IPC: F16J10/00
Filed: 2005-03-11
Abstract: <P>PROBLEM TO BE SOLVED: To provide a cylinder capable of reducing friction and oil consumption by securing excellent oil retention performance without declining productivity.  <P>SOLUTION: A crosshatch angle formed on a bore face 7 of the cylinder 2 is set within a range of 10±5° over the entire bore face 7.

Compared to the case where the crosshatch angle exceeds 15°, oil retention performance is improved and friction can be reduced. Since the number of grooves per unit length is set ≥20 grooves/mm, and the width of a groove 9 is narrowly set ≤30 μm , oil is continuously retained between a piston ring 4 and the bore face 7 during movement of the piston 7. Therefore, lubricating performance of the piston ring 4 is improved, and seizure can be prevented.  <P>COPYRIGHT: (C)2006,JPO&NCIPI

Title: Brake vibration detecting device
Inventor: TAGUCHI TAKEYASU
IPC: B60T8/00
Filed: 2005-03-25
Abstract: <P>PROBLEM TO BE SOLVED: To provide a brake vibration detecting device not for detecting braking hydraulic pressure, but for detecting brake vibrations by another method.  <P>SOLUTION: Brake vibrations are detected on the basis of whether the wheel speed difference between right and left wheels becomes over a predetermined threshold. That is to say, the brake vibrations are detected on the basis of the detection signals of a wheel speed sensor. In this case, a sensor with a simply structure can be used for the wheel speed sensor. Unlike a conventional case where the brake vibrations are found on the basis of variation of the braking hydraulic pressure, even if a high precision and expensive sensor is not used, the brake vibrations can be detected. Such a wheel speed sensor is generally mounted to the vehicle controlled by ABS control and the like now. Therefore, if other parts are not newly mounted, the sensor can detect the brake vibrations.  <P>COPYRIGHT: (C)2007,JPO&INPIT
