    • An automatic guided vehicle having three wheels consisting a front wheel and a pair of rear wheels and being capable of travelling along a track formed on a floor by a white line or aluminum foil while detecting the track by means of an optical type track sensor. The front wheel of this vehicle can be turned relative to a main body of the vehicle in response to a steering operation and can be locked in the lateral direction. The position of the pair of rear wheels can be symmetrically changed from a paralleled state to an orthogonal state relative to the center line of the main body to be maintained in these states, thereby enabling the main body to turn or laterally travel with radii of gyration determined in accordance with turning angles of the rear wheels relative to the main body on the basis of the relative turning and driving operations of the front and rear wheels.

    • An isolated converter with a reduced size is disclosed. A small-sized multilayer sheet transformer includes a multilayer circuit board composed of a plurality of sheet substrates, coil patterns of primary and secondary coils disposed coaxially on the sheet substrates, and a core member disposed in a coil pattern unit formed of the coil patterns. In this multilayer sheet transformer, a coil pattern formed on the outer surface of the top layer and a coil pattern formed on the outer surface of the bottom layer are for the same coil on either the primary or secondary side. In the case where the coil patterns formed on the outer surfaces of the top and bottom layers of the multilayer sheet transformer are for the primary coil, an isolation gap is formed between the multilayer sheet transformer and a circuit on the secondary side to prevent an electrical breakdown between the primary and secondary sides. In the case where the coil patterns formed on the outer surfaces of the top and bottom layers of the multilayer sheet transformer are for the secondary coil, an isolation gap is formed between the multilayer sheet transformer and a circuit on the primary side to prevent an electrical breakdown between the primary and secondary sides.

    • A speech detection circuit includes an amplifier for amplifying an input audio signal and having a variable gain, a rectifying circuit for rectifying an output signal of the amplifier, a comparator for comparing an output signal level of the rectifying circuit with a reference level, and a control circuit for outputting a control signal based on an output signal of the comparator. The control circuit outputs a control signal which indicates a power save mode after a predetermined time elapses from a time when the output signal level of the rectifying circuit becomes less than or equal to the reference level, and outputs a control signal which indicates a normal mode immediately when the output signal level of the rectifying circuit becomes greater than the reference level. The amplifier receives the control signal output from the control circuit and reduces its gain when the control signal indicates the power save mode.
