Abstract: A static-pressure bearing apparatus that prevents vibrations, the apparatus including an orifice and a vent groove, such that a laminar-flow status may be maintained in the entire region of the routes of the ventilated pressurized gas. A stage equipped with the static-pressure bearing apparatus is also provided. The configurations, such as the shapes of the orifice 14, vent groove 11, and the exhaust groove 12, of the static-pressure bearing apparatus 1, are designed such that a laminar flow may be maintained in the entire region of the routes for ventilation of the pressurized gas. The vent groove 11 comprises the circular groove 11b and a plurality of distributing grooves 11a. The vent groove 11 is formed to be symmetrical about the centerline of the direction that the moving body 10 moves. The circular groove 11b is formed as a circle to surround the orifice 14.

Abstract: A device for damping runout vibration of a rotating shaft system at least including a rotating shaft and a rotating body rotatably supported by the shaft. A ring (24) is provided outside a bearing (23) fitted on a rotating shaft with a clearance between the ring and an outer ring of the bearing. A vibration damping mechanism includes, in order to suppress runout vibration of a rotating shaft system from the radially outside of the ring (24), a blade spring (25) compressed by a preload and a stopper (26) for setting an operation limit of the blade spring.

Abstract: A process for producing a ceramic sinter or inorganic film in which anisotropic particles or anisotropic crystals have been oriented; or a process for producing a bonded composite material which comprises a base sample and another material tenaciously bonded to a surface of the base. The processes are characterized by imposing a centrifugal force during buming (heating).

Abstract: It is an object to provide a method of manufacturing a porous medium having a grading porous structure, and there are provided a method of manufacturing a porous medium having a grading porous structure, comprising the steps of installing a sample consisting of a powder compact or a porous body in a rotating body, and heating the sample while applying a centrifugal force to the sample through high-speed rotation of the rotating body to produce a porous medium having a grading porous structure in which the pore size and the porosity change gradually by using the pressure grading in the sample arising through the centrifugal force, and such a method wherein the pore size and the porosity of the sample are predicted based on a linear shrinkage factor calculated through the equation:

Abstract: An apparatus for testing the thermal shock fracture strength of ceramics. The apparatus includes supporting means for supporting a ceramic test piece shaped as a rectangular parallelepiped at a first side surface thereof, force-detecting means for restraining a predetermined location of a second side surface of the ceramic test piece, the second side surface facing the first side surface, the force-detecting means and the supporting means restraining any deformation of the ceramic test piece when the second side surface of the ceramic test piece is heated, the force-detecting means being adapted to detect a force acting on the force-detecting means from the ceramic test piece, which tends to be deformed, but which deformation is restrained, means for moving the supporting means to press the ceramic test piece against the force-detecting means, and a heat-emissive element, which is an electric heater, for covering and heating the second side surface to cause a thermal shock in the ceramic test piece.

Abstract: A press apparatus for use in manufacture of a liquid crystal panel presses upper and lower glass substrates placed between a pressure-exerting plate and a pressure-receiving plate while a seal located around the glass substrates is being heated and melted. The pressure-exerting plate is supported by a pressure-transmitting plate through three load cells. The pressure-transmitting plate presses the pressure-exerting plate against the pressure-receiving plate through the load cells and thereby presses the glass substrates uniformly. When a difference between the detection values of the load cells exceeds a predetermined value, it is determined that the glass substrates are not being pressed uniformly and the pressing operations thus stopped.

Abstract: A method of forming from a sintering material slurry a shaped-body to be sintered having a complicated configuration. A mold is prepared using frames, a shielding member swollen with a solvent, and a filler including a substance formed of particles, and utilizing the action of vacuum. A sintering material slurry is poured into the thus prepared mold to form a shaped-body to be sintered.
