IPC: G02F1/01
Filed: 1982-03-24
Abstract: PURPOSE:To raise the efficiency of stabilized light, by executing the stabilizing control by nondiffracted light which is not diffracted by an optical modulator, in laser output light. CONSTITUTION:Primary or higher diffracted light I1 is obstructed by a light shielding plate 12, and only ''O''-degree light I is utilized. For instance, when fluctuation is generated in a state of a laser ocillator 1, and its output light IL drops to IL2 from IL1, the intensity of ''0''-degree light I0 is reduced, and an output level S of an amplifier 5 drops to a value SB which is lower than a stationary state level SA. As a result, it is added to output voltage Vd1 in case of stationary state by an adder 7, becomes new output voltage Vd2, and an operating point of an optical modulator 2 is shifted to a point C. ''0''-degree light of the point C is added to the level Vd2 by the adder 7, is brought closer to a point D corresponding to a reference value R, and the system is stablilized at last. In this way, the efficiency of stabilized light can be raised.

Filed: 1996-02-08
Abstract: PROBLEM TO BE SOLVED: To provide a simple pollution load mass recorder used for sewage, a pollutant discharge prevention system necessary to build up a fair rate system using the recorder, and an economical closed system. SOLUTION: This pollution load mass recorder for sewage moves a highly water absorptive and biodegradable filter 8 of the preset length, depending on a polluted drain volume from a tank and in this state, causes a pollutant contained in discharged sewage to come in contact with and adhere to the filter 8 for the automatic recording of the pollutant. Then, the weight or the volume of the pollutant is measured, thereby calculating the mass of a pollution load. In a system having the structure where the aforementioned recorder is adopted and drain temporarily contained in the tank is discharged to a sewer 14, sewage service rates are determined on the basis of the automatically recorded mass of the pollutant contained in the drain, thereby enabling a pollutant discharge prevention system to be established for a reasonable and fairer service rates system. Furthermore, when the recorder is used for a simplified closed system of transpiration type, the occurrence of clogging can be prevented, and the closed system can be formed to prevent a pollutant discharge and operate over a semipermanent period.
