Abstract: A drawing apparatus includes a support for supporting a part of the grown form and a drive unit for causing a relative movement of the support and the grown form. The support includes a plurality of support units arranged in a width direction of the grown form orthogonal to a drawing direction of a plurality of extended forms, the plurality of support drawing the plurality of extended forms from the single grown form.

Abstract: A drawing apparatus includes a support for supporting a part of a grown form and a drive unit for causing a relative movement of the support and the grown form to draw an extended form from the grown form. The support performs a double support in which, after a predetermined length of the extended form is drawn, at least one of a predetermined position of the extended form or a part of the grown form continuous with the extended form is again supported.

Abstract: A drawing apparatus, which draws carbon nanotubes from a grown form produced by growing carbon nanotubes, includes a holder for holding a part of the grown form by a holding member and a drive unit for causing a relative movement of the grown form and the holder. The holder includes a winding unit for winding a part of the grown form around the holding member.

Abstract: A drawing apparatus that draws an extended form from a grown form produced by growing carbon nanotubes includes a holder for holding a part of the grown form and a drive unit for causing a relative movement of the grown form and the holder. The holder includes a holding member having a receiver unit for receiving a part of the grown form therein.

Abstract: A support device for supporting a cylindrical member around which is wound an elongated body has: a support shaft for supporting the cylindrical member that is fitted to an external surface of the support shaft from an opening on one end in a longitudinal direction of the cylindrical member; an anchoring plates, built into the support shaft, for anchoring the cylindrical member from an inner circumferential side of the cylindrical member; and an operating means having an operation shaft of a smaller diameter than the support shaft, the operation shaft protruding forward from a distal end of the support shaft in order to operate the anchoring plates. Further, the support device has a protecting member which is attached to the distal end of the support shaft and through which is inserted the operation shaft. The protecting member further has a reduced-diameter section smaller in diameter than the support shaft.

Abstract: The invention has a object to provide a G0 transgenic chimera bird which can efficiently accumulate the useful protein in eggs of a female bird in which the protein is expressed in an oviduct-specific manner and can accumulate even a toxic protein in eggs with no ill effect for birds, and a transgenic bird and a method of producing them. The above object can be attained by providing a G0 transgenic chimera bird and transgenic bird obtained by introducing a replication-defective retrovirus vector coding for a useful protein by an oviduct-specific expression promoter.

Abstract: There are provided a finely dispersed material of a functional compound such as pigment or the like in the state of its inherent average particle diameter and a process for producing a finely dispersed material of a functional compound into a binder resin, in which the compound is dispersed in the state of its inherent average particle diameter not more than 3 microns, in spite of using the functional compound having an apparently large average particle diameter by agglomeration in comparison with the inherent average particle diameter of the compound, wherein when the above compound before dispersion is apparently in the dry state, de-ionized water is added thereto to form a hydrous paste of the compound and then this hydrous paste is contacted with a substance having an ion-exchange function selected depending upon the properties of the impurity ions contained in the above functional compound in a mixed solvent composed of de-ionized water and an organic solvent miscible with water to remove the impurity io
