    摘要: A rotary movement converting mechanism for converting a rotary movement of a rotary body (43) into a linear movement of a movable body (2) has a support body (42) fixed to a body frame (3) and provided with a slit (42A) along an axial direction of the rotary body (43), a spiral groove (43A) formed on the inner circumference of the rotary body (43), and a top member (41) provided on the movable body (2). The top member (41) has an engaging member (41 A) inserted through the slit (42A) and having a tip end engaged with the spiral groove (43A), and a stop member (41C) for stopping the linear movement of the movable body (2) when a load is applied on the linear movement of the movable body (2). Accordingly, when a load is applied on the linear movement of the movable body (2), the linear movement is stopped and the minute displacement of the movable body (2) is restrained, thereby enhancing the stability of a measuring instrument in measuring a workpiece.

    摘要: A main scale graduation, an auxiliary scale graduation or the like provided in a conventional micrometer is omitted, and a thimble 71 is provided at a regular position in the axial direction of the spindle 61 through a sleeve 51 in a frame 1 to rotate about the axis of a spindle 61. Between the thimble 71 and the spindle 61, a rotation transfer means 81 for transferring the rotation of the thimble 71 to the spindle 61 and allowing the spindle 61 to displace in the axial direction of the spindle 61. As the rotation transfer means 81, a ratchet system 82 is used.

    摘要: A process for coating an aluminum article with zinc by immersing the article in an aqueous bath prepared by dissolving solid zinc fluoride in water. Preferably, the pH of the bath is about 4 to about 6. After coating, the article can be heated to diffuse zinc into surface-adjacent regions of the article and thereby to provide a zinc-diffused layer that protects the article against corrosion.
