Abstract: A semiconductor substrate of a reverse conducting IGBT includes a collector layer in contact with a collector electrode, within an IGBT region and a boundary region. The collector layer has a first collector layer provided in the IGBT region and a second collector layer provided in the boundary region. The second collector layer has a lower impurity concentration than the first collector layer.

Abstract: A semiconductor substrate of a reverse conducting IGBT has a first conductivity type buffer layer disposed between a collector layer and a drift layer. The buffer layer has a first buffer layer provided in the IGBT region and a second buffer layer provided in the boundary region. The peak concentration of the first conductivity type impurity in the second buffer layer is higher than that in the first buffer layer.

Abstract: A reverse-conducting insulated gate bipolar transistor (IGBT) includes a first conductivity type boundary layer of a first conductivity type and a second conductivity type boundary layer of a second conductivity type disposed in a boundary region located between an IGBT region and a diode region. The first conductivity type boundary layer is disposed below a drift layer, and is in contact with a lower electrode. The second conductivity type boundary layer is disposed between the first conductivity type boundary layer and the drift layer.

Abstract: A culture apparatus includes an inner box for housing a culture, an outer box surrounding the inner box, and a first vibration prevention mechanism that is disposed between the inner box and the outer box, and is configured to prevent the inner box from vibrating due to the vibration of the outer box.

Abstract: Disclosed is a candy wherein loss of a soft component contained therein is minimized, allowing the benefits of the soft component to be enjoyed, and a feeling of roughness in the mouth is reduced. Also disclosed is a method for manufacturing said candy. The disclosed candy (10) is provided with: a first region (20) containing a dispersion comprising a liquid dispersoid and an oil-based dispersion medium; and a second region (30) that at least partially encloses the first region (20) and comprises a hard candy composition that has been hardened. The disclosed method for manufacturing the candy comprises a procedure wherein the dispersion, which comprises the liquid dispersoid and the oil-based dispersion medium, is positioned in a melted hard candy composition and then said melted composition is hardened.

Abstract: The present invention provides a chewing gum that has a superior balance in flavor and texture as a whole while maintaining characteristics of chewing gum and can be expected to lower a manufacturing cost, and a method for manufacturing the same. A chewing gum of the present invention is manufactured by covering chocolate with a covering component containing a gum base so as to migrate oil contained in the chocolate into the covering component so that the chewing gum comprises a central part containing a chocolate-derived component and a covering part that covers the central part and contains the gum base and the oil.
