摘要： The first subject of this invention is a column packing material comprising: a silica gel having a silanol group; a first chemical modification group which is bound to said silanol group; a silicone polymer for coating the surface of said silica gel; and, a trimethylsilyl group which is bound to the silanol group on said silicone polymer and/or the silanol group on said silica gel. The second subject of this invention is a method for producing a column packing material comprising the following steps (A) to (C): (A) a step for introducing a first chemical modification group into a silanol group on the surface of a silica gel by reacting the silica gel with a silane coupling agent having said first chemical modification group; (B) a step for forming a silicone polymer coating on the surface of said silica gel by polymerizing one or more silicone compounds on the surface of the silica gel after step (A); and, (C) a step for trimethylsilylating a silanol group on said silicone polymer and/or a silanol group on said silica gel using an end-capping agent after step (B).

摘要： A cushion unit includes a shock absorber and a suspension spring. The shock absorber includes an open/close valve and a check valve which are arranged in parallel with each other. To increase the height of a vehicle body, the open/close valve is closed so that a piston pressure chamber is allowed to communicate with a spring bracket pressure chamber via the check valve. This causes a hydraulic fluid in the piston pressure chamber to be supplied into the spring bracket pressure chamber under pressure. Accordingly, a cylinder spring bracket slidably arranged around a cylinder of the shock absorber moves upward due to the pressure increase in the spring bracket pressure chamber. Since a lower end of the suspension spring is held against the cylinder spring bracket, the upward movement of the cylinder spring bracket compresses the suspension spring to increase a reactive force thereof so that the height of the vehicle body is increased due to the increased reactive force of the suspension spring.

摘要翻译： 缓冲单元包括减震器和悬架弹簧。 减震器包括彼此平行布置的打开/关闭阀和止回阀。 为了增加车体的高度，关闭开闭阀，使得活塞压力室经由止回阀与弹簧支架压力室连通。 这使得活塞压力室中的液压流体在压力下被供给到弹簧支架压力室中。 因此，由于弹簧支架压力室的压力增加，可滑动地设置在减震器的气缸周围的气缸弹簧支架向上移动。 由于悬架弹簧的下端被保持在气缸弹簧支架上，气缸弹簧支架的向上运动压缩悬架弹簧以增加其反作用力，使得由于增加的反作用力而增加车体的高度 的悬挂弹簧。
