    摘要： An electronic ballast for a high intensity discharge lamp (HID) includes a power converters, a controller, and a lamp power switch. In the power converter, an input DC voltage is converted into a ballast output power for lighting the HID lamp. The controller has a function to control the power converter and change the ballast output power. The lamp power switch detects a lamp output parameter indicated after the HID lamp starts discharge, identifies a lamp power of the HID lamp according to the lamp output parameter, and gives an identification signal indicating the lamp power. In response to this identification signal, the power converter outputs the ballast output power which matches with the lamp power identified.

    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 vehicle seat is provided with: a rotation lock mechanism for inhibiting or permitting rotation of the both support arms placed at a fixed position relative to base frames and a support arm operation mechanism for actuating the rotation lock mechanism by tilting of a backrest. In the vehicle seat, when the backrest is tilted forward beyond a maximum forward adjustment angle of a reclining angle range, the rotation of the both support arms from the fixed position is permitted. When the backrest is tilted further backward than the maximum forward adjustment angle, the rotation of the both support arms from the fixed position is inhibited.
