  • Publication number: 20060145917
    Abstract: It is an object of the present invention to provide a GPS receiver capable of deciding quickly a GPS satellite as a communication object while suppressing a consumption power. In order to attain the object, when a receiving portion 101 does not receive WNa in the navigation message transmitted from the GPS satellite but receives WN, the GPS receiver of the present invention predicts WNa based on the received WN, and then restores the almanac based on this. Then, the almanac is stored in an almanac storing portion 103, and a satellite position calculating portion 106 reads the almanac as the case may be, and calculates a position of the satellite based on the almanac.

  • Patent number: 6859678
    Abstract: Provided are a method and an apparatus for manufacturing a magnetoresistive element and a method and an apparatus for manufacturing a magnetic head which can reduce variation in properties of an magnetoresistive element and variation in the median of distribution. Before starting polishing, wafer information containing various types of factors in a wafer stage which may have an influence on a resistance value of a final MR film is obtained, and an S value is calculated from the information by using a statistical scheme. During a polishing step, ongoing-work-information containing various types of factors in a polishing stage which may have an influence on the resistance value of the final MR film is obtained at regular intervals. A K value is calculated from the information by using the statistical scheme. Then, an MR resistance estimate during the polishing step is calculated from the S value and the K value. When the MR resistance estimate reaches a target resistance value , polishing is stopped.

  • Patent number: 6623336
    Abstract: When electric elements are formed on a ceramic bar or the like, the positional displacement of the respective elements occurs due to a division exposing process or the like. An object of the present invention is to provide a device and a method which unify the non-polished portion of the respective elements by conducting polishing while a complicated deformation or the like is given to the ceramic bar. To achieve this object, the ceramic bar or like is held by using a jig, and a plurality of loads are applied to portions of the jig where the ceramic bar or the like is held, to thereby deform the ceramic bar or the like and polish the element in that state. In this situation the load applied points are disposed so as to avoid the boundaries of the division exposure.
