    Abstract: A biosignal measurement apparatus is used by being affixed on a living body. The apparatus includes an affixed part that is a sheet, in which a signal-acquiring section of multiple electrodes and wiring connected to each of the electrodes are formed, and which can be freely expanded, contracted and bent and is adhesive; and a substrate that is connected to the wiring and on which a signal-processing circuit for wirelessly transmitting biosignals obtained through the wiring is mounted.
    The signal-acquiring section is exposed on the surface of the affixed part and the affixed part and the substrate are stacked so that the back surface of the affixed part faces the substrate.

    Abstract: A heart failure diagnostic device includes a piezoelectric sensor sheet having flexibility and configured to output a detection signal corresponding to an input vibration. A respiratory signal acquisition unit is configured to extract, as a respiratory signal, a signal of a vibration frequency caused by respiration from the detection signal detected by the piezoelectric sensor sheet. A power spectrum calculator is configured to obtain a power spectrum of a respiratory frequency band from the respiratory signal, and a signal corrector is configured to correct the detection signal such that in the power spectrum, a maximum value of a first-order frequency component of a respiratory waveform is not smaller than 1.5 times a maximum value of a second-order frequency component of the respiratory waveform to obtain the respiratory signal.

    Abstract: A linear friction welding method capable of accurately controlling a welding temperature and capable of lowering the welding temperature is provided. The present invention is a linear friction welding method comprising: a first step of forming a welded interface by bringing one member into contact with the other member; a second step of repeatedly sliding one member and the other member on the same locus and discharging flash from the welded interface in a state where pressure is applied substantially perpendicularly to the welded interface; and a third step of forming a welded surface by stopping the sliding and setting the pressure to be not less than the yield stress and not more than the tensile strength of one member and/or the other member at a desired welding temperature.
