A control circuit is provided in which two power sources can be efficiently switched, for a power supply apparatus provided with a step down switching regulator and a linear regulator. A PWM controller generates a pulse width modulation signal with which a duty ratio is controlled so that output voltage of the switching regulator approaches a predetermined reference voltage. A compulsory OFF circuit monitors a switching voltage, and when a first threshold voltage is exceeded, switches a synchronous rectifier transistor OFF. A minimum ON time setting circuit limits the duty ratio of the pulse width modulation signal, so that ON time of the switching transistor is longer than a predetermined minimum value. A selector circuit monitors an error voltage, and when a predetermined state continues for a predetermined first period, puts the linear regulator in an operating state, and the step down switching regulator in a halt state.

In a battery cooling device for cooling a battery with cooling air from a cooling unit, such as a cooling fan, the cooling fan is not to be driven more than necessary. A cooling air flow control unit calculates a battery temperature change rate indicating an amount of change in battery temperature over a predetermined time based on the battery temperature, and if the calculated battery temperature change rate satisfies a predetermined suppression control condition, the cooling air flow of the cooling fan is suppressed regardless of whether or not the battery temperature is at or below a reference temperature.

A camera comprises an angular velocity sensor for detecting camera-shake. The angular velocity sensor takes a certain time to be stabilized after its operation is started. When correction of camera-shake is required during the certain period, it is displayed that correction of camera-shake is not possible. As a result, a photographer using the camera with the camera-shake detection sensor refrains from photographing when correction of camera-shake is not possible.

Physical index of the measured such as pulse frequency is measured by the pulse instrument. A determination result is given based on synthetic evaluation of the three types of index, so that the determination result is more accurate and objective in comparison with that given only from morphological index, and error determination of driver's fatigue degree is prevented.

A hub for a bicycle includes a shaft, a hub body, a ratchet wheel, a damper, a drive seat, and a plurality of pawl members. Thus, when the drive seat is rotatable backward, the locking detent of each of the pawl members is detached from the oneway ratchet teeth of the ratchet wheel constantly, so that each of the pawl members will not touch the ratchet wheel to prevent from incurring a noise. In addition, when the drive seat is rotatable backward, the hub body is separated from the drive seat, and rotation of the hub body will not drive the drive seat and the pedal to prevent the pedal from being driven when the hub body is rotated backward.
