Abstract: 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.

Abstract: 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.

Abstract: A communication apparatus for interfacing various types of signals with different bit-rates is provided. The communication apparatus includes a receiving part receiving input signals, generating frames of a predetermined common format containing control information of the input signals and determining whether the frames are valid and a control part receiving the frames from the receiving part and performing a predetermined internal process based on the result of the determination.

Abstract: A method for preparing a carbon-containing composition is disclosed which comprises the steps of introducing, into a hot gas, a dispersion obtained by dispersing, in a decomposable carbon compound, a metal oxide and/or a metal compound which can be converted into the metal oxide by heating, to form a carbon-containing composition containing simple carbon and the corresponding metal oxide; and then collecting the formed carbon-containing composition. This carbon-containing composition is useful for the manufacture of a ceramic powder for sintering.

Abstract: Oil passages 12 for lubricating and cooling a piston pin 10 are provided in such a manner as to each open to an oil ring groove 5 of a piston 1 and to a piston inner side surface 2b of a piston pin supporting part 2 at portions in the vicinity of an upper end of a piston-pin hole 2a through the piston pin supporting part 2. The oil passages 12 are provided diagonally relative to an axis of the piston-pin hole 2a.

Abstract: 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.

Abstract: A method of regio-and stereoselective hydrolysis to deprotect an acylated hydroxy group in acylated carbohydrates, which contributes to synthesis of complex oligosaccharides, is provided. The method utilizes catalytic antibodies as hydrolase.

Abstract: A carbon-containing mixture is obtained by collecting a dispersed phase mixture from an aerosol which has been formed by introducing a decomposable carbon compound and a decomposable metallic compound into a hot gas containing steam.Since this carbon-containing mixture is extremely high in uniformity and consists of extremely fine particles, it can afford after heat treatment a metal carbide of high quality.
