Title: Emergency leakage preventive valve
Inventor: KANZAKI YASUO
IPC: F16K17/34
Filed: 1996-12-11
Abstract: PROBLEM TO BE SOLVED: To surely prevent the leakage by sliding a valve disk in the outlet direction against the resistance of a steel ball pressed by a pressing means to close a valve and rapidly stop the flow of the fluid when a breakage occurs in the fluid system and the differential pressure between the inlet side and the outlet side of the valve disk is rapidly increased. SOLUTION: In the normal working condition, the fluid flows from the inlet side to the outlet side through a piercing flow passage 11 of a valve disk 3. In this condition, when a breakage occurs in the fluid system on the outlet side of an outer cylinder, and the differential pressure between the inlet side and the outlet side of the valve disk 3 is rapidly increased, and the differential pressure exceeds the resistance of a steel ball 7 pressed by an elastic pressing means, the valve disk 3 slides in the outlet side direction. When an inlet side end face of an inner cylinder 20 is abutted on an outlet (f) part of the piercing flow passage 11 by the movement of the valve disk 3, the flow of the fluid is stopped.  The moving speed is regulated to be optimum by the restoring force of a coil spring 13 and the resistance of the fluid flowing in a flow passage 21 from a buffer solution storage tank 12 part which is regulated by advancing/ retracting a regulating needle valve 8.

Title: Optical resonance type filter
Inventor: KONDO KENTARO
IPC: G02B5/28
Filed: 1988-12-29
Abstract: PURPOSE:To provide a filter characteristic which allows the transmission of only the single frequency by using a light transparent structural body which generates Bragg reflection to form at least one of a pair of translucent mirrors which constitute a Fabry-Perot interferometer. CONSTITUTION:InGaAs layers 2 and InP layers 3 are alternately laminated on a substrate consisting of an InP single crystal 1. The respective thicknesses of the layers are 1/4 the wavelength of the light to be transmitted, i.e. lambda/4. The refractive index distribution of the structural body is periodic and the respective thicknesses is lambda/4; therefore, the Bragg reflection takes place in the same manner as with a distribution feedback type semiconductor laser. Namely, of the incident light from the surface 4 side, only the light of the wavelength satisfying the Bragg condition with respect to the periodic structure reflects in the incident direction. If the surface 4 is finished to a smooth specular surface, the light arriving there from the InP side reflects on this surface and is made incident again to the periodic structural part. The repetition of such reflections takes place only with the specific wavelength light. The characteristic which resonates only to the light of the single wavelength is obtd. in this way.
