I have had hundreds of ideas for inventions written up in my private notebooks, but only a few have been developed fully. For my De-diffraction research please look in the Physics pages. For my 3 Dimensional Drawing Instruments see the 3DD pages. The following links open pdfs and new browser pages. Please use the browser back arrows to return to this page.

3 Dimensional Drawing Instrument (Japan Patent No. 762196 . 50.3.24)
This is the only patent I obtained for the basic idea of the 3DD as described in various articles in the 3DD section.
Dediffraction Method (US Patent 1992)
See the Physics and Maths section for articles about this invention.
Perspective Drawing Instrument (US Patent 1987)
This is a mechanical device that very easily converts the plan of a structure into a perspective drawing seen from a given point in one, two or three point perspective. See detains in the article "3 Dimensional Drawing Machines" in the 3DD section.
Dediffraction Method Improvement (US Patent 1995)
See the Physics and Maths section for articles about this invention.
Arabic Printing Type Improvement (UK Patent 1965)
In the days of metal-cast printing type, this invention provided special characters, common endings of several letters, that abridged the total variations needed to print Arabic letters in their initial, middle and ending variants.
Binocular camera focusing (Japanese patent application 1983)
The idea behind this invention is to use two eyes with a camera viewfinder system that 'projects' a luminous cursor in 3D visual space. As the camera's focus changes in depth, say at 65 cm. the visual cursor will follow suit appearing to float at that depth. This makes it ideal for example for tracking a video scene in depth maintaining focus at precisely determined locations.
Shadow drawing instrument (Japanese patent appliction 1982)
This invention is for a mechanical system to assist the architect to draw the shadow of a point in a structure at a given hour and day of the year.
  super-microscope-thmb.jpg My 1983 idea for a super-resolving time-resolved microscopy that independently won the 2014 Nobel Prize in Chemistry.
Full details of how I noted an idea in my notebook, mentioned it briefly in a research contest application to famed microscope manufacturer Zeiss in 1996. To my surprise and pride the concept won for others the Nobel, and Zeiss is building state-of-the-art microscopes based on the same idea.
