A stepping motor control circuit includes: a rotation detection unit that detects a induced signal exceeding a predetermined reference threshold voltage which is generated by a stepping motor in a detection section divided into at least three sections, and detects a rotation state on the basis of a pattern indicating whether the induced signal exceeding a reference threshold voltage is detected in each of the sections; and a control unit that selects a main drive pulse depending on the rotation state detected by the rotation detection unit from a plurality of main drive pulses which are different from each other in energy, and drives the stepping motor. When the induced signal exceeding a reference threshold voltage is not detected in an initial section, the rotation detection unit detects the induced signal by shifting an end position of at least one section other than the initial section to a rear side by a predetermined amount.

In a method of manufacturing an electroforming mold, a first photoresist layer is formed on an upper surface of a bottom conductive film of a substrate, and the first photoresist layer is divided into a first soluble portion and a first insoluble portion. A conductive material is thermally deposited on an upper surface of the first photoresist layer within a predetermined temperature range, to thereby form an intermediate conductive film. An intermediate conductive film is patterned. A second photoresist layer is formed on an exposed upper surface of the first photoresist layer after the intermediate conductive film is removed, and on an upper surface of the intermediate conductive film remaining after patterning. The second photoresist layer is divided into a second soluble portion and a second insoluble portion. Next, the first and second photoresist layers are developed, and the first and second soluble portions are removed.

An electronic timepiece is operated with a power-supply voltage from a secondary battery charged with a voltage from a solar panel. An oscillation circuit generates and supplies a clock signal to a CPU when the voltage charged to the battery is lower than a first voltage. A reset circuit resets the CPU when the voltage charged to the battery does not exceed a second voltage higher than the first voltage, and cancels the reset of the CPU when the voltage charged to the second battery exceeds the second voltage. The CPU starts an operation when the voltage charged to the secondary battery exceeds the second voltage and the reset is cancelled, and performs a time-of-day display on a display unit when the voltage charged to the secondary battery is equal to or higher than a third voltage higher than the second voltage.
A control circuit selects a drive pulse group corresponding to the detected voltage of a power cell from among plural drive pulse groups each including plural types of main drive pulses, and selects a drive pulse according to the detected condition of rotation of a stepping motor from among main drive pulses included in the selected drive pulse group or a correction drive pulse having larger energy than the main drive pulses. When the control circuit selects a main drive pulse initially by selecting the drive pulse group, the control circuit selects the main drive pulse having the largest energy in the selected drive pulse group. A drive pulse group selection circuit drives the stepping motor by the main drive pulse in the drive pulse group selected by the control circuit or the correction drive pulse via a main drive pulse output circuit and a correction drive pulse output circuit.
