Title: Lighting and feeding circuit for gas discharge lamp
Inventor: ADORIANUSU MAATEINUSU YOHANESU
IPC: H05B41/24
Filed: 1988-12-28
Abstract: PURPOSE: To realize constant power consumption of a lamp during operation by regulating a frequency and cycle of a semiconductor switching element in an energizing state to generate a voltage between both ends of capacitor. CONSTITUTION: After therminal ends 4 and 5 are connected to a power supply, a constant voltage between both ends of a capacitor 15 can be generated based on the selection of a frequency and duty cycle of a semiconductor switching element 12 in a deenergizing/energizing state. A starting circuit activates a DC/AC converter, and then high-frequency switching elements 21 and 24 alternately attain an energizing and deenergizing state. The power of a lamp 1 is derived from the capacitor 15 to stably maintain it by means of a sensor element 22. A measured voltage between both ends of the element 22 is compared with a reference voltage supplied from a circuit 28 through a control circuit 27, and, for example, if a voltage between both ends of the lamp is lowered, the switching frequency of the switching elements 21 and 24 is reduced. This stably maintains power consumption of the lamp.

Abstract: PURPOSE:To enable sheet resistance to be lowered enough and besides to enable Sb silica-spin-on without generating rosette by providing the vacuum drying process, the process of implanting O2 plasma, and the process of applying specific temperature for vitrification after application of Sb silica solution. CONSTITUTION:After the process of applying Sb containing silica solution to the main face of a semiconductor substrate 1, the vacuum drying process of the Sb containing silica application layer 3, the process of heating it to 200-500 deg.C, and the process of implanting O2 plasma are provided. Since the Sb glass 3 is Sb2O3 or Sb2O5, and rosette is in the form of Sb-O-Si, enough O2 is supplied to the Sb silica application layer 3. As a result, the Sb glass 3 changes from Sb2O3, which is strong in sublimation property, to Sb2O5, which is free of sublimation property, and the coupling becomes firm, so the activity becomes high and it becomes easy to diffuse, and furthermore it becomes hard to give O to the bonding Sb-Si-. Hereby, Sb silica-spin-on, that generation of rosette is small and low sheet is obtained, can be realized.
