Inventor: HAYAMA TAKATOSHI
IPC: G01C21/00
Filed: 1994-05-10
Abstract: PURPOSE:To correctly calculate and correct a pulse distance coefficient of a vehicle speed sensor when a running distance of a vehicle is to be detected with the use of three kinds of sensors, i.e., a direction sensor, the vehicle speed sensor and a GPS receiver.

Abstract: PURPOSE:To obtain inexpensively and productively satisfactorily a high- performance sound-deadening mechanism which reduces secondary noise, by forming, in the case of connecting a primary sound deadening chamber and an exhaust chamber by means of a plurality of exhaust passages, a primary muffler from squeezed punching metal with small holes made in the entire surface. CONSTITUTION:Gas permeable sound deadners 13 and 14 are set in a body case 4. An exhaust chamber 15 is constituted together with the body case 4. A primary muffler 16 formed by squeezed punching-metal with small holes made in the entire surface constitutes a primary sound-deadening chamber 20, and the holes serve as exhaust passages 17. Because the punching metal receives greater compression load in the lower part of the primary muffler 16, the holes are almost crushed; therefore, noise is effectively insulated. An exhaust flow passes only through the exhaust passages 17 to be led into the exhaust chamber 15, a gas permeable sound deadner 19 covering the exhaust passages 17 completely. The noise of an electric blower 3 itself is reduced by gas permeable sound deadners 22 and 21.
