    摘要： PROBLEM TO BE SOLVED: To provide a device for directing energy to a target volume of tissue.
    SOLUTION: This device for directing energy to a target volume of tissue includes: an inner conductor having a length and an outer conductor coaxially surrounding the inner conductor along the length. The outer conductor has a proximal portion and a distal portion. The distal portion of the outer conductor is provided with a plurality of apertures N defined therein for radiating energy, where N is an integer greater than 1, each aperture having a size and extending at an angle relative to a longitudinal axis of the outer conductor. At least one of the size and the angle of each aperture is varied in relation to the other aperture N-1 such that the energy radiated along the distal portion is substantially uniform.

    摘要： PURPOSE:To obtain an inductive communication cable line having an irradiation waveform to be used in both HF and MF bands by constituting an open line irradiating an electromagnetic field externally and a coaxial line not irradiating an electromagnetic field in alternate arrangement at a periodic interval. CONSTITUTION:The delay type open coaxial cable 1 and the coaxial cable 2 are connected alternately at each period length l. The cable 1 shows a focused waveform and an irradiated waveform is obtained with the same principle as the leakage coaxial cable by arranging alternately the open line and the coaxial line. Thus, the irradiation type induction communication cable whose electromagnetic field is inversely proportional to the root of the vertical distance rho, and this system is used for mobile communication in the frequency band of HF(30-3MHz) and MF band (3MHz-300kHz).

    摘要： PURPOSE:To attain more accurate information transmission, by inverting a transmission line in polarity at a suitable position to a signal having a certain frequency in the suitable point of the transmission line, and inserting a circuit network not inverting the said polarity to a signal having other frequency so as to prevent noise without generating a dead band. CONSTITUTION:In transmitting information from one end A to other end B, the phase is inverted after passing the information through a filter 41 to use a signal in frequency F1, and the information is reached to the other end B without producing a change in the content of information. On the other hand, the noise having a frequency close to the frequency F1 is inverted for the polarity at the left and right of the filter 41 and the phase is inverted, then the noise is cancelled and the amount of noise mixed in an information signal having the frequency F1 is reduced. That is, the defect of information signal having the frequency F1, low in the noise resistance is compensated. In transmitting the information to a mobile body 3 from transmission lines 1, 2, since the signal having a frequency F2 is used, the phase is not inverted even after passing through a filter 42. Thus, the information is transmitted continuously without producing the dead band near the filter 42.
