Abstract: PURPOSE:To manufacture an aluminum foil for packaging having excellent water wettability by overlapping blank materials of Al foils into >=2 layers, and working them in a cold state so that each layer of the foil has the prescribed values respectively in thickness and surface ruggedness. CONSTITUTION:Blank materials of Al foils 5, 5 are overlapped with each other, and are passed through work rolls 3, 3 to roll them in a cold state at a >=25% reduction ratio so that the thickness of each foil is 55-200mu and the roughness at least one suface of it is 1.5-3mu in the rolling direction. Then the ruggedness 2 of 1.5-3mu in the rolling direction are formed in the overlapped surfaces of Al foils 1, 1 after rolling. These Al foils 1, 1 are separately taken up into coils by winding rolls 6, 6. Next, when the coiled Al foil is annealed, a vaporized rolling oil diffuses freely in the width direction of the foil 1 while passing through the spaces formed by the ruggednesses 2, then the oil is easily removed from the whole surface of the foil 1 to obtain a sufficient water wettability.

Title: Data highway system
Inventor: MIZUI KENJI
IPC: H04L12/433
Filed: 1981-12-17
Abstract: PURPOSE:To disperse risks by allowing to control independently a data highway in each station. CONSTITUTION:Respective stations S1-Sn have counters counting up approximately synchronously and these counters are endless counters regarding the number of stations connected to a highway as the maximum value. Addresses corresponding to ''1''-''n'' are assigned to respective stations. When all counters in the stations S1-Sn count up ''1'' synchronously, the station S1 starts the transmission of necessary data because the counter value coincides with the local address value. After completing the transmission of data, the station S1 sends a transmission completion signal to stop transmission. After receiving the transmission completion signal, all stations including S1 count up their counters by +1 and all counters are turned to ''2''. Consequently the station S2 starts transmission. In the same manner the succeeding stations execute transmission in sequence.
