IPC: F02C9/28
Filed: 2005-10-18
Abstract: 変動する電力需要を満足させる方法及び合成ガス流の金銭的価値を最大にする方法を開示する。１つ又はそれ以上の合成ガス(１８；２０；２６)は、炭素質材料のガス化により製造し、ピークの電力需要期間の間、電力生産ゾーン（３８）に送って電力を生産し、またピーク外の電力需要期間の間、化学品生産ゾーン（５４）に送って、化学品、例えばメタノールなどを生産する。電力生産ゾーン（３８）及び化学品生産ゾーン（５４）、周期的に且つ実質的に時期をずらして運転するが、そこではピーク外の電力需要期間の間、１基又はそれ以上の燃焼タービンは停止し、合成ガス燃料は化学品生産ゾーンに差し向けられる。この時期をずらした周期的な運転様式は、電力生産ゾーン（３８）が高い熱力学的効率で電気的出力を最大にすることを可能にし、且つ化学品生産ゾーン（５４）が高い化学量論的効率で化学品製造を最大にすることを可能にする。電力と化学品との生産ゾーンを複合することで経済的な可能性が増進する。

Abstract: <P>PROBLEM TO BE SOLVED: To provide an exhaust emission control device for reducing a specific substance discharged together with exhaust gas, by raising the temperature of a catalyst in a short period of time, when starting an internal combustion engine, without causing a pressure loss and upsizing of a physical constitution.  <P>SOLUTION: An orifice part 40 arranged in an exhaust passage 41 controls the cross-sectional area of the exhaust passage 41 and a flow of the exhaust gas in the exhaust passage 41 by adjusting opening of a first valve member 44 and a second valve member 47. When the temperature of a three-way catalyst 32 is low, the orifice part 40 introduces the flow of the exhaust gas to a part on the outer peripheral side of the three-way catalyst 32. Thus, when the temperature of the three-way catalyst 32 is low, the exhaust gas is introduced to a part of the three-way catalyst 32, and the temperature of the three-way catalyst 32 rises in a short period after starting an engine body 13. The orifice part 40 expands the cross-sectional area of the exhaust passage 41 as the temperature of the three-way catalyst 32 rises, and fully opens the exhaust passage 41 when the temperature of the three-way catalyst 32 reaches the active temperature. Thus, the exhaust gas is introduced to the whole of the three-way catalyst 32, and the pressure loss is reduced.  <P>COPYRIGHT: (C)2009,JPO&INPIT

IPC: B41J2/165
Filed: 2008-02-18
Abstract: <P>PROBLEM TO BE SOLVED: To replace a fluid in an injection head at a proper timing.  <P>SOLUTION: A fluid in a container is injected from an injection head, and outside the injection head, a fluid storage is provided. When the fluid is stored in this fluid storage, at least a part of components of the fluid can be exchanged with the air, and thereby the fluid in the fluid storage can be reduced as time advances. Then, when the fluid in the fluid storage is reduced by a predetermined amount, the liquid in the injection head is replaced with that in the container. The fluid storage and the injection head are exposed to nearly the same environment, and the same can be said for the inside fluids. A reduction of the fluid in the fluid storage and a change of properties of the fluid in the injection head, therefore, have a strong correlation with each other. Thus, if the fluid in the injection head is replaced from the fact that the fluid in the fluid storage is reduced by the predetermined amount, the fluid in the injection head can be replaced only when the properties of the fluid are changed.  <P>COPYRIGHT: (C)2009,JPO&INPIT
