  • Video tape recorder
    Patent number: 4492994
    Abstract: A video tape recorder comprises a loading disc, a supply reel mount and a take-up reel mount, a reel mount driving device to be selectively associated with the supply reel mount and the take-up reel mount to establish recording, playback, rewinding, fast-forward, and stop modes, and a mode switching device for selectively transmitting the rotatory force of the motor to the loading disc and the reel mount driving device so that the loading disc is rotated when the rotatory force is transmitted to the loading disc, and that the reel mount driving device is set to a selected one of said modes when the rotatory force is transmitted to the reel mount driving device.

  • Apparatus for driving pulse motors for automatically adjusting external circuits
    Patent number: 4384334
    Abstract: A plurality of pulse motors (225X, 225Y, 225Z) can rotate driver devices (222X, 222Y, 222Z). The driver devices are fitted in the parts of, for example, a horizontal oscillation circuit, a vertical output circuit and a power source circuit of a television circuit, which are formed on a printed circuit board (220). The outputs of the horizontal oscillation circuit, vertical output circuit and power source circuit are supplied to a digital frequency counter (223X), a first digital voltmeter (223Y) for measuring vertical amplitude and a second digital voltmeter (223Z) for measuring power source voltage, respectively. They are converted into digital data.The output data of the digital frequency counter (223X), the first digital voltmeter (223Y) and the second digital voltmeter (223Z) are compared with predetermined data at digital comparators (224X, 224Y, 224Z), respectively.

  • Automatic testing apparatus for automatically testing a printed circuit board
    Patent number: 4348276
    Abstract: A printed circuit board (OS) with a circuit for use in a television receiver is carried to a location of a conveyor (OD) for testing process. A printed circuit board takeout device (OB), automatic parts testing device (OF), first sorting device (OG), first automatic parts measuring/adjustment device (OI), second sorting device (OJ), second automatic parts measuring/adjustment device (OK), third sorting device (OL) etc. are sequentially arranged on a path of conveyance of the printed circuit board on the conveyor (OD). The automatic parts testing device (OF) is adapted to test whether or not a component part of a desired value exists in a desired location of the printed circuit board (OS). The first sorting device (OG) is adapted to transfer an unfit printed circuit board to a conveyor (OH) for unfit printed circuit board.
