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 is provided on a visible side of a display panel and includes a transmissive area, a power generator and an anti-reflector. The transmissive area transmits light. The power generator generates electric power from light. The anti-reflector is provided on a display-panel-facing surface of the power generator to prevent reflection of light on the power generator. The display-panel-facing surface of the power generator faces the display panel. The light, the reflection of which is prevented by the anti-reflector, is among light having passed through the transmissive area and been reflected by the display panel.

Abstract: Disclosed is a solar panel being divided into a plurality of cells and including: a light transmissive power generation region which is a central region in a diameter direction of a ring-shaped member and in which extending thin line power generators are arranged in parallel in a direction substantially orthogonal to the extending direction; and a periphery power generation region which is a periphery region of the light transmissive power generation region and in which a part of the cells is arranged along a circumferential direction. The cells include a composite cell including at least a part of the periphery power generation region and at least a part of the light transmissive power generation region. A first cell and a second cell different from the first cell are respectively arranged on one end side and on the other end side in the diameter direction of the ring-shaped member.

Abstract: A rotation control apparatus for a stepping motor includes a motor control unit including a function of supplying to a coil a first pulse for rotating a rotor, a function of supplying to the coil a second pulse that is shorter than the first pulse and has the opposite polarity from the first pulse, and a function of supplying to the coil a third pulse that is shorter than the first pulse and has the same polarity as the first pulse; and a determination unit that determines whether or not the rotor has been rotated by the first pulse on the basis of a current that flows in the coil in response to the third pulse.

Abstract: A motor drive device includes a driver unit configured to be connected to a stepping motor, and a controller connected to the driver unit. The controller causes the driver unit to output a drive pulse to the stepping motor for causing the stepping motor to rotate stepwise in a prescribed rotation direction. The controller detects, through the driver unit, a current induced by a counter-electromotive force generated in the stepping motor in response to the drive pulse. The controller causes the driver unit to apply a counter pulse having the same electrical polarity as the drive pulse to the stepping motor so as to suppress an amount of the current induced by the counter-electromotive force when the stepping motor is not rotating in response to the drive pulse so that the amount of the induced current detectably differs between when the stepping motor is rotating and not rotating.

Abstract: A solar panel of the present invention, 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: A solar panel of the present invention includes a plurality of solar cells arranged in a substantially circular shape, and a plurality of connection sections which are provided near a center portion where the plurality of solar cells are all close to each other, and electrically connect the plurality of solar cells. Therefore, the plurality of connection sections can be centrally placed near the center portion where the plurality of solar cells are all close to each other. As a result, a decrease in the light-receiving area due to the plurality of connection sections can be reduced, and fluctuations in the light-receiving area due to pointers moving over the solar cells can be reduced.
