  • Patent number: 7558645
    Abstract: A height sensor 26 and an image recognizing section 28 are installed in a teaching unit 24; the height sensor 26 contacts a pin 30a on a load port 4 to detect the height position of the pin 30a and the image recognizing section 28 recognizes a pin 30c and thus its horizontal plane position. A platform 16 of an overhead travelling carriage 8 grips and lowers the teaching unit 24 toward the load port 4. The height sensor 26 then detects the height of the load port 4. Then, the teaching unit 24 is slightly raised. The horizontal plane position of the pin 30c is recognized and averaged over a time equal to at least the vibration period of the platform 16. As a result, the position of the load port can be accurately taught to the overhead travelling carriage 8 without preparations such as the installation of marks on the load port.

    Abstract: A method of manufacturing a semiconductor storage device includes providing an opening portion in a plurality of positions in an insulating film formed on a silicon substrate, and thereafter forming an amorphous silicon film on the insulating film, in which the opening portions are formed, and in the opening portions. Then, trenches are formed to divide the amorphous silicon film, in the vicinity of a midpoint between adjacent opening portions, into a portion on one opening portion side and a portion on the other opening portion side. Next, the amorphous silicon film, in which the trenches are formed, is annealed and subjected to solid-phase crystallization to form a single crystal with the opening portions used as seeds, and thereby a silicon single-crystal layer is formed. Then, a memory cell array is formed on the silicon single-crystal layer.

  • Patent number: 7464823
    Abstract: A platform 12 is supported by four belts 22 to 25. Of the belts 22 to 25, a pair of belts 24, 25 is attached to a pivoting arm 26 so that the pivoting arm 26 is pivotable around a pivoting shaft 28. Pivoting of the pivoting arm 26 absorbs, for example, the difference in length between the belts 24, 25. The present invention makes it possible to simplify an elevate and lower driving mechanism of the platform 12 and to easily adjust the lengths of the belts 22 to 25. The present invention also makes it possible to prevent vibration during elevation or lowering and to allow the belts 22 to 25 to stand long use.

  • Patent number: 7428201
    Abstract: In the present invention, an optical pick-up (4) applies an optical beam to an optical disc (2) on which one or more information recording layers (20A) and (20B) are laminated in the direction of thickness through an objective lens (34) and detects a reflected light from one of the information recording layers laminated on the optical disc. A first photodetecting part (81) for detecting the reflected light from the one information recording layer and a second photodetecting part (82) composed of one or more light receiving surfaces for detecting a stray light from other information recording layers are mounted on a light receiving element (52). The number of the information recording layers laminated on the optical disc (2) is discriminated on the basis of the intensity of the stray light detected by the second photodetecting part (82). The optical pick-up (4) is controlled in accordance with the discriminated number of the information recording layers before a focus is controlled.
