An electrode roll drying device includes a drying oven housing an electrode roll, an outer-side heater configured to heat the electrode roll, an axial-side heater configured to heat the electrode roll, a pressure reducer configured to reduce internal pressure of the drying oven, a sensor configured to detect a temperature of an outermost portion of the electrode roll, and a control unit configured to control operation of the outer-side heater, the axial-side heater, and the pressure reducer. The control unit is configured to operate the outer-side heater and the axial-side heater to heat the electrode roll from the outer-side and winding core side, and, when the temperature of an outermost portion reaches a target temperature, stop operation of the outer-side heater, operate the pressure reducer to reduce the pressure within the drying oven, and carry out the heating by the axial-side heater and the pressure reduction by the pressure reducer.

In an electromagnetically operable engine valve assembly including a controller for an internal combustion engine, a stable initialization is achieved which suppresses a collision of a movable element against an electromagnet to cope with a viscosity of a lubricating oil during an engine start under an engine low temperature. A supplied current value is feedback controlled in accordance with a position of movable element when an initialization control such that a current is continuously supplied to one of electromagnets is executed. At this time, the feedback control gain G is, first, set to a relatively small value and is, thereafter, switched to a relatively large value at a gradual pace for each execution of the initialization control until the initialization control has succeeded in moving the movable element to an initial position.
