Latest Patents

One of his latest inventions is a flasher device for automotive vehicles. This device includes a printed circuit board enclosed in a casing, a B-terminal connected to a battery, an L-terminal connected to a direction indicating lamp, and an E-terminal connected to ground. A fixed contact of a relay section is attached to the L-terminal, and a current detecting resistor is connected between the B-terminal and a movable contact of the relay section. This design allows the main lamp current to flow from the battery to the lamp through the B-terminal, the current detecting resistor, the relay contacts, and the L-terminal, thus avoiding the flow of main lamp current through copper foils formed on the printed circuit board.

Another significant patent is a system for indicating interruption in the operation of automotive lamps. In this system, a current winding is connected between an electric current source and automotive lamps to generate a magnetomotive force in response to the amount of current flowing through it. A voltage winding is connected in parallel with the combination of the current winding and the automotive lamps to generate an opposite magnetomotive force. A reed switch is disposed adjacent to the current and voltage windings and is energized to close or open based on the net magnetomotive force. An indicating lamp is operatively related to the reed switch, which is energized when the net magnetomotive force becomes lower than a predetermined value due to the interruption in operation of at least one of the lamps. A zener diode is also connected in series with the voltage winding to enable indication of the interruption when all of the automotive lamps are inoperative.
