In the refrigeration field, the research on the refrigerator using waste heat and natural energy attracts attention. Heat driven type metal hydride refrigeration system is one of the candidates. The dynamic behavior of pressure, temperature is strongly related to the metal hydride heat exchanger characteristics, such as the heat transfer mechanism and the(More)
The rotatostereoradiographic device uses an x-ray tube coupled with an image intensifier rotating through a 180 degree arc in 2.25 seconds. The rapidly rotating x-ray tube allows 180 degree-arc angiograms to be obtained with a single injection of contrast medium. Subtracted fluoroscopic angiograms can be viewed immediately after injection of the contrast(More)
