Light guide for dental light irradiator

Light guide rod for dental light irradiator

A display apparatus includes a transparent light guide plate, a light source provided on at least one end surface of the light guide plate, and a mask provided on a front surface of the light guide plate. The light guide plate is formed of a plurality of reflecting and scattering portions having reflecting and scattering surfaces that reflect a light emitted from the light source and emit the reflected light from a front surface side. The mask allows an observer to visually recognize the light reflected from a reflective portion for the right eye, using the right eye, and the light reflected from a reflective portion for the left eye, using the left eye, whereby the reflected light beams can be stereoscopically recognized due to binocular parallax.

Display apparatus and lighting window

Disclosed in a door mirror device capable of continuously emitting light from two light guides. The door mirror device comprises: a first light-emitting light guide arranged in the visor part of a door mirror foldably mounted on the door mirror support part of a vehicle; a second light-emitting light guide provided in the door mirror support part, an end of the second light-emitting light guide facing to an end of the first light-emitting light guide so as to have continuity with the first light-emitting light guide; and a light source configured to emit light toward the first light-emitting light guide and the second light-emitting light guide, the light source being provided in the visor part.

Door mirror device for a vehicle

The present invention relates to a manufacturing method of a display apparatus having a display portion that is made of dot-like reflection portions. The method comprising steps of: heating at least one of a blade portion of a machining tool and a light guide plate, descending the machining tool along a specific formation direction of the blade portion all through this descending step to press the blade portion into a back surface of the light guide plate, ascending the machining tool along a specific formation direction of the blade portion all through this ascending step to pull out the blade portion from the light guide plate, moving the machining tool horizontally, and arranging at least one light source along at least one edge face of the light guide plate. The steps of descending, ascending, and horizontally moving the machining tool are performed repeatedly to form the dot-like reflection portions.

The invention relates to nanostructure and its manufacturing method. In the manufacturing method of a nanostructure, first anisotropic crystalline particles, connectors having end to be connected to a specific crystal face of each of said crystalline particles, and second particles to be connected to the other end of each of said connectors are prepared. First ends of the connectors are connected to specific crystal faces of the first crystalline particles, and simultaneously or before or after the connection, the second ends of the connectors are connected to the second particles. A nanostructure formed by this method has a three-dimensional structure which does not have a closest packing structure.

The illumination device is provided with a plurality of light guide bodies, the bottom face of which is given light reflection/scattering treatment, light sources individually connected to the end portions of a plurality of the light guide bodies to radiate the bottom faces of a plurality of the light guide bodies, and a control unit for changing the intensity of light made incident from the light sources to a plurality of the light guide bodies. A plurality of the light guide bodies are laminated so as to be at least partially overlapped at the respective light emitting regions of the light guide bodies, and the control unit allows the intensity of light made incident from the light sources to the light guide bodies to change with the lapse of time.

Illumination device having light guide body

A scuff plate of the invention is a scuff plate which has a luminous unit of which a side surface of side surfaces forms a luminous surface, a light source unit which emits light to the luminous unit, and a light guiding unit which is disposed in such a manner that a side surface thereof faces the luminous surface, wherein the light guiding unit has a luminous surface portion which expands in an intersecting direction relative to a front surface thereof. The scuff plate of the invention provides a scuff plate which has superior design properties without increasing the thickness of the whole thereof.
