Abstract: A multilayer varistor has a stack structure including a plurality of layers stacked in a third direction. The multilayer varistor includes a first internal electrode electrically connected to a first external electrode, a second internal electrode electrically connected to the second external electrode, and a third internal electrode electrically connected to the third external electrode. The first internal electrode is disposed between the second internal electrode and the third internal electrode in the third direction.

Abstract: According to one embodiment, provided is an automatic document feeder including a conveying unit, a first tray, a storage unit, and a paper discharge guide. The conveying unit is configured to convey paper to the paper discharge tray. The first tray is a paper discharge tray on which paper discharged by the conveying unit is stacked. The storage unit is a groove-shaped hole provided below the first tray. The paper discharge guide is a member for guiding paper having a predetermined size discharged by the conveying unit to the storage unit.

Abstract: A test device is used to test photosensitivity of a skin. The test device is provided with an irradiation unit including a plurality of light irradiation units arranged in a first direction. The plurality of light irradiation units output, in a second direction intersecting the first direction, irradiation light beams that mutually differ at least in one of wavelength characteristics and intensity. The irradiation unit is configured such that intensities of the irradiation light beams output from the plurality of light irradiation units are progressively smaller in the first direction.

Abstract: A paper discharge tray includes a placing part on which a recording medium discharged from a paper discharge part is placed; and a projection which is provided on the placing part and includes plural apexes arranged in a paper discharge direction of the recording medium.

Abstract: An auto document feeding device of an embodiment includes triple paper discharge rollers forming an upper paper discharge port for discharging a document at the time of one-sided reading and a lower paper discharge port for discharging a document reversed at the time of both-sided reading. A flap which covers the lower discharge port by its own weight and opens the lower discharge port by being pressed by the document discharged from the lower discharge port is provided on a shaft member of the triple paper discharge rollers.

Abstract: A sheet feeder in an image forming apparatus of this invention is provided with special sheet ribs for controlling both sides of special sheet on a sheet guide provided between a manual sheet supply tray and aligning rollers. This is to satisfactorily guide ordinary sheet and special sheet such as post card supplied from manual sheet supply trays to aligning rollers which conveys sheet vertically. When special sheet is conveyed, the sheet is inserted between the special sheet ribs to prevent skew. When ordinary sheet is conveyed, the sheet is passed above the upper surface of the special ribs so as to prevent generation of defective image caused by bending of sheet.

Abstract: An apparatus for continuously producing electric-welded steel pipes by continuously supplying coiled strips as connected to one another by welding, progressively forming the strip into a tubular shape and high-frequency welding the opposed edges of the strip to form a seam. To produce required small quantities of steel pipes having varying diameters and wall thicknesses, a group of roll assemblies is replaceable by another group within a short period of time. Groups of forming, welding or sizing rolls are mountable on a polygonal bed which is lockable in position after rotation. For replacement, the bed is rotated by a hydraulic motor to bring the desired group of rolls to the proper position quickly.
