Title: Input signal buffer circuit
Inventor: HIRANO HIROSHIGE
IPC: H03K17/04
Filed: 1990-11-14
Abstract: PURPOSE:To prevent malfunction by connecting a second complementary MOS transistor(TR) to input a signal which is of the same phase as an input signal and a third complementary MOS TR to input the signal which is of a phase opposite to the input signal and in addition, is delayed in parallel to a first complementary MOS TR group to which the input signal is inputted. CONSTITUTION:When delay time caused in NOT circuits INV2 to INV6 elapses after the input signal I is transferred from logical voltage 'L' to logical voltage 'H', a node N12 turns to logical voltage 'L', and the TRs Qp14, Qp15 are turned ON, and the TRs Qn14, Qn15 are turned OFF, and since an input switching level is shifted to a High side, the input signal I becomes easy to transit to logical voltage 'L'. Namely, the blind sector of the input switching level after the lapse of definite time from the transition of the input signal I becomes small. Thus, an input signal buffer circuit causes a few malfunctions due to reflection, etc., until some period of time elapses after the transition of the input signal I, and it responses to the transition of the input signal at high speed.

IPC: H04L12/40
Filed: 1991-11-26
Abstract: PURPOSE:To avoid the deterioration of the response of a system and the dead lock of the system by appropriately setting the maximum packet length, in the LAN of a CSMA/CD system. CONSTITUTION:This system is equipped with an arithmetic means (#3) which calculates a through-put S based on each information of a packet length Lp, number of packet Np, transmitting speed R, and activating time T, a first table (#4) which searches an average packet generating interval K based on the calculated through-put S and the maximum packet length Lm. And also, the system is equipped with a second table (#5) which searches the maximum packet length L for escaping the deterioration of the response of the system and the dead lock of the system based on the average packet generating interval K and the present maximum packet length Lm. Therefore, a transmission delay time can be shortened to the minimum by dynamically optimizing the maximum packet length corresponding to the fluctuation of traffic amounts.
