TETSUHARU MIWA 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).

  • Light emission apparatus, object information detection apparatus, optical path adjustment method, object information detection method, and light modulation unit
    Patent number: 10741987
    Abstract: A light emission apparatus comprises a light source that emits coherent light, a light modulation unit, a reflector, and a first light reception part. The reflector comprises a first reflection surface that is a part of a spherical surface and a second reflection surface that is different from the first reflection surface. Modulated light modulated by the light modulation unit is incident on the first reflection surface and its reflected light is emitted to an object. Unmodulated light that is not modulated by the light modulation unit and is reflected from the light modulation unit is incident on the second reflection surface and its reflected light is received by the first light reception part.
    Type: Grant

  • Liquid-crystalline compound and organic semiconductor device containing the compound
    Patent number: 8480926
    Abstract: Disclosed is a visible light-transmissive liquid-crystalline compound having good hole and electron-transport characteristics and useful as an organic semiconductor material. The compound is represented by a formula (1): wherein R independently represents hydrogen, or alkyl having from 1 to 24 carbon atoms, and any —CH2— in the alkyl may be replaced by —O—, —S—, —CO— or —SiH2—, any —(CH2)2— may be replaced by —CH?CH— or —C?C—, and any hydrogen may be replaced by halogen; Ar represents naphthylene, anthrylene, phenanthrylene, or phenylene; and every hydrogen in phenylene is replaced by halogen, and any hydrogen in naphthylene, anthrylene and phenanthrylene may be replaced by halogen.
