20080218109 | Aperture driving apparatus and projection type image display apparatus - An aperture driving apparatus includes a swing unit and a stationary unit. The swing unit includes an aperture plate that partially blocks a light, a coil that constitute a voice coil motor for obtaining a driving force for driving the aperture driving plate, and a swing arm that supports the aperture plate and the coil and has a bearing portion between the aperture plate and the coil. The stationary unit includes a swing shaft that engages the bearing portion and swingably supports the swing arm about a swing axis, and a magnet and a yoke that constitute the voice coil motor together with the coil. A control unit of the aperture driving apparatus controls the swing angle of the swing arm using a closed-loop control technique. In the direction of the swing axis, the position of a center of gravity of the swing unit is substantially aligned with a position at which the driving force is applied to the coil. | 09-11-2008 |
20080252861 | Rear projection type display apparatus - A rear projection type display apparatus includes a base in which an optical unit and an electrical circuit are accommodated and which has an opening at a rear side thereof, and a cabinet which supports a mirror and a screen and which is mounted to an upper side of the base. The base has a first connecting portion provided along at least one side of the opening, and the cabinet has a second connecting portion which engages the first connecting portion of the base along at least one side of the opening. One of the first connecting portion and the second connecting portion has a cross sectional shape which includes two facing inner walls and which is opened in one direction. | 10-16-2008 |
20080252968 | Projection-type image display apparatus - A Fresnel lens collimates a light modulated by an image signal and outputs a collimated light. A diffusion member diffuses the collimated light and outputs a diffused light. A driver continually moves the Fresnel lens or the diffusion member on a predetermined trajectory within a plane parallel with a screen. A spring member couples the Fresnel lens or the diffusion member with a casing, including a first deformation plane flexible in a first direction within the plane, and a second deformation plane flexible in a second direction substantially perpendicular to the first direction within the plane, while it is not flexible in a direction perpendicular to the plane. | 10-16-2008 |
20090097164 | Drive with voice coil motor - A drive is provided executing high-speed oscillatory motion. A voice coil motor in a pixel shifter includes a coil of a rectangular shape producing thrust along an axis, a flap fixing the coil, and flat springs giving to the flap an urging force against the thrust. An oscillation axis of the flap is parallel to the axis and located between another axis that is parallel and opposite to the axis and still another axis that is parallel to the axis and passes over a centroid of the coil. This reduces the value of the inertia per unit torque. | 04-16-2009 |
20090109530 | Projection-Type image display device - In a projection-type image display device, a driven member of a screen is displaced in a plane parallel to the screen. The driven member can be a Fresnel lens or a diffusing member. An elastic retaining unit holds the driven member in such a manner as to be capable of moving in the plane parallel to the screen, and a pair of driving sources applies driving forces in mutually intersecting directions to the driven member. A control circuit drives the pair of driving sources with driving waveforms having a prescribed phase difference therebetween so that the driven member makes continuous motion in a plane parallel to the screen when an image is projected. | 04-30-2009 |
20090184775 | OSCILLATION DRIVE DEVICE - An oscillation drive device includes an oscillating unit that includes attaching portions on either sides thereof, the attaching portions being arranged on an oscillation axis; a base that includes an oscillating fulcrum that supports the oscillating unit on the oscillation axis and supporting portions that firmly support the oscillating unit; and a pair of strip-shaped leaf springs that is arranged so as to intersect with the oscillation axis and oscillates the oscillating unit on the oscillation axis, each of the strip-shaped leaf springs includes a fixing portion attached to the attaching portions of the oscillating unit; and a flexible beam portion that both ends of which are attached to the supporting portions of the base, and causes the oscillating unit to oscillate on the base by flexure behavior thereof. | 07-23-2009 |
20100020395 | PROJECTION TYPE IMAGE DISPLAY APPARATUS - A projection type image display apparatus includes an optical engine that emits a light according to image signal, a Fresnel lens on which the light emitted by the optical engine is incident and emitting the light as a parallel light, and a diffusion member that diffuses the parallel light emitted by the Fresnel lens. The projection type image display apparatus further includes a driving unit that moves the Fresnel lens or the diffusion member in a plane parallel to an emitting surface of the Fresnel lens or the diffusion member, a frame the supports the Fresnel lens, the diffusion member and the driving unit, a resilient supporting body that supports a weight of the Fresnel lens or the diffusion member with respect to the frame, and a holding unit that holds the Fresnel lens or the diffusion member so as to be movable in the plane parallel to the emitting surface of the Fresnel lens or the diffusion member. | 01-28-2010 |
20100328622 | PROJECTION DISPLAY APPARATUS - A projection image display apparatus is provided which is capable of preventing misregistration in an on-screen image. A main frame assembly holds together an optical engine that modulates light emitted from a light source and a screen on which light emitted from the optical engine is projected, and the main frame assembly is configured to be supported by a bottom frame formed by a separate structure, whereby distortion having occurred at the bottom frame is caused not to transmit to the main frame assembly. | 12-30-2010 |
20110116057 | REFLECTOR MOUNTING STRUCTURE AND PROJECTION DISPLAY DEVICE - A reflector mounting structure includes a reflector and a fixing member. The reflector includes: a reflecting surface; a reflector body having the reflecting surface formed thereon; a pair of first connecting units provided respectively at an end face of the reflector body and having a substantially spherical first protrusion at an end thereof; and a second connecting unit provided at an end face of the reflector body. The fixing member which supports the reflector includes a pair of first supporting units respectively having a planar contact portion and bringing the contact portion into contact with an end of the first protrusion, and a second supporting unit. | 05-19-2011 |

20140014165 | SOLAR BATTERY SYSTEM AND SOLAR BATTERY MODULE - Each of solar battery modules includes a rectangular solar battery panel, and a holding member extending from an inner side of the solar battery panel to opposite short sides thereof in a direction parallel to a long side of the solar battery panel. A mount includes rod-like members, to which a row of short-side groups in which sets of short sides of the solar battery panels adjacent to each other are arranged in a direction along the short sides is fitted via the holding members. The holding members are bonded to a rear surface of the solar battery panel. The long side is equal to or longer than 1.3 meters, and the short side is equal to or longer than 0.9 meter. The solar battery panel includes a glass substrate having a total plate thickness of equal to or smaller than 2.5 millimeters. | 01-16-2014 |
20150068589 | REINFORCING FRAME AND SOLAR BATTERY MODULE - To obtain a reinforcing frame capable of securing sufficient reinforcing strength and adhesive strength while suppressing a manufacturing cost by omitting a rim-like frame.
