Title: Preparation of synthetic rutile
Inventor: YOSHIKOSHI HIDEYUKI
IPC: C01G23/047
Filed: 1985-03-15
Abstract: PURPOSE:To utilize supplied sulfuric acid completely and to recover ferrous sulfate completely in the prepn. of synthetic rutile by the leaching method using sulfuric acid by adding sulfuric acid to the leaching liquid and cooling the liquid. CONSTITUTION:Titanium one after oxidation and reduction is leached with leaching liquid contg. H2SO4. Obtd. Ti-contg. material having high quality is separated and dried, and then calcined to obtain synthetic rutile. In this process, the temp. of leaching liquid contg. solid components is adjusted to ca.30-80 deg.C where the solubility for ferrous sulfate is high, thus, ferrous sulfate (monohydrate) deposited in the leaching liquid is dissolved. Then, the solid matter in the leached liquid having adjusted temp. is separated and removed (including fine particle separation). Then, H2SO4 corresponding to the equivalent amt. of the reaction for leaching is added to the leaching liquid and cooled, thus, ferrous sulfate in the leaching liquid is separated by crystallization. Separated crystals of ferrous sulfate are washed with industrial water, and residual liquid of the crystallization is mixed with the washing water or industrial water and utilized again for leaching.

Title: Lateral excitation type gas laser device
Inventor: TAKEMORI SEI
IPC: H01S3/038
Filed: 1983-03-24
Abstract: PURPOSE:To generate a high output with a small-sized device by arranging a plurality of cathodes having ring-like discharge parts in a gas flow. CONSTITUTION:The cathodes 3a, 3b,...3i respectively consist of linear parts 3a1, 3b1,...3i1 and the ring-like discharge parts 3a2, 3b2,...3i2, and glow discharge 6 generates between these ring-like discharge parts and the anode 2. Such a construction produces the effect of no concentration of the glow discharge to the cathode tip 3a0. As a result, said discharge generates uniformly in the ring-like discharge part 3a2, resulting in the increase of discharge current. Besides, since the tip 3a0 is put in contact with the linear part 3a1 smaller than said part for temperature increase, there is the effect that the cooling of said part 3a2 is enhanced.
