Title: Electrostriction element control device
Inventor: YAMAMURA MITSUGI
IPC: G05D3/00
Filed: 1983-11-18
Abstract: PURPOSE:To obtain the changed variable of an electrostriction element precisely by comparing a wafer driving variable by the electrostriction element which is detected by an eddy current type position detector with a driving variable specified by a microprocessor sequentially and driving the wafer until the difference of the compared values is included in an allowable error range. CONSTITUTION:When the wafer 4 is vertically driven by the electrostriction element 23, the driving variable is detected by air sensor nozzles 34-37 and the eddy current type position detector 22 and measured. The output of the detector 22 is converted into a voltage proportional to the displaced variable by a displacement/voltage converting circuit 48 and the voltage is outputted to a differential amplifier 45 and an A/D converter 47. The amplifier 45 compares the wafer 4 driving variable by the element 23 which is detected by the detector 22 sequentially with the driving variable specified by the micro-processor 40 to drive the wafer 4 until the difference is included in the allowable error range. Consequently, the surface of the wafer 4 can be positioned to a prescribed focus position accurately.

Abstract: PROBLEM TO BE SOLVED: To reduce the construction cost and to suppress environmental disruption by using T-shaped battens made of wood or an angular pipe in place of long battens for supporting the bottom face section of a thin steel sheet form made of a trough-like body with a nearly U-shaped cross section. SOLUTION: Since face sections 32 are erected from both side edges of a bottom face section 30 folded and formed with keystone-like waves, and the upper edges of the side face sections 32 are folded outward nearly horizontally as deck receivers 34 to integrally form a thin steel beam form made of a trough- like body with a nearly U-shaped cross section. A plurality of T-shaped battens 22 made of a square lumber or an angular pipe are arranged at a prescribed intervals below the bottom face section 30 in the width direction of the thin steel sheet beam form. A plurality of timberings 24 are erected at prescribed intervals blow the battens 22, and they are connected together to secure stability. When the battens 22 made of an angular pipe are used, they are fitted via a support metal fittings 40 made of a steel sheet.  Since reinforcing pipe supports of the support metal fittings 40 can be used semipermanently in place of expensive long square lumber, the construction cost is reduced, and environmental desruction can be suppressed.

A soln. of monochromate and (or) dichromate (e.g.: sodium dichromate), is introduced into the anode chamber of the electrolytic cell and is electrolyzed, by which the dichromate and chromic acid are produced. At this time, the chromate-contg. soln. of pH about 3 to 10 is continuously introduced into the cathode chamber during the electrolysis. As a result, the phenomenon that a small amt. of the compds. of the polyvalent cations, such as calcium ions and strontium ions, contained in the raw material precipitate on the cation exchanger membrane, make the function of the membrane lower and destroy the membrane is prevented.
