  • Patent number: 8310802
    Abstract: A metallization film capacitor that achieves both high heat resistance and high withstand voltage at the same time. A metal-deposited electrode is formed on a PEN film in each of a pair of metalized films. These metalized films are wound such that the metal-deposited electrodes face each other via the dielectric film in between. A metalized contact electrode is formed on both end faces of these wound metalized films to configure the metallization film capacitor. A divisional electrode is provided on the metal-deposited electrode. In addition, a fuse is coupled to this divisional electrode for providing a self-maintaining function. Pass rate a/b of a deposition pattern is set to 4.0 or smaller, where ‘a’ is the fuse width, and ‘b’ is the length of the divisional electrode in a lengthwise direction of the metalized films.

  • Publication number: 20120108013
    Abstract: In QFN packages for vehicles which are required to have high reliability, the side surface of leads is mostly covered with lead-to-lead resin protrusions, which prevent smooth formation of solder fillets during reflow mounting. When the lead-to-lead protrusions are mechanically removed using a punching die, there is a high possibility of causing cracks of the main body of the package or terminal deformation. When a spacing is provided between the punching die and the main body of the package in order to avoid such damages, a resin residue is produced to hinder complete removal of this lead-to-lead resin protrusion. The present invention provides a method for manufacturing semiconductor device of a QFN type package using multiple leadframes having a dam bar for tying external end portions of a plurality of leads.

  • Publication number: 20110260683
    Abstract: A vehicle charging apparatus includes: an electric generator 3 that is driven by an internal combustion engine 1 and outputs an adjustable alternating-current voltage; a rectifier 4 that converts the outputted alternating-current voltage to a direct-current voltage; an electric storage device 5 that is charged with the converted direct-current voltage; and a voltage sensor 6 that measures an output voltage of the rectifier 4. The vehicle charging apparatus is provided with a control device 7 that controls the electric generator 3 for a charging voltage to be a target charging voltage calculated from the output voltage in order to suppress a charging current to be lower than a charging current upper limit value when the electric storage device 5 is charged. It thus becomes possible to achieve efficiency higher than that of a charging apparatus in the related art while preventing deterioration or damage of the electric storage device.

  • Patent number: 7983832
    Abstract: An object of the present invention is to provide a fuel injection control technique which maximizes engine power according to fuel evaporation characteristics. The fuel injection timing in the intake stroke is delayed according as a physical quantity affecting the fuel evaporation time changes such that the fuel evaporation time decreases. Further, the fuel injection timing when a physical quantity affecting the fuel evaporation time is such that the fuel evaporation time decreases is set closer to the end of the intake stroke than the fuel injection timing when the physical quantity is such that the fuel evaporation time increases. The fuel injection timing is controlled so as to maximize engine power according to fuel evaporation times.
