  • Publication number: 20210175742
    Abstract: In an uninterruptible power supply apparatus, in a power failure of a commercial AC power supply, a switch is turned off to electrically cut off the commercial AC power supply from an AC input filter, and a DC voltage converter is controlled such that a DC voltage that is the difference between terminal-to-terminal voltages of first and second capacitors is eliminated, and when the DC voltage exceeds a threshold voltage, a converter is controlled to reduce the DC voltage.

  • Publication number: 20200235655
    Abstract: In this uninterruptible power supply apparatus, respective phase differences between first to third carrier wave signals (CS1 to CS3) for a converter (1) and fourth to sixth carrier wave signals (CS4 to CS6) for an inverter (2) are set to 180 degrees in an inverter power feed mode and a bypass power feed mode, and respective phase differences between the first to third carrier wave signals and the fourth to sixth carrier wave signals are set to 0 degree in an overlap power feed mode. Zero-phase current (I01, I02) and circulating current (ICL) therefore can be reduced.

  • Patent number: 8874289
    Abstract: An apparatus, applied to a vehicle having an internal combustion engine and an electric motor as power sources, comprises a changeover mechanism which is able to change a connection state of an electric motor output shaft to any one of “an IN-Connection State” in which a power transmission path is provided between a transmission input shaft and the electric motor output shaft, “an OUT-Connection State” in which a power transmission path is provided between the transmission output shaft and the electric motor output shaft, and “a neutral state” in which no transmission path therebetween is provided. When a changeover condition is satisfied, a period is provided in which a sum Ts of an internal-combustion-engine-side-output-torque Te and an electric-motor-side-output-torque Tm coincides with a required driving torque Tr, and an electric motor torque continues to be zero.

  • Patent number: 8718518
    Abstract: A development roll for electrophotographic equipment includes a shaft body, a rubber elastic layer formed by molding on an outer circumference of the shaft body and having many convex portions formed by transfer molding on the outer circumferential surface thereof, and a coating layer disposed on an outer circumference of the rubber elastic layer. The coating layer is composed of a cured body of a coating material containing (A) a thermoplastic urethane having a number-average molecular weight in the range of 50,000 to 200,000, (B) a polyol having a number-average molecular weight in the range of 500 to 4,000, and (C) a curing agent. The mass percentages a, b, and c of the components (A), (B), and (C) satisfy the following expressions: a+b+c=100, 40?a?75, 5?b?20, and 20?c.

  • Patent number: 8545365
    Abstract: An apparatus comprises a changeover mechanism which is able to change a connection state of an electric motor output shaft to any one from alternatives consisting of “an IN-Connection State” in which a power transmission path is provided between a transmission input shaft and the electric motor output shaft, “an OUT-Connection State” in which a power transmission path is provided between the transmission output shaft and the electric motor output shaft, and “a neutral connection state” in which no transmission path therebetween is provided. The changeover is carried out based on a combination (area) of a vehicle speed V and a required driving torque T. As for the changeover, an (first, second) IN-connection area is more enlarged and the OUT-Connection area and the neutral connection area are more narrowed, as a temperature of a lubricating oil is lower.

  • Patent number: 8480535
    Abstract: A hybrid-type power transmission in which an internal combustion engine and an electric rotating machine are used as a source of power for driving an output shaft through a change-speed mechanism. In the hybrid power transmission, the operation of the electric rotating machine is controlled in such a manner that the rotation speed of a rotor-side rotary member is synchronized with the rotation speed of an input-side or output-side rotary member when the rotation speed of the rotor-side rotary member becomes higher in a predetermined difference than the rotation speed of the input-side or output-side rotary member in shifting operation of a sleeve coupled with the rotor-side rotary member.

  • Patent number: 8388496
    Abstract: An apparatus comprises a changeover mechanism which is able to change a connection state of an electric motor output shaft to any one from alternatives consisting of “an IN-Connection State” in which a power transmission path is provided between a transmission input shaft and the electric motor output shaft, “an OUT-Connection State” in which a power transmission path is provided between the transmission output shaft and the electric motor output shaft, and “a neutral state” in which no transmission path therebetween is provided. The changeover is carried out based on a combination (area) of a vehicle speed V and a required driving torque T. As for the changeover, a neutral area is enlarged so that a possibility of selecting the neutral state becomes higher, as a battery temperature is higher, or as an electric motor temperature is higher, or as a remaining battery level is larger.

When a kick-down-condition is satisfied, a changeover operation for changing an electric motor connection state to the OUT-Connection State is firstly performed. Thereafter, a gear position shifting operation for increasing a transmission reduction ratio is performed. After the kick-down-condition satisfied, an E/G side output torque Te and a M/G side output torque Tm is adjusted in such a manner that a sum Ts of Te and Tm continues to increase.
