Title: Discharge lamp lighting device
Inventor: KAWABATA KENJI
IPC: H05B41/232
Filed: 1987-10-30
Abstract: PURPOSE:To stably start a discharge lamp without a starting equipment by providing a smoothing capacitor and a current detector and lighting the discharge lamp when the voltage on the d.c terminal of the smoothing capacitor becomes highest. CONSTITUTION:A commercial a.c power source 1 is rectified through a rectification circuit 2 so as to generate a d.c voltage including a ripple voltage. The generated d.c voltage is applied to a smoothing capacitor 3 and a series circuit of a current detecting resistance 4 which detects a current iC flowing through the capacitor 3. When the direction of the current iC is reversed, that is, the terminal voltage of the capacitor 3 becomes highest, switching elements SW1 to SW4 are controlled to be opened/closed so as to switch the mode. The elements SW1 to SW4 charges/discharges the capacitor 5 on the preheat mode and preheats filaments 6a, 6b. Next, on the starting voltage generation mode due to the opening/closing control, the voltage twice the voltage 1 is applied to the discharge lamp 6 so that it is possible to obtain the voltage necessary for the stable starting of the discharge lamp.

Filed: 1996-09-25
Abstract: PROBLEM TO BE SOLVED: To perform centering of a gasket main body and/or solid-holding without greatly increasing costs by fitting a ring-like metallic flat plate for a socket and spigot part engaging in a groove in the inner peripheral side of a gasket main body. SOLUTION: In a spiral wound gasket 1 constructed by spirally winding a metallic hoop material 2 and a filler 3 by stacking these materials, a ring-like metallic flat plate 4 is provided in a groove 1b on the inner peripheral side of a gasket main body. Thus, since the ring-like metallic flat plate 4 for socket- and-spigot engaging exists in the inner peripheral surface of the gasket main body, the flat plate 4 is brought into contact with the outside of the counter lock part of an exhaust pipe and thus, centering is performed without shifting of the gasket main body toward the pipe inner side and, also since contact is prevented between the filler 3 and exhaust gas, a seal is maintained for a long time.  Further, since only ring-like flat plate 4 having, for example, a thickness of 1mm or lower, is provided in the inner peripheral part of the gasket main body, manufacturing costs are greatly reduced.
