Abstract: A control apparatus, which controls a drive motor that drives a rotor installed in an electrical aircraft, instructs the drive motor to selectively operate in at least two motor-control modes. The at least two motor-control modes include a flying motor-control mode for causing the electrical aircraft to fly, and a cleaning motor-control mode for cleaning the rotor. The control apparatus controls, in the cleaning motor-control mode, the drive motor such that a rotational frequency of the drive motor is lower than a predetermined human-audible frequency range.

Abstract: The present invention provides a method that enables the use of an aqueous solution of a copolymer of vinyl alcohol and an alkali metal neutralized product of ethylenically unsaturated carboxylic acid or carboxymethyl cellulose or a salt thereof, as a binder for secondary batteries, without causing a significant viscosity increase even if stored in the state of an aqueous solution. More specifically, the present invention provides a composition in the form of an aqueous solution containing a copolymer of vinyl alcohol and an alkali metal neutralized product of ethylenically unsaturated carboxylic acid and/or carboxymethyl cellulose or a salt thereof, wherein when the viscosity of the composition after being diluted with water (25° C. or less) to a viscosity of 200±100 mPa·s at room temperature (25° C.) and being adjusted to a temperature of 25° C. is defined as Xa1 (Pa·s), and the viscosity of the composition after being placed in an airtight container and being allowed to stand at 95° C.

Abstract: A battery separator 100 of one aspect of the present invention includes a sheet-shaped or film-shaped porous substrate 20 and an aliphatic polycarbonate containing layer 10 covering one surface or both surfaces of the substrate 20. According to this battery separator, since the aliphatic polycarbonate containing layer 10 covering one surface or both surfaces of the substrate 20 is provided, it is possible to reliably prevent or suppress deterioration of battery characteristics due to at least overdischarge. In addition, since the substrate 20 constitutes the battery separator 100 together with the aliphatic polycarbonate containing layer 10, the mechanical strength as a battery separator can be improved.

Abstract: A registration apparatus includes a scanner configured to optically read a product code from a product, a communication interface configured to communicate with one or more payment apparatuses associated with the registration apparatus, a display, and a processor.
