摘要： A control circuit for an H-bridge circuit comprises a single capacitor, a charge/discharge circuit for charging/discharging the capacitor in response to a control command signal, a voltage detector circuit for detecting a voltage appearing across the capacitor and a hold circuit for holding the control command signal in response to of a predetermined voltage detected by the voltage detection circuit. Charge and discharge of the capacitor is controlled in dependence on changes in the control command signal to thereby prevent occurrence of a through-current flow in the H-bridge circuit while allowing the bridge circuit to be changed over to the operation state indicated by the control command signal after lapse of charge/discharge period. The control circuit for the H-bridge circuit can be implemented in a miniaturized size with high reliability of operation while decreasing the number of elements attached externally even in the case where the control circuit is implemented in the form of an integrated circuit.

摘要： A light source device that irradiates a discharge vessel with a laser beam to produce radiant light that is reflected by an ellipsoidal reflecting surface efficiently utilizes the light produced by directing the laser beam through an unirradiated region where reflected light from the ellipsoidal reflector is blocked by the discharge vessel, through an opening side of the ellipsoidal reflector to the discharge vessel. The discharge vessel has an emission substance enclosed inside which is excited by the laser beam and produces radiant light, is arranged at a focal point of the ellipsoidal reflector. A planar mirror, with which radiant light reflected by the ellipsoidal reflector is reflected in a different direction has a window in an unirradiated region where reflected light from the ellipsoidal reflector is blocked by the discharge vessel through which the laser beam passes to the discharge vessel.

摘要： An object is to reduce the offset voltage between the input and output in a wide range of output current with a simple circuit configuration. Transistors (Q1), (Q2) and (Q3) have a size ratio of m:n:1, transistors (Q6) and (Q7) have a size ratio of 1:p, and transistors (Q4) and (Q5) have a size ratio of {(m+n+1)/p:}). Accordingly a current which is (m+n+1) times the current flowing in the transistor (Q3) is supplied to the emitter electrodes of the transistors (Q1) and (Q2). Since the ratio between the currents flowing in the transistors (Q1) and (Q2) is the same as their size ratio m:n, the emitter-base voltages are equal between the transistors (Q1) and (Q2). As a result, the offset voltage between the voltage signal inputted to the input signal line (IN) and the voltage signal outputted from the output signal line (OUT) can be suppressed in a wide range of output current.
