Latest Patents
Kato's latest patents include a system for door entry control by wireless communication. In this vehicular entry control system, a code signal transmitter of a card carried by a driver modulates a signal received from a transmitter/receiver of a control unit mounted in a vehicle. The modulated signal is transmitted back to the control unit, which demodulates it. A microcomputer automatically unlocks the vehicle door when the demodulated signal is correct, indicating that the card is within the demodulating area. The system also includes a feature that prohibits automatic unlocking if the card is still present after a manual locking operation.
Another significant patent is for an optical hollow waveguide and the method for fabricating it. This invention involves forming a polyimide resin layer on the inner surface of a metal or non-metallic pipe that has a metal thin film. The polyimide resin layer is transparent to the wavelength band of laser light transmitted through the optical hollow waveguide. The fabrication process includes supplying a solution of polyimide precursor to the hollow internal of the pipe and heating it to create the resin layer.
