Inventor: TABEI SEIKICHI
IPC: C01B25/00
Filed: 1986-11-25
Abstract: PURPOSE:To obtain stabilized red phosphorus having excellent heat- decomposition resistance, hydrolysis resistance, etc., and suitable as a flame retardant for synthetic resins, by depositing a hydrated compound oxide of titanium-cobalt on the surface of a red phosphorus particle, thereby covering the surface with the oxide film. CONSTITUTION:An aqueous solution of a mixed salt consisting of a titanium salt (e.g. titanic sulfate) and a cobalt salt (e.g. cobalt sulfate) is prepared beforehand. The weight ratio of titanium to cobalt is preferably 1 to 0.1-0.5. Powder of red phosphorus is added to and dispersed in the mixed salt aqueous solution and the obtained dispersion is neutralized with an alkali agent (e.g. ammonia water, sodium hydroxide, etc.). Fine precipitate of hydrated compound oxide of titanium-cobalt produced by the neutralization process is deposited on the surface of the red phosphorus particle to cover the surface. The objective stabilized red phosphorus can be separated and recovered from the product. The amount of the hydrated compound oxide of titanium-cobalt is preferably 0.5-10wt% in terms of Ti+Co based on the red phosphorus particle.

Then, a guard ring 2 is formed on the surface of the epitaxial layer 3 which comes into contact with the polycrystalline epitaxial layers 1 by thermal diffusion in an atmosphere of N2. Then, Pt is coated on the surface of the epitaxial layer 3 surrounded by the guard ring 2; this assembly is sintered in the atmosphere of N2 and a PtSi layer 4 is formed. In this way, a Schottky diode is formed by a junction of the n<-> epitaxial layer 3 and the PtSi layer 4.

Abstract: PURPOSE: To attain the decompression of a compressed color picture. CONSTITUTION: Compressed picture data and encoded data inputted to a picture buffer 10 are transmitted to a decoder 12, and decoded into an address. Then, stored data are read from a ROM 14 by using the decoded address.

Various combinations of colors K1 and K2 are generated by shift circuits 26 and 26', adder logic circuits 23, and MUX 20. The MUX 18 selects either colors K1, K2, and K3 or the combination of the colors K1 and K2 indicating the decompressed data. The output of the MUX 18 is stored in RAM 22. An encoding type is inputted through a control line 27 to a counter 24, and a proper address to be read from the RAM 22 is generated.  Finally, decompressed data are transmitted to a printing engine.
