Title: Constant current lighting apparatus for a discharge lamp
Inventor: TAMURA TERUO
IPC: H05B41/232
Filed: 2002-06-11
Granted: 2004-01-01
Abstract: A discharge lamp cannot be lighted at a constant current of a rated value. Thus, a life of a tube is short and the management thereof is troublesome. In addition, power required at turning on the light is about two times larger than that when the light is lighting. Thus, the larger contracted power increases the costs. Further, consumption power is large. A series circuit is composed of one end (1) of an AC power source, a choke coil (L), a mercury lamp (or a sodium lamp, or a fluorescent lamp (DL)), a condenser (C), a choke coil (L2), and another end (2) of the AC power source. An output end (3) of the choke coil (L2) is connected to an input end (4) of a primary (p) of an auto-transformer. Thus, an impedance ratio of the choke coils (L+L2) and the condenser (C) is set so that they are resonated at a third high harmonic component of the power source, whereby an apparatus capable of lighting the discharge lamp at a constant current of a rated value is completed. As a result, the life of the tube is increased, and waste consumption power caused by fluctuation of voltage is reduced by about 30%.

Title: Method for fabricating a vertical transistor in a trench, and vertical transistor
Inventor: BIRNER ALBERT
IPC: H01L27/108

Granted: 2004-03-11
Abstract: To fabricate a vertical transistor, a trench (4) is provided, the side wall (6) of which is formed by a semiconductor substrate (2) in single crystal form and the base (8) of which is formed by a polycrystalline semiconductor substrate (10). A transition region (12) comprising an insulating material is arranged between the side wall (6) and the base (8). A semiconductor layer is deposited selectively with respect to the material of the transition region (12), so that an epitaxial semiconductor layer (24) grows on the side wall (6) and a semiconductor layer (26) grows on the base (8), with a space remaining between these layers. The semiconductor layers (24, 26) which have been deposited are covered with a thin dielectric (28), which only partially limits a flow of current, and the space is filled with a conductive material (30). During a subsequent heat treatment, dopants diffuse out of the conductive material (30) into the epitaxial semiconductor layer (26), where they form a doping region (44). The thin dielectric (28) on the one hand limits the diffusion of the dopants into the semiconductor substrate (2) and on the other hand prevents the propagation of crystal lattice defects into the epitaxial semiconductor layer (26).

Title: Radio-frequency signal frequency conversion device for a low power RF receiver
Inventor: ZELLWEGER EMIL
IPC: H03D7/00
Filed: 2002-08-06
Granted: 2004-04-11
Abstract: The radio-frequency signal frequency conversion device (3) generates intermediate complex signals (IF) for a correlation stage of a low power RF receiver. In order to do this, the device includes a first selective pass-band filter (12) for filtering radio-frequency signals picked up by an antenna (2). A frequency synthesiser (20 to 25) generates first and second high frequency signals, wherein the frequency of the first signals is higher than the frequency of the second signals. This synthesiser receives reference signals from an oscillator unit (26 to 29). A first mixer unit (14) mixes the radio-frequency signals with the first signals in order to generate frequency-converted signals. A second pass-band filter (15) filters the signals from the first mixer unit, and provides signals to a second mixer unit (16) to mix them with the second high frequency signals. Finally, shaping means (17, 18, 19) for the signals provided by the second mixer unit generate the intermediate signals. The second filter is a not very selective active filter, which is integrated, in an RF/IF integrated circuit (10) with the first and second mixer units, the signal shaping means, and certain parts of the synthesiser and the oscillator unit.

Title: Enhancing compression while transcoding jpeg images
Inventor: PRAKASH RAVI
IPC: G06T9/00
Filed: 2003-10-03
Granted: 2005-06-21
Abstract: Further compression of data allowing economical storage of data for extended periods of time in high-speed access memory is performed in reduced time by performing further compression during transcoding in the transform domain and without restoring image data to its original image data form. The reduction in processing time is achieved by exploiting the large number of zero-valued quantization transform coefficients and not changing quantized transform coefficients at zig-zag scan positions where non-zero coefficients are rare during range reduction of the entropy decoded quantized transformed data. The range can be restored by computation or estimation of an altered quantization table which is stored with the further compressed quantization values. Further advantages accrue from use of JPEG packed format for the data during transcoding.
