  • Publication number: 20150121686
    Abstract: A laminated iron core manufacturing method in a blanking die apparatus having multiple machining stations is provided. The method includes feeding a belt-shaped workpiece progressively in a longitudinal direction in the blanking die apparatus, operating cutting tools provided in the respective machining stations simultaneously to perform predetermined blanking operations on the progressively fed workpiece and finally perform a contour blanking operation on the workpiece so as to form core pieces, and laminating the core pieces within or outside the blanking die apparatus to thereby manufacture a laminated iron core. An auxiliary cutting tool is operated to form a disposal hole by partly blanking a scrap forming area of the workpiece simultaneously with the operations of the cutting tools of the multiple machining stations, to thereby secure a load balance of the blanking die apparatus in the feeding direction.

  • Publication number: 20150032394
    Abstract: A battery monitoring unit monitors at least one from among: (i) the attachment state of secondary battery pack; (ii) the low state of a battery voltage VBAT; and (iii) the state of whether it is possible or impossible to use the secondary battery. A battery measurement unit measures the battery voltage VBAT, a charge/discharge current IBAT, and a temperature T of the secondary battery pack, and converts the measured values into digital data. A charging circuit is configured to charge the secondary battery pack using DC voltage from an external power supply based on the state information detected by the battery monitoring unit and the information measured by the battery measurement unit. A coulomb counter measures the charge/discharge current IBAT at predetermined time intervals, and integrates the measurement value, thereby calculating the sum total of the charged/discharged amount. The battery management circuit is monolithically integrated on a single semiconductor substrate.

  • Publication number: 20140230236
    Abstract: There is provided a method for producing a rotor laminated core by laminating circular core pieces. The method determines a first blanking area, a second blanking area and a third blanking area in the magnetic steel board, wherein the first blanking area defines a shape of the core piece, the second blanking area defines a shape of a magnet-insertion hole, and the third blanking area defines a shape of an arbitrary part in the magnetic steel board. The method also forms a temporary aperture in the second blanking area, forms a thinning part which extends from the temporary aperture to the third blanking area, and blanks the first blanking area, the second blanking area and the third blanking area, thereby producing each circular core piece including the thinning part and magnet-insertion holes formed in a circumferential direction.

  • Publication number: 20140167695
    Abstract: A lock device locks a locking subject to a power port. The lock device is provided with a lock mechanism including a lock member that is movable between a lock position and an unlock position. The lock mechanism moves the lock member to the lock position to lock the locking subject and moves the lock member to the unlock position to unlock the locking subject. A location registration unit registers, as a registered location, a location where switching of the locking subject between a lock state and an unlock state is prohibited or permitted. A location acquisition unit acquires a present location of the lock device. A switching control unit compares the present location with the registered location and controls the lock mechanism based on the comparison to switch the locking subject between the lock state and the unlock state.
