    • A noise processing apparatus measures a first potential difference signal, between a first electrode and a second electrode that is used as a reference electrode, and measures a second potential difference signal, between the second electrode and a third electrode that is arranged on the steering unit in the apparatus. The apparatus calculates the difference between the intensities of the first potential difference signal and the second potential difference signal calculated at the predetermined intervals. The apparatus corrects the first potential difference signal or the second potential difference signal by using the calculated difference such that the intensities of the first potential difference signal and the second potential difference signal are canceled out. The apparatus calculates a differential signal indicating the difference between the first potential difference signal and the second potential difference signal by using the corrected potential difference signal, and outputs the differential signal.
    • 噪声处理装置测量在用作参考电极的第一电极和第二电极之间的第一电位差信号,并测量第二电极和布置在转向单元上的第三电极之间的第二电位差信号 在装置中。 该装置计算第一电位差信号的强度与以预定间隔计算的第二电位差信号之间的差。 该装置通过使用计算出的差值来校正第一电位差信号或第二电位差信号,使得第一电位差信号和第二电位差信号的强度被抵消。 该装置通过使用校正的电位差信号来计算指示第一电位差信号和第二电位差信号之间的差的差分信号,并输出该差分信号。

    • A two-cycle internal combustion engine having an oblong cylinder and an oblong piston therein. The engine includes two sets of scavenging ports at either end of the oblong cylinder having at least three ports each. Scavenging passages extending to the scavenging ports may be directed at sequentially increasing angles of inclination to the local normal with the cylinder away from the exhaust porting. In this way, flow may be directed across the piston head away from the exhaust porting and then upwardly to return toward the exhaust porting. A domed piston is also disclosed having discrete guide surfaces on the domed surface of the piston to specifically direct incoming air/fuel mixture upwardly from each of the scavenging ports. An element of the cylinder midway in the long dimension of the cylinder extends in the direction of piston movement without porting so as to provide a smooth wall surface. An oblong piston ring mounted within a groove in the piston has a break in the ring coincide with the unported cylinder element to reduce stress and friction.
    • 一种双循环内燃机,其中具有长圆筒和长圆形活塞。 发动机包括两组在长圆筒的两端的清扫口,每组具有至少三个端口。 延伸到清扫口的清扫通道可以以与汽缸远离排气口的顺序增加的倾斜角度指向局部法线。 以这种方式,流动可以穿过活塞头远离排气口,然后向上以朝向排气口移动。 还公开了一种圆顶活塞,其在活塞的圆顶表面上具有离散的引导表面,以将进入的空气/燃料混合物从每个扫气端口向上引导。 在气缸的长度方向上的气缸的元件在活塞的运动方向上延伸而不移动以提供平滑的壁表面。 安装在活塞内的槽内的长圆形活塞环具有环形突起,与未运动的气缸元件重合以减少应力和摩擦。
