Abstract: This invention relates to a cylinder with a built-in stroke sensor which is mounted to machine and equipment used in a rigorous environment, such as construction equipment. The cylinder of this invention minimizes a storage space for the stroke sensor and facilitates inspection/replacement of the stroke sensor. To this end, an eccentric member 8 is fitted to the tip of a sensor rod (6) and this member is equipped at its center with recessed portion (10, 11) which is coaxial with the sensor rod (6) and at its tip with projecting or recessed portion (9a, 9b) supported pivotally by recessed or projecting portion (3a, 3b) disposed at the center of the end surface of the rod head (3). A ring-like member (4) that engages with the recessed portion (10, 11) of the eccentric member 8 is fitted into the hollow portion of the piston rod (2). The projecting or recessed portion (9a, 9b) that is supported pivotally by recessed or projecting portion (12a, 12b) disposed at the center of the end surface of a bottom (12) may be provided to the tip of the eccentric member (8) and the ring-like member (4) engaging with the recessed portion (10, 11) of the eccentric member 8 may be fitted to the hollow portion of the cylinder (1).

Abstract: A device for mounting a position detecting sensor for detecting a stroke of a cylinder. It has such an arrangement that a rotary angle of a magnetic sensor (1) is regulated to within +/-5 degrees by a slit (9) formed in a housing (2) mounted thereon with the magnetic sensor (1) and a rotation-locker (7) mounted on a cover (6), the slit (9) allows the housing (2) and the cover (6) to slide on each other, but does not allow the both members to fall off each other, and the cover (6) and a head (4) are aligned with each other by a knock pin (10). With this arrangement, assembling work and highly accurate positioning can be easily performed. Furthermore, according to the present invention, a slit (21) is provided in the top portion of the sensor (1), the position of which can be adjusted by a collar (16) driven thereinto with a pin (17), after the adjusting, the sensor (1) is mechanically pressed by a cover (22) to be fixed or fixed by a mold material, so that an output of the sensor (1) can be controlled to be in an optimal state. Further, a block (20) mounted thereon with the sensor (1) is adjustably installed on a cylinder head (23), the sensor can be set to the position of a magnetic scale with ease, and the sensor (1) and the block (20) can be easily replaced with new ones.

Abstract: A method of processing the surface of a metallic rod, wherein films (2, 22 and 32) are applied onto portions other than the shape where grooves are to be formed on the surface of the rod, the surfaces of the rods (1, 21 and 31) which are not coated are dissolved and processed by chemical polishing or etching, whereby patterns of very shallow grooves (6, 24 and 34) are formed on the surface of the rod, so that making of grooves on the surface of a very heavy rod, a long rod and a curved rod, which have been considered difficult by the conventional machining, can be easily and highly accurately carried out. Furthermore, after the making of the grooves, the surface of a rod (41) excluding the groove portions and recessed portions (43) is plated in a state (42) of being coated by resist films and screens, whereby the grooves and the recessed portions (43) are plated (44), and thereafter, the coating films (42) are removed by buffing (45) and the like and the plated surface is finished, thus effectively plating the grooves and the recessed portions.
