摘要： PURPOSE: To obtain a highly rigid gas analyzer excellent in sensitivity and various advantages including high selectivity for various components to be measured are realized through simple structure. CONSTITUTION: The gas analyzer comprises a light source 34 emitting infrared luminous flux, a sample cell 38 being fed with a sample gas and disposed such that the infrared luminous flux from the light source 34 passes through the sample gas, and means 10a, 10b encapsulating an absorber disposed such that the infrared luminous flux passed through the sample cell 38 further passes through the absorbing body and optically detecting a pressure rise caused by temperature rise in the chamber encapsulating the absorber when the infrared luminous flux is absorbed by the absorber in order to measure the concentration of objective component of sample gas based on the pressure rise. In such gas analyzer, a gas of same components as those to be measured is employed as the absorber encapsulated in the detection means 10a, 10b.

摘要： PURPOSE:To obtain a gas-inflation type energy-measuring device with a high measuring accuracy. CONSTITUTION:A title item is provided with a small chamber 2 incorporating an absorption film 3 which absorbs a cast electromagnetic energy and a flexible film 8 which is fitted so that it covers an opening which is formed at the other end face of the small chamber and an amount of inflation of the flexible film 8 changes according to the amount of electromagnetic wave energy which is absorbed by the absorption film 3. Then, a device which detects the amount of inflation of the flexible film 8 consists of a light source 16 which casts a flux of light, a plane reflection mirror 18 which converts a light path of a flux of reflection light which is reflected by the flexible film, a two-division photoelectric detection device 19 with first and second photoelectric detection elements 19a and 19b which receive the flux of light which is reflected by the plane reflection mirror 18, and a differential amplifier 20 which detects an output voltage difference of both detection elements 19a and 19b. Then, an equal amount flux of reflection light is cast to each of both detection elements 19a and 19b when no electromagnetic wave is cast.

摘要： PURPOSE:To obtain an excellent heat-generating characteristic and an excellent light-emitting characteristic by using a small-diameter ceramic. CONSTITUTION:A ceramic heat-generating body 10 is formed in the following manner: a molybdenum silicide slender wire obtained by the extrusion molding method of a finer ceramic powder by using, e.g. a water binder method is wound to be a coil shape; and it is dried and baked in a vacuum baking furnace. As a result, a small-diameter ceramic wire which is comparatively long can be former as the heat-generating body 10, and its resistance can be enhanced largely. When an electric current is supplies to the coil-shaped ceramic slender wire 10 via lead wires 12a, 12b, infrared rays which are radiated from the slender wire 10 are radiated via a radiation window 14.

摘要： PURPOSE:To obtain a Fourier conversion spectrophotometer capable of obtaining spectrum data with good stability. CONSTITUTION:By using a Fourier conversion spectrophotometer, interference light is split into two by a beam splitter 18 and one of them is input to a sample detector 24 by way of a sample 28 and the other is to a reference detector 26 and therefore, each of interference lights with and without passing a sample can be detected in the same conditions. And by Fourier converting each interferogram with a Fourier conversion means 12 and subtracting the reference spectrum from the sample spectrum with a subtraction means 14, only spectrum data origined from the sample can be collected. As the conditions, etc., in an interferogram producing means during collecting the sample spectrum and the reference spectrum are constant, the stability of the data is very good.

摘要： PURPOSE:To decrease the secondary mixing of separated components in eluate by vertically arranging an enriching rod whose surface has a smooth conical shape and end part at the large-diameter side has a protruding shape with the large-diameter side upward, and supplying the eluate from the upper part. CONSTITUTION:An enriching rod 10 whose surface has a smooth conical shape and end part on the large-diameter side has a protruding shape is vertically arranged with the large-diameter side upward. Eluate from the column of high performance liquid chromatograph is supplied through a supply tube 24. Then, the eluate wets the entire surface of the rod and flows down by its own weight. At this time, solvent is evaporated. When the eluate is enriched and the enriched eluate reaches the lower end of the rod 10, a liquid droplet 40 is formed. When the droplet 40 becomes the adequate size, it falls down. The amount of the falling liquid droplet 40 is determined by the physical properties such as viscos ity or surface tension and the like and the diameter of the lower end of the rod 10. Infrared rays are projected on the fallen liquid droplet 40 from a spectro scope 44, and infrared spectroscopic measurement is performed. Thus the secon dary mixing of the separated components in the eluate can be decreased.

摘要： PROBLEM TO BE SOLVED: To measure total reflection easily using a microscope. SOLUTION: The convex surface of a plano-convex lens 32c in nearly a hemispherical shape is allowed to oppose a Cassegrainian mirror 10, where a concave surface mirror 12, where a hole 12a is formed at the center part and a convex surface mirror 14, whose diameter is smaller than that of the concave surface mirror 12 are arranged oppositely while matching center axes C with each other, the center axis of the plano-convex lens is made to match with the center axis C of the Cassegrainian mirror 10, and a sample 30 is brought into contact with the plane of the plano-convex lens. In this state, luminous flux from the hole 12a is applied and is reflected successively from the convex surface mirror and the concave surface mirror, and is converged to the plane center point of the plano-convex lens at an incidence angle that is equal to or larger than a critical angle. Total reflection light is reflected successively from the concave surface mirror and the convex surface mirror and total reflection light emitted from the hole 12a is detected.
