Abstract: PROBLEM TO BE SOLVED: To surely prevent the leakage of light, to prevent the buckling of a bellows with secular change, and to accurately hold the positioning of a moving body by housing and arranging the bellows between two loops and setting a space between two loops nearly to dimension nearly equal to height attained at the time of folding the bellows. SOLUTION: A bellows 1 is elongated and contracted with the movement of a lens base 9 because it is interposed between the light shielding plates 16 and 17 of the lens base 9 and sticking parts 18 and 19 on a driving part side and a driven part side. The bellows 1 is housed on the inner surface side of a loop member 14 and guided by the member 14, so that the bellows is easily elongated and contracted without buckling. Thus, the lens base 9 is moved to a specified position. The gap is formed to have the dimension nearly equal to the height attained in the case the bellows 1 is the most contracted, and the bellows 1 is guided by the gap. Therefore, the bellows 1 is prevented from being buckled and deformed at the time of moving the lens base 9 back and forth.

Abstract: PURPOSE:To effectively isolate a material to be treated from a clamping member by operating a force for isolating the material to be treated from the member when the holding state of the material to be treated is released from a placing base and the member. CONSTITUTION:RF power from a RF power source 40 is applied between an upper electrode 10 and a lower electrode 30, etching gas is introduced through the electrode 10 to induce a plasma between the electrodes 10 and 30 to etch a wafer 42.

Title: Hot water boiler
Inventor: YABUUCHI KATSUHIRO
IPC: F24H1/22
Filed: 1988-04-13
Abstract: PURPOSE:To reduce a noise in case of performing a combustion at a hot water boiler and an ignition at the hot water boiler by a method wherein a range of variation of CO2 is restricted to a variation of anti-air pressure and the number of revolution of a fan of a blower is made to a low number of revolution in response to a low amount of consumption of oil. CONSTITUTION:In case that an anti-air pressure applied to a discharging port 7 is low, a burner 3 shows a combustion at the number of revolution of a fan of a blower 2 shown at a curve A. When the anti-air pressure is 15mmAq, for example, a burner 3 and a pressure sensing device 10 arranged at a cavity part of the discharging port 7 are turned ON. The number of revolution of a fan of the blower 2 is increased and the operation is moved to a curve B. When the anti-air pressure is decreased to show a value of 12.5mmAq, the pressure sensing device 10 is turned OFF to decrease the number of revolution of a fan of the blower 2 and moved to the curve A. In this way, the anti-air pressure at the discharging port 7 between the curve A and the curve B is detected; thereby, the number of revolution of the fan of the blower 2 can be varied optionally or in a stepwise manner. Since the anti-air pressure is placed at a lower position, the number of revolution of the fan at the blower 2 decreases and so a level of noise during combustion and combustion ignition is quite low.
