    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： Provided is a valve timing adjustment system having improved control for achieving a target rotational phase. The valve timing adjustment system includes: a displacement mechanism unit that displaces a rotational phase of a camshaft relative to a crankshaft of an internal combustion engine; a locking mechanism unit that locks the rotational phase at an intermediate locked phase positioned within a displacement range of the rotational phase; a hydraulic pathway that hydraulically drives the displacement mechanism unit and the locking mechanism unit; and a control unit including a control system that controls operations of the hydraulic control valve. The control unit changes a temporal responsiveness of the control system based on a displacement force that displaces the rotational phase.

A rotation sensor 15 is disposed eccentrically with respect to the rotating shaft 10a in a radial direction of the rotating shaft 10a. The rotation sensor 15 is disposed in a direction in which the rotating shaft 10a is separated from the rotation sensor 15 by a large load F applied from a seatbelt to the spool 10 in an emergency. The rotation sensor 15 includes annularly arranged magnets 21 and a magnet holding member 22 that holds the magnets 21. The magnet holding member 22 includes a receiving gear 23. External teeth 23a of the receiving gear 23 engage with external teeth 24a of the transmitting gear 24 to increase a speed of rotation of the spool 10, whose rotation is transmitted to the receiving gear 23.

    摘要： Lock mechanisms are provide between a first case part and a second case part, which are openable and closable. Projections are formed on an outer side surface of the first case part. Each projection has a stopper hole that extends along a circumferential direction of the outer side surfaces of the case parts. U-shaped deformable pieces are formed with the outer side surface of the second case part and each deformable piece can be deformed in a direction perpendicular to the outer side surface of the second case part. A hook portion is formed with a distal portion of each deformable piece. Guide portions are formed at an edge of an entrance of the stopper hole and guide the hook portion toward the stopper hole. Holding portions are formed at an edge of an exit of the stopper hole and hold claw portions of the hook portion.

    摘要： There are provided a magnetic thin film utilizing a granular film and having excellent high frequency characteristics and a method of manufacturing the same, and a multilayered magnetic film and magnetic components and electronic equipment utilizing the same.A nonreactive sputtering is performed so that there is no oxidation of a magnetic metal, and a saturation magnetization is increased to increase a resonant frequency of permeability. Also, a multi-target simultaneous sputtering is combined with the nonreactive sputtering so that in a granular structure including magnetic grains and an insulating layer a size of the magnetic grains and a thickness of the insulating layer are optimized thereby ensuring a proper magnitude for a crystalline magnetic anisotropy within the grains and excellent soft magnetic properties. Further, the optimization of the thickness of the insulating layer has the effect of improving a resistivity, decreasing an eddy current and improving an exchange interaction between the magnetic grains.
