Filed: 1996-11-06
Abstract: PROBLEM TO BE SOLVED: To provide a fluorescent paint metal plate scarcely damaged, having excellent chemical resistance and stain resistance and continuing fluorescence for a long period. SOLUTION: An outer layer of fluorescent paint composition is formed on the metal material. The composition is obtained by blending fluorescence containing metal oxide as a main component with inorganic paint containing silicone compound as a main component. Since the fluorescence is inorganic compound, it is scarcely deteriorated by a light, and fluorescence can be continued for a long period. Since the paint itself is inorganic paint, an obtained painted film has high surface hardnes, and hence it is scarcely damaged. Since its chemical resistance and stain resistance are excellent, it is scarcely deteriorated, contaminant substance is scarcely adhered. Further, from this, a light for exciting the fluorescence is emitted to the fluorescence in the film without shutting off it, and this can hold the fluorescence for a long period.

Abstract: PURPOSE:To obtain a reliable resin-sealed semiconductor element which is able to contrive high density packaging and its easy handling by forming bump electrodes to provide them at least on one main surface of a resin layer which seals the mainframe of the semiconductor element. CONSTITUTION:A resin-sealed semiconductor element 1 which constructs the mainframe 2 of its element by sealing it with resin is formed in such a way as to allow bump electrodes to protrude toward the surface of a covering and sealing layer 3b with resin and both covering and sealing layers with resin 3b and 3a cover and seal respectively surroundings of the mainframe 2 of the element at the prescribed thickness. In this way, the surroundings of the mainframe 2 of its element are thinly covered and sealed with resin. Since the bump electrodes 6 are exposed out of the covering and sealing layers 3a and 3b with resin and these electrodes act as external connecting terminals, its configuration makes this element compact. As the resin layers 3a and 3b, therefore, cover and seal the mainframe 2 of the element, moisture resistance is improved. This approach enables the element to contrive high density packaging and its easy handling.

Filed: 1989-11-15
Abstract: PURPOSE: To increase the circuit operation speed and to improve the reliability by giving a highly parallel pipeline architecture to a display processor for the internal structure of a solid object to quickly generate a visible image. CONSTITUTION: A comparator 151 determines whether a new value of Zd is smaller than the preceding stored value of Z of the same xd and yd coordinates or not; and if it is smaller, an AND gate 153 is energized by the output signal of the comparator 151 to store the new depth value in a depth buffer 152. Simultaneously, an AND gate 155 is energized to rewrite old strength data in a frame buffer 154. Thus, contents of the buffer 154 consist of only display points closest to the observation plane after all display points of a display list 140 are completed used. Thus, a visible image is quickly generated because the display processor for the internal structure of the solid object has a highly parallel pipeline architecture, and therefore, the circuit operation speed is increased and the reliability is improved.

Title: Collimator and collimator array
Inventor: NOGUCHI KAZUHIRO
IPC: G02B27/30
Filed: 1994-11-29
Abstract: PURPOSE: To relax relative position precision conditions between an optical fiber and a convex lens and to facilitate the manufacture and reduce the insertion loss by using a core-expanded optical fiber which is larger in core diameter on an end surface than inside the fiber. CONSTITUTION: The core-expanded optical fiber 12 is used which is larger in core diameter on the end surface than inside it. A housing 13 holds a convex lens 11 and the core expanded optical fiber 12 so that the converged beam waist position (focus position) of the convex lens 11 meets the projection light beam waist position of the core-expanded optical fiber 12 and the optical axes of the both are aligned with each other. In general, the core-expanded optical fiber 12 is expanded in the beam spot radius of a projection light beam waist as compared with an ordinary single-mode optical fiber. Therefore, the coupling loss never increases even when the beam spot radius of a converged light beam waist transmitted through the convex lens 11 is increased.  Consequently, the beam spot radius of the converged beam waist can be increased and the relative position precision conditions of the convex lens 11 can be relaxed.
