    摘要： In order to control a controlled object (1), such as a vacuum cleaner or washing machine signals are derived from a single sensor (4 or 5), which measures a single property of the controlled object (1), and are the signals used by a characteristic amount sampling unit (8) to derive a plurality of control characteristics. These are then processed by a neural network (15) to derive a basic control signal. The characteristics, or further characteristics derived from a further sensor (4) and a local condition detector are analysed by a fuzzy logic system (16) and used to modify the basis control signal. In other arrangements, the fuzzy logic is applied (60A, 60B, 60C, 60D) to each characteristic before the characteristics are applied to the neural network (15). Because the calculation time needed by the neural network (15) is long, it is possible to detect (50) if one of the characteristics has a particular volume (is within a predetermined range). Then, a fixed pattern may be derived, modified only by the fuzzy logic (16).

    摘要： In a vacuum cleaner, both static pressure H data and a variation width ΔH in the static pressure appearing when a suction port is operated are detected from a pressure sensor (8) provided at a rear side of a filter (7) within a main body (2) of the vacuum cleaner; a current variation width Δpbi appearing when the suction port is operated is detected from a current of a nozzel motor (26) for driving a rotary brush (10) stored in a power brush suction port; an air quantity at the suction port is calculated from the current, rotational speed of a fan motor (FM) and static pressure ; command values are newly obtained by performing a fuzzy calculation with the variation width Apbi, static-pressure command value Hcmd ; the variation width ΔH and the static-pressure command value Qcmd ; the variation width Δpbi and static-pressure command value Hcmd ; and also the variation width ΔH and static-pressure command value Qcmd as the input thereto ; the rotational speeds of the fan motor (FM) and nozzel motor (26) are controlled from the result of the command values ; and further optimum air suction force is automatically obtained, depending upon the suction port under use and cleaning floor plane.

    摘要： A permanent magnet type rotor is disclosed which comprises a cylindrical core member (4), a plurality of arcuate permanent magnet segments (3) disposed around an outer periphery of the core member (4) and a non-magnetic sleeve (2) disposed around outer peripheries of the arcuate permanent magnet segments. The magnet segments (3) having the same pole are brought into contact with each other. Circumferential direction pressing members (14) are interposed between the magnet segments having the different poles. It is thus possible to enhance the arrangement precision of the magnet segments (3) and a balance precision during the rotation to thereby stabilize the magnetic distribution characteristics.

    摘要： A controlling apparatus (10) controls a suction per­formance of a blower motor (2) which is installed into a main body (3) of a cleaner (1). The controlling apparatus (10) increases the suction performance when a suction nozzle is operated and decreases the suction performance when the suction nozzle is stopped. Corresponding to a floor cleaning suction nozzle and a crevice cleaning suc­tion nozzle, at a predetermined air flow amount range, the most suitable operation control is carried out automati­cally in accordance with the detected kind of suction nozzle. Whe the suction nozzle is exchanged the flow amount range is changed over and selected in accordance with the respective suction nozzle. A brushless direct motor is used as the blower motor and has an operational range by means of chopper control duty factor of 100 %.
