Title: Track error detecting circuit for optical disk device of sample servo system
Inventor: OZAWA YASUYUKI
IPC: G11B7/095
Filed: 1988-12-05
Abstract: PURPOSE:To minimize an influence of the damage of wobbled pits by holding the peak and sampling and holding the output of a subtracting means only at the time of discriminating the existence of a pulse from a peak detecting circuit. CONSTITUTION:When one of a pair of wobbled pits is damaged, an output (c) of a comparator 10 is obtained only for the other normal wobbled pit because one potential of a wobbled pit reproduced signal (s) is lower than a reference potential (e), and an output pulse (p) of a monostable multivibrator 13 is obtained only for the normal wobbled pit. Since only one output pulse (p) is obtained, outputs g1 and g2 of DFFs 141 and 142 do not simultaneously go to the high level, and an output g3 of a NAND gate 15 does not go to the low level. Consequently, a sampler and holder 16 does not perform the sampling and holding operation, and the track error signal sampled and held for the normal wobbled pit preceding the damaged wobbled pit is continuously taken out.

Title: Radio communication apparatus, and method for controlling gain for reception system
Inventor: MITSUME HIROYUKI
IPC: H04B7/08
Filed: 1999-10-28
Abstract: PROBLEM TO BE SOLVED: To provide a radio communication apparatus that can extend its dynamic range without causing any signal distortion. SOLUTION: A control circuit 40 detects strength of its own reception signal and transmits a control signal to a band changeover device 13 on the basis of the detection result and identification information of one of dual bands (810 MHz/885 MHz). The band changeover device 13 includes an active element and two BPFs and selects a BPF in use by selecting an ON/OFF state of the active element on the basis of the control signal. Specifically, when the signal strength is a usual level, the band changeover device 13 activates the active element to select the 1st BPF of which operating frequency is a pass band. When the signal strength is excessive, the changeover device 13 deactivates the active element to suppress a signal passing through the 1st BPF with an insertion loss thereby decreasing the reception gain.

Abstract: PURPOSE:To widen the variable range of an oscillating frequency by connecting a varactor diode in series with an inductor in addition to a capacitive component of a resonator with respect to a variable oscillator of a tuner for television reception so as to vary the inductive reactance. CONSTITUTION:The oscillating frequency depends on the parallel resonance of the capacitive circuit comprising a varacter diode 9 and capacitors 3, 4, 5, 6, 7, 11 and the inductive circuit comprising a varacter diode 8 and an inductor 10. In applying a voltage from a tuning voltage supply terminal 23 to vary the capacitance of the varacter diodes 8, 9, the capacitance of the varacter diode 9 is increased, the capacitive component of the resonance circuit is increased and the resonance frequency changes in the decreasing direction. With the capacitance of the varacter diode 8 increased, when the reactance changes from the state 25 into the state 26 in figure, the reactance of the series circuit changes from the state 27 to the state 28 and the inductance component of the series circuit is increased equivalently.

Title: Roll gap adjuster of husking separator
Inventor: HACHITSUKA KOICHI
IPC: B02B3/04
Filed: 1994-12-13
Abstract: PURPOSE: To prevent the degradation in husking ratio by judging the stabilization state of the load current sensor of a main motor and a valve opening sensor in an initial period of operation and shifting the operation to a roll gap adjusting control stroke based on the load current value reference after correction of an increase in breaker capacity when the load current value exceeds the breaker capacity. CONSTITUTION: This husking separator adjusts the roll gap of a pair of husking rolls by opening and closing the roll gap based on the load current value reference. The stabilization state of the load current sensor of the main motor and the valve opening sensor are first judged in the initial period of operation. Whether the load current value exceeds the breaker capacity or not is then judged. The roll gap adjusting control stroke based on the load current value reference of the succeeding husking rolls is started when the load current value is judged to be within the breaker capacity. The increase in the breaker capacity is so corrected that the load current value exceeds the breaker capacity but the operation can be continued for the prescribed time in case the breaker capacity is exceeded.  The roll gap adjusting control stroke based on the load current value reference is thereafter started. As a result, the extreme degradation in the husking ratio by the rapid opening adjustment of the roll gap is prevented.

Abstract: PURPOSE:To shorten time required for detecting the fault of short-circuiting one side of a TRIAC by immediately storing and holding the generation of an abnormal state without waiting over fixed time when it is judged that an electrifying waveform to a heating means is a half-wave electrifying waveform. CONSTITUTION:The second-order coil voltage of a current transformer 107 is amplified by an inverted amplifier circuit 11, and the output is integrated by an integration circuit 12. It is judged by the integrated DC voltage whether the waveform shows half-wave electrification or not. In the case of half-wave electrification, the output of a comparator 13 is made HIGH and a transistor 15 is turned ON. Therefore, a flip-flop 109 is set and a relay is cut off. In the case of full-wave electrification, the output of the comparator 13 is made LOW and the transistor 15 is turned OFF. Therefore, the flip-flop 109 is not set. Thus, when the TRIAC is set in the half-wave electrification state, this is speedily detected and after the abnormal state is stored and held, the relay can be cut off.
