The invention provides a method for fabricating a reinforced polymer electrolyte membrane having greatly enhanced durability against a dry/wet cycle or freeze/defreeze cycle. In a method for fabricating a reinforced polymer electrolyte membrane according to the present invention, (1) a polymer electrolyte precursor is caused to infiltrate into a sheet-like porous reinforcing member, in the absence of a solvent, at a temperature higher than the melting point of the sheet-like porous reinforcing member, or (2) the polymer electrolyte precursor is first caused to infiltrate into the sheet-like porous reinforcing member, in the absence of a solvent, at a first temperature lower than the melting point of the sheet-like porous reinforcing member, and then heat-treated at a second temperature higher than the melting point of the sheet-like porous reinforcing member; thereafter, the polymer electrolyte precursor is transformed into a polymer electrolyte by hydrolyzing the polymer electrolyte precursor.

The present invention provides a light-transmitting electromagnetic wave-shielding material for use in displays or in-vehicle panels each having a polarizing plate or a retardation plate, wherein the light-transmitting electromagnetic wave-shielding material undergoes no generation of light interference fringes and is satisfactory in visibility even through sunglasses, goggles, glare-proof panels or glare-proof window materials having polarizing capability. By using unstretched light-transmitting organic polymer materials low in molecular orientation or small in molecular orientation unevenness as the base substrate of an electromagnetic wave-shielding layer, the light-transmitting electromagnetic wave-shielding material excellent in light interference fringe prevention capability can be obtained.

摘要:
An improved video RAM having two data registers for holding data of each row in a memory cell array 1. A transfer gate circuit transfers alternately data of each row of the memory cell array 1 to the two data registers. On the other hand, since a switching circuit selects data held in the two data registers alternately and provide the same serially. In addition, length of data to be provided can be controlled externally. When a special high speed data reading such as oblique reading is required, timing control of externally applied control signals can be simplified.
