    Abstract: A switching power source having a digital control system is provided. The switching power source includes a switching circuit 40 for switching an input power, an output circuit 50 for converting the switching output into a DC output, and a digital control 70. The digital control 70 is adapted to receive an output voltage analog signal AS1 and an output current analog signal AS2, and to convert the signals AS1 and AS2 into digital signals. It further functions to calculate, based on the digital signals, a command value for determining at least one of the switching frequency and the on or off time of the main switch 42. The operation of the main switch 42 is controlled in accordance with the command value. Information on power source input voltage or load terminal voltage is obtained through an assumption based on the signals AS1 and AS2.

    Abstract: A linear motor driven elevator including in an elevator shaft, a fixed portion, an upper turning portion, and a lower turning portion. An ascending passage and a descending passage are sectionally formed between both turning portions in the fixed portion in a manner that the passages are positioned oppositely. A plurality of cages are accommodated in the passages, the cages being provided with permanent magnets which oppose the linear motor primary coils. Locking mechanisms for selectively locking the cages in position are provided. The turning portions each include a motor driven turn table which rotates the cage about the center axis of the elevator shaft to switch from the ascending to the descending passages and vice versa.
