IPC: C03B27/004
Filed: 1989-12-19
Abstract: PURPOSE:To prevent the generation of crack of glass during cooling by lowering the clamping force before the tensile stress generated in a plate glass by cooling exceeds the strength of the glass in the quenching of a heated plate glass in a state clamped with a solid contacting material. CONSTITUTION:A bending and quenching apparatus is constructed of a male mold 7 and a female mold 8. A clamping apparatus 11 to constantly press the center of a side of a plate glass G to the female mold 8 is placed at a side of the female mold 8.

At the same time, the glass is tempered by quenching with solid contacting materials consisting of the male mold 7 and the female mold 8. The clamping force is temporarily lowered before the stress caused by the cooling exceeds the strength of the glass and the plate glass G is allowed to slide along the female mold 8 to cancel the generated stress. The clamping force is again increased and the cooling is continued to effect the quenching and reinforcement of the plate glass G.

Title: Discharge-lamp lighting device and lighting system
Inventor: KUDO HIROYUKI
IPC: H02M7/217
Filed: 1997-11-28
Abstract: PROBLEM TO BE SOLVED: To provide a discharge-lamp lighting device not generating heat in its life-ending stage. SOLUTION: Voltage is increased by actuating a field-effect transistor Q1. Voltage VDC of a capacitor C1 is controlled to be constant based on a full-wave rectifying circuit 1, the voltage VDC of the capacitor C1, and drain current. If the voltage VDC of the capacitor C1 exceeds a fixed value, for example, because of half-wave discharge in a fluorescent lamp FL, an input to a comparator 8 is fixed at a constant voltage by a Zener diode ZD1, irrespective of input from a multiplier 7. Drain current ID of the field-effect transistor Q1 is controlled to be constant. Heating is prevented by preventing input current IIN and the drain current ID of the field-effect transistor Q1 from increasing more than necessary.
