  • Publication number: 20200278321
    Abstract: The present invention provides an eddy current flaw detection device capable of applying a sufficiently strong magnetic field to a test object without using a significantly large magnet. A magnetic-field forming magnet 60 includes a base magnet piece 60a and a tip magnet piece 60b. The tip magnet piece 60b has a tip pole face 62 from which a magnetic pole is directed toward a test object 30. The tip pole face 62 has a smaller area than a base face 64 of the base magnet piece 60a, the base face 64 being located on the opposite side of the magnetic-field forming magnet 60 from the tip pole face 62.

  • Publication number: 20130258217
    Abstract: In one embodiment, a stereoscopic image display device includes a display panel having a first display area for performing a two-dimensional display mode or a three-dimensional display mode selectively and a second display area performing a display mode different from the selected display mode in the first display area. A liquid crystal lens unit having first and second substrates and liquid crystal layer therebetween is arranged in front of the display panel for forming a liquid crystal lens corresponding to the three-dimensional display. The relation of a distance and a potential difference between counter electrodes arranged on the second substrate adjacent each other sandwiching a boundary display area between the first display area and the second display area is set so that generation of a different lens from a lens form to perform the three-dimensional display mode in either one of the first and second display areas is suppressed.
