Abstract: PROBLEM TO BE SOLVED: To continue synchronous communication in a synchronous network system on deterioration in quality of a clock signal by automatically selecting another clock signal with respect to the clock management method in a synchronous network system and transmitter. SOLUTION: A clock changeover section 5 selects a clock signal among a plurality of clock signals including a clock signal received and extracted by transmission/reception sections 1, 2 of the transmitter of a synchronous network system and a clock signal from an external clock source 3 based on quality information transferred with each clock signal and inputs the selected clock signal as a master clock signal to a clock generating section 4. The clock generating section 4 generates a clock signal and gives it to the transmission/reception sections 1, 2.  A quality discrimination processing section 6 refers a synchronization management table 7 where a threshold of the quality level of the clock signal is set and a quality control table 8 which converts quality information into a quality level to send warning when the quality level of the quality information of the master clock signal is deteriorated more than the threshold.

Filed: 1994-10-05
Abstract: PURPOSE: To substantially enhance the resolving power by a relatively simple method by providing a changeover switch between the common electric wiring of a first LED array and that of a second LED array. CONSTITUTION: When the LEDs of a first LED array 2 are selectively brought to a continuity state in such a state that a second LED array 3 is set to a non-continuity state, signal light is condensed on the photosensitive surface of a photosensitive drum 8 through a lens array 9 to form latent images. Next, when a changeover switch is changed over to the second LED array 3 to set the LEDs of the first LED array to a non-continuity state and the LEDs of the second LED array 3 are selectively brought to a continuity state, latent images of a constant pitch are formed between the above mentioned latent images. In this case, latent images are synthetically formed on the first and second LED arrays 2, 3 to form a latent image of high resolving power. Therefore, resolving power can be enhanced without altering the LED forming density of the LED arrays 2, 3.

Abstract: PURPOSE:To obtain a ghost eliminating device where the circuit scale of a transversal filter is decreased remarkably by providing an input amplifier and inputting two output signals to each gain control circuit via a switch circuit. CONSTITUTION:Since an in-phase and an opposite-phase signal to an input signal are obtained at an output of the input amplifier 300, a non-inverting signal is fed to the position (a) of a switch circuit 320 and an inverting signal is fed to the position (b). In order to obtain an in-phase ghost compensation signal having a delay time 2 and an amplitude of -6dB, the circuit 320 connected to a gain control circuit 310 shown in C2 is closed to the position (a) by a control circuit 140 and a signal in phase to the input signal is inputted to the circuit 310, then the circuit 140 sets that the amplitude of the output signal of the circuit 310 is -6dB. In closing the circuit 320 to the position (b), the similar opposite phase ghost compensation signal is obtained. In the transversal filter 110 above, since only one circuit 310 is required to each delay element 200, the circuit scale is saved remarkably.
