Title: Zoom lens
Inventor: MORI NOBUYOSHI
IPC: G02B15/16
Filed: 1990-01-18
Abstract: PURPOSE:To decrease the moving quantity of lenses and to obtain the compact and high variable power zoom lens by determining the focal distance of the 3rd lens group of negative, positive and negative 3-lens constitution so as to satisfy specific conditions with respect to the diagonal length of an image plane and adequately disposing the refracting powers of respective lens groups. CONSTITUTION:The negative 1st lens group, the positive 2nd lens group and the negative 3rd lens group are disposed successively from an object side and a stop is provided behind the 2nd lens group. The stop is integrally moved together with th 2nd lens group at the time of variable power. The lenses move to monotonously decrease all the spacings between the respective lens groups at the time of the variable power from a wide angle end to a telephoto end. The conditions of equation are satisfied when the focal distance of the 3nd lens group is designated as f3 and the half of the diagonal length of the image plane as YM. The variable power effect for the change quantity of the spacing is then large as the refracting powers of the adjacent groups are different codes. In addition, the refracting power of the 3rd lens group is increased and the moving quantity of the 3rd lens group is decreased, by which the compact zoom lens in spite of the high variable power is obtd.

Title: Secondary enriching method for desorbing solution of uranium
Inventor: YAMASHITA HISAO
IPC: B01J47/00
Filed: 1982-01-22
Abstract: PURPOSE:To separate and enrich a desorbing solution effectively and obtain uranium of high purity, by treating the desorbed solution of the uranium prepared by using a carbonate as a desorbing agent with a strongly basic anion exchange resin and chelate resin one after another. CONSTITUTION:Seawater is brought into contact with an adsorbent to adsorb uranium, and the adsorbed uranium is then desorbed with a desorbing solution containing a carbonate as a desorbing agent. The desorbing solution consisting of the carbonate is first passed through a strongly basic anion exchange resin. The uranium in the carbonate solution is present as UO2(CO3)3<4->, and subjected to the anion exchange and adsorbed in the resin. On the other hand, cations in the solution are not adsorbed in the  resin and passed directly therethrough. The resin which is previously converted into the carbonate, and the carbonic acid radicals in the desorbing solution are not reduced. Therefore, the solution after the ion exchange is reusable as a desorbing solution of uranium. A solution of NaCl is passed through the anion exchange resin to elute the adsorbed uranium. The resultant enriched uranium solution containing a very small amount of impurities is subjected to the chelate adsorption to improve the purity on forming a yellow cake from the uranium.
