A display device of the present invention is provided with a display control unit which executes a display control process for controlling the operation of a prescribed display destination and for displaying multiple N-dimensional graphs on the display destination. In the N-dimensional graphs, predetermined multiple types of explanatory variables are each defined as a display candidate explanatory variable, and predetermined multiple types of objective variables are each defined as a display candidate objective variable, and each of the graphs shows a relationship between a Q-1 type (Q is an integer of 2 or more) explanatory variable among the display candidate explanatory variables and one type objective variable among the display candidate objective variables. The multiple N-dimensional graphs include a first graph and a second graph that have a common explanatory variable and different objective variables. The display control process includes a process which involves, when a prescribed condition is satisfied regarding acquisition of fixed-value change information including auxiliary explanatory variable information for designating one or more of auxiliary explanatory variables as values to be changed and information indicating current variable values, updating the first graph and the second graph to be displayed on the display destination to changed graphs in which the values of the auxiliary explanatory variables indicated by the auxiliary explanatory variable information have been changed to the current variable values indicated by the fixed-value change information.

Abstract

A freeze-drying device includes a controller configured to control depressurization of containers filled with a liquid including a raw material and a medium to freeze the liquid from a liquid surface. The freeze-drying device also includes a gas capture pump configured to exhaust a freeze-drying chamber accommodating the containers, and a positive-displacement pump configured to discharge gas from a space accommodating the gas capture pump. The controller executes an exhaust mitigation process that performs the depressurization at an exhaust capability that is less than a rated exhaust capability of the freeze-drying device. The controller uses a partial pressure value of the medium to determine when the exhaust mitigation process ends. The controller maintains an exhaust speed of the gas capture pump and decreases an exhaust speed of the positive-displacement pump in the exhaust mitigation process.

Abstract

[Problem] To improve step coverage of a coating film. [Solution] To use a film formation device equipped with a first electrode, a second electrode, a first power supply source, a second power supply source, and a phase adjuster. The first power supply source includes a first high-frequency power source that outputs first high-frequency power, and a first matching circuit that is connected between the first high-frequency power source and the first electrode. The second power supply source includes a second matching circuit that outputs a second high-frequency power lower than a first high-frequency power with the same period as the first high-frequency power. The second high-frequency power is caused to be output from the second high-frequency power source, and the phase adjuster is operated to provide a phase difference θ to a phase of the first high-frequency power and a phase of the second high-frequency power. A voltage value Vpp of the second high-frequency power and a capacitance value C1 of a first variable capacitor are detected that correspond to the phase difference θ in a state where the output impedance of the second high-frequency power source and the load-side impedance connected to the second high-frequency power source are matched to each other. The voltage value Vpp and the capacitance value C1 are selected in combination in a prescribed range of the phase difference θ.

A freeze-drying device includes a controller configured to control depressurization of containers filled with a liquid including a raw material and a medium to freeze the liquid from a liquid surface. The freeze-drying device also includes a gas capture pump configured to exhaust a freeze-drying chamber accommodating the containers, and a positive-displacement pump configured to discharge gas from a space accommodating the gas capture pump. The controller executes an exhaust mitigation process that performs the depressurization at an exhaust capability that is less than a rated exhaust capability of the freeze-drying device.

Abstract

[Problem] To freeze droplets of a raw material liquid while maintaining an ultra-high cooling speed with a short fall distance so as to not alter characteristics of a solute or dispersoid. [Solution] A vacuum freeze-drying method according to an embodiment of the present invention comprises: a step for ejecting a raw material liquid into a vacuum tank from a spray nozzle to produce frozen fine particles due to self-freezing of the raw material liquid, and drying the frozen fine particles thus produced to produce dried powder. The raw material liquid is ejected from the spray nozzle such that the initial ejection speed of the raw material liquid from the spray nozzle is 6-33 m/sec with the inside of the vacuum tank maintained at a partial water vapor pressure corresponding to the spontaneous freezing temperature of the raw material liquid. When the maximum diameter of the frozen fine particles thus produced exceeds a predetermined value, or when the droplets of the raw material liquid are not frozen, the ejection flow rate of the raw material liquid or the properties of the spray nozzle is adjusted such that frozen fine particles are produced so as to have a maximum diameter not more than the predetermined value.

Abstract

The present invention provides a technology capable of inhibiting, in a vacuum processing apparatus that conveys a plurality of substrate holders along a conveying path formed to have a projected shape on a vertical surface, the projected shape being a continuous ring shape, dust from being generated during conveyance of a substrate holder. The present invention includes, in a vacuum chamber 2, an anti-sag member 35 assembled to a first drive unit 36 provided on an outer side with respect to a conveying direction of the conveying path, the vacuum chamber 2 including a conveying path formed to have a projected shape on the vertical surface, the projected shape being a continuous ring shape, a single vacuum atmosphere being formed in the vacuum chamber 2. A travel roller 54 of the anti-sag member 35 travels while being guided and supported by a guide unit 17 that is provided below a return-path-side conveying portion 33c positioned on a lower side of a substrate holder conveying mechanism 3 and extends in a second conveying direction P2, and the first drive part 36 is configured to come into contact with a first driven unit 12 of a substrate holder 11 and drive the substrate holder 11 along the conveying path in the second conveying direction P2.

Abstract

[Problem] To homogenize film thickness distribution. [Solution] This film forming method involves film forming by sputtering on a substrate using a plurality, at least three, of rotary targets that each have a central shaft and a target surface and are provided, in the interior, with a magnet that is able to rotate about the central shaft. The plurality of rotary targets are arranged so that the central shafts are parallel to one another and are also parallel to the substrate. The film forming by sputtering is performed on the substrate as power is being fed to the plurality of rotary targets and the respective magnets of the plurality of rotary targets are being moved over an arc that has an A-point closest to the substrate about the central shafts. Magnets of at least a pair of rotary targets arranged at two ends, among the plurality of rotary targets, have a shorter duration of film forming in a region that is further apart from the center of the substrate than the A-point on the arc than a duration of film forming in a region closer to the center of the substrate than the A-point.
