    摘要: A protection element is provided which is capable of stably retaining a flux on a soluble conductor at a predetermined position, enabling a speedy and precise blowout of the soluble conductor in the event of an abnormality. This protection element includes: a soluble conductor 13 which is disposed on an insulation baseboard 11 and is connected to a power supply path of a device targeted to be protected, to cause a blowout by means of a predetermined abnormal electric power; a flux 19 which is coated onto a surface of the soluble conductor 13; and an insulation cover 14 which is mounted on the baseboard 11 with the soluble conductor 13 being covered therewith. In addition, the protection element is provided with a protrusive stripe portion 20 which is formed on an interior face of the insulation cover 14 in opposite to the soluble conductor 13 and in which a stepped portion 20a for retaining the flux 19 is formed at a predetermined position while in contact with the flux 19. The soluble conductor 13 has a hole portion 13a at which the flux 19 is retained.

    摘要: A thermionic converter for converting thermal energy to electrical energy includes an emitter and a collector. The emitter emits thermionic electrons upon receipt of heat from a heat source. The emitter is made of a first semiconductor material to which a first semiconductor impurity is doped with a first concentration. The collector is spaced and opposite to the emitter to receive the thermionic electrons emitted from the emitter so that the thermal energy is converted to electrical energy. The collector is made of a second semiconductor material to which a second semiconductor impurity is doped with a second concentration less than the first concentration.
