Abstract: A method for producing a hot-rolled steel sheet which enables predicting a temperature history of unevenness of the end face of a coil includes: measuring a surface temperature of hot-rolled strip-shaped steel; calculating a temperature history in a natural cooling state after coiling, assuming that the strip-shaped steel has been coiled without unevenness on an end face, based on the surface temperature measured in the measurement step; actually coiling the strip-shaped steel after the measurement step; scanning with a displacement meter, an end face of a coil formed in the coiling step, and deriving a size of the unevenness of the end face over a radius of the coil; and predicting a temperature history of the unevenness in a natural cooling state using: the temperature history calculated in the first calculation step; and the size of the unevenness derived in the derivation step.

Abstract: A mudguard member for a saddled vehicle covering above a rear wheel, a rear fender as a mudguard member is formed from fiber-reinforced resin. The rear fender has a surface provided with a resin-made reinforcing rib, the surface facing toward the rear wheel. The rear fender is formed in an elongated shape including: a vehicle attached portion that is arranged at a vehicle-front-side; and a length extension portion that extends from the vehicle attached portion toward the rear of the vehicle body. The length extension portion has a top panel and side panels that extend obliquely downward from both vehicle-widthwise sides of the top panel. The reinforcing rib includes: longitudinal ribs that extend from the vehicle attached portion to a vehicle-longitudinal center of the length extension portion; and transverse ribs that are arranged in a grip pattern in conjunction with the longitudinal ribs.

Abstract: A fiber reinforced resin product includes at least one layer of a first fiber reinforced resin layer in which first reinforcing fibers having a large breaking elongation are contained in a layered form, and at least one layer of a second fiber reinforced resin layer in which second reinforcing fibers having a smaller breaking elongation and a larger tensile strength in comparison with those of the first fiber reinforced resin layer are contained in a layered form. The second fiber reinforced resin layer is positioned outwardly of the first fiber reinforced resin layer. Furthermore, the first fiber reinforced resin layer and the second fiber reinforced resin layer share a single matrix resin in common.

Abstract: Particles contained in a suspension are separated in accordance with their magnetic susceptibility and based on the variation in flow velocity of suspension. In order to achieve this magnetic separation, a pair of wall plates having at least one flat surface in which a plurality of ferromagnetic narrow wires are buried in parallel are positioned in parallel to each other with a small distance therebetween so that the flat surfaces are opposed to each other to form a channel. The suspension flows in a laminar state with different flow velocities through the channel in the longitudinal direction of the ferromagnetic wires. A magnetic field is externally applied to the channel in the direction perpendicular both to the flow direction and the wall plates. Particles are separated in accordance with their magnetic susceptibility and based on variation in flow velocity which interacts with the magnetic susceptibility.
