Abstract: PURPOSE:To select a time till sound volume or sound quality or the like is changed after a revision control instruction is received to be a half wavelength of an input audio signal by connecting one input of an exclusive OR to a data output of a delay circuit, and connecting the output of the exclusive OR to the storage control input of a register. CONSTITUTION:A delay circuit 6 and an exclusive OR 7 are provided, even when an input audio signal changes from a negative potential to a positive potential, to obtain a storage control signal by which a register 2 supplying a logic data C to a control circuit 5 is able to store a logic data surely. That is, a logic level being the output of a voltage comparator 3d detecting a zero level at the moment when a revision control instruction (b) is issued and a logic level delayed by a delay circuit 6 are exclusively ORed (7) to supply a storage control signal to the register 2 provides a logic data C to the control circuit 5 when a logic level being an output of the voltage comparator 3d is first inverted after the revision control instruction 6 is given. Thus, the time when sound volume or tone quality or the like is revised after receiving the revision controlinstruction is set to be within a half wavelength of the input audio signal.

Title: White balance time lapse compensation circuit
Inventor: OTAKE KEIICHI
IPC: H04N9/73
Filed: 1990-11-30
Abstract: PURPOSE:To always express a beautiful video by providing a video signal adjusting circuit which controls the amplitude of a video signal for R. G, and B, respectively corresponding to the amount of current that flows in a beam draw-out electrode, and always keeping white balance. CONSTITUTION:A terminal VG is connected to the beam draw-out electrode, and the voltage value of the terminal is decided by resistors R1, R2. When the current that flows on the terminal VG is decreased due to the lapse of time, the current on a transistor TR1 is decreased, and a voltage value E1 is increased. Thereby, since a transistor TR2 forms an inversion amplifier, a voltage value E2 is decreased. The voltage value E1 is added by resistors R6, R7 and a variable resistor VR1, which decreases the voltage of the amplitude adjusting terminal RA of the video signal adjusting circuit 100. Therefore, the white balance can be always kept by decreasing the amplitude of the video signal R even when the luminance of a tube surface is decreased in proportion to video display accumulative time due to change in the lapse of time.

Abstract: PROBLEM TO BE SOLVED: To miniaturize a configuration, at the same time reduce leakage of magnetic flux toward outside, and prevent poor magnetic influence to the surroundings by accommodating an electromagnet and a permanent magnet that become an actuator in the space of a box-shaped floating body being opened downward.

Title: Magnetic recording and reproducing device
Inventor: KAGAWA TAKASHI
IPC: H04N9/78
Filed: 1994-12-30
Abstract: PURPOSE: To obtain the magnetic recording and reproducing device in which color drooping is prevented and the S/N is improved. CONSTITUTION: When no crosstalk is included in a chroma signal or its level is equal to or less than a noise level, since a head is seldom bridged over an adjacent track, the level of the crosstalk is less than the noise level. In this case, a switch SW 1 is thrown to the position of a limiter 20 to eliminate a non-correlation component of the chrominance signal. As a result, even when a feedback quantity is increased to improve the S/N, color drooping is not increased and the image quality is enhanced. On the other hand, when the crosstalk is included, since the signal is not given to the limiter 20, the switch SW 1 is thrown to the other position, then an output signal (feedback signal) from a BPF 2 is fed to an ATT 3 as it is.

Title: Blower for vehicle air-conditioner
Inventor: OSAWA HIROSHI
IPC: H02P6/08
Filed: 1993-12-07
Abstract: PURPOSE:To decide the locked state of motor positively regardless of the rotational speed by a constitution wherein the time required for making a decision is set long for low set value of rotational speed whereas set short for high set value of rotational speed. CONSTITUTION:A lock decision circuit 7 receives a DC voltage +V and the inverted output voltage RS is set low for high set rotational speed of a brushless motor M. During high speed rotation, the detection signal K has a short repetitive period and a low peak value. When the motor is locked, the level of detection signal increases to lower the level of a current control signal L in a short time and a phase switching circuit 5 executes a predetermined current limiting operation. When the set rotational speed of the brushless motor M is low, the level of the inverted output voltage RS is set high and the detected output signal has a long repetitive period and a high peak value. When the motor is locked, the level of detected output signal increases and the level of current control signal L lowers gradually. This constitution allows positive decision of the locked state of motor rotating at low speed or high speed.
