Abstract: PROBLEM TO BE SOLVED: To keep a surface of a dirt preventive blind in a clean condition by arranging a surface layer in which both of a part having hydrophilic property of optical catalytic oxide particle and a part having water repellency of water repellent fluororesin are dispersed therein. SOLUTION: A coating component in which an optical catalytic particle, water repellent fluororesin, water, solvent such as ethanol, crosslinking agent of fluororesin, and surface active agent are mixed is applied on a surface of a basic material. In this case, it is coated by a method such as spray coating, dip coating, coating by using a brush, and coating by using a sponge. Furthermore, it is fixed by a method such as heat treatment of fluororesin at a temperature above melting temperature, heat treatment and pressurization treatment of fluororesin at a hardening temperature by using crosslinking agent, and fixation by using impact pressure. Anatase-type titanium oxide is used in optical catalytic oxide and polytetrafluoroethylene is used in water repellent fluororesin. Moreover, the thickness of a film of a surface layer is reduced to prevent coloring of the surface layer due to the interference of light and improve wear resistance of the surface layer.

Title: Lighting equipment for discharge lamp and lighting equipment in discharge lamp
Inventor: NOBUHARA MOCHIKIYO
IPC: H02M7/06
Filed: 1997-11-05
Abstract: PROBLEM TO BE SOLVED: To enable a starting control with a simple circuit, by detecting an operating conditions of a discharge lamp sensing the output status of an inverter, and by reducing the output of a booster chopper when discharge lamp does not turn on properly. SOLUTION: When a fluorescent lamp does not turn on normally, an inverter circuit 5 becomes inductive load, and the voltage at the secondary winding of a transformer T2 decreases due to a load current decrease. Then, an output of a voltage double rectifier circuit 8a decreases and a Zener diode ZD83 becomes OFF and a transistor Q83 is turned on. When the output voltage of the rectifier 8a exceeds a given value, a transistor QCP is turned off and a chopper circuit 4 stops its boost operation, and the input voltage to the inverter circuit 5 decreases. In this process, when no-load and a short-circuit state are detected, a chopper output control circuit 8 reduces the output of the chopper circuit 4 by changing a switching frequency or on-duty ratio of the transistor QCP which carries out the chopper operation.
