Title: Discharge lamp lighting device and lighting system
Inventor: KONNO HIROYUKI
IPC: H05B41/392
Filed: 1996-03-28
Abstract: PROBLEM TO BE SOLVED: To easily control and change the color temperature and color rendering property of a discharge lamp being turned on. SOLUTION: A switching control circuit 3 controls transistors Tr1, Tr2 to turn them on and off alternately to produce a high-frequency current, which is converted to high voltage by a resonance circuit consisting of coils L1, L2 and a capacitor C3 and which is then made to flow to the discharge lamp 4 to light the lamp. When a volume VR is changed, a reference voltage for comparison with a voltage corresponding to the current flowing through the transistor Tr2 and detected by a current detecting transformer 6 is changed. Therefore, the timing that the current flowing through the transistor Tr2 is converted to the reference voltage is shifted, and the timing that the transistor Tr2 is switched off by the switching control circuit 3 is also shifted, changing the on-duty period of the transistor Tr2. Therefore, the crest factor of the high frequency current flowing through the discharge lamp 4 is changed, resulting in changes in the color temperature and color rendering property of the discharge lamp 4.

Title: Air ventilation apparatus for underground room

IPC: F24F7/06
Filed: 1983-04-28
Abstract: PURPOSE:To enable to introduce atmospheric air stable in temperature and moisture into an underground room by providing a dew condensation regulating cylinder at a section which passes through the outer wall of the room. CONSTITUTION:Air fed by an axial flow fan 7 which is mounted out of the ground surface is fed via a branch tube 6 into a guide pipe 4, through a dew condensation regulating cylinder 13, and diffused from the inner bottom of an underground room 1. In this case, the air approaches the underground temperature in the environment while passing through a copper guide pipe 4 which extends over a considerably long distance in the soil of constant temperature state to be cooled in summer, and heated in winter. When the atmospheric air containing moisture passes the cylinder 13, the air becomes a saturated state to condense dew on the wall of the pipe 4 and the wall of an inner copper pipe 12 to reduce the moisture. When this air is diffused into the room 1, the temperature in the room 1 is higher than the underground temperature, and the air is accordingly reheated and dried. The dew condensated water in the cylinder 13 is dropped to the inner bottom of the room 1 from a hole of the cylinder 12, but a drain bush 14 mounted on the outer periphery receives the returning droplet to drop together on a droplet receiving slot 20 provided directly thereunder.
