摘要： PURPOSE:To enable remote diagnosis of abnormality of equipment with a simple structure by collecting a normal sound of a sound source for diagnosis in a rotary machine or the like to be memorized into a data recorder as necessary comparison signal for the diagnosis. CONSTITUTION:When an operator 100 operates a console 13 before the start of a diagnosis, a normal acoustic signal from a sound source 50 as collected with a microphone 1 is recorded into a data recorder 3 as diagnostic comparison signal based on a control signal 8 of a controller 12. Then, when the sound source 50 is diagnosed, an acoustic signal form the sound source 50 is applied to a speaker 5 through a gate 6 and at the same time, a reproduced signal from the record 3 is applied to a speaker 4. Therefore, the operator can catch the two acoustic signals as audio information simultaneosuly thereby enabling the extraction of abnormal sounds of the sound source at a remote point.

摘要： PURPOSE:To receive a signal with good quality by extracting a horizontal synchronizing signal or a vertical synchronizing signal included in a composite video signal as a standard signal for supervising a reception level and supervising a minimum level in response to a reception sensitivity so as to prevent that a command signal does not reach a mobile body and the mobile body cannot return any more. CONSTITUTION:The composite video signal 300 is extracted from a monitor 7 and transmitted to a synchronizing separator circuit 31. A horizontal synchronizing signal 301 separated by the synchronizing separator circuit 31 is converted into an n-bit digital quantity by an A/D converter 33 and fed to a comparator 34, and when the result is smaller than the level set by a digital switch 35 in advance, an alarm signal 304 is outputted to an error processing section 36.

摘要： PURPOSE:To quickly and accurately detect the cavitation of an electromagnetic pump used for fast bleeder reactors, etc. CONSTITUTION:By providing an electrode 10 so that the electrode 10 can be brought into contact with a working fluid 5 through the duct 8 of an electromagnetic pump and connecting a high-frequency signal source 11 to the electrode 10 so that most of a high-frequency current can be made to flow near the interface between the fluid 5 and duct 8, the generation and collapse of a cavitation are detected from changes in electrical admittance. Since the electromagnetic pump can be operated within the extent within which no cavitation is generated by accurately and quickly detecting a generated and collapsing cavitation, the damage to the duct by cavitations can be prevented and the service life of the material used for the duct can be prolonged.

摘要： PURPOSE:To improve pump efficiency by using a flat pump duct to an electromagnetic pump, around which an inlet of conductive fluid is provided and in the center of the flat surface of which an outlet is provided, etc. CONSTITUTION:A pump duct 1 of an electromagnetic pump is shaped flat, provided respectively are an inlet piping 4 surrounding its flat surface into which conductive fluid flows and an outlet piping 5 in the center of its flat surface from which the conductive fluid flows. Stator yokes 2 are arranged around the outlet piping 5 facing the flat surface of the pump duct 1. Stator coils 3 are wound around the yokes 2 and excited by an excitation circuit with an AC current source 9, etc. Exciting current thereby flows to the stator coils 3 and alternating field is generated across stator yokes 2. With this alternating field the induction eddy current I flows to the conductive fluid and in compliance with Lenz's law electromagnetic force will work. With this electromagnetic force the fluid points to the outlet piping 5 in compliance with Fleming's left hand rule and is forcibly pushed out.

摘要： PURPOSE:To improve the radiation resistance performance by compensating a decrease in the current amplification due to radiation absorption to the prescribed degree by the regulation of the junction temperature of a semiconductor device. CONSTITUTION:A decrease in a current amplification foctor occurred by the fact that radiation dosage is absorbed to a semiconductor integrated circuit is detected by a detector, and expressed as vC/vB of the voltage drops of external resistors 23, 24, i.e., a signal voltage 30. If the voltage 30 decreases to a threshold voltage 31 or lower, a gate 29 is opened by an output signal of a comparator 28, and a supply current of a power source 36 is supplied to a Peltier element 10. The element 10 supplies thermal energy to a bipolar transistor for the integrated circuit, and the current amplification factor decreased due to the increase in the junction temperature Tj is increased and recovered. When it is recovered to the original value of the current amplification factor, thermal energy supply due to the element 10 is stopped, and the rise of the temperature Tj is stopped. The junction temperature Tj of the transistor can be controlled from this repeated regulation, thereby compensating the decrease in the current amplification factor due to the radiation absorption.
