摘要:
A paper retainer assembly for attachment to a feed-in mechanism at a paper inlet or a feed-out mechanism at a paper outlet, includes a flexible, linear paper retainer, such as a metal or plastic wire. The paper retainer is operable to be extended to an extended position for use and retracted to a retracted position when not in use. The assembly also includes a locking mechanism operable to maintain the paper retainer in the extended position.

In a radio tele-communication system of this invention, at least one radio frequency is shared by a plurality of base stations and a plurality of mobile stations, a signal transmitted at the radio frequency has a time frame constituted by a plurality of time-divisionally multiplexed time slots, and time intervals for detecting timing shifts are set between the plurality of time slots. In at least either the base stations or mobile stations, a communication timing shift in a time slot currently used for communication is detected from a reception state in one of the time intervals for detecting timing shifts, and the communication timing of the corresponding time slot is corrected in cooperation with a station, with which communication is performed, on the basis of the communication timing shift detection result.

A control device for an ultrasonic motor for controlling to drive the ultrasonic motor according to a logical AND operation between a control pulse having a duty ratio changing from 100% to 0% according to a moving position of the ultrasonic motor and a driving signal having a resonance frequency of the ultrasonic motor. Accordingly, after starting the ultrasonic motor at a maximum speed, a moving speed of the ultrasonic motor can be gradually reduced until it reaches a target position, and when reaching the target position, the ultrasonic motor can be stopped precisely at the target position.

A digital signal multiplexing apparatus has n (n is an arbitrary integer) multiplexing circuits (11-1n) for converting input signals from a plurality of lines into m (m is an arbitrary integer) parallel signals which are added with added bits and have a first transmission speed. A parallel-serial conversion circuit (40) converts the m parallel signals from the n multiplexing circuits into a serial multiplexed signal by a parallel-serial conversion. A bus (30) connects the n multiplexing circuits and the parallel-serial conversion circuit. The n multiplexing circuits respectively have a circuit for successively transmitting the m parallel signals to the bus using a pluse signal having a second transmission speed which is n times the first transmission speed. A digital signal demultiplexing circuit has a serial-parallel conversion circuit (75) for converting a serial input signal into m (m is an arbitrary integer) parallel signals having a predetermined transmission speed. N (n is an arbitrary integer) demultiplexing circuits (51-5n) demultiplexes added bits from the m parallel signals from the serial-parallel conversion circuit (75) and outputs the added bits on a plurality of lines with the predetermined transmission speed. A bus connects the serial-parallel conversion circuit and the n demultiplexing circuit (75). The n demultiplexing circuits respectively have a circuit for receiving the m parallel signals output on the bus from the serial-parallel conversion circuit with a clock timing of a speed identical to the predetermined transmission speed.
