Filed: 1983-08-02
Abstract: PURPOSE:To output a signal of a prescribed frequency with high stability by setting a time width produced from a pulse generator via a monostable multivibrator longer than a re-synchronism locking time of the phase locked loop attended with the switching operation. CONSTITUTION:When the output signal of oscillators OSC1, OSC2 is controlled switchingly, a control signal is fed to a pulse generator PG, from which a pulse of a pulse width of tau1 is generated. The pulse is fed to a monostable multivibrator MMV, from which a pulse having a prescribed time width 72 is outputted. The said pulse is fed to an AND circuit AND and a comparison output voltage of a phase comparator PD is fed to a voltage discriminator VD, where whether or not the pulse exceeds the upper and lower limit values is discriminated and the output is fed to the circuit AND. Since the time width tau2 is set longer than the resynchronism locking time of a phase locked loop PLL attended with the switching operation of a switching device SW, the transient increase value of the phase comparator output voltage attended with the switching operation of the switching device SW is suppressed.

Title: Mechanical-biological sewage treating plant for purifying sewage and sewage purifying method
Inventor: EERITSUHI TSUIMUMERU
IPC: C02F3/08
Filed: 1984-07-09
Abstract: In a plant for the mechanical-biological treatment of sewage, an immersion element is rotatably mounted within a settling tank so that the element rotates about a horizontal axis. The immersion element includes a perforated outer tube and an inner tube spaced concentrically within the outer tube. The opposite ends of the tubes are connected by plates so that the immersion element forms an enclosed space filled with support elements for biological growth. The outer tube is formed of sheet metal and holes, elongated in the rotational direction, are punched out of the sheet metal with the punched material forming outwardly directed projections. The immersion element is rotated by a drive motor and during rotation at relatively high speeds the projections from the outer tube extend above the water level and draw air into the sewage and form a sewage-air mixture rotating at high speed.

Filed: 1983-08-01
Abstract: PURPOSE:To prevent the unbalancing of the distortion factor between output signals from being caused by applying an output of a parallel negative feedback amplifier to the 1st and 2nd negative feedback power amplifiers so as to give an output of both power amplifiers to a load. CONSTITUTION:An input signal fed from a signal source SG is outputted to its output terminal 2 via the parallel negative feedback amplifier A and fed to an input terminal of the negative power amplifiers AMP1, AMP2. Further, each output signal of the AMP1, AMP2 is outputted as a synthesis signal among a fundamental signal from a signal source SG, a distortion component generated by the parallel feedback amplifier A and a distortion component generated from the AMP1, AMP2. Since the distortion generated in the AMP1, AMP2 is nearly equal, no unbalance of the distortion factor is produced between the output signals of the AMP1, AMP2. Further, the input impedance of the amplifier A is sufficiently large and the decrease in the input impedance viewed from the input terminal is not produced.

IPC: G01N3/32
Filed: 1984-07-06
Abstract: PURPOSE:To estimate the residual life of the strength of a structural material to stress in a non-destructive manner, by estimating the change in coefficient of X-ray absorption with the elapse of time. CONSTITUTION:The relation of the deterioration in strength sigma to a time (t) and that of a hard X-ray absorption coefficient change ratio DELTAmu to the time (t) are calculated at least at four points or more in a non-destructive manner by actual measurement. Next, the relation of the strength lowering ratio DELTAsigma to the hard X-ray absorption coefficient change ratio DELTAmu is calculated as DELTAsigma=aDELTAmu<b> [(a) and (b) are constants]. Because residual strength sigma is a value calculated by subtracting the strength lowering ratio DELTAmu from initial strength sigma0, a material reaches its life at the point of time when residual strength sigma reaches the max. stress sigmad applied to the material or less.

Abstract: PROBLEM TO BE SOLVED: To make noises simply and accurately discriminable by providing a constitution, that operates and obtains modulation coefficient including diameter, flow speed and sound speed with a microprocess or, and discriminates the noises by using the coefficient. SOLUTION: The ultrasonic wave, which is sent into fluid to be measured from an ultrasonic transmitter 23, undergoes phase modulation with Karman vortex. The wave is made to be the pulse through each circuit. The phase detection is performed with a reference-wave signal SR as the base.

In the microcomputer 36, a frequency fVD in correspondence with the amplitude of the vertex signal and a reference clock CL1 are inputted furthermore. The processor CPU of the microcomputer 36 uses these inputs, obtains the flow speed of the fluid and the sound speed in the fluid, computes the modulation coefficient and judges whether the modulation coefficient is located between an allowable noise lower limit value and an upper limit value stored in a memory MEM or not.  When the coefficient is located between the values, the output is allowed, and if not, the output is cut.
