  • Publication number: 20200098546
    Abstract: Provided is an impedance matching device capable of promptly improving an impedance mismatch between a high-frequency power source and a load even when the impedance of the load continuously changes. An impedance matching device according to the present invention is for use in a high-frequency power system configured to supply a load with an output from a high-frequency power source via a matching circuit whose constant is mechanically changed, and the impedance matching device includes a matching condition value acquisition portion for acquiring a matching condition value indicating a matching condition between the high-frequency power source and a load, and a control portion for controlling an oscillation frequency of the high-frequency power source based on the matching condition value.

  • Publication number: 20190352113
    Abstract: A transport device moves a sheet member supported by adsorption portions to a space above a second table being a transport destination, and moves the adsorption portions in a direction of approaching the second table by reducing a speed gradually or stepwisely so as to bring the sheet member into contact with the second table. With this, a transport speed of the sheet member is improved, and air is prevented from entering a space between the sheet member and the table being a transport destination.

  • Publication number: 20190319190
    Abstract: Provided are a mask sheet frame body bonding apparatus that allows a mask sheet to be bonded to a frame body without producing a crease in a mask pattern by a simple method, and a manufacturing method of a vapor deposition mask. The mask sheet frame body bonding apparatus bonds the mask sheet provided with the mask pattern to the frame. The mask sheet frame body bonding apparatus includes grippers configured to hold gripper end portions of the mask sheet and apply a tensile force to the mask sheet, and a roller serving as a pressing members other than the frame and configured to press at least a side of the mask sheet subjected to tensile force that is opposite to the frame and is a front face of the mask sheet, between the mask pattern and holding positions of the grippers.

  • Publication number: 20190061877
    Abstract: A bicycle rear derailleur includes a base member, a chain guide, a movable member and a first link member. The base member is configured to be mounted to a bicycle frame at a frame mounting axis. The chain guide includes a first pulley rotatably arranged around a first pulley axis in a first pulley plane. The movable member pivotally supports the chain guide about a pivot axis. The first link member moves the chain guide between first and second lateral positions. The first lateral position is closer to a bicycle center plane. The first pulley plane intersects the first link member in a state where the chain guide is located at the second lateral position. The frame mounting axis is spaced from the pivot axis by a distance equal to or larger than eighty-nine millimeters when the chain guide is at the first lateral position.
