Title: Electrostatic actuator
Inventor: MATSUZAKI KAZUNARI
IPC: H02N1/00
Filed: 1993-09-13
Abstract: PURPOSE:To obtain a electrostatic actuator which is assembled easily without an error with reference to a deceleration ratio by a method wherein the inside diameter of a stator is adjusted by the adjusting electrode of the stator by making use of an electrostatic attraction force. CONSTITUTION:Adjusting electrodes 144 and 113, 114 and 123, 124 and 133, 134 and 143 are arranged respectively on opposite faces at gaps G1 to G4 between segments for a stator 1. When a voltage is applied across the electrodes 144 and 113 at the gap G1 and across the electrodes 124 and 133 at the gap G3 at this time, the inside diameter of the stator 1 shrinks in the right and left directions in the figure by an electrostatic attraction force generated between the electrodes. When a voltage is applied across the electrodes 114 and 123 at the gap G2 and across the electrodes 134 and 143 at the gap G4 in the same manner, the inside diameter of the stator shrinks in the up and down directions in the figure by an electrostatic attraction force generated between the electrodes. Consequently, the inside diameter of the stator is changed as a whole. Since the electrostatic attraction force is in proportion to the square of the voltage, the inside diameter of the stator can be adjusted arbitrarily by changing the voltage which is applied.

Abstract: PURPOSE:To make thickness of films formed on wafers uniform, by providing with reaction gas spouting openings through a wafer-positioning stand having a basket thereon, with each opening located between the respective wafers, so that the reaction gas can pass along the respective wafers. CONSTITUTION:Reaction gas is supplied from a supplying port 13 through a manifold 12 into a pressure-reduced CVD vessel 11, that is a reaction gas passage 15 in a wafer-positioning stand 14, and then from the passage 15 the gas is spouted along the face of each wafer 6 through each reaction gas spouting opening 16 defined between the respective wafers 6. The wafers 6 which are arrayed in parallel, are slanted in a wafer basket which is placed on the wafer- positioning stand 14. The reaction gas which is introduced into the stand 14 in the vessel 11, is spouted uniformly from the spouting openings 16 in the stand 14 through the gaps between the respective wafers 6 as shown by the arrow in the figure. Accordingly, since all the gaps between the wafers have the same configuration, flow rate of the reaction gas passing through each gap becomes approximately uniforms so that thickness of films formed on wafers 6 can be uniformed.
