    摘要: A process and apparatus for controlling an electric discharge machine consisting of applying a pulse voltage across a working gap when the predetermined time of interruption of the electric discharge has lapsed and when the interpolar voltage has exceeded a reference voltage, increasing the reference voltage and lengthening the time of interruption of the electric discharge when the rate of abnormal discharge occurrence becomes greater than an allowable rate and decreasing the reference voltage and reducing the time of interruption of the electric discharge when the rate of abnormal electric discharge occurrence is less than an allowable rate.

    摘要: An optical reflection sensor emits light and its reflection from a target object is received. A signal processor carries out a measurement on the received reflected light such as the distance to the target object each time the reflected light is received. Repeatability of measured values is calculated and displayed on a display device incorporated into the housing of the sensor. The display device may have two display areas such that the calculated repeatability and the measured value can be displayed simultaneously. The calculated repeatability may be compared with a specified threshold value, with the result of the comparison displayed. The housing may also incorporate an input device through which a required level of accuracy may be set.

    摘要: A sensor system includes a plurality of sensor bodies arranged aligned and adjacent to each other, each of said sensor bodies being connected to an electric cord including at least a signal line via a connector. Each connector has a power feed terminal, and a detachable fitting for electrically connecting the power feed terminals of the connectors is provided between the connectors. The power supplied to the connector of any of the sensor body through the power feed line in the electric cord is distributed to the power feed terminal of another sensor body through a row of connectors. By this configuration, the number of power feed lines for the overall system can be significantly reduced, and common bodies not distinguished for the main and sub bodies can be used as the sensor bodies, whereby the cost can be reduced and inventory management can be facilitated. Further, when any of the sensor bodies fails, it is possible to simply exchange the failed sensor body only, while maintaining the use of the electric cord that has been used.

    摘要: An apparatus is provided with a component feeding member for feeding electronic components having lead wires in a tape-bonded state, an insertion head for separating the electronic components fed from the feeding member from the tapes and inserting to holes of a board, and a fixing head facing the insertion head via the board for cutting and folding the lead wires of the inserted electronic component in the board thereby fixing the electronic component to the board. AC servo motors operating independently of each other are individually set in the insertion head and the fixing head, which are controlled by a device so as to be synchronous with each other.
