摘要： An object of the present invention is to make it possible, in order to form the fine powder of the water-absorbent resin into a water-absorbing material having particle diameters favorable for practical use, that a water-absorbing material which has high agglomeration strength and is excellent in the quality performances is obtained at a low cost with good efficiency without causing the problems of the adhesion to such as treatment apparatus. As a means of achieving this object, a process according to the present invention for production of a water-absorbing material is a process for production of a water-absorbing material from a fine powder of a water-absorbent resin wherein the water-absorbing material is a particulate water-absorbing material having particle diameters larger than the fine powder, with the process comprising: a step (a) of adding an aqueous liquid to the fine powder of the water-absorbent resin with such as a high-speed stirring type continuous extrusion mixer 50 so that the overall average water content will be in the range of 20 to 60 weight %, whereby particles of the fine powder are agglomerated to thus obtain a particulate hydrous material 70 of the water-absorbent resin; and a step (b) of applying a mechanical compression force to the particulate hydrous material 70 and, at the same time, knead-pulverizing it, with such as a meat chopper apparatus 30, thereby obtaining particulate agglomerates 40 of the water-absorbing material.

摘要： Construction is achieved wherein the rear section of a steering column 6a can be prevented from displacing upward regardless of the occurrence of a secondary collision, and thus can effectively protect the driver. Capsules 28 are supported by a bracket on the vehicle body side. An installation plate section 14b of a bracket 13 on the housing side is held between a top plate section 29 and bottom plate section 30 of each of the capsules 28 so that the installation plate section 14b can displace in the forward direction during a secondary collision. The top and bottom plate sections 29, 30 extend forward to a position where they can support the installation plate section 14b even when the bracket 13 on the housing side has displaced in the forward direction due to a secondary collision. Alternatively, a suspended arm that functions in the same way is provided on the bracket on the vehicle body side.
