20110166255	SEALING MEMBER FOR PIPING COMPONENT HAVING EXCELLENT CHLORINE RESISTANCE, METHOD FOR PRODUCING SEALING MEMBER FOR PIPING COMPONENT HAVING EXCELLENT CHLORINE RESISTANCE, SEALING MEMBER FOR PIPING COMPONENT HAVING EXCELLENT OIL RESISTANCE, AND PIPING COMPONENT HAVING EXCELLENT OIL RESISTANCE - Disclosed is a method for producing a sealing member for piping materials having excellent chlorine resistance, which includes a first step and a second step. The first step is a step wherein first carbon nanofibers produced by vapor deposition are subjected to an oxidation treatment, thereby obtaining second carbon nanofibers each having an oxidized surface. The second step is a step wherein carbon black having an average particle diameter of from 50 nm to 10 μm and the second carbon nanofibers are mixed into an ethylene-propylene rubber and dispersed in the ethylene-propylene rubber by a shearing force.	07-07-2011
20090025548	Spring-return, pneumatic actuator - A spring-return, pneumatic actuator includes a casing having therein a cylinder chamber, a housing chamber and a spring chamber and equipped therein with a piston reciprocating by means of air supplied and discharged from an air supply and exhaust vent on a primary side of the piston, a piston rod joined to the piston, a conversion mechanism for converting a reciprocating motion of the piston into a rotary motion, a spring undergoing a snap action by means of the reciprocating motion of the piston and a communication space chamber formed via a communication part to have a predetermined volume from a secondary side to the spring chamber. The cylinder chamber has the piston and the piston rod built-in, the housing chamber has the conversion mechanism built-in and the spring chamber has the spring built-in.	01-29-2009
