Latest Patents

Aizawa's latest patents include a flame detection device and a fire alarm system. The flame detection device features a detection element that converts infrared ray energy into an electric signal. It includes a first extracting unit that isolates signals within a specific frequency range, including the flicker frequency of a fire. Additionally, a second extracting unit captures signals from a higher frequency range, allowing for precise fire judgment based on the outputs of both units. This device effectively discriminates flames from other infrared energy sources, ensuring rapid and reliable fire detection without increasing product costs.

The fire alarm system comprises multiple components, including light emitting devices, polarizing filters, and light receiving devices. This system detects the ratio of parallel and perpendicular polarized light components scattered by smoke, which correlates with the type of smoke present. A calculation section processes this ratio, while a decision section compares it to preset reference values to determine the presence of a fire. This innovative approach allows for effective fire detection based on smoke characteristics.
