摘要： An earphone antenna is provided that can eliminate high-frequency adverse effects on a wireless device transmitted from a human body via an earphone. The earphone antenna can ensure receiver sensitivity required for a signal in a wide frequency range without any sensitivity control operation and can transmit audio signals from a television receiver to an earphone unit. Two pairs of audio/high-frequency signal lines (8La), (8Lb), (8Ra), and (8Rb) corresponding to the left and right earphone units (12L) and (12R) are connected to a balun (4). Terminals of the two pairs of audio/high-frequency signal lines remote from the balun are connected to the left and right earphone units (12L) and (12R) via loading coils (LLa), (LLb), (LRa), and (LRb). The Terminals of the two pairs of audio/high-frequency signal lines remote from the balun are further connected to each other by a pair of conductive lines (20a) and (20b). The loading coils (LLa), (LLb), (LRa), and (LRb) have low impedance for a fundamental frequency and have high impedance for blocking a specific frequency higher than the fundamental frequency. In addition, the two pairs of audio/high-frequency signal lines (8La), (8Lb), (8Ra), and (8Rb) are used as transmission means for transmitting audio signals to the left and right earphone units (12L) and (12R).

摘要： An exhaust manifold muffler having an exhaust manifold portion 10 and a muffler portion 20 integral with the exhaust manifold portion 10. The exhaust manifold portion 10 includes a plurality of manifold pipes 11 having parallel downstream ends which are spaced from each other and are arranged in a row. Each manifold pipe is connected to a respective cylinder of an internal combustion engine such that exhaust presssure pulsations from the manifold pipes operate as reflected waves opposite in phase, so as to damp the pressure pulsations. The muffler portion 20 has a first muffler chamber 22 and a swirl pipe 29 installed in the first muffler chamber 22. The manifold pipes 11 extend tangentially into the first manifold chamber to produce a swirl in the first muffler chamber 22. Part of the swirl enters an upper inlet end of the swirl pipe. The swirl pipe 29 has a lower outlet end which is located between the downstream ends of the manifold pipes 11. When the recirculated exhaust gas flows out of the swirl pipe 29, it aspirates the exhaust gas from the manifold pipes 11. As a result, the flow resistance of the muffler is small.

摘要： In a construction of a door in a motor vehicle, at a position below a triangular portion located at the forward or rear end of the door where belt lines of a main body of the door and a door window frame intersect at an acute angle, flanges are projected from top portions of a door inner panel and a door outer panel outwardly and inwardly in the thickness-wise direction of the door, respectively, and these flanges are welded to each other. These flanges are formed as a pair of triangular flanges projecting from the door inner panel and the door outer panel with vertexes of the triangular flanges opposed to each other, and the triangular flanges are overlapped at least at portions close to the vertexes thereof and welded to each other at the portions thus overlapped.
