Latest Patents
Kato's latest patents include a noncontacting IC card that is powered by an external source. This innovative IC card features a RAM, a control circuit for managing access to the RAM, and a power supply circuit that receives energy from outside sources. The design includes a first voltage detector that generates a starting output when the supply voltage exceeds a predetermined first reference voltage. Additionally, a second voltage detector produces a control signal when the supply voltage surpasses a higher second reference voltage. An AND gate is incorporated to generate a RAM control signal, enabling the RAM to operate when both the starting and control signals are present.
Another of Kato's recent inventions is a hand type musical timepiece. This analog musical timepiece is designed with a hand that is driven by a step motor to visually indicate tones of a melody. It features a staff or keyboard pattern adjacent to an imaginary plane that the hand sweeps across. The device includes a melody playing mechanism and a normal-reverse rotation controller, allowing the hand to move in sync with the melody. The operations of time indication and tone indication are managed by a specialized circuit and a programmed microcomputer.
