Latest Patents

Among his latest patents, the "Pulse Signal Delay Circuit" stands out. This invention comprises a first pulse edge delay circuit that generates a first delay timing signal by detecting the rising edge of an input pulse signal and delaying the detection timing by a constant delay time multiple times. Additionally, a second pulse edge delay circuit generates a second delay timing signal by detecting the falling edge of the input pulse signal, also delaying the detection timing by the same constant delay time. The invention includes a delay pulse signal generating circuit that outputs delay pulse signals based on the first and second edge detection delay timings.

Another notable patent is the "Preparation of Flexible Copper Foil/Polyimide Laminate." This process involves applying a polyamic acid varnish onto a very thin copper foil, semi-drying the varnish, and laminating a polyimide film to the varnish-coated copper foil using a hot roll press. The laminate undergoes heat treatment for solvent removal and imidization in a controlled oxygen atmosphere. The resulting polyimide adhesive layer has a thickness of up to 6 micrometers, with the total thickness of the polyimide film and adhesive layer reaching up to 25 micrometers.
