Title: Fm signal demodulation circuit
Inventor: YASUI TOSHIMI
IPC: H04L27/148
Filed: 1996-01-31
Abstract: PROBLEM TO BE SOLVED: To improve the precision of demodulation by using not a sharp low pass filter for shaping the waveform of an FM signal demodulation circuit but a simple one. SOLUTION: When an FM video input signal S1 obtained by FM-modulating a carrier with a video signal is inputted to a video amplifier 1, a plus FM output signal S2 a and a minus FM output signal S22 b whose phase is deviated from the plus FM output signal S2 a by 180 degrees are outputted to differentiation circuits 2a and 2b. When pulse signals differentiated in the differentiation circuits 2a and 2b and obtained are added, a pulse output signal S3 having the frequency twice as much as the FM video input signal S1 is obtained. In the pulse output signal S3 , an apparent frequency difference between the carrier and a video signal is enlarged, and a low pass filter 3 which waveform-shapes the pulse output signal S3 can precisely demodulate the signal where the frequency difference between the carrier and the video signal is small.

Title: Electromagnetic spring
Inventor: MIHASHI CHIAKI
IPC: G01H11/02
Filed: 1980-02-14
Abstract: PURPOSE:To adapt a pendulum natural frequency governer for remote controlling by adjusting the natural frequency of a pendulum on the basis of the voltage and polarity of DC constant-current given to stiffness adjusting coils for widening the adjusting area of the governer without being influenced by mechanical restrictions. CONSTITUTION:When an electromagnetic spring is used for a vibration-detecting pendulum, a pair of stiffness adjusting coils 9a and 9b are arranged upon and under a movable coil 3. As the relative displacement X between each coil 3, 9a, or 9b and a magnetic circuit air gap 8 is changed, an electromagnetic constant G obtained by the sum total of products of a magnetic flux density B and a coil winding unit length dl is essentially unchanged in a movable coil 3, but changed in stiffness adjusting coils 9a and 9b differentially to each other. The natural frequency of the pendulum can be adjusted by changing the DC constant-current given to these coils 9a and 9b in the voltage and polarity.

Filed: 1997-01-30
Abstract: PROBLEM TO BE SOLVED: To provide a spark gap having variable length by providing electric field generating means in which insulating means is arranged to apply electrical insulation between electrical energy discharging means and the magnetic field generating means. SOLUTION: Intensity and duration of current (i) led to flow into an electrode 26 are increased for the purpose of moving an electric arc 36a up to the position of an electric arc 36c. Cylinder internal pressure is changed to a large extent between a high load condition and a low load condition. Therefore, an electric arc generated in a gap 30 is decided as the position of the electric arc 36c under the low load condition, and decided as the position of the electric arc 36a under the high load condition. An electric arc 36b shows that the position of the electric arc generated in the gap 30 can be controlled. Magnitude of current forming the electric arc 36c between electrodes 26, 28 is remarkably decreased by arranging a magnet. A divergent gap limited by the electrodes 26, 28 forms an electric arc having variable length in an ignition plug device.

Filed: 1997-01-30
Abstract: PROBLEM TO BE SOLVED: To enlarge a variable frequency range and to provide an oscillation waveform in which phase noise is less for a wide range and whose frequency stability is high by overlapping a part of the oscillation frequency variable range and synthesizing the outputs of the two systems of a PLL circuit. SOLUTION: The two systems 10 and 11 of the PLL(phase locked loop) circuit 2 constituted of VCXO(voltage controlled crystal oscillation) 1 and 2 which are adjacent and whose partial parts are overlapped are prepared. A low pass filter 3 where attenuation quantity increases near the upper limit of the oscillation frequency variable range of the PLL circuit 10 and a high pass filter 4 where attenuation quantity reduces near the lower limit of the oscillation frequency variable range of the PLL circuit 11 are connected to the outputs of the circuits 10 and 11. An adder 5 is connected to the outputs of the filters 3 and 4. Since the deviation of the lock phases of the PLL circuits 10 and 11 in the two systems is fine, the output of the adder 5 is considered to be equal to the sum of the absolute value of the outputs of the filters 3 and 4, and it becomes constant.  When the phase comparison frequency of the phase of the output waveform from the adder 5 is raised, specific gravity which the output of the PLL circuit 11 occupies increased from '0' and the ratio which the output of the PLL circuit 10 occupies reduces from 100% to '0' and the interruption point of the phase does not exist.
