摘要： A stepping drive unit for cameras which is capable of stepwise driving a photographic optical system by operating a member which is placed into a reciprocating motion by means of an electromagnetic force on a plane substantially parallel with the photographic optical axis and not through a cam, whereby the transmission efficiency of a drive cam is increased. The drive is also capable of eliminating the need to employ a stepping drive in returning the photographic optical system to an initial position whereby the number of steps taken by the stepping drive is reduced, and of conducting its functions without applying any excessive impulsive force by stepwise increasing the amount of electricity charged to the electromagnetic drive member as the number of steps taken by the stepping drive increases, whereby the level of mechanical driving sounds is greatly reduced.

摘要： A radio communication system for mobile communications, or more specifically, a radio receiver for a base station which receives signals transmitted from a plurality of mobile stations is provided wherein the propagation characteristics of channels with respect to a frequency domain can be instanteously measured at all times even while the channels are in use. A frequency converter collectively receives signals transmitted from the mobile stations and converts the signals to IF-band signals, respectively. The IF-band signals output from the frequency converter are set apart from one another by corresponding ones of frequency differences of the signals transmitted from the mobile stations. Complex Fourier transform deriving means collectively derives the complex Fourier transforms of these IF-band signals, and outputs the resulting frequency spectra to analyzing means. The analyzing means simultaneously analyzes the propagation characteristics of the individual received waves, based on the frequency spectra supplied thereto. In accordance with the results of the analysis, a wave having excellent propagation characteristics is received.
