摘要:
A multilayer capacitor includes a capacitor body in which internal electrodes in a first internal electrode group are overlapped with internal electrodes in a second internal electrode group with dielectric layers sandwiched therebetween. A first external electrode has a first wraparound portion and a second wraparound portion, and a second external electrode has a third wraparound portion and a fourth wraparound portion. The volume proportions of the effective layers in a first area sandwiched between the first wraparound portion and the second wraparound portion and in a third area sandwiched between the third wraparound portion and the fourth wraparound portion are set to at least about 10%. The volume proportions of the effective layers in a second area toward a lower surface in the first area and in a fourth area toward the lower surface in the third area are set to about 15% or less. The external dimensions of the multilayer capacitor 1 are about 1.6±0.1 mm in length by about 0.8±0.1 mm in width by about 0.8±0.1 mm in thickness.

The “squeal” that occurs when an electric field is applied to a multilayer ceramic capacitor mounted on a substrate is suppressed by providing in an active part contributing to formation of capacitances between internal electrodes facing each other in a capacitor body, low-activity regions positioned near respective end edges of respective external electrodes. A facing area of the internal electrodes in the low-activity regions is less than or equal to one fifth that of the internal electrodes in a normal region having the same volume as that of the low-activity regions. This makes it possible to suppress occurrence of electric-field-induced distortion near the external electrodes bonded to a substrate and reduce the force that causes the substrate to bend.

A control apparatus for a multiphase AC electric motor having an inverter includes a current control including an abnormal-state current controller; an abnormal-state detector that detects an abnormal state of any of a wire of an electric motor, a wire of an inverter, and a wire connecting the electric motor to the inverter as an abnormal phase; and an abnormal phase disconnect. The abnormal phase disconnect disconnects one or more of phases detected to be in an abnormal-state and the abnormal-state current controller generates an abnormal state voltage command in accordance with detection of an abnormal state, and uses phases other than the disconnected phases of the inverter to control individual currents of the phases, with the abnormal-state voltage command used as a multiphase voltage command.

A dielectric ceramic contains a barium titanate compound oxide as a main component; at least one rare earth element R selected from Y, La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, and Lu; Mg; and Ni, such that a crystalline compound oxide containing the rare earth element R, Ni, and Ti as main components is present. Dielectric ceramic layers are made of the dielectric ceramic. Accordingly, even when a higher electric field is continuously applied under a high-temperature atmosphere for a long time, high reliability can be ensured.

A control apparatus for an electric motor, in which a current controller giving multiphase voltage commands to a drive circuit for an inverter includes a normal-mode current controller for use in a normal mode, an abnormal-mode current controller for use in an abnormal mode, and an abnormality decision device. In a case of an abnormality occurring to one phase of an electric motor or the inverter, the controller is altered, and the abnormal-mode multiphase voltage commands which are generated by the abnormal-mode current controller are set as the multiphase voltage commands for the inverter drive circuit.

A ceramic base body includes primary phase particles containing a CaZrO3-based compound as a primary component and secondary phase particles containing at least Mn, and internal electrodes are primarily composed of Cu. There are about 2 parts by mole or more of Mn and about 0.69 parts by mole or more of Si pph by mole of primary component, are contained in the ceramic base body, and the area ratio of the secondary phase particles on a cross-section of the ceramic base body is about 0.1% or more. Of those secondary phase particles having a particle diameter of about 0.1 μm or more, about 67% or more (preferably about 85% or more) contains Cu and Si. A multilayer ceramic capacitor containing the ceramic base body can be manufactured by performing a heat treatment at a temperature of about 700° C. or more in a reducing atmosphere at an oxygen partial pressure of about 10−8.5 MPa or less after the formation of external electrodes. As a result, a highly reliable multilayer ceramic capacitor can be realized in which the temperature properties of electrostatic capacitance are superior, a high Q value is obtained, and the degradation in high-temperature load lifetime can be suppressed.
摘要:
In the control of an electric power steering apparatus, where so-called lead steering control is performed in which a steering wheel angle signal is output through a lead filter to correct reaction delay of a driver and a vehicle, a delay in control response occurs due to feedback of a road surface reaction force torque. When road surface reaction force torque is fed back to the steering wheel, it is added through a low-pass filter having a time constant equal to a reaction delay time constant of a driver. A sum signal is output through a lead filter to a second motor for controlling a steering shaft.
