Title: Washing method for solid electrolytic pipe
Inventor: FUJII MICHIMASA
IPC: B08B3/04
Filed: 1988-06-07
Abstract: PURPOSE:To prevent the resistivity of sodium ions included in each of electrolytic pipes from increasing, by specifying the quantity of water contained in a washing liquid for use in a washing process of the pipes. CONSTITUTION:The quantity of water compounded in washing liquid for use in a washing process is set less than 0.5% and the liquid is contained in a washing vessel 1, then a plurality of solid electrolytic pipes 3 made of beta-alumina porcelain is made to sink into the liquid with openings thereof facing downwardly so as to wash the pipes therein.

Filed: 1978-11-14
Abstract: PURPOSE: To simplify the structure and provide a compact device by providing the shouldered bore inside the main piston with the stepped piston equipped with the valve device for making brake oil in auxiliary pressure chamber flow into the main pressure or feeding chamber.  
     CONSTITUTION: The shouldered bore 37 installed in the main piston 9 is provided with the stepped piston 43 equipped with the valve device (consisting of valve chamber 48, lip seal 50, 51, etc.) for making brake liquid in auxiliary pressure chamber 12 flow into main pressure chamber 16 or feeding chamber 15.

Abstract: PURPOSE:To easily evaluate the amount of dust generated in an apparatus, by storing the inspecting result data in the inspection of foreign matter performed plural times with respect to the same article to be inspected under the same condition in a re-inspection mode and comparing the inspection result data of each time. CONSTITUTION:A foreign matter inspection apparatus is constituted so that the surface to be inspected of a wafer 30 is irradiated with laser beams of S-polarizing laser oscillators 36, 38 to automatically inspect foreign matter. Reflected laser beam is supplied to optical systems 54, 46, 58, 60 common to an inspection system 50 automatically detecting foreign matter and a microscope 52 for the visual observation of the wafer. When the amount of dust generated in the apparatus is much or scanning is unstable, the irregularity in the number of foreign matters detected in the inspection of foreign matter at each time becomes large and, therefore, the inspection result data in the inspection of foreign matter performed plural times with respect to the same article to be inspected under the same condition are compared in both inspection modes. That is, the reproducibility of the inspection results is checked.

Abstract: PURPOSE: To prevent cyclic velocity changes of an actuator by providing a compensating element to inhale and exhale in commensuration to pressure changes of the actuator in a line to link between a pilot chamber of a pressure compensating valve and an antecedent position of the actuator.  
     CONSTITUTION: When pressure of main current fluid 37 has been aggrandized, fluid pushed out of a chamber on the left side of a cylinder 30 is worked into a spool 23, and a pilot chamber 26 at the left extremity, which pushes said spool 23 in the right direction, pressure rise of the main current fluid 37 is repressed, to the contrary, when the pressure of the main current fluid 37 has been dropped, right movement of a piston 32 by a spring 33 reduces the pressure in the pilot chamber 26, left movement of the spool 23 prevents larger reduction of the pressure of the main current fluid 37. In consequence, width of pressure changes of the main current fluid 37 becomes smaller, to be able to prevent cyclic velocity changes of the first actuator 21.
