Patent number: 7145665Abstract: The light emitted from a focal position-detecting light source 38 and reflected from a reflector 12 is projected onto a screen 341, and a projected image on the screen 341 is detected by a focal position-detecting camera 35. Based on this projected image, the focal position-detecting light source 38 is moved by a position adjusting system 37 so as to place the focal position-detecting light source 38 at a focal position of the reflector 12, and the position of the focal position-detecting light source 38 at this time is detected as the focal position of the reflector 12. When the focal position of the reflector 12 is detected, the projected image on the screen 341 detected by the focal position-detecting camera 35 is used, and, therefore, the conventional measurement by a three dimensional measuring instrument is made unnecessary, thereby improving the working efficiency.Type: GrantFiled: January 10, 2002Date of Patent: December 5, 2006Assignee: Seiko Epson CorporationInventors: Yoshiji Iwadare, Kazuto Shinohara, Shohei Fujisawa

Patent number: 6690282Abstract: A light-source lamp unit includes a light-source lamp unit detachably mounted, and a CPU constituting a drive and controller for the light-source lamp unit. The CPU senses lamp information obtained by a lamp-information storing block in the light-source lamp unit, pertaining to a lamp power rating, lamp life and whether a lamp is new or not, and starts counting operation time when the lamp is lit. The CPU compares the lamp life sensed and the operation time count, and forces the lamp to extinguish when the life of the light-source lamp expires. Prior to this action, the CPU gives a warning display before the life expiration of the lamp by a fixed duration of time, to warn that lamp replacement is needed. Because the lamp-information storing block in the light-source lamp unit stores the information about the lamp type and characteristics of the lamp, the light-source device can properly drive the lamp to light it and determine the lamp life even when a light-source lamp unit of a different type is used.Type: GrantFiled: January 31, 2001Date of Patent: February 10, 2004Assignee: Seiko Epson CorporationInventors: Kiyoshi Miyashita, Kazuto Shinohara, Shinji Haba, Akitaka Yajima, Tomiyoshi Ushiyama

Patent number: 6297791Abstract: A display device performs various types of adjustment by canceling luminance dispersion caused by a light source at the time of optical illumination from the light source and correctly sets a gamma correction characteristic even when optical power from the light source varies or is abnormal. In luminance measurement of a display device, an adjustment method includes measuring transmitted light using a sensor and a reference sensor, calculating correction values on the basis of fluctuation values of reference data derived from measured data by the sensor and the reference data by the reference sensor, correcting the measured data, and thereafter converting the data into gradation values.Type: GrantFiled: November 20, 1998Date of Patent: October 2, 2001Assignee: Seiko Epson CorporationInventors: Keijiro Naito, Kazuto Shinohara

Patent number: 6268799Abstract: A light-source lamp unit 100 includes a light-source lamp unit 1 detachably mounted, and CPU 101 constituting drive and control means for the light-source lamp unit. CPU 101 senses the lamp information borne by lamp-information storing block 5 in the light-source lamp unit 1, about a lamp power rating, lamp life and whether a lamp is new or not, and starts counting operation time when the lamp is lit. CPU 101 compares the lamp life sensed and the operation time count, and forces the lamp to extinguish when the life of the light-source lamp expires. Prior to this action, CPU 101 gives a warning display at a time that is earlier than the life expiration of the lamp by a fixed duration of time, to warn that a lamp replacement is needed.Type: GrantFiled: December 10, 1997Date of Patent: July 31, 2001Assignee: Seiko Epson CorporationInventors: Kiyoshi Miyashita, Kazuto Shinohara, Shinji Haba, Akitaka Yajima, Tomiyoshi Ushiyama

Patent number: 6056407Abstract: A liquid crystal panel unit is provided on the light incident face of a prism combining body. The unit has a light valve frame plate for holding a liquid crystal panel and a fixing frame plate fixed onto the light incident face with an adhesive layer. The light valve frame plate is screwed onto the fixing frame plate with a medial frame therebetween. By using wedge members, by adjusting the position of the light valve frame plate on the light incident face, it is possible to precisely position and fix the liquid crystal panel which is held there so that it is possible to control the shifted amount of the pixel alignment and precisely adjust the focus. Thus, it is possible to easily improve the accuracy. Furthermore, the fixing frame plate and the light valve frame plate are composed of materials having linear expansion coefficients ranging from 1/4 to four times that of the prism combining body and from 1/5 to five times that of the fixing frame plate, respectively.Type: GrantFiled: August 12, 1998Date of Patent: May 2, 2000Assignee: Seiko Epson CorporationInventors: Kazuyuki Iinuma, Motoyuki Fujimori, Kazuto Shinohara, Masashi Kitabayashi

Patent number: 6053616Abstract: A liquid crystal panel unit is attached to a light incident surface of a prism composite. The liquid crystal panel unit includes a panel frame plate holding a liquid crystal panel, and a fixation frame plate glued and fixed to the light incident surface. The panel frame plate is fastened to the fixation frame plate by screws through an intermediate frame plate. By using wedges, the position of the panel frame plate with respect to the light incident surface is adjusted. This allows the liquid crystal panel to be reliably positioned and fixed so that the deviation amount in pixel matching is minimized and the focus adjustment can be accomplished correctly.Type: GrantFiled: November 16, 1998Date of Patent: April 25, 2000Assignee: Seiko Epson CorporationInventors: Motoyuki Fujimori, Kazuto Shinohara, Masashi Kitabayashi, Kazuyuki Iinuma

Patent number: 4395507Abstract: The present invention relates to dimedone functional self-bonding room temperature vulcanizable silicone rubber compositions. The self-bond additive is selected from silyl maleates, silyl fumarates, silyl succinates, silyl isocyanurates and mixtures thereof. Preferably the self-bonding additive is prereacted with the cross-linking agent before they are incorporated into the RTV composition. This prereaction of the self-bonding additive and the cross-linking agent imparts shelf-stability to the composition.Type: GrantFiled: December 16, 1981Date of Patent: July 26, 1983Assignee: General Electric SiliconesInventors: John J.
