  • Publication number: 20220134542
    Abstract: A position/force controller performs a first conversion for distributing control energy to at least one of velocity or position energy and force energy, in accordance with a function to be realized, based on velocity (or position) and force information, which correspond to information relating to a position based on an operation of an actuator, and information serving as reference of control. The position/force controller calculates at least one of a velocity or position control amount and a force control amount based on at least one of the energies obtained through the distribution. The position/force controller integrates the calculated control amounts, performs a second conversion, and determines input to the actuator. The position/force controller performs a process, corresponding to increasing or decreasing performed on at least one of the velocity or position energy and the force energy together or independently, with satisfaction of a condition set for the control energy.

  • Patent number: 8693854
    Abstract: A uniform voltage is applied to loads even to other than a multiple of three loads made of heating lamps connected in parallel to each other, without causing any burden on a primary side. The number of loads is divided into a multiple of three and a multiple of two. A three-phase AC voltage is applied to three primary windings, which are connected as a Y-connection or a ?-connection. Secondary windings, which are each magnetically coupled to a primary winding of a plurality of three-phase transformers and have the same number of turns, are connected with the multiple of three loads.

  • Patent number: 8521013
    Abstract: A technology to control temperature of a large substrate to be heated. A temperature sensing device is disposed lateral to a region where a radiation heater faces a substrate to be heated inside a heating chamber. A heating device has the heating chamber, the radiation heater, a power-supply device, a substrate-holding device, a control device, and the temperature sensing device. A control program is built into the control device, according to which the power-supply device controls the power applied to the radiation heater to generate heat such that the temperature of the temperature measurement substrate detected by a thermocouple of the temperature sensing device becomes a set temperature. Furthermore, a circulation passage is disposed in close contact with the temperature-sensing device, and with a coolant flowing through the circulation passage, the temperature of the temperature measurement substrate can be cooled from the set temperature to an initial temperature.
