    摘要： In elevator equipment in which an elevator controller is connected by a common transmission line to an elevator cage and a plurality of apparatus installed at elevator stops on respective floors, signals are transmitted from the elevator controller to the elevator cage and the plurality of apparatus of elevator stops on respective floors. Information transmitted between the elevator controller and the cage as well as each apparatus at elevator stop on each floor is sorted into information which is different for each apparatus on each floor and the cage (unique information) and information which is the same for the plurality of apparatus at elevator stops on respective floors and the cage (common information), and the unique information is transmitted during a first period and the common information is transmitted during a second period, thereby reducing time required for transmission of information during one cycle.

    摘要： In a magnetic floating type of super high speed transportation system using a linear synchronous motor system as its drive system in which a field magnet is carried on a train and a series of armature coils are provided along a track, a speed of a train is regulated under control of a frequency converter of the variable frequency and voltage type for supplying power to the armature coils. For the speed regulation, a relative position of the field magnet to the armature coils is detected to form a train of position detecting pulses. A reference frequency pattern with a frequency corresponding to a speed command is formed. A phase difference between the reference frequency pattern and the position detecting pulse train is detected. A propulsion force command of a linear motor is obtained by setting different limit values in the positive and negative parts of the phase difference signal. A sinusoidal current waveform pattern is formed in synchronism with the position detecting pulse train. By multiplying the current waveform pattern by the propulsion force command, a sinusoidal armature current pattern is obtained of which the frequency and the crest value are fixed. The cycloconverter is controlled so as to provide an armature current following the armature current pattern, whereby the vehicle speed accurately follows the speed command.
