Title: Pulse laser device
Inventor: AKITA TOMOHITO
IPC: G02B27/00
Filed: 1989-02-20
Abstract: PURPOSE:To extract only pulse laser light which has light intensity within a constant range selectively by providing a photodetector on one separation optical path of a beam splitter and a light delay means on the other, selecting only a detection signal which has a prescribed output level from the photodetector, and opening and closing an optical shutter. CONSTITUTION:Part of the pulse laser from a pulse laser generation part 2 is reflected by the beam splitter 6 and photodetected by a PIN photodiode 8. The PIN photodiode 8 outputs a detection pulse having a voltage level corresponding to the light intensity of the pulse laser and the detection pulse is inputted to a level selecting circuit 16 through an amplifier 14. The level selecting circuit 16 selects and outputs only a detection pulse whose level is between an upper and a lower threshold value. Then an optical shutter driving circuit 18 is actuated with the selected detection pulse to generate driving pulses for opening and closing the optical shutter 12. Consequently, only the pulse laser light which has light intensity within the constant range can be extracted selectively.

Filed: 1981-03-24
Abstract: PURPOSE:To facilitate the lead-out of a lead electrode, by setting the driving electrode to both faces of the center polarized region of a piezoelectric porcelain plate having nonpolarized both ends in the length direction of the porcelain. CONSTITUTION:A strip type driving electrode 2 is set to both faces of the central polarized part of a piezoelectric porcelain plate 1 having nonpolarized both ends in the length direction of the plate 1. Thus the width 2H1 of the electrode 2 is reduced. The width/length vibration propagating a thin piezoelectric porcelain plate having a finite width shows the high range cutoff type decentralizing properties, and the energy can be enclosed by setting a higher curoff frequency at a region where a frequency rising type electrode, i.e., a driving electrode than its peripheral area. Furthermore the cutoff frequency of the width/length vibration increases by decreasing the ratio between the width of the electrode 2 and the width of the plate 1. And this cutoff frequency can be increased more than that of the nonpolarized mode.

IPC: C02F11/04
Filed: 1984-03-05
Abstract: PURPOSE:To greatly reduce the total running cost of a coke oven by subjecting surplus activated sludges produced from gas liquid activated sludge treating equipments to a methane fermentation treatment, charging surplus methane sludges into the coke oven and burning the same. CONSTITUTION:Surplus activated sludges from the activated sludge treating equipments are dehydrated in a hydrater, and are fed to a methane fermenter 11. Organic matters in the sludge is decomposed, gasified and desulfurized in a scrubber 17. Then, the organic matters are mixed with a coke oven gas, and used as a fuel. Surplus methane sludges produced in the methane fermenter 11 are subjected to a dehydration treatment in a belt press 25. Since the surplus methane sludges contain a large amount of ash contents, a dehydrated cake of a water content 1/4 the case of the surplus methane sludge is obtained. The dehydrated cake is burnt in the coke oven. On the other hand, a filtrate (separated water) is introduced into activated sludge treating equipments. Thus, heat loss is reduced by the decrease in the water content carried in the coke oven, and the amount of the gas liquor produced is reduced. As a result, the consumption of steam caustic soda is reduced. Further, a fuel is obtained by the methane fermentation.

Abstract: PURPOSE:To realize an elimination of the normal induced voltage through a simple constitution, by using an amplifier and a coupling transformer to extract the induced voltage that is generated on a piece of transmission line and then applying the amplified output to the rest transmission line pairs after turning the output into an adverse phase. CONSTITUTION:An earthing is given to the terminal distant away from the amplifier of the pair 1A among the pairs 1A and 1B of several transmission line pairs 1; while the terminal close to the amplifier is connected to the input terminal of the amplifier 3. Thus the induced voltage generated at the transmission line 1A is amplified, and this output is applied to the primary side of the coupling transformer 5. Then the voltage of adverse phase is applied to each of the rest transmission lines from the secondary side of the transformer 5 in an amount which is large enough to offset the induced voltage of other transmission lines. Thus the normal induced voltage contained in plural transmission lines can be eliminated. In such a way, an eliminator for normally induced voltage is realized with a simple constitution.
