Abstract: [Object] To provide a transducer capable of providing a high degree of freedom in deformation and suppressing a risk of breakage and a method of producing the transducer. [Solving Means] In order to achieve the above-described object, a transducer according to an embodiment of the present technology includes an elastomer. The elastomer extends along a predetermined axis direction, and has both end portions in which at least two electrodes having followability are disposed on both sides around a predetermined axis in the predetermined axis direction, the both end portions being elongated to be folded in a direction perpendicular to the predetermined axis. This makes it possible to provide a high degree of freedom in deformation and to suppress a risk of breakage.

Abstract: A hydrocarbon adsorbent having high hydrocarbon adsorbing properties even after exposed to a high temperature/high humidity reducing atmosphere, includes a FAU type zeolite having in ESR measurement a spin concentration of a least 1.0×10{circumflex over (?)}19 (spins/g) and a ratio of a peak intensity at a magnetic field of at least 260 mT and at most 270 mT to a peak intensity at a magnetic field of at least 300 mT and at most 320 mT of at least 0.25 and at most 0.50 ? and containing bivalent copper. The hydrocarbon adsorbent may be used for a method for adsorbing hydrocarbons to be exposed to a high temperature/high humidity environment, and may be used particularly for a method for adsorbing hydrocarbons in an exhaust gas of an internal combustion engine, such as an automobile exhaust gas.

Abstract: Provided is at least one of an improvement in the thermal stability of a CHA-type zeolite, which is achieved by a method different from that of the related art for improving thermal stability; a method for producing a CHA-type zeolite that improves thermal stability; and such a CHA-type zeolite. Provided is a CHA-type zeolite having a 1H-MAS-NMR spectrum and an IR spectrum in which, preferably, in the 1H-MAS-NMR spectrum, a ratio of an integrated intensity of a maximum peak having a peak top at a chemical shift of 3.0 to 3.5 ppm to an integrated intensity of a maximum peak having a peak top at a chemical shift of 4.0 to 4.5 ppm is greater than 0.12 and 0.5 or less, and, in the IR spectrum, a ratio of a maximum peak height of an absorption peak having a peak top at a wavenumber of 3630 cm?1 or greater and 3650 cm?1 or less to a maximum peak height of an absorption peak having a peak top at a wavenumber of 3590 cm?1 or greater and 3610 cm?1 or less is 0.40 or greater and 1.0 or less.
