Disclosed herein is a plasma processing apparatus that introduces a process gas into an airtight processing container, that applies a radio frequency power to generate plasma, and that conducts a plasma process to an object to be processed arranged in the processing container. The plasma processing apparatus includes: an electrode unit arranged in the processing container, the electrode unit having an electrode for applying the radio frequency power, and a space portion arranged in the electrode unit, the space portion insulating the electrode and the processing container from each other. The space portion communicates with atmospheric air outside the processing container.

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.

A digital signal error reduction apparatus of the present invention tracks and reduces both quickly changing errors and static errors in a digital signal which are caused by time variant multipath distortion, co-channel interference, and other transmission path interferences, including nonlinear distortion. A transversal filter is implemented for filtering the digital signal. A error detection device is implemented for calculating an error of the digital signal. A coefficient engine device is used for receiving the digital signal and the error, for extracting the error, and for updating a tap coefficient for the transversal filter so that the error is minimal.

Sheet transportation apparatus operating in an image forming system for xerographic printing employing magnetic toner. The inventive features of the sheet processing apparatus are directed toward smooth transportation and discharge of printing sheets sent through a system image printing unit, across a sheet transport guide, and through an image fixing and sheet transporting unit which finally discharges the printing sheets. The sheet transport guide dips downward and meets a sheet admission guide, having superficial resistivity lower than that of the sheet transport guide to reduce electrical repulsion of the leading edge of a transported sheet. The sheet admission guide guides each sheet into a nipping position of a heating/pressure roller pair as fixing rollers in the image fixing unit. The heating roller heater is designed to promote even heat emission axially along the cylindrical surface of the heating roller, counteracting unidirectional flow of cooling air in the system, ensuring smoothness in the image fixing, sheet-nipping transport of the printing sheet. Further, a gear train transmits power simultaneously to the fixing rollers, and to a discharge roller pair. A middle gear of the train is disengagable by a mechanism releasing the pressure roller from the heating roller, in turn releasing drive power engagement of the discharge rollers, so that a sheet-jam condition in the system is easily remedied.

A sealing part that is inexpensive and enable excellent durability to be secured without the need for a predetermined sealing space as would be required for a double sealing structure. A sealing part seals an inside of a reduced pressure vessel from an outside, in which a high-elasticity polymeric material-eroding eroding substance is present and which is comprised of a substrate processing apparatus carrying out predetermined processing on a substrate housed in the reduced pressure vessel. The sealing part has a radical sealing member and a vacuum sealing member. The radical sealing member is disposed on an inside side of the reduced pressure vessel and is resistant to the eroding substance. The vacuum sealing member is made of the high-elasticity polymeric material and is disposed on an outside side of the reduced pressure vessel. At least one refuge space is formed through at least part of the radical sealing member and at least part of the vacuum sealing member being separated from one another. The radical sealing member and the vacuum sealing member are fitted together.

A projector includes: first and second light blocking members adapted to partially block a light beam from a light source, and a drive section adapted to make the first and second light blocking members perform an opening and closing operation. When the corresponding first and second light blocking members are located at a maximum blocking state, with respect to an opening and closing direction of the first and second light blocking members perpendicular to a system optical axis, a first and second support sections support the first and second light blocking members at predetermined positions on the system optical axis side from intermediate positions corresponding to midpoints of areas between edge portions of the first and second light blocking members on the system optical axis side and parts, to which outer edges of the light beam to be blocked are input.
