  • Publication number: 20080238025
    Abstract: Disclosed is an attachment structure of a steering damper for a vehicle. The steering damper is provided between a top bridge and a head pipe. The top bridge rotates about a steering stem in conjunction with the operation of a handlebar, while the head pipe does not rotate in conjunction with the operation of the handlebar. In the attachment structure, in a state where the steering angle of the handlebar is zero, the axis of the steering damper forms an obtuse angle with the axis of a bolt to which an upper portion of the steering damper is attached.

  • Publication number: 20080054590
    Abstract: A steering damper mounting structure of a vehicle includes a head pipe, a front fork, a fork bridge, and a steering damper. The front fork, which suspends a front wheel, is steerably disposed on the head pipe. The fork bridge connects left and right members of the front fork. The steering damper is mounted on the fork bridge and the head pipe. The steering damper dampens a steering directional movement transmitted from a road surface to a handlebar via the front wheel and the front fork. A lower mounting portion on a side of the head pipe is disposed on a side of an axis as a center of pivotal motion of the front fork relative to the fork bridge, more specifically, an upper mounting portion on a side of the top bridge. The resulting configuration reduces the size of a front portion of a vehicle and a steering damper.

  • Publication number: 20070096449
    Abstract: A steering shaft support structure for an all terrain vehicle in which both forces of push and pull applied to an EPS unit are reduced when a load is applied to handlebars. The structure includes a steering shaft rotatably supported by a body frame and handlebars attached to the steering shaft. The EPS unit is also supported by the body frame. Two sets of adjustable joints are interposed between the steering shaft and the EPS unit in such a manner that their axes are shiftable. With this, if a load is applied to the handlebars, the adjustable joint associated with the steering shaft follows the inclination of the steering shaft, so that the connection point (swing point) of the adjustable joint associated with the EPS unit does not shift. This reduces both forces of push and pull applied to the EPS unit.

  • Patent number: 6539324
    Abstract: It is one object of the present invention to eliminate redundant testing steps from an operation for testing the search function of a content addressable memory having a priority encoder. Before testing is conducted, background data that differ from test data are written (step 21). Then, the background data are read (step 22) and are tested (step 23). The address having the lowest priority is designated (step 26). And the test data are written thereto (step 27). Following this, the search operation is performed (step 28) to determine whether test addresses match search addresses (step 29). Then, the address having the second lowest priority is designated (step 26), and the above processing is repeated for all the addresses (step 32).

  • Patent number: 5961653
    Abstract: An integrated chip having a DRAM embedded in logic is tested by an in-situ processor oriented BIST macro. The BIST is provided with two ROMS, one for storing test instructions and a second, which is scannable, that provides sequencing for the test instructions stored in the first ROM, as well as branching and looping capabilities. The BIST macro has, in addition, a redundancy allocation logic section for monitoring failures within the DRAM and for replacing failing word and/or data lines. By stacking the DRAM in 0.5 mb increments up to a 4.0 mb maximum or in 1.0 mb increments up to an 8 mb maximum, all of which are controlled and tested by the BIST macro, a customized chip design with a high level of granularity can be achieved and tailored to specific applications within a larger ASIC.
