    摘要: A controller K calculates a command torque by correcting the required torque w1 with a correction based on a motor rotation speed Nm, and controls an electric motor based on the command torque T. The command torque w1 is regarded as one content of an outside input W to the controller K. A difference between the rotation speed of the electric motor outputted by the actual model describing an actual response of the electric motor and another rotation speed of the electric motor outputted by a reference model describing ideal performance and vibration reduction is regarded as one content Z1 of controlled output Z from the controller K. Moreover, a characteristic variation depending on vehicle types and so on, a torque ripple, and a sensor noise are described by weight functions wm1, wm2 and wn. Then a pertubative output w2 and a sensor noise w3 are regarded as the remaining contents of the input W. An output of the weight function wm2 is regarded as the controlled output Z. The controller K is determined by solving H∞control problem that a transfer function between the outside input W and the controlled output Z is determined as an H∞norm of the transfer function to be smaller than a predetermined value.

    摘要: An object of the present invention is to provide a printed wiring board which does not require arranging signal lines oblique to the warp or weft threads constituting a substrate and is capable of reducing a difference in transmission rates between the signal lines. The present invention relates to a printed wiring board including: an insulating layer; and a signal layer including a set of at least two signal lines and disposed on one side of the insulating layer. A substrate is embedded inside the insulating layer in such a manner to be further from the signal layer than a center of the insulating layer in a thickness direction of the insulating layer is. The insulating layer has a laminated structure of a thick layer, the substrate, and a thin layer. A ratio of a thickness of the thick layer to a thickness of the thin layer is greater than five.

    摘要: An electric pump for supplying a hydrogen gas to a fuel cell includes a rotary shaft rotatably inserted through an electric motor, a transmitting member provided on one of an outer peripheral surface of the rotary shaft and an inner peripheral surface of the electric motor so as to be rotatable therewith, and a groove formed in the other of the outer peripheral surface of the rotary shaft and the inner peripheral surface of the electric motor for the transmitting member to be inserted therein. The groove transmits a rotary torque of the electric motor to the rotary shaft by contacting an inner surface of the groove and the transmitting member and has an opening width along a rotary direction of the rotary shaft which is larger than the width of the transmitting member. The groove and the transmitting member produce an impact torque when the electric pump is started.
