Title: Stereo demodulator
Inventor: YOSHIOKA YASUHIRO
IPC: H04H40/72
Filed: 1994-08-31
Abstract: PURPOSE: To provide a stereo demodulator capable of reducing and suppressing noise on stereo demodulation signals at the time of the multi-path interference of FM reception without degrading separation. CONSTITUTION: FM demodulation signals are inputted to a sub-carrier signal generator 10 and stereo demodulation gate circuit 11. Sub-carriers are generated from pilot signals in the FM demodulation signals in the sub-carrier signal generator 10 and inputted through a pulse width conversion circuit 14 to the stereo demodulation gate circuit 11 as gate control signals. The output of the stereo demodulation gate circuit 11 is set at the separation corresponding to reception electric field intensity by separation control signals from a separation control signal generator in a separation control circuit 12, passed through a de-emphasis circuit 13 and turned to audio output (Rch and Lch).  In the pulse width conversion circuit 14, by performing setting to make the ON period of the pulses of the gate control signals shorter than an OFF period (make a duty ratio small), the stereo demodulation output appearance rate of the noise generated by multiple paths is lowered (reduced and suppressed).

Title: Check circuit for heat detector
Inventor: MORISUE KAZUNARI
IPC: G08B17/06
Filed: 1988-09-14
Abstract: PURPOSE:To highly accurately check a heat detector and, at the same time, to prevent a decline in the heat sensing characteristics of the detector by transmitting a check controlling signal and generating a detecting output by switching a heat sensing element to a dummy element for comparison. CONSTITUTION:When a no-operation check controlling signal is transmitted from a repeater 6, a signal process circuit 10 turns off analog switch elements S1 and S2 and turns on an analog switch S3 based on a discriminating result of a multiplex transmission process circuit 11 and inputs the voltage divided output between a dummy element 12b for comparison and resistance R1, namely, the voltage divided output which is not discriminated as the output indicating the start of a fire to the signal process circuit 10. If the signal process circuit 10 generates a detecting output corresponding to the start of a fire upon receiving the voltage divided output and a heat detector 2 returns detecting information corresponding to the start of the fire, the heat detector 2 is discriminated as abnormal. When the detector 2 returns the detecting information of the normal time, the detector 2 is discriminated as normal.

Patent JP-H0685248-A (JP)
Title: Horizontal insulating gate type bipolar transistor
Inventor: SUMIDA HITOSHI
IPC: H01L29/78
Filed: 1992-08-31
Abstract: PURPOSE:To prevent the occurrence of a latchup and widen the safety operating range by forming a high impurity concentration region of a first conductive type inside the extending part of a buffet region. CONSTITUTION:A high impurity concentration region of the same conductive type as a buffer region 5 instead of a collector region 6 is formed inside the buffer region 5 surrounding the end part in which the concentration of power source occurs out of a base region 2 in which an emitter region 4 is formed in the inside and a gate electrode is formed on the surface, that is, the emitter and gate region. By this, a MSFET structure is formed, and since an injection of a minority carrier does not occur in a low impurity concentration region of the structure, the concentration of the minority carrier does not occur. However, since a collector electrode is also in contact with the high impurity region, an ON current flows in the region and a current capacity is decreased. Thus, the break in a dielectric load turn-off is prevented and the safety operating range of the horizontal IGBT can be widened and simultaneously a high switching speed is attained.

Title: Varnish impregnating method for electric machine
Inventor: NISHIZAWA HIROSHI
IPC: H02K15/12
Filed: 1990-08-31
Abstract: PURPOSE:To impregnate even a narrow space with varnish effectively and to block flow out of varnish as low as posdible by covering a winding and a core with an airtight bag and impregnating the winding and the core with varnish contained in the bag while depressurizing the interior thereof. CONSTITUTION:A stator core 12 and a winding 13 are contained in an airtight bag 20 and predetermined amount of varnish is placed therein. Furthermore, a winding member 22 is fitted to the outer peripheral part of the coil end 13a. The mouth part 20a is then coupled with a pressure reducing unit which then performs evacuation and thermally sealed and finally decoupled. Since the interior of the bag is depressurized, the varnish 21 enters into narrow space such as the gap between the strands 15 or the gap between the winding 13 and a slot 12a. The stator core 12 and the winding 13 are then heated under that state thus curing the impregnated varnish. Since the varnish 21 cures while being contained in the bag 20, impregnated varnish does not flow out.

Title: Encoding/decoding circuit
Inventor: IWAMURA KEIICHI
IPC: G06F11/10
Filed: 1986-09-30
Abstract: PURPOSE:To miniaturize an apparatus by providing a decoding circuit having a means for multiplying a syndrome generated by a syndrome generating means, by a constant, and a circuit for changing its constant in case of encoding, and using multiplex a multiplying means. CONSTITUTION:At the time of executing double error correction and encoding, a syndrome generating circuit is operated by setting input data in-3-in to '0'. Therefore, a clear input of a register which has latched a receiving word J is dropped to L during in-3-in. Accordingly, when in-3=0 is being inputted, a syndrome SI=(S0, S1, S2 and S3) generated by receiving words of il-in-4 is generated. At the time of executing double error correction and encoding, when syndromes SI-SIV are drived by a syndrome generating circuit, the syndrome and a double error correction and encoding constant are multiplied in order to generate parities in-3-in. In this way, the encoding/decoding processing is allowed to flow like a pipeline, a high processing speed is maintained, and also, it is realized to make the correction capacity and the code length variable, and the circuit scale can be made small by common use of circuits and multiplexing of the circuit of the encoding/decoding circuit.
