    摘要: The apparatus of the invention is an injection molding apparatus of a type adapted to cool a molten metal under shearing by an extrusion screw in a substantially vertical chamber into a semi-solidified slurry and then inject the semi-solidified slurry discharged from a discharge port at the lower end of a channel into molding plates, in which a clamping device is adapted to open or close a movable plate relative to a stationary plate in the horizontal direction, and a connection member having, at the inside, a vertical first channel and a second channel extending in the horizontal direction from the lower end of the first channel and in communication with the stationary plate is connected to the discharge port at the lower end of the chamber. Since this can inject and mold light metal molding products of high quality with less pore or shrinkage without excessively enlarging the size for the height of the apparatus, casting products of high quality can be obtained at a reduced cost by injection molding.

    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.
