  • Patent number: 10271065
    Abstract: For the purpose of providing an image encoding technique for reducing the amount of codes, in inter prediction in which motion search is performed by using a block obtained by dividing an input image and a reference image, the motion vector of the block is predicted by selecting from the motion vectors of the surrounding blocks. Further, in the method of calculating a differential vector and then performing encoding, the number or positions of candidate blocks from which a prediction vector is selected are changed block by block or frame by frame and thereby adaptive and efficient video image compression is performed.

  • Publication number: 20190091956
    Abstract: A tire having a rubber member formed by winding a ribbon rubber in uninterrupted fashion about a rotational axis of the tire. The rubber member has a parallel portion at which the ribbon rubber is parallel to a tire circumferential direction at an end toward an exterior in a tire width direction, and an inclined portion at which the ribbon rubber is inclined with respect to the tire circumferential direction in such fashion as to cause the ribbon rubber to be directed from the parallel portion toward an interior in the tire width direction. The ribbon rubber from which the parallel portion is formed is wound in the tire circumferential direction for a wrap angle of not 360° but N ° (N=210 to 300).

  • Publication number: 20180178470
    Abstract: A method of manufacturing a pneumatic tire includes forming a green tire. Forming the green tire includes: a first step of forming a first belt portion by winding a first belt on an outer peripheral surface of an inner liner and, thereafter, forming a second belt portion by winding a second belt on the first belt portion thus acquiring a belt layer; and a second step of acquiring a reinforcing layer by winding a reinforcing belt on the second belt portion. The second step includes: a first parallel winding treatment where the reinforcing belt is wound one turn on a first circumference; a spiral winding treatment where the reinforcing belt is spirally wound in a tire width direction; and a second parallel winding treatment where the reinforcing belt is wound on a second circumference within a range of from 240°±30° with one turn set to 360°.

  • Patent number: 9605300
    Abstract: A technique for performing spectral calibration simultaneously with electrophoresis of an actual sample to be analyzed, without performing electrophoresis using a special matrix standard which is time-consuming and costly, is provided. The device for genotypic analysis is characterized by obtaining reference fluorescence spectra using a size standard and an allelic ladder, which provide information concerning known DNA fragments used for electrophoresis of an actual sample, and is characterized by performing spectral calibration for a capillary in which the allelic ladder is not used by detecting a shift amount of the fluorescence spectra of the size standard and shifting the reference fluorescence spectra using the shift amount to determine fluorescence spectra.

  • Patent number: 9247252
    Abstract: In expansion and reduction of the size of a macroblock in a moving image encoding, a compression ratio falls because an information amount for describing size information of the macroblock increases. An image decoding device includes a CU dividing unit and a CU-size storing unit. The CU-size storing unit has stored therein size information of an encoded CU in an encoding target picture to be stored and size information of all CUs in preceding and following pictures used for prediction. The CU dividing unit predicts a CU size in an encoding target position using the CU size information stored in the CU-size storing unit and determines a CU size of a final encoding target CU.

  • Patent number: 8948257
    Abstract: A technique for improving a compression rate without needing new determination information (encoding flag information) is provided. For compression of each area to be encoded, based on a skip mode (a process which does not compress information of the area to be encoded, but copies previous information of the area to be encoded), it is determined whether an existing predicted image generated by an existing encoding standard is used, or an interpolation predicted image newly generated by executing move searching between decoded images is used.

    Abstract: An electrostatic induction generator has a first substrate and a second substrate that can move relative to each other while remaining opposed to each other, an electret provided in the first substrate, and a first electrode and a second electrode provided on a surface side opposed to the electret in the second substrate. A positional relationship between the electret and the first electrode and a positional relationship between the electret and the second electrode change in association with a change of relative positions between the first substrate and the second substrate, whereby an electrostatic capacitance between the electret and the first electrode and an electrostatic capacitance between the electret and the second electrode change to output an electric power. A structure that decreases the electrostatic capacitance between the first electrode and the second electrode is provided between the first electrode and the second electrode.
