Abstract:
A sealing structure for sealing a valve body from a separating plate in a liquid-tight fashion. A first sealing layer is printed on the mating surface of the separate plate and a second sealing layer is printed along the first sealing layer with at least a part of the second sealing layer overlapping the first sealing layer and the printing height of the second sealing layer being made larger than that of the first sealing layer whereby the valve body and the separate plate are sealed liquid-tight from each other by a sealing portion comprising the first and second sealing layers. The sealing portion provided by the sealing structure of the present invention has the advantages that it hardly comes off, has an excellent sealing property and is capable of reducing the width thereof to meet a design change.
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.
