects a current position (X, Y) by GPS satellites C and D to be received and transmits GPS information C and D to an onvehicle navigation device 2. The onboard navigation device 2 also detects a current position (Xs, Ys) from the same GPS satellites C and D. Since the position (Xs, Ys) and the position (X, Y) detected by the portable navigation device 1 are ones detected from the same GPS satellites C and D, almost similar errors occur. Accordingly, the onboard navigation device 2 calculates a difference between current positions (Xb, Yb) and (Xs, Ys) detected highly precisely by GPS satellites A to D and another sensor (α) to be received and transmits this difference as correction information to the portable navigation device 1.  In the portable navigation device 1, the current position is corrected by adding (Δx, Δy) to (X, Y).

Title: Detecting method for imbalance position of rotating body
Inventor: MUROE HIROSHI
IPC: G01M1/16
Filed: 1985-12-28
Abstract: PURPOSE:To easily detect an imbalance position of a rotating body by only a visual observation, and for instance, to perform a detection of an imbalance position of a propeller shaft of an automobile in its massproduction process, by obtaining in advance information for showing a relation of a peak of a signal obtained from a vibrometer and the imbalance position of the rotating body. CONSTITUTION:When a mark 7 for discriminating a rotational angle position is put to an optional position on the outside peripheral surface of a propeller shaft 1 and it is rotated, the propeller shaft 1 is vibrated, and by a peak of its signal, a stroboscopic tachometer 6 emits a light beam periodically, but this light emission synchronizes with a rotation of the propeller shaft 1, therefore, when the mark 7 rotated with the propeller shaft 1 is irradiated by this light emission, the mark 7 is seen so as to be still. In which position 4 of the propeller shaft 1 which is rotating the still position of this mark exists is observed. On the other hand, by clarifying a fact that the imbalance position is in a point Y of the upper part of a figure at the time point of the light emission of the stroboscopic tachometer 6, by information which has been obtained in advance, it is decided that a point A of a position which has been separated by theta deg. in the rotating direction is the imbalance position.

IPC: H04B3/46
Filed: 1996-11-06
Abstract: PROBLEM TO BE SOLVED: To specify a fault in the case that transmission sections and reception sections are connected at a ratio of 1:n (n>=2). SOLUTION: A transmission section 21 sends frame data at a specific bit location of which a specific bit pattern is inserted. Reception sections 32, 42, 52 detect the specific pattern bit from the frame data synchronously with frame signals FP2-FP4 and clock signals CLK2-CLK4 and provides an output of a detection result signal. Alarm/control multiplexer circuits 35, 45, 55 multiplex the detection result signal or the like onto alarm frame data. When the detection result signal of the reception section indicates an error entirely, a control section 61 discriminates that the transmission section 21 is faulty and the reception section is entirely normal and that only a reception section indicated to be a fault by the detection result signal is faulty and the other reception sections and the transmission section 21 are normal and produces an LED lighting signal.  LEDs 26, 36, 46 light LEDs according to the LED lighting signal.
