Latest Patents

Yamashita holds a patent for a "Load cell and temperature correction of the same." This invention provides a method for correcting a load cell by preventing a beam member, which has an insulator film, from being trimmed by a laser beam during the laser trimming process. The load cell features a span resistor member and a zero point resistor member, both formed separately from the beam member. Each member includes a span temperature correcting thin film resistor and a zero point balance temperature correcting thin film resistor, which are applied to the insulator film on the beam member. These thin film resistors are connected to a bridge circuit and are trimmed with a laser beam to ensure accurate temperature correction.
