  • Publication number: 20080061773
    Abstract: A method of evaluating can evaluate the bias magnetic field strength of hard films that construct a magnetoresistance effect read head, the magnetic coercivity of the hard films, and variations in the magnetic domain of shield films from measurement results for the resistance-parallel magnetic field strength characteristics. A magnetizing magnetic field is applied in a direction parallel to the air bearing surface of a magnetoresistance effect read head equipped with hard films to magnetize the hard films in a direction of a horizontal bias magnetic field applied to a free layer of the read element. After this, the resistance of the read element is detected and the resistance-parallel magnetic field strength characteristics of the read head are measured while applying a test magnetic field with increasing and decreasing intensity in a direction parallel to the horizontal bias magnetic field.

  • Patent number: 7289892
    Abstract: The present invention provides inspection of a transmission with higher precision and in a shorter period of time. Before a finished A/T is inspected, a V/B ASSY and an ECU are inspected together by a V/B tester in a subsidiary line. A solenoid current command value (a characteristic value inherent in the A/T) for a linear solenoid of the V/B ASSY is corrected and written into the ECU through CAN communication. Spring load of a return spring SP and stroke of the piston of a hydraulic servo for a frictional engagement element are measured. Actually measured values or corrected values of the spring load and the stroke are stored. In the final inspection of the A/T a finished-product tester reads the stored characteristic values and transmits them to the ECU integrated with the A/T through CAN communication. The characteristic values are then written into the ECU. The finished-product tester inspects the finished A/T product, using the characteristic values thus written into the ECU.

  • Publication number: 20070223256
    Abstract: The present invention provides a power device including a converter part (2) for converting an AC voltage to a DC voltage; an inverter part (3) for converting the DC voltage outputted from the converter part (2) to the AC voltage; and a transformer (4) having an inductance forming a series resonance circuit together with an electrostatic capacity of a load (20) to boost the AC voltage outputted from the inverter part (3). In the power device, an inductance (7) is connected to the output part of the inverter part (3) in parallel with the transformer (4). Thus, in a discharge part 6 provided in the load (20), since when a discharge is not generated, a recovery current is not supplied to a circulating current diode in the inverter part (3), or the quantity of the recovery current is reduced, the heat generation of the circulating current diode can be suppressed without increasing the number of elements of the circulating current diode.

    Abstract: The magnetic sensor is capable of improving variations of output power and asymmetric diversity of output signals of a magnetoresistance effect element. The magnetic sensor comprises hard films sandwiching the magnetoresistance effect element, and the hard films apply bias magnetic fields to the magnetoresistance effect element. Each of the hard films includes: a wide section, whose thickness in a height-direction is higher than that of the magnetoresistance effect film; and a link section, whose thickness in the height-direction is gradually reduced toward the magnetoresistance effect element, being extended from the wide section to a side face of the magnetoresistance effect element.

Further, there is provided a sputtering target for producing the transparent conductive film. In particular, there is provided a sputtering target composed of indium oxide and cerium oxide, characterized in that in the observation of crystal peaks by X-ray diffractometry, the presence of peaks ascribed to indium oxide and cerium oxide is observed, and that in the EPMA measurement, the diameter of cerium oxide particles dispersed in indium oxide is measured as being ?5 ?m. A transparent conductive film is formed by a sputtering technique with the use of this sputtering target.

  • Patent number: 7050882
    Abstract: When a working condition is set, if an operator sets the working condition, a control device (1) obtains an expected load factor of a laser oscillator (2) based on the set working condition, and displays the load factor as a working condition check bar (8) on a display device (3). The operator adjusts the working condition so that a load factor of the laser oscillator (2) stays within a predetermined range while watching the working condition check bar (8) and determines an appropriate working condition. Therefore, it is possible to prevent excessive load from being applied to the laser oscillator (2) at the time of actual working.
