  • Publication number: 20240123943
    Abstract: A motor control device includes a driving control part and an upper limit value setting part. The driving control part controls motor driving by switching between a first driving mode and a second driving mode, and controls an output duty ratio so as not to exceed a duty ratio upper limit value. The upper limit value setting part sets, as the duty ratio upper limit value, a low rotation duty ratio upper limit value, a maximum duty ratio upper limit value corresponding to a maximum output value, and an upper limit value of a transition period from the low rotation duty ratio upper limit value to the maximum duty ratio upper limit value, and changes slope information indicating a change amount in the upper limit value of the transition period according to the driving mode when switching between the first driving mode and the second driving mode.

  • Publication number: 20240106377
    Abstract: A motor control device which controls a motor having an output shaft includes a vehicle speed detection part and a driving control part. The vehicle speed detection part detects a vehicle speed, which is a traveling speed of a vehicle mounted with the motor. Based on the vehicle speed detected by the vehicle speed detection part, the driving control part performs control of switching between a first driving mode which drives the motor, and a second driving mode in which a number of revolutions of the output shaft and an output of the motor are higher than in the first driving mode.

  • Publication number: 20050069743
    Abstract: A stacked fuel cell comprises a plurality of cell films and a plurality of separators stacked alternately. The cell films each comprise a solid polymer electrolyte film sandwiched between electrode films made of graphite, while the separators are electrically conductive graphite separators each having a fuel gas channel formed in one surface thereof, and an oxidant gas channel formed in the other surface thereof. In the stacked fuel cell, a plurality of partition plates are interposed with predetermined spacing in the direction of stacking. The partition plates each have an electrically conductive graphite terminal board having a groove formed as a piercing portion, through which a band-shaped fastener made of resin (for example, polypropylene) is passed in a direction perpendicular to the direction of stacking, and an electrically conductive graphite end separator having a gas channel formed in a surface thereof in contact with the cell film.

  • Patent number: 6226775
    Abstract: At the time of the preparation of the core macro, the empty interconnection area extraction on the core macro is carried out and the fixed passage in the core macro is prepared by using the empty interconnection area. At the time of the chip layout, the interconnection is provided by using the interconnection for the fixed passage in the core macro. Also, at the time of the preparation of the core macro, the fixed passage interconnection in the core macro is set either in the VDD potential or in the GND potential to prepare the delay library of the core macro.

  • Patent number: 5151248
    Abstract: An austenitic stainless steel for use for high temperature concentrated sulfuric acid which comprises, on weight basis, 0.04% or less of C, 5-7% of Si, 2% or less of Mn, 15-25% of Cr, 4-24% of Ni, 0.01-1.07% of Pd and the rest consisting of Fe and unavoidable contaminant materials. By the incorporation of small amount of palladium in a basal austenitic stainless steel containing the essential three elements of Cr, Ni and Si, a superior corrosion resistance against highly concentrated high temperature sulfuric acid is attained.
