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.

First claim

The invention claimed is:

1. A method for using a drawing apparatus for drawing an extended form from a grown form produced by growing carbon nanotubes, the drawing apparatus comprising: a support member configured to support a part of the grown form; and a drive unit configured to cause a relative movement of the support member and the grown form to draw the extended form from the grown form,
the method comprising:
moving one of the support member and the grown form closer to another of the support member and the grown form to support the part of the grown form with the support member;
moving the one of the support member and the grown form away from the another of the support member and the grown form to draw the extended form from the grown form, the support member supporting a first position of the drawn extended form, the first position of the drawn extended form corresponding to the part of the grown form; and
after drawing the extended form, while supporting the first position of the drawn extended form with the support member, (1) moving again the one of the support member and the grown form closer to the another of the support member and the grown form, and (2) then supporting at least one of a second position of the drawn extended form or a part of the grown form continuous with the drawn extended form.

2. The method according to claim 1 , further comprising preventing a part of the drawn extended form sticking to another part of the drawn extended form when the one of the support member and the grown form is again moved closer to the another of the support member and the grown form.

3. A method of drawing an extended form from a grown form produced by growing carbon nanotubes, the method comprising:
moving one of a support member and the grown form closer to another of the support member and the grown form to support a part of the grown form with the support member;
moving the one of the support member and the grown form away from the another of the support member and the grown form to draw the extended form from the grown form, the support member supporting a first position of the drawn extended form, the first position of the drawn extended form corresponding to the part of the grown form; and
after drawing the extended form, while supporting the first position of the drawn extended form with the support member, (1) moving again the one of the support member and the grown form closer to the another of the support member and the grown form, and (2) then supporting at least one of a second position of the drawn extended form or a part of the grown form continuous with the drawn extended form.

4. A method of drawing an extended form from a grown form produced by growing carbon nanotubes, the method comprising:
moving one of a first support member and the grown form closer to another of the first support member and the grown form to support a part of the grown form with the first support member;
moving the one of the first support member and the grown form away from the another of the first support member and the grown form to draw the extended form from the grown form, the first support member supporting a first position of the drawn extended form, the first position of the drawn extended form corresponding to the part of the grown form;
after drawing the extended form, while supporting the first position of the drawn extended form with the first support member, supporting with a second support member at least one of a second position of the drawn extended form or a part of the grown form continuous with the drawn extended form; and
moving one of (1) the first and second support members and (2) the grown form away from another of (1) the first and second support members and (2) the grown form to redraw the extended form from the grown form.
