  • Publication number: 20220349026
    Abstract: A metal purifying method having: a local heating step of heating an aluminum-based molten metal in a first region on a molten metal surface of the aluminum-based molten metal; and a local low pressure step of lowering the pressure in a second region on the molten metal surface to a pressure lower than the pressure in the first region. The second region is different from the first region. This allows a specific element to be vaporized from the second region to purify the aluminum-based molten metal. The specific element is one or more of Zn, Mg, or Pb having a saturated vapor pressure higher than that of Al. This is effective not only in a purifying method for removing a specific element from an aluminum-based molten metal but also in a method of recovering a specific element, which can be a resource, from an aluminum-based molten metal.

  • Publication number: 20220029819
    Abstract: SSL is improved with stronger defense against an attack from a third party, in particular, an MITMA. A client and a server each have the function of generating the same solution under the same conditions. The client generates a first solution (S1002) and transmits the solution to the server (S1003). When receiving the solution, the server generates a solution (S2002) and authenticates the client if the solution agrees with the solution received from the client (S2003). The server generates a new solution (S2004), encrypts a server certificate and an SSL certificate (S2005) by using the solution, and then transmits the certificates to the client (S2006). The client generates a new solution (S1005) and decrypts the server certificate and the SSL certificate by using the solution (S1006). The subsequent processing is identical to that of current SSL communications.

  • Patent number: 5765767
    Abstract: A double screen (42) including a cylindrical screen (18) and a conical screen (23) is attached to an upper casing (3) into which a revolution shaft (11) is inserted and is provided with a supply opening (2). A rotary blade 12 is arranged within an annular space (15) having a nearly V-shaped section between the cylindrical screen (18) and the conical screen (23) so as to rotate keeping a desired gap relative to the respective screen surfaces. Since the annular space (15) having the nearly V-shaped section is spaced apart from the revolution shaft (11), the rotary blade (12) rotates at a high circumferential speed even in the bottom portion of the annular space (15).

  • Patent number: 4672651
    Abstract: An object is irradiated with respective cone-beam like X-rays from first and second directions. For each of the first and second directions are produced mask and live images as respective projection images of the object before and after a contrast medium reaches an interested part of the object. Then, subtraction of the mask image from the live image is made in conjunction with each of the first and second directions. The resulting subtraction image assumes a projection image of the distribution of the contrast medium in the interested part taken in the corresponding direction. The respective projection widths of such projection images of the contrast medium distribution are determined to generate an ellipse defined by the projection widths. The shape of this ellipse is corrected in accordance with individual data values in the projection images of the contrast medium, thereby providing a corrected shape accurately resembling the actual shape of the interested part of the object.
