Patent TW-556179-B (TW)
Title: System and method for aligning components of optical head
Inventor: WILSON SCOTT D
IPC: G11B7/22
Filed: 2001-03-30
Granted: 2003-10-01
Abstract: Extremely small optical heads are being developed for use in optical storage devices. The heads typically include a light source, a lens and a photodetector array. The beam of light generated by the light source must be aligned precisely with central axis of the lens and with the photodetector array. Because the heads are so small, their components are fixed permanently together; no adjustments are possible after assembly. A system of this invention includes a rotational stage, a pair of X-translation stages, and a pair Y-translation stages. The stages are mounted in a mechanical path between first and second holding devices. One component of the head, which would typically include the light source, is held in the first holding device. Another component, which would typically include the lens, is held in the second holding device. The stages are adjusted until the light beam exits the first component on an axis that coincides with the center of rotation of the rotational stage. The position of the second component is adjusted until the light beam coincides with the axis of the lens. The first component is then rotated until the light beam strikes the photodetector array at an optimal position. The optimal position can be obtained by directing light beam at a media driven by a tracking actuator and optimizing the output signal from the head.

Granted: 2003-06-21
Abstract: To prevent a thread from being cut before a moving knife and a fixed knife are mated with each other. A button sewing machine comprising a needle 410, a cloth pressing mechanism 110 for interposing a button and holding a workpiece and a cloth feeding mechanism 150 for moving the cloth pressing mechanism 110 is provided with a thread cutting device 200 according to the invention. The thread cutting device 200 pulls a thread close to a fixed knife 230 through a moving knife 220, and the moving knife 220 and the fixed knife 230 are mated with each other, thereby cutting the thread. Before the moving knife 220 is operated after the sewing is completed, the operation of the cloth feeding mechanism 150 is controlled to adjust the position of the button with respect to the fixed knife 230. Consequently, a distance between a knotted portion and a blade portion 231 is always set to be constant and a length of a residual thread obtained after the cutting is changed optionally.

Title: Memory access method for video decoding
Inventor: JU CHI-CHENG
IPC: H04N1/41
Filed: 2001-05-30
Granted: 2003-03-11
Abstract: A memory access method for video decoding is disclosed. The access method stores a reference picture into memory in macro block size unit. The method groups the data of top field and bottom field of a reference picture within a page and stores each group vertically or horizontally adjacent within a page. When the access method reads only the top field data, since only frame access is needed for each request, the data fetch control is simplified as compared to frame structure buffer memory. On the other hand, a data request for both top and bottom field data can be achieved with less cross page penalties as compared to field structure buffer memory.
