Patent number: 7322697Abstract: There is provided a method of measuring a pupil distance, which includes locating an imaging device at a position a predetermined distance away from a member attached to eyeglasses worn by a subject. The member has two indicators. The method further includes photographing the subject while the subject observes an observing point in the vicinity of the imaging device, measuring an apparent distance E between left and right pupils on a photographed image, and obtaining an interpupillary distance PD in accordance with PD=[(A+B)×C×E]/(A×D) where “A” represents a distance between the member and the imaging device, “B” represents a distance between a center of rotation and the member, “C” represents an actual distance between the indicators, and “D” represents an apparent distance between the indicators.Type: GrantFiled: September 29, 2004Date of Patent: January 29, 2008Assignee: PENTAX CorporationInventor: Masao Jojiki

Patent number: 6830331Abstract: Magnification viewer includes a conventional glasses and a pair of magnifying lens units. The magnifying lens units are fixed to respective eyeglasses of the conventional glasses so that a wearer of the glasses can observe a magnified image of an object through the magnifying lens units. The magnifying lens unit includes an ocular and an objective lens that constitute a Galilean telescope. A prism is disposed between the ocular and the objective lens for deflecting the optical axis of the magnifying lens unit towards an object placed below the head of a wearer.Type: GrantFiled: October 11, 2002Date of Patent: December 14, 2004Assignees: PENTAX CorporationInventors: Masao Jojiki, Phyo Kim

Patent number: 6398872Abstract: A linear semiconductor material having a thin metal-oxide layer and a resist layer is conveyed at a constant speed by rotating rollers. An electron-beam drawing apparatus, in which micro-electron-guns are aligned circumferentially, is disposed between the rollers. The linear semiconductor material passes through a cylindrical hole of the electron-beam drawing apparatus such that a circuit pattern is formed on a surface of the linear semiconductor material by an electron beam. The linear semiconductor material is developed and etched, and divided into predetermined lengths. Thus a linear semiconductor is completed. A semiconductor device is manufactured by bundling a plurality of the linear semiconductors of predetermined length.Type: GrantFiled: July 1, 1999Date of Patent: June 4, 2002Assignee: Asahi Kogaku Kogyo Kabushiki KaishaInventor: Masao Jojiki
