摘要:
A solar cell is constructed using a heterojunction formed by layering an n-type compound semiconductor followed by a p-type compound semiconductor on an insulator layer containing titanium oxide which has been formed on one side of a glass plate. The insulator layer can improve the photoelectric conversion efficiency of the solar cell by lowering the sheet resistance of the n-type semiconductor film which is used as the window material of the solar cell. In addition, light transmittance is improved.

A method for forming a CdTe film of good quality by an improved close-spaced sublimation process is disclosed. This method comprises: a step of applying a paste which contains material for CdTe semiconductor on a supporting member, thereby to form a coating film which contains the material for the semiconductor on the surface of the supporting member; a step of closely arranging the supporting member and a substrate on which a CdTe film is to be formed, to make the coating film to face the surface of the substrate; and a step of forming a CdTe film on the substrate, by heating the coating film and the substrate, and causing the material for the semiconductor in the coating film to evaporate.

An operation device includes: an operated body; an operation signal producing part that produces an operation signal based on an operation on the operated body; and a tactile information presenting part that presents tactile information through the operated body. The operation device may be applied to an electronic book device for flipping of pages.
摘要:
A pointing device that can move an object in a desired direction on a display screen includes a control unit that switches between a first mode and a second mode in accordance with the contents of the display on the display screen. In the first mode, the pointing device outputs information as to the location of the object within a pointing area. In the second mode, the pointing device divides the pointing area into a plurality of areas and outputs information as to the divided area in which the object is located.
摘要:
A signal transmission and reception device is disclosed that can be made compact and has wide-band band-pass characteristics. The signal transmission and reception device includes a first filtering unit that is composed of a distributed constant circuit and is capable of eliminating a first frequency component or a second frequency component. The second frequency is higher than the first frequency, and a second filtering unit that attenuates components of frequencies lower than the first frequency or components of frequencies higher than the second frequency.
