Latest Patents

Among his noteworthy inventions, Fujikawa has developed an advanced RF receiver. This device features an oscillator that outputs an oscillation signal, which is divided by a limiter into a branch signal. An amplifier then enhances this branch signal, which is processed through a frequency multiplier to generate a local oscillation signal. A mixer combines this signal with input from an antenna, followed by a band-pass filter that outputs an intermediate frequency (IF) signal. Ultimately, a detector produces a detected signal based on the detected IF signal, while a controller manages operations using the oscillation signal as a clock. This RF receiver is designed to be cost-effective, emphasizing affordability without compromising performance.

Another significant invention by Fujikawa is a transparent touch panel and its manufacturing method. The design incorporates an upper substrate with a conductive layer on its lower surface and a lower substrate with a conductive layer on its upper surface, creating a gap for optimal functionality. The two substrates are bonded together using a spacer that ensures durability and elasticity. This innovative design maintains a long usable life and facilitates a compact structure while ensuring the effective operating area is preserved.
