摘要： There are provided an inorganic filler, multi-functional filler, an organic compound filler, a modified filler, and a dental coloring filler suitable in use as a filler in a dental composition, compositions having a resin matrix of an organic polymer material, as well as a process for producing the same. Disclosed are an inorganic filler which comprises an inorganic fine particle, wherein the surface of the inorganic fine particle is covered with polysiloxane. Also disclosed is a multi-functional filler which comprises an inorganic fine particle containing an acid reactive element, wherein a cement reactive phase is formed on the surface of the inorganic fine particle, and the cement reactive phase is further covered with polysiloxane. Also disclosed is an organic compound filler which comprises an organic-inorganic polymer particle or an organic polymer particle, wherein the surface of the organic-inorganic polymer particle or an organic polymer particle is covered with an inorganic film. Also, disclosed is a modified filler which comprises an inorganic fine particle, wherein the surface of the inorganic fine particle is covered with polyorganosiloxane. Also disclosed is a dental col ring filler, which comprises an inorganic particle and a coloring particle, wherein the inorganic particle and the coloring particle are unifoy mixed and dispersed, the surfaces of these particles are covered with poly(organo)siloxane. Further disclosed are dental compositions containing above fillers, and processes for producing above fillers.

摘要： A plunger for being inserted in a tubular barrel in an axially movable manner includes a plunger body having a distal end positioned within the barrel and a proximal end positioned outside of the barrel, and a seal member disposed on the distal end of the plunger body. The seal member has a base portion extending from the plunger body towards the distal end of the barrel, and a flange portion radially outwardly extending from the base portion and having a peripheral edge contacting an inner circumference of the barrel so as to define an accommodation space within the barrel. The flange portion is elastically deformed to be brought into an elastically deformed state by means of reaction force from a material accommodated within the accommodation space when the seal member is slid towards the distal end of the barrel by means of pressing force applied onto the plunger body so as to force the material out of the accommodation space, and presses the plunger body back towards the proximal end of the barrel by means of self-restoring force of the flange portion when the pressing force is released from the plunger body.

摘要翻译： 用于以可轴向移动的方式插入管状筒体中的柱塞包括柱塞本体，其具有位于筒体内的远端和位于筒体外部的近端，以及设置在柱塞主体的远端上的密封构件。 密封构件具有从柱塞主体朝向筒的远端延伸的基部，以及从基部径向向外延伸的凸缘部分，并且具有与圆筒的内圆周接触的周边边缘，以便限定容纳空间 在桶内。 当密封构件通过施加到柱塞体上的压力而使密封构件朝向筒体的远端滑动时，凸缘部分通过来自容纳在容置空间内的材料的反作用力弹性变形而变成弹性变形状态 从而迫使材料离开容纳空间，并且当按压力从柱塞体释放时，通过凸缘部分的自恢复力将柱塞体向着筒的近端向后压。
