    摘要： Driving torque outputted from a motor portion is transmitted to a worm from a motor shaft, further to a helical gear from the worm, and is taken out to the outside from an output shaft which rotates together with the helical gear with a fixed shaft fixed to a gear box as a center. This fixed shaft is constructed in a hollow and cylindrical shape having an opening in which one end portion thereof has been opened, and a ceiling surface in which the other end portion thereof has been closed, and one end portion of this fixed shaft is subjected to dislocation preventive work, and is fixed to a gear box made of resin by pressing-in or insert molding. The other end portion of the fixed shaft is formed with the dislocation preventive structure of the output shaft and the helical gear installed to the fixed shaft.

    摘要： A coil assembly for reducing variations in characteristic impedance includes a winding section having a first surface and a second surface on the opposite side of the winding section from the first surface, a plurality of first protrusions provided on the first surface, and a plurality of second protrusions provided on the second surface. These protrusions are identical in shape to each other and are arrayed linearly on their respective surfaces so that the first protrusions are offset from the second protrusions. Two conducting wires are wound between neighboring protrusions such that one wire contacts one of the neighboring protrusions, while the other wire contacts the other neighboring protrusion.

    摘要： According to the present invention, each of the cylinders of an engine is provided with a first and a second swirl ports for generating a swirl of intake air in the cylinder. The second swirl port is located at the position downstream of the first swirl port with respect to the direction of swirl generated by the first intake port. The helical air passages of the first and the second intake port have a bottom which opens to the cylinder and an upper wall facing the bottom and an end wall defining the end of the helical air passage. The angle .theta..sub.1 between the upper wall and the end wall of the helical air passage of the first (upstream) intake port is formed smaller than the same (the angle .theta..sub.2) of the helical air passage of the second (downstream) intake port. By forming the angle .theta..sub.1 small, intake air flowing through the first intake port rotates a large amount before it flows into the cylinder and a strong swirl is formed by the intake air from the first intake port. On the other hand, since the angle .theta..sub.2 is relatively large, intake air flowing through the second intake port flows into the cylinder before it rotates sufficiently. Therefore, the intake air from the second intake port flows into the cylinder without interfering with the swirl in the cylinder. Thus, the flow resistance of the second intake port decreases.

    摘要翻译： 根据本发明，发动机的每个气缸设置有用于在气缸中产生进气的涡流的第一和第二涡旋口。 第二旋流口相对于由第一进气口产生的涡流的方向位于第一涡流口的下游位置。 第一和第二进气口的螺旋空气通道具有通向气缸的底部和面向底部的上壁和限定螺旋空气通道的端部的端壁。 第一（上游）进气口的螺旋空气通道的上壁和端壁之间的角度θ1形成为小于第二（下游）进气口的螺旋空气通道的角度θ1 。 通过形成角度θ1，流过第一进气口的进气在其流入气缸之前大量旋转，并且来自第一进气口的进气形成强烈的涡流。 另一方面，由于角度θ2相对较大，流过第二进气口的进气在其充分旋转之前流入气缸。 因此，来自第二进气口的吸入空气流入气缸而不影响汽缸内的涡流。 因此，第二进气口的流动阻力减小。

    摘要： A combustion chamber of an internal combustion engine is disclosed. The combustion chamber comprises an approximately triangular upper wall in at least one vertical section passing through the center of the combustion chamber, a squish area formed by a peripheral portion of upper wall of piston and the upper wall of the combustion chamber, and a step which is formed on at least one of the peripheral portions of the piston and the upper wall of the combustion chamber. The radial and outward flows impinge on the step inside of the squish area. A height of the step in at least the vicinity of the vertical section is approximately equal to the smallest clearance of the squish area.
