  • Enclosed compressor and cooling system
    Patent number: 6155067
    Abstract: A hermetic compressor of the present invention is provided with one or more small holes 17 formed in the shell of the suction muffler 16 formed with a low thermal conductivity material such as synthetic resin. The small holes 17 are positioned at nodes 18 in a vibration mode for the resonance frequency of the space formed in the hermetic shell, so that amplification of the resonance sound of the space in the hermetic shell 1 is suppressed. Furthermore, a shortage of the refrigerant is supplemented by the refrigerant gas sucked from the hermetic shell 1 through the small holes 17 when it occurs due to a suction loss caused by the resistance of the flow path for guiding a high density refrigerant gas from the suction tube into the cylinder 8 according to the circulation of the refrigerant.

  • Data processor
    Patent number: 5406273
    Abstract: A data processing apparatus receives key codes corresponding to keys depressed on a plurality of keyboards. These key codes are sequentially stored in a first-in first-out (FIFO) buffer awaiting processing by a central processing unit (CPU). If successive key code entries correspond to an auto repeat key (e.g., a space key, a backspace key, an underline key, a move cursor key, etc.), a determination is made whether the auto repeat key codes are the same. If they are, the CPU processes the subsequent auto repeat key code. If they are different, the CPU ignores that auto repeat key input. In another embodiment of the present invention, one of the keyboards is hardwired to the data processing system while a second keyboard is connected via a wireless link. Auto repeat key codes are only accepted from the first wire-connected keyboard, and any auto repeat key codes from the second wireless keyboard are ignored.

  • Data processor with wireless auxiliary input apparatus
    Patent number: 5307297
    Abstract: In a data processor having a box type unit in which a keyboard and a folding display are incorporated, the data processor includes a main unit which has a receiver for wireless signals on an external side wall close to a supporter for pivotally supporting the folding display, and an auxiliary input apparatus having a case unit and a wireless signal transmitting unit at a corner of said case unit which is opposed to the receiving unit of said main unit when juxtaposed with said keyboard.
