Abstract: A vehicle apparatus control device includes a state detection apparatus, a provision apparatus, and an optimization apparatus. The state detection apparatus detects a drive state of a driver of a vehicle. The provision apparatus, as a vehicle apparatus, provides information to the driver of the vehicle through one of five senses in a predetermined provision manner. The provision apparatus suggests to the driver that the drive state is out of the appropriate range. The optimization apparatus causes the provision apparatus to provide the information by changing the provision manner when the drive state of the driver detected by the state detection apparatus is out of an appropriate range.

Abstract: In cold-rolling a steel sheet coil, when a tail end portion of a steel sheet coil (7) is wound around a tension reel (3) prior to second-pass rolling after the completion of first-pass rolling, the tail end portion is heated to a temperature within a range of not lower than 50° C. nor higher 350° C. with a heater disposed between a rolling stand (1) and the coil tail end-side tension reel (3).

Abstract: A capacitance operation device includes an operation plate, an electrode, and an electrode film. The operation plate has an operation surface to be contact-operated by an operation body. The electrode outputs a detection signal according to a change in capacitance generated between the electrode and the operation body. The electrode film supports the electrode. The operation plate has a rear surface on a side opposite to the operation surface. The rear surface is formed with a groove. The groove is filled with an adhesive agent, and the electrode film is adhered to the operation plate with the adhesive agent.

Abstract: An inexpensive method with good productivity, without coating of titanium metal, is necessary for satisfying the requirement for a long life of a heavy-duty anticorrosive steel material and in order to provide a heavy-duty anticorrosive coated steel material with excellent resistance against separation and corrosion. To respond to this demand, an oxygen-blocking layer is incorporated into the heavy-duty anticorrosive coating, for example, an organic resin sheet (film) capable of blocking the oxygen permeation is stacked or such an organic resin is painted on a conventional heavy-duty anticorrosive coating or a heavy-duty anticorrosive coating subjected to a chemical conversion treatment as the surface treatment.
