Title: Highly repetitive pulsed laser electrode
Inventor: KANEKO EIJI
IPC: H01S3/038
Filed: 1987-03-18
Abstract: PURPOSE:To stabilize pre-ionization and laser oscillation characteristics by forming a plurality of grooves orthogonal in the direction of discharge to the creeping surface of an insulator between counter electrodes for a pre-ionizing electrode. CONSTITUTION:Groove sections 6C orthogonal in the direction of discharge are shaped at two positions in the direction of discharge of an insulator 6. Since the breakdown voltage of space is acquired in the groove sections 6C at two positions while creeping surfaces except the groove sections 6C are exposed to the discharge of the groove sections 6C on pre-ionization, voltage is hardly obtained. Consequently, the breakdown voltage of the groove sections 6C is determined by the discharge distances of the groove sections 6C, and is not fluctuated by discharge. Accordingly, pre-ionization is conducted by stable breakdown voltage at all times regardless of the number of repetition and repeating frequency of discharge, thus acquiring stable laser oscillation characteristics.

Filed: 1996-03-19
Abstract: PROBLEM TO BE SOLVED: To perform a method of inserting a light source and a sensor chip unit into a small hole or narrow plate by separating them from a photodetector. SOLUTION: A sensor chip 2 has a gold or silver thin film having a thickness of about 50nm to cause a surface plasmon resonance on the surface of a glass plate having the same refractive index a that of a prism 13 and connected to the upper bottom of a prism 13 via matching oil having the same refractive index as that of the prims 13. Or, the metal thin film may be deposited directly on the upper bottom of the prism 13. An incident side GI type optical fiber 5 and a reflecting side GI type optical fiber 6 are mounted at the lower bottom of the prism 13. Since the fibers 5, 6 are mounted in parallel in the same direction as that of the lower bottom of the prism 13, the chip unit has substantially the same size as that of the prism 13, and can be inserted freely if it is the hole of the size for passing the prism 13.  The fiber 5 introduces the incident light from a light source, and fiber 6 introduces the reflected light from the prism 13 to a photoreceiving sensor.

CONSTITUTION:Because a treated liquid is cooled by a cooling part 35 of a treating system piping 29, the temp. of the treated liquid is lower than that of an untreated liquid, that is, the specific gravity of the treated liquid is higher than that of the untreated liquid. As a result, an untreated liquid layer 19 and a treated liquid layer 23 are formed in the upper part of a liquid tank body 11 and in the lower part respectively, and a separation layer 21 is formed between them. Further, because an untreated liquid turning flow 43 is generated in the untreated liquid layer 19 and a treated liquid turning flow 45 is generated in the treated liquid layer 23 in the same direction as that of the untreated liquid turning flow 43, the untreated liquid turning flow 43 does not collide with the treated liquid layer turning flow 45, and the untreated liquid and the treated liquid are surely separated in the tank.
