    摘要: A process for producing a semiconductor substrate is provided which comprises a first step of anodizing a surface of a first substrate to form a porous layer on the surface, a second step of simultaneously forming a semiconductor layer on the surface of the porous layer and a semiconductor layer on a surface of the first substrate on its side opposite to the porous layer side, a third step of bonding the surface of the semiconductor layer formed on the surface of the porous layer to a surface of a second substrate, and a fourth step of separating the first substrate and the second substrate at the part of the porous layer to transfer to the second substrate the semiconductor layer formed on the surface of the porous layer, thereby providing the semiconductor layer on the surface of the second substrate. This makes it possible to produce semiconductor substrates at a low cost while making good use of expensive substrate materials.

    摘要: A solar cell module comprises a plurality of unit cells connected in series, each of the unit cells comprising in this order an electrode, a first semiconductor layer having a first conductivity type and a second semiconductor layer having a second conductivity type. The electrode has a region not covered with the first semiconductor layer. The second semiconductor layer has a main region and a subregion which are separated by a groove. The main region of the second semiconductor layer in one unit cell is electrically connected to the region of the electrode not covered with the first semiconductor layer in another unit cell adjacent to the one unit cell. The region of the electrode not covered with the first semiconductor layer in the one unit cell is electrically connected to the subregion of the second semiconductor layer in the another unit cell. With this structure, it is possible to simplify the formation of a bypass diode and therefore provide a solar cell module with high reliability at a low cost.

    摘要: An earth removing apparatus for a shield tunneling machine comprising a tubular casing having an excavated earth inlet at one end and a closable outlet for excavated earth at the other end, and a double-shaft screw conveyor rotatably supported by the casing at two portions. The screw conveyor is supported on the casing in the vicinity of its earth inlet by an annular member fitted in an annular recess in the casing, with a bearing provided between the annular member and the casing. Since the forward end of the screw conveyor need not be supported at the center of rotation of the cutter head of the tunneling machine, the apparatus can be designed with greater freedom and is free of objections in its mechanical structure.
