Filed: 1982-05-25
Abstract: PURPOSE:To realize a quantitative analysis of Mo with extremely high accuracy without being affected by a coexisting element, by applying a fixed dissolution method to a sample to be analysed. CONSTITUTION:At the time of performing a quantitative analysis, a sample to be analysed such as a voltage nonlinear resistor which consists essentially of e.g. ZnO and contains Mo, is finely, pulverized, Hereafter, this pulverized sample is dissolved by using HCl and next, PbSO4 is produced by adding H2SO4 and is separated. Moreover, a very small amount of Pb is masked by tartaric acid. Next, the quantitative analysis of the quantity of Mo in the sample treated in said way is performed by using a plasma emission spectrochemical method. By analyzing in said manner, the quantity of Mo in the sample is determined quantitatively with good accuracy because the influence of viscosity is eliminated by adding HCl, H2SO4 and tartaric acid to the sample and Mo is dissolved by restraining the deposition of Pb.

Abstract: PURPOSE:To improve the effect of prevention of video recording failure such as erroneous recording or erroneous erasing of a cassette, by detecting the presence/absence of an erroneous erasion preventing chip immediately after the generation of a video recording instruction signal and returning the recording medium to a stop mode, if the result of detection shows the absence independently of the present operating mode. CONSTITUTION:When an operating command signal C from an operating command input circuit 9 enters a microcomputer 8, it discriminates whether or not the signal is a video recording command signal, and when this is the recording instruction signal, the presence/absence of an erroneous erasion prevention chip is discriminated with a detection signal A for the presence/absence of the erroneous erasion preventing chip. When the chip is existing, the magnetic tape run state is set to the video recording state as instructed by the signal C, and if no chip is presented, the present magnetic tape run state is descriminated. When the state is the reproduction state, the tape run is stopped after unloading, and if in other states, the tape run is immediately stooped.
