Abstract:
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.
Abstract:
A rolled copper or copper alloy foil having a roughened surface formed of fine copper particles is obtained by subjecting a rolled 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 temperature of 20 to 50° C. and current density of 10 to 100 A/dm2. 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.
Abstract:
A holding mechanism 10 for holding an ink ribbon 20 includes a transparent shell 11 and a board 12. The transparent shell 11 of the ink ribbon 20 is provided with wind slack preventive portions 11a to 11d which prevent rotations of a feed bobbin 21 and reel bobbin 22, and wind meandering preventive portions 11e, 11f which bears down an axial end 23a of a film 23. The ink ribbon 20 can be stably held by the holding mechanism 10 during a transportation and a loading thereof. The transparent shell 11 is provided with support portions 11g, 11f which improve a stability when loading.

Additionally provided is a method of roughening the rolled copper or copper alloy foil.
Abstract:
An object of the present invention is to provide a reflection film formation technology which achieves the simplification of an apparatus structure and the cost reduction thereof. A film forming method of the present invention includes a reflection film formation step (P2) for forming a reflection film having light reflecting properties by vapor deposition onto an object to be film-formed, while introducing air into a film forming region; a polymer film formation step (P3) for forming a water-repelling polymer film on the reflection film; and a hydrophilized treatment step (P5) for performing a hydrophilized treatment by a plasma onto the water-repelling polymer film, while introducing air into the film forming region. According to the present invention, formation of the reflection film and the hydrophilized treatment of the polymer film can be performed without using argon gas.

Abstract:
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.
Abstract:
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.
