    摘要: [Task] In a power conversion system, a variation in PCS alternating current voltage is suppressed during a change operation to a self-contained run according to an instantaneous voltage drop-service interruption.[Means for solving the task] During an ordinary system voltage stabilization, with change switch 25 changed to the output side of APR control circuit 22 and change switch 400 changed to the output side of charge/discharge run PWM command value preparing section 200, the power conversion system is run in a charge/discharge run mode. If the instantaneous voltage drop or the service interruption occurs, change switch 25 is changed to the output side of the self-contained run change prior current command value preparing section 60 and the constant current discharge run is carried out in which the electric power is discharged for a predetermined time duration in response to the current command value of the self-contained run change prior current command value preparing section 60. Thus, after a predetermined time has elapsed, change switch 400 is changed to the output side of the self-contained run PWM command value preparing section 30 to perform the self-contained run. At this time, the variation in PCS alternating current voltage in the power conversion system is suppressed.

    摘要: The device includes a rolling bearing unit supporting a radial load and a magnetic bearing unit supporting an axial load and/or a bearing preload; an electromagnet fitted to a spindle housing so as to confront, on a non-contact basis, a flange shaped thrust plate mounted on a main shaft; a motor rotor of a motor for driving the shaft, and a motor stator opposed to the rotor, the shaft being driven by magnetic or Lorentz forces developed between the rotor and the stator; and a sensor detecting an axial force acting on the bearing unit, and a controller controlling the electromagnet. In this device, the stiffness of a composite spring formed by the bearing unit and a support system for the bearing unit is chosen to be higher than the negative stiffness of a composite spring of a motor part comprised of the electromagnet and the motor.

    摘要: When an user inserts already used paper into a shredder of PC, a scanner disposed with the shredder reads a background pattern put on the paper. The shredder shreds and discards the inserted paper. The PC transmits the background pattern put on the discard paper to a background management unit and further notifies a background management unit that the paper is discarded. The background management unit places the background pattern sent from the PC in an unused state and manages the background pattern so that the background pattern can be reused.

    摘要: A polypropylene based nonwoven fabric is excellent in surface appearance and stretch properties and exhibits a small residual strain and excellent adhesiveness to polyolefins. The nonwoven fabric is obtained by forming a polypropylene resin composition comprising 1 to 40 weight parts of (i) an isotactic polypropylene, and 60 to 99 weight parts of (ii) a propylene/ethylene/α-olefin copolymer obtained by copolymerizing 45 to 89 mole % of propylene, 10 to 25 mole % of ethylene and the balance of α-olefin having 4 to 20 carbon atoms (with the proviso that the copolymerized amount of the α-olefin having 4 to 20 carbon atoms does not exceed 30 mole %), characterized by a small residual strain after stretching at a stretch ratio of 150%. The nonwoven fabric can be effectively used as sanitary materials or the like by virtue of its characteristics including stretch properties.
