  • Patent number: 7125241
    Abstract: A blow molding method includes steps of moving a split mold to a parison receiving position where a parison is supplied and receiving a parison, closing the split mold, performing blow molding at a blow molding position, and opening the split mold at a product discharge position and thereby discharging a product. The method further includes steps of: sequentially reciprocating each split mold in trains of split molds provided opposed to each other across the parison receiving position to and from a position opposed to the parison receiving position; and sequentially reciprocating the split mold disposed at the position where the split mold is opposed to the parsion receiving position to and from the parison receiving position for performing blow molding. There is also provided a blow molding apparatus for carrying out this blow molding method.

  • Publication number: 20060192456
    Abstract: A permanent-magnet rotating machine includes a rotor having a rotor core carrying on a curved outer surface multiple permanent magnets arranged in two rows along an axial direction. The permanent magnets in one row are skewed from those in the other row in a circumferential direction by a row-to-row skew angle (electrical angle) ?e. A stator having a tubular stator core in which the rotor disposed, includes stator coils for producing a rotating magnetic field for rotating the rotor. A lower limit of the row-to-row skew angle ?e larger than 30 degrees (electrical angle). A ratio, of cogging torque occurring in the absence of skew to cogging torque occurring when the permanent magnets are skewed, at a row-to-row skew angle of 30 degrees is calculated based on the cogging torque ratio, the row-to-row skew angle ?e, and B-H curve properties of the stator core.

  • Publication number: 20060164110
    Abstract: A highly-reliable semiconductor device and a method of fabricating the semiconductor device, while stably carrying out IC test, are proposed. A pad portion after an IC test using a probe is covered with a second passivation film. It is therefore made possible to protect the pad, which has partially been thinned by the IC test, from a chemical solution of wet etching used, after the IC test, for removing a barrier metal. This consequently makes it possible to suppress intrusion of a chemical solution through the pad portion into an IC chip. In the semiconductor device, the pad portion provided for the IC test using the probe and the opening provided for formation of the metal bump electrode are separated. It is therefore made possible to suppress any influence of the probe mark produced by the IC test exerted on the geometry of the metal bump electrode.

    Abstract: A permanent magnet motor 1 includes a rotor in which permanent magnets 31 are fixed. In the rotor 20, the outer peripheral shape of rotor magnetic-pole portions 24 is formed so that, in the circumferentially central portion, the distance from the center of the rotor iron core 21 is longest, and, at the inter-polar space, the distance from the center of the rotor iron core is shortest, and so that the outermost surface of the rotor magnetic-pole portions 24 forms an arc, and given that sheath thickness tc formed by the outer-side surface of each permanent magnet 31 and the outermost surface of each rotor magnetic-pole portion 24 is practically constant, and letting the thickness of the permanent magnets be the magnet thickness tm, then the relation tc/tm?0.25 is satisfied.

  • Patent number: 6989879
    Abstract: In a liquid crystal panel 1 provided with first and second substrates 1 and 3 bonded by a sealant 3, alignment layers 13 and 23 for covering electrodes 6A and 7A, respectively, are formed up to the regions overlapping the regions for forming up to 3. Accordingly, since there is no space between the alignment 13 or 23 and the sealant 3, a low twist domain does not occur in a liquid crystal 40. Therefore, the vicinity of the inner periphery of the sealant can also be effectively used as the region for displaying images.
