Abstract: A sheet conveying device includes a sheet stacker, an air blower, and a guide. The sheet stacker stacks sheets. The air blower blows air to the sheets. The guide faces an uppermost sheet on the sheet stacker. A set height of a contact portion of the guide to contact the uppermost sheet is changeable.

Abstract: A magnetic sensor includes a ceramic substrate, a GMR layer, and an undercoat layer. The ceramic substrate includes a substrate body and a glazing layer. The substrate body contains a ceramic as a material thereof. The glazing layer is formed on a surface of the substrate body. The GMR layer has a multilayer structure of a plurality of magnetic layers and a plurality of non-magnetic layers. The undercoat layer is formed between the glazing layer and the GMR layer. The undercoat layer contains a BCC solid solution.

Abstract: A circuit module is provided that is configured to allow a shield member to be securely mounted to a board. The circuit module includes a board with a mounting surface on which an electronic component is mounted and a shield member that is mounted to the board. The shield member includes a shield frame having a frame portion that is solder-joined to the mounting surface and a shield cover having a top surface portion and a side portion that is attached to the frame portion of the shield frame. Furthermore, an L-shaped slit is formed at a predetermined corner among four corners of the top surface portion of the shield cover so as to extend along two sides forming the predetermined corner.
