Abstract: An inexpensive non-contact communication type information carrier with good handling capability and productivity, characterized in that an IC chip 1 formed integral with the antenna coil 3 is mounted in a recessed portion 6 of a core piece body 5 to form a core piece 11 and that the core piece 11 is mounted at a predetermined position on the information carrier.

Abstract: Deodorizing method and apparatus are disclosed herein which are characterized in that an offensive odor gas is blown or sucked into a deodorizing-swirling section consisting of a swirl-forming plate equipped with fixed wings which is provided in a hollow cylindrical body and a swirl-receiving member provided adjacent to the swirl-forming plate to be rotated in a swirl-like manner at a high speed so that a negative pressure is produced at the central portion of the swirl-forming plate; a deodorizing liquid is sucked and supplied into the deodorizing-swirling section by the negative pressure thus produced to cause the deodorizing liquid to be brought into mixing-contact with the offensive odor gas, while the deodorizing liquid and the offensive odor gas are being rotated in a swirl-like manner at a high speed, whereby the offensive odor gas is deodorized and the clean gas thus deodorized is discharged outside.
