Patent number: 6084191Abstract: In a circuit breaker utilizing a toggle link mechanism, the reset operation is facilitated. A block link including a reset pin, a first hole and a second hole is provided. The reset pin is inserted into a circular arc shape third hole formed concentric with the rotation of a trip lever formed at a secured frame. An actuating pin of a handle lever is inserted into the first hole. A shaft provided at a movable contact holder is inserted into the second hole. By this mechanism, the friction in the reset operation can be reduced to allow the reset operation to be perform by a smaller force. As a result, an auxiliary handle is not required. The handle and electrical operation devices can be reduced in size. Also, the operating handle is prevented from moving to the OFF position when the switching contacts are welded.Type: GrantFiled: July 29, 1999Date of Patent: July 4, 2000Assignees: Terasaki Denki Sangyo Kabushiki Kaisha, Moeller GmbHInventors: Ryuji Kataya, Shozo Kaneko

Patent number: 6054912Abstract: A trip device of a main circuit breaker is provided which causes only a branch circuit breaker to be set into a tripped state when an abnormal current occurs at a load of the branch circuit breaker while keeping a closed state of the main circuit breaker. The trip device of the circuit breaker has a structure including a trip latch mechanism for opening switching contacts, a stationary core, a movable core which is attracted to the stationary core to release the latch mechanism of a trip lever, an operating pin for interrupting movement of the movable core while the movable core is attracted, an operating spring charged with force when the movable core is attracted, and an inertia roller holding the operating pin, kicked when the operating spring discharges the force, and moved to a position which does not interrupt movement of the movable core. Accordingly, this structure allows a selective tripping system to be implemented simply with small size and low cost.Type: GrantFiled: August 10, 1999Date of Patent: April 25, 2000Assignees: Terasaki Denki Sangyo Kabushiki Kaisha, Moeller GmbHInventors: Shozo Kaneko, Takeshi Yura

Patent number: 5479462Abstract: Provided herein is a process for producing methanol which was developed to reduce the emission of carbon dioxide which is responsible for global warming. The process involves the steps of generating steam by the use of nuclear heat of a high-temperature gas-cooled nuclear reactor, decomposing the steam into hydrogen by means of a steam electrolyzer, and synthesizing methanol from this hydrogen and carbon dioxide obtained from a carbon dioxide source. The process also involves the steps of converting carbon dioxide and hydrogen into carbon monoxide and steam by means of a reverse shift reactor, forming hydrogen and carbon monoxide of almost the same composition as the conventional one, and reacting said hydrogen and carbon monoxide into methanol by means of a methanol synthesis column. The process permits the use of an existing methanol production facility.Type: GrantFiled: November 3, 1993Date of Patent: December 26, 1995Assignee: Mitsubishi Jukogyo Kabushiki KaishaInventors: Yasuhiro Yamauchi, Yuuji Tokita, Nobuaki Murakami, Katsuhiko Takita, Yasushi Mori, Kensuki Muraishi, Shozo Kaneko, Satoshi Uchida, Nobuhiro Ukeguchi, Seiichi Shirakawa
