Abstract: PURPOSE:To obtain crude zinc by means of distillation and separation of zinc and to recover iron and lead by means of specific gravity separation by pelletizing iron dust contg. high lead which is produced in an electric steel making process together with a carbonaceous reducing agent, melting and reducing the pellets. CONSTITUTION:The dust D contg. 25-30% Fe, 20-25% Zn and 3-4% Pb which is produced from an electric steel making factory is mixed with a carbonaceous reducing agent C such as coke and granulated to pellets Pe with a granulator 1. After removing the water from the pellets with a drier 2, these are stored and fed to a preheater 3 to be preheated and fed to a low frequency induction furnace 4 to reduce the oxides of Fe, Zn and Pb respectively. The reduced Fe is taken out as molten iron and desulfurized together with flux Fl in a desulfurizing furnace 5. The reduced Pb is separated from the molten iron by means of specific gravity difference and fed to a forging machine 7 as crude lead. The reduced Zn is evaporated and entered into a zinc condenser 8 together with gaseous CO and intermediately cooled with air A to be condensed as crude zinc for recovery.

Title: Recording and reproducing device
Inventor: OTSU MASAMITSU
IPC: G11B20/00
Filed: 1988-04-28
Abstract: PURPOSE:To improve deterioration in the quality of a sound signal due to an burst error by recording/reproducing a composite signal obtained by the time-axis compression and time-divided multiplication of a sound signal in the vertical blanking period of a video signal as it is without separating the composite signal into the sound signal and the video signal. CONSTITUTION:At the time of recording, a composite signal is modulated by the 1st means 2 to obtain a modulated signal appropriate for recording/reproducing and the modulated signal is successively time-divided in each fixed period and successively recorded on plural recording tracks by the 2nd means 19, 21 so that a video signal in one vertical period and sound signals before and after the video signal are recorded on one recording track and the same sound signal part is recorded on a recording medium 20 twice. At the time of reproducing, the recorded contents are demodulated by reproducing systems for two systems in the 3rd means 5, 6 so that the same sound signals can be reproduced simultaneously with the reproducing of the video signal. An error in these sound signals is detected by the 4th means 9, 10 to select a sound signal having no error and to obtain reproduced sound signals and a reproduced video signal. Consequently, an error ratio can be sharply improved and a device capable of resisting a burst error can be obtained.

Title: Image display device
Inventor: YOKOYAMA TOSHINOBU
IPC: H01J31/12
Filed: 1985-05-18
Abstract: PURPOSE:To prevent shaking of picture and fluctuation of brightness during display of image by extending a line cathode at the extension load region providing in common an extending member and a load member having a friction surface resulting in a frictional force required for showing the anti-vibration effect to the line cathode. CONSTITUTION:When a pulse voltage is applied to a line cathode 11 to emit hot electrons, a current flows for a very short period, the line cathode 11 expands thermally and the natural frequency of line cathode 11 changes. When the natural frequency becomes almost equal to the period of pulse, the line cathode resonates. Friction which is sufficient for resulting in anti-vibration effect is given to the extension load region of line cathode 11 and vibration energy of line cathode 11 can be absorbed by friction by loading between a load case 13 and a spacer 18, and between a load axis 17 and a spacer with a low load spring 20 for spacer and a spring 21 for load axis, and thereby vibration amplitude of line cathode which has been + or -20-200mum can be reduced to + or -20mum or less even in maximum. Accordingly, a high grade picture without shaking and fluctuation of brightness can be obtained.

NO in the gas is collected by adsorption at 5-40 deg.C (room temperature may be preferable) by the body 4. A fixed quantity of the collected manganese oxide is weighed in a platinum boat and weighed manganese oxide is heated at 800 deg.C in a gaseous H2 current. Then, generated NH3 is absorbed in a collection liquid and the coulometric titration is performed. Manganese dioxide for an elemental analysis available on the market is used for said manganese oxide. In this manner, the measurement of extremely minute quantity of the NO is made possible.
