    • Of side wall portions (60a, 60b) of a tubular body portion (52) mainly constituting an impact absorbing member (50), a wider side wall portion (60a) on the vehicle inner side is provided with a projecting rib (70) projects outward in the direction perpendicular to the axis of the body portion. The projecting rib (70) extends from an axial end (52a) adjacent to a mounting plate (54) and parallel to the axial direction of the body portion. Therefore, even when an impact load is applied to the impact absorbing member (50) in an oblique direction with respect to the vehicle to generate a moment load, the existence of the projecting rib (70) prevents the impact absorbing member from falling down laterally. Accordingly, excellent impact-absorbing properties are stably obtained. The projecting rib (70) is formed not to reach the load input side, i.e., the axial end (52b) adjacent to a mounting plate (56), where collapse starts. Therefore, no load increase occurs in a crash initial stage to well maintain impact-energy-absorbing properties.
    • 主要构成冲击吸收部件(50)的筒状部(52)的侧壁部(60a,60b),车辆内侧的宽侧壁部(60a)设置有突出肋(70) 向外垂直于主体部分的轴线。 突出肋70从邻近安装板(54)的轴向端部(52a)延伸并且平行于主体部分的轴向方向延伸。 因此,即使当冲击负荷相对于车辆沿倾斜方向施加冲击载荷以产生力矩载荷时,突出肋70的存在防止冲击吸收构件侧向跌落 。 因此,稳定地获得优异的冲击吸收性能。 突出肋(70)形成为不到达负载输入侧,即邻近安装板(56)的轴向端部(52b),其中塌缩开始。 因此,在碰撞初始阶段不会发生负载增加,以保持冲击吸收能力。

    • An exhaust system for a motorcycle includes a muffler configured for attachment at a location substantially beneath a motorcycle engine. The muffler includes a first input port and a second input port. A first exhaust pipe has a first longitudinal length. The first exhaust pipe is configured for extending between and connecting the first input port and a first exhaust port of a first motorcycle engine cylinder while being substantially entirely disposed forwardly of a motorcycle engine. A second exhaust pipe has a second longitudinal length substantially equal to the first longitudinal length. The second exhaust pipe is configured for extending between and connecting the second input port and a second exhaust port of a second motorcycle engine cylinder. A motorcycle including an exhaust system is also provided.

    • A motorcycle includes a main frame having left and right main frame members which each extend obliquely downwardly and rearwardly from a forward end to a rearward end. The forward end of the main frame includes a steering interface and the rearward end of the main frame includes a swingarm interface. An engine is attached to the main frame. A swingarm is attached to the swingarm interface and supports a rear wheel. A seat is attached to the main frame at an attachment location. The main frame, the swingarm, and the seat together at least partially define an open space of sufficient size to facilitate substantially complete access to the second cylinder head when the motorcycle is fully assembled.

    • An amount of change calculated by an amount-of-change calculator (11) is stored in an amount-of-change storage (12), and an amount-of-change comparison unit (13) compares an amount of change between a frame one frame before a frame whose gradation is to be corrected and a frame before that frame. If the amount of change is larger than a predetermined value, correction value data of the frame one frame before is not used, but a correction value table of a frame before the change is chosen and read from a correction value calculator (15). If the amount of change is equal to or smaller than a predetermined value, a correction value table of the frame one frame before which did not changed much is read from the correction value calculator (15) and is written to a lookup table (16). Correction data (level data) is read from the lookup table (16) at an address and is outputted as a gradation-corrected luminance signal. In this way, based on an amount of change in a screen and according to a frame whose gradation is to be corrected, optimum correction data is chosen and gradation correction is performed, and thus optimum gradation correction can be done without a frame memory.
    • 由变化量计算器(11)计算的变化量存储在变化量存储器(12)中,并且变化量比较单元(13)将帧间变化量 在其灰度被校正的帧之前的一帧和该帧之前的帧。 如果变化量大于预定值,则不使用前一帧的校正值数据,而是从校正值计算器(15)中选择并读出改变之前的帧的校正值表。 如果改变量等于或小于预定值,则从校正值计算器(15)读取一帧之前没有变化很大的帧的校正值表,并将其写入查找表(16) 。 从查找表(16)以地址读取校正数据(电平数据),并作为灰度校正亮度信号输出。 以这种方式,基于屏幕的变化量和根据要校正其灰度的帧,选择最佳校正数据并执行灰度校正,因此可以在没有帧存储器的情况下进行最佳灰度校正。
