Filed: 1988-01-29
Abstract: PURPOSE:To reduce consumption power by precharging only a part of bit lines including a bit line selected at least by means of an address signal base on a precharge signal and the address signal. CONSTITUTION:When precharge is started, the precharge signal 41 is inputted to an X decoder 42 at the time of '1' are word lines 9 and 10 go to a non-active state.

Abstract: PURPOSE:To satisfy the thrombus resistance and the surface lubricity concurrently by applying a graft copolymerization to the surface of a high polymer membrane with a water soluble monomer whose graft chain density is a specific value, in a guide wire for metical use covered with a high polymer material. CONSTITUTION:In a guide wire for medical use covered with a high polymer material, a graft copolymerization is applied to the surface of the high polymer material with a water soluble monomer, making the graft chain density into 100 to 200mug/cm<2>. By forming a hydrophilic graft chain on the surface of the high polymer material by the graft copolymerization with the water soluble monomer, so as to form a water preservable high polymer chain layer to hold water movable relatively freely, that is, a diffusion layer, the thrombus resistance and the surface lubricity are exhibited. Since it has a diffusion layer, it plays a role of lubricant so as to have a surface lubiricity, which manifets no mutual operation with blood on the surface of the high polymer material at a high density. Consequently, the adsorption or the sticking of blood components can be prevented.
