Abstract: A controller of an electric car for controlling a motor which drives a wheel of the electric car by a vector control inverter for controlling the primary current of the motor which is divided into an exciting current component and a torque current component which are respectively controlled by the command values of the components, characterized in that the controller comprises a means which detects the wheel speed (including the rotor frequency of the motor which is proportional to the wheel speed), a means which detects slip and skid of the wheel in accordance with the differential coefficient (change rate with time) of the detected wheel speed, a means which detects the readhesion of the wheel in accordance with the differential coefficient and 2nd order differential coefficient of the detected wheel speed and a means which adjusts the torque current component command value in accordance with the detection results of both the detecting means. The readhesion point of the wheel can be found when the wheel slips or skids, and the torque current component of the motor can be restored in a short time accordingly by utilizing the high speed response of the vector control. Therefore, even in a state such as a rainy weather in which the adhesion factor is small, the torque can be efficiently utilized to a physical adhesion limit, so that the acceleration/deceleration of the electric car can be increased as high as possible.

Abstract: One or more memory-device-side processors which can access the memory device belong to one group. Common memories and cache memories are allotted to the respective groups. When the access to the memory device is requested by a host-side processor, the memory-device-side processor of the group to which the memory device belongs informs the host-side processor of the stored cache address or the cache address to be stored and the data length. The host-side processor reads data at the address or writes data into the address. Thus, the access neck of the common memory and the cache memory is reduced and the system throughput is improved.

Abstract: A semiconductor device manufacturing method wherein a metal film formed on a semiconductor wafer is polished by using an abrasive containing abrasive grain, an oxidizing agent, and an ammonium group-containing pH regulator, whereby the deterioration of a semiconductor element due to a defective form of the metal film and due to the abrasive components is prevented. Since an abrasive not containing metal ions which could cause the semiconductor element to be deteriorated is used, a washing step to be carried out after the polishing operation can be simplified.

Abstract: When an IRD (103) performs reservation operation to use a bus in order to transmit broadcasting data from the IRD (103) through the bus in a desired time zone, the IRD (103) inquires all the devices connected to the bus, such as DVD (104), D-VTRs (1101 and 102), a CAM (105), a TV (100), and an isochronous manager section (107) of the D-VTR (1101) of the information about the present bus using states and bus reservations states. The manager section (107) and the other devices give the IRD (103) answers to the inquiry. The IRD (103) judges the possibility of the reservation from the answers. Then the IRD (103) judges that the reservation is possible, performs reservations. When the IRD (103) judges that the reservation is impossible, the IRD (103) displays the reason on the TV (100). Therefore, the use of devices beyond the transfer capacity of the bus is prevented.

Abstract: An automatic on-delay compensation value regulator, and a low cost and high precision controller are provided. An on-delay compensation value calculator (35) is provided in a control circuit (3). The current of an AC motor (1) and the voltage of a power converter (2) are measured, and the carrier frequency is varied to calculate an on-delay compensation value. A Fourier converter is built in the on-delay compensation value calculator (35). The on-delay compensation value is varied so as to minimize the harmonics and ripples in the current to obtain a proper on-delay compensation value. As the deviation of the on-delay compensation value which is caused by the variation of the power converter itself can be controlled automatically, a torque ripple caused by the variation of the on-delay compensation value is prevented and a high precision controller is realized. Further, as the allowance of the variation of the hardware is increased, a low cost controller is realized.
