Abstract: A stepping motor includes a rotor, a stator and three coils. The rotor is two-pole magnetized in a radius direction. The stator is provided with a rotor receiving section for receiving the rotor. The three coils are magnetically connected with the stator. At least one of the three coils is an integrated coil which is integrally formed with the stator by winding a coil around a part of the stator.

Abstract: Disclosed is a stepping motor including a rotor, a plurality of coils and a switching mechanism. The stepping motor simultaneously or sequentially applies driving pulses to the coils to rotate the rotor by a predetermined step angle, and while the driving pulses are being applied to part of the coils, the switching mechanism switches the rest of the coils other than the part of the coils driven by the driving pulses into a high impedance state.

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.

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.
