A circular strengthened rib surrounds the orifice of the short circular cannula.

The cross-sectional shape of the outer tube (10) is that of a smooth circular tube.

As a result, delivery and reception of the circular tube body are performed with the circular tube accurately positioned.

The cloth body coiling mechanism (2) comprises a hollow circular tube (4) and a spring pre-tightening mechanism of the hollow circular tube (4).

The circular tube (5) of the outer drum and a circular supply apparatus (6) constitute a temperature control mechanism of closed circuit circular tube.

The bustle pipe has two sections and which are joined by the folding component.

The deformation element is made from a straight circular pipe that is arranged essentially vertically.

The drying case (22) has a large-diameter long circular tube body section (22A) and a small-diameter long circular tube body section (22B).

  The holder is a single part formed by working the same member to form the outer circular tube surface section and the circular tube fitting section.

The circular tube part of the rotor boss is supported by the shaft.

  A staking tube section (22) formed at the front end of the magnetic circular tube body (4) is staked to the connecting recess (13) side to join the magnetic circular tube body (4) and the nozzle member (3) together.

A cathode (102. 104) is disposed adjacent the internal wall of the circular tube.

  The circular tube section (17a) is fitted in an opening (15a) of a valve housing (15) with a gap σ maintained between the circular tube section (17a) and the valve housing (15).

The terminal plate has the shape of a circle, whose diameter is greater than the inner diameter of the circular tube of the valve seat and is smaller than the outer diameter of the circular tube of the valve seat.

A terminal plate is installed at an end of the circular tube of the valve seat.
