  • Publication number: 20240375233
    Abstract: A relative displacement-specifying unit specifies relative displacement between a jig and tool based on measurement values of displacements of the tool and jig. A position determination unit determines whether the jig and the tool are positioned at jig and tool calibration points based on the measurement values. A displacement correction unit corrects the measurement values based on captured images of the jig and tool calibration points when it is determined that the jig and the tool are positioned at the calibration points. A contact determination unit determines whether the tool contacts the workpiece based on a measurement value related to main shaft flexure. A tool data correction unit corrects tool data based on the relative displacement when it is determined that the tool contacts the workpiece. A control unit generates a control command to control the jig or the tool based on the relative displacement, workpiece shape, and tool data.

  • Patent number: 8226344
    Abstract: An angle formed on a side of a bucket by a first line segment that connects a first pivot region of a bell crank relative to a boom and a second pivot region of the bell crank relative of a connecting link and a second line segment that connects the first pivot region and third a pivot region of the bell crank relative to a tilt cylinder is no more than 206.5°. An angle formed by the second line segment and a line segment that connects the third pivot region and fourth a pivot region of the tilt cylinder relative to a structural body is, in a fork-attached state, no more than 72.3°. When a pivot region of the fork relative to the boom is substantially 1.5 m from the ground, a lower end of the bell crank is located higher than a lower end of the fork.

  • Patent number: 7967547
    Abstract: In a work machine 1, an angle ? formed by a first line segment L1 connecting a pivot position Y of a bell crank 11 on a boom 10 and a pivot position X of the bell crank 11 on a connecting link 13, and a second line segment L2 connecting the pivot position Y of the bell crank 11 on the boom 10 and a pivot position W of the bell crank 11 on the tilt cylinder 12 on a bucket 20 side is 176 (deg) or less, an angle ? formed by the second line segment L2 and a line segment L3 connecting the pivot position W of the bell crank 11 on the tilt cylinder 12 and a pivot position Z of the tilt cylinder 12 on a working structure is 72.3 (deg) or less, and, in a case where the bucket 20 is set at a top position, a lowering angle ? of a front end of a lower surface of the bucket 20 is 4.5 (deg) or less.

  • Patent number: 6148909
    Abstract: A temperature control system which performs control of an object whose temperature is to be controlled as accurately as possible. The system comprises: a chiller located in a fluid circulating and supplying system, for cooling a thermal fluid returning from a vacuum chamber, a first flow control valve located in the fluid circulating and supplying system in a position between the chiller and the vacuum chamber, a bypass passage for splitting and supplying thermal fluid returning from the vacuum chamber to a position between the first flow control valve and the vacuum chamber, before it reaches the chiller, a second flow control valve located in the bypass passage, and a halogen lamp heater located in the fluid circulating and supplying system in a position between a confluence point of the bypass passage and the vacuum chamber, for adjusting the temperature of the thermal fluid passing therethrough to a set temperature.
