Abstract: A sensor appropriately detects the state of a fluid while reducing the effects of fluid temperature on fluid characteristics. The sensor includes a characteristics acquisition unit, a temperature measurement unit, a storage unit, and a correction unit. The characteristics acquisition unit acquires a characteristic value for an in-device fluid. The temperature measurement unit measures the in-device fluid temperature when the characteristics acquisition unit acquires the characteristic value. The storage unit stores a database registering an association between a pre-acquired characteristic of the in-device fluid and the in-device fluid temperature measured when the characteristic of the in-device fluid was pre-acquired. The correction unit corrects the characteristic value of the in-device fluid acquired by the characteristics acquisition unit based on the in-device fluid temperature measured by the temperature measurement unit and the database.

Abstract: A damper control device includes a rate sensor that detects a pitching angular velocity of a vehicle body, a vehicle speed sensor, a steering angle sensor and a calculation unit that detect a roll angle and a yaw angular velocity of the vehicle body, a pressure sensor that detects a pressure of a contraction-side chamber in a front-wheel side damper, a pressure sensor that detects a pressure of a contraction-side chamber in a rear-wheel side damper, and a correction unit that corrects the pitching angular velocity. The pressures are controlled on the basis of the corrected pitching angular velocity and the pressures. The vehicle speed sensor, the steering angle sensor and the calculation unit detect the roll angle and the yaw angular velocity on the basis of a traveling speed and a steering angle.

Abstract: A fluid pressure control device includes a switching valve configured to switch an operation of an operate check valve, a relief valve configured to open when a pressure in a load-side pressure chamber reaches a predetermined pressure, and a relief discharge passage configured to lead a relief fluid discharged from the relief valve to a tank. The switching valve includes a piston giving thrust to a spool upon receipt of a pilot pressure on a back surface, a drain chamber defined by the spool and the piston, and a drain passage allowing the drain chamber and a spring chamber to communicate with the relief discharge passage. The relief fluid discharged from the relief valve is discharged to the tank through the relief discharge passage and does not operate the switching valve.

Abstract: Providing a seal member taking-out device which can successfully take out a larger number of seal members. The seal member taking-out device includes a shaft member, a cylinder member, a moving member, and a taking-out member. The shaft member is columnar or cylindrical. The cylinder member is cylindrical and the shaft member is inserted through the cylinder member so that the cylinder member is movable in a direction of a central axis of the shaft member. The cylinder member is shorter than the shaft member and extends in the direction of the central axis of the shaft member. The moving member moves a plurality of seal members stacked on the shaft member and the cylinder member, in a direction of a distal end of the shaft member. The taking-out member takes out the seal members from the distal end of the shaft member.

Abstract: A vane pump includes a high-pressure chamber formed as a groove in a bottom portion of a pump-accommodating concave portion. The working fluid is discharged from a plurality of discharge ports leading to the high-pressure chamber. A high-pressure passage has an opening portion opening to the high-pressure chamber and guides the working fluid to the outside of the high-pressure chamber. In the vane pump, one of the plurality of discharge ports is arranged so as to face the opening portion of the high-pressure passage, and the flow-passage cross-sectional area of the high-pressure chamber is smaller than the total flow-passage cross-sectional area of the plurality of the discharge ports.
