A first channel is formed in the side of a first diffusion plate which is on that side of a gas inlet tube and a recess is formed in the side which is on that side of an electrode plate. The first channel and the recess communicate with each other through a plurality of inlet ports. The first channel and the inlet ports form a gas flow passage L which leads to the recess from the gas inlet tube. As a process gas supplied from the gas inlet tube passes through the gas flow passage L, it is supplied, dispersed, to a hollow portion formed between the recess and the electrode plate.

In the film forming method of the present invention, a substrate is first received in a processing vessel. Then, a film-forming gas including an organic silicon and an additive gas including a paraffin hydrocarbon gas and/or a hydrogen gas are introduced into the processing vessel, and the film-forming gas and the additive gas are then converted into plasma. In this manner, a carbon-hydrogen-added silicon oxide film (SiCOH film) is formed on the substrate. Alternatively, the film-forming gas is first introduced into the processing vessel containing the substrate and is then converted into plasma to form the SiCOH film on the substrate. Subsequently, the additive gas is introduced into the processing vessel and is then converted into plasma to post-treat the substrate having the SiCOH film formed thereon.

A processing method of a substrate includes: a step of forming an Si—C based film and a resist film in turn on an objective film to be etched that has been formed on a substrate; a first etching step of etching the Si—C based film making use of the resist film as a mask; and a second etching step of etching the objective film to be etched making use of the resist film and the Si—C based film as a mask. The processing method further includes a peeling-off step of peeling-off the resist film at a desired timing. The peeling-off step includes a preparing step of preparing an organic solvent as a release agent, and an applying step of applying the organic solvent to the resist film.

A swiveling work machine includes a traveling apparatus, a swivel base mounted on the traveling apparatus to be pivotable about a vertical axis, a hood disposed at a rear portion of the swivel base, the hood accommodating therein an engine, a support frame being disposed across over the engine, and a ROPS having a front end thereof fixed to the swivel base and a rear end thereof fixed to an upper portion of the support frame. The support frame includes a front leg member disposed on one lateral side of the ROPS, the front leg member extending to vicinity of a position forwardly of the swivel base.
摘要:
An alternating current generator for vehicle has a permanent magnet in the rotary field core unit. Providing such magnet is effective to reduce leakage magnetic flux and the size of the machine. In order to magnetize the magnet without trouble caused by machined chips or iron powder, the magnet is magnetized after the rotary field core has been machined. While the magnet is magnetized in a short period by a pulse current, the field coil is short-circuited. The field coil is subjected to magnetizing flux passing therethrough and generates short-circuit current and, consequently, counter magnetomotive force, which prevents leakage of the magnetizing flux.
