Title: Discharge position detector in wire electric discharge machine
Inventor: OBARA HARUKI
IPC: B23H7/04
Filed: 1987-10-31
Abstract: PURPOSE:To detect a discharge position accurately as well as to make the presence of concentrated discharge easily discrimable by detecting each differential value of a current flowing in two energizers, and calculating the discharge position between a wire electrode and a workpiece by the difference. CONSTITUTION:When a discharge current (i) flows between a wire electrode 1 and a work 2 from a working power source 3, each differential value of discharge currents i1, i2 flowing in both upper and lower energizers 4, 5 is detected by coils 9, 10, and a signal S1 is outputted out of a divider 13 via a differential amplifier 11 and an adder 12, and it is held by a circuit 14 by output of a timer 15 triggered by the discharge current i2, thereby issuing output S2. Then, it is compared with reference voltage V1-Vn by comparators C1-Cn, and one shot multivibrators M1a, M1b... are triggered, thereby outputting output pulses S6-S1. However, when concentrated discharge is generated, a value of the output S2 is not varied, and since output of a one shot M is gone, an H signal 12 is outputted out of an OR gate 16, thereby controlling the working power source 3, hydraulic pressure, wire tension or the like, and thus the concentrated discharge is released.

Title: Drop on-demand ink jet recording head
Inventor: FURUKAWA TATSUYA
IPC: B41J2/045
Filed: 1987-10-30
Abstract: PURPOSE:To obtain a small-size and high-reliability ink jet recording head, by disposing an oscillating surface of a laminated oscillator opposed to a nozzle inlet open part and preventing the contact of a recording liquid with the oscillator. CONSTITUTION:A recording head is composed of a laminated oscillator 1, oscillator holder 2, nozzle plate 3, RTV rubber 4, nozzle 5, oscillating unit surface 6 opposed to the nozzle, and electrodes 7, 7'. The laminated oscillator 1 is disposed so that one end is sealed to the oscillator holder 2 and the opposite surface is opposed to the nozzle 5. Since the oscillating surface is directly opposed to the nozzle, a recording liquid is discharged out of the nozzle in a good efficiency. The use of a laminated type for the oscillator enables a small size head. Furthermore, the RTV rubber 4 is loaded to a gap between a deformation-free ceramic 1b of the laminated oscillator 1 on the nozzle side and the oscillator holder 2 to prevent the recording liquid from coming into contact with the laminated oscillator; this construction prevents the leak due to the recording liquid.
