摘要： An aluminum alloy sheet excellent in terms of formability and bake hardenability is provided. The aluminum alloy sheet contains, in terms of mass %, Mg: 0.2 to 2.0%, Si: 0.3 to 2.0% and Sn: 0.005 to 0.3%, with the remainder being Al and unavoidable impurities. A differential scanning calorimetry curve of the aluminum alloy sheet has an endothermic peak in a temperature range of 150 to 230° C. and an exothermic peak in a temperature range of 240 to 255° C. The endothermic peak corresponds to a dissolution of a Mg—Si cluster and has a peak height of 8 μW/mg or less, including 0 μW/mg. The exothermic peak corresponds to a formation of a Mg—Si cluster and has a peak height of 20 μW/mg or larger.

摘要： An electrically conductive material for a connection component is disclosed. The electrically conductive material includes a Cu—Sn alloy coating layer 5 in which a Cu content is 55 to 70 at % and has an average thickness of 0.1 to 3.0 μm, and a Sn coating layer 6 having an average thickness of 0.2 to 5.0 μm, which are formed in this order on a surface of a base material made of a copper or copper alloy sheet strip. When a reflected electron image of a material surface is observed with a scanning electron microscope at a magnification of 100 times, a region A and a region B having a higher brightness than the region A and in which the Cu—Sn alloy coating layer is not exposed coexist on the material surface, and an area ratio of the region A on the material surface is 2 to 65%.

摘要： A compressed air energy storage and power generation device comprises a motor, a compressor, a pressure accumulation tank, an expander, and a generator. The motor is driven by a fluctuating input power. The compressor is mechanically connected to the motor and compresses air. The pressure accumulation tank is fluidly connected to the compressor and stores air compressed by the compressor. The expander is fluidly connected to the pressure accumulation tank and is driven by compressed air supplied from the pressure accumulation tank. The generator is mechanically connected to the expander and generates power to be supplied to a user. A cooling water flow path, whereby water flows inside a cooling water pipe for cooling air that is a working fluid, is provided inside a casing of the compressor. As a result, a compressed air energy storage and power generation device can be provided that is capable of efficiently reducing compressive axial force and of reducing power consumption.

摘要： An electrically driven winch device includes a winch drum, a plurality of axial-gap electric motors, and a drive shaft. The winch drum rotates around a drum axis in order to wind or unwind a work rope. The plurality of electric motors are electric motors configured to drive the winch drum to rotate, and are each provided with a stator, and rotors which rotate around a rotation axis and are disposed at an axial distance from the stator. The drive shaft is disposed coaxially with the drum axis and serially connects the rotors of the plurality of electric motors on the rotation axis.

摘要： A first determination unit performs a process (first process) of sequentially dividing an intensity value constituting first data by a reference intensity value to calculate an intensity ratio and determining whether the intensity ratio exceeds a first threshold (steps S3 and S4). When a predetermined period has elapsed, a second determination unit calculates an average change rate of the first data in the predetermined period to determine whether the average change rate is within a predetermined range (steps S9 and S10). When it is determined that the average change rate is within the range, the reference intensity value is updated and lowered (step S11). When the reference intensity value is updated, the first determination unit performs the first process by using the updated reference intensity value in the next predetermined period.

摘要： Provided is a 5xxx aluminum alloy sheet for forming, which sheet has low elongation anisotropy (in-plane anisotropy) and excellent press formability while having strength maintained at high level. This aluminum alloy sheet is an Al—Mg alloy sheet having a specific chemical composition. In the texture of the sheet, the orientation densities of Brass orientation and S orientation relative to a random orientation are controlled and minimized, where the orientation densities are expressed by orientation distribution functions. This allows the aluminum alloy sheet to have lower elongation anisotropy to thereby have better press formability.
