    摘要: A diffuser apparatus includes a diffuser communicating radially outwardly with an exit of an impellor. The apparatus includes a housing with a plate that is rotatable about a rotational axis and forms a hub side wall. A side surface of the plate has a vane having one circumferential end fixed to the plate; the other end is movable in the direction of the axis. The housing includes an inclination path with one end opened to the hub side wall to bendably guide the vane so that the other end of the vane moves in the circumferential direction upon rotation of the plate and moves in the direction of the axis to a projected position to project into the diffuser. An actuator rotates the plate to drive the vane between the projected position and a retracted position where the other end is retracted into the hub side wall.

    摘要: A control apparatus for an internal combustion engine includes a turbocharger; an exhaust gas purifying catalyst which is arranged at a section downstream of a turbine in the exhaust passage; and a low pressure EGR passage which connects a section downstream of the exhaust gas purifying device in the exhaust passage and a section upstream of a compressor in the intake passage. The compressor is provided with a movable vane mechanism capable of varying throttled quantity of a flow passage of intake gas by moving diffuser vanes. The movable vane mechanism is controlled so that the throttled quantity of the flow passage is decreased when the exhaust gas is led to the compressor via the low pressure EGR passage as compared with a case when the exhaust gas is not led to the compressor.

    摘要: An air flow amount passing through a centrifugal compressor is acquired on the basis of outputs of an air flow meter. A surge limit compressor rotation speed is acquired on the basis of the obtained air flow amount passing through the compressor. A current compressor rotation speed (turbo rotation speed) is acquired by a turbo rotation speed sensor. A rotation speed of the compressor is controlled on the basis of the surge limit compressor rotation speed and the current compressor rotation speed. More specifically, while being limited so as to be equal or less than the surge limit compressor rotation speed, a target compressor rotation speed is controlled so as to be a value according to the operating conditions, such as accelerator opening and engine speed, of an internal combustion engine. In addition, the surge of the compressor is judged on the basis of the surge limit compressor rotation speed and the current compressor rotation speed.

    摘要: End-mill machining control method and apparatus in which cutting forces tangential and normal to tool motion are detected and machining is controlled based on the detected cutting force values. A primary component Ft and motion axis components Fx, Fy of a cutting force are determined from current values of a spindle motor and motion axis motors for tool feed. A cutting-engaged angle αen is determined from a radius R of a tool and a depth of cut I into a workpiece. A motion direction angle β is determined from distribution motion amounts ΔX, ΔY to the axes. The cutting forces Fm, Fs tangential and normal to tool motion are determined from the primary component Ft and a motion axis component Fx or Fy whichever is the largest, the cutting-engaged angle αen, the motion direction angle β. The accuracy of the determined cutting forces Fm, Fs is high since they are determined from the primary component Ft less affected by disturbance and the largest axis component of the cutting force. By controlling the cutting forces Fm, Fs tangential and normal to the tool motion, machining accuracy can be improved and tool life can be extended.
