Abstract: An electronic device includes a circuit board, an electronic element, multiple connection bumps, a preventive bump, and a sidefill. The electronic element is mounted on the circuit board. The connection bumps are connected to the electronic element. The preventive bump is provided between the connection bumps. The sidefill surrounds the electronic element.

Abstract: An optical module includes a board, a lens member, and first, second, and third bonding parts each bonding the board and the lens member. The lens member includes lenses which light from the light emitter enters or light enters the light receiver through. The first bonding part is positioned on a line passing through the center of each of the lenses. The second and third bonding parts are symmetrically positioned with respect to the line.

Abstract: An optical module includes a lens sheet having a plurality of lenses on an upper surface thereof, a substrate having at least one of a light emitting device and a light receiving device on an upper surface thereof, and an adhesive film bonding the upper surface of the lens sheet and a lower surface of the substrate, wherein the lens sheet has a plurality of protrusions on the upper surface thereof, and the substrate has through holes in which the protrusions are situated.

Abstract: An optical module includes a lens sheet having at least one lens on one surface thereof, a substrate having at least one of a light emitter or a light receiver on one surface thereof, and an adhesive film configured to bond the lens sheet to the substrate, wherein a protrusion is formed on the lens sheet so as to surround the lens.

Abstract: A lens sheet includes a base made of transparent resin, a lens part formed on the base and having a convex lens, and a protrusion formed around the lens and having a height lower than a height of the lens. A gap is provided between the lens and the protrusion.

Abstract: An optical module includes a lens sheet having at least one lens on one surface thereof, a substrate having at least one of a light emitter or a light receiver on one surface thereof, and an adhesive film configured to bond the lens sheet to the substrate, wherein a protrusion is formed on the lens sheet so as to surround the lens.

Abstract: X-ray penetration images picked up by an X-ray penetrating device are supplied to an image processor, and stored in a magnetic disk unit as radiographic image data. The radiographic image data are reproduced on a reproduced image display monitor installed in an examination room. The examination room further includes a fluoroscopic image display monitor for selectively displaying the fluoroscopic images and menus. The menus include functions to select radiographic image data for reproduction on the reproduced image display monitor and to select a display mode. The functions shown on the menus may be selected and instructed by operating a joystick. During a procedure of interventional radiology, an operator operates the joystick to select and instruct desired radiographic image data to be reproduced. A display mode for enlarging reproduced images may be selected as necessary.
