摘要： In order to detect accurately a seating of clamped body and a clamping force at a seating, the workpiece supporting device has plural seating mechanisms 40. Each of the seating mechanisms 40 includes a load sensing element 45 receiving a clamping force or a fixing force. The load sensing element 45 consists of a material having a characteristic that said load sensing element is not substantially deformed by an applied load, especially it consists of a composite material dispersing a material having a pressure resistance effect or a magnetic resistance effect in a matrix of an electric insulation ceramics material. An abnormal clamping or fixing of the clamped body and an abnormal overload are detected by detecting an output from plural load sensing elements 45 supporting the clamped body.

摘要： A CPU computes a throttle opening degree increasing speed Vθh and a steering wheel angular velocity Vθ based on a throttle opening degree θh and a steering wheel angle θ. Based on the throttle increasing speed Vθh and the steering wheel angular velocity Vθ, the CPU selects one of a first drive mode and a second drive mode. The CPU controls the power transmission ratio of a power transmitting device according to the selected drive mode. Therefore, the power transmission ratio of the power transmitting device is properly controlled in accordance with the degree of intention for acceleration of the driver, which is computed based on the throttle increasing speed Vθh, and the turning speed of the steering wheel, which is computed based on the steering wheel angular velocity Vθ. Therefore, the drive mode is properly switched in accordance with the driving state of a four-wheel drive vehicle.

摘要： An improved steering control apparatus is provided, wherein a driver can easily operate a steering wheel while the automatic steering mode is active so as to steer the vehicle in coping with any situation. The steering control system 41 that is provided in the steering control apparatus can determine whether a driver operates a steering wheel 33 by checking whether the electric current command value I1 for the assist control is more than a predetermined threshold value K1 while the automatic steering mode is active. And, as the operation of the steering wheel 33 is given precedence to continuation of the automatic steering control in determining whether the steering control apparatus 11 is changed from the automatic steering mode to the manual steering mode, the driver can easily rotate the steering wheel 33 in a state where the electric motor 19 generates enough assist force.

摘要： An electric steering control device is provided which is capable of enabling the driver to perform steering manipulation stably without being substantially affected by the ambient temperature and the heat generation of the control device. The control device comprises a temperature sensor for detecting the temperature of a circuit board mounting a motor drive circuit thereon and a compensation section for compensating an electric current command value based on the board temperature detected by the temperature sensor, so that en electric motor for exerting an assist force on a vehicle steering mechanism is driven by the compensated electric current command value output from a motor drive circuit. Therefore, the steering operation can be done stably without being substantially affected by the ambient temperature and the heat generation of the control device. In particular, since the temperature sensor is arranged not on the motor drive circuit per se but on a circuit board mounting the motor drive circuit thereon, the freedom can be heightened in arranging the temperature sensor. Further, since the temperature sensor for heat control of a spiral cable provided on the electric motor is utilized also for compensation of the electric current command value, the components for the control device can be reduced in number.

摘要： A variable reluctance-type resolver which does not deteriorate detecting accuracy, and which can fix the rotor to the rotate shaft cheaply is comprised of a stator 5 on which coils 6 are wound, a rotor provided with protrude poles 4a and an annular stopper 10 made of magnetic material. An outer diameter DS of the stopper 10 is selected to be smaller than a valley diameter DR of the rotor 4.

摘要： It is one object of a grinding machine and a grinding fluid supply-nozzle therefor according to the present invention to supply grinding fluid to a moving grinding point reliably, even if the surfaces of a grinding wheel is abraded up.A wheel head 5 advances/retracts to a workpiece. A grinding wheel G is carried rotatably by the wheel head 5 and grinds an eccentric portion W of the workpiece. A grinding fluid supply-nozzle 50 supplies grinding fluid to a moving grinding point K where the grinding wheel G contacts the eccentric portion W of the workpiece. The grinding fluid supply-nozzle 50 is made from a curve portion 53, an opening 51 and a straight portion 52 between the curve portion 53 and the opening 51. The grinding fluid supply-nozzle 50 spouts the grinding fluid to a grinding fluid supply point Pc upstream the grinding points K and Ks, even in the case that the grinding wheel G has been abraded up. Besides, the angle between the tangent of the grinding fluid supply point Pc and the grinding fluid spouted from the grinding fluid supply-nozzle 50 is smaller than a right angle.

摘要： In a pressure sensor which has a metal housing 12 containing a sensor chip 11 and a joint housing 14 and in which an insulating member 15 is arranged to electrically insulate both of the metal housing 12 and the joint housing 14 from each other, the metal housing 12 is connected to a stable potential such as, for example, a sensor power supply or a sensor ground. Thus, there can be solved a problem that the detection signal is liable to be influenced by electric noise from outside where a signal line of the pressure sensor and the sensor housing are electrically suspended or unfixed.

摘要： A booster includes a booster circuit and a microcomputer. The booster circuit outputs an output voltage. The output voltage is obtained by boosting a power supply voltage. The microcomputer controls the output voltage through a feedback control based on the deviation of the output voltage from a target voltage. The microcomputer determines whether the booster is in an initial state based on a start signal or a restart signal. When determining that the booster is in the initial state, the microcomputer corrects the target voltage such that the target voltage gradually increases from the power supply voltage as time elapses until a predetermined period elapses from the start of the initial state.

摘要： The invention provides an electric power steering apparatus which can improve a steering feeling. In the electric power steering apparatus, in the case that once the electric abnormality is generated in the hardware such as the motor, the torque sensor or the like and an output of the assist force by the motor is reduced, however, the electric abnormality is thereafter dissolved due to some kind or another reason, the output of the assist force by the motor is increased immediately to an intermediate target value (within a broken line α). Accordingly, it is possible to prevent such a steering feeling as the steering wheel becomes suddenly heavy. Further, since the output of the assist force is gradually increased to a reset target value (within a broken line β) after the output of the assist force by the motor is increased to the intermediate target value, it is possible to prevent such a steering feeling as the steering wheel becomes suddenly light on the basis of the thereafter increase of the assist force even if the steering wheel becomes heavy to some extent. Accordingly, it is possible to smoothly change to the assist at a normal time from the assist at an abnormal time while preventing the steering ineffective feeling, and it is possible to improve the steering feeling.
摘要翻译：本发明提供一种能够提高转向感的电动助力转向装置。在电动助力转向装置中，在电动机，扭矩传感器等的硬件中产生电动异常和电动机的辅助力的输出一旦减少的情况下，电气异常是此后由于某种或其他原因而溶解，马达的辅助力的输出立即增加到中间目标值（在虚线α内）。因此，可以防止方向盘突然变重的转向感觉。此外，由于在马达的辅助力的输出增加到中间目标值之后，辅助力的输出逐渐增加到复位目标值（在虚线β内），所以可以防止这种转向即使方向盘在一定程度上变重的情况下，随着辅助力的增加也随着方向盘突然变亮。因此，能够在防止转向无效感的同时在异常时的辅助下正常地顺利地变更为助力，能够提高转向感。
