Latest Patents

One of his latest patents is an X-ray computer tomography apparatus. This invention comprises a high-voltage transformer that performs the increase and noncontacting transmission of power simultaneously, outputting a desired high voltage to generate X-rays at the rotatable gantry section. The high-voltage transformer is divided into a primary side, located on the static gantry section, and a secondary side that generates high voltage. A capacitor is connected to the secondary coil of the high-voltage transformer, forming a resonance circuit.

Another significant patent is an X-ray power supply utilizing A.C. frequency conversion. In this invention, an output voltage from an A.C. power source is input to a frequency converter, which increases the frequency. A plurality of small-capacity high-voltage transformers, each with a secondary winding of a small number of turns, are connected in parallel to the output terminal of the frequency converter. The outputs of these transformers are connected to high-voltage rectifier circuits, which are serially coupled to add the output voltages together, applying the result to an X-ray tube. The combinations of high-voltage transformers and rectifier circuits are molded into units with solid insulating material, including gel insulating material.
