A system for stacking or arranging any asymmetric subject of manufacture having a distinguishable front end and a rear end such as a glove. More particularly, a stacking or arranging system and methods enabling bidirectional stacking or arranging one over the other for packing or like purposes of such asymmetric subject of manufacture having a distinguishable front end and a rear end such as a glove. The system for such bidirectional stacking or arranging basically involving a feeder conveyor unit having a pair of feeder conveyer (2,3) disposed below a manufacture process conveyer (1) which can be used for stacking different asymmetric packing elements/subjects such as gloves having distinguishing front and rear end over collecting member/shelf (10,12) in bidirectional manner. Optionally and advantageously, the proposed stacking apparatus includes a sensor driven oscillating means operatively connected with the feeder conveyer pair for driving the feeder conveyer in pendulum type motion and to facilitate the bidirectional stacking of the packing element over a collecting member/ shelf. The advancement is thus directed to provide for an automatized system for bidirectional stacking of asymmetric packing elements/subjects such as gloves to ensure optimized arrangement of the stocks for packing and the like and an even distribution of the weight of the stacked subjects such as when packed in a carton and the like.

In a battery voltage adjusting circuit, when an output voltage for a generator terminal output by a single phase alternating current generator has a negative polarity, a control circuit turns a first switch element on when a comparative value, which is an effective value or an average value for a lamp voltage for a lamp terminal, is less than a target voltage. Meanwhile, when the output voltage has a positive polarity, the control circuit turns a third switch element on when the comparative value is less than a threshold voltage, which is lower than the target voltage, and turns on a second switch element when the battery voltage for a battery is less than a prescribed voltage.

A drive control method whereby the position of the rotational angle of an engine after normal rotational driving is determined on the basis of: information regarding whether the rotational angle of the engine has passed a first top dead center due to normal rotational movement when the engine is rotated normally with a predetermined reference torque; the amount of normal rotational movement by which the engine has moved in the normal rotational direction; and the amount of reverse rotational movement by which the engine has moved in the reverse rotational direction.

A power generation control method determines whether each peak of the reciprocal of the rotation speed measured in a plurality of consecutive cycles of a 4-stroke engine is equal to or smaller than a first threshold and equal to or greater than a second threshold. If the first peak of the reciprocal of the rotation speed measured in the first cycle following the plurality of consecutive cycles is not equal to or smaller than the second threshold, it is determined whether the first peak is equal to or greater than a third threshold which is higher than the first threshold. If the second peak of the reciprocal of the rotation speed measured in a second cycle after the first cycle is equal to or smaller than a fourth threshold, the target voltage for generating power by a generator the rotary shaft of which is connected to the crankshaft of the 4-stroke engine is switched from the voltage in the normal state to a voltage during acceleration which is lower than the voltage in the normal state.
