Abstract: In an optical movement information detector, light emitted from a laser diode (1) is split into a first beam (10), a second beam (11) and a third beam (12) by beam splitters (2a, 2b). The first, second and third beams are converged by a condenser lens (4) upon a surface of an object to be measured (5) to form a beam spot (13) thereon. Diffused light from the beam spot (13) is received by a photodiode (6) and an output signal of the photodiode (6) is processed by a signal processing circuit (20) including an analog-digital converter (8) and a Fourier transforming unit (9). A detecting section (21) obtains, for example, a moving velocity and a moving direction of the object based on spectrum peak frequencies obtained by the Fourier transform.

Abstract: An object of the present invention is to increase efficiency in review work by appropriately narrowing down review work that verifies shapes of visual defects relating to an enormous amount of defects detected by a visual inspecting apparatus with high sensitivity. In order to appropriately extract defect information from an inspecting apparatus, a filter function and a sampling function are prepared by unitizing the functions. As a result, defects as review targets are narrowed down and extracted automatically using the filter function and the sampling function in combination. In addition, sequencing the filter conditions and the sampling conditions and registering the sequence enables automatic filtering and sampling on the basis of information on a wafer as a review target, and thereby only defect information on the review target is extracted.

Abstract: There is provided an optical velocimeter for achieving miniaturization and lower power consumption thereof and for accurately detecting two-dimensional travel velocity of a measured object. This optical velocimeter includes a light-emitting element, a diffraction grating, two light-receiving sections, and a signal processing circuit. Light emitted from the light-emitting element is branched by the diffraction grating into three light fluxes, and optical axes of the divided light fluxes are intersected one another on the measured object to form one detection point. Scattered light from the detection point frequency-shifted by travel of the measured object is then received by the two light-receiving sections, and a light-reception signals outputted from the light-receiving sections are processed in the signal processing circuit to detect travel velocities of two directions of the measured object.

Abstract: A hydraulic actuator comprising a pair of pressure oil chambers each of which has a cushioning port, the two cushioning ports being connected to each other through a cushioning means. The cushioning means includes a pair of cracking valves whose closing pressure is lower than its opening pressure and a pair of restricting means for restricting the flow of a pressure oil provided with regard to said cracking valves. This structure permits an output means for the actuator to be stopped smoothly as a result of fully absorbing the inertial energy that accompanies the output means.
