Abstract: A semiconductor substrate has on its surface an impurity, well of different conductivity. The impurity well has a second impurity well of the same conductivity as that of the first one therein. The second impurity well has a higher impurity density and a lower depth than the first one. The second impurity well has a third well of the same conductivity as that of the substrate therein. The memory cell array, consisting of field effect transistors, has its source and drain at the impurity wells.

Abstract: 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.

Abstract: An elevator control system for controlling movement of cages up and down in accordance with the situation of waiting persons in landing places or passengers in the cages detected by image pickup devices and other detecting devices includes first and second image processors, the image processing level of the second image processor being not lower than that of the first image processor. The system further includes an elevator controller for controlling movement of the cages up and down, the elevator controller including a device for applying the result of image processing performed by the first image processor to the control of the cages, and a device for applying the result of image processing performed by the second image processor to the control of the cages when the image processing is carried out based on the result of image processing performed by the first image processor and other information pertaining to passengers and waiting persons detected by the other detecting devices.

Abstract: Elevator group supervisory control method and system for group supervisory control of a plurality of elevators serving a plurality of floors. The method and apparatus of the invention permits the inputting of qualitative requests (guidance), from the user, concerning elevator operation into the group supervisory control system. Qualitative requests concerning elevator operation are set in the form of guidance (or request) targets. The thus set request targets are converted into control targets for the elevators. Actual group supervisory control is executed using the control targets.
