Title: Glass antenna system for automobile
Inventor: TAKENOBU SHOTARO
IPC: H01Q1/32
Filed: 1993-05-21
Abstract: PURPOSE:To attain excellent reception by resonating an inductance of a choke coil connected between a heater wire provided to a window glass plate and ground with a stray capacitance of the heater wire and selecting the Q to be a specific range so as to make the reception characteristic flat. CONSTITUTION:The inductance of choke coils 4a, 4b connected between a heater wire 3 provided to a window glass plate 1 and ground and a stray capacitance of the heater wire 3 are resonated. Then the Q is selected in a range of 1-8. When the Q is less than 1, the reception sensitivity around a low frequency of a desired reception frequency band is too low and when the Q is more than 8, the resonance point in the reception sensitivity gets higher by about 8dB from a flat portion and the flat sensitivity cannot be obtained. This is undesirable. When the Q is selected in a range of 1-8, the peak of the reception sensitivity is about -5 to +6dB over the flat portion and the excellent reception is attained.

Filed: 1995-06-09
Abstract: PURPOSE: To prevent abnormal growth of scale on the internal surface of a heat exchanger tube as generated after the removal of the scale on the external surface of the heat exchanger tube of a supercharger or a reheater of a boiler. CONSTITUTION: Steam oxidation scale 2 is generated on the internal surface of a heat exchanger tube 1 of a supercharger or a reheater of a boiler and atmospheric air oxidation scale 3 is generated on the external surface of the heat exchanger tube.

A part from which the atmospheric air oxidation scale 3 is removed is coated with a heat-resistant heat-insulating material 4 to repair. This enables restricting of a sharp growth of the scale on the internal surface due to a temperature rise inside the heat exchanger tube thereby maintaining the life of the heat exchanger tube at a planned value.

Filed: 1990-06-01
Abstract: PURPOSE:To eliminate the deviation of the phase of clock between a sender side MODEM and a sender side TDM (multiplexer) by resetting a data buffer when the start of an asynchronous data is detected. CONSTITUTION:An FIFO control circuit 8 sends an FIFO output clock 11 to an FIFO buffer 9 in matching with a high speed clock 6 after data of a prescribed number relating to a preceding burst number are stored in the FIFO buffer 9 so that the data in the FIFO buffer 9 are not lost from the start of transmission of a facsimile data till its end. A dummy data is sent for a while after the end of the facsimile data, but since the FIFO buffer 9 is again reset at the start of the facsimile data, the dummy data in the FIFO buffer 9 is lost. The loss of the dummy data is allowed and the synchronization is taken at the start of the succeeding facsimile data regardless of lead or lag and the phase deviation is avoided.

Abstract: PURPOSE: To improve reliability by adding the procedure of making a reception answer temporarily before the transmission and reception of data to  transmission procedures on the answerback system.  
     CONSTITUTION: If reception answer detector 13 detects a reception answer-back signal in an answer waiting mode while transmitter 1 at the center side is receiving an output command from CPU3, ST control circuit 18 sends data from transmission memory 29 via gate 26 and also sends its check code from check-code generator 21 via gate 25. As a result, its mode changes into the end waiting one of supervising the reception data of the transmitter at the terminal side. Once detector 14 detects the end code, CE control part 27 is informed of the end. When detector 13 detects the answer-back signal indicating the continuation of the operation, code generator 20 sends out the transmission request code and the mode changes into the end waiting one again.

Title: Superconductive device and production of the same
Inventor: AIHARA KATSUZOU
IPC: H01B13/00
Filed: 1977-12-02
Abstract: PURPOSE:To release the stress concentration to 3 niobium tin and control the voltage generation of superconductive wire materials at the current value below transition current by forming a superconductor compound to a nearly elliptical cross section thereby increasing the contact interface of copper-tin alloy and 3 niobium tin. CONSTITUTION:A composite superconductive wire material 1 is composed of, e.g., niobium bars 2, copper-tin alloy 3 and Nb3Ti 4. The Nb3Ti has nearly an elliptical cross section, in which the ratio a/b of the longer diameter and shorter diameter of the ellipse is within a range from 2.5 to 15. When the composite superconductive wire material is used for a coil, possible cause for its voltage generation at the current value below its transition current in the current-voltage characteristics  thereof lies in the thermal shrinkage stress at the time of low temperature owing to  the differences in thermal shrinkage rate between tin-copper alloy and niobium.  Because of this, the stress concentration to the Nb3Ti is released by employing an elliptical cross section thereby increasing the contact interface between the copper-tin alloy and the Nb3Ti.

Title: Power supply noise eliminating circuit
Inventor: TAMURA ITSURO
IPC: H02J3/01
Filed: 1990-05-31
Abstract: PURPOSE:To eliminate noise only from an AC power supply by providing a bandpass filter passing only the noise frequency components of the AC power supply, a gain or attenuation level varying means, and means for subtracting the output of the level varying means from an electric signal. CONSTITUTION:A bandpass filter 6 has a narrow bandwidth having the frequency f0 of an AC commercial power supply as a central frequency and filters only the noise frequency component of the AC power supply which is then fed on a line 7 to a rectifying circuit 8. When the noise level is high, the rectifying circuit 8 introduces a large voltage on a line 9. Consequently, an amplifying circuit 10 increases the gain or the amplification factor when no voltage is applied through the line 9. A subtractor circuit 14 suppress the high noise level in an electrical signal transmitted on the line 5 by an amount corresponding to the voltage fed through the input 16.
