摘要： A pulse width modulated signal amplifier comprises a DC power supply for rectifying an AC input voltage to produce a pair of DC voltages of opposite polarity, a pulse width modulated signal amplifying circuit supplied with a pulse width modulated signal to produce a demodulated signal through a low pass filter, and a detecting circuit responsive to an abnormal level of the DC voltages to produce a detecting signal when a smoothing condenser of the DC power supply is overcharged by a current flowing through the low pass filter in one direction. Such detecting signal is desirably employed to prevent the appearance of the output signal from the pulse width modulated amplifying circuit.

摘要： A transistor amplifier including a bipolar transistor supplied with an input signal and a field effect transistor which is directly connected to an output electrode of the bipolar transistor to amplify a signal applied thereto. The transistor amplifier has a protective circuit which senses the load impedance and actuates a protective means across an input terminal of the transistor amplifier when the sensed load impedance is lower than a predetermined value. Accordingly, the transistor amplifier is protected against overload conditions.

摘要： A transistor inverter includes at least a pair of switching transistors, a transformer with primary and secondary windings, a DC voltage source with a pair of output terminals and a voltage reference terminal, and a rectifying circuit connected to the secondary winding of the transformer. A collector electrode of one of the switching transistors is insulated from a chassis by an insulation means comprising a first insulating layer, a conductive layer such as a heat sink and a second insulating layer. The conductive layer is electrically connected to the voltage reference terminal of the DC voltage source so as not to produce an undesirable radiation through the chassis.

The radio frequency circuit board includes first and second radio frequency transmission and reception circuits at both end portions, respectively. The radio frequency circuit board includes a second earth plate serving as a grounding electric potential of the radio frequency transmission and reception circuits. Feed lines from the radio frequency transmission and reception circuits are connected to the first earth plate, respectively. Ground lines of the feed from the radio frequency transmission and reception circuits, respectively, are connected to the second earth plate. Thus, vertical exciting currents flow at both end portions of the second earth plane, enabling transmission and reception of vertical polarization waves.

摘要： Binary information previously recorded in an innermost rim side area is enabled to be stably reproduced. A record medium is formed by sequentially laminating a first information layer 2, an intermediate layer 3, a second information layer 4, and a cover layer 5 onto a substrate 1. First grooves are previously formed in the innermost rim area of the substrate 1. Second grooves are previously formed in an area where data is recorded. The first grooves are set to be shallower and narrower than the second grooves. Thus, such a situation that a BCA signal is modulated by diffraction due to the grooves can be reduced.

摘要： Audio-centered information is stored on a unitary medium by using a Table-of-Contents (TOC) mechanism that specifies an actual configuration of various audio items on the medium. In particular, each one of a set of one or more Track Areas gets at least two mutually logically conforming Sub-TOCs assigned. This allows to retrieve any constituent Sub-TOC part from at least any correct copy of the Sub-TOCs. Furthermore, one or more Master-TOCs are provided for specifically pointing to each of the Sub-TOCs.
