  • Publication number: 20220260972
    Abstract: A machining center processes a section not to be corrected of a workpiece and a crankshaft bearing hole in a different position from the section not to be corrected and which is separated from an upper deck surface of the workpiece. The machining center supplies a coolant to the hole during processing and detects a temperature of the coolant. A control apparatus estimates the temperature of the coolant when a predetermined time elapses from a start of the processing to be a temperature of the workpiece, calculates a deformation amount of the workpiece due to thermal expansion, corrects a position of the hole with respect to the upper deck surface based on the deformation amount, and starts processing of the hole after the predetermined time. The predetermined time ends when a difference between a temperature near the hole and the temperature of the coolant falls within a predetermined range.

  • Publication number: 20200312050
    Abstract: A control device collects vehicle data indicating at least one of a state of a vehicle, a state of a driver of the vehicle, and a situation around the vehicle; acquires determination data created based on at least a part of accident vehicle data as the vehicle data collected when an accident or an accident sign operation occurs in the past in a plurality of vehicles. The control device determines whether the vehicle is in a danger state based on the vehicle data and the determination data. The danger state is a state where the accident or the accident sign operation is likely to occur. The control device controls an operation of the vehicle or at least a part of various devices mounted on the vehicle in a case where it is determined that the vehicle is in a danger state.

  • Patent number: 9491320
    Abstract: An impact reduction device includes a pressing mechanism in an open-close device to press a first member in a direction in which the first member returns to an initial state. The open-close device includes the first member independently rotatable around a shaft from the initial state to a first angle, and a second member integrally rotatable with the first member around the shaft from the initial state to a second angle greater than the first angle. The pressing mechanism presses the first member in the direction in which the first member returns to the initial state using a first force until the first angle is reached, and presses the first member in the direction in which the first member together with the second member returns to the initial state using a second force greater than the first force between the first angle and the second angle.
