Title: Treatment for imparting hydrophilic nature
Inventor: KAZAMA AYAKO
IPC: B41J2/16
Filed: 1996-07-04
Abstract: PROBLEM TO BE SOLVED: To improve the wettability of the surface of an ink supply system member and thereby prevent print quality from deteriorating to ensure higher reliability by treating the surface of the member constituting an ink jet head with a diethanolamine solution after treatment with a mixed solution of sulfuric acid and hydrogen peroxide. SOLUTION: An ink chamber constituent member 14 is treated to make it hydrophilic by dipping it in a liquid obtained by mixing 96% of sulfuric acid with 30% of hydrogen peroxide at ordinary temperature in the volume ratio of 8:1 for 15 minutes. Then the member 14 is taken out of the liquid and is cleaned by ultrasonic wave with pure water and further is dried by blowing moisture off the surface. As a result of this treatment for imparting hydrophilic nature, the plastic surface is destructed and consequently, a carboxylic group and a hydroxyl group are formed as hydrophilic groups thus to improve the wettability of the surface of the ink chamber constituent member 14.  Next, the ink chamber constituent member 14 is treated with a diethanolamine solution diluted to 20% concentration with the pure water to realize the bonding of the carboxyl group and the hydroxyl group on the surface of the member 14 with diethanolamine. Thus the polarity is increased and the wettability is enhanced.

IPC: B23D15/04
Filed: 1986-07-26
Abstract: PURPOSE:To reduce a collapse factor and to enable execution of automation and a precise work at an after-process, by a method wherein, after the portion, intended to be sheared, of a material to be sheared is forcibly cooled before shearing, it is sheared. CONSTITUTION:A truck 7 is run and moved to a position located length two times as long as a cutting length l away from a constant sizing machine 1 in linkage with movement of a steel W conveyed on rollers 6 along rails 5. The portion, intended to be sheared, of the SCM case hardening steel W with a diameter of 32mm cooled to, for example 400 deg.C at a cooling bed, is forcibly cooled for seconds by means of spray water through a nozzle 10. In which case, since the portion, intended to be sheared, of the steel W to be sheared conveyed to a shear 2 is cooled down to 300 deg.C, which is detected by a radiation thermometer 12, the steel can be shearted by means of upper and lower bites 3 and 4 without increasing a collapse factor so much. This method shortens a residence period on a cooling bed, improves productivity, and reduces a collapsion factor, resulting in the possiblity to execute automation and a precise work at a process at a unser's place.
