    摘要: In an intake valve phase control after an engine stop command is issued, a stop-time phase is used as a target value. In the intake valve phase control, when the mode changeover condition is not satisfied, and an electric motor that serves as an actuator is not in a locked-state, the highest-speed mode, in which the amount of electric power supplied to the electric motor is fixed to the maximum value, is selected to reliably change the intake valve phase by a required amount. Then, the intake valve phase comes close to the stop-time phase and the mode changeover condition is satisfied, the control mode is changed from the highest-speed mode to the normal mode to set the control phase to the stop-time phase with higher accuracy, and the feedback control over the intake valve phase is executed.

    摘要: An actuator operation amount setting unit prepares the rotational speed command value for an electric motor such that the phase of an intake valve changes in accordance with the target phase. An electric-motor EDU controls the motor supply electric power such that the electric motor operates in accordance with the rotational speed command value. An overheating determination unit determines whether at least one of the electric motor and the electric-motor EDU needs to be restricted from heating up based on a result of comparison between the information indicating the motor supply electric power and the reference value. A rotational speed command value restriction unit restricts the rotational speed command value provided to the electric-motor EDU to a value within a predetermined range, when it is determined that the at least one of the electric motor and the electric-motor EDU needs to be restricted from heating up. A reference value setting unit variably sets the reference value based on the rotational speed of the electric motor.

    摘要: A cyclic sewing machine includes a cam disc provided at opposite surfaces thereof with a first cam groove and a second cam groove, respectively. A first transmitting member has movement derived from the first cam groove operatively selectively imparted thereto and a second transmitting member has movement derived from the second cam groove selectively imparted thereto. First and second link mechanisms are connected to the first and second transmitting members, respectively. The cyclic sewing machine also includes a switching mechanism for selectively operatively connecting the first cam groove to the second link mechanism and the second cam groove to the first link mechanism, respectively. Thus, in the cyclic sewing machine, bar tacks may be rotated 90 degrees by manipulating the switching mechanism.

The heater is a heating element that is opposed to the flat surface of the battery. A shielding plate is arranged between the heating element and the flat surface of the battery. The heat dissipating plate that is thermally coupled to the heating element is secured to the case on the surface side of the case. In the hand warmer, the flat surface of the box-shaped rechargeable battery, the shielding plate and the heat dissipating plate are arranged in a stack structure. The heat dissipating plate is heated by the heating element.
