Latest Patents

Oka is credited with 1 patent, titled “Optical deflector.” The invention uses a movable plate connected to two fixed portions by elastic supporting members arranged substantially symmetrically around the plate’s center line. A Wheatstone-bridge measuring portion, comprising two active resistors and two reference resistors, detects the movable plate’s angular displacement. At least one resistor element is placed on an elastic supporting member, with all four resistor elements positioned in an area with isothermal characteristics. This arrangement is intended to reduce strain-gauge temperature drift caused by temperature gradients and enable more accurate detection of the mirror surface’s angular displacement.
