Patents by Inventor Hiroki Ohkouchi

Hiroki Ohkouchi 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: 10535385
    Abstract: A semiconductor integrated circuit includes a register, a detection circuit, and a generation circuit. The register stores a detection start timing of a reference delay amount based on a first clock during a first period. The first period is a period in which the first clock starts to be input. The detection circuit has a plurality of delay stages. The detection circuit detects the reference delay amount at the start timing during the first period and obtains the number of delay stages corresponding to the reference delay amount. The generation circuit adjusts a duty ratio of the first clock based on the number of delay stages obtained by the detection circuit and generates a second clock during a second period. The second period is a period continuing from the first period.

  • Publication number: 20030087597
    Abstract: An object of this invention is to reduce the capacity of an air pressure supply equipment in a semiconductor manufacturing factory without decreasing the productivity of a manufacturing system. To achieve this object, the manufacturing system includes a plurality of processing apparatuses (1, 2, 3), an air pressure supply apparatus (4) which supplies a gas pressure to the plurality of processing apparatuses, and a control apparatus (7) for controlling the plurality of processing apparatuses. The control apparatus creates operation schedules for the plurality of processing apparatuses on the basis of temporal change information of an air pressure consumption amount corresponding to the operation order of each of the plurality of processing apparatuses so as to prevent the sum of air pressure consumption amounts of the plurality of processing apparatuses from exceeding the air pressure supply ability of the air pressure supply apparatus.
