摘要： PROBLEM TO BE SOLVED: To efficiently and evenly eliminate static electricity of charged resin hollow containers, and to improve the conveying efficiency of the hollow containers. SOLUTION: This method for static elimination of at least one resin hollow container 3 comprises a conveying process of conveying the hollow containers 3 along a guide part 4, and an X-ray irradiation process for irradiating the hollow containers 3 with X-rays when the containers 3 are located in the prescribed position. When each hollow container 3 is conveyed along the guide part 4 and located in the prescribed position to be irradiated with X-rays, the X-rays penetrate the hollow container 3. Here, the gas near an internal surface 3c and an external surface 3c of the hollow container 3 is ionized to generate ions independently of the shapes of the charged hollow container 3, so that electricity is eliminated in batch and evenly from the internal surface 3c and the external surface 3b.

摘要： PROBLEM TO BE SOLVED: To prevent degradation of sensitivity and production of moir* by installing a correspondent micro-lens on each of the photoelectric conversion sections of a solid-state image pickup device, which are arranged on the major surface of a semiconductor substrate in two-dimensional lattices, and installing an optical fiber handle having optical fibers arranged in two-dimensional lattices attached thereon. SOLUTION: Light incident on an optical fiber handle 42 is propagated through a core 43, and enters micro-lenses 11 through a filler 41. It is then focused on photoelectric conversion sections 1, and is subjected to photoelectric conversion into a signal charge. The virtual aperture rate of the photoelectric conversion sections 1 is increased by two or three times using the micro-lenses 11 to enhance sensitivity. Further, for nonuniformity of sensitivity due to difference in type and periodicity between the lattices of the photoelectric conversion sections 1 and the lattices of the core 43, the ratio of maximum sensitivity to minimum sensitivity is reduced, and thus moir* arising from such non- uniformity of sensitivity is significantly reduced. This enhances the virtual aperture rate, light utilization factor and sensitivity.

摘要： PURPOSE:To provide a new optical type light switch having the function equal to an electrostatic switch. CONSTITUTION:A phototransistor 20 is arranged on the output end surface of a fiber optical plate l to constitute a light switch. The fiber optical plate 1 is constituted so as to cover the outer circumferential part of a clad covering a cover with an absorbing body, and the inclination theta of an input end surface 2 is set to an angle such that the light incident to the core from the air never cause total reflection on the boundary surface with the clad. Thus, only the light incident from the part making contact with a finger 22 is propagated to the output end surface 3.

摘要： PROBLEM TO BE SOLVED: To provide a resin molded product producing method and apparatus capable of enhancing the transfer efficiency of a resin sheet and the yield of a resin molded product. SOLUTION: A resin molded product producing method includes a process for transferring a resin sheet 1 in a constant direction, a process for the molding processing of the transferred resin sheet 1, a process for cutting the molded resin sheet 1 to separate the same into a resin molded products 7 possible to laminate and a process for laminating the resin molded products. In this case, when the resin sheet 1 is transferred to be subjected to molding processing and the molded sheet is cut to be separated into the resin molded products 7 and these products 7 are irradiated with X-rays, X-rays transmit through the resin molded products 7 and air in the vicinity of the upper and rear surfaces of the resin molded products 7 is ionized to collectively and uniformly destaticize the resin molded products 7. Therefore, the mutual shift of the resin molded products 7 caused by electrostatic repulsion is prevented when the resin molded products 7 are laminated and it is prevented that the resin molded products are partially melted or scorched by the discharge between the resin molded products.

摘要： PURPOSE: To flatly form a touch surface and to form a device thin over the entire part by forming a curved part in part of a plate. CONSTITUTION: The slant FOP(fiber optical plate) 10a is constituted by bundling and integrating plural optical fibers. Its output end face 23 is cut perpendicular to the optical axes of the optical fibers and its input end face 2 is cut at an angle α with the optical axes of the optical fibers. The curved FOP 20a is constituted by curving a fiber plate bundled with the plural optical fibers to an arc shape and joining its input end face 2 to the output end face 33 of the slant FOP 10a. Further, the angle formed by the input end face 2 and the output end face 33 is regulated to the same angle αas the angle α of inclination of the input end face 2. The tapered FOP 30a is formed by bundling the plural optical fibers, forming the plate to such a tapered shape that its diameter changes continuously from the input end face 2 toward the output end face 33. The input end face 2 is joined to the output end face 33 of the curved FOP 20a.
