FlexScan CRT monitor

EIZO FlexScan E67T, CRT PC monitor purchased in 1998. I brushed inside the monitor to clean up dusts piled up. It looks that the monitor is made with great care, all parts used are made in Japan. Right now, such a CRT PC monitor is out of fashion, but its image quality is 19" CRT monitorsuperior.

Total eclipse of the moon

Total eclipse of the moon

F1.4/50mm, exposure time 30sec. 12/10 2011 23:00  The total eclipse of the moon in many stars, Aldebaran of the Taurus is seen to the direction of right bottom from the moon. It looks that 30 sec. exposure time is too long as stars don’t photograph  as dot shape.

Filed US Patent.

Filed US Paten through EFS web of USPTO(http://www.uspto.gov/). Specifications written in MS Word file and drawings written in MS power point file were converted to pdf files. When they are uploaded and validated. Validation error occurred on the drawing with the error of “page size is too large”. So far, the drawings were re-edited in MS Word format, then, the drawing could be passed. I am independent inventor and am not US citizen. USPTO is so nice for providing everybody in the world the opotunity for filing US Patent.
