Latest Patents

One of Ikegawa's latest inventions is a water content detecting device for diapers. This device is designed for various types of diapers, including reusable cloth and disposable paper options. It features a sensing unit that detects the degree of wetness and an informing unit that transmits this information to a caregiver at a remote location. The sensing unit is cleverly integrated into the diaper and consists of a water impermeable upper sheet, a water permeable lower sheet, and two metal layers that run parallel to each other. One of these metal layers is insulated electrically. The informing unit connects to the sensing unit and includes a water content detecting circuit that measures changes in electrostatic capacitance, along with a waveform shaping circuit and an oscillating circuit.

Another significant patent by Ikegawa is related to an electrolytic capacitor. This capacitor comprises an anode foil, a cathode foil, and electrolytic paper placed between them. The unique aspect of this electrolytic paper is that it is formed with discontinuous projections on one side and corresponding recesses on the other side, achieved through a secondary working step. This process results in a thicker paper with lower density compared to its untreated state.
