Latest Patents

Touma's latest patents include an optical data recording disc and system. This invention features a protrusion forming layer on a gas generating metal layer, which is itself formed on an optically polished disc. An optical beam modulated by data impinges on the gas generating metal layer, causing it to locally evaporate and produce gas. This gas expands to create protrusions in the protrusion forming layer, which represent the recorded data. This innovative approach allows for immediate data reproduction, enabling the detection of failures in the recording device or disc right after the data is recorded. Another significant patent is the boron-coated diaphragm for use in loudspeakers. This diaphragm is constructed from a substrate shaped into a diaphragm configuration, with a coating layer made of boron or its alloys applied to the surface.
