摘要： To provide a surface profile measurement apparatus capable of efficient measurement of the surface profile of an object. A diamond indenter (16) is movably mounted. The tip end of the diamond indenter (16) is irradiated by light, and the light reflected by the tip end (17) is condensed through a lens (46). The condensed light is observed by a photo sensor (42) for measurement of the curvature radius of the tip end (17). Meanwhile, the light reflected by the tip end (17) and the light reflected by a reference body (66) together cause an interference fringe. The interference fringe is observed by a CCD camera (44) to measure the surface profile of tip end (17).

摘要： In a brake (53) for a hydraulic motor (10), a braking piston (66) is added that can move toward and away from fixed friction discs (54) and rotating friction discs (55). A braking passage (73) leads a high-pressure fluid into the braking piston (66) to press the braking piston (66) to the friction discs (54, 55).

摘要： An interferometer and method for performing preliminary and main measurements quickly and with high precision are provided. Laser light and white light are successively introduced to the same interferometer booth. Laser light is introduced from a laser light source, and the interference fringe with a reference mirror as a reference is detected using a CCD and a personal computer. By setting the interference fringe to a preset value, the position of a work is adjusted. White light from a halogen lamp is then introduced, a corner cube moving mount is moved, interference fringe with a reference mirror as a reference is detected, and preliminary measurement of the work is performed. Next, laser light is introduced, interference fringe with a reference mirror as a reference is detected, and the main measurement of the work is performed. Because the preliminary and main measurements are performed within the same interferometer booth, the number of steps is reduced and high precision preliminary measurement can be performed.

摘要： A first friction clutch (54) is constructed as a negative type friction clutch and a second friction clutch (55) is constructed as a positive type friction clutch. Spring constant of a second spring (75) is made smaller than that of a first spring (65). Therefore, in the middle stage of switching the first and second friction clutches (54, 55), both of these first and second friction clutches (54, 55) enter in a connection state. Consequently, a driven member (56) is driven through either or both of the first and second clutches by a driving shaft, and the free rotation state does not occur.
