摘要： To lighten the weight of an electromagnetic actuator and a valve-open-close mechanism by forming the stems from a lighter material than conventional. A pair of electromagnets formed of stators and coils are opposed to each other with a gap therebetween. An armature is disposed in the gap so as to be reciprocable between one electromagnet and the other electromagnet by the electromagnets. A first stem for transmitting the movement of the armature from one electromagnet toward the other electromagnet to a valve of the internal combustion engine is inserted in a guide hole formed in the stator of one electromagnet. The first stem is formed of a lighter material than the armature to lighten the weight of the electromagnetic actuator and a valve-open-close mechanism of an internal combustion engine.

摘要： In controlling the fluid pressure applied to a load using a proportional fluid pressure control valve (1) or a flow control valve (30) responsiveness of control is improved in a pressure region where the consumption of fluid is larger than in other regions. In this method, if there is a pressure region where the consumption of fluid is greater than in other regions, overshoot control is carried out to increase fluid pressure in such a pressure region by adding a predetermined pressure to a target pressure for a predetermined time, or undershoot control is carried out to reduce fluid pressure in such a pressure region by subtracting a predetermined pressure from a target pressure for a predetermined time. It is thus possible to increase and reduce fluid pressure quickly to a target pressure even in a pressure region where the consumption of fluid is large, and thus to improve responsiveness of control.
摘要翻译： 在使用比例流体压力控制阀（1）或流量控制阀（30）控制施加到负载的流体压力时，在流体消耗大于其它区域的压力区域中提高了控制的响应性。 在该方法中，如果存在流体的消耗量大于其他区域的压力区域，则通过在预定时间内对目标压力加上规定的压力，进行过冲控制，以增加这样的压力区域的流体压力， 或者进行下冲控制，以通过从目标压力减去预定压力达预定时间来减小这种压力区域中的流体压力。 因此，即使在流体消耗量大的压力区域中也可以将流体压力快速地增加并降低到目标压力，从而提高控制的响应性。

摘要： It is proposed to lessen the weight and improve the mechanical strength of a retainer of a valve openclose mechanism driven by an electromagnetic actuator used in an automotive internal combustion engine. The electromagnetic actuator is mounted in a housing mounted on an internal combustion engine body. A first stem has its tip abutting the valve, which is provided with a retainer and carries a first coil spring. A second stem is provided on the other side of an armature. The second stem has a retainer. Between this retainer and the housing, a second coil spring is mounted. At least one of these parts is made of a metal smaller in specific weight than iron or its alloy. Each retainer has a boss and an arcuate corner portion having a radius of curvature R of 1.0 mm or over between a spring abutting surface and the boss to relieve stress concentration.

摘要： This method minimizes the change in the range of pressure increase and reduction with change in the viscosity of brake fluid due to change in the temperature of brake fluid and a delay in pressure increase and reduction due to change in the brake fluid viscosity. A pressure sensor having a zero-point temperature drift function and a pressure sensor having no such drift function are provided to estimate the brake fluid temperature based on the difference in output between the two pressure sensors. Fluid pressure is controlled according to a control mode corresponding to the fluid viscosity based on the estimated fluid temperature. Specifically, the time during which electromagnetic valves are open is changed, or in the arrangement in which an electromagnetic proportional pressure control valve is used, the current supplied to its electromagnet is changed based on the estimated brake fluid temperature.
