Abstract: An oblique projection optical system is provided with a first group lens system, a second group lens system and a third group lens system that are placed in succession from a short conjugate length focal surface, and each lens system has a plurality of single lenses. The first group lens system contains a beam regulator to form a telecentric structure. The second group lens system is set to have a great tilt decentration and a parallel decentration with respect to the first group lens system. The third group lens system is set to have a great tilt decentration and a parallel decentration with respect to the second group lens system. In this manner, instead of making the lenses decentered inside each lens system, the respective lens systems are made decentered from each other; thus, the resulting projection device is easily manufactured, and makes it possible to correct the distortion aberration and focal position on the screen surface, and to project an image with high precision.

Abstract: When a scanning start position set signal is input in an area image sensor, the content is transferred to a vertical scanning circuit, and the scan start position is set. Image of a desired row is read by horizontal scanning. Then, one shift signal for vertical scanning is input, the position of scanning is shifted by one row, and horizontal scanning is performed. Thus image of the next row is read. By repeating this operation, a desired strip-shaped image is read. The shape of the object is determined and when a portion is determined to have complicated shape, the image data is input by means of a lens having long focal length, and image data of other portions are input by means of a lens having short focal length. By putting together a plurality of input image data, image data as a whole is generated.

Abstract: A three-dimensional measurement device employs a slit ray projection technique to optically determine a three-dimensional image. The device offers a choice in operating modes between high-speed measurement, high-resolution measurement and large dynamic range in the depth direction, to accommodate various situations. The different modes of operation are achieved by selectively modifying one or more of the scanning speed of a projected reference beam, the readout speed of a photosensor, the line width or line spacing of the photosensor, and the number of lines per image frame.

Abstract: In a magnetic disk drive, a head carriage assembly includes a slider which is directly adhered to a carriage. The assembly, therefore, needs a minimum of constituent parts and a minimum of assembling steps. The absence of a conventional metal plate reduces the thickness of the assembly and, therefore, the overall thickness of the disk drive. The weight of the assembly is reduced in the front part of the carriage. This successfully reduces a period of time necessary for an overshoot and vibration occurring during seek due to a drive motor to attenuate, thereby reducing the reading time and writing time.

As a result, the video signals output from the TV camera are averaged to prevent an offensive image to the eye of the display.
