Title: Lighting controller for car head lamp
Inventor: KATO YUJI
IPC: B60Q1/04
Filed: 1987-10-06
Abstract: PURPOSE:To keep off any dazzling light against a facing car by forming head lamps in series or parallel to a power source, while installing such a device that commands a storage or open position of the said lamps, and forming a series lighting circuit at the time of the open position. CONSTITUTION:Head lamps LH, RH are commanded into series connection by a light switching device 1 simultaneously with a command to an open position. If so, a series lighting circuit 201 is formed by a lighting control device 300 in response to a fact that these lamps LH, RH are moved up to the open position, and thereby it is electrically connected out of a battery BT. With this power supply, the head lamps are dimmed. And, when either of these head lamps are locked in the point midway in operation from a storage position to an open position, the lighting control circuit 300 will not form the series lighting circuit 201. In consequence, when one side head lamp is locked, they are not lighted for dipping, thus dazzling light against a facing car is prevented from lighting on.

Abstract: PURPOSE:To record at appropriate recording density even after discharge restoration treatment, by a method wherein a heat controlling device increasing energy of a driving signal per unit time to be fed to a heating device in the case where discharge restoration treatment is performed by a discharge restoration device is provided. CONSTITUTION:An environmental temperature is detected by a temperature sensor and then existence of discharge restoration treatment is detected. But for the discharge restoration treatment, electrification duty is decided on reference to a table which has been stored based on the detected environmental temperature and a heat insulation heater is electrified at corresponding pulse widths or intervals. When the discharge restoration treatment is in existence, a timer measuring a lapse time is reset and electrification duty having higher energy than ordinary electrification duty is decided on reference to the table which has been stored based on the environmental temperature. The heat insulation heater is electrified at pulse widths or intervals corresponding to the decided electrification duty and this electrification is kept on until the lapse of a fixed time. In addition, in the case where the discharge restoration treatment is based on instructions of a user, the same is performed at the time of the first recording when the recording has not been performed for at least three days.
