Title: Focus detector
Inventor: ISHIDA TOKUJI
IPC: G02B7/34
Filed: 1990-07-03
Abstract: PURPOSE:To accurately discriminate the possibility of accurate focus detection or the reliability of its detection result by standardizing the best correlation value that a 1st image signal and a 2nd image signal have the best correlation with the contrast of a subject image, and discriminating whether or not the focus detection is possible according to the standardized value. CONSTITUTION:Even if the best correlation value obtained for a high-brightness, high-contrast subject and the best correlation value obtained for a low- brightness, low-contrast subject are equal, the subjects are different in contrast, so the standardized correlation value varies correspondingly. Here, the best correlation value that the 1st image signal and 2nd image signal have the best correlation is standardized with the contrast value of the subject image and whether or not the focus detection is possible is discriminated according to the standardized correlation value. Consequently, whether or not the focus detection is possible or whether the focus detection result is reliable can be accurately be discriminated.

Title: Fiber optical photoamplifier
Inventor: UEIN BUIKUTAA SOURIN
IPC: H01S3/23
Filed: 1984-08-25
Abstract: A fiber optic amplifier is disclosed, comprising a fiber optic, monomode waveguide (20) having a core (64) and cladding (66). A portion (70) of the cladding (66) over a predetermined region is removed and replaced by an active medium (30) capable of absorbing light energy at a first wavelength and emitting light energy at a second wavelength. The active medium (30) is a lasing dye that has an index of refraction adjusted to be slightly less than the index of refraction of the fiber core (64). The amount of cladding (66) removed is adjusted such that a predetermined amount of penetration of the evanescent field from a pump light signal (36) coupled into an end of the fiber (20) penetrates the active medium (30). A probe signal (38) to be amplified causes stimulated emission from the excited dye molecules by penetration of its evanescent field into the dye (30) in the region where the cladding is removed.In the preferred embodiment a recirculating pump (110) is used to circulate dye (30) through a cavity (112) placed over the fiber (20) where the cladding portion (70) is removed. The dye molecules in contact with the surface (72) formed by removal of the cladding (66) are continually changed. A temperature control unit (110) maintains the temperature of the dye (30) such that its index of refraction remains tuned to an amount just less than the index of refraction of the core (64).

SOLUTION: By etching copper foils on a substrate 20, conductive patterns are formed to form simultaneously with these formations two circular first marks 30 in the two asymmetric corner places of the substrate 20 by etching the copper foils. Then, insulation films are applied to the places requiring insulations to form simultaneously with these applications two rectangular second marks 40 outside the two first marks 30 by the insulation film. Further, on the insulation films, printed patterns made of a carbon paste are formed to form simultaneously with these formations two triangular third marks 50 inside the two first marks 30 by the carbon paste.  Thereby, the positional discrepancies among the formed conductive patterns, insulation films and printed patterns on the board 10 can be sensed merely by the visual inspections of the positional discrepancies among the marks 30, 40, 50 formed in the forgoing two places.

Abstract: PURPOSE:To improve the oxidation resistance of a transition-metal electrode- wiring material by applying a metal or a semiconductor, thickness thereof is that of a monomolecular layer or more and oxide forming energy thereof takes negative value larger than that of a transition metal as a foundation, onto the transition metal.

In this case, the metal or semiconductor film 2 consists of a material easy to form an oxide more than the transition metal 1 as a foundation (the forming energy of the oxide takes negative larger value), and its thickness extends over that of a monomolecular layer or more. Consequently, the transition metal is reduced by said material even when the transition metal is oxidized. Said material is oxidized, and the material as the foundation can be protected by the oxide film and a section not oxidized.
