Filed: 1988-07-21
Abstract: PURPOSE:To prevent electrolyte from flowing to a caulk sealing portion and stabilize characteristics by a method wherein capacitor elements made of active carbon and separators are housed in a metal case having a pore, then an electrolytic solution is injected and impregnated, and this pore is sealed. CONSTITUTION:Two active carbon electrodes 13 and a separator 14 are positioned within a metal case 12 in the lower side. An upper-side metal case 11 having a pore 16 is incorporated in the metal case 12 via a sealing member 15 made of an electric insulator and jointed by caulking the peripheral edge of the case 12.

Filed: 1997-07-09
Abstract: PROBLEM TO BE SOLVED: To support a supported object at the same position and with the same force even with the variation of such environmental conditions as temperature. SOLUTION: A supported object (reflection mirror) 10 is supported with a support bellows 16 inside which work fluid is sealed and a back pressure bellows 18. The bellows 16 and 18 are connected with piping to the outers 36a and 37a of double bellows 36 and 37 respectively inside which work fluid is sealed and form a support system and a back pressure system. The inners 36b and 37b are connected to volume control tanks 40 and 41 inside which work fluid is sealed and forms a volume compensation system. When environment temperature rises, thermal expansion increases the volume of the outers 36a and 37a of the double bellows. Due to the volume increase, the thermal expansion of the work fluid in the support system and the back pressure system is absorbed and the supported object is supported at the same position and with the same force.
