    摘要： To provide a technique suitable for elevating strength and toughness of a thin low-carbon steel. By performing rapid heating and rapid cooling to a thin low-carbon steel which is an ordinary steel with a thickness of 1.2 mm or less, a steel where a microstructure becomes a duplex grain size structure mixed with crystal grains having different grain diameters, which is not homogeneous, preferably, hard phase structures are contained in addition to the duplex grain size structure is obtained, and a high-strength and high-toughness thin low-carbon steel is obtained. Further, by performing a heat treatment process involving rapid heating and rapid cooling multiple times, a duplex grain size structure of crystal grains with smaller grain diameters or a hard phase structure contained therein is obtained, so that a thin low-carbon steel with higher strength and higher toughness is obtained.

    摘要： A biological signal detection device is capable of accurately and simply measuring biological signals and promotes daily health care. A body abutting-side cushioning member 10 formed of a three-dimensional knitted fabric is substantially circular in plan view. A base cushioning member 20 is also substantially circular in plan view. A square one tends to undergo deformation such as turning-up or folding of its edges around the corners when, for example, a person sits thereon. Such deformation tends to distort detection data. Moreover, the folding and the like give a feeling of something foreign. In contrast, a substantially circular one less undergoes such folding and the like.

    摘要： A neck injury is improved with a structure having a lifting mechanism part only on one side. While a lifting driving part is provided on a side of one side frame, a coupling driving rod is coupled to a rotation center of a drive gear a driving link is disposed on a side of the other side frame, and the driving link is coupled to the coupling driving rod. A driving force in the lifting driving part operates on the side of one side frame having the drive gear, but on the side of the other side frame, the driving link rotates together with the drive gear via the coupling driving rod, so as to perform a lifting or lowering operation. The shape of a virtual square coupling contact points of the driving link, the side connectors, the coupling driving rod, and the drive gear does not collapse, and thus an external input is dispersed.

    摘要： A seat suitable for sports type automobiles with a low hip point. An energy absorbing structure part provided in a cushion frame is constituted of a substantially square frame body including a front beam and a rear beam, and stringers bridged across them and provided separately from side frames. It is structured such that belt anchor attaching members are each provided between a coupling position to a vicinity of a rear portion of upper rails of sliders and a coupling position of the rear beam in the stringers. When an impact force of a predetermined value or higher is applied, the stringers deform to absorb the impact force and trusses are formed after the deformation, thereby enabling to sustain a further impact force which continues to be applied.
