Latest Patents

One of Toyoshima's latest patents involves a honeycomb structure that includes a body with porous partition walls defining multiple cells. These cells extend from an inflow end face to an outflow end face, forming through channels for fluid. The design features a first circumferential wall that is partially disposed around the partition walls, and a second circumferential wall that surrounds the outer side of the honeycomb structure body. Notably, there is no interface between the partition walls and the first circumferential wall, with a maximum thickness of the first circumferential wall ranging from 0.1 to 0.3 mm.

Another patent focuses on achieving precise exhaust gas control without being affected by fluctuations in the excess air ratio between engine cylinders. This honeycomb structure is designed with a plurality of cells separated by porous partition walls, which serve as fluid flow paths. It also includes a sensor plug-in hole on the outer peripheral surface, allowing for the insertion of a sensor, which is connected to at least one deep hole that communicates with the sensor plug-in hole.
