Inventor: SUGANO TADAAKI
IPC: G03G15/041
Filed: 1982-03-31
Abstract: PURPOSE:To obtain a large speed reduction ratio of a motor easily by interposing a feed screw between a mirror and a lens, and a motor. CONSTITUTION:To increase an image-forming magnification, a step motor 122 is operated to move a cam 110, a lens support, a lens 44 and a lever 113 to prescribed positions. Then, the 2nd scanner 10 moves slightly leftward while the movement thereof is regulated by a cam surface. If the 2nd device 10 is moved so as to scan from the start position, the magnified image of an original can be formed on a photosensitive drum 51. Thus, the image-forming magnification can be regulated indefinitely through the movement of the lens 44 and mirrors 30, 31 at desired positions. In the variable power operation that is accomplished in the above-mentioned way, the output of the motor 122 is decelerated by a feed screw 105; therefore, a large speed reduction ratio is obtained.

IPC: H04L27/22
Filed: 1988-03-09
Abstract: PURPOSE:To simply eliminate an ambiguity by bringing base band signal of two systems which have been reproduced to differential operation at every system and setting them to two kinds of ambiguities. CONSTITUTION:In a receiver 2, a synchronous detection circuit 7 establishes firmly a synchronization of a carrier wave and a bit discriminating clock from a four-phase PSK modulating signal which has been received, and reproduces base band signals I', Q' of two systems. Two differential operation circuits 8, 9 convert every system of the base band signals I', Q' to differential signals for obtaining an absolute value of a soft decided value difference. As a result, an ambiguity by a carrier wave reproducing phase of the differential signals of two systems can be limited to two kinds of I and Q of the same phase and Q and I of the opposite phase against convolution signals I, Q of two systems of a transmitter 1. A selecting circuit 10 selects by a selecting signal whether the differential signals of two systems inputted to an error correcting circuit 11 are set to the same phase or the opposite phase.
