Abstract
Official abstract text for this publication.
An ATC antenna device provided on a body of a lead car to receive signals from outside. In the ATC antenna device, a pair of ATC antenna coils is disposed symmetrically with respect to a center line of the body as viewed in a traveling direction of the body, and the paired ATC antenna coils are connected in series and are of opposite phase. An ATC antenna support device is attached to the body to support the paired ATC antenna coils, and is disposed asymmetrically with respect to the center line.
First claim
Opening claim text (preview).
The invention claimed is: 1. An Automatic Train Control (ATC) antenna device provided on a body of a lead car to receive signals from outside by electromagnetic coupling, the ATC antenna device comprising: a pair of ATC antenna coils disposed symmetrically with respect to a center line of the body of the lead car as viewed in a traveling direction thereof, the paired ATC antenna coils being connected in series and oppositely phased; and an ATC antenna support device attached to the body of the lead car to support the paired ATC antenna coils, wherein a first end portion of the ATC antenna support device is connected to a first ATC antenna coil of the pair of ATC antenna coils, and a second end portion of the ATC antenna support device is connected to a second antenna coil of the pair of ATC antenna coils such that the ATC antenna support is longitudinally asymmetric with respect to the center line. 2. The ATC antenna device according to claim 1 , wherein the ATC antenna support device supports each of the ATC antenna coils in a same lateral direction when as viewed in the traveling direction of the body. 3. The ATC antenna device according to claim 1 , wherein the ATC antenna support device is formed of a non-magnetic metal material, a reinforced plastic, or a combination thereof. 4. An ATC signal transmission device comprising: the ATC antenna device according to claim 1 ; and a receiver to receive an induction voltage signal output by the ATC antenna device. 5. A car comprising: the ATC antenna device according to claim 1 ; and a body having a bottom to which the ATC antenna device is attached. 6. The ATC antenna device according to claim 1 , wherein the ATC antenna support device includes two vertically extending support bars, top portions of the support bars being fixed to the body of the lead car. 7. The ATC antenna device according to claim 1 , wherein the ATC antenna support device is formed in an asymmetrical shape with respect to the paired ATC antenna coils.
