MAX1365 low power 4.5-digit panel meter integrate 20-bit Σ-Δ ADC,7-segment LED display driver,±15-bit voltage DAC and a 4 mA to 20 mA(or 0 to 16mA)current driver.
Ultrasonic treatment with higher power and shorter time or lower power and longer time could provide higher transformation rate. 22W×5min,33W×2min,44W×2min,44W×3min,55W×2min, 66W×1min were optimal;
Of a population of 5,389 former power-plant workers, 316 were characterized as individuals at highest risk for lung cancer according to a lung-cancer risk model including age, asbestos exposure and smoking habits.

In the spectrochemical analysis of high speed steels with a small current activated a.c. arc (after Aбрамсон), the results of analysis were found to be affected by different previous heat-treatments given to the steel samples. To study this effect we selected 10 chromium steel samples of different carbon content. Spectrochemical analysis of these samples under different procedures of heat treatment shows that with an a.c. arc (5 amp.) the results of analysis of Cr for annealed and for hardened samples of th...
1. An X-band E. S. R. spectrometer has been constructed. Its sensitivity is such that 3×10~(-8) mole of DPPH can be detected by oscilloscope with S/N=15/1. The five byperfine structure lines of 5×10~(-4) M/1 DPPH benzene solution have been resolved.
The method of correlation function has been utilized to discuss the nonlinear effects in the ferromagnetic resonance at high power levels. For ordinary ferromagnetic crystals, the present theory includes the results of the semiclassical theory developed by H. Suhl as a classical limit. In the case of YIG doped with rare-earth ions, the frequency shift and the additional losses due to the rare-earth ions have been discussed. Besides, the threshold field of the so-called first order process with parallel pump...
