Patent number: 10182929Abstract: A stent delivery system is configured to include an outer tube and an inner tube, with a space between the inner and outer tubes. In the space between the outer tube and the inner tube, a cylindrical mesh reinforcing spacer is provided at a position that is on the base end side of a stent. The reinforcing spacer is provided to be freely movable in the axial direction and radial direction. Even when the outer tube and the inner tube, which have been advanced into the lumen of a living body, are bent, the reinforcing spacer moves in the axial and radial directions and elastically deforms, thereby maintaining a substantially uniform internal circumference for the outer tube along the axial direction.Type: GrantFiled: July 12, 2013Date of Patent: January 22, 2019Assignee: TERUMO KABUSHIKI KAISHAInventor: Masao Yamashita

Publication number: 20100246904Abstract: When a human detection sensor detects a person to be authenticated, an illumination unit obtains ambient light illuminance measured by an illuminance sensor. Lighting illuminance is then determined by using illuminance conversion information, which indicates the lighting illuminance corresponding to the ambient light illuminance, so that when the ambient light illuminance is low, the lighting illuminance becomes low, and when the ambient light illuminance is high, the lighting illuminance becomes high. The illuminance of a light source is controlled so that intensity of illumination becomes the determined illuminance. A face authentication terminal then authenticates the person to be authenticated under illumination by the illumination unit.Type: ApplicationFiled: May 23, 2006Publication date: September 30, 2010Applicant: GLORY, LTD.Inventors: Masao Yamashita, Kazutaka Adachi, Hirofumi Kameyama, Yojiro Kamise, Shunsuke Umaba
