Title: Operating device for actuator
Inventor: FUJIMOTO YOSHIAKI
IPC: B66D1/44
Filed: 1988-11-17
Abstract: PURPOSE:To improve the workability and the safety of an actuator by using a hydraulic detent mechanism which works to hold a control lever at a detent position the lever is kept at the detent position and works to release the lever holding state when the lever kept at a position except the detent position is detected. CONSTITUTION:When a control lever 4 is set at a position except a detent position, the hydraulic reaction mechanisms 6 and 6' are actuated based on the detecting signal of a 1st detection means 7. Thus the operating reaction is applied to the lever 4 via the mechanisms 6 and 6' in accordance with the working state of an actuator 3. Then a hydraulic detent mechanism 8 is actuated when the lever is set at the detent position. Thus the lever 4 is held automatically and surely at the detent position by the hydraulic force. At the same time, the operating reaction produced by the mechanisms 6 and 6' are reduced when the lever 4 is kept at the detent position. Then the holding efficiency of the mechanism 8 is improved. As a result, both the workability and the safety are improved for an actuator.

IPC: H01L21/302
Filed: 1988-11-18
Abstract: PURPOSE:To effectively protect a solder bump against plasma and to prevent the bump from deteriorating by employing a platelike dry etching jig provided with a solder bump groove on its upper face. CONSTITUTION:A dry etching jig 9 is of a plate which is larger than a silicon wafer 1 and provided with a solder bump burying groove 91 corresponding to the array of solder bumps 4 at a substrate side at the center of the upper face of the plate. The discharge-machined wafer 1 is so placed with the device face disposed downward that the bumps 4 are completely buried in the groove 91, and then mounted on a lower electrode stage 83. Since no gap retains between both, plasma generated in a chamber in a dry etching step does not creep to both faces of the device of the wafer 1, and there is no apprehension that a plasma etching operation affects the bumps 4 directly. Thus, the bumps can be effectively protected against the plasma.
