Abstract:
An abutment plate assembly for a cutting machine includes an abutment plate unit, an extension plate unit, and a locking unit. The abutment plate unit includes a sliding rail unit having a generally T-shaped cross section. The extension plate unit is formed with a slide slot having a generally T-shaped cross section and engaging the sliding rail. The locking unit includes a pressing member movable vertically within the slide slot, a resilient member for biasing the pressing member to move away from the abutment plate unit, and a rotary lever unit. The rotary lever unit is rotatable so as to move the pressing member toward the abutment plate unit until the pressing member presses the extension plate against the abutment plate unit to thereby lock the extension plate unit on the abutment plate unit.
Abstract:
An optical disk drive includes a disk-carrying tray, a shielding member and buffer member disposed at adjoining position of the disk-carrying tray and the shielding member to absorb impact of broken pieces in case of breakup of an optical disk during the reading and writing operations.
Abstract:
A device (2) for inspecting a matrix substrate (26) includes a light source (22), an electro-optical device (20) determining whether light beams penetrate through or not, a photodetector (23) positioned at one side of the electro-optical device and a host computer (24) connected with the photodetector. A matrix substrate is positioned between the electro-optical device and the light source. The device is used to receive image data, and then the image data is compared with the predefined data to determine whether defects on the matrix substrate exist. Efficiency of inspection can be significantly improved. A related method is also provided.
