摘要： A DC dynamoelectric machine with interpoles (3) between field poles (2) operable in sparkless even under heavy operating conditions comprising magnetic flux bypassing members (10A, 10B) made of a solid soft iron, each bypassing member disposed between respective field poles (2) and interpoles (3) at their ends near the armature (6) with an air gap to the field pole (2) for controlling the interpole magnetic flux. The solid soft iron magnetic flux bypassing member (10A, 10B) suppresses sudden change of magnetic flux flowing therethrough by permitting flow of eddy current therethrough and maintains the interpole magnetic flux at a desired amount even during a sudden change of load current.

摘要： The rotor 2 of a rotating field type turbine generator is provided with slots 3 for accommodating the field windings, wedges 4 positioned at the portions of the magnetic poles on the rotor 2 for holding the field windings and wedges 5 positioned between the magnetic poles on the rotor. These wedges 4 and 5 are constituted by metal bars without joints to enhance damper effect thereby. Magnetomotive forces due to higher harmonics, which causes temperature rise of the rotor 2 and torque ripple during starting with thyristors, induces an elliptic rotating magnetic field having the longer diameter on d axis extending in the direction of magnetomotive force induced by the field windings and the shorter diameter on q axis perpendicular to d axis, and thus a larger eddy current is induced flowing along q axis on the rotor 2 than that flowing along d axis. Therefore the thickness d' in radial direction of the wedges 5 positioned between the magnetic poles on the rotor 2 is determined larger than the thickness d in radial direction of the wedges 4 positioned at the portions of the magnetic poles on the rotor 2 to reduce the resistance of the wedges 5 and to easily lead the eddy current flowing in the axial direction of the rotor 2, thereby a good thermal balance over the entire portions on the rotor 2 is achieved.

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： An output of an electric driven blower (2) in a cleaner main body (1) is controlled in response to a detection value of a pressure sensor (12) which detects an operation condition in the cleaner main body (1). A change-over level setting value (C₁ , C 1′ ) is provided as an control value for the sensor (12) so as to form a judgement point for changing over a control condition of the blower. A return level setting value (C R′ C 2′ ) is provided as a control value for the sensor so as to form a judgement point for returning to a previous control condition of the blower (2) from a changed-over condition of the blower. When the detection value of the sensor (12) is more than the change-over level setting value, the return level setting value is set higher than the change-over setting value, thereby the output of the blower (2) is increased, or the return level setting value is set a lower than the change-over level setting value, thereby the output of the blower is decreased.
摘要翻译：响应于检测到吸尘器主体（1）中的操作状况的压力传感器（12）的检测值，控制吸尘器主体（1）中的电动鼓风机（2）的输出。提供转换电平设定值（C1，C1min）作为传感器（12）的控制值，以便形成用于改变鼓风机的控制状态的判断点。提供返回水平设定值（CR min C2 min）作为传感器的控制值，以形成从鼓风机的转换状态返回到鼓风机（2）的先前控制状态的判断点。当传感器（12）的检测值大于转换电平设定值时，返回电平设定值被设定为高于转换设定值，由此鼓风机（2）的输出增加，或返回电平设定值被设定为低于转换电平设定值，从而降低鼓风机的输出。
