Abstract: A resist material comprises a polysiloxane obtained by hydrolysis and condensation with dehydration of one or more alkoxysilanes having an oxirane ring, or of a mixture of the alkoxysilane(s) having an oxirane ring and one or more alkoxysilanes having no oxirane ring, and an acid generator. The resist material may contain one or more of a spectral sensitizer, an organic polymer having a hydroxyl group or an epoxy compound. Resist patterns are formed by coating an organic polymer on a substrate and then the resist material on the film of the organic polymer to form a two layer resist having a bottom layer of the organic polymer and top layer of the resist material, prebaking, imagewise exposing high radiation, postbaking, and developing the resist with alkaline solutions to remove an unexposed portion of the top layer, and dry etching the bottom layer using the relic of the resist material as a mask. the temperature of the post baking is preferably lower than that of the prebaking.

Abstract: A medical pump device is constructed so that a pulsation force is applied to the blood in the vicinity of an artery, which is reconstructed after a bypassing operation has been completed, so as to compensate for a deviation of an actual wave form of a blood flow in the vicinity of the reconstructed artery from a normal wave form thereof. The medical pump device is capable of minimizing the possibility of occurrence of a late obturation in an artery which is reconstructed after a reconstruction operation has been completed, and improving a rate of keeping open the reconstructed artery.
