Abstract: An automatic diagnostic apparatus with a stethoscope is disclosed in which the name of a disease is automatically determined and recorded based on auscultated sounds. Standard data of auscultated sounds for cardiovascular diseases, respiratory diseases and gastrointestinal diseases are inputted into a computer beforehand. Then the waveforms of the auscultated sounds from stethoscoping a patient are converted into digital data and inputted into a computer, and the digital data signals are compared, with searches, with the standard data which have been inputted into the computer in advance. By this process the names of diseases are determined, and the names of diseases thus determined are automatically recorded in a recording device and displayed on monitors so that treatment can initiate swiftly with enhanced credibility of the objective diagnostic process through consensus between the physician and the patient.

Abstract: A power control system for an AC electric arc furnace. The control system includes variable reactors located intermediate a furnace power supply and arc electrodes that are height adjustable. The control system monitors operating characteristics of the furnace that are indicative of the active power consumption of the furnace and adjusts the variable reactors and the electrode height so as to minimize variations in the active power consumption. Loss of electrode arc can be predicted and countered by lowering the electrodes and decreasing the reactance of the variable reactors.

Abstract: An apparatus and system for using magnetic fields to heat magnetically susceptible materials within and/or adjacent to adhesives, resins, or composites so as to reversibly or irreversibly bond, bind, or fasten opaque or non-opaque solid materials to one another. The system makes use of the effect that alternating magnetic fields induce eddy currents and generate heat within susceptors, and the effect that alternating magnetic fields additionally induce magnetic hysteresis that occurs in magnetic materials and thereby generate heat. An induction heating tool is used to emit the magnetic field at its work coil, and an electronic controller measures the energy being used by a power converter that generates the alternating current driving the work coil which creates the magnetic field. The distance between the susceptor and work coil is repeatedly analyzed based upon the power converter's input energy, and the work coil is driven at a repeatedly corrected power level during the heating cycle.
