Title: Etching method
Inventor: NAKAJI YORIO
IPC: C23F1/00
Filed: 1985-05-23
Abstract: PURPOSE:To form exactly a fine through-hole at a low cost by superposing two base material sheets on both surfaces of which an etching resistant pattern having the intended aperture parts are formed and etching successively the intended aperture parts on the inside and outside surfaces. CONSTITUTION:The etching resistant patterns 11, 12 having the intended aperture parts are formed on both surfaces of the base material sheets 10. Two sheets thereof are superposed and are freely strippably adhered by an adhesive agent 13 to form a laminate 15. An etching liquid is sprayed to the laminate 15 from the upper and lower directions to half etch largely the aperture of the etching pattern 12 and to form a recess 19. The adhesive agent 13 is then stripped and the aperture of the pattern 11 is half etched by the etching liquid to form a recess 24 so as not to arrive at the recess 19. The recesses 19, 24 are simultaneously etched to form the through-hole 28 and thereafter the patterns 11, 12 are removed by a solvent. The base material sheet 10 having the desired fine hole 28 is thus obtd.

Abstract: PROBLEM TO BE SOLVED: To facilitate the regulation of exciting force with a simple structure and to exhibit a regularly stable damping effect according to the change of pneumatic pressure or the magnitude of vibration by providing a capacity regulating means for changing the capacity of a working air chamber for adding the exciting force between two mounting members by the internal pressure change. SOLUTION: Since the negative pressure force of a negative pressure source 19 is increased in the stoichiometric operation of an internal combustion engine, the partitioning rubber plate 47 of a switching air chamber 51 is sucked to a bottom metal fitting 37 side against a coil spring 55 to increase the capacity of a regulating air chamber 53 communicating with an exciting air chamber 63. The pneumatic pressure fluctuation extends to a working air chamber (the exciting air chamber 63, or exciting air chamber 63 and the regulating air chamber 53) according to the switching of a selector valve 81, and the axial exciting force also extends to an exciting plate 59 forming the wall part of a pressure receiving chamber 77.  Consequently, the pressure change extends to a pressure receiving chamber 77, and a relative exciting force is transmitted between two mounting metal fittings 13, 15 through a non-compressive fluid sealed therein to exhibit a damping effect.
