  • Publication number: 20170103843
    Abstract: Disclosed is a wound iron core (3) for a static apparatus in which magnetic paths in the inside of the wound iron core are subdivided to improve iron core characteristics. The iron core (3) is configured by using two or more kinds of magnetic materials (11 to 14) with different magnetic permeabilities to form laminated blocks with single plates or a plurality of laminated plates and by alternately arranging the laminated blocks with different magnetic permeabilities from the inner circumference. An iron core material (14) with large magnetic permeability out of iron core materials with different magnetic permeabilities is arranged on the inner circumference side. Further, when the iron core materials with different magnetic permeabilities are alternately arranged, the iron core materials (11) with the same magnetic permeability are configured to gradually change in thickness to ease an excessive magnetic flux density distribution in the iron core.

  • Patent number: 9617945
    Abstract: A control device of a spark-ignition engine is provided. The control device includes a main body of the engine, a fuel injection valve, an ignition plug, and a controller. According to an engine operating state, the controller switches between a compression-ignition mode in which compression-ignition combustion is performed, and a spark-ignition mode in which spark-ignition combustion is performed. The controller switches from the spark-ignition mode to the compression-ignition mode by performing in order, a first stage where an air-fuel ratio of mixture gas is set to a predetermined value and the spark-ignition combustion is performed, a second stage where the air-fuel ratio of the mixture gas is set leaner than the first stage and the compression-ignition combustion is performed, and a third stage where the air-fuel ratio of the mixture gas is set richer than the second stage and the compression-ignition combustion is performed.

  • Patent number: 9514877
    Abstract: During the assembly process of an amorphous core transformer, when an offset has arisen between a coil and the amorphous core, and when an offset has arisen between the coil and the core due to a shock resulting from unloading or vibrations during transport, there has been the risk of breakage of an insulating member between an amorphous core and a coil, causing amorphous fragments to be scattered. The object of the present invention is to prevent scattering of amorphous fragments.

  • Publication number: 20160214809
    Abstract: When a paper feeding ray is set, an arm of a one-armed pinion makes a contact with an abutting member formed in a main unit to which the paper feeding tray is attached. When the paper feeding tray is pushed in, the arm is pushed by the abutting member, the one-armed pinion rotates as the rack member moves, and the one-armed pinion moves in a direction into the paper feeding tray. When a spring is stretched, a bottom plate push-up member rotates up on its rotation center and rises by a predetermined angle to press a bundle of stacked paper sheets against a feed roller, so that the paper sheets can be fed.
