Latest Patents

One of Kimura's latest patents is an ignition device designed for internal combustion engines that utilize various fuels, including hydrogen. This ignition device features an ignition coil with both primary and secondary coils, a power supply device, a switching element, a spark plug, and a limiting diode. The switching element is responsible for controlling the flow of primary current, while the spark plug generates a discharge at a gap, based on the high voltage induced at the secondary coil. The limiting diode includes a Zener diode that is forward-biased, ensuring that its breakdown voltage exceeds the maximum ON-state voltage derived from the primary coil's direct-current voltage multiplied by the turns ratio of the coils.

Another significant patent by Kimura is an optical-fiber incorporated longer-sized subaqueous unit. This innovative unit consists of optical fiber units arranged within or outside a plastic sheath surrounding the core body of longer-sized subaqueous units, such as power cables or water supply tubes. Each optical fiber unit is housed in a metal pipe, which is coated with a plastic material that has a higher melting point than that of the plastic sheath. Additionally, armoring iron wire bundles are provided outside the plastic sheath to prevent any buckling in the optical fiber units.
