The locking mechanism is adapted to a door system having a door unit slidably mounted to a door frame to open and close by sliding longitudinally along the door frame. The locking mechanism includes: a pivoting member pivotally mounted to one of the door frame and the door unit for pivoting about a pivot axis, and a hook member spaced apart from the pivot axis such that the hook member can pivot about the pivot axis via the pivoting member; and a guide member secured to the other one of the door frame and the door unit, the guide member having a channel formed therein to receive the hook member when the pivoting member is moved toward the guide by said sliding of the door, and subsequently maintain engagement with the hook member.

The present invention relates to an alternating current electrical motor having a first element with magnets of alternating polarities, and a second element with electrical conductor coils, the first and the second elements being mounted for relative motion to one another. A controller for the electrical motor comprising: a current source for energizing the coils with an alternating current to produce a movement of the first and the second elements relative to one another; a sensor for sensing a phase shift between the magnets and the current in the coils; and a current source controller for varying an amplitude of the current to substantially regulate the phase shift to an optimum phase shift value, thereby providing a minimum power consumption for proper operation of the electrical motor.
