Disclosed is an end structure (16) for a nasal insert tube (2) ofnasal dosing device (1).

A pipe-end processing tool and a pipe-end processing system for it.

An optical fiber end face processing method, an optical fiber end face formed using the processing method and a processing apparatus used in the optical fiber end face processing method.

A processing part of the optical fiber end face processing method has a small area.

A wire end processing method includes tree steps.

In the terminal processing method, the optical fiber (20) constructed from a glass fiber (21) and a cladding (24) is cut, and the optical fiber (20) is pressed against the terminal processing member.

An end processing method for a high-voltage device.

The trailing end-processing device (10) comprises a turret plate (3a), a film roll rotation roller (11), and a trailing end-contacting plate (12a).

The terminal processing member is adapted to make contact with the cladding located at an end surface of the optical fiber (20) and has a space into which the glass fiber (21) can protrude.

5) End machining flat: use the lathe to make the flat end treatment, the remaining amount after processing is 3-5 mm;
