Abstract: A charge control means (10) provided for a battery charging apparatus (1) conducts protection control for a battery pack (2) by transmitting a signal to an output control switch (14) for turning off an output when a rise rate of the temperature of the battery pack (2) detected based on information from a temperature detection terminal (8) is equal to or more than a predetermined value, or a rise rate of the voltage of the battery pack (2) detected based on information from a voltage detection terminal (9) is equal to or less than a predetermined value.

Abstract: A manufacturer supplies a customer with software for designing a product indication (S1, S11), and then, the customer creates a product indication draft by using the software (S2, S12). The manufacturer conducts a correction to the product indication draft and the like by exchanging information over a communication network (5) (S3, S13), produces a product on which the determined product indication (2) is printed (S6, S16) when the customer approves a sample on which the product indication (2) is printed (S5, S15), and supplies the customer with the products (S7, S17).
