    摘要： A method and an apparatus (10) for making thin layers from particles, wherein the particles are deposited on a carrier fluid flowing by gravity along a ramp (12) leading to a dam (18). The particles are held back at the bottom of the ramp (12), thereby causing the particles to be piled up one against the other in a monolayer configuration.

    摘要： A magnetic recording tape exhibits reduced magnetic flux modulation and improved signal-to-noise ratio. Providing a magnetic recording layer with a more uniform thickness can improve the magnetic flux modulation characteristic. For example, the magnetic recording tape may have a coercivity of greater than or equal to 2000 Oe with a magnetic flux modulation characteristic having a one sigma standard deviation of less than 0.06. In some cases, the magnetic flux modulation characteristic may have a one sigma standard deviation of less than 0.05, or even 0.04. Reduced magnetic flux modulation can support increased storage densities.

    摘要： The present invention provides a method for removing wrinkles formed on a web, which is continuously transported through a plurality of guide members. The plurality of guide member includes a crown roller which has the diameter gradually increased toward the center thereof. The crown roller is placed in a transport path of the web and downstream of a first zone in which wrinkles are desirably removed, and the web is deformed in a second zone located downstream of the crown roller so as to at least decrease the width of the web, whereby the wrinkles in the first zone are removed. Even when the web is thin (10 μm or less), without using particular backup means, wrinkles formed during transport and coating of the web can be removed. In addition, since wrinkles are appropriately removed, a coating film having a uniform thickness can be obtained by an extrusion coating method.

    摘要： The coating apparatus and method enable the coating liquid having been scraped-off to be reused without doing any one of the fluid adjusting treatment and the filtering treatment, while maintaining the features of the scraping-off type of extrusion coater, which is suitable for obtaining a uniform and extremely thin coating film. The coating head is provided with two slits: a coating slit and a recovering slit, and the excessive coating liquid having been discharged through the coating slit and applied to the web is scraped-off and recovered through the recovering slit.
