Title: Fabrication of ink jet print head
Inventor: FUJIMOTO HISAYOSHI
IPC: B41J2/16
Filed: 1991-10-09
Abstract: PURPOSE:To make it possible to subject even a line head to polarization processing after machining by applying positive and negative voltages, respectively, onto a set of electrodes so that the wall between individual ink paths is polarized in predetermined direction thereby polarizing the wall associated with both electrodes in the array direction and preventing application of voltage onto at least one adjacent electrode. CONSTITUTION:Electrodes 1, 2 constitute a set and two electrodes 5, 6, separated by two electrodes 3, 4 from the right side of the electrode set, constititute another electrode set. Similarly, electrodes 9 and 10, 13 and 14, 17 and 18 constitute electrode sets, respectively. Positive voltage is then applied on the left side electrodes 1, 5, 9, 13 of respective electrode sets whereas a negative voltage is applied on the right side electrodes 2, 6, 10, 14, 18. Consequently, the barrier 12 of each electrode set is polarized in the array direction. Since the applying voltage is equal to 2kV/mmX0.1mm=200V for a barrier having thickness of 0.1mm, the barrier can be polarized easily even with a considerably low voltage.

Abstract: PURPOSE:To improve the shading correcting accuracy by obtaining the maximum output value against the exposure value of a line sensor within a range of a linear characteristic area and then obtaining the sensitivity correction value of the line sensor against a subject within said maximum output value to store the correction value as the correction data. CONSTITUTION:The change of the output value of a line sensor 16 is previously measured against increase of the exposure value of the sensor 16. Then a light source 12 is controlled so that the maximum output value of the picture element of the sensor 16 set against the reference paper 10 is equal to the maximum linear reference value of the sensor 16. In case of reading an original, the original is set as a picture reading subject in place of the paper 10 and irradiated by the light of the source 12. The shading correction data which is controlled by the maximum value and stored in a correction memory 20 is used to perform an arithmetic operation via a correcting computing element 22 to the picture data undergone A/D conversion. Thus the picture data is outputted in the form of picture signals.

The refractories to be protected are, for example, vacuum degassing equipment, CAS refining equipment, immersion lance, etc. The fig. illustrates the relation between the change in the liquid phase rate and the adhesion thickness of the slag when the temp. changes by 100 deg.C in the temp. range where the change in the liquid phase rate is largest. The results evidence that the slag adheres thickly to the refractories if the liquid phase rate changes by >=70% in the range of 100 deg.C. The adjustment of the slag compsn. is executed by adding of various kinds of oxides and carbooxides (e.g.: calcite, dolomite) or metals (e.g.: Al) or by decreasing of the amt. of addition.
