Title: Buffer mechanism for actuator
Inventor: YAMAMOTO FUTOSHI
IPC: F16F9/02
Filed: 1995-12-05
Abstract: PROBLEM TO BE SOLVED: To support the inertial load generated during the operation by providing a connecting member engaging with a rod and a table, and providing a pressure receiving member energized in the forward direction by the air pressure and displaced by the prescribed distance in the axial direction against the rod. SOLUTION: A diaphragm 21 made of a rubbery elastic material as a pressure receiving member is airtightly pinched between a connecting member 13 engaging with a rod 12 and a table and a cover 19. The space surrounded by the connecting member 13 and the diaphragm 21 is an airtight chamber 22, and compressed air is fed to the chamber 22. When the inertial load generated during the operation of a robot is applied, the pressure of the fed compressed air is set high in advance to make the pressing force of the diaphragm 21 strong so that the rigid state of a buffer mechanism 14 is maintained after the inertial load is applied. If the inertial load exceeds the set load when a piston 4 is moved to the left, the diaphragm 21 is pushed and displaced, and the compressed air in the chamber 22 exerts a spring action. The buffer action is exerted when necessary.

IPC: H04L69/40
Filed: 1996-12-19
Abstract: PROBLEM TO BE SOLVED: To improve probability that communication is established in resending by resending through a system that is different from the communication system which did not previously establish communication at the time of resending. SOLUTION: An NCU 4 and a modem 5 are connected to a CPU 1. Although the modem 5 initially decides a communication speed according to V.8 communication procedure, it basically precedes V.34 communication procedure which is full-duplex communication in that case and when it is not available, it uses, e.g. V.17 communication procedure which has a lower capability and is half- duplex communication. The CPU 1 decides whether full-duplex communication according to the V.34 communication procedure is performed or half-duplex communication according to the V.17 communication procedure is performed. The CPU 1 makes the modem 5 preferentially carry out transmission through the full-duplex communication system, and to resend it through the half-duplex communication system when communication is not established due to a communication failure.
