IPC: B41J2/06
Filed: 1986-04-02
Abstract: PURPOSE:To enable an ink to be favorably supplied to a tip part of a recording electrode and perform stabler printing, by providing an ink reservoir for supplying the ink to the recording electrode, and providing an ink transfer body vertically penetrating an ink-supplying pipe, in proximity to a part of the inner wall of the ink-suppoying pipe. CONSTITUTION:When an ink level A is lowered, air is taken into an ink- supplying pipe 42 from the lower side of the pipe 42, whereby an ink film is prevented from being formed. When the ink level A is lowered and separated from the lower end of the ink-supplying pipe 42, an ink 40 is attracted onto a contact rod 38 by capillarity. Simultaneously, the ink 40 flows along the surface of the rod 38 under the surface tension thereof. With the ink 40 attracted onto the rod 38, the quantity of the ink 40 in the pipe 40 on the side opposite to the position of the rod 38 is reduced, whereby a passage for air is generated at that part. Therefore, the ink 40 can smoothly flow out from an ink cartridge.

CONSTITUTION:The soln. of the org. metal compd. which forms the crystal when calcined is applied on the cut end face 3 of the optical fiber consisting of the single crystal 1 having a circular columnar shape or polygonal columnar shape and is then dried and calcined to form the film consisting of the same crystal as the single crystal 1 on the cut face 3 of the fiber and to smooth the end face. Further, the applying-calcining stages are iterated to work the end face of the optical fiber to a projecting shape in the method for forming the end face of the single crystal optical fiber. Namely, the as-cut face 5 of the optical fiber 7 is rough but if this surface is treated by this working method, the smooth surface 6 is obtd. The possibility to generate polishing flaws is eliminated in this way and the coupling loss to be generated at the time of an optical coupling to an optical fiber, etc., is lessened.
