Title: Method and apparatus for controlling a rotary magnet type multi-phase electric motor
Inventor: KOJIMA SADAAKI
IPC: H02P21/00
Filed: 1997-03-27
Granted: 2001-05-28
Abstract: The present invention provides a method of controlling a rotary magnet multi-phase synchronous motor and the apparatus based on this method by installing a position detector on the rotary magnet multi-phase synchronous motor to increase the permissible range of installation accuracy and automatically calculate a phase correction value so as to have good controllability. The apparatus has the followings: a position detector, which is used to detect the magnet position of a rotary magnet multi-phase synchronous motor 1; and the drive unit 43, which is used to drive the rotary magnet multi-phase synchronous motor. The rotary magnet multi-phase synchronous motor 1 having the position detector 2 is driven by the drive unit 43. After the rotary magnet multi-phase synchronous motor 1 reaches a constant speed, current and drive voltage of the rotary magnet multi-phase synchronous motor 1 are measured. The current, drive voltage, constant value of motor 1 and the constant speed stated above are used to calculate a phase correction value between a biaxial coordinate axis used for control based upon the installation error of the position detector 2 and a biaxial coordinate system from conversion of a poly-phase AC coordinate system. The rotor position, which is detected by the position detector 2, of the rotary magnet multi-phase synchronous motor 1 is corrected based on this phase correction value.

Title: Omnidirectional antenna
Inventor: LIU DUIXIAN
IPC: H03H7/38
Filed: 1997-10-29
Granted: 1999-12-21
Abstract: This invention is a novel antenna configuration that has a substantially smaller size than existing antennas tuned to a given frequency. Compact size is achieved without substantial loss in performance, making the antenna particularly suitable for hand-held devices. An antenna in accordance with the invention is preferably situated on an FR4 substrate, and includes a dipole having first and second pairs of copper radiating strips, one pair on each of the top and bottom surfaces of the substrate. Each radiating strip in a pair has a copper conductive strip coupled thereto, the strip of one radiating element being situated on the same surface of the substrate as the respective strip, with the conducting element of the other radiating strip being disposed on the opposite surface of the substrate. The effect of the configuration is to lengthen the radiating strips without an increase in substrate dimensions, thereby allowing tuning to low frequencies for a given substrate size. An on-board matching network includes adjustable capacitance and inductance to match the impedance of the antenna with that of a connector coupled to an off-substrate transceiver. A preferred implementation of a 900 MHz antenna is described.

Title: Method for etching silicon oxynitride and inorganic antireflection coatings
Inventor: IONOV PAVEL
IPC: H01L21/302
Filed: 1999-01-26
Granted: 2001-05-28
Abstract: The present disclosure pertains to a method for plasma etching a semiconductor patterning stack. The patterning stack includes at least one layer comprising either a dielectric-comprising antireflective material or an oxygen-comprising material. In many instances the dielectric-comprising antireflective material will be an oxygen-comprising material, but it need not be limited to such materials. In one preferred embodiment of the method, the chemistry enables the plasma etching of both a layer of the dielectric-comprising antireflective material or oxygen-comprising material and an adjacent or underlying layer of material. In another preferred embodiment of the method, the layer of dielectric-comprising antireflective material or oxygen-comprising material is etched using one chemistry, while the adjacent or underlying layer is etched using another chemistry, but in the same process chamber. Of particular interest is silicon oxynitride, an oxygen-comprising material which functions as an antireflective material. A preferred embodiment of the method provides for the use of a source of carbon and an appropriate halogen-comprising plasma, to achieve selective etch of one oxygen-containing material compared with another material which contains a more limited amount of oxygen.
