Title: Offset four-phase phase demodulator for modulation signal
Inventor: YAMAUCHI EIJI
IPC: H04L27/22
Filed: 1986-10-22
Abstract: PURPOSE:Not to cause a step out in a PLL circuit even if the lock phase position of a reproduced carrier signal is transited by generating the inverted edge pulse of two different demodulation axis signals, ORing in an OR circuit and inputting the output in the PLL circuit for data reproducing clock. CONSTITUTION:The inverted edge pulses of two different demodulation axis signal outputted from synchronous detectors 1a and 1b are respectively generated in data edge detectors 7a and 7b and the OR is obtained in the OR circuit 9 so as to be inputted in a phase comparator 11 in the PLL circuit for data reproducing clock. AND between the output from one edge detector 7a and the one from the PLL circuit is obtained in an AND circuit 8 and its output is supplied to the clear terminal of a divider which divides the output from the PLL circuit into half. Thus, if the lock phase position of the reproduced carrier signal is transited and the converting point of two demodulation axis signals jumps by a half symbol, the PLL circuit does not cause the step out and the demodulation axis signal can be identified in terms if code with enough wind margin.

Title: Drum type washer
Inventor: HOSONO TOSHIAKI
IPC: D06F21/04
Filed: 1989-09-26
Abstract: PURPOSE:To suppress oscillation when the washer is operated and to automatically manage cleaning, dehydration, and drying cycles by detecting the oscillation and the change of weight with a distortion sensor. CONSTITUTION:The distortion sensor 6 mounted at a horizontal supporting plate 4 detects the weight of wash and water, etc., in the inside of a rotary drum 3, and detects the oscillation when the rotary drum 3 is rotated. When the wash 10 is thrown in the rotary drum 3 and the water 11 is supplied, the horizontal supporting plate 4 is deformed with the weight Z of the wash 10 and the weight Y of the water 11, and the output of the distortion sensor 6 is varied, and detection weight is detected as (Z+Y). When a rinsing operation is completed, the water is drained from a water tank 2, and assuming the weight of the wash 10 containing the water as X, gross weight goes to X. The output signal of the distortion sensor 6 is decreased, and is kept almost constant, therefore, a microcomputer assumes it as the completion of drainage, then, a mode is migrated to a dehydration operating mode. The rotary drum 3 is operated starting from low speed, and when remarkable oscillation occurs and the output of the distortion sensor 6 arrives at a specification value, the forward and backward rotary driving of the rotary drum 3 are performed, which unravels the wash 10. When the output of the distortion sensor goes less than the specified value, the rotary drum 3 is operated at a high speed.

There is no possibility that the internal pressure of the remote control case 1 exceeds the pressure under which a push switch S operates in the normal application eliminating malfunctioning of the push switch S. A moistureproof member 3 allowing air to pass but none of water is spread on the vent hole 2 to close it and cuts the water drops to be kept from entering the remote control case 1 from the vent hole 2.

Title: Modulation system
Inventor: MURAKAMI YUTAKA
IPC: H04L27/34
Filed: 1998-09-04
Abstract: PROBLEM TO BE SOLVED: To make signal point amplitude of a binary phase modulation system larger than maximum signal point amplitude of a multivalued modulation system without affecting a peak power to mean transmission power ratio by regularly inserting the binary phase modulation system instead of a pilot symbol and arranging signal point positions of the binary phase modulation system at the positions that are different from signal points taking maximum amplitude of the multivalued modulation system. SOLUTION: The maximum signal point amplitude of a signal point of a hexadecimal amplitude phase (16APSK) modulation system in an in-phase I- orthogonal plane is defined as (r) 16APSK. In such a case, when signal point amplitude of a binary phase (BPSK) modulation system is defined as (r) BPSK, signal points of the BPSK modulation system are arranged so as to be (r) BPSK>(r) 16APSK. Thus, frequency offset between a transmitter and receiver and the estimated accuracy of amplitude distortion quantity are improved when a modulating side performs semi-synchronous detection, bit error rate characteristics in a carrier power to noise power ratio are improved and high sensitive reception can be performed.

IPC: G11B11/10
Filed: 1991-09-30
Abstract: PURPOSE:To execute highly reliable information reproduction by controlling favorably a threshold at the time of shaping the waveform of a magneto-optical disk reproduced signal even in the case that the amplitude of the reproduced signal varies and in the case that there is a defect on a recording medium. CONSTITUTION:The positive and negative direction peak values of the reproduced signal of specified data recorded before a data area are made initial values, and the maximum value and the minimum value of the amplitude of the reproduced signal are held by a peak detection circuit 4. A threshold to be the center of the amplitude of the reproduced signal is generated by a threshold generation circuit 5, and the waveform is shaped by a waveform shaper 6. Besides, since a defect detection circuit 1 observes a pit signal, and in the case that there is the defect in the recording medium, it outputs a control signal to cut out the input of the peak detection circuit 4 to a switch 3, the peak detection circuit 4 never holds erroneous peak value due to the defect of the recording medium, and the threshold generation circuit 5 does not receive the influence of the defect of the recording medium.
