Akira Tohyama 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: 8097563
    Abstract: The present invention provides cyclohexanedione-based agricultural-chemical emulsion compositions where active ingredients of agricultural chemicals are emulsified and dispersed in spraying water, especially cyclohexanedione-based agricultural-chemical emulsion compositions where alkylphenol derivatives are not used in emulsifiers and emulsification stability and preservation stability of technical products are favorable. The cyclohexanedione-based agricultural-chemical/herbicidal emulsions where preservation stability of active ingredients of agricultural chemicals and emulsifiability are favorable are obtained by using an amine salt of alkylbenzenesulfonate with poor water solubility as an emulsifier.
    Type: Grant

  • Patent number: 6904164
    Abstract: A method of quickly and accurately inspecting the stitching accuracy at which regions of a lithographic pattern are stitched at boundaries. The numerous regions of the lithographic pattern are exposed or delineated, one at a time. Inspected regions are scanned with a charged-particle beam to detect secondary electrons. The obtained signal is stored as an inspected image in an image memory, together with positional data about the inspected regions. After completion of acceptance of images from all the inspected regions, the inspected image is compared with a separately prepared reference image by an image processing unit. Pattern elements in the inspected regions corresponding to the reference image are extracted. Deviations at field boundaries or the like can be detected from the relative positions of these pattern elements, if any.

  • Patent number: 4636843
    Abstract: Deflection control apparatus for a beam index color television receiver includes a phase-locked loop for synchronizing an oscillating signal with an index signal generated by an electron beam scanning index stripes on the screen of the cathode ray tube of the receiver. The oscillating signal is supplied to a color switcher so that the scanning electron beam is modulated with color information corresponding to the respective color phosphor stripe being scanned. An error signal representative of the horizontal scanning speed of the beam is supplied to a deflection device to cause the generation of a compensating magnetic field to correct for non-linearities in the scanning speed. A compensation circuit delays the error signal so that the elapsed time from the detection of the scanning of one of the index stripes to the time of generation of the compensating magnetic field in accordance therewith equals one horizontal line period.
