  • Patent number: 9919139
    Abstract: With the present invention the sheet shaped therapeutic substance can be accurately and easily affixed to the inside of the human body. As shown in FIG. 6A, the sheet shaped substance can be mounted on the head with wrinkles being formed. When this takes place, the sheet shaped substance is held in contact with the outer periphery of the head. Then, by making the pressure of the fluid inside the vent apertures positive, the sheet shaped substance can be blown off. The surface of the head is closely parallel to an inner surface of the esophagus wall for the sheet shaped substance to be affixed. Therefore, this particularly makes it possible to perform such applying step (FIG. 6B) in a more reliable fashion.

  • Publication number: 20100055530
    Abstract: Each of collectors 22 of an electrode structure 20, which partially constitutes a polymer electrolyte fuel cell, is formed from a metal lath MR having a large number of through-holes. A stopping portion 22a in which the through-holes are reduced in diameter is formed at a peripheral end portion of the collector 22. The peripheral end portion of the collector 22 is folded; subsequently, the folded peripheral end portion is pressed, thereby forming the stopping portion 22a. A resin seal portion 23 for sealing introduced fuel gas and oxidizer gas is formed integrally with the stopping portions 22a by insert molding which is performed such that an injected molten resin encloses the stopping portions 22a. The resin seal portion 23 formed integrally with the stopping portions 22a can reliably prevent inflow of the molten resin toward central portions of the collectors 22.

  • Patent number: 6157478
    Abstract: In a multibeam scanning optical apparatus of a type where two parallel lines are simultaneously scanned by two laser beams irradiated from two semiconductor lasers, stable images are formed on the scanned surface by the two laser beams and the cost is reduced. The two laser beams irradiated from the two semiconductor lasers are directed substantially in the same direction through a beam splitter and then shaped by a condenser lens into two luminous fluxes whose optical axes are substantially parallel to each other. In another arrangement, the semiconductor lasers are directly secured to a surface of the beam splitter by use of an ultraviolet setting resin.

  • Patent number: 6118570
    Abstract: A laser beam scanning optical apparatus has a focusing lens having different optical powers in the main scanning direction and the sub-scanning direction, moving means for moving the focusing lens on an optical direction, detecting means for detecting a state of convergence of the laser beam on a scanned surface, and control means for adjusting the convergence position of the laser beam by moving the focusing lens via driving said moving means based on the detection result of the detection means. In the aforementioned construction, the state of the convergence of the laser beam on a scanned surface is adjusted in the main scanning direction and the sub-scan direction by moving the focusing lens in an optical axis. The focusing lens is moved to a position of optimum convergence based on the construction of the optical system by detecting the state of convergence in the main scan direction and the sub-scan direction via a detecting means.

  • Patent number: 6097421
    Abstract: In a scanning optical system in which image-surface curvature in the traverse direction is corrected properly without degrading imaging performance in the scanning direction and in which the transverse magnification is approximately uniform irrespective of the deflection angle, the influence of form errors in the imaging lens upon the image is substantially suppressed so as not to degrade the quality of the image. The scanning optical system is provided with a aspherical lens having a refractive power only in the traverse direction and having a TSL shape whose curvature radius increases as the distance in the scanning direction from the center of the lens (the position in which the curvature radius in the traverse direction is smallest) increases. The aspherical lens is disposed in such a way that the line of symmetry that passes through its center is parallel to and at a distance from the optical axis of a first lens unit on the upstream side of a scanning path in the scanning direction.

  • Patent number: 6072176
    Abstract: A laser beam optical scanning device which focuses and scans a laser beam emitted from laser diode 1 in the arrow b direction on a photosensitive drum 40 via focusing lens 3, polygonal mirror 6, and f.theta. lens 7. The scanning laser beam enters a convergence state detector 10, which detects the amount of dislocation of the convergence position. The amount of positional change is calculated to correct the convergence position based on the detected amount of dislocation, and the focusing lens 3 is moved on the optical axis of the lens via motor 21 to correct the beam convergence position. When processing is executed to correct the convergence position in the intermediate zone of the image formign range and the calculated amount of positional change exceeds a limit value, a detection error is assumed, and the focusing lens 3 is moved an amount less than the limit value.

  • Patent number: 5969346
    Abstract: A laser beam scanning optical apparatus which images and scans a laser beam emitted from a laser diode on a photo-sensitive drum through a focusing lens, a polygon mirror and an f.theta. lens. An SOS photosensor detects the scanned laser beam and generates a detection signal. The laser diode is controlled to perform pulse emission a specified time after the generation of the detection signal. The pulse beam is incident to a beam detector which adopts a knife edge method, and the amount of a focal shift is detected. The focusing lens is moved along the optical axis in accordance with the detected amount of a focal shift to correct the position of the image point.
