Title: Receiver
Inventor: IWAHASHI KOUJI
IPC: H03H19/00
Filed: 1982-03-05
Abstract: PURPOSE:To eliminate a clock generator, a squelch wave detector, etc. for a receiver containing a switched capacitor filter included in an audio frequency amplifier, by producing the waveform of an intermediate frequency signal and then using it as a clock signal. CONSTITUTION:The intermediate frequency signal applied to an input terminal 1 is amplified by an intermediate frequency amplifier 2 and coverted into an audio frequency signal after undergoing a phase wave detection of a frequency discriminator 3. The audio signal is selected and amplified by an audio frequency amplifier 4 including a switched capacitor filter. In this case, the clock of the switched capacitor filter is produced by extracting an intermediate frequency signal out of a proper interstage output point of the amplifier 2 and then giving waveform shaping to the extracted frequency signal. Furthermore the operation of a waveform shaping device 9 is discontinued if the amplitude of the intermediate frequency signal applied to the terminal 1 is smaller than the threshold value. As a result, a squelch function is also realized.

Inventor: HATTORI MASAYUKI
IPC: H03M13/00
Filed: 1999-02-12
Abstract: PROBLEM TO BE SOLVED: To improve error-correcting capability as to pseudo-product codes by performing an error correction code repetitive decoding process for an error- correcting process by performing a decoding process repeatedly more than once as to a symbol sequence forming a converted product code code word. SOLUTION: Through a converting process, pseudo-product code codes word are converted into product code code words, by subtracting a subtraction code generated by a subtraction code generating process from a symbol sequence of pseudo-product code code words. Then an error correction code repetitive decoding process which performs error-correcting process by decoding the symbol sequence forming the converted product code code words repeatedly more than once is performed. For example, an error correction code decoding part 5, that a recording and reproducing device is equipped with, inputs a pseudo- product code from an input terminal 30, corrects an error of information symbols of a 1st series, and outputs the result from an output terminal 38.  Furthermore, information symbols of a 2nd series are outputted from an output terminal 40 from a 2nd series information symbol extracting part 39.

Title: Demodulator for multi-value quadrature amplitude modulation system
Inventor: SATO KAZUMASA
IPC: H04L27/22
Filed: 1997-02-19
Abstract: PROBLEM TO BE SOLVED: To increase a rising speed of the demodulation when a reception signal is restored by detecting interruption of the reception signal so as to reset a control voltage that compensates a DC offset of a demodulation signal. SOLUTION: Error signals 103a, 103b outputted from A/D converters 4a, 4b are given to control voltage generators 6a, 6b, where the signals 103a, 103b are converted into analog control voltages 10a, 10b and they are fed to subtractors 3a, 3b. A demodulation signal and the control voltages 10a, 10b are subject to subtraction processing and a deviation of a DC offset in the demodulation signal is compensated. In the control state, when the reception signal is lost, an input interruption detection circuit 7 outputs an input interruption detection signal 111. The input interruption detection signal 111 is given to control voltage generators 6a, 6b, built-in switches are operated and a control voltage is reset to an initial value. In the case that the input signal is recovered in this state, since the control is started while the control voltage is reset, locking is conducted quickly.

Title: Sealed alkaline cell
Inventor: YANAGIHARA NOBUYUKI
IPC: H01M10/52
Filed: 1981-03-10
Abstract: PURPOSE:To prevent the elevation of the internal pressure of a cell by occluding hydrogen gas produced in the cell and to improve the reliability of the cell by a construction wherein a hydrogen-occluding material made of alloy is mounted on a portion in the gaseous phase in the cell. CONSTITUTION:There are shown a cell case 1, an insulating plate 2, a lead wire 11 of an anode, a lead wire 12 of a cathode, and a hydrogen-occluding material 13 installed on the upper insulating plate. When a sealed alkaline cell is charged with power rapidly, the cell occludes low pressure hydrogen gas generated at the time of overdischarging, giving effect to the reduction of pressure in the cell, and will never increase the internal pressure again because it will not discharge the hydrogen it has occluded once at the normal temperature. Accordingly, when the cell is incorporated into portable equipment, it is unnecessary to worry about abnormal pressure, gas leakage and the like, while the reliability of the cell is improved.

Abstract: PURPOSE:To perform the adjustment of a pedestal level in an extremely short time when a video signal is inputted again by controlling a switching part when the input of the video signal is cut off, and fixing the pedestal level in a device at a fixed value. CONSTITUTION:When the input of the video signal (a) is cut off, an input cut-off signal (f) sent from an input cut-off detecting part 4 shows the absence of input.

The reference signal (e) is provided with a fixed value, and is set, for example, at a voltage of 1/2 the maximum offset voltage. The offset adjusting part 1 to which the reference signal (e) is inputted outputs a normal signal of pedestal level inputted from the fixed level generating part 6 in a state where the input is cut off. When the video signal (a) is set at an input state again, the input cut-off detecting part 4 controls the switching part 5 by the input cut-off signal (f), and inputs a decision signal (d) to the offset adjusting part 1, which makes it return to an ordinary operation.

Abstract: PURPOSE:To prevent data loss due to the decrease in a battery by detecting the battery voltage drop with a voltage detection circuit and inverting all read signals with write of signal through inversion. CONSTITUTION:When a write signal is outputted from a shift register 5, a signal changeover means 9 switches an input of the shift register 5 to inhibit a succeeding signal write and a data is circulated in the shift register 5. At readout, a signal read from the shift register 5 is given to a resonance circuit 1 to absorb the resonance and the data is sent externally. Then a battery voltage is detected by a voltage detection circuit 17 and when the voltage level is lowered, a data read from the shift register 5 is inverted and sent externally. Thus, the voltage drop of the power supply is detected and data loss due to battery drop is prevented.
