A shield cover for an engine is provided to shield electric parts, in an engine wherein an engine body includes a crankcase having a plurality of cylinder bores. An intake chamber common to all of the cylinder bores is spaced away from the crankcase. The shield cover is made in one piece, making it possible to reduce the number of parts and also of the cost, and to achieve a generally compact configuration of the engine. A plurality of electric parts 47L, 47R, 62L, 62R, 64 are disposed around an intake plenum 49, and the plural electric parts 47L, 47R, 62L, 62R, 64 are covered with a shield cover 67 attached to the engine body 12 in such a manner as to cover at least part of the intake plenum 49.
摘要:
A harness outlet structure of an engine permitting a reliable shield at a harness outlet of the engine. The structure includes a wiring harness is clamped by a shield cover and an engine main body via a grommet bracket. The grommet bracket includes a groove having a width equivalent to the thickness of the shield cover disposed circumferentially between two flange portions of the grommet bracket. A harness overall for shielding the wiring harness is mounted externally on a proximal end of the grommet bracket. The harness overall is a shield outer jacket body formed from braided metal fibers. The harness overall is inserted over an outside of the proximal end of the grommet bracket until one end of the harness overall contacts the flange portion. The harness overall is then joined by a coupling ring.

The lower end of a filler tube is attached to a service hole formed on a cylinder block in a horizontally opposed engine on a rear side of the engine, e.g., on side opposite from which an output shaft projects. The filler tube is provided with an elbow at the lower end thereof, and the elbow is integrally formed with a hole cover. When one end of the elbow is inserted into the service hole and the hole cover is fixed to the cylinder block, the connection of the filler tube and closing of the service hole can be simultaneously accomplished. The filler tube extends upward and a cap is attached on the filler port at the upper end facing toward the vicinity of the lid provided on the cowl 20. The lid 21 is not deformed locally, and forms a curved surface continuing from remaining portion of the cowl 20.

An axial flow compressor includes: a rotor having a rotor vane; a first pressing member joined to one end surface of the rotor; a second pressing member joined to the other end surface of the rotor; a rotor shaft portion penetrating the first pressing member, the rotor and the second pressing member; and a nut which fixes the first pressing member and the second pressing member on the rotor shaft portion with the first pressing member and the second pressing member holding the rotor between. The rotor shaft portion is made of a material having a lower linear expansion coefficient than that of a material making at least a part of the rotor. The material making at least a part of the rotor may be aluminum or aluminum alloy.

An electrode having a gas discharge function, where the degree of freedom related to a maximum gas flow rate is abundant, an electrode cover member may be thinned, and a change of a gas behavior according to time is difficult to be generated in a processing chamber during gas introduction. The electrode includes: a base material having a plurality of gas holes; and an electrode cover member having a plurality of gas holes respectively corresponding to the plurality of gas holes of the base material in a one-to-one manner, fixed to the base material, and disposed facing a processing space in which the object is plasma-processed, wherein a gas hole diameter of the electrode cover member is larger than a gas hole diameter of the base material.

A substrate processing apparatus includes: a depressurizable processing chamber 11; a shaft 26 supporting a facing electrode 24 provided within the processing chamber 11 while allowing the facing electrode 24 to be movable with respect to a mounting electrode 12; a first ring-shaped bellows 31 concentrically installed at an outer peripheral portion of the shaft 26; and a second bellows 32 concentrically installed at an outer peripheral portion of the first bellows 31. The first bellows 31 absorbs a displacement of the facing electrode 24 with respect to a wall surface 13 at a penetration portion where the shaft 26 penetrates the wall surface 13 of the processing chamber 11, and seals the inside of the processing chamber 11 against the ambient atmosphere around the shaft 26. A ring-shaped gas flow path 35 is formed by the first bellows 31 and the second bellows 32.
摘要:
A material gas concentration control system for keeping a concentration of a material gas in a mixed gas constant comprising a tank to accommodate the material, an inlet line to input a carrier gas for evaporating the accommodated material into the tank, and an outlet line to output the mixed gas consisting of the material gas evaporated in the tank and the carrier gas, and further comprising a first valve arranged in the inlet line, a concentration measuring part that measures the concentration of the material gas in the mixed gas, and a concentration control part that controls an open degree of the first valve so as to make the measured concentration of the material gas measured by the concentration measuring part become the previously determined set concentration.
