Title: Charger
Inventor: SATO SHOJIRO
IPC: H02J7/10
Filed: 1993-01-26
Abstract: PURPOSE:To detect the charged status of a secondary battery arbitrarily and accurately by a method wherein a connection between the secondary battery and a charger is opened with a predetermined period. CONSTITUTION:A charging current cut off switch SW which is connected to a secondary battery B is turned on and off with a certain or arbitrary period by a signal in accordance with a predetermined period from a charge control circuit 10 to put a charging current supplied to the secondary battery B into an open state with a certain or arbitrary period. During the open period, i.e., while a connection between a charger 1 and the secondary battery B is opened, a differential voltage which is calculated in accordance with a voltage obtained from the minus terminal of the secondary battery B (i.e., a voltage of a point B (P)) is detected by a voltage detecting circuit 9 to detect whether the secondary battery B is fully charged or not. By this constitution, the charged status of the secondary battery can be detected arbitrarily and accurately.

Title: Constant current circuit
Inventor: ASAMI TAKAO
IPC: H03F3/343
Filed: 1987-01-22
Abstract: PURPOSE:To obtain a stable constant current output by feeding negatively a partial output of a current mirror circuit back to a reference current source so that the Early's effect is compensated and the dependence on the power supply voltage is removed for the output current. CONSTITUTION:A transistor TRQ5 different from a TRQ4 is connected to a TRQ3 and a current mirror circuit is constituted out only of a set of the TRQ3 and Q4 but a set of the TRQ3 and Q5. Then the output current I0' of the TRQ5 is fed back to the emitter of a TRQ2. The TRQ3-5 are set laterally in a monolithic IC and therefore have the similar characteristics. When the power supply voltage V<+> has variance, the output currents I0 and I0' of the TRQ4 and Q5 are fluctuated with the I0/I0' ratio kept constant. Thus the value proportional to the level of the Earl's effect can be negatively fed back to a reference current source (TRQ2). In such a way, it is possible to compensate the Early's effect of the current I0 and to remove the dependence on the power supply voltage for the output current. Then a stable current output is obtained.
