Abstract: A fluid pressure cylinder. A first stepped section having a greater diameter than a cylinder chamber is formed at one end of a cylinder tube constituting a fluid pressure cylinder. A disc-shaped head cover is inserted into the cylinder chamber. The one end is pressed and plastically deformed by a staking jig to form a deformed section, and the head cover is affixed within the first stepped section by the deformed section. As a result of this configuration, the head cover can be more firmly affixed while the sealing effect between the cylinder tube and the head cover is ensured. This eliminates need for a seal means and an engagement means which is used to affix the head cover, and consequently, the number of parts can be reduced.

Abstract: The driven rotation axis, the driving rotation axis, the ACT lever, the driving pin, the rod, the driven pin and the WGV lever constitute a linkage. In order to consider the instrumental error caused by the linkage configuration, a link ratio is defined by the equation (Link ratio=(Lwg/Lact)*(sin ?/sin ?), wherein Lwg is a length of the WGV lever, Lact is length of the ACT lever, ? is an angle formed by the WGV lever and the rod, and ? is an angle formed by the ACT lever and the rod). The current value input to the DC motor is corrected with a correction coefficient is a value obtained by dividing an actual link ratio by a target link ratio.

Abstract: A technique for obtaining good film quality in forming a silicon-oxide-containing insulating film as a coating film on a substrate. A coating liquid containing polysilazane is applied to a wafer, a solvent in the coating liquid is volatilized, and then the coating film is irradiated with ultraviolet rays under a nitrogen atmosphere before performing a curing process. Thus, dangling bonds are likely to be formed at hydrolyzed portions in polysilazane. Since dangling bonds are formed in advance at portions in silicon to be hydrolyzed, productivity of hydroxyl groups is enhanced. That is, since an energy required for hydrolysis is reduced, the number of the portions remaining without being hydrolyzed is reduced even when the curing process is performed at a low temperature. Therefore, dehydration synthesis occurs efficiently, which increases a crosslinking rate and makes it possible to form a dense (good film quality) insulating film.
