  • Publication number: 20120318637
    Abstract: When one side (11b) of the article to be inspected (10) faces the front side of a conveyance device (30) and the first region (R1) of a mounting member (20) is in contact with a first resistance application portion (33A), the sliding between the first region (R1) and the first resistance application portion (33A) is suppressed. Thereby the mounting member (20) moves forward while rotating in the clockwise direction (refer to the reference numeral 5A). Next, when the second region (R2) comes into contact with the first resistance application portion (33A) as indicated by the reference numeral 5B, sliding occurs between the second region (R2) and the first resistance application portion (33A), and the mounting member (20) stops rotating. Then, the mounting member (20) comes into contact with a second resistance application portion (33B), and the mounting member (20) moves forward while rotating in the clockwise direction (refer to the reference numeral 5C).

  • Publication number: 20110174652
    Abstract: There is provided a display system and the like which allow the containers to be displayed with marks thereon facing a predetermined direction. The container 20 is first supplied to the display device 30 with the projecting portion 24 positioned above the upper guide 35. If the container 20 is supplied with the first and second identification marks 23a and 23b facing the width direction of the display device 30 as reference numeral 4A, the projecting portion 24 is supported by the left-hand-side and right-hand-side upper guides 351 and 352. Thereafter, the container 20 moves frontward while rotating clockwise as reference numeral 4A. When the first and second flat portions 2410 and 2420 face the width direction of the display device 30 as reference numeral 4B, the container 20 falls (down) to the placement unit, and moves to the front of the display device 30 without making circumferential rotation.

  • Publication number: 20090000701
    Abstract: An R-T-B exchange spring magnet alloy ingot is provided, wherein the R-T-B exchange spring magnet alloy ingot comprises at least one element selected from Nd, Pr, and Dy in a total amount of 1 to 12% by atom and B in an amount of 3 to 30% by atom, with a balance being T (T represents a substance predominantly comprising Fe, with a portion of Fe atoms being optionally substituted by Co, Ni, Cu, Al, Ga, Cr, and Mn). The R-T-B exchange spring magnet alloy ingot is produced through formation of a composite of crystal grains of a hard magnetic phase and crystal grains of a soft magnetic phase. The R-T-B exchange spring magnet alloy ingot contains crystal grains of a hard magnetic phase having a grain size of 1 ?m or less and crystal grains of a soft magnetic phase having a grain size of 1 ?m or less in a volume of at least 50% on the basis of the entire volume of the alloy.

  • Patent number: 7431070
    Abstract: One object of the present invention is to provide a rare earth magnet alloy ingot, which has improved magnetic properties. In order to achieve the object, the present invention provides a rare earth magnet alloy ingot, wherein the rare earth magnet alloy ingot comprises an R-T-B type magnet alloy (R represents at least one element selected from among rare earth elements, including Y; and T represents a substance predominantly comprising Fe, with a portion of Fe atoms being optionally substituted by Co, Ni, Cu, Al, Ga, Cr, and Mn) containing at least one element selected from among Nd, Pr, and Dy in a total amount of 11.8 to 16.5% by atom and B in an amount of 5.6 to 9.1% by atom; and wherein as determined in an as-cast state of the alloy ingot, R-rich phase that measures 100 ?m or more is substantially absent on a cross section.
