Patent number: 11906493Abstract: Gas sensors are provided. The gas sensors comprise: a substrate; a plurality of electrodes on the substrate; and a polymeric sensing layer on the substrate for adsorbing a gas-phase analyte. The adsorption of the analyte is effective to change a property of the gas sensor that results in a change in an output signal from the gas sensor. The polymeric sensing layer comprises a polymer chosen from substituted or unsubstituted polyarylenes comprising the reaction product of monomers comprising a first monomer comprising an aromatic acetylene group and a second monomer comprising two or more cyclopentadienone groups, or a cured product of the reaction product. The gas sensors and methods of using such sensors find particular applicability in the sensing of gas-phase organic analytes.Type: GrantFiled: June 23, 2020Date of Patent: February 20, 2024Assignee: Rohm and Haas Electronic Materials LLCInventors: Catherine Mulzer, Christopher D.

Publication number: 20110097027Abstract: An outer ring for a wheel bearing is provided. The outer ring is designed to attain optimal structural strength and thus prolong a service life of the bearing by establishing theory foundation for dimensions of a supporting end formed on an outer side of an outer diameter surface of the outer ring and a ring groove in which the snap ring is installed which is formed on an inner side of the outer diameter surface and applying optimal dimensions within an allowable threshold range to the supporting end and the ring groove. In addition, the outer ring is also designed to improve space usability of the outer ring by attaining an installing space of a seal member installed on the bearing through an extending end formed on an outer front end surface of the outer ring and improve an assembling property of a snap ring by making a portion of the outer ring from a ring groove to an inner front end as a step surface whose diameter is less than an overall diameter of the outer ring.Type: ApplicationFiled: October 26, 2009Publication date: April 28, 2011Inventors: Jong Soon Im, Hee Jae Yoon, Hyeon Soo Lim
