The present invention provides an optical bridge for interconnecting optical networking components and methods of making optical bridges that include a waveguide that are compatible with semiconductor processing steps. The optical bridge of the present invention has less optical losses and is less affected by misalignment that prior art interconnections. The waveguide is formed of a curable optical material that spans optically active areas of two components. In one embodiment of the present invention, one optical component is an optical circuit board and the connected optical component is an electro-optical integrated circuit package containing light emitting or light receiving elements. The method provides a curable optical liquid to the components, bringing the components together to form a continuous optical liquid between the components, and curing the optical liquid.

An image reading apparatus includes a line light source having a light guide plate and red-, green-, and blue-LEDs, for a light transmitting original, and a contact image sensor unit for detecting light from the line light source. The light transmitting original is arranged between the line light source and the contact image sensor unit. The light transmitting original is read by moving the line light source and the contact image sensor unit relative to the light transmitting original. The line light source is moved interlockingly with the contact image sensor unit by the attraction between a magnet provided at both ends of the line light source in the longitudinal direction thereof and a magnet provided at both ends of the contact image sensor unit in the longitudinal direction thereof.

A light-guide device has a single piece body including a plurality of light guiding elements joined together by at least one supporting element. An opaque coating is provided on an outer surface of the at least one supporting element, to absorb the light entering into the supporting element from the light-guide elements.

A diaphragm comprising a single plate, the single plate comprising: a first plate portion having an aperture; and a second plate portion formed at an outer side of the first plate portion, wherein a first thickness of the first plate portion is thinner than a second thickness of the second plate portion.

An input function display device includes: a position information reading unit that is provided with an imaging element optically reading a position information pattern representing a coordinate position on a plane; and a display unit that performs display on the basis of marks read from the position information pattern recorded in a display area, wherein the display unit includes a transparent conductive film having a conductive pattern in which the position information pattern is applied onto the transparent substrate, and a display portion that performs display using the conductive pattern as a common electrode.

The invention discloses a trackless auto-clean high-airtightness sliding door / window, comprising a door / window frame and a door leaf / window sash; tracks on a lower frame member of the door / window frame include front and rear concave flat tracks formed among front, middle and rear vertical frame bars on the flat bottom of the lower frame member; the door leaf / window sash is disposed in the door / window frame correspondingly between the upper and lower frame members, and the door leaf / window sash is slidably moved in the corresponding concave flat tracks of the lower frame member through a multifunctional integrated roller mechanism at the bottom; in the multifunctional integrated roller mechanism, horizontal lateral guide wheels in rolling contact with the lateral sides of the concave flat tracks are arranged in left and right bodies of roller carriers, a rolling wheel in rolling contact with the bottom of the corresponding concave flat track is arranged in the roller carrier between the left and right horizontal lateral guide wheels, and the left and right ends of the roller carrier are provided with plastic sheets or rubber sheets or flexible brushes abutted to the bottoms of the concave flat tracks. The trackless auto-clean high-airtightness sliding door / window can provide effective prevention of separation, has good safety, allows water and dust in the concave flat tracks t be cleaned in time, and is airtight and opaque.
