Abstract: A coding apparatus and method is disclosed by which quantization index data can be determined without referring to a virtual buffer capacity initialized in response to a scene change. ME residual information is acquired first, and it is discriminated whether or not the ME residual information is higher than a threshold value. If it is discriminated that the ME residual information is higher than the threshold value, then the initial buffer capacity of a virtual buffer is updated. On the other hand, if it is discriminated that the ME residual information is equal to or lower than the threshold value, then it is discriminated whether or not the picture being currently processed is a picture next to a scene change or is a next picture of the same type as that of a picture with which a scene change has occurred. If it is discriminated that the picture being processed is a picture next to a scene change or a next picture of the same type, then the initial buffer capacity is calculated and updated.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: The present invention can code an I-picture that satisfies a predetermined condition using parameter information. When it is determined at step S1 that a picture type is the I-picture, it is determined at step S2 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 at step S3 whether or not amount of generated code in a unit of picture in decoding?target amount of code×? is satisfied. When the condition is satisfied, it is determined at step S4 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.

ME residual information is acquired first, and it is discriminated whether or not the ME residual information is higher than a threshold value. If it is discriminated that the ME residual information is higher than the threshold value, then the initial buffer capacity of a virtual buffer is updated. On the other hand, if it is discriminated that the ME residual information is equal to or lower than the threshold value, then it is discriminated whether or not the picture being currently processed is a picture next to a scene change or is a next picture of the same type as that of a picture with which a scene change has occurred. If it is discriminated that the picture being processed is a picture next to a scene change or a next picture of the same type, then the initial buffer capacity is calculated and updated.

Abstract: Present invention provides a single screw compressor from which only a small amount of gas to be compressed leaks and which can be manufactured at low costs. There are provided a screw rotor 1 having six grooves 2, 2, . . . and a gate rotor 4 having 12 teeth 5, 5, . . . which are installed in a casing. Since six, which is the number of the grooves of the screw rotor 2, and twelve, which is the number of the teeth 5 of the gate rotor, have a common divisor, only predetermined teeth 6 are engaged with a groove 2. Therefore, engagement combinations of the grooves 2 and the teeth 5 are divided into six groups. In each of these groups, dimension accuracy is controlled so that the grooves 2 and the teeth 5 engaged each other have appropriate clearances. Since manufacture is easier when dimension accuracy is controlled within each group than when dimension accuracy of all grooves 2 and teeth 5 is controlled at one time as in a conventional case, this single screw compressor becomes inexpensive.

Abstract: A history-information/parameter-reuse disable period is set, starting from a P picture temporally one picture before an editing point to the first I picture after the picture subsequent to the editing point for a predetermined number n (for example, n=8) of pictures. If the first I picture is positioned close to an editing point only for a few pictures, the reuse of parameters or history information is not started from this I picture, but is started from the I picture after the picture subsequent to the editing point for a predetermined number n (for example, n=8) of pictures. The present invention is applicable to coding devices or transcoders.

Abstract: 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.

Abstract: A reusable quantization value Qref included in history information or parameter information is obtained in step S21. In step S22, it is judged whether or not the quantization value Qref obtained in step S21 is smaller than a predetermined minimum quantization value Qmin. If it has been judged that the quantization value Qref is smaller than the predetermined minimum quantization value Qmin, the process proceeds to step S23, where the quantization value Q is set at Qmin, and then the process is completed. If it has been judged that the quantization value Qref is not smaller than the predetermined minimum quantization value Qmin, the process proceeds to step S24, where the quantization value Qref is reused and is set as the quantization value Q, and then the process is completed. The present invention can be applied to an SDTI CP-ASI converter or a long GOP encoder.

Abstract: When a driving shaft rotates, a piston (9) revolves around the driving shaft in a cylinder room (6a) with supported by a swing bush (32) as a supporting point through a blade (31). Discharge ports (22) are formed in a front head (7) and a rear head (8) respectively and are disposed to be located in the proximity of the blade (31) and to communicate with a high pressure room. A semicircular portion of the discharge port (22) overlaps with the swing bush (32) and the cylinder (6). A pair of upper and lower cut parts (41) are each formed by cutting away an outer peripheral edge of the swing bush (32) and an inner peripheral edge of the cylinder (6) which are overlapped with the discharge port (22).

Abstract: In a horizontal type scroll compressor an external end of a volute (2b) of a fixed scroll (2) is extended near to an external end side of a volute (3b) of a movable scroll (3). By the extension of the volute (2b), inlet ports (22, 23) opening to compression rooms (RA, RB) respectively are disposed near to each other and are located at an upper level in a closed casing (1). An inlet passage (24) is formed at the top of a housing (4) which divides the closed casing (1) into a compression element chamber (12A) and a motor chamber (12B). The opening position of an inlet pipe (11) is displaced circumferentially with respect to the inlet passage (24). The inlet passage (24) is displaced circumferentially with respect to the inlet ports (22, 23) of the compression rooms (RA, RB). The inlet passage (24) is displaced forward in a traveling direction of the movable scroll (3) with respect to the inlet ports (22, 23).

Abstract: A thermal isolation arrangement for use in a co-rotating scroll refrigerant compressor includes various thermal insulation elements adapted to minimize heat transfer between hot rotating members of the scroll fluid device and the return refrigerant to be compressed, and between hot lubricant in the compressor and the return refrigerant. The thermal isolation elements of the present invention may be used individually or collectively to minimize the preheating of the inlet refrigerant so as to maintain the density of the return refrigerant being compressed to thereby increase the total efficiency of the scroll fluid device.
