Title: Optical fiber bundle
Inventor: HOSONO SABUROU
IPC: G02B6/44
Filed: 1978-10-26
Abstract: PURPOSE: To eliminate the hindrance factors of transmittance at the end face of the optical fiber bundle by so constructing the same that the chipping of the end face thereof may be prevented at the time of forming the end face of the optical fiber bundle through polishing by covering a metal layer on the outside circumferential surface of the optical fiber bundle.  
     CONSTITUTION: Each optical fiber 2 is bonded to each other by adhesive agents 3 and the outside circumferential surface is covered with a metal layer 5. E.g., lead, tin, silver are used for the material of the metal layer 5. The end parts of the optical fibers 2 formed with the metal layer 5 are bundled and the adhesive agents 3 are poured, after which the end parts are cut and the surfaces are polished to complete the bundle. Since the outside circumferential surface of all the optical fibers 2 are covered with the metal layer 5, chipping of the end faces of the optical fibers does not occur even if the portions corresponding to the cavities of the adhesive agents are polished. Hence, the cause for the occurrence of a decrease in the transmittance of the optical fiber end face owing to chipping at the polishing may be eliminated.

Abstract: PURPOSE:To improve the load response speed and to respond to an instant load variation by providing flow control valves and highspeed opening/closing valves in a fuel feeding line and in an air feeding line, opening fully the control valves in the normal condition, and controlling the opening/closing valves to respond to the load variation. CONSTITUTION:A fuel gas 9 flows in a fuel electrode 2 through a flow control valve 5 and a high-speed opening/closing valve 7, while the air 10 flows in an air electrode 4 through a flow control valve 6 and a high-speed opening/ closing valve 8. The valves 5 and 6 are fully opened ordinarily respond to the full load of the cell, while the valves 7 and 8 are regulated in a throttled condition to respond to the present load. And when a signal to increase the load is input to a controller 13 from the load, the controller 13 opens the valves 7 and 8 instantly to feed the gas and the air to the cell. On the other hand, when a signal to decrease the load is input, the controller 13 operates to throttle the valves 7 and 8 instantly, and prevents the cell 1 from receiving the gas and the air more than the necessary amount. Consequently, the load response speed is improved, and the operation responding to an instant load variation can be carried out.

Abstract: PURPOSE:To enable a chromium mask pattern to be faithfully transferred onto a photoresist film by a method wherein the irradiation of the photoresist film with light is carried out a few times in succession, and the film is irradiated with light each time for a divided short time. CONSTITUTION:Photoresist is applied onto an Si substrate 1 and thermally treated to get firmly fixed to the Si substrate 1, whereby a photoresist film 2 is formed on the Si substrate 1. Then, a chromium mask 3 wherein an optical spot guide groove and a header signal are previously written as a monochromatic chromium pattern by a laser write device is brought into close contact with the Si substrate 1 provided with photoresist. The Si substrate 1 provided with photoresist is irradiated with ultraviolet rays 4 through the intermediary of the chromium mask 3 as the substrate 1 and the chromium mask 3 are kept in close contact with each other. At this point, the substrate 1 is irradiated with ultraviolet rays 4 a few times in succession, and each irradiation with rays is carried out for a divided short time, wherein a following irradiation follows a preceding irradiation after a prescribed interval. By this setup, nitrogen gas generated from the photoresist film 2 by the irradiation with ultraviolet rays is mode to flow out of the spot concerned. Thus, a mask pattern can be faithfully transferred onto a photoresist film.

Abstract: PURPOSE: To obtain a small valve provided with both functions of a relief valve and an anticavitation valve at a low cost, by allowing the pressure receiving are a on the pressure line side to be varied in relief valve operation and anticavitation valve operation.  
     CONSTITUTION: Between a poppet valve 36 and a lst valve seat 7, an intermediate body 42 is set which contacts with a first valve seat 7 and with which a valve 36 is contacted. When this valve operates as a relief valve, the liquid pressure in a pressure line 5a increases, and the liquid which flows in to a pressure chamber 41 forms pressure difference between a first passage 5 and the pressure chamber 41 by the operation of a pilot valve 29, and the pressure in the chamber 41 becomes lower than the pressure in the passage 5. At this time, the pressure receiving area on the line 5a side is the sum of the front end area of the valve 36, and the intermediate body 42, and the pressure receiving area on the chamber 41 side is the rear end surface of the valve 36. Therefore, when the pressure on the line 5a side exceeds the sum of the pressure on the 41 side and the pushing force of a spring 47, passages 5 and 6 are interconnected and pressure is released.
