    • PROBLEM TO BE SOLVED: To provide a rotation detector with high detection accuracy, which is easily fixed to a detection object having a circumferential side without the need for complicated processes to the joint of an encoder pattern.
      SOLUTION: This rotation detector is equipped with: a pattern support member 12 which has an annular pattern holding part 11 for holding the encoder pattern 11a and is supported by a drive shaft 1 whose rotation is to be detected; and a detection means 20 which detects the pattern change at a specific rotation detection position on a pattern rotation circumference when the pattern support member 12 is rotated. The pattern support member 12 is constituted by a plurality of division objects 31, 32 having circular sections, respectively, and the division objects 31, 32 are connected to each other. The detection means 20 has a plurality of detection parts 21, 22 which detect the change of the pattern 11a at the plurality of rotation detection positions P1, P2 having different spacing angle θs from the center angles of the circular sections of the division objects 31, 32 on the circumference where the pattern 11a is rotated.

    • PROBLEM TO BE SOLVED: To provide a spool valve enabling appropriate control of fluid pressure, and sufficiently securing quantity of fluid flowing in the valve.
      SOLUTION: A spool valve is disposed in a hydraulic control circuit and includes a valve body 31 and a spool 20 fitted in the valve body 31 in such a manner that the same strokes in an axial direction (axial direction of a center axis 101). The spool 20 includes a shaft part 21 extending in the axial direction, land parts 22m, 22n, and flange parts 23. The land parts 22m, 22n are formed on the shaft part 21, and define an oil flow space 32. The flange parts 23 are formed with expanding in a radial direction from the shaft part 21, and are disposed between the land parts 22m, 22n. The flange parts 23 are formed with mutually shifting in the axial direction, and include half divided sections 24, 25 mutually divided in a circumferential direction having a center at the shaft part 21.

    • PURPOSE:To ensure riding comfort over a bad road in regard to the suspension control device which enables maneuvering stability to be compatible with riding comfort by controlling the spring characteristics, damping force characteristics and the like of a suspension mechanism. CONSTITUTION:A vehicle speed (v) and a steering angular velocity d/dt are computed (step 100, 102). The degree of a bad road is computed based on the vertical acceleration of a vehicle (step 104). A map corresponding to the computed degree of a bad road is searched by (v) and d/dt, so that damping force is thereby determined (step 108-1 through 108-n). Each hold time holding damping force hard in response to respective various conditions is determined (step 110-1 through 110-1). The map allows damping force to be as hardly held hard as a road is bad, and also allows each hold time to be set as short as a road is bad. Damping force and each hold time are realized, so that processing comes to an end.
