摘要： The invention has an object to provide a solid chloride absorbent which can efficiently absorb inorganic chlorides such as hydrogen chloride flowing out from a process in which a heavy naphtha and the like are treated and inorganic chloride derived from crude oil, and which is difficult to powder and soften after absorbing the chlorides. The solid chloride absorbent according to the invention comprises zinc oxide, a porous refractory inorganic matter and an inert binder, has a long life, and hardly releases the absorbed chlorides.

摘要： There is provided a ballpoint pen tip in which a shoulder of a bent portion does not touch a paper surface during writing and bleeding caused by deformation of an inner periphery of the bent portion can be prevented, and an ink refill using thereof. The ballpoint pen tip 20 comprises a first tapered surface 22 formed by tapering an outer periphery at a front end of a holder 21, a connecting surface 23 that is formed at a front end side of the first tapered surface 22 and has an outside angle larger than 180° with respect to the first tapered surface 22, a second tapered surface 24 that is formed at a front end side of the connecting surface 23 and has an outside angle smaller than 180° with respect to the connecting surface 23, and a bent portion 25 in which a front end portion of the second tapered surface 24 is bent inwardly so as to hold a writing ball 35 inserted into a ball house 29. A boundary between the first tapered surface 22 and the connecting surface 23 is referred to as a first shoulder portion 26, and a boundary between the second tapered surface 24 and the bent portion 25 a second shoulder portion 27. The second shoulder portion 27 is located inside a virtual tangent line 41 between the first shoulder portion 26 and the writing ball 35.
