Title: Method for estimating the magnetic pole location of a synchronous motor and control device of synchronous motor
Inventor: IDE KOZO
IPC: H02P6/08
Filed: 2002-03-21
Granted: 2003-11-11
Abstract: This invention intends to provide a method for estimating the magnetic pole location of a synchronous motor and a control device of a synchronous motor. According to this invention, it is possible to reliably detect the magnetic pole location of a synchronous motor and stably control same motor even when the load of same motor is high or fluctuates dramatically. A coordinate converter (8) converts the detected current (is) to an impedance observation axis shifted from an estimated location theta^ of the magnetic pole by 45 degrees. A high frequency impedance estimator (10) estimates the high frequency impedances Zdm, Zqm at two points, respectively, having an electrical angle of lead by 45 degrees and an electrical angle of lag by 45 degrees from a gamma axis. A first magnetic pole location estimator (13) estimates the estimated value theta^ of a first magnetic pole location so as to nullify the deviation of the high frequency impedances Zdm, Zqm. A current command value idelta* is inputted to a second magnetic pole location estimator (14), then a compensation angle thetar^ of the inner phase difference is estimated, and the compensation angle thetar^ is subtracted from the estimated value theta^ of a first magnetic pole location to obtain a second magnetic pole location thetac^ to be outputted.

Title: Semiconductor substrate, field-effect transistor, and their production methods
Inventor: SHIONO ICHIRO
IPC: H01L29/78
Filed: 2003-02-06
Granted: 2004-10-11
Abstract: There is a first layer formation step, second layer formation step, heat treatment step and polishing step; the first layer formation step sets the thickness of the first SiGe layer to be thinner than twice the critical thickness, which is the thickness at which increasing the thickness produces dislocations and lattice relaxation does not occur; and the second layer formation step makes the Ge compositional ratio of the second SiGe layer lower than the highest value in the layer of the Ge compositional ratio in at least the first SiGe layer, or the Ge compositional ratio of the SiGe layer at the contact surface with Si, and moreover, at least partially forms a sloping composition region in which the Ge compositional ratio gradually increases toward the surface. As a result, along with the threading dislocation density being low and surface roughness being small, deterioration of the surface and boundary roughness during heat treatment in a device manufacturing process or the like is prevented.

Abstract: A video compression system is disclosed that is optimized to take advantage of the types of redundancies typically occurring on computer screens and the types of video loss acceptable to real time interactive computer users. It automatically adapts to a wide variety of changing network bandwidth conditions and can accommodate any video resolution and an unlimited number of colors. The disclosed video compression encoder can be implemented with either hardware or software and it compresses the source video into a series of data packets that are a fixed length of 8 bits or more. Sequences of one or more of these packets create unique encoding ""commands"" that can be sent over any network and easily decoded (decompressed) with either software or hardware. The commands include 3 dimensional copying (horizontal, vertical and time) and unique efficiencies for screen segments that are comprised of only two colors (such as text). Embodiments are also disclosed that improve the video compression depending on the popularity of pixel colors.
