Title: Ion laser tube
Inventor: YAMAGUCHI NORIYUKI
IPC: H01J63/08
Filed: 1992-03-30
Abstract: PURPOSE:To eliminate the need of any expensive oxide-impregnated cathode from an ion laser tube by constituting the cathode of the tube of a pair of closely arranged electrodes insulated from each other. CONSTITUTION:Electrodes 11 and 15 are arranged in a state where they are insulated from each other at a fixed interval. The front end sections of the electrodes 11 and 15 are bent so that the end sections can face each other. A voltage for main discharge is applied across the electrode 11 or 15 and an anode 13 and main discharge is generated by the discharge between the electrodes 11 and 15. When the main discharge starts, secondary electrons are discharged from the electrode 11 or 15 due to ion collisions and the electrode 11 or 15 starts to exert the function of a cathode and the main discharge is maintained. Therefore, an inexpensive ion laser tube can be obtained, because the structure of the tube becomes simple and the tube does not require any expensive oxide-impregnated cathode.

IPC: G01N21/00
Filed: 1993-03-30
Abstract: PURPOSE:To accurately measure the concentration of a sample even when the concentration is high. CONSTITUTION:The concentration and light absorption factor of a sample are found by irradiating the sample with a laser beam from an incoming port 2a (or optical fiber) after setting the sample in a casing 1 through a sample inlet 1a and generating pressure waves from the irradiated part of the sample by thermal expansion and, on the other hand, detecting the pressure waves propagated towards the periphery of the sample in the casing 1 with a pressure sensor 3 and fetching the detected signals by the sensor 3. When the concentration of the sample to be measured becomes higher, the incoming port 2a and an outgoing port 2b (or optical fibers) are brought nearer to the center of the sensor 3 to adjust the pressure received by the sensor 3 so that the pressure cannot drop even when the concentration becomes higher. Namely, the concentration of the sample is highly accurately measured even when the concentration is high by reducing the distance from the port 2a (or optical fiber) to the center of the sensor 3 so that the laser light can be sent to the front face of the sensor 3 at the time of irradiating the sample with the laser beam.

Abstract: PURPOSE:To maintain adequately and automatically the angle of a torch during welding without measuring preliminarily a groove angle in the stage of welding a fillet butt joint by oscillating uniformly the arc to the right and left of the joint line and controlling the angle of the torch in accordance with the voltage waveform of the right and left arcs. CONSTITUTION:A welding torch 3 is provided on a reference line at a torch angle phi and an arc C is generated in a welded joint A of an angle alpha consisting of members 1, 2 and is oscillated at a specified angle theta from the reference line in the case of welding said joint A (groove slope with a butt joint). Then the arc lengths R, L differ from C and therefore the arc voltage during oscillating changes as well. The voltage waveform of the arc is as shown in the figure (t is time) when the arc is oscillated linearly to, for example, the right and left at a specified speed. If the arc voltages when the arc is at the reference line and R, L are designated as Vac, Var, Val, phi=1/2alpha, Var=Val and the voltage difference between both is zero. The torch angle is thus controlled to turn the torch around the arc point in such a way that the difference in the voltage waveform at every half period T/2 of the right and left is made to zero.
