Abstract: PROBLEM TO BE SOLVED: To shorten data transfer/order transmission result reception waiting time by collectively transferring order information after a user completes the designation of all commodities to be purchased. SOLUTION: The user designates the commodities which are desired to be purchased by an input device 70. The commodity code of the commodity is taken out from a part designating the desire of purchase and order information of the commodity, which is required for purchasing the commodity, is read from a commodity information accumulation device 50 and it is written into a storage device 80 in a client terminal. When the user designates an order, a CPU memory displays plural pieces of order information accumulated in the storage device 80 and urges the input of the order number of the individual commodities. When the commodity is cancelled, order information of the commodity is eliminated from the storage device where it is accumulated till then.  When the CPU memory judges the termination of the input of the order number of the commodities, plural pieces of order information accumulated in the storage device 80 are collected into one order unit and it is compiled in a system for transferring it to the server. Then, it is transferred from a communication controller 90 to the server 30.

IPC: G02F1/1333
Filed: 1991-09-30
Abstract: PURPOSE:To increase adhesion property of a SiOx undercoat film formed on the inner side of a plastic substrate to an ITO electrode substrate by adding boron to a hard coating material. CONSTITUTION:The liquid crystal display element having a plastic substrate consists of a pair of plastic substrates 3 and a liquid crystal 10 between these substrates. On the inner side of the plastic substrate 3, there are successively formed an org. material hard coating film 4, SiOx undercoating film 5 and ITO electrode 6. Boron (B) is added to the material of the hard coating film 4. Namely, boron (B) is added by doping or in a form of functional group so that the boron acts as a getter for the water content. Thus when the SiOx undercoat film 5 and ITO electrode 6 are formed by sputtering vapor deposition, the water adsorbed on the plastic substrate is prevented from desorbing and depositing on the vapor deposition surface. Thereby, adhesion property of the SiOx undercoating film 5 and the ITO electrode 6 to the substrate is increased, which prevents cracking in the SiOx undercoat film 5 and the ITO electrode 6.
