摘要:
An infrared ray detector assembly for detecting a plurality of components such as hydrocarbons, CO.sub.2 and CO gases includes a housing member having a hollow interior and a portion transmissible to infrared rays and a holder member mounted within the hollow interior and having a plurality of separate compartments. An infrared detector is mounted in each compartment, and an optical filter is mounted over each compartment, abutting adjacent filters to respectively limit the wavelength band to each infrared detector, each optical filter having a substrate of approximately the same material and thickness.
摘要:
A measuring instrument that must transmit predetermined wavelengths of optical radiation has an optical filter assembly that can be conveniently manufactured. The optical filter assembly can be coated to provide optical coatings on either side of the substrate, and a masking layer can be deposited to encompass the peripheral edges of the optical coatings and exposed portions of the substrate to eliminate the problem of optical noise resulting from optical radiation contact with the edges of the coating layers.

An electron-emitting device comprises a pair of oppositely disposed electrodes and an electroconductive film arranged between the electrodes and including a high resistance region. The high resistance region has a deposit containing carbon as a principal ingredient. The electron-emitting device can be used for an electron source of an image-forming apparatus of the flat panel type.

An electron-emitting device comprises a pair of electrodes and an electroconductive film arranged between the electrodes and including an electron-emitting region carrying a graphite film. The graphite film shows, in a Raman spectroscopic analysis using a laser light source with a wavelength of 514.5 nm and a spot diameter of 1 μm, peaks of scattered light, of which 1) a peak (P2) located in the vicinity of 1,580 cm−1 is greater than a peak (P1) located in the vicinity of 1,335 cm−1 or 2) the half-width of a peak (P1) located in the vicinity of 1,335 cm−1 is not greater than 150 cm−1.

摘要:
A method of manufacturing an electron-emitting device has a step of forming a pair of conductors on a substrate, the conductors being spaced from each other, and an activation process of depositing carbon or carbon compound on at least one side of the pair of conductors in an atmosphere of carbon compound gas. The activation process includes a plurality of processes of two or more stages including a first process and a second process. The first process is executed in an atmosphere of the carbon compound gas having a partial pressure higher than a partial pressure of the gas in the second process, with the second process being the last activation process.

摘要:
In a method for measuring a specified component in a specimen by reacting the specimen with a first reagent formed by binding a substance active to the specified component, with carrier particles and a second reagent formed by labelling a substance active to the specified component with a first label, and measuring the substances in the complexes obtained in the reaction, there is disclosed a method featured by labelling the carrier particles with a second label different from the first label, and detecting the second label and then the first label utilizing the detection of the second label as a trigger.This method enables a highly precise measurement without the influence of noise components in the detection of specified trace components in the specimen, utilizing an antigen-antibody reaction or a nucleic acid hybridization.
