Title: Atm multiplexer
Inventor: KIN KEISHIYU
IPC: H04N21/2365
Filed: 1993-12-29
Abstract: PURPOSE: To prevent the deterioration of channel efficiency by storing an ATM cell input circuit in an input buffer by means of the signal that notifies the beginning of a cell. CONSTITUTION: An ATM cell input circuit is constructed so as to be stored in an input buffer by the signal that detects the cell synchronization with an input signal and notifies the beginning of a cell. An ATM cell input circuit part includes a header buffer and a payload buffer which store the headers and payloads separated and extracted from the cells supplied to each input, and the separated headers are analyzed for decision of the cell transmission sequence. The buffer overflow conditions are decreased by a priority encoder which processes with preference the input terminal where many cells are stored in the buffer and reduces the load of the input terminal having heavy traffic load.  The header value is changed based on the decision sequence of the FIFO storage level information on every input terminal, and the cell transmission sequence is decided based on the service priority. Thus, the deterioration of channel efficiency is prevented.

Title: Toner supply device
Inventor: ITO AKIHIDE
IPC: G03G15/08
Filed: 1998-12-16
Abstract: PROBLEM TO BE SOLVED: To surely supply toner to a developing part even when the toner is nearly used up. SOLUTION: The inclination of the supporting member 5 of a toner container 4 is changed according to the residual quantity of toner in the container 4. At an initial time that the container 4 is filled with the toner, the toner is supplied to the developing part 2 by inclining the container 4 by a fixed angle by making a toner supply port 7 face upward so that the toner in the container 4 is prevented from being concentrated and condensed at the port 7 or near it. When the toner is nearly used up, the container 4 is inclined so that the port 7 is set more downward than the bottom part of the container 4. Thus, the toner is stably supplied to the developing part 2 from the port 7 of the container 4 even when the toner is nearly used up.
