Latest Patents

Yuki's latest patents include a light signal detecting circuit, a light amount detecting device, and a charged particle beam device. These inventions are designed to discriminate the signal component of a small amount of light from the noise due to dark current. The data-processing unit detects pulses from a digital voltage signal corresponding to the amount of light obtained by an amplifier and an A-D converter. It calculates the crest value as the maximum voltage of each pulse and stores the occurrence frequency of each calculated crest value in a frequency occurrence storage area. The data analysis unit compares a previously determined frequency lower limit with the occurrence frequency of each crest value, setting a pulse determination threshold to the first crest value whose occurrence frequency is equal to or smaller than the frequency lower limit. The threshold processing unit then outputs the digital signal higher than the pulse determination threshold.

Another notable patent involves a method and apparatus for removing burrs from joined billets in a continuous rolling process. This method includes joining the rear end of a preceding billet with the front end of a succeeding billet using a flash butt welding method while both billets are moving. It also involves grinding a burr on the welded part of the joined portion using multiple grinders while the billets are in motion. The grinding machine for continuously rolling a round billet includes a travelling body shuttling along the direction of movement, a turret ring rotatably supported by the travelling body, and several grinding devices arranged within a radius of the turret ring.
