摘要： A shaft bearing member for supporting a shaft so that the shaft is rotatable has an inner circumferential face serving as a sliding surface. The shaft bearing member includes an oil groove formed in the inner circumferential face so as to circumferentially extend, and a plurality of narrow grooves formed on the inner circumferential face so as to extend at a predetermined angle relative to a rotation direction of the shaft from at least one of both widthwise sides of the oil groove toward an axial end side of the inner circumferential face with respect to the shaft. The narrow grooves guide a lubrication oil from the oil groove toward the axial end side with rotation of the shaft. The narrow grooves are shallower and narrower than the oil groove.

摘要： It is an object of the invention to improve wear resistance and an anti-seizure property of a portion , on which a radial load operates owing to tension of a cogged belt or a V-belt, of a plain bearing for an engine. A main shaft portion of a crankshaft is in uneven contact with an upper half bearing owning to tension of the cogged belt and/or the V-belt. A branch groove is formed in a portion forwarder than an oil groove formed on the bearing surface of a upper half bearing of a plain bearing, the branch groove branching off from the oil groove. When an engine stops, lubricant is stored within the branch grooves, and when the engine restarts, the lubricant within the branch grooves is immediately supplied to the uneven contact portion of the main shaft portion though the rotation thereof.

摘要： A belt drive device is constructed by looping a timing belt 14 about a driving sprocket 9, a cam sprocket 11, and a driven sprocket 12 for transmitting a driving force from the driving sprocket 9 to the sprockets 11, 12. A dynamic damper 15, comprising a ring mass 153 and an elastic ring 152 for holding the ring mass 153, is mounted on the driven sprocket 12 that has the largest amplitde of torque fluctuation among the sprockets 11, 12. The dynamic damper 15 absorbs revolution fluctuations of the driven sprocket 12 that has the largest amplitude of torque fluctuation. Thus, at the time of resonance during which the belt load on the timing belt 15 sharply increases, the sharp increase in the timing belt load can be minimized, and maximum load on the timing belt 15 can be decreased, whereby the durability of the timing belt 15 can be secured.

摘要： A head-mounted image display apparatus having an exit pupil that is enlarged without causing an increase in the size of a relay optical system or a reduction in the size of a projected image. The head-mounted image display apparatus has an image display device (1) having a display surface for displaying an image, a relay optical system (2) for transmitting the image displayed on the display surface of the image display device (1) to form an image of the display surface, and an ocular optical system (4) for projecting the image transmitted by the relay optical system inside an observer's eyeball as an enlarged image. A numerical aperture (NA) enlarging element is disposed at a position conjugated with the display surface with respect to the relay optical system (2). Thus, pupil alignment is facilitated without causing an increase in the size of the relay optical system (2) or a reduction in the size of the projected image. Also, provided as a technique whereby field curvature of the ocular optical system is corrected to provide a flat image for observation.

摘要： A nutrient solution of a microorganism to be supplied to a fermentor or a culture broth in the fermentor is aseptically filtered by a porous filter medium made of polytetrafluoroethylene polymer and having properties impervious to microorganism, resistant to heat and chemicals, and hydrophilic, wherein said hydrophilic property was given to the surface of said filter medium with a treatment for hydrophilicity. This treatment comprises treating polytetrafluoroethylene porous polymer as a raw material for the filter medium with surface treating agent comprising an alkali metal naphthalene and diamine and immersing the treated polymer into concentrated sulfuric acid containing an aliphatic or aromatic aldehyde dissolved therein in a concentration exceeding half saturation.
