    Abstract: An operating condition for a manufacturing apparatus that manufactures a product using a variation amount input step is provided in which an input device inputs a variation amount related to a predetermined operating condition. A model reading step reads, from memory, a model in which an input is the operating condition and an output is a characteristic value of the product. A target characteristic value is input for the product; and a predicted characteristic value distribution is calculated, using the model, and reflecting the variation amount related to the predetermined operating condition. An objective function is calculated based on the predicted characteristic value distribution and the target characteristic value; and an operating condition exploration step is performed in which a processor explores the predetermined operating condition that reduces the objective function. An operating condition output step is performed of outputting an operating condition that is a result of the exploration.

    Abstract: The superconducting magnet device reduces the number of connections within and/or the number of wires leading out of a superconducting coil winding and promptly starts expending the magnetic energy in a superconducting coil operating in a persistent-current mode when the superconducting coil increases in temperature or transitions to normal conductivity. This invention provides a superconducting magnet device that has the following: a superconducting coil connected to an excitation power supply; a persistent-current switch connected to the superconducting coil; a heater that controls the temperature of the persistent-current switch; a current source that is connected in parallel with the persistent-current switch and has a different polarity from the excitation power supply; a driving circuit connected to the heater and the current source; and a signal-inputting means for inputting a signal to the driving circuit. The driving circuit operates the heater and the current source when the signal is inputted thereto.

    Abstract: This superconducting magnet includes: a superconducting coil that is formed by winding a first superconducting wire rod; a second superconducting wire rod, which is disposed by being thermally in contact with and electrically insulated from the superconducting coil, and which has a superconducting transition temperature that is lower than that of the first superconducting wire rod; voltage terminals that are disposed at a plurality of areas of the second superconducting wire rod; a voltmeter connected to the voltage terminals; and a switch circuit connected to the voltmeter. The switch circuit interrupts a current when receiving an output from the voltmeter, the current being one that is to be supplied to the superconducting coil.

    Abstract: Sample transferring can be securely and easily performed between an FIB device, an electron microscope, and an atom probe device, and atom probe analysis can be performed to a material that easily alters due to atmospheric exposure. A sample holder that holds a sample (12) is provided with an atmosphere-isolation mechanism that prevents the sample from altering due to the atmospheric exposure upon the sample transferring between the devices. There is provided a structure enabling of attaching and detaching a housing (21) of a sample holder leading end of a part of the atmosphere-isolation mechanism in an analytical vacuum device, such as the atom probe device.
