An object of the present invention is to provide an ingot wherein occurrence is prevented when an electroslag remelting method is used for producing a large ingot and which a super alloy is sensitive to segragation. According to the present invention, the electrode for electroslag remelting method has a hole formed along an axial direction in the core of an electrode. Therefore, the molten pool is made shallow so that flat and segregation is prevented from occurring. Consequently, an ESR ingot of good quality is accomplished with an excellent surface and is free from segregation. Moreover, an electrode melting rate is increasing and efficiency is improved.

In a toner image fixing device, there are provided an endless belt being looped up around a heating roller and a conveyance roller, a pressure roller for pressing a sheet having a toner image onto the heating roller with the endless belt intervening between the pressure roller and the heating roller. A sensor is disposed inside the loop of the belt so as to come in contact with the heating roller, for detecting the temperature of the heating roller. The fixing temperature for the toner image is controlled on the basis of the temperature of the heating roller detected by the sensor. A first nip region is formed on a pressing portion located between the heating roller and the fixing roller. A second nip region is formed between the belt and the fixing roller, continuing from the first nip region but without contacting the heating roller.

A camera of a preliminary winding type in which a film in a patrone is previously taken out from the patrone to roll it round a spool and, each time one frame photographing is completed, the film is rewound into the patrone by one frame in photographing. The camera comprises a motor, a preliminary winding mechanism, a frame-by-frame rewinding mechanism, a focal length varying mechanism, first and second planetary clutch mechanisms, and an engagement mechanism for locking the first planetary clutch mechanism, and is capable of switching the power transmission to the preliminary winding, frame-by-frame rewinding and focal length varying mechanisms by changing the direction of rotation of the motor.

A printing head for ink-jet printing comprises at least one ink-flow passage in the form of a hollow chamber and at least one ink-jet nozzle coupled to the ink-flow passage. The hollow chamber has a substantially uniform depth over substantially the entire area thereof. Preferably, the head comprises at least two laminated sheet-like members, one of the members having a hollow formed therein to comprise the ink-flow passage, and the other of the members having at least one nozzle formed therein. The head further comprises a flexible wall in communication with the hollowed chamber and a piezoelectric transducer connected to the flexible wall for producing ink-jetting pressure changes in the hollow chamber. Also disclosed are multi-nozzle printing heads with the chambers arranged in a circular configuration, and stacked double and triple decker arrangements.

A flowcell for containing sample solutions is surrounded by an electric heater which is then surrounded by an isothermal frame having a large heat capacity, and a Peltier element serving as a cooling source is coupled with the isothermal frame. A heat delaying plate is arranged between the flowcell and heater and a temperature sensor is arranged between the flowcell and the heat delaying plate. The Peltier element is controlled in such a manner that the temperature of the isothermal frame is maintained substantially at a constant temperature lower than a predetermined temperature at which the sample solution is to be kept. The heater is controlled in accordance with a difference between the temperature of the sample solution and the predetermined temperature.

A semiconductor device is provided that includes wiring patterns on a substrate formed of an organic insulating film, and a semiconductor chip mounted on the substrate. A liquid crystal display panel and a PW board are electrically connected to each other with an anisotropic conductive adhesive. At least one surface of the insulating film is treated with a silicon coupling material. The silicon coupling material contains silicon (Si) at a surface element density of 0.5 atomic percent to 12.0 atomic percent on a surface of the insulating film.

It is an object of the present invention to provide a shooting apparatus which is thinner than a conventional shooting apparatus. A lens barrel is brought into an accommodated state from a shooting state by retracting at least one of lens groups constituting the shooting lens from an optical axis, and by bringing at least a portion of one of the other lens groups remaining on the optical axis or an image pickup element into a non-using state in which an opening is left opening at a predetermined opening diameter.

A cartridge loading chamber for IX 240 type cartridge (so-called APS cartridge) usually has a bottom lid. A lid of the invention has a function for detecting whether the cartridge exists in the cartridge loading chamber by installing a detecting mechanism on the lid which includes a projection member spring-biased and a electric switch made of a pair of metal leaves capable of switching on/off in association with movement of the projection member made by being pushed by the bottom of the cartridge when the lid is closed.

A decorative frame that may be made of metal is arranged at the periphery of a manual operation button, and the manual operation button with decorative frame are designed so that they may be fixedly attached to the exterior cover of a camera body within an opening in the cover. More specifically a structure of a manual operation button is disclosed that includes: a decorative frame having an exterior portion that will not fit within the opening and an interior portion that will fit within the opening; a manual operation button positioned within an inner periphery of the decorative frame; and a holding member that is installed within the camera body, with a portion of the holding member abutting the inside surface of the camera body exterior cover and a portion of the decorative frame abutting the outside surface of the camera body exterior cover so that the decorative frame and holding member, when assembled as a unit, envelope the rim portion of the opening so as to attach the decorative frame and the holding member to the cover. The holding member holds the manual operation button so that it may be depressed to various positions when operating the camera.
