ジャーナル フリーThe Bank Card with the magnetic stripe which was started to use in a full scale since 1970 has remarkably been increased in number because the card was recognized as the best suited media for the computer systems in terms of its reliability in transactions, security and high operation speed. As the network systems enlarged and the number of applications increased, however, the number of misused cards and of insolvents has also been increased. Since the IC Card has emerged as the next generation media with the excellent security, the technological perspective for the future use should be seeked both on the multi-purpose application and the security sides.抄録全体を表示PDF形式でダウンロード (1297K) -

ジャーナル フリーThis paper describes tat the theoretical analysis and the experimental results of the new drop on demand inkjet system using electric field sensitive fluid as ink. The resistance to flow of this fluid can be altered over a wide range by subjecting the fluid to applied electric fields. The fluid is composed of substantial particles such as silica, oily liquid as a vehicle and some suface active agents. The composition of this fluid is similar to that of printing ink. Therefore, we will expect that the copy quality of this inkjet system is as high as that of lithographic printing. A couple of the electrodes is place inside the printhead and the ink is pressurized with the pump. If a sufficient magnitude voltage is applied between the electrodes, the effective fluid viscosity extremely increases so the fluid cannot flow in the prin-thead. When the applied voltage is removed for a short period, the jet of ink is produced because of decreased fluid viscosity. Experimental results show that the ink droplets can be produced by controlled electric fields.抄録全体を表示PDF形式でダウンロード (1542K) -

ジャーナル フリーIn 1868, Japan ended its long period of seclusion. As the influence of outside civilizations penetrated Japanese society, the time was ripe for the creation of a printing industry using movable type. Kakoku SHIMA was a genius among the early Japanese type-casting technology developers. This paper compares the casting technology brought to Japan from overseas and commonly used by Japanese type developers around 1870 with the type manufactured and developed by Kakoku SHIMA for the special purpose of printing books at Daigaku Toko (Eastern College) ***. It also explains the development process.抄録全体を表示PDF形式でダウンロード (3349K) -
