Title: Ink jet recording method
Inventor: NATSUHARA TOSHIYA
IPC: C09D11/38
Filed: 1997-02-21
Abstract: PROBLEM TO BE SOLVED: To always stably control a dot size even in the case of environmental change by altering an ink droplet size to be discharge from a nozzle under the control of volume change amount of a piezoelectric element to execute a multiple gradation recording, and using ink having specific surface tension temperature dependence characteristics. SOLUTION: An ink jet printer controls a driving voltage of a piezoelectric element 313 to alter an ink amount to be ejected from a nozzle 307 and dot size, thereby recording with gradation number such as octa-gradations (including no ink ejection) per dot. As aqueous ink, surface tension change rate ΔS represented by ΔS=(S1 -S3 )/S2 is 0.3 or less when surface tension at 5 deg.C is indicated by S1 and surface tension at 25 deg.C is indicated by S2 and surface tension at 40 deg.C is indicated by S3 , and the tension S2 at 25 deg.C is 20 to 50dyne/cm. The rate ΔS is suppressed to 0.3 or less to eliminate problems of decreases of dot reproducibility at large and small particle sides in low and high temperature environments by easily correcting it in a recorder.

Abstract: PURPOSE:To effectively manufacture a light-weight and strong pulley by, after bending the outer periphery of a metal disc material to form a rim portion, placing the material in dies and swaging the rim portion toward the web portion so as to increase the thickness of the base of the rim portion. CONSTITUTION:In manufacturing, the outer periphery of a metal disc material is bent to form a rim portion 2 on the outer periphery of the material. Then, the material is placed in dies 5 and clamped in a direction a, and the side edge 2' of the rim portion 2 is pressed to be swaged in a direction b, so that the amount of material is transferred to the base 4 to complete preforming. In other words, the swaged amount of material is transferred to the base 4 to reinforce this portion. Thereafter, the rim portion 2 of thus performed article is formed on the outer peripheral surface thereof with rolled V-shaped grooves to complete the pulley. This effectively reduces the necessary thickness of material and increases the strength of the base 4 of the rim portion 2, permitting light-weight design. Further, addition of a single operation of swaging facilitates manufacturing.

Then based on the distortion, a virtual read address is stored. Then the original is read and an interpolation arithmetic operation section 35 obtains and outputs a picture density signal Q(t) corresponding to the virtual read address through interpolation of the density of each storage address. Since data are corrected through interpolation in this way, an accurate picture without distortion is obtained.
