Patent number: 5338418Abstract: A process for the production of hydroxocobalamin that eliminates cyanocobalamin as an intermediate. Co-enzyme-type vitamin B.sub.12 is first absorbed to a divinylbenzene/styrene resin which is washed with warm water and then eluted with a solution containing at least 25% of a lower alcohol. The eluate is then irradiated with a light that causes the conversion of coenzyme-type vitamin B.sub.12 to hydroxocobalamin. Finally, the solution of hydroxocobalamin is treated with alumina or silica which binds the impurities leaving behind the highly purified hydroxocobalamin in the flow-through.Type: GrantFiled: September 14, 1992Date of Patent: August 16, 1994Assignee: Nippon Oil Co., Ltd.Inventors: Takayuki Hirayama, Takashi Kiyota

Patent number: 4565178Abstract: A supercharger control system for an internal combustion engine wherein a control valve is advantageously placed in the inlet bypass of the supercharger. The control valve is activated and controlled by a combination of the throttle position and the pressure differential within the intake manifold. A linkage including a lost-motion mechanism connects the control valve to the engine throttle valve for limiting the closing of the control valve for supercharging to corresponding open positions of the throttle valve. A pressure differential device urges the control valve toward a closed position for supercharging upon the occurrence of a lower pressure at a venturi portion of the air intake than at a portion upstream thereof at the supercharger outlet.Type: GrantFiled: January 24, 1984Date of Patent: January 21, 1986Assignee: Honda Giken Kogyo Kabushiki KaishaInventors: Hidenobu Nagase, Takayuki Hirayama
