Title: Production of liquid crystal display element
Inventor: YAMAMOTO YOSHINORI
IPC: G02F1/1341
Filed: 1996-07-18
Abstract: PROBLEM TO BE SOLVED: To provide a process for producing a liquid crystal display element capable of assuring a prescribed uniform gap over the entire surface of a panel. SOLUTION: At the time of curing sealing materials 13 formed on electrode substrates 11, 12 stuck to each other, partition layers 16 are formed to partition cells from the outer side of the cells and the sealing materials 13 are cured in the environment of a pressure higher than the pressure in the electrode substrates stuck to each other and thereafter, at least a part of the partition layers is removed. Liquid crystals are then injected into the cells. The uniform pressurization of the entire surface of the electrode substrates 11, 12 stuck to each other is made possible by the pressure difference between the inside and outside of the cells generated by providing the cells with the partition layers 16. The sealing resins are cured in this state, by which the liquid crystal display element having the excellent gap uniformity is produced.

Filed: 1988-07-29
Abstract: PURPOSE:To facilitate replacement operation by making an ink cartridge freely detachable with respect to a recording head part while providing an engaging means between the ink cartridge and the recording head part and making it possible to simultaneously detaching the recording head part through the engaging means at the time of replacement. CONSTITUTION:In such a state that an ink cartridge 1 is mounted on a recording head part 2, the recording head part 2 is positioned to be held by stopper members 3B and, further, a lock lever 13 is stretched over the ink cartridge 1 from above to fix and mount the whole to a carriage 3. Since the ink cartridge 1 is mounted to the recording head part 2 so that connection force stronger than the holding force by the stopper members 3B holding the recording head part 2 to the carriage 3 is held, in the case of detachment, the ink cartridge 1 can be easily detached along with the recording head part 2 only by releasing the locked state due to the lock lever 13 and, therefore, after both of them are detached, for example, the ink cartridge 1 or the recording head part 2 can be easily separated.

Abstract: PURPOSE:To shorten the time required for forming a U-groove by etching by providing processes for selectively removing an oxide film from the bottom of the U-groove, for filling the U-groove with a material containing an impurity of the same conductivity as that of the substrate into which the U-groove is formed, and for diffusing the impurity of the same conductivity as that of the substrate from the material filling up the U-groove into the substrate at the bottom section of the U-groove. CONSTITUTION:A U-groove 5 having a depth reaching a P-type substrate is formed by an anisotropic dry etching technique. In order to remove a layer in the U-groove damaged at the time of the etching, oxidation is performed and an oxide film 6 is formed. The oxide film 6 is removed by using an etching liquid of a hydrofluoric acid type. At the time of removing the film 6, a mask oxide film 4 used at the time of forming the U-groove 5 by etching is left under the same condition. Another oxide film 8 is again formed in the U-groove 5 and an opening 10 is formed by only removing the bottom section of the film 8 by an anisotropic oxide film dry etching technique. Then the U-groove 5 is filled up with a borosilicate glass (BSG) film 11 containing boron which is a Ptype impurity. By diffusing the boron from the film 11 into the substrate by performing appropriate heat treatment, a channel stopper layer 7 is selectively formed at the bottom section of the U-groove 5 only. Finally, the surface of the U-groove is flattened.
