Title: Output circuit
Inventor: HAYASHI TAKAAKI
IPC: H03K17/16
Filed: 1988-04-13
Abstract: PURPOSE:To obtain an output circuit with small overshoot or undershoot which occur at the time of output and with small radiation noise by controlling signals driving the gates of P type and N type MOSFETs in a final stage. CONSTITUTION:In an initial state, a data signal phi1 in a control circuit 3 is in L, the P type MOSFET1 in a final stage output inverter is turned off, the N type MOSFET2 is turned on and an output signal phi5 is in L. When the signal phi1 changes from L to H, the driving signal phi2 gradually changes from H to L, and the driving signal phi3 sharply changes from H to L. Since FET1 is gradually turned on, the waveform of the signal phi5 gradually rises from L to H, but a time when FETs 1 and 2 simultaneously turned on is short and a through current is small since FET2 is sharply turned off. When the signal phi1 changes from H to L, the signal phi2 sharply changes from L to H, and the signal phi3 gradually changes from L to H. Thus, FET2 is gradually turned on, and the signal phi5 gradually changes from H to L, but the through current is small since FET 1 is sharply turned off.

Abstract: PROBLEM TO BE SOLVED: To prevent an internal optical fiber from being deflected by a deflection suppressing material when encapsulated in the assembly of the optical connector structured by assembling and integrating a ferrule part having the optical fiber inside and a mechanical splice part connecting the internal optical fiber and an inserted optical fiber to each other. SOLUTION: An optical connector 6A is constituted by forming a space part 21 for preventing an internal optical fiber 1 from abruptly curving owing to a position shift between an optical fiber hole 13 on the side of a ferrule part 5 and an alignment groove 10 on the side of a mechanical splice part 3 between the both. This space part 21 is filled with a deflection suppressing material 22, which is initially in a liquid or low-viscosity state and then cured thereafter enough to suppress the deflection of the internal optical fiber 1. The deflection suppressing material is in the liquid or low-viscosity grease state when encapsulated in the space part 21, so the internal optical fiber 1 is never deflected by the injected deflection suppressing material.
