Abstract: The resistance against the portion of a band body that is riding over engagement claws at the time of fastening the band body is reduced, so that the band body can be fastened by a small amount of fastening force. This boot band consists of: a band body that is fastened by winding in a ring shape an outer overlapping portion and an inner overlapped portion around a member to be fastened; engagement claws and that are formed on the outer overlapping portion; engagement holes that are formed in the inner overlapped portion and that engage with the engagement claws, so as to maintain the band body in a fastened condition; a lip that is formed by separating, along the fastening direction of the band body, the area of the inner overlapped portion where an engagement hole is formed from that area's surrounding area, and with the fastening-direction end of the lip formed as a free end; and a slit, which the lip penetrates through to the opposite side of the slit.

Abstract: A boot-band is configured to be surely fastened around a member and to be clamped, via a one-step operation, without any portion of the band body buckling during fastening. The boot-band includes a pressure-reduction arrangement that is formed in an outer-layer portion in such a manner that it reduces the pressure applied to engagement pawls of an inner-layer portion when the outer-layer portion climbs over the engagement pawls.

Abstract: In order to receive satellite broadcasting (BS and CS) and terrestrial broadcasting (VHF and UHF), complicated wiring is required in a personal residence for transmitting broadcasting signals to a plurality of TV receivers while new distributors must be additionally set for installing additional TV receivers in a condominium previously provided with distributors limiting the number of settable TV receivers. The inventive millimeter wave communication system forms power supply paths by simply connecting a BS/CS antenna with a millimeter wave transmitter and connecting an electronic apparatus such as a TV receiver with a millimeter wave receiver through connectors or the like while transmitting/receiving broadcasting signals by millimeter wave radio communication without employing wires such as coaxial cables indoors.
