Title: Measuring instrument for dose of radiation
Inventor: BABA MATSUKI
IPC: G01T1/02
Filed: 1986-03-12
Abstract: PURPOSE:To enable energy evaluation with an individual dosimeter by using a sensor which outputs a pulse crest distribution corresponding to the energy of incident radiation and providing a means which calculates the ratio of the number of output pulses from plural pulse crest discriminates. CONSTITUTION:The pulse output of the sensor 1 is amplified by an amplifier 2 and plural pulse crest discriminators 3 discriminate pulse crests. Then, their crest discrimination outputs are sent to a trailing stage for dosage display and a divider 5 calculates and outputs the ratio of a high level output n1 and a low level output n2. Thus, the energy evaluation by the individual dosimeter becomes possible and the accuracy of safety control is improved.

Filed: 1981-04-09
Abstract: PURPOSE:To prevent the generation of short circuiting during changing over and to perform smooth crater treatment by reducing arc current at the end of welding and reducing the arc voltage after prescribed time then changing over the welding to the crater treatment. CONSTITUTION:In the TIG welding executed by controlling the distance between a W electrode and the work constant in such a way that arc voltage assumes a set voltage value, in the stage of changing over welding to a crater treatment upon ending of the welding, only the arc current is first reduced to the prescribed current in the crater treatment, and is controlled to the direction of making the arc length long, after which the arc voltage is reduced to the prescribed value in the crater treatment at the point of the time when the prescribed times elapses, whereby the crater treatment is accomplished. In a control circuit, the welding is started when a switch PB1 is turned on. Upon ending of the welding, a switch PB2 is turned on to turn relays CR6, CR7, timers TM6, TM7 and a relay CRTM successively on, whereby the crater treatment is controlled.

Title: Control system for pulse-width modulation type inverter
Inventor: KATSURAYAMA NORIYUKI
IPC: H02M7/06
Filed: 1986-03-12
Abstract: PURPOSE:To smoothly start a pulse-width modulation type inverter without a smoothing condenser discharging circuit by interrupting the supply of power to the condenser before a frequency signal becomes zero at stopping time in the step of stopping by reducing an output frequency. CONSTITUTION:When a deceleration/stop command is applied, a voltage/ frequency controller 11 reduces a voltage signal and a frequency signal at a predetermined ratio in response to a predetermined deceleration gradient. A switching period in an inverter main circuit 7 is gradually lengthened on the basis of it, and a voltage applied to a smoothing condenser 6 and hence the output voltage of an inverter is gradually reduced. A voltage signal from the controller 11 is set to zero at a time immediately before stopping to maintain a switching element 4 in an open state, thereby interrupting the supply of power to the condenser 6. A frequency signal is gradually reduced toward zero, and continuously output, and the main circuit 7 continues operating for a predetermined delay time and then stops.

IPC: G01R31/02
Filed: 1978-05-10
Abstract: PURPOSE: To insulate electrically a line and a detector circuit to make it possible to detect the induced current including DC by using a Hall element as the detector circuit in the in-phase current detector circuit which detects the induction trouble of the metallic transmission line.  
     CONSTITUTION: When induction indicated by the dotted line is received by cable 3, the induced current is flowed to the earth through in-phase current suppression coil 8' and equivalent longitudinal circuit impedance 11 which is connected to the neutral point of in-phase current suppression coil 8'. At this time, a part of the magnetic flux generated by windings 9' and 10' of coil 8' becomes a leakage magnetic flux and is coupled with Hall IC circuit 12. Consequently, a voltage corresponding to the induced current is generated across output terminals 13 and 14 of circuit 12. This voltage is amplified by amplifier 15 and is indicated by output meter 17. As a result, the detection in a wide measurement range from DC to a high frequency is possible because the Hall element is used for the detection of the induced current.
