Patent JP-S6352921-A (JP)
Title: Electric discharge processing device
Inventor: TONOGI YUSUKE
IPC: B23H9/00
Filed: 1986-08-25
Abstract: PURPOSE:To have safe electrodischarge processing of electroconductive ceramics etc., by sensing electrode contact with a processing surface having a great resistance using the sensed amperage in a feed motor, during electrode feed in the processing direction, and by preventing damage to the electrode or work to be processed. CONSTITUTION:If a work to be processed 2 is of electroconductive ceramic having uneven resistance locally and, at the same time, an electrode 1 contacts that part of ceramic where resistance is extraordinarily large, i.e. ceramic itself with no electroconductivity, non-discharging condition continues in the gap, and a CPU 5 gives a command to send the electrode 1 further in the processing progress direction. Here a motor current sensor 7 to sense amperage in the motor is furnished to monitor the current continuously with the CPU 5, and thereby the electrode 1 and work 2 are protected. That is, if current to the motor 3 increases, the CPU 5 gives a reverse feed command for the electrode 1 when the amperage exceeds a preset value. Thereby the motor 3 is inverted to feed the electrode 1 for a certain while in the opposite direction to the processing, so as to separate from the work 2. Thus the electrode 1 and work 2 are prevented from damage.

Filed: 1986-08-25
Abstract: PURPOSE:To record data in a neat arrangement along a reference line on a recording material, by generating synchronizing signals the number of which corresponds to a scanning distance, and starting recording after counting a specified number of pulses of the synchronizing signals from the generation of a position detection signal associated with the detection of the reference line of the recording paper. CONSTITUTION:At the time of recording information such as characters on a recording material, synchronizing signals the number of which corresponds to a scanning distance are generated by a signal-generating means (a). A position-detecting means 9b) for detecting a reference line (e.g., a rule) or a reference point on the recording material is provided, and a recording position controlling means (c) performs such a control that a recording means (d) starts recording the information after a specified number of pulses of the synchronizing signals from the signal-generating means (a) are counted from the generation of a position detection signal by the postion-detecting means (b). Namely, the recording synchronizing signals are set into an input waiting state waiting the predetermined number (alpha) of times, thereby preventing the possibility of recorded images overlapping with a rule of a table or the like due to execution of a recording operation immediately after detecting the rule. As a result, it is possible to record data in a neat arrangement along the role.
