    摘要: A secondary storage device using a nonvolatile semiconductor memory in which individual block areas constituting the nonvolatile semiconductor memory can be used up to their limit of use. When the number of repetitions of erasure in a second block area has reached a predetermined reference value, a searching unit searches active block areas for an alternate block area. A second writing unit writes information which has been stored in the alternate block area, into the second block area. A second correspondence modifying unit associates the physical block number with the logical block number and causes a logical-physical correspondence storing unit to store the correspondence of the thus-associated block numbers. A second erasing unit erases the information stored in the alternate block area and treats the block area with the physical block number as a spare block area.

    摘要: An imaging control unit includes: a calculating unit that obtains block brightness-values of a plurality of blocks from each pixel of an image data of a frame, the image data of a frame being divided into the plurality of blocks; a limiting unit that limits to a first limit brightness-value a block brightness-value which is larger than the first limit brightness-value among the plurality of block brightness-values; and a controlling unit that controls an exposure amount of an imaging unit so that a representing brightness-value of the plurality of the block brightness-values correspond to a target brightness-value which is less than first limit brightness-value.

    摘要: A self tapping bolt which fastens a mounting member and a receiving member while the bolt cuts internal threads on an inner surface of a tap drill hole prepared in the receiving member. The bolt includes at least one groove formed near an end of a threaded portion of the bolt and a blade for cutting the internal threads. The bolt includes the feature of the blade being formed only on a rear end surface of the groove relative to a rotational direction of the bolt which is screwed into the tap drill hole.
