Title: Multiplex transmission equipment
Inventor: KINOSHITA IKURO
Filed: 1985-04-12
Abstract: PURPOSE:To simplify the circuit by receiving with one terminal of primary station the start signal which is sent from the other terminal of the primary station to the plural number of secondary stations connected in loop to the primary station, adding the number to the counter at each cycle of reception, and detecting and processing the abnormality. CONSTITUTION:Plural number of secondary stations 2-5 are connected to a primary station 1 in loop by two-core transmission cable. A poling signal, start signal and data signal are sequentially sent out from an output terminal 1-0 of the primary station 1. Following the start signal, the data signal is inputted to an input terminal 1-i from one of the secondary stations. The secondary station takes in the poling signal, and if the signal is addressed to itself, it receives the data from the higher rank station and sends out its own data to the lower station. If not addressed to it, it simply transfer the signals sent from the higher station. The primary station 1 detects the abnormality when there is no start signal at its input terminal 1-i. Also it discriminates the abnormality of secondary station by counting the inputs of data signal. Thus, the multiplex transmission can be done by a simple circuit.

Filed: 1985-04-15
Abstract: PURPOSE:To obtain a proper developed image without reference to manufacture variance of a photosensitive body by controlling a developing bias by a potential measuring circuit corresponding to dark attenuation up to a development part which is detected before the start of copying operation. CONSTITUTION:Dark part potentials of potential sensors 11 and 12 provided before and behind the development part 4 are measured by potential measuring circuits 13 and 14 under the condition that the output of a primary electrostatic charger 2 before the start of copying operation is made constant. The mean value of their measured values is processed in a DC control circuit 15 as the dark part potential of the development part 4 to determine the developing bias which is suitable to the measured values. The determined developing bias is applied to a developing sleeve 10 by a high voltage transformer 16. Consequently, even when a photosensitive body 1 which has large dark attenuation is used, proper developed images has density above specific density are obtained without damaging a photosensitive body 1 owing to an increase in the quantity of primary charging.
