摘要:
A novel optical-isomer separating agent for chromatography is provided which has, as a chiral selector, a macrocyclic amide compound having the ability to function as a chiral shift agent. The optical-isomer separating agent for chromatography is formed by bonding, with a carrier by chemical bonding, a specific ring structure containing an asymmetry recognition site, an amide group as a hydrogen-bond donor site, and a hydrogen-bond acceptor site.

A process for production of a chain metal powder, which comprises the steps of reducing metal ions contained in an aqueous solution, while applying a magnetic filed to the solution, in the presence of both a reducing agent capable of generating a gas during the reduction of metal ions and a foamable water soluble compound, through the generation of a gas, a bubble layer on the surface of the aqueous solution to form a chain metal powder, separating the bubble layer formed on the surface of the aqueous solution from the solution, and collecting the chain metal powder contained in the bubble layer.

A developing apparatus includes a toner carrier for transferring toner to a development position, a layer-thickness regulating member for forming a toner layer having a predetermined thickness on the toner carrier by making contact in a leading edge or a surface of a vicinity of the leading edge with the toner carrier, and a supplier for supplying a one-component toner to the toner carrier. Also combined with the layer-thickness layer is a vibration absorbing device allowing the toner to be applied in a uniform thickness. The vibration absorbing device can also be a sealing member located on the toner carrier. Each sealing member can be two different materials effective to absorb vibration.

A method and device for forming a warp beam of uniform diameter by feedback control of winding tension, in which a signal obtained from local winding tensions, each corresponding to a tension of a yarn at a certain widthwise position, are utilized for adjusting the position and width of a reed so that distribution of the warp on the beam is improved and an intra-beam diameter difference is compensated. One of the signals obtained from the local winding tensions is utilized for adjusting the rotational speed of rollers so that an inter-beam diameter difference is compensated. Thus, a warp beam without intra- or inter-beam diameter difference can always be produced.
