摘要： A coordinate input system to which control data (a displacement value), concerning the location and the posture of a displayed graphic object, can be input with a conventional coordinate pointing device, such as a mouse, and a method therefor. Coordinate values of three sequential input points P.sub.n, P.sub.n+1 and P.sub.n+2, which are entered with a coordinate pointing device, such as a mouse, are employed to calculate the central angle .angle.P.sub.n O.sub.n P.sub.n+2 relative to the arc P.sub.n P.sub.n+1 P.sub.n+2 of the circle O.sub.n circumscribed about these three points. Then, the angle .angle.P.sub.n O.sub.n P.sub.n+2 is employed to acquire the central angle .angle..theta..sub.n for the arc P.sub.n P.sub.n+1. A logic circuit or an upper-level program that waits for the input of the dial rotation value as control data employs the central angle .angle..theta..sub.n, which is acquired by inputting the coordinate values of the two sequential points P.sub.n and P.sub.n+1, to rotate a graphic model around a designated axis on a screen in accordance with the angle .angle..theta..sub.n.

摘要： An electronic ballast for hot cathode discharge lamp comprises a DC voltage source, a chopper, and an inverter. The chopper includes a switching element connected in series with an inductor across the DC voltage and driven to turn on and off for providing a periodically interrupted voltage which is smoothed by a capacitor to produce a smoothed DC voltage as a chopper output. The inverter includes at least one switching element which is coupled to the chopper output to produce therefrom a high frequency AC voltage as an inverter output to be applied to cathodes of the discharge lamp for lighting the discharge lamp. The ballast is characterized to include an inverter controller and a delay circuit. The inverter controller controls the inverter to operate selectively in a normal mode of providing the inverter output of a first level and in a limited mode of providing the inverter output of a second level which is lower than the first level and is determined to give a preheating current to the cathodes. The delay circuit delays the start-up of the inverter for a time period from the start-up of the chopper. The inverter controller controls the inverter to operate in the limited mode after the start-up of the inverter for a predetermined period for preheating the discharge lamp after which the inverter controller allows the inverter to operate in the normal operation mode for lighting the discharge lamp.

摘要： A power supply for driving one or more loads includes a DC voltage source, an inverter connected to the DC voltage source for providing a high frequency AC voltage at its output end, and an output transformer having a primary winding and a secondary winding. The primary winding is coupled to the output end of the inverter through a tuning inductor, while the secondary winding is coupled to the load. A tuning capacitor, which constitutes a resonant circuit in cooperation with the resonance inductance for supplying a resonance current to the load, is connected across the secondary winding of the output transformer in parallel relation to the load. The tuning capacitor is arranged in circuit on the opposite side of the secondary winding from the load such that the tuning capacitor is open-circuited when the load is disconnected from the secondary winding.

摘要： A power supply with an inverter capable of avoiding the inverter from producing excessive high voltage when a load is detached or the load impedance is greatly increased. The inverter is energized by a fixed DC voltage source and includes at least one switching element and an L-C resonant circuit. The switching element is driven to turn on and off and cooperative with the L-C resonant circuit to produce a high frequency AC voltage at an inverter output for driving a load. The inverter includes first and second clamping diodes connected in series across the DC voltage source in anti-parallel relation thereto with the first and second diodes defining therebetween a first connection point. Also included in the inverter is a pair of first and second impedance elements which are connected in series across the inverter output to provide a divided voltage indicative of an output voltage of the inverter with the first and second impedance elements defining therebetween a second connection point. The first and second connection points are connected to each other so as to keep the points at a voltage level nearly equal to a fixed voltage of the DC voltage source, in such a manner as to limit the output voltage of the inverter below a predetermined level by allowing a clamping current to flow through the first and second diodes and impedance elements and through the DC voltage source to escape the excessive voltage developed in response to the increase in the impedance of the load.
