Tomoyuki Mamiya has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).
Abstract: A one-piece LC type optical fiber adapter is provided. The LC type adapter of the present invention has fewer parts than a conventional one. Therefore, it is simpler and easier to assemble the LC type adapter of the present invention. In addition, the main body of the LC type adapter is unitary thereby avoiding the prior art problem that the stresses cause the two halves of the adapter to separate from each other after time.

Abstract: An optical fiber LED assembly for coupling light from a light source element to an optical fiber via a rod lens with distributed refractive index provides improved stability by controlling deterioration in the optical coupling efficiency of the assembly with a lapse of time. The light source element includes a light emitting element which radiates light through a transparent aperture-covering plate of a can in which it is located. The light source element is supported by a first cylindrical holder. A second cylindrical holder supports a rod lens with distributed refractive index at one end thereof and accepts and supports the distal end of an optical fiber ferrule. The second cylindrical holder is inserted and fixed in the first cylindrical holder, the rod lens with distributed refractive index being directed toward the transparent aperture-covering plate of the light source element.
