Abstract: The purpose of the present invention is to enable a secure attachment of an antenna element and to facilitate adjustment of the antenna element characteristics. Rearward of a spoiler are formed a plurality of lateral grooves extending in a left-right direction of a vehicle, and a plurality of vertical grooves extending in a front-rear direction of the vehicle. The plurality of lateral grooves and the plurality of vertical grooves form latticed grooves as grooves in the shape of a lattice for installing an antenna element. The antenna element is formed by a conductive wire. One end of the antenna element is connected to an amplifier, and the other end is opened.

Abstract: A machining system comprising a plurality of different kinds of single purpose machining units arranged at plural machining stations located along a transfer path, and a transfer apparatus for transferring plural kinds of workpieces along the transfer path so as to position each of the workpieces at plural machining stations successively for machinings by the plural single purpose machining units. The machining system is provided with a return conveyor or a transfer vehicle for transferring the workpieces along a return path from the end of the transfer path to a workpiece unloading station, and a numerically controlled general purpose machine tool arranged adjacent to the return path. The general purpose machine carries out special machinings which cannot be carried out by the single purpose machining units for machining some workpieces which require such special machinings.
