  • Publication number: 20240141471
    Abstract: A method of forming an Al—Zn—Si—Mg alloy coating on a steel strip includes dipping steel strip into a bath of molten Al—Zn—Si—Mg alloy and forming a coating of the alloy on exposed surfaces of the steel strip. The method also includes controlling conditions in the molten coating bath and downstream of the coating bath so that there is a uniform Al/Zn ratio across the surface of the coating formed on the steel strip. An Al—Zn—Mg—Si coated steel strip includes a uniform Al/Zn ratio on the surface or the outermost 1-2 ?m of the Al—Zn—Si—Mg alloy coating.

  • Patent number: 9822387
    Abstract: An acetyl-CoA-producing microorganism, which is capable of efficiently synthesizing acetyl-CoA using carbon dioxide, and a substance production method using the same are provided. An acetyl-CoA-producing microorganism including an acetyl-CoA production cycle obtained by imparting at least one type of enzymatic activity selected from the group consisting of malate thiokinase, malyl-CoA lyase, glyoxylate carboligase, 2-hydroxy-3-oxopropionate reductase, and hydroxypyruvate reductase, to a microorganism.

  • Patent number: 9267156
    Abstract: An isopropyl alcohol-producing Escherichia coli includes an isopropyl alcohol production system, wherein an activity of transcriptional repressor GntR is inactivated, and the isopropyl alcohol-producing Escherichia coli preferably further includes a group of auxiliary enzymes having an enzyme activity expression pattern with which isopropyl alcohol production capacity achieved by the inactivation of the GntR activity is maintained or enhanced. A method of producing isopropyl alcohol includes producing isopropyl alcohol from a plant-derived raw material using the isopropyl alcohol-producing Escherichia coli. A method of producing acetone includes contacting the isopropyl alcohol obtained by the isopropyl alcohol production method with a complex oxide that includes zinc oxide and at least one oxide containing a Group 4 element, and that is prepared by coprecipitation.

  • Patent number: 6992721
    Abstract: The present invention aims at providing a function-expansion unit for an electronic apparatus that may reduce the stress onto a connector, and provides a high stability with a CCD camera. The CCD camera includes a reinforcing member under its connecting portion and a height-adjustable stand, thereby reducing the stress that would otherwise apply to the USB connector as the connecting portion, enhancing the connection, preventing connector's deterioration in the course of time, and allowing the CCD camera to be stably placed.

  • Patent number: 6804827
    Abstract: An object of the present invention is to provide a multi-channel transmission system suitable for a digital broadcasting system that broadcasts television programs of many channels. Specifically, a selected one of television programs of a plurality of channels is supplied to an AV adjusting device. At this time, the selected television program is supplied to a monitor to allow recognition of its adjustment state. Since video signals and audio signals of television programs supplied from respective program supplying companies and program producing companies have different characteristics, they need to be adjusted to have common characteristics. Adjusted television programs and unselected television programs are supplied to a multiplexing section via routers.
