Title: Stability controller
Inventor: ONO KOICHIRO
IPC: B60W10/18
Filed: 2003-09-03
Abstract: <P>PROBLEM TO BE SOLVED: To provide a structure, which makes it possible to detect the slip of a contacting part between a wheel and a road surface quickly without delay to ensure the travel stability of a vehicle in a higher order.  <P>SOLUTION: According to the structure, a sensor for measuring an axial weight applied between a static wheel and a rotating wheel is incorporated into a roll bearing unit for supporting each wheel on a suspension system. A reference grip force that is assumed to arise at the contacting part when no slip occurs at the contacting part is calculated on the basis of a running speed and a lateral acceleration. Meanwhile, an actual grip force that is actually arising at the contacting part is calculated also on the basis of a detected signal from the sensor. When a deflection between the actual grip force and the reference grip force is large, control for ensuring travel stability is started. The above structure enables the detection of a slip occurring at the contacting part without being influenced by extension/contraction of springs of the suspension system.  <P>COPYRIGHT: (C)2005,JPO&NCIPI

Title: Exhaust gas flow rate increasing device incorporating exhaust pipe
Inventor: FUKUSHIMA AKIHIRO
IPC: B62M7/02
Filed: 2003-08-12
Abstract: <P>PROBLEM TO BE SOLVED: To solve a problem lowering of a flow rate of exhaust gas scavenged from an engine of an automobile or a motorcycle caused by viscosity resistance between the exhaust gas and a muffler or an inside wall of an exhaust pipe and thereby to cause degradation in scavenging capacity of the engine and incomplete discharge of the exhaust gas from a combustion chamber, resulting in degradation in combustion efficiency.  <P>SOLUTION: A metal plate is folded in a wave form of a series of mountains formed so that their cross-section areas become smaller from an inlet port of the exhaust toward an outlet direction, and is processed into a star-shaped tube. The tube is attached to an inner circumference of an outlet part of the exhaust pipe of the automobile or motorcycle. Since the exhaust gas in the center part of the exhaust pipe is compressed at the center and is discharged with increased flow rate, difference between the inside pressure and the outside pressure of the metal plate generates negative pressure on the outside of the metal plate near an outlet. Therefore, the low flow rate exhaust gas near the inner wall of the exhaust pipe is straightened on the outside of the metal plate and is exhausted in high speed to increase the flow rate of the entire exhaust gas. In this device, the complete combustion of the engine is promoted, so that the torque is increased in a range from a low speed region to a high rotational region.  <P>COPYRIGHT: (C)2005,JPO&NCIPI
