  • Patent number: 9807369
    Abstract: A 3D imaging apparatus includes: a first image capturing camera generating a base image to be used for obtaining a first range image showing a three-dimensional character of an object; a second image capturing camera generating a reference image to be used for obtaining the first range image; a stereo matching unit searching for corresponding pixels between the base image and the reference image, and generating a first range image by calculating a disparity between the corresponding pixels; and a light source emitting to the object infrared light whose intensity is modulated. The first image capturing camera further generates a second range image by receiving a reflected light in synchronization with the modulated intensity. The reflected light is the infrared light reflected off the object. The second range image includes range information on a range between a point of reflection off the object and the first imaging unit.

  • Patent number: 9048027
    Abstract: A fluid dispersion obtained by mixing oxide particles and water is sprayed to a raw aluminum foil from a direction opposite to a travelling direction of the raw aluminum foil while the raw aluminum foil is allowed to travel. In this way, a roll-pressed mark of the raw aluminum foil is eliminated, and thus aluminum foil for aluminum electrolytic capacitor electrode is produced. Pyramidal-shaped recesses each having an acute angle tip are present all over a surface of the aluminum foil.

  • Publication number: 20110291162
    Abstract: Each of pixels 10 arranged in an array pattern includes a photoelectric conversion element 11, a transfer transistor 13 for transferring charges to a floating diffusion layer 12, and an amplifier transistor 14 for outputting the transferred charges to an output line. An insulating isolation part 22 isolates the adjacent photoelectric conversion elements 11, and isolates the photoelectric conversion element 11 and the amplifier transistor 14. The insulating isolation part 22 constitutes a first region A between the photoelectric conversion elements 11 where the amplifier transistor 14 is not arranged, and a second region B between the photoelectric conversion elements 11 where the amplifier transistor 14 is arranged. First and second isolation diffusion layers 23 and 24 are formed below the insulating isolation part 22, and the second isolation diffusion layer 24 is wider than the first isolation diffusion layer 23 in the first region A.

  • Patent number: 7172344
    Abstract: Precise V-grooves allowing an optical fiber to project are formed in respective main surfaces of an upper plane substrate and a lower plane substrate. The optical fiber is mounted on one plane substrate, and a multi-layer film filter 2 is inserted into a filter insertion groove 1 crossing the precise V-groove in the main surface of the other plane substrate. Then, using the projecting optical fiber and the other precise V-groove as a guide rail, two plane substrates grapple the multi-layer film filter to fix and mount the filter. In an optical filter module obtained in this manner, a process of adjusting an optical axis between input/output optical fibers is eliminated, and displacement of the inserted optical filter is reduced.
