The present invention provides a fibrous product of apatite comprising one or more apatites selected from a group of apatites represented by the general formula:M.sub.10 (ZO.sub.4).sub.6 X.sub.2wherein M represents Ca, Ba, Mg, Sr, Pb, Cd, Fe and the like, ZO.sub.4 represents PO.sub.4, AsO.sub.4, VO.sub.4, CO.sub.3 and the like, and X represents F, Cl, OH and the like. This fibrous product of apatite has many applications such as uses for medical treatment, large scale microorganism cultivating media and others, and particularly it is useful as apatite implant materials having a good compatibility with living organism and superior workability.A fibrous apatite product of this invention may be produced by a method comprising the steps of:(a) preparing a dispersion of apatite by dispersing fine apatite particles uniformly in a solution of binder in water, said apatite being one or more apatites selected from a group of apatites represented by the general formula:M.sub.10 (ZO.sub.4).sub.6 X.sub.2 wherein M represents Ca, Ba, Mg, Sr, Pb, Cd, Fe and the like, ZO.sub.4 represents PO.sub.4, AsO.sub.4, VO.sub.4, CO.sub.3 and the like, and X represents F, Cl, OH and the like;(b) continuously exctruding the thus prepared dispersion through a plurality of spinning orifices in a spinning apparatus while simultaneously stretching the dispersion into a fibrous state with the aid of a high speed air flow to form a stream of fine fibers;(c) heating said fiber stream to evaporate the water in the fibers;(d) blowing said dewatered fiber stream upon a collector means to form a cotton-like product of apatite bonded together by the binder; and(e) if desired, calcining said cotton-like product.

A wafer carrier measuring jig includes a base member having a carrier placement section where three kinematic pins are disposed in correspondence with three V-shaped grooves provided on the bottom surface of a wafer carrier having a pair of slot sections where wafers are accommodated. Sensors are provided for measuring height from a predetermined reference value, slot pitch, and slot horizontality with respect to at least some slots in the two slot sections. The obtained data of the slot horizontality and the slot heights of each slot section is written into ID information storage.

A plate-like object container includes a container body having an object-insertion/withdrawal opening formed in a side face thereof for allowing insertion and withdrawal of a plate-like object and a plurality of positioning recesses arranged inside the container body in a direction of the thickness of the object, with an outer periphery of each object being introduced and held in position at each recess. A hook section is provided on an upper face of the container body, the hook section including at least one pair of hook members and support members for supporting the hook members. Each hook member is formed like a plate extending in substantially parallel with an upper face of the container body, the hook members being disposed apart from each other inwardly of an outer periphery of the upper face of the container body. Each support member supports one of the hook members corresponding thereto at a position upwardly distant from the upper face of the container body in such a manner as to allow displacement of the hook members closer to each other through elasticity of the support member per se or of the container body.

摘要:
A micro-porous membrane of ultra-high-molecular-weight alpha-olefin polymer having a weight-average molecular weight greater than 5.times.10.sup.5, the micro-porous membrane having through holes 0.01 to 1 micrometer in average pore size, with a void ratio from 30 to 90% and being oriented such that the linear draw ratio in one axis is greater than two and the areal draw ratio is greater than ten. The micro-porous membrane is obtained by forming a gel-like object from a solution of an alpha-olefin polymer having a weight-average molecular weight greater than 5.times.10.sup.5, removing at least 10 wt % of the solvent contained in the gel-like object so that the gel-like object contains 10 to 90 wt % of alpa-olefin polymer, orientating the gel-like object at a temperature lower than that which is 10.degree. C. above the melting point of the alpa-olefin polymer, and removing the residual solvent from the orientated product. A film is produced from the orientated product by pressing the orientated product at a temperature lower than that of the melting point of the alpha-olefin polymer.
