    摘要: An ultrasonic sector-scan probe comprises at least an array having a plurality of ultrasonic transducer segments, a window for transmitting and receiving ultrasonic waves and an ultrasonic wave propagation medium filled in a front space between the array and the window. A group of the ultrasonic transducer segments are selectively driven as an aperture and ultrasonic waves emitted therefrom are converged into a beam for transmission and reception. By partly or entirely changing the segments in the group with the ones outside the group the scan line is shifted to a new angle, and a member under test contacted with the window on the outside thereof is sector-scanned by the ultrasonic beam. The array is arranged so that scanning lines of the groups intersect at one point in the window or in its vicinity for sector scan. And an acoustic lens is provided in the window or in its vicinity so that the ultrasonic beam may be converged almost over the measuring depth range of the member under test with/without phase control of the segments in the group. Furthermore, the array is arranged multidimensionally or in plural linear arrays so that the scanning lines of the groups intersect substantially at one point in the window or in its vicinity for sector scan, thereby performing sector scan of at least two sections and/or three-dimensional sector scan.

    摘要: The present invention relates to an apparatus which determines the distribution of the attenuation slope coefficient on a real time basis using the center frequency shift. The phase difference between a received signal and a reference signal is determined using EXCLUSIVE OR gates or an inverse trigonometric relation stored in a ROM. The phase difference is input to a differentiator which outputs the center frequency shift of the received signal on a real time basis. The center frequency shift is input to another differentiator which outputs the attenuation slope coefficient. Thus, the attenuation slope coefficient is determined using simple hardware and without calculating the power spectrum and the first moment.

    摘要: A broadcast acknowledgement method and system wherein a digital information signal, generated in order to indicate the content with regard to a present broadcast program (for example, a commercial broadcast program on television, radio or CATV), is superimposed on the voice signal of said program for broadcast and the composite signal transmitted to the receiving station, where it is processed to retrieve the digital information signal. Thereby, it can be confirmed whether or not the particular program has been broadcast or not. The method generally comprises the steps of removing the particular frequency band of the voice signal, generating the digital information signal by using some of the desired frequency signals within the particular frequency band of the voice signal, superimposing the digital information signal on the voice signal, transmitting the composite signal, extracting the digital information signal from the received signal at the receiving side, and processing the digital information signal so extracted to identify the particular program broadcast, and thus to obtain broadcast acknowledgement information such as sponsor's name, performers' name, time of broadcasting, etc. The broadcast acknowledgement system comprises, in several embodiments, a voice amplifier, band elimination filters, digital information generation circuit, various signal generators, and a mixing circuit; and, in another embodiment, a voice amplifier, band elimination filters, a digital information generation circuit, and a selector circuit.

    摘要: This invention relates to two methods treating such disease as AIDS. The first method includes administering the Trigger Factor such as TNF, which is defined as substance stimulating infected cells to increase HIV replication and hence subjecting the infected cells to death or the programmed death (apoptosis), further administering new-infection suppressor such as AZT and preferably inducer to migrate infected cells (lymphocytes) to the blood system from the lymphatic system, and then continuing extinction of the replicated HIVs by extracorporeal blood processing until all the infected cells die. The second method includes administering electroconductive and/or magnetic microparticles on the surface whereon of which such infectiously adhesive substance to HIVs and infected cells as CD4 is coated, and killing HIVs/infected cells adhered to the microparticles by heating the microparticles with electromagnetic field (wave) applied externally to the patient.
