  • Publication number: 20210323147
    Abstract: A picking apparatus in an embodiment includes: a gripper, an arm, a detector, and a control unit. The gripper picks and grips an object to be conveyed. The arm moves the gripper and causes the gripper to convey the object to be conveyed. The detector is attached to the arm and senses a force applied to the gripper. The control unit controls an operation of the gripper and the arm. The control unit includes a calculator and a subtractor. The calculator calculates a gravitational force and an inertial force applied to the gripper when the gripper grips and moves the object to be conveyed using an arithmetic expression including a coefficient determined in accordance with a mass of the object to be conveyed. The subtractor subtracts the gravitational force and the inertial force calculated by the calculator from a force applied to the gripper sensed by the detector.

  • Patent number: 10824005
    Abstract: Provided is a display device enhancing an image contrast ratio and thereby enhancing display quality without being affected by ambient brightness. The luminance of an image displayed on a first liquid crystal panel in a display gradually increases in slope as a gradation value increases from 0 to 255. Accordingly, luminance A for the gradation value 0 is the same as conventional luminance a for the gradation value 0. However, luminance B for the gradation value 255 is higher than conventional luminance 2b for that gradation value, resulting in a high contrast ratio as expressed by the following equation: B:A=B/A:1>2b/a:1.
