Abstract: A drug-releasable medical device contains a controlled drug-release composition comprising 100 parts by weight of an organic polymeric material which is soluble in an organic solvent and insoluble in water, 5 to 60 parts by weight of a lipid-soluble, low molecular weight release auxiliary agent and 1 to 70 parts by weight of a drug. When the composition is applied on a stent, a catheter, an organ replacement medical device, an artificial organ or the like in the form of coating or the like, the medical device is provided with a drug release function. Argatroban or sarpogrelate hydrochloride or both of them are gradually released from the surface of a stent for treating coronary artery stenosis, for example. In order to exhibit a sustained-release function for a desired period of time, the drug to be gradually released is carried in a polymeric material coated on a surface of a metal forming the stent or in a porous stent substrate.

Each register includes an input port selector for selecting one of the write ports through which data is received. The register file also includes a read data selector block for specifying which data stored in the registers is to be read through one of the output ports. The output port selector is implemented by a combinational circuit which saves power dissipation of the register file.

Abstract: In supplying domestic treated water into which domestic wastewater is treated to demanders of the domestic treated water by transporting the domestic treated water as ballast water of a vessel, a match is made between information on domestic treated water to be supplied and information on demanded domestic treated water. The matching result is sent to ship owners of vessels that transport the domestic treated water. Each ship owner decides and offers a sale price and a transport water quantity to demanders. If a transaction is determined, the information on the domestic treated water to be supplied and the information on the demanded domestic treated water are corrected on the basis of the transport water quantity to make a match again. Thus embodied is a method of supporting a transaction of domestic treated water.

Abstract: In a filtering and purifying system, bacteria in raw water are sterilized efficiently with ultraviolet rays, chemicals and the like at a pretreating step. The number of microorganisms such as bacteria remaining in the treated water is reduced remarkably, and the residue of plankton and organic substances as nutrients for bacteria in treated water is reduced by a coagulating and filtering treatment. It is thus possible to solve a problem that the treated water is deteriorated with time due to propagation of the bacteria.
