Title: Position detector
Inventor: TENMIYOU SHIGEMOTO
IPC: G01D5/36
Filed: 1983-04-01
Abstract: PURPOSE:To elevate the detection accuracy checking adverse effect from dust or the like with a simple construction by arranging an optical system for converging lights from a plurality of light sources, light transmitting/shielding means and a light receiving means. CONSTITUTION:Lights from light sources 7a and 7b form a converged light and converges at convergence points at the center of a slit plate 8. A light transmitting section F and a light shielding section G are formed alternately on the slit plate 8 and as the spots of the converged light on the transparent plate 9 are larger enough that a slit pitch P, possible effect can be reduced remarkably even when dust or the like exists on the transparent plate 9 than when dust attaches directly on the slit plate 8. On the other hand, as the slit plate 8 moves in the direction M, pulses are counted from variations in the quantity of light cylically incident into photo detectors 10a and 10b thereby enabling detection of the position of the slit plate 8. Thus, the lowering of the detection accuracy due to dust or the like can be prevented with a simple construction thereby maintaining a stable performance for a long time.

Title: Dozing condition detection device
Inventor: KANEDA MASAYUKI
IPC: A61B5/18
Filed: 1997-02-24
Abstract: PROBLEM TO BE SOLVED: To detect a dozing condition stably by detecting the position of eyes accurately. SOLUTION: In the input image of a face shot by a TV camera, its first point is extracted from the concentration peak of picture element lines in the vertical direction of the face, and a group of curved lines which extend in the horizontal direction of the face are extracted by joining the first points of the picture element lines adjacent to each other. By using characteristics in a general positional relation between eyes and other parts such as eyebrows in the face, of this group of curved lines, the curved lines representing the eyes are identified to detect the position of the eyes.  By setting a prescribed area including the position of the eyes, extracting the second point indicating the position of the eyes from it, which is the same as the first point, and detecting the opening of the eyes fore and aft (vertically) based on boundary point intervals of concentration peak, a vigilance degree is discriminated from a change in its opening/closing condition. The extraction of the first and second points is conducted by assigning a concentration peak A where the differential value of the concentration reverses from negative to positive, discriminating whether or not a condition that the minimum and maximum differential values B, C of its front and rear exceed prescribed values is satisfied.

Title: Manufacture of polycrystal silicon thin film and device therefor
Inventor: SUMIYOSHI KEN
IPC: H01L21/203
Filed: 1986-03-13
Abstract: PURPOSE:To obtain a polycrystal silicon thin film with large diameters of crystal particles, by irradiation of electron beams to form the polycrystal silicon thin film. CONSTITUTION:Electron beams accelerated are radiated on a surface of an insulator substrate 101 installed inside a vacuum container 100, and acceleration voltage of the electron beams is selected to heat only the surface of the insulator substrate 101. And the surface of the insulator substrate 101 is exposed in silicon vapor or silicon compound gas which is produced by heating solid silicon 107. Silicon atoms or silicon compound molecules, which attain to the surface of the insulator substrate 101, can move on the surface, with a large distance on account of electronic energy gained by irradiation of the electrons then accelerated, to form crystal cores in the atoms or molecules within a range of this distance. Hence, a crystal core generated factor per unit area becomes lowered to obtain a polycrystal silicon thin film with large diameters of crystal particles.
