摘要： In a cage position detector for a hydraulic elevator, there is provided a detector for measuring the time duration of the power failure, when the power fails. An amount of sinkage of a cage during the power failure is obtained by the time duration of the power failure and an average sinkage amount per unit time provide in advance. A cage position, which has been detected just before the power failure, is corrected by the above obtained amount of sinkage of the cage. A cage position, from which the elevator is to reopen a normal operation for service after the recovery of power, is specified by the corrected cage position. According to the present invention, even though the cage sinks during the long power failure, it is prevented to lose the true present position of the cage, from which the elevator is to reopen the normal operation after the recovery of power.

摘要： There is disclosed a cryopump for effecting a cooling operation by a freezing medium such as liquid helium. A plurality of radiation-heat shield plates (1) for protecting cryopanels (2) against an external heat radiation are provided in opposed relation to a gas inlet of the cryopump. Particularly, a plurality of groups of such radiation-heat shield plates (1) are provided in such a manner that the radiation-heat shield plates (1) of each group are arranged in a multi-stage manner in registry with one another in the direction of the depth of the cryopump and are disposed in parallel relation to one another. Each of the cryopanels is disposed adjacent to a rear surface of respective radiation-heat shield plates facing away from the gas inlet. With this construction, the gas molecules reflected by those radiation-heat shield plates and by a rear wall of the cryopump, are less liable to reach the gas inlet, and tend to be condensed at an increased rate on those cryopanels (2).

摘要： A communication means 40 for transmitting and receiving signals between an elevator controlling device 10 and an elevator monitoring device 20 based on a concept of serial multiplex transmission is provided near or within the elevator monitoring device 20. An input/output interface 44 having a buffer circuit 47A, which stores status signals transmitted to the communication means, is provided to transfer the output of this buffer circuit 47A via photocouplers 46 to a buffer circuit 27A of an input/output interface 27 of the monitoring device. In this way, the number of wires required for signal transmission or reception between these devices is reduced, and the signal voltage of these devices can be set freely by insulating signals transmitted to and received from the photocouplers. These results in turn impart greater freedom in the design of the elevator apparatus.

摘要： In an elevator apparatus, by use of a microcomputer (1), a signal is supplied to a base driving circuit (5) so as to turn driving control elements on/off to generate a pulse-width controlled voltage to thereby control the rotation of a door driving motor. An elevator stoppage signal and a door opening/closing allowing signal (8) are supplied from an elevator control means (9) to the microcomputer (1) and the base driving circuit (5). The base driving circuit (5) has a double system for its door opening operation so that it should not perform the driving of opening a door when the signal (8) shows the fact that the elevator is not in stoppage and the location is outside the zone in which the opening/closing of the door is to be allowed.
