摘要： A noise-cut filter having distributed inductances and distributed capacitances is provided wherein conductive spiral coil patterns are formed on the opposite surfaces of a dielectric sheet, such that the spiral coil patterns are aligned with each other in a direction perpendicular to the plane of the dielectric sheet, and a main circuit pattern is constructed by bonding a main circuit conductor to the spiral coil pattern formed on one of the opposite surfaces of the dielectric sheet. The main circuit conductor is formed by stamping with a punch press so that the conductor has a cross sectional area large enough to allow the passage of current of a main circuit, and has substantially the same shape as the spiral coil pattern. Further, a grounding wire is bonded to the spiral coil pattern formed on the other surface of the dielectric sheet, so that the grounding wire leads the current involving noises which flows from the main circuit pattern into the spiral coil pattern via the dielectric sheet, to a ground terminal.

摘要： When an induction motor is variable-speed-controlled via an electric power converting circuit, the magnetic flux of the induction motor is modulated by adding an alternating current signal to, for example, a magnetizing current command. For example, the component depending on the slip frequency of the induction motor is extracted by an extracting means from at least one of the amounts of changes of the voltage, the electric current, and the magnetic flux, which are caused by the modulation of the magnetic flux. The amount of the voltage or the electric current supplied to the motor, etc. is controlled based on the extracted component via an adjusting unit and a control means, thereby implementing superior control of the induction motor.

摘要： A memory management unit for an information processing system includes a controller and a non-volatile memory. The controller controls data writing process. The non-volatile memory, used for storing non-rewritable and rewritable data, is partitioned into a read-only partition to store the non-rewritable data, and a rewritable partition to store the rewritable data including apparatus-specific data including access-restricted data required for activating the information processing system. The access-restricted data is prohibited from being written during normal usage but writable at specific times. The non-rewritable data, stored in the read-only partition, is protected from an abrupt power shutdown occurring when a data writing process is conducted to the rewritable data. The controller stores the access-restricted data to the read-only partition by changing an attribute of the read-only partition of the non-volatile memory from a read-only attribute to a rewritable attribute.
