摘要： In a pre-replacement process, a replacement battery module is provided with a memory effect before being dispatched, by performing at least one of the process of performing a cyclic charge/discharge operation on the replacement battery module while limiting the width of SOC change to an intermediate range, and the process of setting an initial SOC and then letting the replacement battery module stand for a predetermined time in an environment of temperature above normal temperature. This pre-replacement process substantially eliminates the difference between the voltage characteristic of the replacement battery module yet to be used and the voltage characteristic of a battery module having a history of use, thereby achieving a uniform voltage characteristic of a battery pack as a whole.

摘要： A power supply is provided, which is capable of stabilizing a generated output of the fuel cell using neither a voltage nor a current outputted from the fuel cell as a negative feedback signal. The power supply includes a fuel cell 110, a DC-DC converter 120 that adjusts a voltage outputted from the fuel cell 110 according to a PWM signal and then outputs the voltage to a load device 200, a switching controller 130 that generates the PWM signal and outputs this signal to the DC-DC converter 120, a voltmeter 140 that measures a voltage Vout outputted from the DC-DC converter 120, and a rechargeable battery 150 connected to the load device 200 in parallel. The DC-DC converter 120 calculates a duty ratio of the PWM signal by performing a specific computation using the voltage Vout and a target fuel cell voltage Vt.

摘要： A stator coil to be wound in and around a stator is manufactured. An insulating-coating conducting wire is bent to alternately provide the wire with slot-held conductor sections held in slots of the stator and a coil-end conductor section mutually connecting the slot-held conductor sections outside the slots. The coil-end conductor section is deployed outside the stator in the circumferential direction thereof. In manufacturing the stator coil, three or more pairs of molds are located along a portion of the wire in its longitudinal direction at predetermined intervals. The coil-end conductor section is formed by moving the molds along a direction allowing paired molds of each mold to come closer to each other, and the slot-held conductor sections is formed by moving the molds, in parallel, in both a direction perpendicular to the longitudinal direction and the longitudinal direction thereof.

摘要： A gear is manufactured in a half blanking stage, a punching stage and a separating stage. In the half blanking stage, half blanking is performed for a columnar portion of a metal sheet. A part of an outer circumferential surface of the blank is disconnected from the other portion of the sheet, while the other part of the outer circumferential surface of the blank is connected with the other portion of the sheet. In the punching stage, an inner portion of the blank is punched in a punching direction to form teeth on an inner circumferential surface of the blank. In the separating stage, the blank is separated from the other portion of the sheet as a gear toward a separation direction opposite to the punching direction by disconnecting the other part of the outer circumferential surface of the blank from the other portion of the sheet.
