  • Publication number: 20240130083
    Abstract: A vapor chamber in which an enclosed space is formed, and a working fluid is sealed in this space, the enclosed space including: a plurality of condensate flow paths through which a fluid that is the working fluid in a condensing state flows; and vapor flow paths through which a vapor that is the working fluid in a vaporizing state flows, wherein each of projecting parts with which each of the vapor flow paths is provided has a projecting amount varying in an extending direction of the vapor flow paths; a pitch for opening parts that allow the vapor flow paths and the condensate flow paths to communicate varies in the extending direction of the vapor flow paths; or wall parts that separate the flow paths each have a given relationship with a transverse cross section of a given flow path.

  • Publication number: 20220220072
    Abstract: The present invention provides a method in which when using (+)-dibenzoyl-D-tartaric acid to optically divide (±)-1-methyl-4-(2,4,6-trimethoxyphenyl)-3-piperidinone, an ether-based solvent is added and an extremely high yield of (R)-1-methyl-4-(2,4,6-trimethoxyphenyl)-3-piperidinone (+)-dibenzoyl-D-tartrate is thereby obtained, a slurry thereof is treated with a base, a “three-dimensionally bulky reducing agent” is subsequently used, and cis-(?)-flocinopiperidol is thereby produced with surprisingly high selectivity.

  • Publication number: 20200131161
    Abstract: It is known that foods containing a carbohydrate, e.g., starch, in a large amount produce acrylamide upon heating at high temperatures. Some documents state that acrylamide is formed by the Maillard reaction of an amino acid, e.g., asparagine, with a reducing sugar. The purpose of the present invention is to provide a novel compound which is effective in inhibiting such foods from yielding acrylamide when treated at a high temperature. Specifically, the present invention provides a compound represented by General Formula (I).
