Filed: 1984-09-07
Abstract: PURPOSE:To miniaturize the captioned mechanism as well as facilitate assembly work by providing a suspension device including a suspension release member communicated wit another suspension device interposed between a cam and an air intake/exhaust valve, and forming said suspension release member with a form storage alloy. CONSTITUTION:In interrupting a specific cylinder by stopping the operation of air intake/exhaust valve 10 of said cylinder in the case for example of an engine operated at low rpm under low load, with a switch 32 being switched on to conduct a current through an electric heater 31, a coil-shaped suspension member 30 is heated to restoration set temperature or more of a form storage aloy constituting said suspension member. Hereby, the suspension member 30 is elongated, and a check ball 24 is pushed left against a suspension release spring 34 and a check ball spring 25 for opening an orifice path 20. Thereupon, when a body 6 of a suspension mechanism 5 is pushed down by operation of a cam 2, pressure oil 8 is discharged via passage means 13 to 15 and a second hydraulic chamber 19, etc., and thus no displacement of the cam 2 is transmitted to the intake/exhaust valve 10 to result in the intake/exhaust valve 10 being made a non-operation state.

IPC: H01L21/027
Filed: 1997-07-14
Abstract: PROBLEM TO BE SOLVED: To provide a method for manufacturing a semiconductor device, through which an insulating film containing moisture or an organic solvent can be worked with high precision and ease. SOLUTION: A low dielectric SiO2 film 14 as an interlayer insulating film is formed by causing a reaction between Si(CH3 )H3 (monomethylsilane) and H2 O2 by an LP-CVD method (low pressure-chemical vapor deposition). When the low dielectric SiO2 film 14 is selectively etched with a mask of resist 16 for a pattern of via holes, plasma etching is performed with a large amount of moisture contained in the film without performing annealing. At this time, a large amount of H2 O is desorbed in gaseous form, as indicated by arrows 20 from the sidewalls of the low dielectric SiO2 film 14 exposing in the via holes 18 and prevents radicals in plasma from approaching the sidewalls of the low dielectric SiO2 film 14. Accordingly, isotropic etching of the sidewalls of the low dielectric SiO2 film 14 by radicals is inhibited, and bowing of the cross-section of the sidewalls of the low dielectric SiO2 film 14 is prevented.

Abstract: PROBLEM TO BE SOLVED: To reduce the quantity of bending in the right and left directions from the direction of wiring of a loop strained by cooling wire just annealed in such a way as to make the cooling speed to be represented by a specific formula a specific value or less, using a solid cooling substance kept at a specific temperature or lower. SOLUTION: A pulley 12 as a solid cooling substance is kept at 20 deg.C or lower. Along with it, a cooling speed represented by cooling speed ( deg.C/sec) = (wire speed) × (atmospheric temperature in an annealing furnace - solid cooling substance temperature)/(distance from the exit of an annealing furnace to a solid cooling substance) is made to be 1,000 deg.C/sec or more. Consequently, it becomes possible to reduce the quantity of bending of a strained loop in the right and left directions from the direction of wiring, even in the case of a long loop and high wiring density. Accordingly, it becomes possible to prevent the short-circuiting between wires caused by the multiplication of pins of a semiconductor device.
