摘要： PURPOSE:To automate the measurement of an amount of subsidence of a stand of a large-scale machine, such as a turbine, and continuously and arbitrarily measure and monitor an amount of subsidence of such a stand, by providing detectors at bench marks on the stand, and operate levels of the marks on the basis of signals from the detectors. CONSTITUTION:Bench mark boxes 18a-18n are provided at bench marks on a horizontal surface of a turbine stand 1. Automatic level detectors 80 are set in the boxes 18, and outputs from the detectors 80 are applied to detecting circuits 81. Outputs from the circuits 81 are sent to a central turbine control unit 82 to be collected in a recorder 87. Signals collected in the recorder 87 are arbitrarily selected by a switch 89 and input into a microcomputer 95 so as to be subjected to operation. A relative variation amount on a horizontal surface 3 of the stand 1 and an absolute level with respect to a reference point are displayed on a pen recorder 90 and an oscilloscope 91.

摘要： PURPOSE:To provide a low-cost, integral structure for electromagnetic shielding by using conductive elastic shield plates having a shape suitable for elastic retention in place of the conventional conductive elastic material used to fill the gaps between shield plates in the prior art. CONSTITUTION:An electromagnetic shield plate is made mainly of conductive elastic material and is provided with a curved elastic side member 2a to maintain contact with an adjacent package shield plate 3. Therefore, there is no need for the shield material that fills the gap between electromagnetic shield plates. The shield plate 2 includes upper and lower end extensions that protrude toward the front of a mounting frame, and they have projections to be engaged with upper and lower U-grooves in the mounting frame. The shield plate can be fixed to the mounting frame by pressing the conductive elastic material and can be removed only by pressing the extensions inward.

摘要： PURPOSE:To high efficiently perform electro-chemical electric discharge machining, by duplicating an electric discharge machining pulse-state power source to an electro-chemical machining power source. CONSTITUTION:An electro-chemical machining power source 12 and electric discharge machining power source 13 are applied between an electrode 1 and work 2 to simultaneously perform both electro-chemical machining and electric discharge machining while flowing electrolytic machining fluid 3. The electro- chemical machining power source 12 generates a flat output waveform, while the electric discharge machining power source 13 generates an output waveform having pulse width from about 0.1mus to several ms. As a result from these duplication, actually applied output between the electrode 1 and the work 2 is a constant voltage electro-chemical machining power source as viewed from electro- chemical machining, and a large current increases a machining amount as compared with a single-phase full-wave power source, while high voltage is applied as viewed from electric discharge machining, and an electric discharge is easily caused, further an arc discharge is cut off because of a pulse-state discharge waveform, thus a continuous arc discharge phenomenon can be avoided.

摘要： PURPOSE:To prevent short circuit with the article to be worked during working process and improve the working efficiency by installing a noninducting guide means in the top edge outer diameter part, in the hollow pipe electrode for working a deep hole by means of the electrochemical effect such as electric discharge, electrolysis etc. CONSTITUTION:The pads 2 as guide means are installed in the top edge outer diameter part of a hollow pipe electrode 1. The pads 2 are arranged, for example at four places at equal intervals on the circumference, and each pad 2 forms an arcuate form, and the thickness t is set nearly equal to the electrolytic gap for discharging the electrolytic liquid and worked sludge from a worked article. As the pads 2 are interposed between the inner diameter of a hole and the top edge outer diameter part of the hollow pipe electrode 1 during boring work, the pads 2 guide the electrode 1 along the inner diameter of the hole, and vibration at the top edge can be suppressed, and at the same time, the top edge part contacts with the inner wall of the hole of the worked article, and generation of short circuit failure is prevented.

摘要： PURPOSE:To simplify the control of feed speed and positions necessary to convert the feed speed on a machine and expedite machining of a work by comparing position detecting signals of a machining apparatus with positional signals stored in a computer. CONSTITUTION:An ITV camera is set over a work, the plane figure of the work is displayed by giving picture signals from the ITV camera to a monitor TV 32 and at the same time positional data are input to a computer 30 and memoried there. Control signals to an X axis servo unit 18 and a Y axis servo unit 19 are made by both signals obtained when signals from read heads 6, 9 are counted by counters 36, 39 and set points which have been memorized already.

摘要： PURPOSE:To prevent a numerical control processing device from operating erroneously by comparing a command signal with a displacement signal memorized by a memory device. CONSTITUTION:By conducting a simulative cutting operation in accordance with a command information from a tape reader 24, an entry command signal 80, an address signal 79 and an output pulse from a position detector 33X are entered in a memory device 57. On the occasion of conducting an actual cutting operation, the entry command signal 80 is set to OFF and a read command signal 81 is set to ON, and the output pulses entered at the time of the simulative processing operation are read out in order with progress of the actual cutting operation. A signal 76 from the memory device 57 is compared with an output from a pulse distributor 27 by a comparator 74. An output difference signal is zero as long as these two signals are according with each other, but if they do not accord with each other, a difference signal 77 is put out from the comparator 74, and a stop command signal is given from a stop command signal preparation circuit 63 to a positioning control section 26 so that an entire operation is temporarily stopped.
摘要翻译：目的：通过将命令信号与由存储器件存储的位移信号进行比较来防止数字控制处理装置错误地操作。构成：通过根据来自带读取器24的命令信息进行模拟切割操作，将来自命令信号80，地址信号79和来自位置检测器33X的输出脉冲输入到存储装置57.在这种情况下进行实际的切断动作时，进入指令信号80被设定为OFF，读取指令信号81被设定为ON，并且在模拟处理操作时输入的输出脉冲按照实际切换操作的进行顺序被读出切割操作。来自存储器件57的信号76与比较器74的脉冲分配器27的输出进行比较。只要这两个信号彼此相符，输出差分信号为零，但是如果它们不相符从比较器74输出差分信号77，从停止指令信号准备电路63向定位控制部26提供停止指令信号，使得整个操作暂时停止。
