Title: Solvent recovery method
Inventor: MIURA MITSUGI
IPC: B05C9/14
Filed: 1978-08-19
Abstract: PURPOSE: To easily maintain the gas in the dryer alwats at a safe oxygen concentration free from risk of explosion, by removing the oxygen contained in the gas at a high yield.  
     CONSTITUTION: The gas in a dryer 1 is taken out from a gas exhaust pipe 6, and is passed through a high temperature dehumidifying agent layer 14 such as molecular sieve to separate the steam content by adsorption, and is then condensed in a condenser 7. As a result, anhydrous solvent is condensed to enter a recovered solvent tank 8, and after separating the solvent, the gas is heated by a heater 9 after passing through the deoxidation process, then the heated gas is returned to the dryer 1 through the feed pipe 10. In deoxidation process, the uncondensed solvent vapor and noncombustible gas such as nitrogen gas containing a slight amount of oxygen gas are, in the wet deoxidation method, passed through a gas-liquid contact apparatus 15 such as scrubber using deoxidized liquid such as sodium sulfite as the alkaline solution of gallic acid, or in the dry deoxidation method, passed through a granulating layer 17 of activated iron to change activated iron into FeO, FeO 2 . Thus, deoxidation is achieved.

The substrate 2 and the second cores 3 of N pieces form N pieces of head cores having a gap (g), a magnetic flux corresponding to a signal magnetic field is led into the core, and the magnetic flux passes through the Hall effect element film and is shunted. That is to say, a magnetic flux density is applied vertically to the Hall effect element film, and signal voltage corresponding to N pieces of tracks is generated in the terminals ai, bi. In case of recording, a high frequency voltage for bias is applied between the terminals (d), d', and a bias magnetic field is generated in the gap (g). The signal magnetic field applies a signal current to a winding 5 formed on N pieces of core parts. In this regard, a reproducing output is in proportion to a Hall coefficient, a bias current and a magnetic flux density, in inverse proportion to a film thickness, and does not contain the secondary higher harmonic distortion.
