  • Patent number: 6335345
    Abstract: Spiro compounds of the general formula (I): wherein Ar1 represents an optionally substituted aryl or heteroaryl; n represents 0 or 1; T, U, V and W each represent a nitrogen atom or an optionally substituted methine group, wherein at least two of which represent said methine group; X represents methine; Y represents an optionally substituted imino or oxygen atom. These novel spiro compounds exhibit neuropeptide Y receptor (NPY) antagonistic activities and are useful as agents for the treatment of various diseases related to NPY, for example, cardiovascular disorders, central nervous system disorders, metobolic diseases and the like.

  • Patent number: 6162067
    Abstract: A coil bobbin for an AC adapter provides two flanges to be formed at both ends thereof, having coils wound between these flanges, and an incorporated core. At a lower portion of one flange, a unit to fit a rectifying circuit configured by electronic components is provided. A mounting apparatus is configured so that it is selectable whether electronic components are directly attached to a lower portion of a flange, or a substrate on which electronic components are mounted is attached.

  • Patent number: 6008712
    Abstract: A transformer with a modified cover and terminal portion of the coil bobbin to increase the creepage path between a terminal and a core, thus enhancing insulation performance. The invention discloses a cover on a coil bobbin, and includes a groove for increasing a creepage path which is formed in the high voltage side of a coil bobbin terminal portion with an embedded terminal. A projecting insulation wall which is inserted into the groove is formed inside the cover. A bent portion of the terminal is positioned on a lower side of the insulation wall. The transformer core is positioned on the upper side of the projecting insulation wall so as to improve the insulation performance and to allow for reducing or miniaturizing the height between the core and the bent portion of the terminal.
