A heavy metal element is added to a SiC single crystal (6) during the growing of the SiC single crystal (6) so that the addition density of the heavy metal element can become 1 × 1015cm-3 or more. The SiC single crystal (6) having this constitution hardly undergoes dislocation by the action of a thermal stress generated during the growth thereof. Therefore, when the SiC single crystal (6) is sliced to produce a wafer and a SiC layer is epitaxially grown on the wafer, dislocation rarely occurs. Due to this constitution, a SiC single crystal which is prevented from the occurrence of dislocation or multiplication can be produced.

In this SiC diode (20), the impurity concentration of a second semiconductor layer portion (25A) having a thickness of less than 100 nm (for example, 50 nm) changes from a third impurity concentration (for example, 1 × 1020 cm-3) to an acceptor density of 1 × 1019 cm-3, said third impurity concentration being different by one or more orders of magnitude from an acceptor density of 1 × 1019 cm-3 that is a second impurity concentration. A discontinuous growth surface, where the impurity concentration changes abruptly, is formed in the second semiconductor layer portion (25A). This discontinuous growth surface serves as a recombination promoting surface for promoting the recombination of carriers, enabling a switching loss to be reduced. In addition, the carrier injection efficiency into a drift layer (23) is maintained high as compared with the case in which a pn-junction interface is used as the discontinuous growth surface, thereby enabling a steady loss to be prevented from increasing. This provides a bipolar semiconductor device, the switching loss of which can be reduced and the steady loss of which can be prevented from increasing.

By covering the inner circumferential surface of an outer cylinder with a vapor film, thermal conductivity is reduced and the phenomenon of sudden temperature increases in the cylinder wall of the outer cylinder can be prevented, thereby preventing heat damage to the outer cylinder. Additionally, burner burnout, caused by insufficient cooling resulting from irregularities in cooling efficiency at the burner tip, is also prevented. A tip, which is positioned inside a two-stage entrained-flow bed coal gasification furnace, has a double-walled cylindrical structure with an outer cylinder and an inner cylinder, and is configured so that cooling water to cool the tip is supplied via the inside of the inner cylinder and, after cooling the tip, is returned to the base end via the space formed between the outer cylinder and the inner cylinder, and is additionally configured so that the flow path surface area of the space formed between the outer cylinder and the inner cylinder is less than the flow path surface area formed inside the inner cylinder, thus configured so that a swirling flow along guides formed on the outer circumferential surface of the inner cylinder, and a roughly linear flow in the lengthwise direction of the outer cylinder and the inner cylinder, are imparted to the cooling water that is returning to the base end via the space formed between the outer cylinder and the inner cylinder.
