A screw compressor includes a casing having low and high pressure spaces, a screw rotor inserted in a cylinder part of the casing, and a slide valve disclosed in the cylinder part. The screw rotor has a plurality of helical grooves forming a compression chamber. The slide valve is moveable along an axis of the screw rotor and faces an outer periphery of the screw rotor to form a discharge port to communicating the compression chamber with the high pressure space. Fluid in the low pressure space is sucked into the compression chamber, compressed, and then discharged to the high-pressure space when the screw rotor rotates. The slide valve includes a sealing projection located on a back surface of the slide valve opposite to the screw rotor, and separating the low and high pressure spaces from each other when the sealing projection is in slidable contact with the casing.

A screw compressor includes a casing and a compression mechanism accommodated in the casing. The compression mechanism has a screw rotor, a gate rotor and a communication mechanism. The sate rotor has a flat plate shape. A rotational axis of gate rotor is orthogonal to a rotational axis of the screw rotor. The communication mechanism is arranged to communicate a high pressure space and a low pressure space in the casing.

The present invention allows usable information to be selected by comparing information regarding encoding with conditions regarding encoding processing. When delay modes, picture structures, and pulldown modes do not match each other between previous encoding time and re-encoding time, parameters are not reused. When they match and image frames do not match, a picture type is reused. When a bit rate in the previous encoding is smaller than that in the current encoding and a chroma format is larger than the current chroma format, a picture type and a motion vector are reused. When the conditions are not satisfied, parameters are supplied and received and a determination is made as to whether or not chroma formats match each other. When the chroma formats do not match each other, picture-type information, motion-vector information, and quantization-value information are reused. When the chroma formats match each other, stream data input to a decoding unit is output. The present invention can be applied to an encoding unit, an encoding device, or a transcoder.

A system for coding an I-picture that satisfies a predetermined condition using parameter information. When it is determined that a picture type is the I-picture, it is determined whether or not the phase of a macro block in previous coding agrees with that of the macro block of present coding. When the phases of the macro blocks agree with each other, it is determined whether or not amount of generated code in a unit of picture in decoding≦target amount of code×α is satisfied. When the condition is satisfied, it is determined whether or not an image frame of previous coding is the same as that of previous coding. When the image frames are not the same, the information of a picture type, motion vector, and a quantized value included in the parameter information is reused, whereas when the image frames are the same, the stream data input to a decoder is output. When the above condition is not satisfied, the parameters are not reused. The present invention can be applied to a coder, a coding apparatus, an information recording apparatus, an information reproducing apparatus, or a transcoder.

An apparatus and method of detecting editing points of image data in order to select items of information that can be reused according to the status of the image data including the detected editing points is provided. Accordingly, an image processing apparatus may include a data converter for performing at least part of coding processing on the image data, a detector for detecting an editing point of the image data, and a controller for determining, based on the editing point detected by the detector. A reuse disable period is a period in which information concerning previous coding processing performed on the image data is not reusable.

A refrigeration apparatus includes two sub passages which are branched from a main passage located between a condenser and an expansion part and which are connected to a compressor. On the sub passages are provided supercooling-use expansion parts, and supercooling-use heat exchangers for performing heat exchange between a refrigerant on an outlet side of the supercooling-use expansion part and a refrigerant of the main passage. Therefore, each time the refrigerant of the main passage passes through the two supercooling-use heat exchangers the degree of liquid supercooling of the refrigerant is increased.

摘要:
To generate coded data including additional coding information, non-compressed image data is first supplied. The number of predetermined units (i.e.: frame) of the non-compressed image data is counted. Coding is performed on the supplied non-compressed image data. Information for specifying a coding device stored in a memory and the unit count number are obtained and are combined to generate additional coding information. The additional coding information is added to coded data and the resulting data is then output. It is predetermined whether the supply of the non-compressed image data is completed. If not, the number of frames is counted and the following steps are repeated. If the supply of the non-compressed image data is completed, the process is completed.
