Publication number: 20020073251Abstract: A data transfer device which set an address of page as transfer destination and transfer data to the page. In the data transfer device to which the present invention is applied, an address and page length of a page are acquired on the basis of an address of a page table specified by a read command. Then, transfer information including the address of transfer source, transfer data length and address of transfer destination of data is set according to page element of page as transfer destination page. Then, it is judged whether the transfer destination page and other page form a continuous area. And if it is judged that the continuous area is formed, transfer information will be changed. Data transfer is effected on the basis of changed transfer information. That reduces the need to set the other area at the transfer destination and thus the transfer efficiency improves.Type: ApplicationFiled: November 21, 2001Publication date: June 13, 2002Inventors: Youichi Yamamoto, Yoshihiro Tabira, Isamu Ishimura

Patent number: 6086671Abstract: A method for melting a silicon starting material can suppress silica (SiO2) from melting out from a quartz crucible wherein the silicon starting material is melted and can provide a high-quality silicon single crystal in a high yield. The growth method comprises melting the silicon starting material charged in the crucible while applying thereto a static magnetic field, contacting a seed crystal to a surface of the silicon melt, and pulling the seed crystal upwardly to solidify the contacted melt. The silicon starting material charged in the crucible, which is under melting, is applied with a static magnetic field such as a Cusp magnetic field, a horizontal magnetic field and/or a vertical magnetic field. The application can control heat convection occurring in the crucible during the course of the melting of the starting material, thereby obtaining a silicon single crystal having a reduced number of dislocation defects.Type: GrantFiled: September 1, 1998Date of Patent: July 11, 2000Assignee: Sumitomo Sitix CorporationInventors: Souroku Kawanishi, Youichi Yamamoto
