Title: Emphasis circuit and de-emphasis circuit
Inventor: HIYAMA TAKASHI
IPC: H04N5/92
Filed: 1993-02-23
Abstract: PURPOSE:To improve deterioration in the signal by applying horizontal emphasis or de-emphasis processing only to a high frequency component of a video signal so as to suppress disturbance of a harmonic component of a low frequency component onto a high frequency portion. CONSTITUTION:A sampling video signal Sr1 passes through an HPF 1 to obtain a high frequency component Sr2 and a time inversion linear phase high pass filter 2 is used to generate a high frequency component Sr7 emphasizing a high frequency component. The component Sr7 is given to a nonlinear limiter circuit 8, in which the amplitude is limited and the harmonic component caused by the nonlinear characteristic is given to the HPF 9, from which a high frequency component Sr9 in which the harmonic component is eliminated is obtained. Then the component Sr1 is delayed by a predetermined time at a delay circuit 10 and a resulting video signal Sr10 and the high frequency component Sr9 are added by an adder circuit 11 to obtain the video signal Sr11 whose high frequency is emphasized. The signal is subjected to prescribed de-emphasis processing and demodulated, then the disturbance of the harmonic component of the low frequency component of the video signal is suppressed and the SNR is improved.

Title: Overcurrent protective circuit for brushless motor
Inventor: TAKEDA MASAHIRO
IPC: H02P6/12
Filed: 1990-02-14
Abstract: PURPOSE:To enhance a circuit efficiency and to prevent an erroneous operation due to switching noise by providing breaking means for turning OFF between the drain and the source of a field effect transistor when an overcurrent is detected. CONSTITUTION:When a current flowing between the drain and the source of an FET 6 becomes an overcurrent, a voltage V2 output from an amplifier 4 becomes a set voltage V1. Accordingly, a comparator 3 applies an H signal to a NOT circuit 82. In this case, since the circuit 82 applies an L signal to an AND circuit 81, the circuit 81 inhibits to input a signal from a distributor 2 to the gate of the FET 6. When no H signal is input to the gate of the FET 6, the FET 6 is turned OFF to break a power source to a driving coil 7.

Title: Optical disc
Inventor: ODA TORU
IPC: G11B7/24073
Filed: 1985-02-21
Abstract: PURPOSE:To increase the capacity and density of recording as well as prevent crosstalk by forming light beam guide grooves respectively in the convex track and the concave track and performing tracking about the both tracks by said guide grooves. CONSTITUTION:When a laser light beam 4 is incident on a light beam guide groove 2 with a optical axis 4A normal to the center M of the groove, light is scattered by surfaces exactly mirror image with respect to the optical axis 4A, and each of the right and left halved light detector receives exactly equal amount of light, giving a mirror image curve with respect to the optical axis 4A as shown by curve QR. When the laser beam 4 is incident with its optical axis 4A at the bank A of the groove 2, scattered light is distributed asymmetric with respect to the optical axis 4A, and the right and left halved light detectors receive unequal amount of light, giving a curve PQ. This difference in amount of light received by the halved light detector due to misalignment of the optical axis with the center of the light beam guide groove 2 is fed as the tracking signal for the servo-control.

Filed: 1982-03-05
Abstract: PURPOSE:To prevent the flow of unnecessary inrush currents and control currents by selecting the value of the output voltage of a DC-DC converting circuit in value close to the peak value of motor induced voltage and restarting the motor when restarting it after service interruption is returned. CONSTITUTION:When service interruption is returned, the induced voltage of the motor is detected by a detector 5, and the frequency of an inverter in case of restart is set to value equal to the frequency of induced voltage by an arithmetical command circuit 8. The peak value of induced voltage is arithmetically operated from the frequency of induced voltage detected in the output frequency voltage arithmetical command circuit 8, and a voltage command is emitted so that the output DC voltage of a DC-DC converter is equalized to the peak value of induced voltage arithmetically operated. Accordingly, the motor can be restarted and accelerated smoothly without flowing unnecessary inrush currents and control currents when restarting it by restarting a power supply device while using the frequency and voltage as command values.

The complex amplitude distribution of an image to be reproduced is calculated, and an average value of error is calculated in accordance with an amplitude component t'(ak) of the image at the signal sample point and the designated value S(ak), and the latest sequence of phase components obtained in the step B is defined as a phase sequence to be recorded if the calculated value is in an allowable range. If it is on the outside of the allowable range, the amplitude component t'(ak) is substituted with the designated value S(ak), and the control is returned to the step B.

With such a constitution, the clock signal and the data signal are cancelled in the sound signal added and fetched, so that sound is favorably listened. Then, the data signal is recorded with a simple constitution and the interchangeability with other devices is obtained.

Abstract: PURPOSE:To conduct highly accurate level measuring with noise effectively excluded by providing a synchronous rectification circuit and a low pass filter on a receiving circuit to make a frequency of a synchronous signal conformable with that of an ultrasonic wave to be transmitted. CONSTITUTION:A synchronous rectification circuit 10 and a low pass filter 11 connected to its output side are provided on a receiving circuit of a receiver, an output side of the low pass filter 11 is connected to a control device 2, and a frequency of a synchronous signal of the synchronous rectification circuit 10 is made conformable with that of an ultrasonic wave transmitted from the receiver. When a reflected signal is received and inputted in the synchronous rectification circuit 10, since the inputted signal frequency is conformable with the synchronous signal frequency, a negative half-wave is rectified to be inverted between positive half-waves. This causes the output of a synchronous rectification signal in which the positive half-wave appears in a frequency two times that of the input signal. The synchronous rectification signal is envelope-detected by passing the next low pass filter 11, and an resultant envelope signal is outputted to the control device 2.
