Title: Digitally controlled oscillator circuit of digital phase lock loop
Inventor: PAN JIAN-DAI
IPC: H03L7/089
Filed: 1999-06-29
Granted: 2001-08-21
Abstract: The present invention discloses a digitally controlled oscillator (DCO) circuit of digital phase lock loop (DPLL) in which the fractional frequency-division architecture will generate the required destination time sequence to compare with the output time sequence before using the phase/frequency comparison results to drive a counter loop filter for counting. If the count of the counter loop filter reaches a preset value due to a significant phase/frequency difference between the destination time sequence and the reference time sequence, a control logic circuit will be driven to adjust a multi-bit serial-connected latch so that the output time sequence can appropriately be adjusted to meet the requirements of the destination time sequence. Besides, signals coming from the all-digital loop filter can be filled into the fractional frequency-division architecture to vary the frequency of the destination time sequence. Hence, without having to furnish with any extra circuit architecture, the frequency of the destination time sequence may be varied and adjusted in accordance with the external factors to meet the requirements.

Granted: 2004-09-11
Abstract: An electrically functional adhesive transfer for use in the manufacture and/or the design of flexible membrane circuits. Electrical circuit elements, instead of being printed directly upon polyester film substrates, are printed upon a carrier sheet. A pressure sensitive adhesive is applied over the exposed surfaces of the printed circuit pattern on the carrier sheet and covered by a release paper. The circuit later is applied to any desired substrate by peeling away the release paper and mounting the circuit by means of the pressure sensitive adhesive. The carrier sheet typically is peeled away after the circuit is adhesively bonded to the substrate. The carrier sheet desirably is transparent or translucent in order to facilitate visual alignment of the circuit pattern with the substrate to which it is being bonded.

Title: Manufacturing method and structure of the shadow mask of color cathode ray tube
Inventor: TZENG CHING-SHIANG
IPC: H01J29/07
Filed: 1999-10-19
Granted: 2001-05-01
Abstract: The present invention relates to manufacturing method and structure of the shadow mask of color cathode ray tube. A plurality of focusing holes are installed in equally spaced or about equally-spaced arrangement on the shadow plate of a color CRT, wherein the focusing hole located at the center of the shadow plate is circular and the other focusing holes are designed to be elliptical along the radial direction. The long axis of the elliptical focusing hole is perpendicular to the lengthened direction by the pulling force during mechanical formation of the shadow mask to compensate for the expansion/contraction effect of the focusing hole of the shadow mask after mechanical-spherical formation. The elliptical focusing holes become circular holes after they are spherically formed, so that the shape of focusing hole makes the shadow mask become a good exposure photomask in the color CRT process for coating the inside of the phosphor screen to ensure that the phosphor deposit inside the display screen can be coated to the corresponding position accurately to promote the coating quality of the phosphorus screen.

Title: Method for joining wafers at a low temperature and low stress
Inventor: LO YU-HWA
IPC: H01L21/18
Filed: 2000-07-15
Granted: 2001-12-21
Abstract: The method of the present invention is used to join two dissimilar materials together, and particularly to transfer a film to a substrate when the difference in thermal expansion coefficients between the film and the substrate is very big. A hydrophilic surface is created on one material and an atmosphere reactive metal element is deposited on the surface of another material. When the materials are tightly contacted, with the reactive element pressed against the hydrophilic surface, the reactive metal element reacts with the moisture from the hydrophilic surface at room temperature. Strong bonds form during the reaction joining the two materials together. Because the procedure takes place at room temperature, extremely low stress is built in. the film joining is successful even with a big thermal expansion coefficient difference between the materials, such as exist between GaAs and silicon and between silicon and sapphire. The joined materials can sustain typical post-joining device process such as OMCVD growth, wet and dry etching, thin film deposition, and thermal annealing.
