Abstract: A multilayer ceramic capacitor includes a multilayer body including an inner layer portion including dielectric layers and internal electrode layers, and external electrodes on end surfaces of the multilayer body. The internal electrode layers each include a counter electrode portion and an extension electrode portion extending from the counter electrode portion toward the end surface and, when viewing the multilayer body in a cross section parallel to the width direction and the lamination direction, and when a maximum length in the width direction of a range in which one end in the width direction of the counter electrode portions is provided is defined as R1, and a maximum length in the width direction of a range in which one end in the width direction of the extension electrode portions is provided is defined as R2, a relationship between R1 and R2 is R2>R1.

Abstract: There is provided a development cartridge capable of switching development colors in a plurality of development cartridges without using development rack. A development cartridge of the present invention has a part of a drive member for switching development colors.

Abstract: An image forming apparatus according to the invention includes, in an apparatus body, an image carrier on which an electrostatic latent image is formed; and a rotary-type development unit being rotatable about an axis thereof and having a plurality of developing devices, which are used for developing the latent images formed on the image carrier. The rotary-type development unit is formed with cavities at an outer periphery thereof for receiving gas. The rotary-type development unit is rotated for sequentially advancing the gas in the cavities whereby the gas in the apparatus body is discharged out of the apparatus body.

Abstract: In a plasma processing apparatus having an upper electrode and a lower electrode in a vacuum chamber, a substrate receiving face of the lower electrode is formed to have a same convex surface as a deflected face of a substrate on condition that surface of the substrate is freely supported on an circumference thereof, and a uniform pressure is applied to the back of the substrate.

Abstract: A robot-teaching cassette is used to teach a robot to position a wafer cassette or a substrate cassette on a cassette-supporting base by the robot, without using the wafer cassette or the substrate cassette. The robot-teaching cassette includes a fixing section capable of being fixed in position on the cassette-supporting base, a moving section capable of being held with a robot-chucking section of the robot and moving separately from the fixing section, a light source provided on the fixing section or the moving section, and a target establishing a reference position, for receiving beams emitted by the light source and provided on the fixing section or the moving section.
