Abstract:
An optical sensor for use in high vacuum plants and/or in ultrahigh vacuum plants has a metal housing surrounding an interior space in a manner substantially impermeable to gas in which a window which transmits light to be detected is provided and an optical sensor element arranged in the interior space for the detection of light to be detected which is incident through the window.
Abstract:
A storage information system is disclosed for keeping archival information on the individual active optoelectronic components that are used in telecommunication equipment. The system involves enclosing a nonvolatile memory chip inside the hermetic package of the active optoelectronic component. A memory chip is used to keep the relevant information about the active optoelectronic component such as serial number, part number and specifications. Sensors can also be included inside the hermetic package to monitor the operating conditions of the optoelectronic component. The information system is capable of storing information that is relevant to the component reliability such as: hours of operation, maximum current or voltage, and maximum temperature. The information storage system has the advantage that the archived information is intimately associated with the optoelectronic component thereby lessening the likelihood that information is lost or tampered with. The information system eliminates need for keeping paper records on individual optoelectronic components. It also provides a means for determining if the optoelectronic component was operated outside its specified operating limits. The users of optoelectronic components can also access the information system as needed for the purposes of repair or maintenance of telecommunications equipment.
Abstract:
A light-blocking structure on an optical lens mounting device for an optical scanning module. A circular flange is formed inside an engaging tube adjacent to one end of the optical lens for blocking any diffused light passing through the gap between the optical lens and the engaging tube so that an associated optical sensor may obtain a clearer image.
Abstract:
A coating start point is altered to avoid flowing of a sealing resin to an EL element when the sealing resin is pressed and flattened on adhesion of a device substrate and a sealing substrate with the sealing resin interposed therebetween. In a manufacturing method of a display device of the invention which is formed by adhering the device substrate and the sealing substrate with the sealing resin interposed therebetween, when the sealing resin is coated along edges of the device substrate and the sealing substrate, the coating is started on a corner of the substrates as a coating start point and a coating end point is on the same corner as for the coating start point.
Abstract:
One or more mounting registration points provide alignment between a FIMS system and a specimen handling system that delivers a specimen retrieved from a specimen transport box. The specimen handling system includes one or more mounting points, each cooperating with an alignment fixture to immovably secure the specimen handling system to the FIMS system at a corresponding mounting registration point. This mounting technique provides automatic alignment of the specimen handling system to each mounting registration point of the FIMS system.
Abstract:
An optical communication device having features such as: a simple structure, easily mountable, less restrictions in arrangement designing, easy to attain compact arrangement, a mechanical sturdiness and a stable wide directional angle, is constituted as follows. A plurality of LED lamps as photo-emitting elements are mounted on a base plane with a predetermined angle inclined around long axe of the respective LED lamps and the long axe of the LED lamps are arranged so as to dived a circle on the base plane equally.
Abstract:
A photonic package includes a housing having a semiconductor light source disposed within the housing. The semiconductor light source has a first output and a second output. A reflective surface is disposed inside the housing to reflect the second output from the semiconductor light source. A photodetector is also disposed within the housing and is adapted to indirectly receive the second output of the semiconductor light source reflected off the reflective surface. As a result, interior surface of a housing of an optical transponder may be utilized to provide reflected light to a photodetector to monitor the semiconductor light source.

Abstract:
A structure of a photosensor for receiving optical signals and converting the optical signals into electrical signals to be transmitted to a circuit board, the structure of the photosensor includes a substrate, a photosensitive chip, and a transparent layer. The substrate has a first surface formed with signal input terminals, and a second surface opposite to the first surface and formed with signal output terminals for electrically connecting the substrate to the circuit board. The photosensitive chip is mounted on the first surface of the substrate and electrically connecting to the substrate. The transparent layer is adhered onto the first surface of the substrate. A cavity is formed at a central portion of the transparent layer. The photosensitive chip on the substrate is located within the cavity of the transparent layer, and the photosensitive chip is capable of receiving the optical signals via the transparent layer. According to this structure of the photosensor, the optical signals can be received more effectively, the quantity of the material can be save, and thus, the manufacturing costs can also be lowered. A method for packaging the photosensor is also disclosed.
