Durable hydrophilic compositions comprising aliphatic polyester, an anionic surfactant, and in some embodiments, a carrier.

An opening/closing apparatus is provided for use in a molding apparatus, such as an injection molding machine. The opening/closing apparatus may eliminate the influence of a slight gap formed between a bush and a pin in a link connecting portion of a toggle link mechanism and in addition, can enhance workability e.g., in mold replacement. An opening/closing apparatus of the present technology may include an opening/closing mechanism including a toggle link mechanism connecting a pressure-receiving platen and a movable platen; a drive mechanism for driving the opening/closing mechanism; and a core-back hydraulic cylinder for applying a load to the movable platen in a given direction in conjunction with the first drive mechanism, configured to perform the operation of slightly opening of the mold.

A solar collector is provided. The collector comprises a monolithic flow control component to direct a flow of the heat transfer fluid between an inlet and outlet; and a solar absorber supported by the monolithic flow control component. The monolithic flow control component is able to support the solar absorber without any additional structural components to lend mechanical strength to the monolithic flow control component.

A method of producing a polyethylene resin expanded molded product includes filling a mold with expanded polyethylene resin particles, wherein an internal pressure of 0.12 to 0.16 MPa is applied to the expanded polyethylene resin particles in the mold, and forming the polyethylene resin expanded molded product by heating the expanded polyethylene resin particles and fusing the expanded polyethylene resin particles. The expanded polyethylene resin particles includes 100 parts by weight of a polyethylene resin, 0.08 to 0.25 parts by weight of a cell nucleating agent, 0.3 to 0.8 parts by weight of a polyhydric alcohol fatty acid ester, and 0.01 to 10 parts by weight of a hydrophilic compound, each of the expanded polyethylene resin particles having a weight of 2.5 to 3.5 mg. The polyethylene resin expanded molded product has a density of 0.017 to 0.021 g/cm.sup.3 and a thickness of 10 to 40 mm.

The invention provides a solid foam wound dressing useful for hemorrhage control and wound repair, as well as methods for making such a wound dressing.

Disclosed are an artificial breast implant in which the surface thereof is formed or modified with a silicone open cell (open pore) foam layer, and a method for producing the same. More specifically, disclosed are an artificial breast implant that has a surface including an open cell foam layer made of silicone and thus minimizes side effects such as in vivo rejection, which may occur after implantation of the implant into the body, in particular, the occurrence of capsular contracture to achieve superior biocompatibility and safety, and a method for producing the same.

A pad main body is bonded integrally with an inner pad while covering the front side of the inner pad. A back-side reinforced fabric located on the back side of the pad main body and the inner pad is integrally bonded on the back side of the inner pad and the pad main body by impregnation of foamed synthetic resin materials constituting the inner pad and the pad main body. This allows impregnation of the foamed synthetic resin materials in the back-side reinforced fabric located on the back side of the inner pad and the pad main body. This consequently allows providing a high hardness on the back side of the inner pad while ensuring hardness on the back side of the pad main body.

Disclosed herein are single-use integral indicators and methods and systems for employing the same. Such indicators and their uses are directed toward identifying and rendering inoperable single-procedure medical devices after their intendedand onlyuse.
