  • Patent number: 11979095
    Abstract: An object of the present invention is to provide a power conversion device capable of specifying a failure location of an inverter in detail when an attempt of active discharge fails. There are provided an arithmetic operation circuit 102 that outputs a discharge instruction to control a discharge operation based on a voltage between both ends of a discharge circuit, and an output circuit 203 that outputs a drive signal based on the control signal. The arithmetic operation circuit 102 monitors an amount of the decreased voltage between both the ends of the discharge circuit, an LV read back signal being an output of the arithmetic operation circuit 102, and an HV read back signal being an output of the output circuit 203, and specifies a failure location.

  • Patent number: 7610938
    Abstract: A cylindrical rod 20 is formed by bending sheet metal 10 so as to bond together a pair of edges 12 and 14 of the sheet metal 10. The cylindrical rod 20 includes therein (i) convex portions 16 each of which protrudes from the edge 12 and includes a sub-portion whose width is larger at a side thereof more distant from the edge 12 than at a side thereof less distant from the edge 12, and (ii) concave portions 18 which are formed on the edge 14, have a shape complementary to the shape of the convex portions 16, and are fitted into the convex portions 16. A cylindrical rod which has high circularity and high linearity, in other words, which hardly has vertical and horizontal curves can be provided.

  • Publication number: 20070126740
    Abstract: An animation creating apparatus that realizes more expressive “talking animation” by simplifying interface functions of a voiced/silent decision section and animation creating section and providing these sections in independent configurations, and that flexibly support various animation creating schemes and enable portable terminals to have lip-sync animation creating functions. In this apparatus, voiced/silent decision section 102 outputs degrees of voicedness of input speech signal (called “degree of voicedness”) and outputs them to animation creating section 103. Animation creating section 103 stores three images of a closed mouth, half-opened mouth and opened mouth, selects corresponding images from the three images by deciding the degree of voicedness input from voiced/silent decision section 102 with decision criteria in 3 stages of L, M, S, and performing a state transition, creates “talking animation” and outputs it to display section 104.
