Method and apparatus for mixing and supplying fountain solution to printing presses

A process control system especially adapted for mixing and supplying fountain solution to printing press apparatus obviates the need for mechanical float metering devices and scale mechanisms heretofore used for mixing of liquid solution ingredients in prescribed ratios, by providing an electrical circuit control system for measuring the quantity of liquid ingredients to be mixed and for controlling the sequence in which the ingredients are transferred between a plurality of mixing and holding tanks. A selectively variable time base is correlated with the quantity of a primary liquid ingredient introduced to a mixing tank and an electrical sensing device is operative to detect the presence of a quantity of fountain solution within the tank corresponding to a batch thereof. A proportionate relationship is established between the time correlated quantity of the primary ingredient, the quantity of the fountain solution detected by the sensing device, and the quantity of a secondary liquid ingredient introduced to the mixing tank, whereby to precisely preestablish the ratio of the primary ingredient to the secondary ingredient present in each batch of the solution transferred from the mixing tank to a holding reservoir. A series of valves interconnecting the mixing and holding tanks are selectively actuated by the control system to achieve continuous, automatic mixing, and transfer to the holding reservoir of successive batches of the fountain solution, in order to constantly replenish the holding reservoir, as fountain solution supplied to the printing presses from the reservoir is gradually depleted.

TiCl 4 가스와 NH 3 가스를 교대로 복수회 기판에 공급해서 성막을 행함에 있어서, 밸브 장치(1)의 냉각을 억제하면서 N 2 가스의 유량을 크게 하는 것이 가능하고, 스루풋 향상에 기여할 수 있는 기술을 제공한다. TiCl 4 가스와 NH 3 가스를 교대로 복수회 웨이퍼(W)에 공급해서 성막을 행함에 있어서, 한쪽의 처리 가스의 공급과 다른 쪽의 처리 가스의 공급과의 사이에 처리 용기(10) 내에 공급되는 분위기 치환용의 N 2 가스를 사전에 가열하고 있다. 이 때문에, 처리 용기(10)의 내벽이나 웨이퍼(W) 등의 가스 접촉 부위의 냉각을 억제하면서 N 2 가스의 유량을 크게 할 수 있으므로, 분위기의 치환에 필요로 하는 시간을 단축할 수 있고, 스루풋의 향상에 기여할 수 있음과 함께, 밸브 장치(1)의 냉각에 의한 반응 생성물의 부착 등의 문제의 발생이 억제된다. It is possible to increase the flow rate of the N 2 gas while suppressing the cooling of the valve apparatus 1 and to improve the throughput of the N 2 gas when the TiCl 4 gas and the NH 3 gas are alternately supplied to the substrate a plurality of times, Technology. The TiCl 4 gas and the NH 3 gas are alternately supplied to the wafer W a plurality of times so as to be supplied into the processing vessel 10 between the supply of the one processing gas and the supply of the other processing gas The N 2 gas for atmosphere substitution is heated in advance. Therefore, since the flow rate of the N 2 gas can be increased while suppressing the cooling of the inner wall of the processing vessel 10 and the gas contact portion such as the wafer W, the time required for replacing the atmosphere can be shortened, It is possible to contribute to the improvement of the throughput and the occurrence of problems such as adhesion of reaction products due to cooling of the valve apparatus 1 are suppressed.

The flow through each valve (21, 22) is metered so a particular rate of flow can be established. One group of the valves provides dye to the dyeing apparatus while another group of the valves (21, 22) recirculates dye to establish another color ready to be provided to the dyeing apparatus. The colors are defined in terms of the tanks (11-16) and rate of flow from the tanks, so a large group of colors can be defined and stored in a computer, and the computer can control valve position and pump speed to control the color produced by the dyeing apparatus.
