    摘要: Cavitation is reduced in a rotary pump while the pump performance is maintained by utilizing a low-temperature fluid source already present in the pump system. The fluid from the low-temperature fluid source receives heat from the fluid flowing to the pump, thereby lowering its temperature and the saturated vapor pressure, which increases the allowable margin for a decrease in fluid pressure and reduces the occurrence of cavitation. The pump system may be used for a liquid rocket engine. The fluid velocity of the fluid directed to the pump is low before releasing heat, so there is only a slight pressure loss at the pump. Accordingly, the temperature is lowered and the occurrence of cavitation is reduced within the pump.

    摘要: Video signals input to a hybrid recorder are output to the main unit of a computer as video signals. The hybrid recorder records the video signals in a built-in hard disk, and also replays the signals from the hard disk, the signals being output to a picture effects device as video signals. The picture effects device applies certain effects to the video signals, which are then output to the main unit as video signals. The main unit displays the image of the video signals and the image of the video signals on a monitor. Thus, editing can be performed easily and speedily, while adding effects.

    摘要: In a recording support mode, states of an HD device and a VTR are detected, and if the two are normal, video signals are recorded in both. The signal recorded in the HD device can be reproduced almost simultaneously with the recording upon request. Where either device is abnormal, the video signal is recorded in the normal device. In the reproduction support mode, the reproduction position of the HD device is detected, the VTR video tape is brought to that position, it is checked whether or not the video signal the same as the video signal which has been reproduced by the HD device is recorded based on the time code of the video signal recorded at that position, and the reproduction of the same video signal is carried out simultaneously with the HD device. Thereafter, where an abnormality occurs in the HD device, a third switch is changed over so that the video signal reproduced at the VTR is output.

    摘要: Disclosed herein are a method and apparatus for industrially freezing (or cooling) food or the like under pressure. The method consists of isostatically exerting pressure on the material such as food (14) and the frozen body (15) composed mainly of water through the pressure medium (12) contained in the pressure vessel (1), thereby cooling the material (14). When the temperature of the material (14) decreases below 0.degree.C. at which freezing does not take place under pressure, the pressure is released rapidly so that fine ice crystals are formed in the material (14). The apparatus comprises a pressure vessel (1) having therein a high-pressure chamber (6) which can be supplied with a pressure medium (8), a treating vessel (9) in said high-pressure chamber (6), said treating vessel (9) having therein a treating compartment (13) containing a pressure medium (12) to apply isostatic pressure, and a plurality of trays (16) removably arranged in the treating compartment (13) in its axial direction, each of said trays holding the material (14) and the frozen body (15) composed mainly of water.
