Title: Gas blast-circuit breaker
Inventor: YOSHIDA MIHO
IPC: F17D5/00
Filed: 1996-10-29
Abstract: PROBLEM TO BE SOLVED: To provide a gas blast-circuit breaker for performing prohibiting setting in which a gas cutoff valve is not closed by detection of abnormalities by an external sensor in inspection of the flow rate detecting operation. SOLUTION: In a gas blast-circuit breaker provided with a structure for performing the gas cutoff operation by detection of the flow rate and detection of abnormalities of the outside, setting in which the gas cutoff operation by an external part abnormality judging part 6 in inspection of the flow rate detecting operation is performed by a control signal to be input from an external communication part 3 by communication. When the external part communication part 3 receives the control signal, an external part input control part 4 performs prohibition setting of the judging operation of the external part abnormality judging part 6.  Since the prohibition setting is released when a flow rate judging part 7 outputs a cutoff request signal, the inspection of the flow rate detection can be performed without being affected by the gas cutoff operation by the external part abnormality judgement.

IPC: G02B6/34
Filed: 1990-10-24
Abstract: PURPOSE:To prevent the generation of foam in an adhesive agent in the process of hardening by forming a prism of a dielectric whose refractive index is higher than that of an optical waveguide layer, and fixing it to a gap layer having a refractive index being lower than that of the optical waveguide layer by a photohardening type adhesive agent having a refractive index being higher than that of the optical waveguide layer. CONSTITUTION:On a substrate 1, an optical waveguide layer 2 is formed, and also, a gap layer 3 having a refractive index being lower than that of the optical waveguide layer 2 is formed thereon. On the gap layer 3, a prism 4 formed by a dielectric is fixed by a photohardening type adhesive agent 5. The prism 4 and the photohardening type adhesive agent 5 have a higher refractive index than that of the optical waveguide layer 2. In such a way, foam does not exist in the hardened adhesive agent, and the light whose beam diameter is large can also be subjected to optical coupling with the optical waveguide layer with high efficiency. Also, since hardening of the adhesive agent is executed by light irradiation, the prism can be joined in a short time, and the efficiency of manufacture is improved.
