Title: Formation method of light conducting element and mold cavity structure
Inventor: LIOU JIA-LUNG
IPC: B29C45/00
Filed: 2001-07-27
Granted: 2002-08-21
Abstract: This invention provides a formation method of light conducting element and a mold cavity structure; the mold cavity is formed by fixing a mold lump having a surface with a diffusion pattern or other pattern capable of generating optical effect and using a cavity ring to set around the mold lump in a reciprocating slidable fashion. A cavity ring uses a spring or an elastic element for support to form a mold cavity with a deeper first depth. In operation; a clamping mechanism is used to push a mirror plate to seal the mold cavity; resin is injected to fill the mold cavity; and the mold or the mirror plate is pushed to retreat the cavity ring so that the mold cavity depth is compressed into a shallower second depth; the compression can increase mold pressure to obtain good pattern duplication and yield. During the above-mentioned operation, high speed and strong thrust are engaged on the contact surface between the cavity ring and the mold lump for the reciprocating slide motion and thus defective product may be obtained due to scratches around the mirror surface of the mold cavity; the example of the invention also includes deposition of a layer of diamond-like carbon (DLC) on the contact surface to prevent friction scratches and to prolong service life of such production molds.

Title: The manufacturing apparatus of Organic Light-Emitting Diode (OLED) devices
Inventor: CHEN HWA-FU
IPC: H01L21/285
Filed: 2002-04-12
Granted: 2003-03-01
Abstract: This invention is to provide an apparatus for manufacturing organic light-emitting diode (OLED) devices. This apparatus can not only continuously load metallic materials from outside without breaking the high-vacuum state of the chamber, but also directly heat these metallic materials for making metallic electrodes of OLED devices. The direct heating of metallic materials avoids harmful high-temperatures (up to 1,700 DEG C), caused by indirect heating metallic materials, which could damage OLED thin films, whose melting points are about 100 DEG C. In the vacuum chamber 15, the anode 41 and the cathode 42 of the electric power source 40 are electrically separated. After the evaporating source 50, in which the metallic materials 18 is loaded, is transported into the chamber 15, it is lifted by a holder 54 up to a position where its two ends, 52 and 53 make close contact with the anode 41 and the cathode 42, respectively. This close contact, maintained by the spring 43, is essential for passing the electric current from the anode 41, the end 52, curled tungsten wire 51, the end 53, finally to the cathode 42. This passing electric current directly heats the metallic materials 18, which is put directly on the curled tungsten wire 51, up to the desired evaporating temperatures rapidly, so that the surrounding temperatures will not rise harmfully high, compared to the any indirect heating method for evaporating metallic materials 18. Lower surrounding temperatures, therefore, protect the organic thin films underneath the metallic electrodes from burning out.

Title: Quadrature alignment in communications receivers
Inventor: MCCUNE JR EARL W
IPC: H03D7/00
Filed: 2002-05-21
Granted: 2004-04-11
Abstract: The present invention, generally speaking, takes advantage of the properties of quadrature signals to achieve precise quadrature alignment in a simple fashion. In particular, the expectation of the product of quadrature signals is zero. In accordance with the teachings of the invention, a phase error detection network therefore operates by multiplying the received quadrature signals and low-pass filtering the product to produce an error signal. When the signals are in precise quadrature relationship, the error signal will be zero. Real-time feedback control may be used to drive the error to zero. In accordance with another aspect of the invention, a variable phase shift network is achieved using a dual delay line. The difference in delay between the two delay lines is adjusted in response to the error signal to obtain precise quadrature alignment. The principles of the invention may be applied in connection with traditional mixer architectures or with switch-mode (e.g., ""aliased undersampling"") architectures.
