  • Patent number: 11946470
    Abstract: An information processing apparatus detecting presence or absence of abnormality of a vacuum pump derived from a product produced within a target vacuum pump, including: a determination unit configured to determine a normal variation range or a normal time variation behavior of a target state quantity which is a state quantity varying depending on a load of gas flowing into the vacuum pump, based on at least one of past target state quantities of the target vacuum pump or another vacuum pump; and a comparison unit configured to compare a current target state quantity of the target vacuum pump with the normal variation range or the normal time variation behavior and output the comparison result.
    Type: Grant
    Filed: March 13, 2018
    Date of Patent: April 2, 2024

  • Patent number: 5428503
    Abstract: A cooling apparatus for electronic equipment for improving the reliability of the equipment by making uniform the temperature distribution of heat generating devices mounted on the electronic equipment, more particularly on a computer and for reducing the working process required at the time of performing a maintenance of a printed circuit board in the electronic equipment by stacking, in a frame, the electronic printed circuit boards on which the heat generating devices, such as a CPU and memories, are mounted at predetermined intervals. The cooling apparatus has a fan fastened to one wall surface of a chamber and a plurality of jet cooling devices formed on the surface opposing the wall surface. The jet cooling devices are formed in parallel to the printed circuit boards. The jet cooling devices are slits, or nozzles or jet stream ducts extending among the printed circuit boards and are so formed as to supply cooling air in a jet stream state to each heat generating device.
