Abstract: The illuminating light transmitted by the light guide inserted through the elongate inserted section is projected out of the distal end surface of the inserted section. The illuminated objects pass through the respective pupils of the two objective lens systems arranged in parallel within the distal end section of the inserted section and their images are formed on the focal surface. The respective images are transmitted to the rear side by one common relay lens system. The transmitted final images are formed respectively on the image taking surfaces of the image taking devices. The respective images photoelectrically converted by the respective image taking devices are processed to be signals, are displayed in the monitor and are stereo-inspected through shutter spectacles.

Abstract: A scanning optical microscope apparatus includes a laser light source, an objective lens for condensing a laser beam emitted from the laser light source on a specimen, a scanning device for relatively scanning the specimen with a condensed laser spot, an imaging optical system for imaging light emanating from the specimen, a confocal stop placed at the focal point of the imaging optical system, and a plurality of photodetectors for detecting the light from the specimen, passing through the confocal stop. In this case, the scanning optical microscope apparatus includes a spectrum decomposing device for spatially decomposing a light beam passing through the confocal stop into a wavelength spectrum, and an array of light-deflecting microelements arranged, at least, in a direction of spectral decomposition and receiving and deflecting a part of the light beam decomposed into the spectrum toward any of the plurality of photodetectors.

Abstract: The illuminating light transmitted by the light guide inserted through the elongate inserted section is projected out of the distal end surface of the inserted section. The illuminated objects pass through the respective non-superimposed pupils of the two objective lens systems arranged in parallel within the distal end section of the inserted section and their images, which are not equal to each other are formed on the focal surface. The respective images are transmitted to the rear side by one common relay lens system having a single optical axis. The transmitted final images are formed respectively on the image taking surfaces of the image taking devices. The respective images photoelectrically converted by the respective image taking devices are processed to be signals, are displayed in the monitor and are stereo-inspected through shutter spectacles.

Abstract: A device for inputting a shape of an object includes a base mounted on the object, a flex detecting unit for detecting an amount of flex of the object, and a stretch detecting unit, coupled to the base and to the flex detecting unit, for detecting an amount of stretch between the base and the flex detecting unit which corresponds to an amount of stretch of the object. The stretch detecting unit includes a stretch mechanism which is expanded or contracted in accordance with the stretch of the object, and the amount of stretch of the object is detected based on a detected amount of stretch of the stretch mechanism. The flex detecting unit includes a member which is deformable in an amount corresponding to the amount of flex of the object, and the amount of flex of the object is detected based on a detected amount of deformation of the deformable member.

Abstract: A flexible, multilayered tube with superior chemical resistance, heat resistance, and airtightness, as well as superior flexibility and resistance of the inner surface to staining. The tube comprises a flexible, multilayered tube having a first layer comprised of a non-porous polytetrafluoroethylene structure and a second layer comprised of a porous polytetrafluoroethylene structure laminated onto the outer peripheral surface of said first layer. The tube is useful as a medical tubing and in particular useful as an endoscope tube.

Abstract: A grasping forceps for an endoscope including a flexible insertion section, an operating wire adapted to pass through the insertion section and to be advanced and retreated in accordance with the operating of an operating section connected with a hand-end side end portion thereof and at least four elastic grasping members of different lengths arranged at the leading end portion of the operating wire and having the habit of flexing such that leading end grasping portions formed at their leading end portions respectively spread outwardly from the central position of the insertion section.

Abstract: The radioactive ray detecting therapeutic apparatus of the present invention has an insertable part to be inserted toward an affected part. A therapeutic apparatus for treating the affected part, and a radioactive ray detecting apparatus for detecting radioactive rays discharged out of the affected part and providing signals by which to direct the therapeutic apparatus to the affected part, are provided in the tip part of the insertable part.

Abstract: In a vibration wave motor having a vibration member and a movable member press-contacted to the vibration member so as to be rotatably driven thereby, the vibration member is supported by a plurality of elastic supporting arms and the elasticity of the supporting arms produces a frictional force between the vibration member and the movable member.

Abstract: This electronic endoscope has an insertable part having an observing window on the side of a tip part extended forward of the insertable part. The solid state imaging device is to receive an entering light from the above mentioned observing window and is arranged so as to intersect substantially at right angles with the axial direction of the above mentioned insertable part. Contents are arranged on the opposite observing window side of this solid state imaging device. This solid state imaging device is provided with wire bonding parts on the side different from the side on which the above mentioned contents are arranged.

Abstract: A calculus disintegrating apparatus includes first and second electrodes which are arranged at the distal end of a probe inserted into a coeliac cavity, and discharge energy sources connected to the first and second electrodes to impress D.C. impulse voltage across them. The apparatus is arranged to disintegrate a calculus by impact waves resulting from spark discharges produced across the first and second electrodes. A polarity changing circuit is provided between the discharge energy sources and first and second electrodes to vary the polarity of the output D.C. impulse voltage from the discharge energy sources.

Abstract: A tape guide mechanism for a tape recorder comprises a pair of first tape guides severally attached to the free end portions of a head lever which has a rotation center in the middle thereof, each of the first tape guides being located on the opposite side of a magnetic head on each side of the head lever to a pinch roller on a pinch roller lever and on the side where its corresponding magnetic head lies. Further, a pair of second tape guides are disposed on the pinch roller lever so as to embrace the pinch roller from both sides thereof, thereby partially covering the pinch roller.

Abstract: An image display apparatus designed so that the field angle for observation can be widened without causing the substrate of an image display device to interfere with the observer's head and without increasing the overall size of the apparatus. The apparatus includes a two-dimensional image display device (6), an optical path splitting device (4), and a concave ocular mirror (5). The image display device (6) is used as an object point of the concave ocular mirror (5), and the object point is projected in the air as an enlarged image for an observer (1) without effecting image formation in the optical path. In the image display apparatus, either or both the optical path splitting device (4) and the concave ocular mirror (5) are decentered so that the display center (7) of the two-dimensional image display device (6) can be shifted away from the observer's head with respect to a reference axis (8) which perpendicularly intersects the observer's visual axis (3) lying when he or she sees forward.
