Abstract: An adaptive digital filter has a series of delay elements for imparting a unit delay of one sampling interval to successive input data samples in order to concurrently obtain a set of data samples of different sampling items. Each set of data samples are multiplied by respective coefficients, and the resulting multiplier outputs are added together into a filter output for comparison with a reference signal. The coefficients are renewed a preassigned number of times during each sampling interval, and the last renewed coefficients are used for each new set of data samples. For such coefficient renewal, a plurality of arithmetic circuits are connected in parallel for simultaneously performing the necessary computations for the renewal of all the coefficients.

Abstract: A heating apparatus for hyperthermia utilizes electromagnetic waves for locally heating cancerous cells within a living body. Electromagnetic waves output from a single electromagnetic wave generating means are branched into a plurality of branched electromagnetic waves, which are respectively employed to conduct hyperthermia treatments for a plurality of patients. The whole of the hyperthermia system is controlled in a concentrated fashion from a single section by means of time-division multiplexing. It is therefore possible for a plurality of patients to be subjected to hyperthermia treatment at the same time and in parallel with each other, even when the conditions of these patients differ from one another. Further, it is advantageously possible to simplify the arrangement of the system as a whole and stabilize the control of the system.

Abstract: The applicator used in this invention functions as an antenna for delivering electromagnetic energy into a living body. The applicator is supported by a supporting mechanism through a supporting device. The applicator can move to and stop at a position through the action of this supporting mechanism. A cooling section is provided on the contact surfaces of the applicator and the living body so as to protect normal cells on the surface of living body. This cooling section is additionally provided with a coolant circulating device, which enables to continuously perform hyperthermia for a long period of time. The coolant circulating device has a pressure reducing mechanism to counter the fluctuations in fluidal pressure, and further, provided with a deaerating device for preventing the air from stagnating therein. Furthermore, in the heating apparatus for hyperthermia as disclosed in this invention, the supporting mechanism, and electromagnetic wave producing source and a general control section are separate from one another, thereby facilitating the use of the apparatus.

Abstract: A frequency synthesizer includes a phase detector for comparing a reference frequency with a feedback frequency, a filter connected to the phase detector for permitting the passage of low frequency therethrough, a voltage controlled oscillator connected to the filter, a multistage frequency converter for receiving the oscillator signal from the voltage controlled oscillator as an input, and a divider for dividing the output of the multistage frequency converter to form the feedback frequency. The multistage frequency converter includes a plurality of frequency converters connected in series or parallel to each other, each of the frequency converters being adapted to perform a non-integer division. The division ratio can be set arbitrarily and finely. Thus, the feedback frequency inputted to the phase detector can be maintained constant and yet higher, irrespectively of the output frequency of the frequency synthesizer. Therefore, the reference frequency can be also maintained higher as is the feedback frequency, irrespectively of the frequency interval in the output frequency of the voltage controlled oscillator. This enables the acquisition time to be greatly reduced.

Abstract: An adaptive filter system has a first and a second filter subsystem of like construction, each having a series of delay elements for imparting a unit delay of one sampling interval to successive input samples in order to concurrently obtain a set of input samples of different sampling times. Each set of input samples are multiplied by respective coefficients, and the resulting values are added together for comparison with a reference signal. The coefficients are updated for each new set of input samples. For such updating, the first subsystem uses the step gain that is fixed at one, whereas the step gain used by the second subsystem is varied with time for faster convergence and smaller convergence error.
