摘要:
A heat driven acoustic type pulse tube cryocooler has metal knit installed within a driving section cooling a driving gas of an application device using a principle of high temperature superconductivity, and then homogeneously heats the driving gas by way of premixed combustion so that the driving gas generates an acoustic having a predetermined frequency. The orifice installed within a reservoir controls the amount of the driving gas running between the cold reservoir and the pulse tube to constantly maintain a pressure of the cold reservoir. Therefore, the driving gas repeats the process of the compression and expansion centering around the pulse tube, thereby cooling the application device.

The present invention relates an absorptive high temperature desorber for mechanically narrowing the width of the combustion area, and an absorption chiller-heater using the absorptive high temperature desorber. The high temperature desorber comprises a plurality of combustion chambers, a group of liquid ducts arranged in the perpendicular direction in the combustion chambers, and the distribution chambers independently supplying a mixing gas to the plurality of combustion chambers. Therefore, the high temperature desorber can form flame independently and variably in the combustion chamber, and has a mechanically small width.

An image data decoding apparatus and method are based on an availability of reference data. The image data decoding apparatus may include a core to process decoding of image data, and an availability determining device to receive, from the core, availability verification request information with respect to a reference area of a first frame included in the image data, to determine an availability with respect to the reference area based on the received availability verification request information, and to transmit, to the core, the determined availability. When the reference area is available, the core may process decoding of a second frame based on the reference area.
