Title: Signal processing device
Inventor: MISUMI HIROYOSHI
IPC: H04N9/66
Filed: 1987-01-29
Abstract: PURPOSE:To process a signal having plural modulation axes by sequentially selecting the signals demodulated by a demodulation means which demodulates the signal to be modulated according to the modulation axes. CONSTITUTION:As for a chrominance signal separated in a luminance signal (Y)/color signal (C) separating device 1, plural signals whose phases are different from an original signal and a burst flag are generated in a phase shifter 4 and an amplifier 6 and they are selected by a selecting switch 5 to be inputted in a demodulator 3, then demodulated with chrominance subcarrier whose phase to the burst flag is 0 deg.. Therefore, the constitution of a demodulation system will do with one system and the plural signals whose phases are different can be demodulated in terms of time division. For example, the demodulation axis can be changed, so that the demodulation of not only R-Y and R-Y signals but also I and Q signals can be possible. The signal more than two color difference signals can be generated in one demodulator. Thus, the sequential signals demodulated from the signal to be modulated having plural modulation axes can be obtained.

Title: Waveform shaping circuit
Inventor: YAMAGUCHI TOSHIYUKI
IPC: H03K5/08
Filed: 1982-02-10
Abstract: PURPOSE:To convert the waveform of an input signal accurately, by using a voltage division circuit comprising resistors and a constant current source, and setting a threshold level lower or higher by a prescirbed DC voltage than the DC component voltage of the input signal at all times even if the DC component of the input signal in which an AC component is superimposed on the DC component. CONSTITUTION:A DC voltage V0 of a voltage signal V1 is changed, a level difference Vd is changed by a product of R3 and DELTAI0 by a change of a constant current from the constant current source I0 through the effect of the DC voltage change. Since the constant current source has the property substantially that a constant current flows even if the applied voltage is fluctuated, the change I0 in the constant current is very small with the change DELTAV0 in the DC component V0 at an input terminal T1', and the DELTAVd is suppressed very small. Thus, an accurate angular signal V2 is obtained without shifted rise and fall of a waveform V2 after wave form shaping.

IPC: B60T8/58
Filed: 1998-01-19
Abstract: PROBLEM TO BE SOLVED: To determine a turn state of a vehicle with certainty by computing radius of turning from speed difference between right and left wheels, a tread value, and vehicular speed, computing the centrifugal force from the radius of spinning, and determining the turning of the vehicle when the centrifugal force is more than the specified value. SOLUTION: When an automobile 1 curvingly runs in the direction of an arrow A, speeds V1 , V3 of left wheels 2a, 2b exceed speeds V2 , V4 of right wheels 2b, 3b due to difference of radii of spinning. That is, V1 -V2 =Δ1>0, V3 -V4 =6>=2>0. When the values Δ1 and Δ2 are both more than zero for a specified time or longer, their mean value is read in a computer for centrifugal force calculation. Speed of a vehicular body is estimated from an output of the wheel speed sensor to compute the radius of spinning. The centrifutal force is then computed. When the specified value or more of centrifugal force is applied for a specified time or longer, spinning of the vehicular body is determined.

Title: Semiconductor pulse laser device and its manufacture
Inventor: MATSUI YASUHIRO
IPC: H01S5/00
Filed: 1997-02-04
Abstract: PROBLEM TO BE SOLVED: To make passive mode synchronization to occur easily by providing a diffraction grating having a sampled grating structure in which recessing and projecting section forming areas and planar areas are repetitively formed at prescribed intervals in a Bragg reflecting mirror area. SOLUTION: When a current is supplied to a gain area 121 from a power source 131, the area 121 acts as a gain medium and makes the light amplification required for light emission and laser oscillation. A saturable absorbing area 122 causes passive mode synchronization when a reversely biased voltage is applied across the area 122 from another power source 132. In addition, a Bragg reflecting mirror area 123 works as a wavelength filter incorporated in a resonator, because the area 123 is provided with a diffraction grating 105a. Namely, the area 123 controls the oscillation wavelength and limits the oscillation wavelength area. Therefore, the passive mode synchronization can be made to occur easily by suppressing the influence of refractive index dispersion.
