Abstract: PROBLEM TO BE SOLVED: To prevent a write address and a read address from being run over at reset in a buffer for a Audio Engineering Society(AES)/European Broadcasting Union(EBU) audio signal re-configuration and to reduce the scale of the hardware by employing a required minimum memory capacity for the buffer. SOLUTION: A serial digital video signal where an AES/EBU audio signal being data is multiplexed on an auxiliary signal area is converted into a parallel digital video signal by an S/P converter 1, a demultiplexer 2 demultiplexes audio data of the auxiliary signal area from the parallel digital video signal, the audio data are stored in a buffer 3, in which the data are re-configured and outputted sequentially. The output audio data of the buffer 3 are converted into the original AES/EBU audio signal by a format converter 4. In this case, a buffer size per channel of the audio signal in the buffer 3 is selected to be a divisor of a sample number of the AES/EBU audio signal with a reference sampling frequency with respect to a video signal frame period specified in advance.

Abstract: PURPOSE: To enable high speed charging by connecting a first and second output units, comprising a transformer and a rectifying unit, respectively, in parallel, setting the no-load voltage of the first output unit to a value higher than that of the second output unit, setting the output current of the first output unit to a value lower than that of the second output unit, and using both of the first and second output units in the early stage of charging. CONSTITUTION: Output units A and B are designated as first and second output units, respectively, and are connected with each other in parallel. The no-load voltage of the output unit A is set to a value higher than that of the output unit B, and the output current IX of the output unit A is set to a value lower than that IY of the output unit B. The output unit A includes a transformer TR1 and a rectifying unit S1, and the output unit B contains a transformer TR2 and a rectifying unit S2. Diodes D1, D2 are connected to equate the polarity of the rectifying units S1, S2 on the output side. This enables the charging of accumulators, wherein a passive-state film is formed and thus higher voltage is required, and high speed charging, wherein higher current is required, with a simple apparatus.

Filed: 1986-11-29
Abstract: PURPOSE:To securely prevent a photosensitive body from damaging when an image is formed by using some breadthwise part of the photosensitive body by operating and controlling a preliminary electrostatic discharging means so that toner sticks slightly to the substantially overall width of a no-image area on the photosensitive body where no toner image is formed in correspondence to the no-image area. CONSTITUTION:A control means 58 turns on the lamps 54 and 56 of the preliminary electrostatic discharging means 7 with DELTAt time delay as compared with the formation of images in a center area 58 and both side areas 60, and then turn off only the lamp 54 a time (t1+t2+t3) after a corona discharger 6 for charging is excited. Charges, therefore, remain on the surface of the photosensitive body 3 to the substantially overall width and the part where the charges remain on the photosensitive body 3 passes through a development area to stick toner. The toner is not transferred to transfer paper, but conveyed to a cleaning area and removed from the surface of the photosensitive body 3 with an elastic blade. Consequently, the photosensitive body 3 is prevented from damaging.
