  • Patent number: 5390765
    Abstract: In a program of running direction determination steps wherein the presence of a call signal, which is based on activation of floor call buttons provided in a cage of an elevator of hall buttons disposed at halls of respective floors, is repeatedly monitored so as to determine the running direction of the cage of the elevator. This program includes the cage running direction determination step of reversing the running direction of the cage with preference over any other call signal when a floor call in the rear of the cage has been registered anew while the cage is at rest at any of the halls.

  • Patent number: 5074385
    Abstract: A call registration apparatus for an elevator system includes a call registration lamp and a car call button disposed in an elevator car and connected by a common signal line to a CPU. When the call button is pressed a first time, the CPU registers a call and turns on the call registration lamp. When the elevator car reaches a floor, the CPU makes the call registration lamp flicker. If the call button is pressed while the lamp is flickering, the CPU performs a door opening or door closing operation.

  • Patent number: 4719993
    Abstract: In a case where peculiar control information which differs depending upon buildings is revised, a first memory for storing the revised information and a second memory for storing the original information before the revision are disposed, and addresses and contents are correspondingly stored in both the memories, whereupon the stored contents of both the memories are displayed on a display unit at the respectively corresponding addresses. Thus, the presence or absence of an alteration error in the case of the revision of the control information can be reliably checked.
