Abstract

Embodiments in accordance with the present invention encompass compositions comprising a long shelf stabilized organopalladium compound of formula (I) as described herein. The composition further contains a photoacid generator, a photosensitizer and one or more olefinic monomers as described herein. The shelflife of the compositions can further be extended by employing a stabilizer, such as for example, a hindered amine. The composition undergoes vinyl addition polymerization when it is exposed to a suitable actinic radiation to form a substantially transparent film or a three dimensional object. More specifically, the compositions of this invention are stable at room temperature for several days to several months and can also be stored at higher temperatures from about 40 °C to 60° C for several days and undergo mass polymerization only when subjected to suitable actinic radiation. The monomers employed therein have a range of optical and mechanical properties, and thus these compositions can be tailored to form films and/or three dimensional objects having various opto-electronic properties. Accordingly, compositions of this invention are useful in various applications, including as coatings, encapsulants, fillers, leveling agents, sealants, adhesives, among others.

Abstract

This needle-scalpel (1) for an endoscope is equipped with a needle treatment unit (30) and a tubular body (stopper part (16)). The stopper part (16) is equipped with a proximal reduced-diameter part (slit (16d)) in which a lumen (16k) is narrowed, a distal reduced-diameter part (circular hole part (16e)) located further toward the distal side than the slit (16d), and an expanded-diameter part (16f). The needle treatment unit (30) has a part to be engaged (connecting pipe (14)) that is formed to have a greater diameter than the surroundings and that is accommodated in the expanded-diameter part (16f). When the connecting pipe (14) is in contact with the proximal reduced-diameter part (peripheral wall of the slit (16d)), the peripheral wall of the slit (16d) restricts the position of the needle treatment unit (30) to a first projecting position. Also, when the connecting pipe (14) is in contact with the peripheral wall of the circular hole part (16e), the distal reduced-diameter part (peripheral wall of the circular hole part (16e)) restricts the position of the needle treatment unit (30) to a second projecting position.

Abstract

A method for producing a sealed structure, the method comprising: a step in which granules or a powder (1) formed of an epoxy resin composition is supplied to an extruder that is provided with a screw (42) and a die (5) which is provided at the tip of the screw (42), so that the granules or powder (1) formed of an epoxy resin composition is heated and melted; a step in which the molten epoxy resin composition is extruded from the die (5), which has a predetermined opening shape, by means of rotation of the screw (42); a step in which the extruded epoxy resin composition (6) is cut to a predetermined length, thereby obtaining a tablet that is formed of the epoxy resin composition, the tablet having a diameter of 40 mm to 100 mm and a length of 50 mm to 300 mm; a step in which the tablet is transferred to a transfer molding machine that is provided with a molding die (30) within which an article to be sealed is arranged; and a step in which the article to be sealed (11, 12) within the molding die is sealed with the epoxy resin composition by a transfer molding method that uses the transfer molding machine, thereby obtaining a sealed structure. With respect to this method for producing a sealed structure, the epoxy resin composition contains an epoxy resin, a curing agent, an inorganic filler, a curing accelerator and a wax that has a melting point of 30°C to 90°C.

Abstract

An indwelling device 1 for causing a stent graft 50 to be detained in an organism lumen, the indwelling device 1 comprising: a sheath 11 in which the stent graft is accommodated; a string-shaped conversion means 14 that maintains at least a portion of the stent graft in the axial direction in a contracted state in a state in which the stent graft is discharged from the sheath, and is capable of converting the portion from the contracted state to an expanded state; and an operating means 20 that is operated in order to cause the stent graft to be detained in the organism lumen. The operating means has a first operating part 20A for discharging the stent graft from the sheath, and a second operating part 20B for releasing restriction of the portion of the stent graft by the conversion means.
