  • Patent number: 7859683
    Abstract: Disclosed herein is an apparatus for measuring the shape of a 3D object using an interferometer. The apparatus includes a light source unit, a beam splitter, a reference mirror, an actuator, an image pickup device, and a control unit. The light source unit emits light. The beam splitter divides the light from the light source unit. The reference mirror reflects light as a reference beam. The actuator moves the reference mirror. The image pickup device acquires a plurality of interference patterns by causing the reflected beam and the reference beam to interfere with each other. The control unit measures the shape of the object from the acquired interference patterns, outputs reference mirror drive signals to the actuator, and issues an image capture command at the end of image capture time that is shorter than settling time.

  • Patent number: 7830332
    Abstract: A multi-display (e.g., dual-display) driving circuit includes a first display driving circuit configured to receive a first display signal and a second display signal from an external source (e.g., CPU) through a first interface, and to drive a first display panel in response to the first display signal and to output the second display signal through a second interface of the first display driving circuit. The second display signal is transmitted via the second interface to a second driving circuit configured to drive a second display panel. Therefore, the complexity of the wiring (e.g., through a hinge of a folding phone, and between a CPU and first and second displays) of the multi-display device may be reduced, and the electromagnetic interference (EMI) characteristics of the multi-display device may be enhanced.

  • Patent number: 7782994
    Abstract: This invention relates to an inhibitor of lead-induced stress corrosion cracking including nickel boride in the secondary side of steam generator tubes in nuclear power plants and an inhibition method using the same, and more particularly, to an inhibitor of lead-induced stress corrosion cracking, in which nickel boride is added to secondary side cooling water of the steam generator in an amount of 0.2˜6 g/l, and to an inhibition method using the same. According to this invention, when the inhibitor of lead-induced stress corrosion cracking is added to the secondary side of the steam generator tube in nuclear power plants, stress corrosion cracking of the tubes, which occurs in the lead-containing neutral or caustic solution, and a crack growth rate are decreased, thus increasing elongation. Further, a stress corrosion cracking ratio is decreased, and therefore the stress corrosion cracking resistance of metal or alloy can be improved.
