摘要： A power source device is so arranged that one of switching elements forming a plurality of power conversion switching circuits which is used in common during each switching cycle is made to have a switching period in which mainly a current is taken up from a power source of first one of the switching circuits, the switching period being varied in a zone in which an input voltage is higher than a predetermined voltage in a cycle of input voltage waveform. Any distortion of input current waveform occurring around lower voltage period of commercial AC source is thereby reduced, in the power source device wherein the power conversion switching circuits employ commonly the switching elements.

摘要： A discharge lamp lighting device which comprises a D.C. power supply, a load resonance circuit including an inductor, a capacitor and a discharge lamp; a polarity inverting circuit including at least a series circuit of first and second switching elements connected in parallel to the D.C. power supply for converting a D.C. power received from the D.C. power supply into an A.C. power to supply it to the load resonance circuit; and a control circuit for turning ON and OFF the switching elements alternately at a high frequency to alternately generate a first period during which an ON duration of the second switching element is longer than that of the first switching element and a second period during which the ON duration of the second switching element is shorter than that of the first switching element, to thereby apply a rectangular-shaped low frequency voltage to the discharge lamp. The control circuit superimposes a D.C. component in an output of the polarity inverting circuit upon a resonance pulse signal from the load resonance circuit to continuously change a switching frequency of the switching elements for the predetermined time from the start time point of one of the first and second periods, and supplies to the discharge lamp a first energy necessary for starting and lighting the discharge lamp with a high pulse voltage obtained through LC resonance and also for smoothly shifting the lamp to an arc discharge state.

摘要： A device for determining position coordinates of points on a surface, has a tablet containing plural number of equally spaced driver windings and plural number of equally spaced sense windings. Each driver winding has a pair of parallel conductors laid in X-direction, and each sense winding has a pair of parallel conductors laid in Y-direction. A current is generated in a cursor coil by the voltage induced from the current in a nearby situated driver winding. This current in the cursor coil induces a voltage in a nearby situated sense winding. The X-position of a sense winding in which a maximum voltage is induced, and the Y-position of a driver winding which induces a maximum voltage in the cursor coil, determine the position coordinates of the cursor on the tablet. Auxiliary sense windings are supplemented to the tablet. Induced voltages on these auxiliary sense windings determine the Y-position of the cursor regardless of its X-position, and reduce the overall time required for position determination.
