Patent TW-591301-B (TW)
Title: Illuminating unit and liquid crystal display device using the same
Inventor: WATANABE TOMOYUKI
IPC: F21V8/00
Filed: 1998-09-10
Granted: 2004-06-11
Abstract: According to the object of the present invention, the visibility of the conventional reflection type liquid crystal display is unsatisfactory because bright light is unavailable in a dim environment. In addition, light emitted by the EL 29 of the semitransparent type liquid crystal display is attenuated by the reflecting device 29, and hence illuminating efficiency on the liquid crystal cell 21 is degraded and display content is not easy to recognize. To solve the problem, a reflection member 6 is arranged on the back or inside of liquid crystal cell 1 of this liquid crystal display device, and also a light guide plate 8 is arranged with its smooth surface 8e positioned on the front side of the liquid crystal cell 1. Therefore, it is possible to view a display of the liquid crystal cell 1 by external light when the surroundings are light. Moreover, when the surroundings are getting dark, the reflection plate 6 is irradiated with light from a light source 9 through the light guide plate 8. Therefore, the light is not attenuated compared with a conventional one and it is possible to make the display easy to watch.

Title: Defect-tolerant high bandwidth memory system, memory module, and method of accessing non-defective memory
Inventor: TAYLOR RICHARD MICHAEL
IPC: G11C11/34
Filed: 1999-01-25
Granted: 2001-07-21
Abstract: A defect-tolerant high bandwidth memory system (20) comprises a controller (22), one or more memory modules (24) each provided with one or more memory devices (28), and a high bandwidth channel (26) for connecting the controller (22) to each module (24) and for carrying data therebetween.

This write precompensation device simply enables allowance to be made for the influence of a large number of preceding symbol values on a transition to be recorded. When the device is combined with a known write compensation device it suffices to use a simple filter.

Title: Shadow mask of color cathode ray tube and the design method thereof
Inventor: HU YU-SHIN
IPC: H01J29/07
Filed: 1999-10-12
Granted: 2001-10-21
Abstract: The present invention is a shadow mask of color cathode ray tube and the design method thereof, mainly by elongating the length of the aperture of the shadow mask on the shadow mask of the color cathode ray tube, so that the ratio of the length of the bridge between adjacent apertures to the length of the aperture is reduced to reduce the surface area of the shadow mask, and thereby reduce the bombarding area on the shadow mask by the tri-color electron beam excited by the electron gun of the color cathode ray tube, effectively reduce the thermal energy generated by the bombardment of electron beam of the shadow mask. The shadow mask is not prone to have thermal deformation or doming phenomena to ensure the aperture of the shadow mask will project the tri-color electron beam accurately onto the phosphor deposit on the inner corresponding position of the display screen of the color cathode ray tube, which effectively raises the brightness, color purity and color purity adjustment margin.

Title: A novel method for fabrication of germanium-68 sealed sources
Inventor: CHENG WU-LONG
IPC: G21F5/015
Filed: 2000-05-04
Granted: 2001-05-28
Abstract: This invention deals with a novel method for the fabrication of 68 Ge sealed source, which is commonly used in nuclear medicine applications, to calibrate a positron emission tomography scanning system for activity measurement. The related fabrication process is simply described as follows: the millicuries 68 Ge presented in a high  concentration of nitric acid solution is primarily shaken with an appropriate amount of silica gel as an inorganic adsorbent for 20 to 40 minutes. After centrifugation, the supernatant is discarded. Most of the 68 Ge can be adsorbed onto this adsorbent. The adsorbent matrix is further purified washing twice repeatedly with the same acidity of nitric acid in order to remove the silver radionuclide impurities. The 68 Ge adsorbed on this adsorbent is then dried, loaded directly into a specific dimension of stainless steel tube or polyacrylic vessel, and sealed eventually. The results obtained from the quality assurance testing indicate that this fabricated 68 Ge sealed source has the advantages of well-sealed property, good homogeneity of radioactivity distribution, no radioactivity leakage and contamination, high radiation resistance of the adsorbent, and ease of preparation, loading, and handling.

Title: Compact multilayer BALUN for RF integrated circuits
Inventor: MOURANT JEAN-MARC
IPC: H03H7/42
Filed: 2000-11-10
Granted: 2002-08-21
Abstract: A compact BALUN transformer comprises a primary and a secondary conductor loop. Each of these loops are disposed in a substantially flat spiral configuration. However, one of these loops, other the primary or the secondary, is preferably disposed in a multi-layer (stacked) configuration. The stacking of at least one of the primary or secondary layers in a multi-layer arrangement provides an increase of impedance in one of the loops. This increased impedance for impedance matching purposes comes with the advantage that parasitic capacitance between primary and secondary layers as would normally be introduced in a multi-layer configuration is absent. In another embodiment of the present invention, both conductor loops are disposed in a multi-layer configuration. Such configurations are particularly useful for 1 to 1 impedance matching conditions and for somewhat lower frequency BALUN circuits.
