A novel thin ITO film formed on a substrate and containing Sn at a concentration of 0.6 to 2.8 atomic %. The thin ITO film can be used as a transparent electrically conducting film. A method of producing the thin ITO film includes a step of spraying a mixed solution of an indium salt and a tin salt onto a substrate left in the atmosphere. A stannous chloride is used as the tin salt and an alcohol solution is used as the solution. The thin ITO film of a low Sn concentration (0.6, 1.3 or 2.8 atomic %) exhibits a markedly decreased absorption coefficient in a long wavelength region (lamda 500 to 1000 nm). The thin ITO film realizes a low resistivity (about 1.7 x 10<-4> omega.cm).

A method of fabricating light emitting diodes (LED) with a colour purifying diffraction lattice (CPDL) is suggested, the essence of the invention is in the use of the coherent scattering of the light by the CPDL for colour purifying of the light emitted by the LED and enhancement its extraction efficiency, the CPDL is a hexagonal two-dimensional periodical pattern on the surface of the LED structure or an internal interface resulting in the periodical variation in the refractive index with the period d The period of CPDL satisfies the equation d=m.lamda. / n, where m is a positive integer number, .lamda. is the wavelength of the light generated by LED, and n is the refraction index of LED structure. The height of the hexagonal islands forming CPDL is h=.lamda.(2l+1) / 2n, l is a positive integer number or zero. Use of CPDL allows to convert the laterally propagating light into the vertically propagating and simultaneously filter its spectrum.

The signal modulating scale pattern includes a coarse periodic pattern component as a function of position along the scale having a spatial wavelength [lamda]C, wherein nx[lamda]C=R and n is an integer, and a fine periodic pattern component as a function of position along the scale having a spatial wavelength [lamda]F, wherein (mn+1)x[lamda]F=R and m is an integer that is at least two. The wavelengths [lamda]C and [lamda]C may be widely separated.

The invention relates to a method and a device for generating a test program for verifying the function of a microprocessor. The method comprises the following steps of: A, randomly generating mu+lamda individuals, saving the individuals as an original generation population, and taking the original generation population as the current population; B, converting the individuals in the current population into the test program by combining an instruction library; C, performing simulation execution on the test program obtained by converting each individual in the current population to generate a functional coverage report; D, directly performing the step E if the current population is the original generation population, and performing intersection and variation operation on the individuals in the current population for lamda times, saving the generated new individuals in the current population, and performing the step E if the current population is not the original generation population; E, selecting at least mu individuals from the current population as a new-generation population according to the functional coverage report; and F, outputting test program sets corresponding to the individuals in the new-generation population if the stop condition is met, and taking the new-generation population as the current population and returning to the step B if the stop condition is not met.

A stable fuel supply system in a fuel cell system produces heat and electricity by combining hydrogen modified from a major raw material selected from various hydrogen compounds, with oxygen existing in air. A fuel supply device and a fuel supply method in a fuel cell system, which automate a steam to carbon ratio (S / C) control and a lamda control, and achieve a fuel cell system operation efficiently and stably coping with pressure loss and pulsation occurring within the system, while using a minimum number of balance-of-plant (BOP) units. A method more efficiently and precisely supplies fuel during the start-up and operation of the fuel cell system, while preventing flame failure of a burner and maintaining an appropriate carbon monoxide concentration even when an abrupt flow rate variation occurs. Also, an operating method improves functions associated with a decomposition ability based on selection of the specification of a fuel pump, and thus, is more economical and stable in terms of the costs and configuration of the fuel cell system.
