Title: Ink jet printer
Inventor: OGAWA TOSHITAKA
IPC: B41J2/085
Filed: 1985-10-18
Abstract: PURPOSE:To enable the correction of coming and going character inclinations with a simple small constitution, by a method wherein a deflecting electrode is rotated by a specific angle at a folded point and the center of its rotation is made eccentric from the center of the print head moving direction. CONSTITUTION:Because if a printing head 10 moves right to a use paper 6, the return side of a traction part 11 moves inversely, an electrode holder 12 rotates right via a drive pulley 13 and a plate spring 14 and the lower deflecting electrode 4 becomes eccentric by delta from an ink drop 2 by engaging a stopper 15 with a depressed part 16. Therefore, the going right-handed character inclination and the left-handed character inclination due to deflecting electric field are cancelled and the print character becomes vertical. Then, when the printing head comes back, the drive pulley 13 rotates inversely in the same way and its depressed part 16 is engaged with the other stopper 15'. The deflecting electrode 4 becomes inversely eccentric by delta from the ink drop 2 and the coming left-handed character inclination is cancelled. Thus, the going and coming character inclinations can be corrected by a simple constitution.

Title: Alumina zirconia silica molten refractory and evaluation method thereof
Inventor: ARAI TOMONORI
IPC: G01J3/46
Filed: 1998-08-20
Abstract: PROBLEM TO BE SOLVED: To make rapidly measurable furnace material characteristics in a non-destructive manner by comparing the brightness index and/or saturation index of the color of alumina zirconia silica molten refractory with respectively predetermined set ranges. SOLUTION: High correlation is shown between a brightness index and a saturation index calculated on the basis of JIS Z8729 and furnace material characteristics such as leaching properties, bubble characteristics or the like of matrix glass. Within set ranges wherein a brightness index is 87.0 or more and/or a saturation index is 6.00 or more, a leaching index is small and a sample inferior to the leaching properties of matrix glass is not present. Therefore, the refractory satisfying this prescription is one good in the leaching properties of matrix glass and this set range can be adapted as a good quality control method. In the set range, bubble characteristics are also good. Since the furnace material characteristics can be measured accurately and rapidly, quality reliability can be kept high and the antistaining properties of molten glass can be reduced.
