Abstract: Rectification is a process that converts electromagnetic fields into direct current (DC). Such a process underlies a wide range of technologies, including wireless communication, wireless charging, energy harvesting, and infrared detection. Existing rectifiers are mostly based on semiconductor diodes, with limited applicability to small voltages or high frequency inputs. Here, we present an alternative approach to current rectification that uses the electronic properties of quantum crystals without semiconductor junctions. We identify a new mechanism for rectification from skew scattering due to the chirality of itinerant electrons in time-reversal-invariant but inversion-breaking materials. Our calculations reveal large, tunable rectification effects in graphene multilayers and transition metal dichalcogenides. These effects can be used in high-frequency rectifiers by rational material design and quantum wavefunction engineering.

Abstract: In a first part made of a thermoplastic resin, a second part coated with the same resin is insert-molded. The applied resin of the second part and the resin of the first part melt together by heating during molding to thereby obtain firm bonding.

Abstract: A fuel supply module mounting structure for a fuel tank (1) is disclosed having a fuel tank module (6) comprised of a tilting mechanism (TM) disposed between an upper plate (5) and a case (8,30) and operative to cause the case to be tilted in a direction away from a valve (20) in response to vertically upward movement of the case in a value beyond a given amount of stroke upon abutting engagement of the case with a bottom wall portion (3) of the fuel tank, avoiding interference between the valve (20) and a pump (9) contained in the case (8,30).

Abstract: A non-return valve includes a main tube to be externally inserted into and joined to a fuel filling pipe, and a valve element to be provided on a downstream end of the main tube for allowing fuel to flow into a fuel tank and inhibiting a back flow out of the fuel tank. On an upstream side of the main tube, provided is a first inner tube including a first retaining portion relevant to the fuel filling pipe, an annular sealing member abutting on an inner periphery of the main tube and on an outer periphery of the fuel filling pipe, and a second inner pipe disposed more upstream than the first inner tube so as to sandwich the annular sealing member together with the first inner tube, the second inner tube including a second retaining portion relevant to the main tube.

Abstract: A refueling system is provided that can simplify the layout and decreases manufacturing cost by eliminating the vent valve and reducing the number of parts, while enabling easy refueling. A canister adsorbs and cleans fuel vapor generated inside a fuel tank and discharges the cleaned gas to the atmosphere through a canister drain cut valve. A sender unit is provided inside the fuel tank with a fuel level sensor that detects the amount of fuel inside the fuel tank. A controller closes the canister drain cut valve when a vehicle speed sensor detects that the vehicle is stopped and in the refueling condition and the fuel level detected by the fuel level sensor is at or above a first prescribed height.
