摘要： A valve timing control apparatus includes a housing that is rotatable with a crankshaft; a vane rotor that is rotatable with a camshaft; and a phase controller to compulsorily change a rotation phase of the vane rotor alternately between an advance side and a retard side with respect to the housing if an engine shifts to a high rotation state after the engine continuously has a low rotation state for a predetermined period or more. The engine in the low rotation state has a rotation speed lower than a predetermined rotation speed. The engine in the high rotation state has a rotation speed equal to or higher than the predetermined rotation speed.

摘要： A fluid brake device has a brake shaft which penetrates a case. The case provides a fluid chamber for a magneto-rheological fluid. A magnetic seal has a magnetic seal sleeve which holds a small amount of the magneto-rheological fluid by magnetic flux. In addition to the magnetic seal, an axially pumping element is provided on an axial outside of the magnetic seal. The axially pumping element is provided by a shaft helical groove formed on an opposing wall of the brake shaft and/or a case helical groove formed on a surrounding wall. As the brake shaft rotates, the helical groove pushes the magneto-rheological fluid back to the magnetic seal. A combination of the magnetic seal and the axially pumping element may reduce leakage of the magneto-rheological fluid.

摘要： A fluid brake device has a case defining a fluid chamber. Magneto-rheological fluid is contained in the fluid chamber. A brake member is rotatably supported on the case and receives a braking torque according to the viscosity of the magneto-rheological fluid. The device has a movable member driven by a thermo-sensitive wax so that a volume of the fluid chamber is increased as the temperature in the fluid chamber is increased. The movable member is driven to maintain a pressure in the fluid chamber within an allowable range when the temperature in the fluid chamber is changed.

摘要： A device and associated method for controlling ignition timing of an internal combustion engine are provided. By comparing a determination value and knock magnitude, determination of knocking is made, and ignition timing is advanced or retarded. The device includes an operation unit that sets a correction amount of the determination value to a value corresponding to a degree of change of the determination value over time. The operation unit calculates, at a first timing, a first value related to an average value of the determination values; and calculates, at a second timing later than the first timing, a second value related to the average value of the determination values. The degree of change of the determination value is calculated as a difference between the first value and the second value.
