Abstract: PURPOSE:To make it possible to eject ink uniformly always in a specified direction when used, and thereby enable high-speed recording, realize a high-density nozzle arrangement and improve durability by implanting ions from an oblique direction against the normal of a discharge orifice during the ion implantation to modify the quality of an surface where the discharge orifice is formed. CONSTITUTION:The subject ink jet recording head consists of a nozzle tube or a nozzle wall 3, a surface layer 2 formed on the former, and a liquid flow path 26 communicating with a discharge orifice 6. The surface layer 2 is formed by an ion implantation method. In this case, an implanted ion incident direction N2 is so arranged that it is gradient with the normal N1 of the discharge orifice 6. Although an angle theta formed by the N1 and the N2 is not necessary defined strictly, the angulation range is roughly 45 deg.<theta<90 deg.. Since the ion implantation from an oblique direction contributes to the modification of a material quality for the end surface where a discharge orifice is formed, the surface shows an extremely satisfactory cohesion. In addition, it is possible to improve water repellence and hardness as well as donate electroconductivity easily by selecting an ion species to be implanted.

Title: Ink jet printer
Inventor: TOGAWA FUMIO
IPC: B41J2/18
Filed: 1979-09-07
Abstract: PURPOSE:To recover the nonrecording ink droplets without enlarging the ink-recovering zone of a gutter, by a method wherein a switching control means for the on-off control of the electric field between deflecting electrodes is provided, and the ink droplets are not deflected except for during the travel for recording of a printing head. CONSTITUTION:The high-voltage power source 12 for impressing a high voltage between the deflecting electrodes 9 is provided with a switching means 13 for conducting the on-off control. The control through the switching means 13 turns on the power to establish the electric field of a high intensity between the deflecting electrodes 9 during the travel for printing of the printing head 1, while turning off the power to stop the deflecting effect of the electrodes 9 during the period other than that mentioned above. Since the deflecting effect is provided only during the travel for printing of the head 1, all the nonprinting ink droplets are recovered in a predetermined gutter position, allowing a gutter with a narrow ink-recovering zone to suffice. In addition, since the ink droplets do not impinge upon the vertical walls of the gutter, the generation of ink mist and the malicious effect thereof can be prevented.
