Abstract: The problem addressed by the present invention is providing a technique for fabricating, by a method simpler than conventional methods, a silicon substrate that is effective for light trapping, one surface of which has a textured structure and the other surface of which has higher reflectivity than the surface having the textured structure. The fabrication method for this semiconductor substrate comprises: a sandblasting step in which a first surface of a silicon substrate in an as-sliced state, fabricated by slicing a silicon ingot, is surface treated by sandblasting and, after the sandblasting step, a step for carrying out surface treatment using an etching solution that contains either or both of hydrofluoric acid and nitric acid on the silicon substrate.

Abstract: A rotating seat for a vehicle includes a seat surface tilt angle varying mechanism, a seat surface rotating mechanism and a single drive source. The seat surface tilt angle varying mechanism is configured and arranged to vary a tilt angle of a seat surface of a seat body. The seat surface rotating mechanism is configured and arranged to rotate the seat surface. The drive source is configured and arranged to drive the seat surface tilt angle varying mechanism and the seat surface rotating mechanism.

Abstract: A power source of a LAN terminal at a home such as home server is turned on from the outside the home via the Internet. A home gateway apparatus receives such a start request by proxy and transmits a start instruction packet to corresponding equipment on the home LAN. Although there is a case where the protocols of an external network and the home LAN are different from each other, the home gateway apparatus performs a protocol conversion process for assimilating discrepancy between the protocols. Moreover, on the home LAN, the start instruction packet to the corresponding equipment maybe issued by utilizing a magic packet technique.

Abstract: A plasma display panel which uses a porous metal plate having a thickness of 0.01 to 1.0 mm as a spacer and/or a discharge diaphragm, and has an insulating layer that electrically insulates said porous metal plate from the discharge electrodes, and a method for the production of the same.

Abstract: A supporting mechanism for a fixed detection section in a detection device comprises the fixed detection section and a rotary detection section. The mechanism comprises a plate spring and a supporting plate. The plate spring is mounted on a fixed housing of a drive motor in spaced relation thereto, and has at least in part an elastic portion whose resilient force direction along an axial direction of the rotary shaft. The supporting plate of a ring shape has a plurality of elongated apertures formed therein along a concentric line, and is mounted on the plate spring in spaced relation thereto. The fixed detection section is fixedly connected with screws through the elongated apertures to the supporting plate.
