Provided is a seal structure, according to the present invention, for sealing opposite surfaces of flanges between adjacent tail ducts, which can be prevented from being worn or aged deteriorated due to a thermal deformation in a high temperature atmosphere or vibration of a gas turbine combustor, and which can maintain a satisfactory sealing function for a long time. The seal structure is characterized in that recess grooves are formed in opposed surfaces of adjacent flanges at the outlet end of tail ducts, striding between the opposed surfaces, a seal assembly composed of a seal member and a leaf spring is inserted in the recess grooves, the seal member has a pair of continuous beads which are arranged facing the inner surfaces, on the combustion gas passage side, of the recess grooves, striding between the opposed surfaces of the flanges within the recess grooves, the leaf spring is arranged so as to be contact with the seal member within the recess grooves so that the beads are pressed against the surfaces on the combustion gas passage side by the resilient force of the leaf spring so as to create seal surfaces.

A pump for carrying supercritical COfluid or liquid COcapable of securing reliability by optimizing a bearing part. An angular ball bearing () comprises an inner ring (), an outer ring (), balls () held therebetween, and a cage () holding the balls (). Both the balls and the inner and outer rings are formed of a ceramic to form a totally ceramic bearing. Also, the cage () is guided by the outer ring or the inner ring. Specifically, for example, when the cage is guided by the inner ring, the inner peripheral surface () of the cage () opposed to the outermost peripheral surface () of the inner ring () is guided by the outermost peripheral surface () of the inner ring ().

A radioactive-material container includes a container body that shields nuclear radiation, which includes a cavity that stores a basket containing a recycle fuel assembly, a lid that covers the cavity, and a metal gasket that includes a sealing area that makes a physical contact with the container body and the lid. The sealing area has a specific shape that disperses tightening stress acting on the metal gasket for a sealing.

In a vacuum housing (1), an inner duct (17) is disposed. Quadrupole magnets (superconducting coils) (4) is placed around the inner duct (17) is excited by a DC power supply (10). Quadrupole magnets (4) are cooled by liquid helium contained in a helium housing and outer tubes (2, 3) and is brought into a superconducting state. Pulverized coal X is ejected together with air Y from a header (11) through piping (12) and a valve (13) to a baffle plate (14). Pulverized coal is made to fall into the inner duct (3). Paramagnetic materials such as ash are attracted by magnetic force to the tube and are then collected by a collection tube (26). Combustible diamagnetic materials are collected by a combustible collecting tube (18) extending in the central axis. Intermediate materials are collected by an intermediate collection tube (23) and are put back to the head (11) through a bypass tube (25). There are no mechanical parts in the inner duct (3). Consequently, rotation loss and eddy-current heating are prevented.

A noble solid electrolyte fuel cell includes a generating layer (5), an interconnector layer (9), and a support layer (10) disposed between the generating and interconnector layers. The interconnector layer comprises a fuel electrode (6), an interconnector material (7) and an oxygen electrode (8). The support layer (10) forms a fuel passage and an oxidizer passage, and supporting rods (15, 102) for gas sealing are disposed at both ends of the support layer. A sealing film (110) is cemented to the contact surfaces of the supporting rods (15, 102) between the generating layer and the interconnector layer, and this sealing film becomes soft or half melted during the operation of the fuel cell. This construction provides improved cell performances due to better sealing of gases even under large temperature differences. The use of finer particles near the surface of the solid electrolyte only is also disclosed.

This invention provides a drawing machine for pinching and stretching a film-like material of the type having rails installed extending from an inlet section to the outlet section and returning in the opposite direction from the outlet section back to the inlet section of the drawing machine. There is a clip propelling unit moving on the rails for pinching and stretching the film-like material, and elements for generating mutually repelling magnetic fields between the rails and clips, whereby the clips are movable in the non-contact state while floating from the rail guide surfaces. Thus, no foreign substances are generated, cleanliness of products is enhanced, no noise is generated, the work environment is improved, energy is saved, and highspeed operation is attained.

An electron beam working apparatus for cylindrical workpieces having a circular working line is improved so that a volume of a vacuum chamber to be maintained can be minimized and the vacuum chamber may not contain a contamination source such as a driving motor. In order to achieve the improvements, two disk-shaped partition plates having inflatable annular seal members disposed along their respective outer peripheral surfaces are placed inside the cylindrical workpieces respectively above and below the working line with said seal members pressed against the inner peripheral surfaces of said cylindrical workpieces to form a first vacuum chamber surrounded by said two partition plates and the inner peripheral surfaces of said cylindrical workpieces. Two annular fixed chamber wall members having inflatable annular seal members disposed along their respective inner peripheral surfaces are placed outside the cylindrical workpieces respectively above and below said working line with said seal members pressed against the outer peripheral surface of said cylindrical workpieces and an annular rotary chamber wall member provided with an electron beam gun is rotatably provided around the two annular fixed chamber wall members so that the inner peripheral surface of the former may make slide contact with the outer peripheral surfaces of the latter via seal members to thereby form a second vacuum chamber surrounded by the outer peripheral surfaces of said cylindrical workpieces, said two annular fixed chamber wall members and the inner peripheral surface of said rotary chamber wall member.
