  • Patent number: 8419281
    Abstract: An inner periphery of a molded part having a step from an inner periphery of an electroformed part is molded to a nonconductive coating which covers the surface of a master. When the nonconductive coating is removed, a radial clearance having a diameter greater than that of a bearing clearance is created between the inner periphery of the molded part, which is exposed to the interior, and an outer periphery of a shaft member. A bearing member which forms the bearing and radial clearance with the shaft member is manufactured by performing electroforming on the master with the nonconductive coating formed on part of the surface of the master, thereby forming the electroformed part; then injection molding the bearing member with the electroformed part and the nonconductive coating on the surface of the master inserted into a cavity; and then removing the nonconductive coating from the bearing member.

  • Patent number: 8421907
    Abstract: An imager is provided having an imaging sensor and a focusing detector. The imaging sensor outputs image signals that have charges stored in one line of pixels. The focusing detector detects whether a subject image is in focus on said imaging sensor based on contrast values of frame image data for one image frame formed by the image signals. The imaging sensor changes a charge-storing period that is a time period for storing charges in a pixel, and lengthens the charge-storing period in the case of taking pictures under photographing conditions in which movement of a subject is expected.

  • Patent number: 8392905
    Abstract: The present invention effectively utilizes auxiliary registers and provides a compiler system which secures error detectability when the auxiliary registers are shared for plural uses. The instruction definition resource configuring unit configures, as preparation for processing by the register assigning unit, respective resources such as a register to be defined or referred to by for each instruction in an intermediate code. The instruction definition resource configuring unit detects possibility of instructions each of which is to be decomposed into plural instructions. As for an instruction to be possibly decomposed, the instruction definition resource configuring unit configures a corresponding register in the intermediate code, assuming the corresponding register used for the decomposition to be defined and referred. The register assigning unit uses the register as a general register as far as a live range of the register used for the decomposition does not overlap.

  • Patent number: 8294774
    Abstract: An imager is provided having an imaging sensor and a focusing detector. The imaging sensor reads stored charges in a positive or negative direction and outputs image data created from the read charges. The comparator calculates a differential between first image data output by said imaging sensor and second image data output by the imaging sensor immediately after the first image data is output, and determines whether the differential is larger than a first threshold value. The composer creates composite image data from the data of two images output by the imaging sensor. When the comparator determines that the differential is larger than the first threshold value, the composer creates composite image data from the second image data and negatively scanned image data that is obtained by scanning the second image in a direction that is opposite to the scanning direction of the second image data.
