Patent number: 8643947Abstract: There is provided a confocal microscope system configured so as to be compact in size without the needs for a large space, requiring fewer spots for adjustment. In the confocal microscope system, respective units making up the confocal microscope system are integrally housed in a protection cabinet covering the confocal microscope system, and when a specimen disposed opposite to an objective lens is moved toward an external face of the protection cabinet, a side of the external face, adjacent to an opening through which the specimen is taken in, or out, is defined as a front face, the Nipkow disk type scanner unit is disposed backward of the objective lens.Type: GrantFiled: March 2, 2011Date of Patent: February 4, 2014Assignee: Yokogawa Electric CorporationInventors: Taichirou Nezu, Takayuki Kei, Hideo Hirukawa, Yohei Kuwabara, Hironori Takai

Patent number: 7808700Abstract: A confocal microscope system capable of observing a bright field image and a fluorescent image together with a confocal image can be achieved with a simple configuration. The confocal microscope system may include a confocal scanner unit having a microlens array disc and a pin hole array disc, for scanning a face of the observation sample by a plurality of beam spots, a relay lens connected to a camera for acquiring observed images; a microscope for holding the observation sample and illuminating an observation light for observing the bright field image and an excitation light for observing the fluorescent image on the observation sample, and having a port part for outputting the observation light acquired from the observation sample to the confocal scanner unit; and a detour light path unit selectively inserted between the port part of the microscope and the confocal scanner unit.Type: GrantFiled: March 20, 2008Date of Patent: October 5, 2010Assignee: Yokogawa Electric CorporationInventors: Hideo Hirukawa, Mikiharu Kuwata

Patent number: 7346245Abstract: A switch-type imaging fiber apparatus and a branch-type imaging fiber apparatus are provided. Light emitted from a laser light source is made incident on an opening of an IF (image fiber) guided by a GM (galvanometer), output from an optical system provided at a leading end portion of the IF, and applied to an observation target. The light reflected by the observation target is sent back to the IF, transformed into parallel light by an f? objective lens, reflected by a dichroic mirror, made incident on an image pickup device (CCD) via an imaging lens, and can be observed on a monitor. The GM is controlled to switch to make the light incident on the opening of an arbitrary one of a plurality of IFs. Accordingly, observation can be performed by focusing the light solely on the arbitrary IF.Type: GrantFiled: November 16, 2006Date of Patent: March 18, 2008Assignees: National University Corporation, Hamamatsu University School of Medicine, Yokogawa Electric CorporationInventors: Susumu Terakawa, Takashi Sakurai, Yoshihiko Wakazono, Hideo Hirukawa, Takeo Tanaami

Publication number: 20070112248Abstract: A drill unit equipped with a camera, a body of which has a camera hole at the center, and two holes formed to the left and right side of the camera hole 4 including a discharge hole 2 for discharging air and water to the drilled portion, and a suction hole 3 for sucking water and air from the drilled portion. A first and a second drill holes are formed at the top and bottom of the camera hole. Illuminating holes are also formed to illuminate the drilled portion. The camera serves to project an image of the drilled portion. The first and the second drilling members are used to fracture the body tissues, to clean the fractured portion with water, and to suck water used for the cleaning so as to be discharged. The body of the drill unit is rotated to change the drilling position for the fracture in the same way for forming the hole led to the affected portion.Type: ApplicationFiled: November 15, 2006Publication date: May 17, 2007Applicant: Yokogawa Electric CorporationInventors: Susumu Terakawa, Takashi Sakurai, Seiji Yamamoto, Atsuo Miyakawa, Hideo Hirukawa, Takeo Tanaami
