Abstract: PROBLEM TO BE SOLVED: To attain size reduction and a high image quality by providing a second cylinder, which has an opening on the filter side and is cooled to the almost same temperature as a tip part of a second inner cylinder, on an infrared ray detecting element. SOLUTION: A first inner cylinder 4 is joined to a stand 1 of an end part of an outer cylinder 2 joined to a window 3 to pass infrared rays. A second inner cylinder 5 is joined to the other end of a disk 6 joined to an end part of the first inner cylinder 4, and an infrared ray detecting element 7 is arranged in its tip part. A filter 9 to pass only a selected wave length is joined to an opening part on the window 3 side of a first cylinder 8.

Abstract: PURPOSE:To improve the efficiency of hydrogenation of a polysilicon thin-film by providing a hydrogen atom diffusion preventive film on an overcoat film, and applying annealing treatment in this condition thereby breaking away hydrogen atoms from the overcoat film and making them couple with the dangling bond of the polysilicon film. CONSTITUTION:An overcoat film 8 consisting of a plasma silicon nitride film is stacked, and then a hydrogen atom diffusion preventive film 9 consisting of a high melting point metal such as chromium, etc., is stacked on the topside of the overcoat by sputtering.

Abstract: PURPOSE:To obtain a wide band and to increase a variable gain range by connecting an element for gain variation in series to the input side of a transistor (TR) amplifying circuit, and then varying the impedance of said element for gain variation. CONSTITUTION:On the base side of a TR, a resistance R5 and a DC-stopping pass capacitor C3 are provided, and the value of the resistance R5 is made much less than the sum of the impedance of a pin diode D and the impedance R1 of an input signal source so that impedance when the input side of the TR is viewed from the base side never varies with the impedance of the pin diode D. Consequently, even when the pin diode D varies in impedance, the frequency characteristics of a TR amplifying circuit never vary. Therefore, a variable gain circuit D has a wide band and a >=15dB wide variable gain range in a 1.2GHz frequency band by utilizing impedance variation attained by varying a current flowing the pin diode D by the R5.
