Title: Displacement enlarging structure for piezoelectric actuator
Inventor: YAMAOKA FUMIYUKI
IPC: H01L41/09
Filed: 1987-01-07
Abstract: PURPOSE:To reduce the cost, and to improve the durability and the reliability of displacement enlarging structure for a piezoelectric actuator by attaching a solid elastic member as a filler for enlarging the displacement of the actuator in the operating chamber of the actuator to remove a sealing structure, thereby simplifying the structure. CONSTITUTION:When a driving voltage is applied by a harness 12a to a piezoelectric actuator 12, an axial displacement occurs by an electrolysis induction strain in the actuator 12 to increase its whole length. This displacement causes an input side piston 15 to an operating chamber 19, a solid elastic material 20 is deformed to be moved into an output side cylinder 17, thereby axially displacing an output side piston 18 against the pressing force of a spring 21. The material 20 is deformed by the depression of the piston 15, but does not change its volume due to noncompressibility. Thus, the displacement of the piston 15 is enlarged by the sectional area ratio of the cylinder 14 to the cylinder 17, and output as the displacement of the piston 18.

Abstract: PURPOSE:To obtain a solid-state image-sensing element which prevents sensitivity from dropping and permits easy read-out of electric charge by making a highly concentrated p-type diffusion layer of a photo diode surface shallow. CONSTITUTION:A p-well diffusion layer 2, a gate oxide film 3, a gate electrode 4 and a photo diode n-type diffusion layer 6 are formed, and the gate oxide film 3 on a photo diode is removed by means of dry etching or wet etching with an interlayer oxide film 5 on the gate electrode used as a mask.
