摘要： Light emitted from a light emitting device is reflected by a first reflection curved face so that the travel direction of the light is almost perpendicularly diffused, the light is reflected by a reflection face circumferentially formed on an end face of a rotor in the direction parallel to an axial line, and after that, the light is supplied to a stator side along a cylindrical part on the outer periphery of the rotor. In a stator, light is condensed again in the axial direction by a reflection face and, after that, the light is reflected by a second reflection curved face and is received by a photo sensing device. In this instance, since the light passed through whole slits on the end face of the rotor and whole slits in the peripheral part of the stator is converged and then detected by an FG, the signal level upon detection is increased, the detection accuracy is improved at low cost.

摘要： Disclosed is an imaging apparatus capable of enlarging a portion of an image captured by an imaging device of a fisheye camera and displaying the enlarged image on a display screen with little distortion. The imaging apparatus enlarges a section, which is a portion of an image captured by a fisheye camera, and displays the section on a display screen such that the enlargement ratios of points in the section are different from each other. An image processing method uses a change function that changes the enlargement ratio of a field angle depending on the place is used, and converts a portion of the captured image into a central projection image to generate a display image. The use of the change function makes it possible to generate a display image having high visibility.

摘要： A flow path is formed in a zigzag shape to have a predetermined width from an upstream side to a downstream side. Accordingly, both side surfaces of the flow path divide the flow path into a plurality of regions from the upstream side to the downstream side to function as regulation surfaces for regulating the number of test particles filled inside the regions. Further, when a test is performed on each of the regions, the accumulated amount of tolerances of the test particles in the respective regions is small, which makes it possible to test the test particles with high accuracy.

摘要： When a voltage is applied between outside electrodes and a common electrode that constitute driving parts of a driving unit provided between a holder holding a lens and a lens barrel, as shown in FIG. 9, respective dielectric elastomers provided in the driving parts are slightly deformed in a direction that is crushed in an X1-X2 direction. Thus, the entire lens can be slightly moved in the direction of an arrow (X2-direction). This enables an optical axis O′-O′ of the lens to coincide with or get closer to a reference optical axis.
