Patent JP-H042944-A (JP)
Title: Electro-hydraulic servo type material testing apparatus
Inventor: UNO HIROSHI
IPC: G01N3/10
Filed: 1990-04-20
Abstract: PURPOSE:To prevent run away of an actuator at the time of power failure by inserting an electromagnetic valve between a pair of ports, which is closed with power supplied and opened with power cut. CONSTITUTION:When AC power is supplied to a hydraulic unit 7 and a DC power source 12 for a control circuit, an electromagnetic valve 15 is closed with power supplied. By controlling a servovalve 6 by a deviation signal SE consisting of a target load signal SM and a load detection signal SK subsequently, supply tubes 8a, 8b are connected to ports P1, P2, respectively so as to supply hydraulic pressure from the tube 8a to one of the hydraulic ports as well as to return the hydraulic pressure exhausted from the other hydraulic ports to the tube 8b. When power to the valve 15 is cut, the valve 15 is opened to short- circuit between the ports P1, P2, wherein even if hydraulic pressure is supplied to either hydraulic port, the hydraulic pressure is not supplied into a cylinder 1b but returned via valves 15, 6 to the tube 8b. As a result, even if the valve is unstable with a feedback loop not operated due to power failure, an actuator will not run away.

Title: Liquid jet head
Inventor: HASEGAWA KAZUMASA
IPC: B41J2/045
Filed: 1989-04-24
Abstract: PURPOSE:To readily accomplish liquid jet heads which can make the distribution of nozzles densified and the device is turned into multi-nozzled system as well as to produce at a high yield by generating a pressure wave in a pressure chamber in response to the displacing action of a piezoelectric film on the side wall of the pressure chamber. CONSTITUTION:A voltage is applied between upper electrodes 117 and 118 and a lower electrode 121, and side walls on both sides of a pressure chamber 111 turn into a piezoelectric element and come to be displaced inward. Then, liquid in the interior of the pressure chamber 111 produces a pressure wave, which transmits liquid in a liquid traveling channel 108 and in a nozzle 105 and is jetted out of a liquid jet orifice 114. At this time, liquid in a pressure chamber 112 adjacent to the chamber 111 produces a pressure wave. However, the liquid is not jetted out of an adjacent liquid jet orifice 115 if conditions such as the size of the pressure chamber and the length of the liquid traveling channel are set appropriately. Consequently, the liquid jet heads wherein nozzles are densely distributed and the device is turned into multi-nozzled system can be obtained. In addition, since the displacement between the piezoelectric element and the pressure chambers can be minimized, the high-yield liquid jet head is realized.
