Latest Patents
One of his latest patents is the "Heat and pressure fuser with non-symmetrical nip pressure." This invention is a heat and pressure fusing apparatus designed to fix toner images to substrates such as plain paper. The apparatus features two nip forming members that create a nip with an asymmetrical pressure profile. This design allows for a gradual increase in pressure, ensuring that toner images are first subjected to low pressure before being forced into the substrate as the toner begins to flow.
Another significant patent is the "Fusing system with unblended silicone oil." This innovation involves fusing toner images to a substrate using a heated fusing member with a silicone elastomer fusing surface. The fusing surface is coated with a toner release agent that includes an unblended polydimethyl siloxane, which has a specific kinematic viscosity range. This technology enhances the efficiency of the fusing process, ensuring high-quality results.
