摘要： PROBLEM TO BE SOLVED: To facilitate formation of a self-forming optical waveguide that has small transmission loss without using a solvent. SOLUTION: A first curing resin liquid 1 is filled in an acrylic transparent container 3 which is shaped to have an opening on the upper face of the rectangular parallelepiped and a plastic optical fiber is immersed, as shown in (a). The first curing resin liquid 1 is irradiated with a laser beam through the plastic optical fiber 4 and gradually hardened with the laser beam to form an axial core 5 through self convergence of light (b). From the opening of the transparent container 3, the uncured first curing resin liquid 1 is removed. In this case, the uncured first curing resin liquid 11 sticks to the surface of the core 5 and the inner face of the transparent container 3 and remains therein, as shown in (c). Then, a second curing resin liquid 2 is filled in the transparent container 3. In this case, the uncured first curing resin liquid 11 is dispersed in the second curing resin liquid 2. Thereafter, the second curing resin liquid 2 is photoset by ultraviolet rays to form a clad (d). COPYRIGHT: (C)2005,JPO&NCIPI

摘要： PROBLEM TO BE SOLVED: To form a core end of a self-forming optical waveguide having a branch, at a position as designed. SOLUTION: A wavelength selective mirror 30 is erected inside a transparent housing 10, with an optical fiber 20 inserted and filled with photo setting resin liquid 40 (4.A). The photo setting resin liquid 40 is irradiated with a laser beam λ w through the optical fiber 20 and hardened self-convergently to form a core 41. The core 41 grows to reach the wavelength selective mirror 30, with a part continued to grow along the reflected light downward as a core 41rf, and with a part along the transmitted light to the right as a core 41th (4.B). Before the core 41th reaching an optical port P3, the laser beam λ w is also introduced from the optical port P3 to an optical port P1, making the core start to grow also from the optical port P3, and making it integrated with the core 41th that passed through the wavelength selective mirror 30. Optical loss is found ≤0.3 dB at the junction between the core grown from the optical port P3 and the core 41th passed through the wavelength selective mirror 30. COPYRIGHT: (C)2007,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To form an optical waveguide having branches in a self-forming manner. SOLUTION: From a laser light source not shown, a laser beam 2 is converged by a lens 3 and guided to the incident end 10 of an optical fiber 1. With an LP 11 mode made to be emitted from an exiting end 11, dual-peak type light intensity peaks are arranged horizontally (1.A). Slide glass 4 covered with a gelatinized photosetting resin 5 film is disposed in the horizontal direction (1.B). When a laser beam of the LP 11 mode is emitted from the exiting end 11 of the optical fiber 1, a line of linear hardened object 61 starts forming (1.C). Now, with a lapse of time, a branch part 62 is formed at a position of a distance L from the exiting end 11 of the optical fiber 1, with growth followed in the form of two columnar hardened objects 63a, 63b. The two columnar hardened objects 63a, 63b are linear branches, wherein the angle formed thereby is about 4°. Thus, the optical waveguide 60 is formed comprising the hardened objects 61, 62, 63a, 63b (1.D). COPYRIGHT: (C)2007,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To provide a self-forming optical module in which a wavelength selective mirror is used. SOLUTION: The wavelength selective mirror 4 reflects a wavelength λ c1 , transmits a wavelength λ c2 and green light, and reflects red light. An end face 21 of the core of an optical fiber 2 is introduced into a housing 1 composed of transparent resin and is fixed with a fixing member 3 (3. A). Unhardened photosetting resin solution 5 of a high refractive index is charged inside the housing 1. When the photosetting resin solution 5 is irradiated with the laser beam of the wavelength λ c2 from the end face 21, a hardened product 50 is axially formed along the optical path (3. B). With the laser beam of the wavelength λ c1 is emitted from the end face 21, an axial hardened product 51 is formed in a branching manner (3. C). With the unhardened photosetting resin solution 5 removed (3. D), and with the unhardened photosetting resin solution 6 of a low refractive index charged inside the housing 1, all are hardened to form a clad 6c. A green optical element 70 is coupled with a red optical element 71, thereby forming the optical module 100 capable of two-color single-line bidirectional communication that functions on green and red light (3. E). COPYRIGHT: (C)2007,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To provide a fail-safe system of high reliability that is best suited for a plurality of arithmetic processing units interconnected via a network.
SOLUTION: The CPU of a gateway 1 (not shown) separates a damaged ECU 70 from a communications bus 27 and sends this information to other star couplers via the gateway 1 to control the star couplers to be kept out of communication with the ECU 70. The CPU 30 has a diagnostic bus 28 dedicated exclusively to the ECU 70 and an input/output control circuit 74 within the ECU 70 is separated from a microcontroller 73 and switched so that control can be effected from another input/output control circuit 64. The CPU 30 reads an alternative control program for the ECU 70 from a ROM 42 and performs alternative control of the damaged ECU 70 via the network.

摘要： PROBLEM TO BE SOLVED: To accurately measure an alcohol concentration in a breath by correcting influence of a vapor concentration.SOLUTION: Light emitted from a light source 10 is divided by a polarization beam splitter 13 into p-polarized light transmitted and s-polarized light reflected. The p-polarized light is reflected by an optical sensor element 11 and then reflected by the polarization beam splitter 13 so as to be output to a photodetector 15 as output light 1. The s-polarized light is reflected by an optical sensor element 12 through a quarter wave plate 14, passes through the quarter wave plate 14 again and passes through the polarization beam splitter 13 so as to be output to the photodetector 15 as output light 2. The optical sensor element 11 responds to an alcohol concentration and a vapor concentration to change its reflectance, and the optical sensor element 12 responds to a vapor concentration to change its reflectance. The intensity of the output light 1 is increased as the reflectance of the optical sensor element 11 is lowered, and the intensity of the output light 2 is reduced as the reflectance of the optical sensor element 12 is lowered.
