InactiveUS20070180945A1Keep for a long timeReduce impact timeToothed gearingsSteering columnsEngineeringControl theory
When a column 4 reaches a tilting ascent end, the lower end 732 of a nut 73 abuts on the buffering segment 83 of a buffer 82. Thus, while the buffering segment 83 of the buffer 82 is elastically deformed, the nut 73 stops with no impact. Accordingly, the inertia when the nut 73 stops is restrained and the tightening torque of the nut 73 when the nut 73 stops is also restrained. For this reason, when an electric motor 61 is rotationally driven in a reverse direction, a feeding screw shaft 71 rotates in the reverse direction with the normal rotation torque of the electric motor 61. Thus, the nut 73 is caused to ascend in the axial direction along the screw segment of the feeding screw shaft 71 so that the column 4 can be tiltingly moved downward.

The embodiment of the invention provides a data transmission method and a data transmission system for a PCI-E (Peripheral Component Interface Express). The method can comprise the following steps of: judging whether a slave device is in an off-line state or not to obtain a first judging result; when the first judging result shows that the slave device is in the off-line state, judging whether the slave device responds to instructions of a master device or not to obtain a second judging result; and when the second judging result shows that the slave device does not respond to the instructions of the master device, sending a first response instruction to the master device so that the master device stops waiting for the response instruction sent from the slave device, wherein the first response instruction shows that the slave device is not well prepared. When the method or the system provided by the embodiment of the invention is adopted, the off-line state of the slave device can be fed back to the master device in time; and the influence time of the hot plug process of the slave device on the data processing service is reduced, so that the robustness of a PCI-E interface in the hot plug process can be improved.
