Abstract: PURPOSE: To detect the malfunction of excessively high response to ultrasonic waves, to prevent erroneous judgement of correct measured values and to prevent generation of mistrigger by providing a malfunction detecting circuit.  
     CONSTITUTION: A time difference between the time for a counter 5 to count the output of an oscillator 1 and the propagation time t of the ultrasonic waves is detected at 7, and the oscillator 1 is so controlled as to reduce the time difference to zero. The propagation time is detected at 10 from the oscillatory frequency. In this instance, there are provided circuits 14 to 16, which are operative to generate output signals M of a preset pulse width after a preset time in response to the counting operation terminating signals W of the counter 5, and a malfunction monitoring circuit 13 having an FF 17 for comparing the signals M and the output signals Z of an ultrasonic wave receiving circuit 4. In case the generating time of signals Z is within the generating time of signals M, the output signals F are fed to a warning device.

Abstract: PURPOSE:To obtain a high neutron detection accuracy securing a stable property even in the use of a high-level neutron flux field by applying a conductive cover on the surface of an anode body to make an anode. CONSTITUTION:An anode 106 housed inside a cathode 102 is supported between insulation plates 104A and 104B at both ends thereof.

Title: A/d converter circuit
Inventor: TAKAYAMA SHIGERU
IPC: H03M1/38
Filed: 1991-02-27
Abstract: PURPOSE:To attain the A/D conversion with high accuracy without losing the operating speed by allowing a conversion cycle period control means to set a conversion cycle period of a most significant bit longer than a conversion cycle period of other bits. CONSTITUTION:Counters 28, 29 and decoders 10, 30 or the like are provided as conversion cycle period control means. Then the conversion cycle period control means sets the conversion cycle period of the most significant bit longer than the conversion cycle period of the other bits. Thus, even when a capacitance of the capacitor provided to the input of, e.g. the comparator circuit is set larger, when the conversion cycle period is longer in comparison with a time constant of the conversion circuit, an error at the A/D conversion is reduced, Moreover, since the conversion cycle period is set longer for the conversion cycle period of the most significant bit in which an error takes place at most and the conversion cycle period of the other bits is smaller than that, the reduction in the conversion speed is suppressed.

Title: Crest detecting circuit for radiation detector
Inventor: FUSHIMI KAZUO
IPC: G01T1/36
Filed: 1989-03-10
Abstract: PURPOSE:To improve the differential nonlinearity and to remarkably improve the counting rate by subjecting the output signal of a radiation detector to A/D conversion with a preliminarily determined clock period and successively integrating the output signal. CONSTITUTION:The detection signal obtained from a radiation detector 1 is sent to a parallel A/D converter 3 through a waveform shaping circuit which shapes it to an approximate square wave. The A/D converter 3 subjects the input signal to A/D conversion based on the clock signal supplied from a clock oscillator 4, and an obtained digital signal is sent to an accumulator 5 and a integrating circuit 7, which consists of a counter 6 which counts the overflow signal of the accumulator 5, and is integrated. A timing signal 9 generates a timing signal, which instructs the integrating circuit 7 to start and terminate the operation, on the basis of the output signal of the radiation detector 1. Integration is stopped when a prescribed number of A/D conversion values are integrated by the circuit 7, and the integrated value at this time is read out from a register 8 as the crest value. Thus, the counting rate is improved remarkably.

IPC: B01D71/70
Filed: 1983-04-05
Abstract: PURPOSE:To obtain the separation membrane having a high separation performance along with a high permeation velocity by film-forming a soln. of a polymeric material which is filtered with a microfilter having <=6mu maximum bore. CONSTITUTION:The gas separation membrane is manufactured by film-forming a soln. of a polymeric material which is filtered by a microfilter having <=6mu maximum bore and consists especially of a mixture of polyorganosilane and organopolysiloxane. In manufacturing the gas separation membrane, since the floating dust or a foreign matter such as insoluble polymer in the soln. is removed by the above-mentioned microfilter, the generation of defective parts is prevented in the dense layer of an asymmetric membrane which consists of a single layer consisting solely of the dense layer showing a selective gas separation property, or which consists of two layers of the dense layer and a porous layer showing no selective separation property and united to the dense layer. Thus the dense layer having extremely thin thickness can easily be formed.
