摘要： A direct drive type servo motor in which a spool is driven directly by a force motor, the force of the force motor being balanced by the reactional force generated by a resilient member to stabilize the position of the spool to control the flow of working fluid. The resilient member is constituted by a metallic cylindrical member having holes formed in the outer peripheral surface thereof. The holes are arranged such that, when the force is applied to the cylindrical member in the axial direction, the cylindrical member produces an axial reactional force. In consequence, the generation of force component which would act to press the spool against the sleeve is avoided to reduce the friction between the spool and the sleeve to permit a smooth movement of the spool, while allowing the resilient member to have a high spring constant to improve the response characteristic of the servo valve.
摘要翻译：一种直接驱动型伺服电动机，其中线轴由力马达直接驱动，力马达的力由弹性构件产生的反作用力平衡，以稳定卷轴的位置以控制工作流体的流动。弹性构件由在其外周面形成有孔的金属圆筒构件构成。这些孔被布置成使得当沿轴向方向将力施加到圆柱形构件时，圆柱形构件产生轴向反作用力。因此，避免了将作用以将线轴压靠套筒的力分量的产生，以减小线轴和套筒之间的摩擦，以允许线轴的平稳移动，同时允许弹性构件具有高的弹簧常数提高伺服阀的响应特性。

摘要： A hydraulic operating apparatus including an actuating cylinder having a piston arranged therein and moved by a fluid under high pressure further includes a control valve having only one metallic seal whether the piston is at its upper or lower positions. The control valve is operative to apply the fluid under high pressure to a pressure receiving surface of the piston on the opposite side of a piston rod to move the piston in a direction in which the piston rod extends from the piston and to discharge the fluid existent on the opposite side of the piston rod from the actuating cylinder to move the piston in a direction opposite the direction in which the piston rod extends from the piston. The hydraulic operating apparatus further includes a seal for dividing the pressure receiving surface of the piston on the opposite side of the piston rod into first and second pressure receiving surface sections, the first pressure receiving surface section having an effective pressure receiving area smaller than that of a pressure receiving surface of the piston on the side of the piston rod.

The driving means for level correction comprises an accumulator and an electromagnetic valve and the electromagnetic valve is actuated by the electric signal from the position detecting means, so that the hydraulic fluid in a cylinder forming a part of the driving mechanism of the elevator is withdrawn into a tank, or the hydraulic fluid in the accumulator is conducted into the cylinder to thereby correct the level of the cage.

摘要： A fluid pressure drive device including a primary drive portion operated by receiving an operational command, and a secondary drive portion operated due to the operation of the primary drive portion. In this fluid pressure drive device, at least parts of movable members in the above both drive portions are overlapped so as to shorten the lengths of fluid passages. As a result, a time interval from the receiving of an operational command until the generation of a drive force in the final drive portion, i.e., a response time of the drive device may be shortened.

摘要： A gage control system for a rolling mill for compensating for variation in the thickness of rolled material due to variations in the rolling load or pressure. In the system, the roll eccentricity frequency produced by the eccentricity of the rolls is detected and utilized for softening the effective rigidity or stiffness of the mill, that is, weakening the apparent mill modulus by control means according to the frequency of roll eccentricity. To this end, a positive feed back path including an eccentricity control unit is provided in parallel with a feed back path of the rolling pressure signal of a gage control circuitry of the so-called BISRA system. The eccentricity control unit serves to detect the roll eccentricity on the basis of a correlation principle and compensate for or cancel the effects of the feed back of the rolling pressure upon the occurrence of the roll eccentricity.
