  • Publication number: 20220090239
    Abstract: A grain-oriented electrical steel sheet is a grain-oriented electrical steel sheet which does not have an inorganic coating containing forsterite as a main component and which includes: a base steel sheet containing a prescribed chemical component; a silicon-containing oxide layer provided on the base steel sheet; an iron-based oxide layer provided on the silicon-containing oxide layer; and a tension-insulation coating provided on the iron-based oxide layer, having a thickness of 1 to 3 ?m, and containing phosphate and colloidal silica as main components. When the tension-insulation coating undergoes elemental analysis using a glow discharge optical emission spectrometry in a sheet thickness direction from a surface of the tension-insulation coating, a peak Si emission intensity satisfies a prescribed requirement.

    Abstract: A motorcycle includes a fuel tank, a vehicle body frame, a pair of front forks, and a canister. The fuel tank contains gasoline therein. The vehicle body frame supports the fuel tank. The pair of front forks are placed spaced apart from each other in a vehicle width direction to support a front wheel from both sides in the vehicle width direction such that the front wheel is rotatable, and mounted to the vehicle body frame such that the pair of front forks are rotatable around a head pipe. The canister adsorbs gasoline contained in a gasoline vapor present inside the fuel tank and supplies the gasoline to an engine. The canister is placed inward in the vehicle width direction relative to the pair of front forks when viewed from a front, and in front of an engine when viewed from a side.

    Abstract: A rotation position detection device includes a change drum, a magnetic field generator, and a magnetic field detector. The magnetic field generator is fixed to the change drum and rotates along with the change drum to differentiate an ambient magnetic field. The magnetic field detector is formed separately from the magnetic field generator and fixed to a position at which a magnetic field changes in response to rotation of the magnetic field generator so as to detect the magnetic field and output a signal that depends on the rotational position of the change drum on the basis of the detection result.
