  • Construction machine
    Patent number: 11976442
    Abstract: A construction machine includes an attitude sensor that detects the current attitude of an upper turning body; a reference angular acceleration calculation unit that calculates a reference angular acceleration to be generated when an electric turning motor is driven by a torque command value generated according to the operation amount of an operation part; a reference gravity torque calculation unit that, on the basis of the current attitude and the deviation between an actual angular acceleration, calculates a reference gravity torque; a gravity compensation torque calculation unit that calculates a gravity compensation torque for compensating a torque component generated about the turning axis by the gravity in the current attitude; and a correction unit that corrects the torque command value by using the gravity compensation torque so as to cancel the torque component generated about the turning axis by the gravity in the current attitude.

  • Reflecting device, communicating pipe, exhausting pump, exhaust system, method for cleaning the system, storage medium storing program for implementing the method, substrate processing apparatus, and particle capturing component
    Patent number: 8727708
    Abstract: A reflecting device that enables to prevent infiltration of particles into a processing chamber. The reflecting device is disposed in a communicating pipe. The communicating pipe allows the processing chamber of a substrate processing apparatus and an exhaust pump to communicate with each other. The exhaust pump has at least one rotary blade. The reflecting device comprises at least one reflecting surface. The at least one reflecting surface is oriented to the exhausting pump.
