    • A limiting-current-type hydrocarbon sensor comprising a solid electrolyte formed of a barium-cerium-based oxide, capable of detecting hydrocarbon stably and accurately regardless of whether no oxygen is present or a high concentration of oxygen is present. The cathode on the surface of the solid electrolyte is formed of an alloyed layer including Au and Al. In particular, an alloyed layer including an Al—Au intermediate phase is suited for the alloyed layer of the cathode. The alloyed layer comprises a first layer including an Al—Au intermediate phase and making contact with the surface of the solid electrolyte and a second layer including a metal Al phase and covering the first layer. The Al phase of the alloyed layer blocks oxygen, and the Al—Au intermediate phase smoothens hydrogen association and reduces the resistance of the electrode. The hydrocarbon sensor can thus detect hydrocarbon accurately even when oxygen is included in an atmosphere.
    • 包含由钡 - 铈系氧化物形成的固体电解质的极限电流型烃传感器,无论是否存在氧气或高浓度的氧气都能够稳定且准确地检测碳氢化合物。 固体电解质表面的阴极由包含Au和Al的合金层形成。 特别地,包含Al-Au中间相的合金层适用于阴极的合金化层。 合金层包括包含Al-Au中间相并与固体电解质的表面接触的第一层和包含金属Al相的第二层并覆盖第一层。 合金层的Al相阻挡氧,Al-Au中间相平滑氢缔合并降低电极的电阻。 因此,即使在气氛中包含氧气的话,烃传感器也能够精确地检测烃。

    • A method of manufacturing a stator includes the steps of: (1) forming substantially planar electric wires each of which includes in-slot portions to be received in slots of a stator core and turn portions to be located outside the slots to connect adjacent pairs of the in-slot portions; (2) rolling each of the planar electric wires by more than one turn into a spiral shape; (3) forming a stator coil by assembling the rolled electric wires through elastic deformation thereof; and (4) assembling the stator core and the stator coil to form the stator. Further, in the rolling step, each of the planar electric wires is rolled by plastically deforming the turn portions into circumferentially-extending sections each having a predetermined curvature. Furthermore, a curvature ratio of a radially-outermost one of the circumferentially-extending sections is set to be greater than that of a radially-innermost one of the same.
    • 一种制造定子的方法包括以下步骤:(1)形成基本上平面的电线,每个电线包括被接纳在定子芯的槽中的槽内部分,并且转动部分位于槽的外侧,以连接相邻的 槽内部分; (2)将各个平面电线卷绕成多于一圈的螺旋形状; (3)通过弹性变形组装轧制的电线来形成定子线圈; 和(4)组装定子铁芯和定子线圈以形成定子。 此外,在轧制步骤中,每个平面电线通过将转弯部分塑性变形成各自具有预定曲率的周向延伸部分而卷起。 此外,周向延伸部分中的最外侧的一个的曲率比设定为大于其径向最内侧的曲率比。
