Title: Production of fused flux for submerged arc welding
Inventor: OKUDA NAOKI
IPC: B23K35/362
Filed: 1989-02-10
Abstract: PURPOSE:To allow the use of low-grade Mn ore having high contents of FeO and P by adding a specific ratio of a carbon material having a specific grain size to flux raw materials, dissolving the raw materials at the specific value or above of the ratio of a dissolving current and a dissolving voltage and producing flux. CONSTITUTION:The carbon material of 0.149 to 1.68mm grain size is added at 1 to 3wt.% in terms of C to the flux raw materials and the raw materials are melted by setting the ratio A/V of the dissolving current A and the dissolving voltage V at >=26. The carbon material is added to the low grade Mn ore in order to reduce away the FeO and P contained in this ore in a dissolving stage. The carbon material is sucked to dust collecting equipment at the time of the addition when the grain size is smaller than 0.149mm and the carbon material remains as it is in the flux and leads to a weld crack when the grain size is larger than 1.68mm. The local reduction of the molten metal surface progresses and the sufficient removal of the impurities is not possible when the A/V is below 26.

Abstract: PURPOSE:To facilitate the discrimination of a welding portion by providing a peel-off portion of a protective tape at a position corresponding to the welding portion. CONSTITUTION:A protective tape 3 is stuck to the surface side of a metal plate 1. In this case, the protective tape 3 at a position corresponding to a welding portion 23 connecting the metal plates 1 together is peeled off 24 over a range (1), thereby the surface of the metal plate 1 is exposed.

SOLUTION: A laser beam of a specified frequency is irradiated from a laser blood blow meter 1 to the skin of the human body and the blood flow rate flowing in the skin blood vessel is measured based on the intensity of the reflected beam. This measured data is input in an FET analyzer 2, high speed Fourier transform is applied on the measured data of the skin blood flow rate, and frequency components of the variation in the skin blood flow rate are analyzed. Prescribed peak value of the frequency components, for example, 0.05Hz-0.3Hz is detected, compared with a prescribed threshold, and the awareness is judged according to the measurement data. Namely, when the peak value is less than the threshold, it is judged to be an awareness, and when the peak value is more than the threshold, it is judged to be a sleeping state.

Abstract: PURPOSE:To reach a final perfect focal point, that is, a perfect astigmatism correcting position with smaller trial and error for improving an S/N by finding a value near the optimum value of an astigmatism correction coil current value. CONSTITUTION:Correction currents Ix and Iy to be made to flow to two sets of astigmatism correction coils are set up at certain values for scanning on an sample S in the direction (a) only once by an electron beam probe and integrating the differential value of a detection signal of a secondary electron image or the like during one time scanning and this integration value is A/D converted after the end of scanning in order to be memorized. While making mutual change between Ix and Iy in turn, scanning is repeated only in the direction (a) for finding combination Ix1 and Iy1 of the astigmatism correction coil currents giving the maximum value. Next, scanning is performed on the sample S in the direction (b) crossing the direction (a) at a right angle for finding a combination Ix2 and Iy2 of the astigmatism coil currents similarly giving the maximum value. In this ways, a value near the optimum value is found. Thereby, the final perfect focal position that is, the perfect astigmatism correction position can be reached with smaller trial and error so as to be able to improve an S/N.
