    Abstract: To improve tranquility and controllability of an iron core-equipped permanent magnet motor with an improved maximum energy product (BH)max by improving shape compatibility of a radial anisotropic magnet, there is provided a radial anisotropic magnet manufacturing method of fixing magnet powder in a net shape so as to maintain a magnetic anisotropic (C-axis) angle of a magnet with respect to a tangential line and for performing a deformation with a flow so as to have a predetermined circular arc shape or a predetermined annular shape. Particularly, by performing a deformation with a viscous flow or an extension flow, a deformability of the magnet is improved, and thus shape compatibility with respect to a thickness is. improved. A C-axis angle ? with respect to a tangential direction is controlled at an arbitrary position and an arbitrary angle so as to reduce cogging torque without separating a magnetic pole into segments.

  • Publication number: 20110147147
    Abstract: The flow of hydraulic fluid induced by sliding movement of a piston in a cylinder is controlled by a pilot-type main valve and a pilot valve to generate damping force. The valve opening of the main valve is controlled by adjusting the pressure in a pilot chamber through the pilot valve. A volume compensating chamber is defined by a flexible disk member so as to face the pilot chamber. The volume compensating chamber is communicated with a reservoir through communicating passages. When the disk valve opens, the volumetric capacity of the pilot chamber reduces. At this time, the flexible disk member deflects toward the volume compensating chamber, thereby suppressing an excessive rise in pressure in the pilot chamber and preventing an unstable operation of the pilot valve and the main valve to obtain a stable damping force.

    Abstract: In an ECU, a coolant fan performs cooling operation such that a control DUTY value is limited by a control DUTY value according to tolerable noise level of the cooling fan based on a vehicle speed in a case in which the temperature in the high-voltage battery is lower than a predetermined limitation for highest temperature. In a case in which the temperature in the high-voltage battery is higher than the predetermined limitation for highest temperature, the cooling fan performs the cooling operation by using an energy storage device cooling operation requirement value and an IPU cooling operation requirement value such that performance in the high-voltage battery is not affected. By doing this, a temperature controlling apparatus for batteries in which it is possible to cool the battery and solve temperature difference among a plurality of batteries can be provided.

  • Publication number: 20110073424
    Abstract: The flow of hydraulic fluid induced by sliding movement of a piston in a cylinder is controlled by a pilot-type main valve and a pilot valve, which is a pressure control valve, thereby generating damping force. By thrust from a solenoid actuator, the valve-opening pressure of the pilot valve is controlled, and the pressure in a pilot chamber is also controlled to control the valve-opening pressure of the main valve. When there is a failure, a valve body of the pilot valve is retracted to abut against a fail-safe disk by spring force of a valve spring. Thus, damping force is generated by the fail-safe disk at the downstream side of the pilot valve, and the valve-opening pressure of the main valve is also controlled by the fail-safe disk to obtain an appropriate damping force.
