Abstract: A blood rheology measuring apparatus has a measuring portion for measuring a flow velocity of the blood flowing in a blood vessel of a person in a mode of a Doppler shift signal by transmitting and receiving a wave to and from a surface of the person's skin. An information processing portion calculates an intensity at each of frequency components of the Doppler shift signal, extracts a maximum frequency in a signal at an intensity level equal to or larger than a threshold in the histogram or a maximum frequency when an integrated value from a low frequency component reaches a predetermined rate of a total thereof in the histogram, and provides a temporal change waveform of the extracted frequency. The blood rheology is analyzed by an area value of a portion at and above a line connecting a minimum value of one pulse waveform and a minimum value of a successive pulse waveform of the frequency waveform.

In the pulse detecting device, a detection sensitivity of the pulse is improved. A transmitting piezoelectric element and a receiving piezoelectric element are fixed onto a substrate by electrodes. The transmitting piezoelectric element is excited in response to an inputted drive voltage signal to generate an ultrasound and transmits the generated ultrasound to a living body. The receiving piezoelectric element receives an echo produced by reflecting the ultrasound transmitted into the living body by a blood flow of the living body and converts it into a voltage signal. A processing arithmetic unit compares the frequency of the ultrasound generated by the transmitting piezoelectric element with that of the echo received in the receiving piezoelectric element to thereby detect a pulse.

Abstract: In the steering apparatus and feed screw mechanism, by properly adjusting the screw-in distance of a pressing force adjusting screw 77, the arc-shaped contact surface 761 of a pressing member 76 can be pressed against the outer diameter portion 711 of a feed screw shaft 71 with a required pressing force due to the biasing force of a compression coil spring 78. As a result of this, a backlash between a feed nut 73 and feed screw shaft 71 can be removed. Therefore, the telescopic position adjustment and tilt position adjustment of a steering wheel 3 can be carried out smoothly, thereby being able to enhance the rigidity of the steering wheel 3 after execution of the position adjustment thereof.

Abstract: With respect to a conventional and general supersonic probe, it is necessary to apply a special patterning to a piezoelectric element, so that this involves a problem such that the supersonic probe is difficult to manufacture. Alternatively, in the case of bonding the conducting wire to the piezoelectric element with the conductive adhesive or the like, it is necessary to make the thickness of the conductive adhesive and the thickness of the conductive wire less than or equal to that of the above mentioned acoustic matching layer, so that it is very difficult to manufacture and the thickness of the acoustic matching layer becomes thicker than the optimum thickness. This involves a problem such that the detection sensitivity has been deteriorated.
