    • The present invention enables the coproduction of methanol and ammonia by using a remarkably smaller amount of raw material, natural gas, as compared with the case of independently producing either of methanol or ammonia. Specifically, the present invention provides a process of coproducing methanol and ammonia by using natural gas, LPG, butane, or naphtha as raw material, having a methanol production process (A) composed of specific steps and an ammonia production process (B) also composed of specific steps, in which (1) directing a gas rich in hydrogen recovered in a hydrogen recoverying step in the methanol production process (A) to a certain step after an air reforming step and before a ammonia synthesis step in the ammonia production process (B) to prepare additional feedstock gas for ammonia synthesis; and also (2) cooling a synthesis gas, formed in a steam reforming step in the methanol production process (A) and separating and removing condensed water from the cooled synthesis gas, mixing the water removed synthesis gas and carbon dioxide obtained by pre-compressing carbon dioxide obtained in a CO2 removing step in the ammonia production process (B), compressing up to the methanol synthesis pressure to be supplied as reactant gas for methanol synthesis to the methanol synthesis step (A-2).
    • 与独立地生产甲醇或氨的情况相比,本发明能够通过使用显着更少量的原料天然气来共同生产甲醇和氨。 具体地说,本发明提供了使用天然气,LPG,丁烷或石脑油作为原料共同生产甲醇和氨的方法,其具有由特定步骤构成的甲醇生产方法(A)和还包含氨生产方法(B) 具体步骤,其中(1)在甲醇生产方法(A)中将在氢气回收步骤中回收的富含氢气的气体引导到空气重整步骤之后的一个步骤,并且在氨生产过程中的氨合成步骤之前 B)制备用于氨合成的另外的原料气体; 以及(2)在甲醇生产方法(A)中在蒸汽重整步骤中形成的合成气冷却并从冷却的合成气中分离和除去冷凝水,将除去水的合成气和通过预压缩获得的二氧化碳混合 在氨生产方法(B)中在二氧化碳去除步骤中获得的二氧化碳,压缩至作为用于甲醇合成的反应气体供应到甲醇合成步骤(A-2)的甲醇合成压力。

    • A steering system for a vehicle including a fixed body secured to the body of the vehicle, a fixed shaft rotatably supported by the fixed bracket, a movable bracket connected for relative axial movement to the fixed bracket, a movable shaft rotatably supported by the movable bracket and connected to the shaft so as to be axially movable relative to the fixed shaft and rotatable as one unit with the fixed shaft, a driving mechanism disposed on the fixed bracket and connected to move the movable bracket and the movable shaft axially relative to both the fixed bracket and the fixed shaft, and a control mechanism for controlling the level of the frictional force acting between the fixed bracket and the movable bracket. The control mechanism normally maintains the frictional force at a level to ensure rigidity between the fixed and movable brackets, but is operable, upon actuation of the driving mechanism, to reduce the frictional force and thereby decrease resistance to relative axial movement of the fixed and movable brackets.

    • In a vacuum gate valve, a seal member for sealing a gate opening part is bonded to an outer edge part of a planar seal plate that is disposed in such a manner that the planar seal plate is opposed to a valve seat surface of the gate opening part and comes into contact with the valve seat surface. The seal member includes a vacuum seal part that is located on a side farther from the gate opening part and maintains the sealability of the gate opening part when the gate opening part is closed, and also includes a radical seal part that is located on a side closer to the gate opening part and that prevents the seal member from being affected by a treatment gas in the gate opening part when the gate opening part is closed. The vacuum seal part is made of a rubber elastic body, and the radical seal part is configured by providing a radical resistant body that is provided with an excellent radical resistance on the rubber elastic body.
