Abstract: A laser beam generation device includes power supply units, LD modules, a combiner, and a control device. The LD modules receive currents from the power supply units, and output laser beams. The combiner collects the laser beams and outputs one laser beam. The control device generates control signals such that power of the laser beam becomes a laser output setting value and such that the currents become current command values. Phases of pulses of the control signals are shifted from each other by 60 degrees.

Abstract: A coating liquid includes aluminum phosphate, a nonionic surfactant, and water and/or water-soluble solvent that dissolves or disperses the aluminum phosphate and the nonionic surfactant. An amount of the nonionic surfactant is preferably 1 vol % or more and 10 vol % or less. The nonionic surfactant is preferably at least one selected from the group consisting of ester, ether, alkylglycoside, octylphenol ethoxylate, pyrrolidone, and polyhydric alcohol. Applying such a coating liquid to a surface of a thermoelectric member, and drying and firing the coating liquid enables formation of a dense antioxidant film containing aluminum phosphate on the surface of the thermoelectric member.

Abstract: A control device of a vehicle with a stepped automatic transmission has: a gradient acquiring part; a driving force calculating part; a future change estimating part; and a shift control part.

Abstract: The present disclosure generally relates to a high-frequency oscillator for use in a recording device having a microwave-assisted magnetic recording head. The microwave-assisted magnetic recording head achieves a large assist effect by using an extended spin torque oscillator disposed between a main magnetic pole and a pole opposite the main magnetic pole. The spin torque oscillator obtains a strong high-frequency magnetic field and comprises a first non-magnetic spin scatterer, a reference layer, a first non-magnetic spin transfer layer, a first magnetic field generating layer, a second non-magnetic spin transfer layer, a second magnetic field generating layer, and a second non-magnetic spin scatterer. The spin torque oscillator has a drive current flowing though in the direction from the first magnetic field generating layer to the reference layer.

Abstract: Embodiments disclosed herein generally relate to a MAMR head. The MAMR head includes an STO and a current switching system electrically coupled to the STO. The current switching system can be used to optimize the STO frequency by changing the STO bias polarity, i.e., by changing the direction of the current flowing to the STO. As a result, the difference between the STO frequency and the magnetic media frequency is minimized, which improves recording capability of the MAMR head.
