  • Patent number: 10352365
    Abstract: A power transmission shaft including a male spline formed in an outer periphery thereof, and a diameter increasing portion formed on a part of a tooth bottom of the male spline, which is located on an opposite side to an axial end of the power transmission shaft. The tooth bottom of the male spline has a substantially constant circumferential width extending up to an axial region of the diameter increasing portion. The diameter increasing portion includes a chamfered portion formed in the axial region of the diameter increasing portion, the chamfered portion connecting the tooth bottom and a tooth flank of the male spline to each other to reduce a tooth groove width.

  • Publication number: 20110257582
    Abstract: An object of the present invention is to safely discard the electrode plate having pin holder-shaped projections of a medicated sheet by incineration. An electrode plate with pin holder-shaped projections is made from a conductive resin in which carbon black serving as a conductive substance is mixed to a thermoplastic resin, so that the electrode plate including the pin holder-shaped projections can be safely discarded by incineration.

  • Publication number: 20090062722
    Abstract: A drug sheet includes a base fabric carrying a therapeutic agent containing an electrolytic drug component and applied to or impregnated into a skin-abutting surface of the base fabric. Small needle members carrying small needle-shaped protrusions are scattered on the skin-abutting surface so that the needle-shaped protrusions protrude from the skin-abutting surface. The needle members include a first group of needle members made of aluminum and provided on a first area of the skin-abutting surface, and a second group of needle members made of silver and provided on a second area of the skin-abutting surface. Due to a difference in standard electrode potential between the first and second groups of needle members, electric current flows between the first and second groups of needle members through skin when the needle-shaped protrusions are stuck in the skin. This improves the absorption rate of the drug component.

  • Patent number: 6659933
    Abstract: A radiation source wire member for radiotherapy indwelling in cancer-affected part of the body comprises an indwelling tip end portion having a radiation source of rhodium coil wire partially converted to 103Pd, and a filament connected to the indwelling portion, the filament having such a length that at least a rear end portion thereof is exposed outside the body after indwelling in the cancer-affected part. An apparatus for delivering the radiation source wire member to the cancer-affected part of the body has a catheter structure comprising (a) an outer tube having an inner diameter permitting the indwelling portion to pass through without resistance, and (b) an inner tube received in the outer tube movably back and forth therein and having an inner diameter not permitting the indwelling portion to pass through but permitting the filament to pass through without resistance.

  • Patent number: 4794260
    Abstract: In one aspect of the invention, the sample surface is wetted with an aqueous solution of a fluorescent dye followed by rinses with water to remove an excessive amount of the dye so that the background fluorescence emission can be minimized to increase the efficiency of fingerprint detection. In another aspect, the fluorescent dye or a reagent to produce fluorescent substance is deposited on the sample surface by attaching a gelatinous film impregnated with a solution thereof followed by peeling. In a further different aspect, a powdery fluorescent dye is deposited on to the sample surface followed by spraying of water to wash away an excessive amount of the powdery dye so that the background fluorescence can be minimized. The invention also provides an apparatus for the fingerprint detection by the laser beam excitation of fluorescence, which is compact and portable as being composed of an ingenious combination of several units into an integral system.

  • Patent number: 4750140
    Abstract: A method and apparatus classifies and grades glossiness based on the visible feeling by the light reflection intensity distribution of a surface of a body, wherein specular reflection intensities and total reflection intensities are detected for two known light fluxes projected at predetermined incident angles. The specular reflection intensities and the total reflection intensities are processed, to thereby determine the glossiness of the work to be measured.

  • Patent number: 4734766
    Abstract: A seam locating system includes a laser beam scanning means for scanning a laser beam through a plurality of circumferentially aligned scanning points. The system includes means for forming a pattern image of reflected laser beam at each scanning points and means for forming a single-frame video image of the pattern image for each scanning point. A video signal processing circuit selects one or more scanning lines suitable for locating irregularities in the angle of reflection of the laser beam, for locating the scanning line in each frame with the maximum width over which the luminosity of the video signal is higher than a given threshold, for deriving a threshold value to be compared with the maximum width of each frame and for deriving the center position of the seam based on the comparison of the maximum width of each frame and the threshold value and the address of each frame, which address is indicative of the circumferential position of the corresponding scanning point.
