Title: Method and circuit configuration for power control with low switching surges for electrical loads
Inventor: GERBER TOBIAS MANFRIED
IPC: C07D311/94
Filed: 1999-02-12
Granted: 2000-12-21
Abstract: Method and circuit configuration for power control with low switching surges for electric loads which are divided electrically into at least two partial loads, whereby to achieve the required individual power, it is distributed largely uniformly among the partial loads in a certain power range. According to this method, three separate pulse pattern sequences A, B and C corresponding to the respective system half wave are formed from three successive system half waves (pattern period), with the negative half waves being rectified. Each pulse pattern sequence A, B and C switches at least one partial load over a predefined period (PWM period), with each pulse pattern A, B or C switching a maximum of 1/3 of the nominal power of a partial load (pulse pattern power) according to the maximum number of pulses per PWM period. By means of pulse width modulation (PWM) of at least one pulse pattern sequence in accordance with the total power demand, the respective load is switched over a preselectable PWM period by the number of pulses of the respective pulse pattern sequence A, B and/or C during this PWM period. The invention makes it possible to calculate in advance the current surge load of the system due to the loads and the adaptation of the loads to prevent interfering voltage changes in the power system.

Title: Integrated semiconductor-circuit with a connection-area
Inventor: SAVIGNAC DOMINIQUE DR
IPC: H01L21/822
Filed: 1999-03-16
Granted: 2000-12-11
Abstract: In an integrated semiconductor-circuit, many parallel extended doped-regions (4, 5, 6, 7) are preferably arranged below a connection-pad (3). In order to adjust a specified capacitive load of said pad (3) according to a pre-determined input-/output characteristic, a part of said doped-regions (5, 6, 7) is connected with said pad (3). The capacitance-gradation should be refined, during that time the polysilicon-areas (8, 9, 10, 11), which are arranged over the doped-regions respectively, are connected with the substrate (1) or the pad (3). In order to adjust a desired connection-resistance, a polysilicon-resistance (12), which is in the connection-line (13) connected to the pad (3), should be trimmed. The modular structure can accurately adjust the input-/output characteristic of said pad (3) without additional area-demand.

Granted: 2001-07-01
Abstract: In a motion vector detection method which performs detection of the motion vector with respect to a field image following an interlace system, a first field image is used and the motion vector regarding a second field image is detected in a specified search area. The search area when the motion vector regarding a third field image is detected is operated by comparing an inter-field distance between a field image and the third field image to be referred to with the inter-field distance between the first field image and the second field image. The motion vector regarding the third field image is detected in the search area obtained by operating above with a point the motion vector indicates regarding the second field image as a start point. According to this invention, an amount of operation in detecting a motion vector with regard to a field image of an interlace system can be reduced.

Title: Forward link inter-generation soft handoff between 2G and 3G CDMA systems
Inventor: CZAJA STANISLAW
IPC: H04B7/26
Filed: 1999-11-30
Granted: 2001-07-21
Abstract: In a CDMA cellular radiotelephone system, a soft handoff (SHO) is performed when a mobile station communicates with a new inter-generation base station, without interrupting communications with the old base station. Currently, a SHO can only be used between CDMA channels having identical frequency assignments and within the same system generation (i.e., 2G  2G, or 3G  3G, where 2G is a second generation system, and 3G is a third generation system). The proposed IS-2000 standard for a 2G  3G handoff is a hard handoff or ""break-before-make"" procedure, which greatly reduces the quality of service (QOS). The present invention allows for SHO between second and third generation CDMA systems (2G  3G and 3G  2G), by modifying the proposed messaging structure. This provides a smooth service transition when a mobile station travels from one service area (i.e., 2G), to another service area (i.e., 3G), using the SHO or ""make-before-break"" approach.

Title: Lead germanate ferroelectric structure with multi-layered electrode and deposition method for same
Inventor: ZHANG FENGYAN
IPC: C23C14/08
Filed: 2000-05-24
Granted: 2002-07-11
Abstract: The ferroelectric structure including a Pt/Ir layered electrode used in conjunction with a lead germanate (Pb5Ge3O11) thin film is provided. The electrode exhibits good adhesion to the substrate, and barrier properties resistant to oxygen and lead. Ferroelectric properties are improved, without detriment to the leakage current, by using a thin IrO2 layer formed in situ, during the MOCVD lead germanate (Pb5Ge3O11) thin film process. By using a Pt/Ir electrode, a relatively low MOCVD processing temperature is required to achieve c-axis oriented lead germanate (Pb5Ge3O11) thin film. The temperature range of MOCVD, axis oriented lead germanate (Pb5Ge3O11) thin film on top of Pt/Ir is 400-500 DEG C. Further, a relatively large nucleation density is obtained, as compared to using single-layer iridium electrode. Therefore, the lead germanate (Pb5Ge3O11) thin film has a smooth surface, a homogeneous microstructure, and homogeneous ferroelectric properties. A method of forming the above-mentioned multi-layered electrode ferroelectric structure is also provided.

Abstract: This invention provides a formation method for a film having high dielectric constant and good insulating characteristics which copes with finer and highly integrated semiconductor element, as well as a semiconductor element which utilizes it. A Si substrate 1 is washed in acidification process, etc. and heated to remove the sticking substance on its surface. The surface of an Si substrate 1 is supplied with nitrogen made into a plasma, so that by the surfactant effect of radical nitrogen, an AlN crystal layer 80 which is not lattice matched with Si crystal is formed on the surface of the Si substrate 1. Since the inter-lattice distance of the AlN crystal layer 80 substantially agrees with the lattice constant intrinsic of AlN crystal, the Al crystal layer 80 contains no stress caused by the difference in lattice constant with the Si substrate 1 as in the case when lattice matches the Si substrate 1.
