Abstract: A mouthpiece for use in upper endoscopy, including a main body of generally tubular shape internally providing a passage for receiving an endoscopic insertion tube and having a teeth support portion on the outer periphery of the passage portion. The internal passage in the main body is provided with a partition plate, thereby dividing the internal passage into an upper passage for introduction of an endoscopic insertion tube and a lower passage adapted to receive and hold a patient's tongue in such a way to restrict its movements.

Abstract: A turbocharger for an internal combustion engine, in which a bearing having excellent abrasion resistance without generating a black corrosion product in a high-temperature oil environment is provided. As bearing materials of a turbocharger, a copper alloy material containing, as main components, Cu, Zn, Al, Mn, and Si is employed. The elongating direction of an Mn—Si compound crystallized in the alloy material is set to the axial direction of a rotary shaft with respect to a radial bearing and is set to the direction perpendicular to the rotary shaft with respect to a thrust bearing.

Abstract: In a three-dimensional image scanner, a grating projection type moire topography is used, so as to capture three-dimensional form information of an object to be measured easily in a short time with a high degree of freedom in measurement. Also, a heat-insulating partition comprising at least two partition walls forming a cooling/heat-insulating path is disposed between a light source and a heat-sensitive section, so as to effectively inhibit the heat generated by the light source from being transmitted to the heat-sensitive section. The three-dimensional form information of the object is captured by a measurement head 12 having a function as a grating projection type moire device.

Abstract: A variable geometry turbocharger in which a bill-like projection portion is arranged in a part of an outer periphery of a flow passage spacer, and the projection portion is protruded to a turbine rotor side at a predetermined angle or the projection portion is movably provided. Alternatively, a rod-like member is arranged in a part of an outer periphery of a flow passage spacer and the rod-like member is arranged so as to be adjacent to the turbine rotor side at a predetermined angle. Alternatively, a guide vane in which a leading edge side of a rotational shaft is eliminated is arranged in a part of an outer periphery of a flow passage spacer and the rotational shaft is arranged so as to be adjacent to the turbine rotor side at a predetermined angle.

Abstract: There is disclosed a supercharger for an engine in which intake air is increased in pressure by the use of exhaust gas flowed into the supercharger from the engine, and is fed to the engine. An impeller 2, having a plurality of blades formed on an outer peripheral portion thereof, is received within a casing 1, and a ring-like fluid passage is formed around the plurality of blades, and a first partition 3 and a second partition 4 are provided in the fluid passage to divide this fluid passage into two fluid passages, that is, an exhaust gas passage 6 and an intake air passage 9. There is provided a fluid machine construction for causing the exhaust gas of the engine to flow into and out of the exhaust gas passage, and for causing the intake air to flow into and out of the intake air passage.

Abstract: A glass unit such as a binocular or monocular in which an object to be observed is viewed under magnification is made to display a map image, whereby the observer's own position can be specified on the map image without an atlas being opened. Based on a self-position data input from a GPS unit (21), a CPU (31) transmits map image information near its own position from a topographic map database (23) to a CG buffer (39) by way of a memory (25). On the other hand, based on the self-position data, a mark or character indicative of its position on the map image is generated by a mark character generating unit (35) so as to be superimposed onto the map image from the CG buffer (39), whereby a composite image thus formed is displayed by an LCD within a housing (10) so as to be viewed within the visual field of the glass unit.

Abstract: In an observing apparatus such as a binocular or monocular for viewing an object to be observed, a target position for observation is computed on the basis of own position information, azimuth information, and distance information to the observation target; and thus computed result is displayed within a visual field, whereby the target position for observation is determined correctly and rapidly. Based on an electric wave signal from a GPS satellite (50), the own current position is detected (S1). From an azimuth detection sensor (27) and a depression and elevation angle detection sensor (29), azimuth data and depression and elevation angle data from the own current position to the sufferer direction is detected (S2). From a topographic map memory (25), topographic map information near the own position is read out (S4). This map information includes data of absolute coordinates for each position of the topographic map.

Abstract: An image stabilized optical system includes a casing, an objective system, an eyepiece system, a gimbal connected to the casing via a shaft and capable of oscillating, an erect prism attached to the gimbal, a motor attached to the gimbal, an inertial rotor supported by a rotating rod of the motor, and a damper attached to the gimbal. The damper includes a viscoelastic member and has a first end attached to the gimbal and a second, free end spaced from the casing and the shaft. An image can be highly stabilized by efficiently suppressing in the damper vibrations (resonance) generated in the gimbal. Further, size, weight, and cost reductions, and easy manufacture of an image stabilized optical system are attained.

Abstract: A microfilm reader which has an optical system for magnifying and projecting an image recorded on a film contained a cassette onto a viewing screen mounted on a pivot shaft of a casing having a generally rectangular flattened box-like configuration of the microfilm reader for folding and unfolding movement comprises a cassette holder, a microfilm driving device for transporting the microfilm so as to place a frame of the microfilm of which an image is to be projected, a reflection mirror supported by the casing for sliding movement so as to be foldable in order to turn the projected image toward the viewing screen, a top cover mounted on and supported by the casing for folding and unfolding movement which is slidably engaged with a top end of the viewing screen so as to define a dark space behind the viewing screen in cooperation therewith when the viewing screen is unfolded and to cover and protect the viewing screen when the viewing screen is folded, and linking device interconnecting the viewing screen and
