Abstract: An optical apparatus of the invention has a fusion splice portion where respective ends of two optical fibers each having a core, a cladding, and a UV coat portion provided on the outside of the cladding are fusion spliced, and a re-coat portion which re-coats a portion where the UV coat portion is removed in the vicinity of the fusion splice portion is formed using a material capable of absorbing light radiated from the fusion splice portion. As a result light which is radiated from the fusion splice portion can be reliably prevented from coupling into another optical fiber adjacent to an outside of the re-coat portion.

Abstract: A method of manufacturing plasma display panels using a substrate holder for deposition on a substrate of the plasma display panel. The substrate holder is configured with plural frames, and the substrate of the plasma display panel is held by its periphery with at least one of these frames. A frame holding the substrate has a protrusion extending to a non-deposition face of the substrate held in such a way as to surround the substrate. Since the protrusion acts as a blocking sheet, attachment of a deposition material passing through an opening on the substrate holder and reaching onto the non-deposition face of the substrate is suppressed.

Abstract: A color correction circuit is best adjusted to consistently obtain a stable, color printing by compensating for a change in the characteristic of a printer under the influence of ambient temperature and humidity.Before the printing of pictorial data, e.g., an image, (reference data produced by a reference data generator), is entered into a printer engine by which it is printed out on a sheet of a paper. This printed data is read in by a color sensor, which in turn produces an output detection signal. A feedback control circuit produces a control signal necessary for a color correction according to the output signal of the color sensor and then sends it to the color correction circuit. The color correction circuit is adjusted and corrects the colors of the pictorial data to be printed. The corrected data is printed out. Repeating this process for each color printing can prevent a variation in the printed colors due to the effect of ambient temperature.

Abstract: In an image display device having a frame rate converting (FRC) portion, it is possible to prevent image degradation of a combined image display portion such as an OSD and PinP attributed to the FRC process. The image display device includes: an FRC portion 10 for converting the number of frames of an input image signal by interpolating an image signal subjected to a motion compensation process between the frames of the input image signal; an OSD processing portion 14 for superposing an OSD signal on the input image signal, and a controlling portion 15. The FRC portion 10 has a motion vector detecting portion 11e for detecting a motion vector between the frames of the input image signal, an interpolation vector evaluating portion 11f for allocating interpolation vector between frames based on the motion vector information, and an interpolation frame generating portion 12d for generating an interpolation frame from the interpolation vector. When the OSD signal is superposed on the input image signal, the controlling portion 15 disables the motion compensation process of the FRC portion 10 by making the motion vector detected by the motion vector detecting portion 11e 0 vector.

Abstract: Upper and lower wire guides in a wire-cut electric discharge machine are moved until a wire electrode contacts with a workpiece, and after the contact, the upper and lower wire guides are moved backward to a position A which is away from the contact point at a fixed distance. Then, the upper wire guide is moved until the wire electrode contacts with the workpiece and the upper wire guide is returned to the position A. Subsequently, the lower wire guide is moved until the wire electrode contacts with the workpiece and the lower wide guide is returned to the position A. A coordinate value on the position where the wire electrode contacts with the workpiece is calculated by using position detection values which are obtained in the above respective steps, and board thickness is calculated from the coordinate value.
