摘要： An aluminum alloy valve lifter comprises a valve lifter body made of Al-Si (5-20%) type alloy, having silicon average grain diameter of 2 to 40 micrometers, and consisting of a cylindrical portion and a disc portion; an Fe-C type sprayed coating formed on the peripheral surface of the cylindrical portion, containing 0.1% or more of carbon and having a hardness of 300 Hv or more; a wear-resistant chip fixed on the underside of the disc portion; and an adjusting shim set on the upper side of the disc portion.

摘要： A novel ion exchanger useful for universal ion-exchange purposes and, in particular, for ion exchanger for ion-exchange chromatography is proposed, said novel ion exchanger being obtained by introducing radicals of one or more ion-exchangeable groups into cross-linked glucomannan beads by a chemical treatment thereof. Such ion exchanger beads are superior in the compressive strength and permit a high flow rate of the liquid to be subjected to ion exchange through an exchange column packed with them.

摘要： The separation material for separating and recovering a blood coagulation factor comprises a porous matrix having linked thereon one or more ligands each consisting of a radical exhibiting an affinity for the blood coagulation factor to be recovered, said matrix having a specific surface area of at least 1.5 m.sup.2 per milliliter of the separation material with respect to pores having diameters of at least 0.1 .mu.m and being derived from a porous particulate material having an exclusion limit molecular weight of at least 1.5.times.1.sup.6 as determined with polyethylene glycol. The separation material is prepared by the process steps of subjecting a porous particulate material having an exclusion limit molecular weight of at least 1.5.times.10.sup.6 to activation by 1,1'-carbonyldiimidazolating, tresylating, carbodiimidizing, thiopropylating, epoxidizing, bromocyanizing or formylating using the corresponding activating agent and reacting the so activated porous particulate material with one or more substances which exhibit after being linked as ligand on the porous particulate material, an affinity to the blood coagulation factor to be covered, so as to form a porous matrix having a specific surface area of at least 1.5 m.sup.2 per milliliter of the porous particulate material with respect to pores having diameters of at least 0.1 .mu.m.

摘要： A relatively displacing apparatus including a movable member and a stationary member which has a coating layer disposed adjacent to the movable member, formed by flame spray coating and including at least one selected from the group consisting of hexagonal system boron nitride and ceric oxide. Since the coating layer is easily machined with the movable member, the coating layer comes to have a surface generated by machining with the movable member and the clearance between the movable member and the stationary member is made zero (0) substantially when the movable member and the stationary member displace relatively at a high temperature. Thus, the efficiency of the relatively displacing apparatus has improved. In addition, since the coating layer has a high thermal shock resistance, the durability of the relatively displacing apparatus has improved.
