Publication number: 20110210285Abstract: The present invention relates to maintaining the fundamental physical properties of a liquid alkali metal with dispersed nanoparticles which is such that nanoparticles are uniformly dispersed and mixed in a liquid alkali metal used in heat exchange, cooling and other applications, and suppressing the reaction of the liquid alkali metal with dispersed nanoparticles. Provided is a method of manufacturing a liquid alkali metal with dispersed nanoparticles by dispersing nanoparticles in a liquid alkali metal. In this method, the nanoparticles are made of a metal having a large atomic bonding due to a combination with the liquid alkali metal compared to the atomic bonding of atoms of the liquid alkali metal and a metal having a large amount of charge transfer is used in the nanoparticles. The liquid alkali metal is selected from sodium, lithium and sodium-potassium alloys, and the nanoparticles to be dispersed are made of transition metals, such as titanium, vanadium, chromium, iron, cobalt, nickel and copper.Type: ApplicationFiled: February 2, 2011Publication date: September 1, 2011Inventors: Kuniaki ARA, Junichi Saito, Hiroyuki Sato, Nobuki Oka, Masahiko Nagai, Koichi Fukunaga

Publication number: 20110203504Abstract: A multi-needle sewing machine includes a plurality of needle bars having lower ends to which needles are attached, respectively, a needle bar selecting unit selectively switching one of the needle bars to a needle location, a stitch number obtaining unit and an allotting unit. An embroidery pattern including a plurality of partial patterns is sewn by the use of needle threads of colors differing per partial pattern, while the needle bars are selectively switched. The stitch number obtaining unit obtains the number of stitches necessary for sewing the partial patterns for every partial pattern. The allotting unit allots the needle threads to the needle bars so that the needle bars are prevented from being one-sided in the number of stitches, based on the obtained number of stitches, in order that one of the needle bars to be used for the sewing of each partial pattern may be determined.Type: ApplicationFiled: February 9, 2011Publication date: August 25, 2011Applicant: BROTHER KOGYO KABUSHIKI KAISHAInventors: Masahiko NAGAI, Atsuya HAYAKAWA

Patent number: 7425810Abstract: Arrangements and methods for implementing a “spin-down policy” for HDD motors that is “smart”, flexible and admirably achieves an objective of ensuring prolonged motor life as just discussed. To this end, one specific implementation involves (among other things) the addition of a dedicated cache that acts as a buffer element of sorts for writing or obtaining data during a period when a motor may be spun down, especially (but not necessarily exclusively) in instances when a notebook needs to be running for a large portion of the day. Other analogous implementations are of course possible that would achieve similar ends.Type: GrantFiled: June 30, 2006Date of Patent: September 16, 2008Assignee: Lenovo (Singapore) Pte., Ltd.Inventors: Jeffrey R.
