Title: Variable attenuating circuit
Inventor: SANO SHINYA
IPC: H03G3/02
Filed: 1982-06-01
Abstract: PURPOSE:To vary an attenuation variation curve from logarithmic linear characteristics by varying the attenuation step speed of a variable attenuator under digital control according to the position of an attenuation step. CONSTITUTION:Frequency division signals (a)-(e) are selected by a data selector 24 for output ranges A-E of an up/down counter 12 which supplies data on the attenuation step. Frequency division outputs of higher order than a frequency division output selected by the data selector 24 [e.g. (a) and (b) when (c) is selected] are regarded as one set to make the initial state of the frequency division output constant in case of transition of ranges. Thus, even when the variable attenuator under digital control performs attenuation at a specific ratio per step, its variation characteristics are expressed by a natural curve as well as a conventional variable resistor. Further, the frequency division outputs of higher order than the selected frequency division output are set or reset to exclude uncertainties of the variation characteristics.

Title: Cell transfer device
Inventor: KUSANO TOSHIHIKO
IPC: H04L12/28
Filed: 1996-04-17
Abstract: PROBLEM TO BE SOLVED: To provide a cell transfer device in which congestion is evaded while holding the transfer order of cells. SOLUTION: When the number of storing cells in an output buffer 21 exceeds a threshold level, a prescribed number of cells are transferred through a bypass line. A control cell indicating the number of bypass cells is inserted into the place of the missing bypass cells in a main line. The number of the bypass cells is recognized based on the control cell at a reception side. When the cells are stored in an input buffer 26, a null area for the portion of the bypass cells is provided after the storing area of the cell immediately before the control cell and the cell received from the main line, which is successively received after the control cell is stored in the area after the null area.
