摘要:
A self-contained hydraulic lash adjuster in which a sealing member is provided on the plunger for providing fluid tight seal between the plunger and a cylinder member. The sealing member is of a pair of lips both of which are in fluid tight contact with the cylinder member and are alternately deformed onto the cylinder member upon upward or downward movement of the plunger. During movement of the plunger, fluid-tight seal between the plunger and the cylinder member is assured with a little sliding friction therebetween.

A magnet structure and the like are provided, which can reduce the labor required to make a magnet design for producing a tunnel-shaped leakage magnetic field for plasma confinement in a well-balanced manner over an obverse surface of a target, based on a quadridirectional magnetic field produced by magnetic interaction between plural magnets. The magnet structure (110) includes: inner and outer magnets (10 and 13) positioned at a reverse surface side of a target (20) to have different magnetic moment orientations for producing a first magnetic force line reaching an obverse surface (20A) of the target (20); a pair of intermediate magnets (11 and 12) positioned at the reverse surface side of the target (20) and between the inner and outer magnets (10 and 13) to have different magnetic moment orientations, for producing a second magnetic force line acting to cancel a widthwise magnetic flux density component which is produced by the first magnetic force line; and a magnetic member (24) positioned at the reverse surface side of the target (20) to guide the second magnetic force line emanating from an end surface of one of the pair of intermediate magnets (11 and 12) into an end surface of the other, the magnetic member (24) being configured to produce a magnetic force line reaching an intermediate point in a thickness direction of the target (20) in association with the inner magnet (10) or the outer magnet (13).

摘要:
A cooling fan to be located between an internal combustion engine and a radiator and rotatingly driven from a rotational shaft of the engine. The fan includes a plurality of blade elements radially projecting from a boss portion and a cylindrical ring formed at the outer ends of the blade elements coaxially with the boss portion. In each blade element, a base line, which is drawn through a base point located on a chord of blade between leading and trailing edges of the blade element at a distance of 40% from the leading edge in percentage to the length of the chord, describes a straight or moderately curved line from the inner to the outer end of the blade element, which is inclined rotationally forward of a radial line passing through the base point at the inner end of the blade element. This fan construction produces air flows containing axial and radial components of velocity to increase the air flows through the radiator irrespective of the existence of the internal combustion engine on the downstream side of the fan. Maximum air flow is obtained by projecting the trailing edge of the outer end of each blade element from the trailing edge of the above-mentioned ring by a length corresponding to 1/3 of the chord length of the outer blade end.

A film deposition method and film deposition system for depositing a halogen compound film, capable of depositing such a film while suppressing abuse that occurs due to deficiency of a halogen element even if the halogen element is dissociated from a film material. The halogen compound film is deposited through a process including: evaporating a film material comprising a halogen compound by means of an evaporation source 3; ionizing the evaporated film material with a radio frequency power outputted from a radio frequency power supply unit 11 and supplied through a substrate holder 2; and causing the ionized film material deposit on the substrate 5. A bias voltage outputted from a bias power supply unit 12 and applied to the substrate holder 2 causes halogen ions dissociated from ions of the halogen compound to be incorporated into the film being deposited on the substrate 5.
