Abstract: According to one embodiment, a medical image diagnostic apparatus includes a storage memory, processing circuitry, and a display. The storage memory stores data of a plurality of FFR distribution maps constituting a time series regarding a coronary artery, and data of a plurality of morphological images corresponding to the time series. The processing circuitry converts the plurality of FFR distribution maps into a plurality of corresponding color maps, respectively. The display displays a plurality of superposed images obtained by superposing the plurality of color maps and the plurality of morphological images respectively corresponding in phase to the plurality of color maps. The display restricts display targets for the plurality of color maps based on the plurality of FFR distribution maps or the plurality of morphological images.

Abstract: A surface-mountable glass-sealed light-emitting diode is provided. It has high reliability and high external quantum efficiency, and can achieve a low-cost components-implemented board. An LED bare chip (1) has opposite surfaces, which are provided with electrodes (2) for supplying power from external. A pair of dumet wires (3) are separately connected to the respective electrodes (2) sandwiching the LED bare chip (1) therebetween. The LED bare chip (1), the electrodes (2) and parts of the dumet wires (3) are integrally glass-sealed (4). A pair of metallic disc plates (6) have holes (5) formed through the center. They are secured on both sides of the glass seal (4) and solder-plated, allowing the pair of dumet wires (3) projected from the glass seal to pass through the holes (5).

Abstract: A semiconductor light-emitting device can serve as a high-brightness light source with less tone variation. A reflective frame having a conical recess can be provided on a substrate. An LED chip can be mounted on the bottom in the reflective frame. A wavelength converter material is preferably filled in the recess to seal the LED chip. The wavelength converter material can include a fluorescent material and a 20-80 wt. % diffuser mixed in an optically transmissive resin.

Abstract: A flat lighting device designed to be free from accidental breakage of the leading-in wires for the luminous body comprised therein if they are subjected to vibration in use to consequently enhance the overall reliability of the flat lighting device. Such a flat lighting device comprises a panel-shaped transparent substrate, a light source holding unit fitted to an end face of the substrate and a tubular luminous body fitted to said light source holding unit and is characterized in that said light source holding unit is made of a conductive material and has a substantially U-shaped cross section such that it engages said end face at the open side thereof and that one of the leading-in wires of said luminous body is connected to said light source holding unit to form thereon a power feed section for the luminous body.

Abstract: A transformer core assembly in a transformer comprises a coil having a primary winding and a secondary winding which are successively wound about a hollow coil bobbin, in division, with respect to a longitudinal direction of the hollow coil bobbin, and a pair of E-type cores in which central core sections of respective three core sections extending in parallel relation to each other are inserted respectively from both ends of the coil bobbin into a hollow section therewithin. The core sections of one of the pair of E-type cores have lengths thereof which are formed shorter than lengths of the core sections of the other E-type core. When the central core sections are inserted respectively into the hollow section within the coil bobbin, so-called core gaps defined such that the core sections have respective forward ends thereof which are abutted against each other are located within an area corresponding to the primary winding of the coil bobbin.
