Filed: 1996-02-01
Abstract: PROBLEM TO BE SOLVED: To clearly observe feeble stellar light which cannot be observed because it is mixed with background light by arranging a band-pass type optical filter transmitting the observation light of narrow-band wavelength being an object to be observed in front of a digital type camera. SOLUTION: The band-pass type optical filter 3 transmitting observation light of the narrow-band wavelength being the object to be observed is arranged between a telescope 1 and the attached digital type camera 2. Then, solar light being the background light and the scattered light thereof are eliminated or the light quantity thereof is reduced so as to observe the feeble light (it means feeble compared with the background light) which cannot be observed because it is normally mixed with the background light. In such a case, an interference filter consisting of a band-pass type multilayered dielectric thin film through which the light of the wavelength of a dark line called Fraunhofer(HF) line generated by the light absorption of some kind of element existing in solar atomosphere is transmitted is adopted.  By selecting the wavelength of the observation light by using the interference filter, only an aimed star can be observed and the super-nova investigation in sky in the daytime is drastically improved.

Filed: 1982-02-04
Abstract: PURPOSE:To effectively correct even air-fuel ratios during high-land running period by correcting the dispersions of a vortex flow meter to detect the flow rate of intake air and also of fuel metering. CONSTITUTION:Fuel sent under pressure is injected into an air inlet pipe 3 syncyronously with the frequency output of a vortex flow meter 4.

Title: Method for estimating positional shift between optical connectors and method for inspecting characteristics of guide pinhole of optical connector
Inventor: ISHIDA HIDETOSHI
IPC: G01B21/00
Filed: 1993-02-04
Abstract: PURPOSE:To provide a method for estimating the relative positional shift between optical connectors at the time of coupling thereof based on the coupling loss. CONSTITUTION:The coupling loss between a pair of optical fibers 7, 8 is determined when they are coupled through a connector and then the axial shift between cores is determined based on the coupling loss thus determined. On the other hand, the eccentricity of the core is measured for each fiber in optical connectors 1, 2 and the axial shift between cores is determined when one optical connector is imaginarily shifted from the other optical connector based on the measurement of eccentricity of the core. An imaginary positional shift is then determined for the case where the axial shift of core determined based on the coupling loss matches most with the imaginary axial shift of the core. The imaginary positional shift thus determined is estimated as the actual relative positional shift between the optical connectors.
