Abstract:
A silencer cover adapts to a heat expansion of a silencer even when, for example, the silencer cover has a large size and is attached to the silencer over an area from the front to the rear. A silencer cover is provided for a silencer connected to a downstream end of an exhaust pipe of an engine. The silencer cover is fixed to a fixing support provided to the silencer. The silencer is heat-expanded with the fixing support part fixed as a base. The fixing support part is provided at a front end portion, in a vehicle front-rear direction, of the silencer. With a tail pipe constituting a rear end portion of the silencer, the rear end portion of the silencer is provided with a slide structure in which the silencer cover is slidably supported.
Abstract:
An exhaust-pipe structure for a saddle-ride type vehicle includes expansion paths each having a capacity appropriate for the output capacity of a corresponding cylinder. A front exhaust pipe and a rear exhaust pipe extend from a front cylinder and a rear cylinder constituting a V-type engine, respectively. A silencer is connected to rear end portions of the front and rear exhaust pipes. As expansion chambers, the silencer is provided with a lower first chamber led from the front cylinder and an upper first chamber led from the rear cylinder. A protruding space protruding from the lower first chamber is formed so that the capacity of the lower first chamber led from the front cylinder is larger than the capacity of the upper first chamber led from the rear cylinder.

Abstract:
An exhaust muffler for improving the timbre of an exhaust sound in a low engine speed region and for increasing an engine output in a high engine speed region. In an exhaust device for an internal combustion engine for discharging an exhaust gas from the internal combustion engine through a multistage expansion type muffler having a plurality of expansion chambers for silencing the sound of the exhaust gas during the passage thereof, the multistage expansion type muffler includes a first tail pipe for communicating between a most downstream one of the expansion chambers and the outside of the muffler and a second tail pipe for communicating between an upstream one of the expansion chambers on the upstream side of the most downstream expansion chamber and the outside of the muffler.
Abstract:
A measurement error correcting method and electronic component characteristic measuring device capable of accurately coping with an electronic component which includes nonsignal line ports and whose electrical characteristics are changed by a jig. The method includes the steps of measuring an electrical characteristic, with correcting-data-acquisition samples mounted on a test jig enabling measuring nonsignal line ports, and the samples mounted on a reference jig in which nonsignal line ports cannot be measured; measuring a through device in which a signal line port and a nonsignal line port are electrically connected to each other, with the through device mounted on the test jig, and the through device mounted on the reference jig; determining a numerical expression for calculating, from results of measurement with the through device mounted on the test jig, an estimated electrical characteristic value obtained with the through device mounted on the reference jig; measuring an arbitrary electronic component, with the electronic component mounted on the test jig; and calculating the estimated electrical characteristic value obtained with the through device mounted on the reference jig.
Abstract:
An electronic-component high-frequency characteristic error correcting method for allowing a calibration work to be performed on a two-terminal impedance component using the same correction-target measuring system as that used in actual measurement. At least three correction data acquisition samples having different high-frequency characteristics are measured by a reference measuring system and an actual measuring system. An equation for associating the value measured by the actual measuring system with the value measured by the reference measuring system using an error correction coefficient of a transmission line is determined. A given electronic component is measured by the actual measuring system. An estimated high-frequency characteristic value of the electronic component obtained when the electronic component is measured by the reference measuring system is calculated using the determined equation.
