摘要:
A wire for electric railways comprises a copper alloy which consists essentially, by weight percent, of 0.1 to 1.0% Cr, 0.01 to 0.3% Zr, and 10 ppm or less O, and if required, further contains at least one element selected from the group consisting of 0.01 to 0.1% Si and 0.001 to 0.05% Mg, with the balance being Cu and inevitable impurities. The wire is manufactured by hot working a copper alloy billet having the above composition, immediately quenching the hot worked billet to prepare an element wire, cold working the element wire at least once, and subjecting the cold worked element wire to aging treatment.

In a reflective film display device, a platform has a covered stationary electrode mounted thereon, which holds a plurality of movable cantilevers in substantially a plane, and fixing a wiring board. The platform includes an aligning slit for accurately connecting a conducting line on the wiring board to the stationary electrode and to the movable cantilever that can be elastically bent and a through-hole for aligning the position of the platform with another platform. The cantilever having a tab at its free end is electrically separated from the stationary electrode on the platform and a gap is provided between the free end of the cantilever and the stationary electrode. A plurality of platforms are stacked one upon the other by utilizing the through-holes of the platforms so as to allow the tabs to be arranged to form a grid.

A novel display device suitable as a portable display device is disclosed. The device includes a pair of substrates and a light modulation layer sandwiched between the substrates. A functional gel is adapted to be deformed by an electric field applied between a pair of electrodes interposed between the substrates, thereby regulating the light incident on the light modulation layer. A high contrast, a high reflectance and a high light utilization are achieved without regard to the angle of visibility.
