摘要： In an apparatus accommodating a rotor of light alloy and a rotor shaft of steel secured to each other, the rotor shaft consists of a first shaft and a pair of second shafts integrally formed with or rigidly secured to the first shaft. The first shaft has a structure with a thermal coefficient of expansion close to that of the rotor whereas each of the second shafts has a structure with a thermal coefficient of expansion less than that of the first shaft.

摘要： An automobile bodyshell frame structure includes a generally elongated first panel member, and a generally elongated second panel member having opposite side edge portions connected to the first panel member to define a hollow between the first and second panel members. A filler is disposed within a portion of a cross-section of the hollow between the first and second panel members. This filler is provided on an inner surface of one of the first and second panel members and has an average compressive strength equal to or greater than 4 Pa and/or a maximum bending strength equal to or greater than 10 MPa.

摘要： A pair of left and right front frames are formed with brittle sections on proximal portions of the frames, by the provision of the smaller cross-sectional area than other sections of the frame. The brittle sections and their peripheral sections are processed so as to become approximately equal to the other sections of the front frames in axial compressive strength by way of a hardening treatment like quenching. In an early-phase of a collision, the hardened brittle sections will not buckle so as to induce larger initial load. Thereafter, the brittle sections will buckle because of their lower ductility, so that the front frames begin bending deformation to effectively absorb the collision energy.
摘要翻译：通过提供比框架的其它部分更小的横截面积，一对左右前框架在框架的近侧部分上形成有脆性部分。通过诸如淬火的硬化处理，将脆性部分及其周边部分加工成以相对于前框架的其它部分的轴向压缩强度大致相等。在碰撞的早期阶段，硬化的脆性部分不会弯曲，从而引起较大的初始载荷。此后，由于其较低的延展性，脆性部分将会弯曲，使得前框架开始弯曲变形以有效地吸收碰撞能量。

摘要： A method for producing a formed member made of a steel sheet according to the present invention is characterized by preparing a steel sheet material having tensile strength of 500 MPa or less and containing a nitriding element; forming a formed member having a predetermined shape by performing a plastic forming on the steel sheet material; and performing a nitriding treatment on the formed member so that an average hardness in the sheet thickness direction of the resultant steel sheet member is Hv 300 or more by Vickers hardness, and further characterized in that the difference in hardness between the surface part and the inside center part in the thickness direction of the steel sheet member of the formed member is Hv 200 or less by Vickers hardness, thereby it is possible to reliably obtain a formed member having a sufficiently high strength after a nitriding treatment while ensuring a plastic formability of a steel sheet in obtaining a formed member made of a steel sheet member of high strength by performing a nitriding treatment after subjecting a steel sheet material to a plastic forming.

摘要： Material characteristics that a foamed filler material (s) to be filled in a frame cross section (fr) should have are discussed. By using a material complying with the characteristics, the energy absorbability of the frame (fr) is effectively enhanced. In a frame structure (fr) for vehicle bodies in which a filler material is filled in at least part of the cross section of a frame, the filler material is set to a mean compressive strength of not less than 4 MPa and/or a maximum bending strength of not less than 10 MPa. More particularly, the filler material is set to a mean compressive strength of not less than 5 MPa and/or a maximum bending strength of 60 MPa.
