Title: Method for coating viscous material
Inventor: OKA MOTOHIRO
IPC: B05D1/26
Filed: 1987-06-30
Abstract: PURPOSE:To enable simultaneous coating of plural kinds of viscous materials by discharging the viscous materials from plural discharge nozzles onto a continuously traveling base material sheet, coating the materials onto the sheet and leveling off the respective viscous materials on the down stream of the nozzles. CONSTITUTION:The base material about sheet 2 is left off from a feed roll, travels at a specified speed under the plural discharge nozzles 13 and is taken up on a take-up roll. The viscous materials A-C are supplied at a specified flow rate from respective constant rate discharging machines 14A-14C to the respective discharge nozzles 13 and are coated in the form of continuous band-shaped films from the nozzles 13 onto the sheet 2 during the travel of the sheet. The sheet 2 to which the materials A-C are stuck is then passed between a surface smoothing roller 15 and a supporting roller 16 by which the viscous materials are leveled off and smoothed to a uniform thickness. The sheet is thereafter dried by passing a dryer 17. The band-shaped reagent layers 3-5 are thus formed.

Abstract: PROBLEM TO BE SOLVED: To attain accurate D/A conversion, even when a delay time of data outputted from a VRAM to the D/A converter is changed, causing a phase shift in the data which depend on condition changes such as temperature. SOLUTION: An MPU 5 writes data from a memory 4 to a VRAM 1. The data are read by a clock phase control section 6 from the VRAM 1, based on a read clock. The clock phase control section 6 generates plural kinds of clock signals whose phase are shifted sequentially in addition to the read clock, and the clock signals are used to allow the control section 6 to receive data from the VRAM 1, without omission. The clock phase control section 6 generates an optimum phase selection signal for a clock signal for the D/A converter, depending on a shift in the phase of the data, read from the VRAM 1. The MPU 5 receives the phase selection signal for an optimum clock from the block phase control section 6 and returns it to the clock phase control section 6.  The clock phase control section 6 selects a clock signal with an optimum phase relation to the data, based on the selection signal input, and outputs it to the D/A converter 3, as the clock signal for the D/A converter.
