Patent number: 10364206Abstract: The purpose of the present invention is to provide a method for producing 2-halogenated benzoic acids, the method imparting high regioselectivity (high selectivity) and having a shorter reaction time than does the conventional reaction. This method for producing 2-halogenated benzoic acids, in order to achieve the above purpose, is characterized in that benzoic acids and a halogenating agent are reacted in the presence of an alkaline compound, making it possible to highly selectively obtain 2-halogenated benzoic acids.Type: GrantFiled: April 11, 2016Date of Patent: July 30, 2019Assignees: SUMITOMO SEIKA CHEMICALS CO., LTD., ZERIA PHARMACEUTICAL CO., LTD.Inventors: Katsumi Takano, Takeshi Fujiwara, Hiroyuki Shiraishi, Nami Matsuo

Patent number: 5710660Abstract: This invention provides an optical amplifier which has low noise characteristics for a wide range of input signal electric power. The optical amplifier has a plurality of cascaded optical amplifying units, a signal level detector, and a pump-source controller. The pump-source controller changes controlling objects from a pump-source corresponding to a first one of the optical amplifying units to a pump-source corresponding to a second one of the optical amplifying units according to a detection level of the signal level detector from a low level to a high level. When the detection level is outside of a control object range, the optical amplifier controls an output from the pump-source to stabilize. When the detection level is within the control object range, the optical amplifier controls an output from a pump-source of each of optical amplifying units according to the detection level.Type: GrantFiled: February 26, 1996Date of Patent: January 20, 1998Assignees: Kokusai Denshin Denwa Co., Ltd., Mitsubishi Denki Kabushiki KaishaInventors: Shu Yamamoto, Hidenori Taga, Noboru Edagawa, Shigeyuki Akiba, Kuniaki Motoshima, Katsumi Takano, Tadayoshi Kitayama
