Inventor: CHIN ERU CHIYAN
IPC: G01C19/72
Filed: 1994-07-20
Abstract: PURPOSE: To enhance the performance of an optical fiber gyro by making an optical wave guide or a phase modulator contain lithium ions which are sufficient to substantially instantaneously change the phase of an optical signal, which passes the waveguide or the phase modulator when an electric signal is given, into a value as desired, thereby eliminating a phase relaxation substantially. CONSTITUTION: The optical waveguide or the phase modulator contains a lithium ion which is sufficient to substantially instantaneously (within a time not exceeding about one micro-second) change the phase of an optical signal passing the waveguide or modulator, when a prescribed electric signal is given to the waveguide or modulator, into a value as desired. In addition, the waveguide or the phase modulator may contain a titanium ion. In manufacturing the waveguide and the phase modulator, the lithium niobate-contained waveguide is heat-treated at about 1000 deg.C, prior to a proton exchange and annealing.  In the heat treatment. a sufficient quantity of lithium ions are difused within the waveguide or the phase modulator, under the atmospheric pressure and under the presence of a sufficient quantity of oxygen and a sufficient quantity of lithium niobate powder or other lithium ion supply source.

Title: Speed modulation circuit
Inventor: TOYOSHIMA SATOSHI
IPC: H04N5/208
Filed: 1999-06-15
Abstract: PROBLEM TO BE SOLVED: To provide a speed modulation circuit which can perform proper speed modulation only when thickening of a beam actually occurs regardless of the setting of a contrast and the amplitude of an input signal, and accordingly can prevent deterioration of picture quality that is caused by the thickening of the beam or the excessive speed modulation. SOLUTION: A level detection circuit 11 of this speed modulation circuit detects a part having a level higher than a prescribed DC level of the output of a contrast amplifier 4 and acquires a level detection signal. An area pulse generation circuit 12 adds the prescribed pulse width β to the level detection signal in response to a filter setting signal to generate an area pulse. A primary differentiation circuit 3 applies the primary differentiation to an input video signal to acquire a speed modulation signal. The amplifier 4 amplifies the speed modulation signal. A gate circuit 13 gates the output signals of an amplifier 8 only for a period of the area pulse and acquires a speed modulation output signal.

IPC: G10H1/00
Filed: 1992-06-04
Abstract: PURPOSE:To improve a musical performance effect by varying a tone color of a keyboard in which a smaller key number is detected, among two arbitrary keyboards in accordance with its parameter, in the case the obtained parameter is positive. CONSTITUTION:Key numbers of depressed keys of both the upper and the lower keyboards are compared, and in the case the key number of the lower keyboard 13 is larger than that of the upper keyboard, exceeding a reference value, a tone color of the upper keyboard 12 is controlled by a voltage control filter VCF circuit 15. In this case, when the keys of the upper keyboard 12 and the lower keyboard 13 are depressed, a key position detecting circuit 14 detects the key number of its key, and supplies its data to a control circuit 10. In this case, in the case a parameter (P) supplied from the control circuit 10 is negative or '0', control of the tone color is not executed and the tone color is not varied. In the case the parameter (P) is positive, the tone color allocated to the upper keyboard 12 is varied by controlling the sound volume and the harmonic constitution. In accordance with a P value, how to vary the tone color is different, and the larger the P value is, the larger the tone color is varied.

Title: Monitor device for pulse signal
Inventor: MINAMI HIDEAKI
IPC: H03K5/19
Filed: 1980-11-29
Abstract: PURPOSE:To monitor a pulse signal easily, by generaging a timing signal from the pulse signal itself and detecting the normality or abnormality of pulses by both signals. CONSTITUTION:An integral network 41 integrates the output voltage of a D/A converting circuit 3 and is reset by an input pulse A. An output B of the circuit 41 just before reset is stored in an analogue memory 6. If the pulse period becomes short, an output C of a comparator 10 is in the H level because an output F of a subtracting circuit 8 which outputs the output B as it is does not reach a set level; and when the pulse A is applied to a set terminal S of a reset preference FF12, the FF12 is not set, and a detection output Z is generated. If the pulse A is dropped out, the output B exceeds the output of the memory 6 to start the operation of an integral network 12, and the output F of the subtracting circuit 8 becomes lower than the set level, and therefore, the detection output Z is generated similarly.

Title: Headrest driving control apparatus
Inventor: IMAIZUMI TOMOAKI
IPC: B60N2/90
Filed: 1987-07-06
Abstract: PURPOSE: To automatically set a headrest to an optimum position by providing a head detecting means by which whether or not the head part of an occupant sitting on a seat is detected in correspondence to the headrest, by driving the headrest while monitoring the detecting information of the head detecting means, and by positioning the headrest making a reference of the position where the detecting information is changed. CONSTITUTION: The threshold value is a set value actually measured of the oscillating frequency of an OSC when an occupant sits down on a seat and the headrest is elevatedly driven, and the flag is set as the head top has been detected, when the value of a resistor RC or the increment of frequency data for 0.1 second exceeds this threshold value. When the flag is set by detecting the head top part while elevatedly driving the headrest for monitoring the flag, a timer is cleared and started for directing the de-enerizing of a relay RL1 and the energizing of a relay RL2 to a relay driver 2, so that the motor is reversely energized. Thus, the headrest is lowered as much as a prescribed value from the position for detecting the head top part, and is finely adjusted to an optimum position.

Abstract: PURPOSE:To reproduce a picture having an excellent picture quality by providing a circuit having a low output impedance regardless of 8 signal amplitude, a polarity, and an output current direction for the output of a circuit to impress a video signal on a horizontal scanning driver. CONSTITUTION:The bases of a transistor(TR) 15 are connected to the anode of a diode 9 and the cathodes of diodes 8 and 12, the bases of TR 16 are connected to the cathode of a diode 10 and the anodes of diodes 13 and 11, and the TRs 15 and 16 constitute a push/pull circuit.

Even when input floating capacity exists at a horizontal scanning driver 26, the output waveform is hardly distorted. For this reason even when the input floating capacity of the horizontal scanning driver 26 is large, since the video signal is hardly distorted, excellent picture can be reproduced.

Abstract: PURPOSE:To control the modulation sensitivity to be constant at all times over a wide carrier frequency range by utilizing a signal of a constant level in a modulation input signal or applying a modulation sensitivity correction signal of a constant level so as to detect the modulation sensitivity of a voltage controlled oscillator at all times thereby controlling a variable gain amplifier. CONSTITUTION:A modulation sensitivity detector 8 demodulates an oscillation signal output of a voltage controlled oscillator 4 at a frequency modulation signal demodulator 12 and recovers a signal similar to a modulation input signal. Then only the signal component of the prescribed amplitude is extracted among the signals to be regenerate by a band pass filter 13 and an amplitude detector 14 detects the amplitude the modulation sensitivity detection signal. A modulation sensitivity controller 9 uses a comparison controller 16 to compare the amplitude of the modulation sensitivity detection signal obtained from the modulation sensitivity detector 8 with a reference signal of a reference signal generator 15 to decrease the gain of the variable gain amplifier 2 when the modulation sensitivity of the voltage controlled oscillator 4 is increased and to increase the gain when the modulation sensitivity is decreased. Thus, the dispersion or fluctuation of the modulation sensitivity of the voltage controlled oscillator is corrected.
