Abstract: The present invention provides an optical disc including a substrate. The substrate has a label surface. According to the invention, an ink mixture, including a plurality of functional microcapsules, is coated on the label surface to form a coloring layer. In an embodiment, at least part of the functional microcapsules encapsulates an ultraviolet light absorbent to increase the light fastness of the coloring layer.

Abstract: A tensioning assembly for a polishing belt on a linear chemical mechanical polishing apparatus. The tensioning assembly comprises first and second rollers which are operably engaged by respective air cylinders and exert a selected degree of downward tension on the lower run of the horizontal polishing belt. A third roller biased typically by a spring pushes upwardly on the lower run of the belt between the first and second rollers. Accordingly, the first and second rollers, in conjunction with the third roller, tension the belt on the apparatus to maintain optimum material removal rates and uniformity. The degree of tension exerted on the belt can be varied according to stretching of the belt resulting from prolonged use.

Abstract: A system and method for interfacing peripheral devices to a computer universal serial bus is disclosed. The system is adaptable to a wide variety of peripheral devices and features a user-configurable serial EEPROM coupled to the interface in which vendor specific data can be stored for use by the interface. Interface parameters may also be selected by an externally controllable configuration switch.
