Abstract: PURPOSE:To ensure that ink density can be adjusted to any specified level at any time under a simple constitution by providing a density control device which mixes inks of different density stored in two ink containers in a mixing vessel at a specified density. CONSTITUTION:Inks of different density are stored in ink tanks 16A, 16B, that is, the ink of high density being in the ink tank 16A and the ink of low density in the ink tank 16B respectively. The ink tanks 16A, 16B are connected to a mixing vessel 20 through pipes 17A, 17B, vessels 18A, 18B and pipes 19A, 19B respectively. The mixing vessel 20 is connected to pipe 22 through pipe 21.

Abstract: PROBLEM TO BE SOLVED: To provide an optical fiber connector highly efficient at low cost. SOLUTION: This optical fiber comprises a cylindrical ferrule 140 and a base 150. An axial route 145 is extended between both end faces of the ferrule 140 and fitted to the naked end part of an optical fiber. The cross-section of the route 145 is normally circular and the diameter is constant in the whole length. Especially, an insertion funnel 151 to lead a fiber to the route 145 is not included in the ferrule 140 and contained in a base 150 which holds the end part of the ferrule 140.
