  • Patent number: 7226354
    Abstract: A cabinet wherein air sucked from an inlet opening 4d of a shelf board combined inlet duct 4 by drive of an air purification unit 3 is passed through the shelf board combined inlet duct 4 and introduced into the inside of a case 3a, and by a dust collection filter 32 and an odor eliminating means 33. Air forced into the shelf board combined outlet duct 5 through the air duct 10 is exhausted through an outlet opening 5d of the shelf board combined outlet duct 5, and air curtain is formed along the opening of the storage section 11 of a cabinet 1. Therefore, air in the storage section 11 of the cabinet 1 is circulated and purified, while getting caught in a circulating airflow including the air curtain.

  • Patent number: 7101277
    Abstract: A cabin pressure control system and method extends the cabin pressure control logic beyond the original maximum certified altitude of the aircraft, without having to update the control logic. Thus, the control system provides an independent means of limiting cabin-to-atmosphere differential pressure above the original maximum certified altitude if the aircraft exceeds, or is re-certified to exceed, its original maximum certified altitude.

  • Patent number: 7097804
    Abstract: A duct formed of a thermoplastic material is lightweight, strong, flame and smoke resistant, and non-toxic. The duct is formed from a flat laminate and does not require a specialized, disposable mandrel for supporting conventional thermoset plies. Preferably, the duct is formed from a preform, which is cut according to the desired shape and size of the duct so that trimming after the duct has been formed is not required. Additionally, features such as holes and spud locations can be provided by cutting or marking the preform before forming the duct. Each duct can be formed of multiple articulated segments that are joined by connectors.

  • Patent number: 7025671
    Abstract: A surface mounted device includes a hollowed base body mounted on a building or vehicle exterior, and a hollowed raised body supported and secured on the base body with hollowed elongated members. A free space is formed between the base body and the raised body. An opening or openings are facilitated on, and near the center of, the lower surface of the raised body, to connect the free space with the internal space of the base body through the hollowed raised body and hollowed elongated support members. The base body and the raised body are configured in such a way that the free space between them is narrower at the center than along the perimeter. This forms an airflow path that is first contracting towards the center and then expanding afterwards for any approaching wind direction, providing a venturi mechanism.

  • Patent number: 7022009
    Abstract: A cleaning system for n semiconductor manufacturing equipment includes a working area and a service area. A wafer process area in the service area performs a semiconductor manufacturing process. A wafer transfer area is spatially connected to the wafer process area, and transfers a wafer from the working area to the wafer process area. An air supply device supplies clean air to the wafer transfer area and the wafer process area. A particle measurer continuously checks for any malfunction or defect of the air supply device, and measures in real time an impurity particle count of the air in the wafer transfer area so as to detect any abnormally high pollution level in the wafer transfer area.
