Title: Method and device for manufacturing liquid crystal display element
Inventor: ONUMA KENJI
IPC: G02F1/1339
Filed: 1992-05-15
Abstract: PURPOSE:To maintain the uniformity of the density distribution of scattered particles even if a spray nozzle for scattering spacers and adhesive beads and a substrate are put at a shorter distance and to increase the size of the substrate by moving the spray nozzle above the substrate. CONSTITUTION:The two-liquid spray nozzle 61 receives volatile dispersed liquid in a container 62 under negative pressure produced by the supply of gaseous N2 and sprays it on the substrate 65. Consequently, the liquid level in the container 62 gradually falls, but a photoelectric sensor 63 detects the liquid level at all times and the liquid level is corrected and controlled by an elevating machine. Consequently, the difference DELTAH=H2-H1 between the height H2 of the tip of the spray nozzle 61 and the height H1 of the liquid level of the dispersed liquid is held constant with precision + or -1/2d. Here, (d) is the interval between a couple of photoelectric sensors 63. Therefore, even when the liquid level in the container 62 falls, the amount of volatile dispersed liquid 60 sucked up by the two-liquid spray nozzle 61 does not decrease and the arrangement density of particulates 66 on the substrate 65 never decreases.

Filed: 1998-05-29
Abstract: PROBLEM TO BE SOLVED: To surely remove a foreign matter contained in air with a small quantity of cleaning water and, at the same time, enhance humidification effects by atomizing a circulating water to an air flow and humidifying the air simultaneously with the capturing of the foreign matter in the air and further spraying cleaning water to the air flow to capture the foreign matter residing in the air. SOLUTION: A circulating water in a storage tank 18 is atomized from a first-stage nozzle 16 to the flow of an air A introduced into a water spray chamber 13 formed in the body casing 12 of an air washer 11 from an air inlet 13a through a first washer medium 14. Thus, a circulating water stored in a storage tank 18 is atomized from a first stage nozzle 16. Further, most of the atomized water is caused to collide with dust or an injurious gas contained in the air A and these materials are combined together to be captured by the first washer medium 14. At the same time, the atomized water is vaporized to moisten the air. In addition, a part of the atomized water loads the dust and the injurious gas contained in the air A into the water itself and moves, when a second washer medium 15 captures the dust and the injurious gas.  After that, the cleaning water is atomized from a second stage nozzle 17 to the air A flow and loads and captures the residual dust and injurious gas.
