Koichi Nagoya 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).

  • Patent number: 9964500
    Abstract: A defect inspection device is provided with an illumination optical system that irradiates light or an electron beam onto a sample, a detector that detects a signal obtained from the sample through the irradiation of the light or electron beam, a defect detection unit that detects a defect candidate on the sample through the comparison of a signal output by the detector and a prescribed threshold, and a display unit that displays a setting screen for setting the threshold. The setting screen is a two-dimensional distribution map that represents the distribution of the defect candidates in a three dimensional feature space having three features as the axes thereof and includes the axes of the three features and the threshold, which is represented in one dimension.

  • Patent number: 8417769
    Abstract: Conventionally, in a system where devices for handling multiple media data such as audio and video are present, there is a problem that the number of audio channels that can be processed at the gateway is limited. In light of this problem, this invention offers a gateway having distributed processing function for a telephone or a data processing system featuring the capability to request address conversion to another terminal within the system to replace the address of stream-type packet data such as audio and video meant for itself, and if the aforementioned terminal to which the request was sent responds that it can handle the requested processing, to notify the address of the terminal processing the address conversion to the terminal transmitting the stream-type packet data.

  • Patent number: 8154717
    Abstract: An optical apparatus for defect inspection having an illuminating optical system for irradiating illumination light beams on the surface of a specimen to form a beam spot and a detection optical system for detecting a reflection light ray originating from the beam spot comprises a storage unit in which the position and size of a standard particle of known size on a specimen for correction are stored in advance, a correction processing section which, when the correction specimen is used as an inspection target, correlates a detected scattering light quantity from the standard particle with the known size of standard particle stored at a corresponding position in the storage unit to prepare a correlation between the scattering light quantity and a true value, and a signal processing section which, when an inspection wafer is used as an inspection target, converts a detected scattering light quantity into a defect dimension.
