Abstract: PURPOSE:To recover U easily and economically as an insoluble precipitate by adding  sulfuric acid and gypsum dihydrate to wet process phosphoric acid, forming hemihydrate gypsum by heating, adding phosphate ore, causing wet decomposition, separating gypsum dihydrate obtd. by hydrating the hemihydrate gypsum, and adding a precipitant to the resulting soln. after the separation. CONSTITUTION:Sulfuric acid is added to wet process phosphoric acid adjusted to <=  about 0.5% F<-> content to prepare a mixed acid contg. <=25wt% H2SO4, and gypsum  dihydrate is added so as to adjust the concn. of the slurry in a hemihydration stage to  5-40wt%. The slurry is kept at a temp. required to convert gypsum dihydrate into hemihydrate gypsum, i.e., about 85-90 deg.C to prepare a slurry contg. hemihydrate gypsum  contg. 10-5,000ppm U. Phosphate ore is added to the slurry contg. the mixed acid and  the hemihydrate gypsum and reacted with the excess sulfuric acid by a wet decomposition reaction, and simultaneously U in the ore is captured by the hemihydrate  gypsum. This gypsum is separated from the phosphoric acid and hydrated by dispersion in water. During the conversion of the hemihydrate gypsum into gypsum dihydrate, the  U is shifted into the liq. phase. By adding a precipitant to the liq. phase, the U is recovered as an insoluble precipitate.

Title: Thermal transfer recorder
Inventor: TSUMURO YOSHITAKA
IPC: B41J11/053
Filed: 1989-06-22
Abstract: PURPOSE:To enable noise of an apparatus to be reduced by a method wherein a platen to be used for a thermal transfer recorder is supported with a bearing having a damping effect. CONSTITUTION:Paper and an ink film are pushed between a thermal head 1 and a platen 2, and printing is performed. The paper and the ink film are fed with a motor 9.

Title: Valve gear for internal-combustion engine
Inventor: GOTOU HIROMITSU
IPC: F01L13/00
Filed: 1982-09-20
Abstract: PURPOSE:To make a suction valve possible to control its opening or closing according to driving conditions, by installing an adjust screw member coupled with a push rod shiftably in a rocker arm through hydraulic pressure so as to cause a lever ratio to be altered. CONSTITUTION:An adjust screw member 20 being coupled with a push rod 44 is shiftably installed in a rocker arm 16 through hydraulic pressure. The hydraulic pressure to be fed to a fluid pressure chamber 52 varies with engine speed so that a lever ratio of the rocker arm 16 varies as well according to the engine speed whereby a clearance L1 is adjusted. Thus, valve opening time for a suction valve can be adjusted to be slow at high speed but speedy at low speed, therefore sufficient suction air is fed to an engine and stable driving is thus performable over the whole driving range.

Title: Method and apparatus for electrostatic spray of liquid
Inventor: ZAFUIRIOSU BUACHIRASU
IPC: B05D1/04
Filed: 1990-06-22
Abstract: PURPOSE: To increase flow rate while maintaining a desirable particle size by combining and installing side by side a pair of atomizing edges and field- intensifying electrodes of a spraying head equipped with a plural number of the said field-intensifying electrodes. CONSTITUTION: Atomizing edges are set in such a manner that they are separated by the distance (a) and that the closest portions on nozzle assemblies (10 and 11) relative to the surfaces of combined electrodes (26 to 28) form the atomizing edges by themselves (12, 13). High voltage is applied to each of nozzle electrodes (22) and low voltage relative to earth is applied to each of cores of the electrodes (26 to 28) so as to generate an electric potential difference between the nozzle electrodes (22) and the electrodes (26 to 28). Liquid reaching the atomizing edges is exposed to an electric field of high strength generated by the applied electric potential difference and becomes a series of liquid particles to be broken up into atomized particles. High supply amount is thus able to be maintained for its median particle size.
