    摘要： An eyewear type viewer having left and right LCD panels for the left and right eyes is arranged so that both LCD panels are driven and controlled by a single LCD drive circuit and a single timing control circuit, to reduce the weight and cost of the viewer. The timing control circuit controls the timings of the left and right LCD panels synchronously by sending a common timing control signal to both of the left and right panels, or controls the left and right panels individually by producing a first timing control signal for the left panel and a second timing control signal for the right panel. The timing control circuit may include a comparator which receives a composite control signal composed of a first component representing a write/hold signal, and a second component representing a quasi vertical synchronizing signal, and which separates the write/hold signal from the quasi vertical synchronizing signal.

    摘要： A vocal sound can be erased by a simple arrangement. An audio reproducing apparatus in which a sum signal and a difference signal of left and right signals of a stereophonic signal are supplied thereto, a left signal and a right signal are obtained from the sum signal and the difference signal and the left signal and the right signal are respectively supplied to a left signal output terminal and a right signal output terminal includes switches (SW.sub.1 to SW.sub.4) for supplying the difference signal to the left and right signal output terminals (T.sub.L, T.sub.R) by switching the left and right signals.

    摘要： An apparatus reproduces an information signal modulating a carrier signal recorded on a magnetic tape. A portion of the signal being boosted in accordance with a characteristic of the information signal. The apparatus comprises a playback device for reproducing the information signal from the magnetic tape, a detector for detecting the levels of the portion of the signal and the rest of the signal respectively and comparing the levels with each other, and a judging circuit for judging the characteristics of the signal in accordance with the output of the detector.
