Title: Production of high-purity metal bismuth
Inventor: ITO TOSHIAKI
IPC: C22B30/06
Filed: 1987-02-19
Abstract: PURPOSE:To produce metal Bi having extremely high purity by dissolving crude Bi2O3 in concd. hydrochloric acid to prepare an aq. Bi2Cl3 soln., evaporating away the moisture, hydrochloric acid component and low boiling matter contained therein by rectification, then subjecting the soln. further to distillation and refining, forming BiOCl by hydrolysis and subjected to same to hydrogen reduction in succession thereto. CONSTITUTION:After the Bi2O3 having about 99.9% purity is dissolved with the concd. hydrochloric acid, the residues contained therein are removed by suction filtration and the BiCl3-contg. soln. is recovered. The soln. is put into a rectification apparatus and is heated to evaporate away the moisture, hydrochloric acid component and low boiling matter contained therein; thereafter, the soln. is distilled at the temp. near the b.p. to produce refined BiCl3. The BiCl3 is dropped into pure water to form BiOCl by the hydrolysis reaction and after the BiOCl is cleaned and dried, the same is subjected to the hydrogen reduction at 700-900 deg.C in gaseous hydrogen flow. The metal Bi which has extremely high purity and is usable as a raw material for various electronic materials is thus stably produced at a high yield of the raw material.

Abstract: PURPOSE:To control the bounce time to a minimum, to stabilize the movement of a needle valve and to extend the linearity of the amount of fuel injection up to the lower pulse zone by a method wherein the time required for a drive current to reach its peak is made larger than the time by which the opening of the fuel injection valve is delayed.

Accordingly, a needle valve 3 is attracted to the end surface of the connector 7 against the force of a spring 9 but the stroke of the needle valve is regulated by a flange section 10 and a spacer 11 of the needle valve 3. In this case, the time Tip required for the drive current to reach its peak Ip from the time when the drive pulse is applied on the fuel injection valve is combined with an Ip current setting value peculiar to the fuel injection valve so that for example, Tip=1.2msec or the valve opening delay time To=1.1msec is obtained and the equation of Tip-To>=0.1msec is established.
