Abstract: A compound represented by Chemical Formula (1), and salts thereof are provided. A process for production thereof is also provided. The fluoroethylcamptothecin derivative has high antineoplastic activity, being less toxic, and water-soluble, thus is a useful compound.

Abstract: Proposed is a cured silicone rubber article such as a push button switch covering member having a protective coating layer of a urethane resin-based coating composition having excellent wear resistance against rubbing and capable of giving a dry and rigid touch feeling to the finger tip of the operator of the key tops. The coated silicone rubber article is obtained by subjecting a cured base body of a silicone rubber, prior to the coating with a urethane resin-based coating composition, first to a low temperature plasma treatment and then to a coating treatment with a specific primer composition which is a mixture of an epoxy group-containing organosilane compound and an amino group-containing organosilane compound in a molar mixing ratio in the range from 1:2 to 1:5.

Abstract: The multi-state support provides the use of pressurized fluid to cause expansion of an expandable volume positioned above a roller assembly which, in turn, places the support in either a rolling or non-rolling state. In a first embodiment, the roller assembly is fixed relative to a support surface. Expansion of the volume results in contact between a wall of the expandable volume and the rollers of the roller assembly. This contact prevents rotation of the rollers and defines the non-rolling state. In a second embodiment, the roller assembly is moveable relative to the support surface. Expansion of the volume results in the contact between a wall of the expandable volume and the roller support without interfering with the ability of the rollers to rotate relative to the roller support. Expansion of the volume causes the extension of the rollers of the roller assembly from within the sole. The extension of the rollers from the sole defines the rolling state.
