  • Patent number: 8807383
    Abstract: A gasoline storage device, which is regulated to prevent gasoline from vaporizing, and is fabricated from a soft gasoline bag made from soft material that has been processed and coated on both sides so as to be resistant against gasoline and the majority of chemical liquids. The soft gasoline bag can be folded into a small size, directly disposed into a steel gasoline tank and allowed to unfold. Expandable hoses are used to respectively connect to the existing gasoline inlet pipe, gasoline-measuring pipe and manhole of the steel gasoline tank. The soft properties of the soft gasoline bag are used to isolate the gasoline stored within the steel gasoline tank from the air, thereby reducing vaporization of gasoline, pollution and wastage.

  • Publication number: 20140212240
    Abstract: A fastening assembly includes a fastening screw and a fastening assembly. The fastening screw includes a head section having multiple first tooth elements at a lower surface thereof, and a screw fastening section at a lower portion thereof for fastening into a work piece. The fastening accessory includes multiple second and third tooth elements at upper and lower surfaces thereof, respectively, multiple grooves formed between the second tooth elements, and an embedding recess at an upper portion thereof. The fastening accessory is accommodated at a lower portion of the fastening screw to lodge the first tooth elements into the embedding recess, such that the fastening accessory is closely fastened to the lower portion of the fastening screw. The third tooth elements are engaged to a surface of the work piece to allow both of the fastening screw and the fastening accessory to become closely fastened to the work piece.

  • Publication number: 20140209702
    Abstract: A mist spraying device includes a base having a control circuit and a battery, a water tank having an atomizing plate and a water level sensor, and an upper lid. The top of the base includes metal junctions connected with a power end and a sensor end of the control circuit. The water tank is connected to an upper end of the base, and a bottom of the water tank includes conductor junctions, enabling the control circuit to control the atomizing plate to atomize by oscillation water or liquid in the water tank into water steam or gasified liquid to be sprayed out. The upper lid is assembled with the base, covers the water tank, and includes a spraying hole to spray out water steam or gasified liquid formed by atomizing water or liquid in the water tank by the atomizing plate.

  • Patent number: 7127317
    Abstract: The present invention provides an Intelligent Engineering Data Analysis (I-EDA) system and method to help prevent low wafer yield and prevent occurrences of abnormal events. The I-EDA has a non-conforming wafer tracing (NCWT) system that operates to correlate occurrences of abnormal events with low wafer yield. The method generally has the steps of performing a fabrication operation on wafers disposed within a wafer lot; determining if an abnormal event occurred while performing the fabrication operation on the wafers disposed within the wafer lot; using a NCWT to determine a statistical correlation between an occurrence of an abnormal event and a wafer yield of the wafers being processed during the occurrence of the abnormal event if the abnormal event occurred during processing of the wafers disposed within the wafer lot; and using the determined statistical correlation to analyze the fabrication process and thereby improve wafer yield.
