Title: Improvement in or pertaining to detection of ultraviolet rays
Inventor: JIEIMUZU HENRII NOBUSU
IPC: G01J1/44
Filed: 1988-05-02
Abstract: PURPOSE: To monitor ultraviolet rays regardless of the temperature and the intensities of infrared rays and visible light rays by providing an appropriately selected filter which emits fluorescence of the quantity corresponding to the quantity of ultraviolet rays when the filter is exposed to the ultraviolet rays. CONSTITUTION: A measuring head 101 has a bisected brass casing 110 having openings 101 and 111 both surfaces as the incoming and outgoing passages of ultraviolet rays. A fluorescent filter (long-passage glass filter) 112 which emits fluorescent proportional to the quantity of ultraviolet rays when the filter 112 is exposed to the ultraviolet rays is fitted between the openings 101 and 111. The fluorescence is transmitted to a photodiode detecting unit 104 through an optical fiber cable 103, converted into a voltage of the magnitude corresponding to the intensity of the fluorescence, and transmitted to a display unit and a power source 105. In addition, a thermistor 105 is incorporated in the head 101 and compensates the temperature corresponding to the intensity of the fluorescence. Moreover, an interference filter 118 is contained in the cable 103 so that only the fluorescence having a selected wavelength can be received by means of the photodiode 104 for monitoring.

Title: Optical fiber switch
Inventor: SANO KATSUHIKO
IPC: G02F1/313
Filed: 1986-05-13
Abstract: PURPOSE:To improve switching characteristics with a simple structure by surrounding plural cores optically coupled with one core with a clad consisting of liquid crystal and selecting an optical signal transmission line only by controlling the supply of an electric field. CONSTITUTION:One optical fiber 1 and plural optical fibers 3, 4 are formed and an optical signal from a light emitting source is transmitted to a light receiving part through the optical fibers. The clad part 5 of the optical fibers 3, 4 optically coupled with respective light emitting sources is constituted of liquid crystal whose refractive index is changed to a state larger than that of the optical fiber core and a state smaller than that. When a positive voltage is impressed to an electrode 6 by a voltage device 9, the refractive index of only the liquid crystal positioned between the electrodes 6, 8 is increased larger than that of the fiber 4. Thereby, an optical signal transmitted through the fiber 4 is transmitted to the outside through the clad 5 and an optical signal transmitted through the fiber 3 is transmitted to the fiber 1. Thus, the switching characteristics can be improved.

Abstract: PURPOSE:To utilize a circuit effectively by using a paging channel as an emergency radio channel. CONSTITUTION:A radio terrestrial station 1 and a general moving body 2 comminicate with each other on a paging channel P and a calling channel S. In the figures, 3-3'' are areas that the radio base station covers, and 5 is a moving body in an emergency. When there are many free channels in the areas 3-3'', specific channel assignment for emergency is not performed specially. When, however, free channels decrease in number, the number of general channels is decreased to increase the number of specific channels for emergency. Namely, once a specific channel flag for emergency is used, another channel is assigned newly as a specific channel. Further, when a free channel is only the paging channel, the paging channel itself is designated as the specific channel for emergency.
