Abstract:
A combined semiconductor device composed of a plurality of semiconductor elements each molded with an insulating material such that the semiconductor element with lead wires is coated with the insulating material down to an appropriate position of each lead wire so that the remaining part of each lead wire is exposed for connection with other circuit elements, the molded semiconductor elements being connected with each other in a bridged manner with interspaces therebetween by means of an insulating material the same as or similar to the molding material.
Abstract:
In an elevator system comprising a plurality of elevator cars each serving a plurality of floors, an elevator control device is provided in which each car has a service zone, hall calls within which the particular car is capable of answering, which service zone is changeable at any moment according to the changing traffic situation, any hall call generated from a floor being transmitted only to that car the service zone of which includes such a floor. Lest the service zone of a car includes so many floors that it is not certain whether or not the particular car is able to serve the farthest floor included in its service zone in a reasonable time, a maximum length or size of the service zone is predetermined thereby to prevent the car from answering a hall call from an extremely far floor.
