Abstract: In an operating system for an elevator wherein operation means are disposed in a plurality of cages, cipher code memory means for storing predetermined operating sequences of the operation means are disposed for the respective cages, and switching means are disposed for comparing operating sequences of the corresponding operation means with the stored predetermined sequences when the operation means are operated and to switch the corresponding cages to predetermined runs when the operating sequences agree; an common cipher code alteration means is provided for altering the stored predetermined operating sequences to different operating sequences for all the cages.When the cipher code alteration means is manipulated, all the cipher code memory means are commanded to alter their cipher code contents at once, whereby the single altering manipulation suffices to complete the cipher code alterations for all the cages.

Abstract: When a plurality of preset buttons among a plurality of buttons provided on a destination call registration panel have been successively depressed in a predetermined sequence and within predetermined time intervals, the presence of a request for a special operation is determined so as to register a call to a specified floor not indicated on the panel. When the request for special operation is not determined, a call to a floor corresponding to a depressed button is registeed as usual. In this manner, the destination floor call registration panel can be used for registering cage calls under normal operation and for instructing special operation without any change.

Abstract: In an elevator having destination buttons provided on halls of a plurality of floors for appointing destination floors requested by waiting passengers, an operating apparatus for controlling operations of the elevator which is capable of tracking movement of waiting passengers that have depressed the destination buttons. Upon detecting that a passenger has gotten into the cage, only the destination call requested by this passenger is automatically registered as a cage call, whereas the destination call of a passenger not having gotten into the cage is cancelled. A destination call requested by a passenger is also cancelled under the condition that this passenger has egressed from the elevator hall.

Abstract: A demand estimation apparatus wherein one cycle of a demand fluctuating substantially cyclically is divided into a plurality of sections having predetermined time widths, the demand is measured by cumulating demand measurements taken a varying number of times for each section and assigning an increasing weighting parameter for successively newer measured values, an estimated demand for each section is calculated based on the measured values for the section and a weight coefficient, and the weight coefficient is changed in accordance with the number of times of cumulation of demand measurements.

Abstract: A group-controlled elevator in which each hall is provided with destination buttons that will be manipulated by passengers and that produce signals corresponding to destination floors desired by the passengers, and in which destination calls produced by the manipulated destination buttons are automatically registered for predetermined cages. When a cage other than the cage for which the destination call is automatically registered, has arrived at the floor where said destination buttons are manipulated, the destination call is also registered even for this non-allotted cage. Therefore, whichever cage the passengers are on board, they are brought to their desired floors without the need of registering again the calls in the cage.

Abstract: An apparatus for estimating the traffic demand value of elevators wherein the period of time of elevator operation is divided into a plurality of sections, the traffic demand value for each section is measured, and an estimated traffic demand value of a corresponding section is estimated on the basis of the measured value. A weight coefficient is provided in accordance with a result of the comparison between the estimated and measured demand values to prevent the estimated value from greatly differing from the actual traffic demand whereby the elevators can be accurately group-supervised as intended.

Abstract: This spool for ribbons, tapes, string, and the like comprises a plastic first cylinder, which ribbons or tapes are coiled around. A projecting flange along one edge of the cylinder helps to hold the ribbons or tapes coiled around it. Fitted inside the first cylinder is an adjustable second cylinder made of the same material. This adjustable second cylinder provides a second flange and includes a series of openings, each having a series of steps, any one of which can engage a projection rib on the inner surface of the first cylinder. The width between the two flanges is thereby determined, and the two cylinders may then be secured in the selected position.

Abstract: An apparatus wherein a demand fluctuating substantially cyclically is divided into a plurality of sections having predetermined time intervals and wherein the demand is estimated for each section on the basis of the measured result of the demand in the section, characterized in that an adjusting section is set in the vicinity of the boundary between two sections adjoining each other, and that the estimation value of the demand in the adjusting section is compared with the respective estimation values of the two sections, so as to shift the boundary in the direction of widening the section which has the estimation value closer to the estimation value of the adjusting section. Thus, the demand in the vicinity of the boundary is estimated with the estimation value of the widened section, and it can be estimated at high precision.

Abstract: A control apparatus for elevators in which one cycle of a fluctuating demand is divided into a plurality of sections, the demand in each section or a service condition value of the elevators for the demand is measured, the demand or the service condition value of the corresponding section is estimated from the measured value, and decision means is comprised to compare the estimated value and the measured value obtained anew and to decide the compared result, so that when the compared result has been decided to fail in satisfying a reference condition, cages are controlled with a value set separately from the estimated value or a value separately calculated for estimation. This brings forth the effect that, even when the measured value has become different from an ordinary value due to the occurrence of a special traffic condition, it is not used for the calculation of the estimative value, so as to permit an accurate estimation when an ordinary traffic condition has been thereafter restored.
