Abstract: According to a method for controlling an automatic door of the present invention, even when an accidental condition occurs due to some obstacle clogging a traveling lane of the door, the door can move at a high speed to its deceleration point so as to immediately enable a man to go through the door opening, while the door is prevented from colliding at a high speed against the obstacle repeatedly to make it possible to increase both the durability and safety of the door.

Abstract: In a method for controlling an automatic door system, after a power-supply switch of the system is turned on, a door of the system initially conducts its low-speed opening/closing operation when a first human-body detection signal is inputted to the system; and then, when the door travels a distance more than a predetermined minimum door stroke, the door conducts its normal-speed opening/closing operation after completion of its traveling the predetermined minimum door stroke to enable the door to conduct its normal-speed operation within a short time after the power-supply switch is turned on.

Abstract: A pull tab connector for slide fastener sliders comprises a closed loop formed of a piece of resilient wire and having a pair of stems projecting from the loop, the stems being juxtaposed and overlying each other. The stems are aligned with each other in a plane perpendicular to the general plane of the loop. In use, the stems of the loop are angularly moved about one another until they are aligned with each other in the general plane of the loop. Then the stems are inserted in an axial hole in a pull tab, while a pair of bottom portions of the loop are received in a transverse recess in the pull tab which recess communicates with the axial hole.
