摘要： PURPOSE:To make the troubleshooting of cause to failures easy, by storing an operation waveform at normal state, keeping this storage unchanged and detecting a failure through the change in the operation waveform. CONSTITUTION:In a failure detector 12, if a waveform comparator 24 detects a failure in a controller, a command signal to stop the collection of endless data is given to an endless data storage 27 after a prescribed time and the state of an analog signal 11 and a digital signal 10 of the controller before and after the generation of the failure is stored. This signal is trnasferred to an auxiliary storage device 27 such as a cassette tape for storage. When a display device shows the detection of the failure, the data stored in the device 27 is returned to the storage device 26, and the storage of the number of on/off times of a speed reduction relay can output the number of operations of the controller and at what number of times of the operation the production of the failure takes place to a printer 28. The information of the controller after and before the production of failure is outputted to a recorder 30 via an interface 29.

摘要： PURPOSE:To obtain an elevator system of high reliability by detecting the pulse to be generated next with one pulse out of three sets of the pulses generated from an AC speed generator as a reference thereby detecting the rotating direction of the AC generator. CONSTITUTION:Three pulses phi1-phi3 per cycle are generated synchronously with the interwire voltage of the output of a speed generator ACPG revolving synchronously with an electric motor driving a moving body for an elevator, etc. The outputs of Q1 of an FF1 and Q2 of an FF2 are made L level by the pulse phi1 which is used as a reference out of these pulses, and the outputs of the FF1, FF2 are inverted by the pulse generated after phi1, whereby the phase sequence of the pulses phi1- phi3 is judged MPU.

摘要： PURPOSE:To realize the cost reduction for the phase shift controller by providing the feedback winding to the magnetic phase shifter in order to secure the negative feedback for the input signal of the pulse transformer and thus securing the minor capacity for the DC power source needing stability as well as to secure the non- stability for the DC power source of the major capacity respectively. CONSTITUTION:Transistors Tr6 and Tr5 conduct in accordance with the positive and negative half cycles of power source AC. When control current ic is flowed to the control windings of magnetic phase shifters MA4 and MA3, these phase shifters are turned on to apply the voltage to the bases of Tr8 and 7 via the current given from constant voltage source RV. And the current flows to pulse transformers PT2 and PT1 from DC power source E2 via Tr8 and 7. Thus the gate pulse is induced at the secondary sides of PT2 and PT1 to be applied to the gates of main thyristors MT2 and MT1. Feedback windings NR3 and NR4 are provided to phase shifters MR3 and MR4 each to secure the opposite polarity to the AC winding, and thus the negative feedback is secured to the input signals of PT1 and PT2. Accordingly, the steady gate pulse can be obtained regardless of the fluctuation of the large- capacity power source E2 in the amplifying means.
