Abstract: A method, apparatus, system, computer program and medium, for inspecting a wide variety of circuit boards. A controller generates test data and reference data according to characteristic information of a circuit board. Using the test data, the circuit board generates processed data. A comparator compares the processed data with the reference data on a bit-by-bit basis. Based on the comparison result, the comparator determines acceptability of the circuit board. In addition, the comparator is capable of specifying a specific portion of the circuit board causing a defect.

Abstract: A cooling structure of a combustor tail tube is capable of avoiding the formation of cracks in the tail tube by lessening thermal stress and preventing thermal deformation, thus extending the service life. A multiplicity of cooling jackets (5) extend in the longitudinal direction of the tail tube of a gas turbine combustor along the entire circumference of the tail tube wall. The passage sectional area of the cooling jackets (5) is varied depending on the metal temperature of parts of the tail tube (4). For example, the passage sectional area of the cooling jackets (5) formed at the rotor side wall and the mutually opposite side walls of the adjacent tail tube is larger than the passage sectional area of the cooling jackets (5) formed at the casing side wall.

Abstract: A data library, a CPU and a memory store a design aid program which designs power supply circuit diagrams based on the data library in accordance with given conditions for a power supply circuit. Therefore, design errors associated with an increased design scale are prevented and the design time is shortened. The given conditions are taken as the respective vertical and horizontal intervals between power portions having first pins for connecting to a power supply and second pins for connecting to earth, and the number of rows and the number of steps of the power portions. Then, multiple available power portions are arranged according to the given conditions by a design aid program and the multiple arranged power portions are wired to a power supply symbol and an earth symbol, respectively.

Abstract: A dyed union knit fabric comprised of at least a polyurethane elastic fiber containing a chlorine-induced degradation inhibitor in a proportion of 0.5-4.5 weight % relative to the weight of the fiber, and a polyamide fiber and/or a cation dyeable polyester fiber, which has been dyed with mixed dyes of acid dyes, dispersion dyes, metal-complex dyes, reactive dyes and direct dyes, and markedly improved in resistance to chlorine-induced change in shade by allowing to contain at least one compound having a reaction amount of chlorine of 50 milliequivalent per gram or more, specifically one member of mono- and/or polyhydroxybenzene derivatives in a proportion of 0.1-20% relative to the weight of the fiber; and a method for manufacturing same. According to the present invention, excellent resistance to chlorine-induced change in shade as well as chlorine-induced degradation can be afforded to the dyed union knit fabric.
