Title: Quick lighting ballast circuit and quick lighting device for metal halide lamp
Inventor: TAKAHASHI YASUNORI
IPC: H05B41/18
Filed: 1992-06-29
Abstract: PURPOSE:To prevent the reduction in illuminance caused by long time use by feeding back the secondary coil output of a transformer to a pulse current amplifying circuit to make the secondary coil output current value constant. CONSTITUTION:When an abnormal current control thyristor 3 and a thermal switch diode 4 which are different in properly used voltage range are used, two transformers 51, 52 for voltage and matching are provided, and the secondary side of the transformer 52 is connected to a metal halide lamp 6. Further, the secondary side output of the transformer 52 is fed back 7 to a pulse current amplifying circuit 2, and the output of the circuit 2 is increased and decreased to make the secondary side output current of the transformer 52 constant. Thus, when electrodes are worn by the long time use of the lamp 6, and the distance between electrodes is increased to reduce the current, the output voltage of the circuit 2 is raised, a voltage higher than the voltage in initial stage of use is added to the lamp 6 to make the current constant, and a constant illuminance can be kept.

Title: Laser oscillator
Inventor: KITSUKAWA TAKESHI
IPC: H01S3/00
Filed: 1984-09-17
Abstract: PURPOSE:To enable early detection of water leakage by a method wherein the increase in water amount due to water leakage of cooling water supply pipes and the like in a discharge gas container is detected by a dew-point sensor, thus driving an abnormal operation means. CONSTITUTION:Normally the dew point in a casing 10 is kept at -40--60 deg.C; however, when a very small amount of water leaks out of the joint of e.g. a high voltage electrode cooling water supply pipe 9, this water amount mixes in the laser gas, and the water amount of the laser gas increases more than a predetermined proper amount of water, resulting in a rapid decrease in the due point. At this time, the dew-point sensor 11 detects this phenomenon, and a control circuit 12 sets in action and releases abnormal alarm; thus, the abnormality due to water leakage can be early detected.

Filed: 1997-07-18
Abstract: PROBLEM TO BE SOLVED: To provide a semiconductor device which minimizes the possibility of breakdown caused by static electricity and has a function of determining the height of a control substrate. SOLUTION: Terminals 7 and 8 are projected from a major surface of an element 1 and are protected against a shock by frames 4 and 9 engaged each other at their side walls. The terminals 7 and 8 short-circuited by a melting material 10 such as a wire solder to protect the element 1 from its breakdown caused by static electricity. After a control substrate is placed on the frame 9, the frame 9 is pushed down and stopped when the control substrate reaches the frame 4 to thereby determine a height of the control substrate. As the frame 9 is lowered, the terminals 7 and 8 are passed through openings made in the frame 9 and control substrate, and extruded from the control substrate.  Heat for melting solder to connect the terminals 7 and 8 to a circuit of the control substrate transmits through the terminals 7 and 8 and melts the melting material 10, at which time the material 10 falls, thus open-circuiting a circuit between the terminals 7 and 8. Connection and open-circuiting are carried out simultaneously so that no time will be given for static electricity to provide different potentials to the terminals 7 and 8.
