Abstract: An elevator target floor registration unit, which displays an estimated amount of time until an assigned elevator car arrives, reduces feelings of uneasiness. Various target floor registration units by which a user may register a target floor are installed on respective floors of a building. The target floor registration units are connected to an elevator controller via an interface. The elevator controller: (a) assigns a most suitable elevator car corresponding to a user's target floor registered using the target floor registration unit; (b) computes an expected waiting time for the elevator assigned to arrive at the floor of the aforementioned registration; and (c) sends said pieces of information on the elevator assignment and the expected waiting time to aforementioned target floor registration unit in order to display them.

Abstract: Destination calls entered by means of buttons (21-29) are each given a designation unique to the car and pick-up floor for that call and other calls to be serviced therewith, such as a letter (A-E), which is different from any other outstanding calls. Calls can be reassigned among elevators (UL, LL, UR, LR) whether they are in the same or different hoistways (LF, RT). Signs (31-39, 41-49) adjacent each hoistway are illuminated to display the designation of any call which is being answered by an elevator car approaching the floor. Thus, passengers are informed when their call is being answered by the signs identifying the call, rather than identifying any particular car. Another embodiment identifies (60, 31a, 41a) the hoistway landing doorway (1, 2) as well as a letter to allow passengers to wait adjacent to the hoistway landing doorway of the car which will serve them.

Abstract: An elevator traffic control technique includes destination grouping that is selectively implemented during selected traffic condition. One example includes determining when up peak traffic conditions exist. If so, the passenger-to-car assignments are grouped based upon the passengers' desired destinations, which are determined before the passengers enter elevator cars, Arranging sectors responsive to current traffic conditions in one example is based upon elevator passenger traffic patterns over the most recent five minutes.

Abstract: An elevator system includes a controller that uses one of a plurality of fuzzy logic algorithms for assigning an elevator car to service a passenger request. One example uses a passenger's desired destination as indicated by the passenger service request prior to the passenger entering an elevator car. One example includes multiple fuzzy logic algorithms, each corresponding to a particular relationship between an elevator car's current assignments, a passenger's desired destination, a source landing of the passenger's request, or a combination of them.

Abstract: A elevator traffic control technique includes destination grouping that is selectively implemented during selective traffic conditions by a system controller (36). If, for example, an up-peak traffic condition exists, passenger-to-car (30,20) assignments are grouped bused on passengers' desired destinations.

Abstract: An upper plate is arranged on the top surface of a lower vertical plate to form a T-type joint, and a penetration promoter is applied on the surface of the upper plate of the T-type joint. Subsequently, when performing non-consumable electrode arc welding, a penetration width w of a molten pool on the side of the vertical plate after penetrating through the back side of the vertical plate is formed equal to or greater than the vertical plate thickness if a lower vertical plate thickness is the same thickness as an upper plate thickness or thinner than the upper plate thickness, and the penetration width of the molten pool is formed equal to or greater than the upper plate thickness if the lower vertical plate thickness is thicker than the upper plate thickness, thereby forming a penetration shape having a desired welding metal part.

Abstract: A flame retardant union fabric obtained by combining (A) 30 to 70% by weight of a fiber comprising as a main component a flame retardant halogen-containing fiber made of a composition comprising 100 parts by weight of an acrylic copolymer of 30 to 70% by weight of acrylonitrile, 30 to 70% by weight of a halogen-containing vinyl monomer and 0 to 10% by weight of a vinyl monomer copolymerizable with them, 10 to 30 parts by weight of an antimony compound and 8 to 30 parts by weight of a zinc stannate compound, with (B) 70 to 30% by weight of a cellulosic fiber. The flame retardant union fabric shows a high flame resistance which passes the M1 class of NF P 92-503 burning test in France even after the post-treatment.

Abstract: An elevator system (20) includes a controller (36) that uses one of a plurality of fuzzy logic algorithms for assigning an elevator car (22-28) to service a passenger request. A disclosed example uses a passenger's desired destination as indicated by the passenger service request prior to the passenger entering an elevator car. A disclosed example includes multiple fuzzy logic algorithms, each corresponding to a particular relationship between an elevator car's current assignments, a passenger's desired destination, a source landing of the passenger's request, or a combination of them.

Abstract: A control device for a double-deck elevator system having an upper deck and a lower deck, includes a group control device for assigning the upper and lower decks to respond to car calls from the upper and lower decks and boarding hall calls from a plurality of floors. The control device further includes an assignment control device for determining whether a plurality of the car calls and boarding hall calls can be responded to simultaneously and for directing said group control device to reassign the upper and lower decks to respond to the plurality of car calls and boarding hall calls simultaneously.

Abstract: In a control device for double-deck elevator systems equipped with a plurality of elevators that have an upper deck and a lower deck that are conveyed simultaneously to two adjacent floors and that assign elevator decks to respond to boarding hall calls from each floor, to select the optimal deck for responding to boarding hall calls is selected from among all of the aforementioned decks to make elevator travel and passenger transport more efficient.

Abstract: An elevator system (10) includes an elevator car (18) supported for vertical movement on a belt (16) having an end fixed to the hoistway (26) and the other end wound about a drum (32) of a drum drive (12). When the belt (16) is wound or unwound about the drum (32), the elevator car (18) is raised or lowered, respectively.
