Title: Optical fiber array
Inventor: WADA HIROSHI
IPC: G02B6/44
Filed: 1989-10-11
Abstract: PURPOSE:To eliminate the need for a grooved substrate and to inexpensively and efficiently produce the above optical fiber array by connecting and fixing the ends of plural pieces of optical fibers, from which protective coating layers are removed, by bringing the side faces into tight contact with each other or directly applying an unshaped adhesive material thereon. CONSTITUTION:Plural pieces of the glass optical fibers (bare fibers) 11 formed by removing the protective coating layers 20A of coated fibers 20 at the ends to expose the fibers are arranged in one array by bringing the side faces into tight contact with each other. These optical fibers 11... are connected and fixed at the points apart a slight distance from the end faces by the monolithic adhesive material 12 consisting of a metal plating film to constitute the optical fiber array 10. The joining strength is weak if the thickness of the metal plating film 12 is too thin. Production takes much time if the metal plating film is formed too thick and, therefore, the metal plating film is preferably formed in a 0.2 to 0.8mm, more preferably 0.3 to 0.5mm thickness. The need for the substrate having the fiber guide grooves precisely formed for each of the optical fiber array bodies is eliminated in this way and the mass production of the array at a low cost is possible. In addition, the drastic reduction of the size of the fiber fixing parts is possible.

Title: Tentative address system in radio communication system
Inventor: HOSHIKAWA NORIYA
IPC: H04W16/12
Filed: 1990-10-04
Abstract: PURPOSE:To attain the communication while many radio terminal equipments and base stations are separated and identified even with an address field of limited bit number by providing radio terminal equipment identification information as tentative identification information temporarily effective to only a base station area. CONSTITUTION:A tentative address number effective temporarily only to a base station is provided to address information of a radio terminal equipment and a number based on a repetitive zone number depending on a frequency repetitive pattern is provided to base station information as a tentative address number. Bit number representing a number equal to a channel number able to be set simultaneously at the base station only or over is enough for radio terminal equipment information of an address field, and since the base station information is a number based on the repetitive zone number, the very few bit number is required in any case. Thus, limitation of the number of radio terminal equipments and base stations to be accommodated depending on the transmission quantity (bit number) of the address field is eliminated.

Title: Pd module
Inventor: INABA KIMIO
IPC: G02B6/42
Filed: 1994-10-28
Abstract: PURPOSE: To provide a PD module which reduces return light with a simple structure by arranging an approximately wedge-shaped prism between an optical fiber and a light reception element. CONSTITUTION: An optical fiber 1 and a light reception element 2 face each other in a metallic package 4 and are held in this state, and an approximately wedge-shaped prism 7 is arranged in the light passing part between the end of the optical fiber 1 and the light reception element 2. A ferrule 3 for fixing to the metallic package 4 is attached to the end of the optical fiber 1, and the light emission end is ground into a plane. Certain angles are given to both ends or the prism 7 to make both faces unparall. The prism 7 is arranged between the end of the optical fiber 1 and the light reception element 2 so that these both faces cross the going direction or light. Light emitted from the end or the optical fiber 1 passes the prism 7 to change the going direction and is made incident on the light reception face of the light reception element 2 at a certain angle.  As the result, reflected light from the light reception face of the light reception element 2 has a certain angle, and the quantity of return light to the light incidence route is suppressed.

Abstract: PURPOSE:To remove a noise component, based on scattered light, so as to improve reliability by providing a measured visual field-changing optical element, changing a measured field of vision, being able to change an attitude in a light receiving optical system. CONSTITUTION:A parallel plain plate 18 functions as a measured visual field-changing optical element changing a measured visual field S in a manner wherein scattered light S, based on scattering of light in the vicinity S' of the measured visual field, is mainly guided to a photomultiplier (PMT) 9 serving as the photoconverter. When the parallel plane plate 18 is vertically set with respect to an optical axis O1 of a light receiving lens 7, the scattered light N from the measured visual field S mainly passes through an opening 8a of a diaphragm 8, being guided to the PMT 9, while scattered light N' from the vicinity S' of the measured visual field is partly guided.

An arithmetic circuit, being based on a photoconversion output from the PMT 9, calculates a measuring result in the measured visual field S and the measured visual field vicinity S', and protein concentration is accurately measured by removing a noise component contained in measurement in the measured visual field S.
