Abstract: An output of a rectifying circuit (6), which rectifies commercial AC power, is supplied to an inverter (12) through a power factor correction circuit (8). The output of the inverter (12) is voltage-transformed in a transformer (16), rectified in a rectifying circuit (18) and is applied to a xenon lamp (2). A secondary winding (22s) of a transformer (22) of an igniter (20) is connected between the rectifying circuit (18) and the xenon lamp (2) in order to generate an arc in the xenon lamp (2). A pulse generator provides a pulse for a short time period to a primary winding (22p) of the transformer (22). An auxiliary power supply (26) supplies arc-sustaining current prepared based on the commercial AC power to the junction of the rectifying circuit (18) and the secondary winding (22s) of the transformer (22).

Abstract: A power supply apparatus for a light source includes an input-side rectifier (32) which converts an input AC signal to a DC signal, and a high-frequency inverter (36) which converts the DC signal to a high-frequency signal. An output-side rectifier (42) converts the high-frequency signal to a DC output signal for application to the light source. Power detecting means (52) detects the power supplied to the light source through the application of the DC output signal thereto, and develops a power representative signal. A control circuit (38), a summer (54) and an error amplifier (58) cooperate to control the high-frequency inverter (36) in accordance with the power representative signal in such a manner that power of a predetermined value can be supplied to the light source. An input current detector (60) detects the input AC signal current value and develops an input current representative signal.

Abstract: A blood-collection position indicator facilitating blood collection is provided. An adhesive layer is positioned on the back face of a substrate portion having a convex cross section and a circular planar shape, and at its center, a through hole going through the substrate portion and the adhesive layer is provided to serve as a blood collection hole, thus obtaining a blood-collection position indicator. In the blood-collection position indicator, the protruding portion serves as an attachment part to be attached to the tip of a lancet device, and the protruding portion is inserted into a hole of the tip of the lancet device, thus attaching the blood-collection position indicator to the tip of the lancet device. Adhesive strength of the adhesive layer to the skin is set to be stronger than attachment strength of the attachment part to the tip of the lancet device. Consequently, only the first blood-collection position indicator remains on the skin after the lancet device is used.

Abstract: A power supply apparatus useful for starting and driving a discharge lamp 22 includes a DC-to-DC converter 16 for converting a DC signal from a DC power supply to a second DC signal having a predetermined magnitude which is supplied to the lamp. A current detector 24 develops a DC current representative signal representing DC current supplied to the lamp from the DC-to-DC converter. A combination of the current detector 24, a DC voltage detector 26 and a multiplier 30 develops a DC power representative signal representing DC power supplied from the DC-to-DC converter to the lamp. An error amplifier 32 develops a DC current error signal representing the difference between the DC current representative signal and a predetermined DC current reference signal. An error amplifier 36 develops a DC power error signal representing the difference between the DC power representative signal and a predetermined power reference signal.
