20090072695 | IMAGE DISPLAY DEVICE - This is to provide an image display device using a spacer | 03-19-2009 |
20090280712 | METHOD OF MANUFACTURING SUPPORT MEMBER - A method of high precisely manufacturing, for an electron beam displaying apparatus, a support member which is equipped with an electrode on the surface thereof is provided. In this method, an electrode region is formed on the surface of a base material, the surface of the base material is ground by using a grinding stone having a convex portion, and at the same time a fringe portion of the electrode region is ground to form an electrode. | 11-12-2009 |
20110019345 | IMAGE DISPLAY APPARATUS | 01-27-2011 |
20110050078 | IMAGE DISPLAY APPARATUS - An image display apparatus according to the present invention comprises a rear plate having electron emitting devices, a face plate having an anode electrode arranged in opposition to the electron emitting devices, and a plate-shaped spacer arranged between the rear plate and the face plate, wherein the spacer has a recess at its side of the face plate, the anode electrode has an edge located in opposition to the recess, the recess has the shape of a circular arc having a radius r, and when it is assumed that the recess has a maximum depth of d, a relation of r/d≧1 is satisfied. | 03-03-2011 |
20110050079 | DISPLAY APPARATUS - A display apparatus comprises: a rear plate which has an electron-emitting device; a face plate which has an anode electrode and a potential defining electrode; and a plate spacer which is opposite to the anode electrode and the potential defining electrode, between the rear plate and the face plate. An insulative base member of the spacer has a recessed portion which opposes to the anode electrode, the potential defining electrode, and a portion of the face plate between the anode electrode and the potential defining electrode. Thus, electric discharges between the spacer and the anode electrode and between the spacer and the potential defining electrode can be suppressed. | 03-03-2011 |
20120080997 | IMAGE DISPLAY APPARATUS - A spacer positioned between a faceplate and a rear plate so as to extend across a first region on which an anode is provided and into a second region on which the anode is not provided is included. The spacer includes a plurality of conductive members extending across a first section of a side surface of the spacer that underlies the first region and into a second section of the side surface of the spacer that underlies the second region, distances from the faceplate to the conductive members differing from each other. The plurality of conductive members have an end portion in the second section. The position of the end portion of a conductive member farther from the faceplate is farther from the end portion of the anode. | 04-05-2012 |

20130321602 | ENDOSCOPE AND ENDOSCOPE SYSTEM - An endoscope has an illuminating-light exit portion that allows illuminating light for illuminating an object to exit, and an observing portion that captures an image of the object. The endoscope includes a changing unit configured to change a light quantity distribution of the illuminating light. The changing unit changes the light quantity distribution of the illuminating light based on information of the image captured by the observing portion. | 12-05-2013 |
20140088353 | STEREO ENDOSCOPE APPARATUS AND IMAGE PROCESSING METHOD IN STEREO ENDOSCOPE APPARATUS - The stereo endoscope apparatus includes: a treatment instrument that is operable; multiple imaging units for imaging a subject, the multiple imaging units acquiring, in response to an operation of the treatment instrument, an image in which the treatment instrument does not appear and an image in which the treatment instrument appears; a detecting section for detecting the area of the image where the treatment instrument appears; an area determining section for determining a replacement area in which an image is to be replaced, the replacement area being at least a part of the area in which the treatment instrument appears; and an image processing section for replacing the replacement area by the image in which the treatment instrument does not appear. | 03-27-2014 |
20140092215 | ENDOSCOPIC SYSTEM - In a stereoscopic endoscope apparatus, images obtained by left-eye and right-eye imaging systems are shaded differently due to subtle difference in an illumination direction, making fusion difficult. An endoscopic system includes: a stereoscopic endoscope which includes a light source of illumination light configured to illuminate inner part of a test object, an illumination window configured to emit the illumination light, and two or more imaging systems configured to image the inner part of the test object illuminated by the illumination light; and an illuminance distribution changing unit configured to change an illuminance distribution of the illumination light so as to reduce a difference in luminance distribution between/among pictures sensed by the respective imaging systems. | 04-03-2014 |
