| Number | Title | Issue Date |
| 7199810 | Beam scanning apparatus having polarization direction adjuster A beam scanning apparatus projects a beam onto a photoconductive drum according to corresponding image data, and includes a micro polarized array which is formed to receive a beam emitted from a light source and has a plurality of polarized cells arrayed in a predet... | 04/03/2007 |
| 6897946 | Ranger finder device and camera A range finder device, for measuring, when a plurality of projected lights having radiation patterns whose light intensity differs three-dimensional space-wise are irradiated onto an object from a light source on a time-sharing basis to image-pick up reflected light... | 05/24/2005 |
| 6072566 | Optical rotary device and manufacturing method thereof and image display device using thereof A photoresist is applied to a first substrate made of glass or resin which has been subjected to alignment treatment. Next, the photoresist is exposed and developed by UV light so as to form a non-optical rotatory region in a stripe manner after a mask ha... | 06/06/2000 |
| 4856894 | Distance measuring method and means In the method, relatively inclined beams of light are projected towards the target from spaced locations at the station from which the distance to the target is to be measured. The locations are moved relative to one another along a linear path to bring t... | 08/15/1989 |
| 4697921 | Device for detecting a relative change in distance between two measuring points, and its use As is known, the walls in cavity structures often become quiescent only after a prolonged period. In order to detect whether and to what extent rock displacements can occur, measuring instruments are installed at mutually opposite points (I, II) on walls ... | 10/06/1987 |
