    摘要: A quick coupler for mounting a rotational disk which enables the rotational disk to be quick connect to or disconnect from a pad conditioner disk holder is disclosed. The quick coupler consists of two major components of a disk holder and a travel housing. The disk holder is formed in a ring shape having a center aperture in a polygon shape for intimately engaging a polygon-shaped shaft of the travel housing such that a rotational torque can be transmitted from the travel housing to the disk holder. Each side of the polygon is provided with a steel ball and a recessed slot behind the ball for receiving a jutting key operated by a retractable ring attached to the travel housing. The travel housing is formed in a cylindrical shape that has a first end threaded for engaging a drive means and a second end in the polygon shape.

    摘要: A high-speed bus interface with an adaptive swing driver. A high speed interface includes a transmitter and a receiver coupled via a bus. The transmitter has an adaptive swing driver and a voltage-regulating-module (VRM). The adaptive swing driver includes a post-driver and a pre-driver. The post-driver provides an adaptive swing output with a dedicated adaptive voltage power supply (VDDQ) and transition emphasis driving capacity with an internal logic voltage supply (VDD). The pre-driver provides the transition emphasis driving capacity with a pull-up and a pull-down signal path to the post-driver. The voltage-regulating-module is configured to supply signal to the adaptive swing driver. The receiver includes a comparator and a bit-error-rate detector. The comparator amplifies the adaptive swing output received from the transmitter via a bus, while the bit-error-rate detector diagnoses the amplified adaptive swing output received from the comparator.

    摘要: A synthesis subband filter apparatus is provided. The apparatus is used for processing 18 sets of signals which each includes 32 subband sampling signals in accordance with a specification providing 512 window coefficients. The apparatus includes a processor for processing the 18 sets of signals in sequence. The processor further includes a converting module and a generating module. The converting module is used for converting the 32 subband sampling signals of the set of signals being processed into 32 converted vectors by use of 32-points discrete cosine transform (DCT), and writing the 32 converted vectors into 512 default vectors with a first-in, first-out queue. The generating module is used for generating 32 pulse code modulation (PCM) signals, relative to the set of signals being processed according to a set of synthesis formulae proposed in this invention.
