  • Patent number: 11191523
    Abstract: An ultrasonic-image-construction apparatus can construct an ultrasonic-tomographic image of a thin, layer-structured target object to be measured relatively easily and highly accurately in a manner in which such layered structure is easily understood. An ultrasonic transducer of an ultrasonic-image-constructing apparatus transmits ultrasonic waves to the target object. A reference substance makes contact with a base substrate, with such ultrasonic waves being incident on the target object via the base substrate, then receives an impulse response of an ultrasonic waveform. A computing means performs calculation to estimate acoustic-physical-property distribution in consideration of the multiple-reflections influence based on normalized-impulse information obtained from impulse-response information of such ultrasonic waveform incident on the reference substance and from impulse-response information of such ultrasonic waveform incident on the target object.

  • Publication number: 20210150709
    Abstract: This invention provides a signal-processing method that makes it possible to acquire, relatively easily and surely, a highly reliable normalized impulse-response signal without relying on the signal-correction processing after normalization. The signal-processing method of this invention includes a low-frequency extraction step, a high-frequency extraction step and a synthesizing step. In the low-frequency extraction step, only the low-frequency component is extracted from the spectrum of the first normalized signal NS1 obtained by normalizing the target signal Stgt in the time domain. In the high-frequency extraction step, only the high-frequency component is extracted from the spectrum of the second normalized signal NS2 obtained by normalizing the target signal Stgt in the frequency domain using the reference signal Sref.

    Abstract: A method and a system for producing a ring-shaped member. A punching process is carried out on an axial intermediate part of a first intermediate annular material so as to produce a pair of ring-shaped members. A punching step includes a step in which a first punching process is carried out over a first range of the axial intermediate part in the circumferential direction, and a step in which a second punching process is carried out over a second range of the axially-oriented intermediate part, which is at least partially different than the first range, in the circumferential direction. The first punching process is carried out such that at least one tab is formed. The second punching process is carried out such that at least one separate tab is formed, thereby producing the pair of ring-shaped members.
