  • Patent number: 5578862
    Abstract: By reverse biasing the PN junction formed around a semiconductor element, the semiconductor element is isolated from other elements. The PN junction around the semiconductor element is a junction between a layer surrounding the semiconductor element and a layer disposed outside the layer. Jointly with the layer constituting the semiconductor, the layer surrounding the semiconductor element forms a parasitic diode. The potential of the layer on the semiconductor element to be connected to the layer surrounding the semiconductor element is detected, and based on this potential, the voltage to be applied to the parasitic diode is controlled so as to be constant. When the voltage to be applied to the parasitic diode is lower than a threshold, the parasitic diode will be in a cutoff state.

  • Patent number: 5243474
    Abstract: An automatic tracking control system with a servo loop, controlled by a tracking control signal, that adjusts the position of a pickup head in relation to tracks scanned by the head. Adjacent-track crosstalk is extracted by a crosstalk detector and envelope-detected by a crosstalk envelope detector. An automatic tracking control circuit varies the tracking control signal, finds a state that minimizes the crosstalk envelope, and maintains the tracking control signal at or near that state.For double-deck recording systems in which one signal is recorded in surface tracks over another signal, the automatic tracking control circuit seeks a best compromise between minimizing the crosstalk envelope of one of the signals while maximizing the envelope of the other signal.

  • Patent number: 5223992
    Abstract: A rotary magnetic head device in a magnetic recording and reproducing apparatus such as a VTR apparatus and a DAT apparatus which adopts a helical scanning system. In order to prevent the demagnetization of a magnetic tape and reduce a jitter component of a reproducing signal, a head unit moves the magnetic head in the diametrical direction of a rotary drum. The head unit has a bobbin inserted into the center holes of a plurality of spring leaves, and the bobbin is moved in the diametrical direction of the rotary drum by the electromagnetic force produced on the coil wound around the bobbin. A head arm attached to the spring leaf is thereby moved in the same direction, thereby varying the amount of projection of the magnetic head. The amount of projection of the magnetic head is controlled in correspondence with the level of the envelope of a reproducing signal so as to be set at the minimum value in the range in which the output level of the envelope signal is saturated.

  • Patent number: 5182683
    Abstract: A magnetic recording and reproducing apparatus for reproducing information from a track recorded on a magnetic tape made to travel by being driven by a capstan. Even if a track has been recorded in a curved form, a magnetic head is displaced substantially perpendicularly to a rotational axis of a rotating drum in correspondence with the curve so as to trace the track. A signal read from the track by the magnetic head is subjected to envelope detection and is converted to a digital envelope signal. The capstan is driven and controlled such that the intensity of the digital envelope signal becomes substantially maximum.

  • Patent number: 5101309
    Abstract: While prior art apparatus for magnetic recording and playback (VTRs) were unable to perform magnetic recording of an FM signal with an optimum recording current responding to change of the optimum recording current dependent on kinds of magnetic tapes used and wear of heads, the magnetic recording of an FM signal with the optimum recording current at all times has been made possible by having a recorded signal along a track of a magnetic tape read by a level servo head scanning the track following the signal recording and having the recording current controlled to be optimized by use of a recording current controlling device based on the playback signal output from the level servo head. As a result, improvement of the S/N ratio and automatic adjustment of the recording current can be achieved. Further, by means of a head drive unit, the position of the level servo head is finely adjusted so that the control for optimization of the recording current is performed accurately.

  • Patent number: 5060078
    Abstract: A video signal processing apparatus which is adapted to a VTR (video tape recorder) and various other video players for processing a video signal so as to reduce noise. A video signal passed through a demodulator and a deemphasis circuit is input to a noise canceller circuit so as to remove most of the noise component thereof. The video signal is then provided with narrow and deep peaks at the respective rising transient portion and the breaking transient portion with bipolarity by an outline emphasizing circuit. Thus, smooth signal processing of the group delay characteristic is enabled in a wide frequency band, thereby producing a video signal having excellent sharpness and not including a strain such as overshoot or ringing.
