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: An in-vehicle electronic control unit includes a circuit board equipped with a coil and a power supply circuit, a resin member covering the circuit board, and a metal bracket fixed to the resin member for attaching the circuit board to a vehicle. The metal bracket includes a first shield portion and a second shield portion. The first shield portion is arranged to only a part of an upper surface of the resin member so that when projected in a winding axis direction of the coil, the first shield portion overlaps at least a part of the coil. The second shield portion extends from the first shield portion in the winding axis direction of the coil and is arranged to only a part of a side surface of the resin member.

Abstract: An electronic control device includes a substrate, a plurality of component-mounted wires disposed on the substrate, a plurality of electronic components mounted on the respective component-mounted wires, a common wire coupled with each of the electronic components, an interrupt wire coupled between one of the component-mounted wires and the common wire, and a heat release portion. The interrupt wire melts in accordance with heat generated by an overcurrent. The heat release portion is attached to the common wire and is disposed at a position where a wiring distance from the interrupt wire is shorter than a wiring distance between the interrupt wire and any of the electronic components except for one of the electronic components mounted on the one of the component-mounted wires.

Abstract: Novel regenerated cellulose fiber dyeable with disperse dye is disclosed. In this regenerated cellulose fiber, 10 to 40 weight % of polyester fine particles or styrene-acrylic polymer fine particles having an average particle size of 0.05 to 5 .mu.m are compounded. Products wherein the regenerated cellulose fiber and polyester fiber are used in combination can give dyed products excellent in homochromatic properties, and since both fibers can be dyed at the same time, the dyeing efficiency is remarkably improved.

Abstract: A sensor 13 is inserted into a connector 14. A constant voltage required to obtain a response current is applied across the connector 14 by a voltage applying source 15 at timings required. A response current of the sensor 13 inserted into the connector 14 is converted into a voltage by a current-to-voltage converter 16, and the amount thereof is determined by a microcomputer, the analysis results being displayed onto a display unit.
