Title: Production of ink jet head
Inventor: FURUTA TATSUO
IPC: B41J2/135
Filed: 1992-05-25
Abstract: PURPOSE:To simply produce a nozzle formed member to which nozzles are arranged in high density by applying through-hole processing to each of nozzle orifices by laser beam and applying blind-hole processing to the periphery of each of through-holes. CONSTITUTION:A through-hole is formed by processing performing the pulse irradiation with laser beam in alignment with the center line of a nozzle opening part to form the nozzle opening part 100. A nozzle orifice is formed at one place by this processing and a nozzle formed member 110 is produced by processing nozzle orifices at two or more places. When the short diameter direction of the nozzle orifices is allowed to coincide with a pitch direction, the nozzle orifices can be arranged in the highest density. Since the ink jet head using the obtained nozzle formed member has large nozzle volume, the menicus of an ink liquid after the emission of ink becomes stable and no air is drawn in. Therefore, flight characteristics stabler than conventional ones can be obtained.

IPC: G01R31/02
Filed: 1978-10-27
Abstract: PURPOSE: To continually monitor the deterioration conditions of a non-linear resistor, by detecting a resistance portion of the leakage currents of an arrester at all times.  
     CONSTITUTION: An electrode 10 is mounted in a shape that is opposed to a high- tension portion conductor 9 of an arrester, and arrester terminal voltage is detected by using impedance connected between the electrode and an earth.
