  • Patent number: 7778011
    Abstract: A chip type solid electrolytic capacitor includes a capacitor element-laminate. In the capacitor element-laminate, a plurality of capacitor elements, each having an anode portion and a cathode portion, are laminated so that the anode portions of the adjacent capacitor elements are disposed in the direction opposite to each other. Anode lead terminals are joined to the bottom faces of the anode portions of the capacitor elements disposed at both ends of the capacitor element-laminate. A cathode lead terminal is joined to the bottom face of the cathode portion of the capacitor element disposed in the center of the capacitor element-laminate. An Electrically insulating exterior resin coats the capacitor element-laminate so as to expose at least a part of the bottom faces of the anode lead terminals and a part of the cathode lead terminal.

  • Patent number: 7770556
    Abstract: Improvement of combustion stability in retard ignition at the time of starting in a cold state, high output in a full throttle condition, reduction of smoke, and prevention of wear of the cylinder liner caused by oil dilution, are to be attained. In connection with the flow of fuel into each hole and a fuel inflow angle which is determined by the axis of each hole formed in a plate, the fuel inflow angle of an hole directed to a spark plug is set large to reduce an effective flow path area, thereby making the amount of fuel in the hole smaller than in other holes. A shallow cavity is formed in a piston crown face and a small prominence confronting fuel sprays is formed within the cavity.

  • Patent number: 7642869
    Abstract: A clock generator includes a ring oscillator for outputting a basic signal, a divide-by-N frequency divider for dividing the basic signal by a division ratio N to generate a clock signal having a target frequency, a divide-by-two frequency divider for dividing the clock signal by two when an enable signal is on, a counter for counting the number of pulses of the basic signal for a predetermined period of time, a calculator for calculating the division ratio N, and a comparator for comparing a count value of the counter with a threshold value. When the count value of the counter is less than the threshold value, the comparator turns on the enable signal. Thus, when a temperature of the ring oscillator increases, the frequency of the clock signal is reduced to half the target frequency.
