摘要： A power converter comprising a current-type inverter is disclosed, in which an output of a converter unit is applied as an input to the inverter unit through a DC reactor, and AC power is supplied to a load from the inverter unit. A ripple component of the DC input of the inverter unit is detected, and the switching elements of the inverter unit are controlled by modulation rate if they are to be subjected to PWM control, thus completing a sinusoidal waveform of the output of the inverter unit. Specifically, since the input to the inverter unit is allowed to contain a ripple, the DC reactor is reduced in size. The output of the inverter unit is a sinusoidal AC power containing no high harmonics and therefore the load is free of effects of high harmonics.

摘要： An image of an elevator hall or an inside of elevator car is acquired by photographing apparatus, and the number of waiting passenger is detected by comparing the above-mentioned image with a background image when no passenger is present at the elevator hall. Second image processing apparatus with high precision is prepared by the same image information as that of first image processing apparatus, teacher information derived therefrom is compared with an output from the first image processing apparatus. If the teacher information is not coincident with the output from the first image processing means, parameters required for performing the image process by the first image processing appartus, for instance, constants, threshold values and weight coefficients employed in an image processing algorithm are adjusted.

摘要： The present invention relates to a group control elevator system which has been adjusted to operate in response to a state of utilizing elevator cars. In a group control elevator system which carries out a control of allocating elevator cars to elevator car calls for serving many floors by using an evaluation function having a plurality of variable parameters, targets for elevator control performance are inputted, a traffic flow to which elevator car demand belongs is judged, variable parameters to be adjusted which have been set in advance for each combination of said targets and traffic flows are stored, stored variable parameters are adjusted, adjustment sequence of variable parameters to be adjusted is stored, and a plurality of variable parameters are sequentially adjusted according to the stored sequence. By the above arrangement, only desired parameters to be adjusted are selected and adjusted out of a plurality of variable parameters for desired targets and traffic flows. Accordingly, an increase in time required for adjustment can be restricted even if there has been an increase in the number of variable parameters to be adjusted.
