  • Patent number: 7889331
    Abstract: A bidirectional optical module according to the present invention comprises light emitting elements 110, 130 that emit light to enter an optical fiber 71, a light receiving element 190 that receives light having exited the optical fiber 71 and a light branching element 160 that guides the light having exited the optical fiber 71 onto the light receiving element 190. It further includes a stray light shielding member 185 disposed between the light branching element 160 and the light receiving element 190 and having formed therein an opening 186, through which the light to enter the light receiving element 190 passes. The stray light shielding member 185 blocks stray light 100b while light 100a having exited the fiber 71 passes through the opening 186. Therefore, any increase in the extent of error in the detection of the returning light level or the position of a reflecting point is prevented.

  • Patent number: 6770808
    Abstract: A thermoelectric module includes plural thermoelectric semiconductor chips connected in series, first and second substrates, plural first and second electrodes formed on the first and second substrates, first solder through which the first and second electrodes are bonded to end portions of the thermoelectric semiconductor chips. The first substrate includes two or more protrusions protruding toward opposite sides with respect to the second substrate when being viewed vertically. A method of assembling a thermoelectric module in a radiating member includes the steps of mounting the first substrate on a radiating member through the second solder having a liquidus temperature lower than a solidus temperature of the first solder; holding the protrusions by leading edges of support arms where the second solder is melted to push the first substrate toward the radiating member under pressure while rocking the first substrate in a direction orthogonal to the pushing direction.

  • Patent number: 5050231
    Abstract: A relief image scanner scans successive linear areas on an information-carrying medium such as a plastic card, illuminating each area from two different directions. The reflected light is converted to first gray-level data when the illumination is from one direction, and to second gray-level data when the illumination is from the other direction. The second gray-level data are subtracted from the first gray-level data; then the difference, and its additive inverse, are compared with a threshold to detect edges of relief patterns on the card, and pairs of edges are connected to create an accurate, distortion-free image of the relief. Additional facilities may be provided to extract edge skeletons before joining the edges, and to capture printed information by binarizing the gray-level data.

  • Patent number: 4672219
    Abstract: An image reader is adapted to read an image represented on a document. The image reader comprises a reading unit, an LEDs driving circuit, and means for moving the reading unit and the document relatively. The above reading unit comprises an LEDs array arranged in a straight line as light sources, a rod lens array for guiding the light emitted from each LED of the LEDs array and focusing the light on the document, and a pair of photosensors being disposed in parallel and connected in parallel with respect to each other for converting a reflected light from the document to a photocurrent. And each LED of the LEDs array is turned on only one at a time sequentially by means of the LEDs driving circuit, then the reading of the document is effected by means of the photosensors.
