A vehicle driving assist system has a controller configured to calculate a risk potential indicative of the degree of convergence between a host vehicle in which the system is installed and a preceding obstacle. Then, the controller performs a driver notification controlling operation that produces a driver notification stimulus based on the risk potential. Considering the acceleration of the preceding obstacle, the speed of the host vehicle, and the following distance between the host vehicle and the preceding obstacle, the controller calculates a threshold value for determining when to commence the control of the driver notification controlling operation.
摘要:
A vehicle driving assist system executes an actuation reaction force control of accelerator pedal, a driving force control or a braking force control in a manner that is appropriate in consideration of the traffic situation in which the vehicle is being driven. The vehicle driving assist system calculates a risk potential that indicates the degree of convergence between the vehicle and an obstacle existing in front of the vehicle based on a prescribed control pattern. Then, based on the risk potential, the accelerator pedal actuation reaction, the host vehicle driving force and/or the host vehicle braking force are controlled. The intent of the driver regarding acceleration and deceleration based on the actuation state of the accelerator pedal is preferably used in controlling one or all of the accelerator pedal actuation reaction, the host vehicle driving force and the host vehicle braking force.

Provided is a rolled copper or copper alloy foil having a roughened surface formed of fine copper particles, obtained by subjecting a rolled copper or copper alloy foil to roughening plating with a plating bath containing copper sulfate (Cu equivalent of 1 to 50 g/L), 1 to 150 g/L of sulfuric acid, and one or more additives selected among sodium octyl sulfate, sodium decyl sulfate, and sodium dodecyl sulfate under the conditions of a temperature of 20 to 50° C. and a current density of 10 to 100 A/dm2. The provided rolled copper or copper alloy foil subject to roughening is reduced in craters which are obvious defects unique to rolled copper or copper alloy foils having a roughened surface, has high strength, adhesive strength with the resin layer, acid resistance and anti-tin plating solution properties, high peel strength, favorable etching properties and gloss level, and also suits for use in producing a flexible printed wiring board capable of bearing a fine wiring pattern. Additionally provided is a method of roughening the rolled copper or copper alloy foil.

An automatic paper feeder comprises: a pick roller for picking out paper accommodated in a paper cassette; a separation roller to which a torque limiter is connected, and which separates the paper picked out by the pick roller to feed the paper one sheet at a time; means for moving the separation roller into contact with or away from the pick roller; a lifter for lifting the paper accommodated in the paper cassette to cause the paper to be moved into contact with or away from the pick roller; and means for driving the lifter. The means for moving the separation roller into contact with or away from the pick roller and the means for driving the lifter are realized by a single driving means.

A paper clamping mechanism for clamping a sheet of printing paper on a drum-shaped platen of a printer is disclosed. The mechanism comprises a clamp member radially slidably mounted at its legs to the end surfaces of the platen, and a lever pivotted to the frame of the printer. The clamp member comprises a pressor which opposes an axial recess on the peripheral surface of the platen; the front end portion of a sheet of paper is held between the pressor and the recess during the printing operation, the clamp member being urged toward the axis of the platen by a spring. The clamp member further comprises an axially extending pin formed on a leg thereof. The lever is urged by a spring to a position at which it is stopped by a pin formed on the frame of the printer. An arm of the lever comes into contact with the pin on the leg of the clamp member when the clamp member is rotated with the platen. When the arm of the lever comes into contact with the pin on the clamp member rotated in the printing direction, the lever turns and yields upon contact; when, on the other hand, the arm comes into contact with the pin on the clamp member rotated in the reverse direction, the pin slides on the arm of the lever which is stopped by the stopper pin, so that the clamp member is raised from the platen to form a gap between the pressor and the recess on the platen.

The foil has reduced craters, which are defects unique to rolled foils having a roughened surface, has high strength, adhesive strength with the resin layer, acid resistance and anti-tin plating solution properties, high peel strength, favorable etching properties and gloss level, and is suitable for producing a flexible printed wiring board capable of bearing a fine wiring pattern. A method of roughening the rolled foil is also provided.
