Abstract: A solar panel, above which a pointer mounted on a pointer shaft inserted in a through hole in a center portion of the solar panel moves, includes a plurality of solar cells arranged in a substantially circular shape, and these solar cells have been divisionally formed into a substantially spiral shape so that the pointer is positioned over two of the plurality of solar cells. Accordingly, the pointer can always be positioned over two of the plurality of solar cells, and therefore a decrease of light-receiving area due to the pointer can be distributed between the two solar cells. As a result, a decrease in the output current of the plurality of solar cells over which the pointer is positioned can be suppressed, and the output current of the entire plurality of solar cells can be improved.

Abstract: In a rotor manufacturing method of the present invention, firstly, a rectangular magnet element whose magnetic pole direction is recognizable is formed by a magnetic material being sintered while a magnetic field is being applied thereto, and subjected to a demagnetization process, and position regulating sections are formed on the magnet element symmetrically relative to the magnetic poles. Accordingly, a magnet can be easily formed. Secondly, the demagnetized magnets are individually transported without being attracted to each other. Accordingly, the direction of each magnetic pole of the demagnetized magnets can be aligned to one direction and successively arranged. Thirdly, when a gear section is to be formed on the magnet, it is positionally adjusted by the position regulating sections so as to have a fixed positional relationship relative to the magnetic poles of the demagnetized magnet. Accordingly, the gear section can be precisely formed relative to the magnetic poles.

Abstract: A solar panel of the present invention, above which pointers mounted on a pointer shaft inserted into a through hole provided at the center of the solar panel move, includes a center cell circularly formed around the through hole and a plurality of outer-circumferential cells formed around the outer periphery of the center cell in a manner to have substantially same light-receiving areas. The center cell is formed to have a light-receiving area larger than the light-receiving area of each outer-circumferential cell, taking into consideration a light-shielding area where the pointers overlap with the center cell. Therefore, even though the pointers always overlap with the center cell and part of the pointers overlaps with one of the plurality of outer-circumferential cells, the fluctuation of each light-receiving area of the center cell and the plurality of outer-circumferential cells due to this overlap can be minimized.
