Abstract: An air-cleaning filter includes a non-woven fabric for dust collection and a non-woven fabric for deodorization having activated carbon particles combined therewith. By adjusting the particle diameter and content of the activated carbon particles and laminating with a non-woven fabric coated with an absorber for other gases, a dust collecting function and a deodorizing function can be imparted at the same time while also creating a structure with a low differential pressure.

Abstract: A helical antenna having a simple structure and being made of cheap conductor to reduce the manufacturing cost, and a manufacturing method thereof. A helical antenna comprises a dielectric core, a conductive strip, a feeding conductor, and an external circuit. The dielectric core has a substantially cylindrical shape with an outer circumferential surface on which a spiral groove is formed. The conductive strip is deposited on the groove of the dielectric core. The feeding conductor is placed under the dielectric core and provides an electrical connection between the conductive strip and an external circuit. The antenna cover encloses the dielectric core and the feeding conductor.
