摘要： Provided is a heat insulating structure for a cylindrical pipe, wherein the heat insulating structure can suppress formation of a large gap between a pair of heat insulating members arranged adjacent to each other in the axial direction of the cylindrical pipe. On the outer periphery of the cylindrical pipe through which a low temperature fluid flows, a heat insulating wall is provided. The heat insulating wall is composed of a plurality of cylindrical layers having different diameters, and each of the cylindrical layers is formed of circular-arc heat insulating members (P) divided in the circumferential direction of the cylindrical pipe and the axial direction of the cylindrical pipe. With respect to the pair of heat insulating member (P) aligned adjacent to each other in the axial direction of the cylindrical pipe in at least a heat insulating wall on the inner side in the radial direction of the cylindrical pipe among the plurality of layers of the heat insulating wall, a connecting member (W) having a pair of locking portions (Wa) is provided so that the pair of locking portions (Wa) are separately inserted inward in the radial direction of the cylindrical pipe into the outer surface portions of the pair of heat insulating members (P).

摘要： A gas visualizing apparatus includes an image sensor 4 for detecting infrared light radiated or reflected from a background of a gas leak monitoring territory A, a laser source 3 for emitting a detection infrared beam in two-dimensional form toward the gas leak monitoring territory A, the detection infrared beam having a wavelength absorbable by a gas "g" to be detected, and a CRT 6 for displaying information relating to gas leakage as a two-dimensional visible image corresponding to the gas leak monitoring territory A. The laser source 3 includes a beam expander 7 for converging or diverging the detection infrared beam to vary an area of the gas leak monitoring territory A. The image sensor 4 includes a transmission bandwidth varying device 9, 10 for setting a band of the infrared light entering the image sensor 4 to a band substantially centering on the wavelength of the detection infrared beam, and varying a width of the band, to realize an excellent visible image.

摘要： PROBLEM TO BE SOLVED: To provide a low temperature-protective wear having no problems of freezing of a cloth/fabric even a warm liquid comes to contact with the cloth, capable of selecting specifications depending on working conditions and environments, having no problems of damaging even in contacting with a very low temperature-liquid and excellent in durability. SOLUTION: A water repelling process with a silicone resin 32 is applied to or a synthetic rubber layer is installed to the face side background 31 of an outer fabric 14 and a removable inner fabric 15 is fitted to the outer fabric 14 by a slide fastener. The inner fabric 15 includes an outer lining fabric 34, a middle fabric 36 and an inner lining fabric 37. When a very low temperature-liquid is brought to contact with the said process-applied face side background 31, the liquid rolls down in a spherical shape. Even when the very low temperature liquid is brought to contact with the face side background 31 applied with a rubber layer, the liquid does not penetrate into the face side background. The fabric is never frozen even under a moist environment. By preparing the inner fabrics having different thickness of the middle fabric 36, you can choose them depending on using conditions. As the outer fabric 14 and the inner fabric 15 are removable in wearing, it is easy to repair and wash either one of them when it is broken.

摘要： PROBLEM TO BE SOLVED: To obtain a method for controlling calorific values capable of continuously controlling calorific values in real time on a manufacturing line. SOLUTION: In the case of controlling the calorific value of a product gas formed by adding a calorific-value regulating gas of higher calorific value than that of a base gas with methane as its major composition into the base gas to a target calorific value, a sound velocity-calorific value relating index to be obtained from the relation between the velocity of sound and the calorific value of each of a plurality of standard gases formed by mixing the base gas and calorific value regulating gas in different proportions is obtained in advance. Then the velocity of sound in the product gas is obtained, and from the obtained velocity of sound in the product gas, the calorific value of the product gas is obtained on the basis of the sound velocity-calorific value relating index. In addition, the amount of a calorific-value regulating gas raw material added into a base gas raw material is regulated on the basis of the difference between the obtained calorific value of the product gas and the target calorific value.
