Abstract: A cooling device includes: a container in which a refrigerant is sealed; an evaporating part that evaporates the refrigerant in a liquid phase by heat reception inside the container; a condensing part that condenses the refrigerant in a gas phase by heat dissipation inside the container; and a plate-shaped or block-shaped flow path member in which a plurality of flow paths configured to transport the refrigerant in a liquid phase from the condensing part to the evaporating part by surface tension inside the container is formed in parallel.

Abstract: A method is disclosed, for encoding a signal with a three dimensional image sequence using a series of left and right images. Each image in the left image series is a picture formed by non-interlaced or interlaced scanned left line images, and each image in the right image series is a picture formed by non-interlaced or interlaced scanned right line images. The left line images contained in the left picture are merged with the right line images contained in the right picture to produce an alternately arranged left and right line merged picture. The merged picture is encoded using an MPEG-2 compliant encoder.

Abstract: A method and apparatus for adaptively selecting a coding mode for video encoding systems using the techniques of predictive coding, interpolative coding, motion compensation, discrete cosine transformation (DCT), adaptive quantization, or variable length coding. In one system, a value related to an amount of total code, which is composed of current video code and its coding parameters for each of the above coding modes, is determined, respectively, and a coding mode corresponding to the smallest value is selected. Then, the encoding is performed using the selected coding mode.

Abstract: A motion vector detecting circuit and a motion video compressing system are disclosed. The detecting circuit detect a vector which direct from a spatial location of a current macroblock to a spatial location of a reference macroblock. The detecting circuit includes a first extracting circuit, a second extracting circuit and a searching circuit. The first extracting circuit extracts upper bits from each pixel data of the current macroblock. The second extracting circuit extracts upper bits from each pixel data of the reference frame. The searching circuit searches the upper-bits-extracted reference frame for a macroblock having the strongest correlation with the current macroblock by comparing the upper-bits-extracted current macroblock with the upper-bits-extracted reference frame and outputs the spatial location of the reference macroblock. The motion video compressing system includes the motion vector detecting circuit, a transform-coding circuit, a subtracter, a comparator and a controller.
