Title: Method for charging a plurality of lithium ion batteries
Inventor: MORITA HIDEYO
IPC: H02J7/02
Filed: 1995-04-28
Abstract: PURPOSE: To charge a plurality of lithium ion batteries in a short time without increasing the output current of a battery charger. CONSTITUTION: When the charging mode of either one of lithium ion batteries which are charged with constant currents first is switched to a constant-voltage charging mode, the charging current gradually decreases. The other lithium ion battery is simultaneously precharged with a charging current corresponding to the decreased amount of the decreasing charging current. The output current of a battery charger is prevented from increasing by controlling the sum of the charging current which charges the main lithium ion battery to the constant voltage and the charging current which precharges the other battery to nearly the same value. In addition, the residual capacity of the lithium ion battery to be charged first is detected before starting the charging so as to minimize the charging time of the battery.  In addition, the other lithium ion battery is precharged while the main battery is charged to a constant voltage for a fixed period of time after the charging mode of the main battery is switched to the constant-voltage charging mode from the constant-current charging mode and, thereafter, the other lithium ion battery is charged with a constant current.

Title: Frame synchronism settlement device and method
Inventor: OBUCHI KAZUCHIKA
IPC: H04J3/06
Filed: 1995-04-28
Abstract: PURPOSE: To shorten the synchronism settlement time and also to reduce the probability of wrong synchronism for a frame synchronism settlement device/ method which is placed at the reception side and settles the frame synchronism by receiving the digital transmission signal where a synchronizing word consisting of plural bits is periodically inserted. CONSTITUTION: A comparison means 3 compares a reception signal 1 in parallel with a synchronizing word 2 and outputs the non-coincident frequency in every bit. A preparatory decision means 4 outputs a preparatory decision signal to an estimation means 5 when the number of non-coincident bits is smaller than the 1st prescribed value. The means 5 estimates the position of the signal where a synchronizing word should be inserted in the next frame of the signal 1 in response to the input of the preparatory decision signal. A decision means 6 checks the number of non-coincident bits outputted from the means 3 when the position of the signal 1 estimated by the means 5 is inputted. Then the means 6 decides the settlement of frame synchronism when the number of non- coincident bits is smaller than the 2nd prescribed value.

Filed: 1982-06-18
Abstract: PURPOSE:To shorten the time for extinguishing fire by a method wherein a blower motor is driven intensely to put out the residual small flames in case of extinguishing a fallen down burner. CONSTITUTION:When a burner falls down to actuate a shock-proof automatic fire extinguisher 27 transferring a transfer contact 27a from (g-h) to (g-i), the power supply for a solenoid 6 is stopped to release a bar 4 for fire extinguishing operation. At the same time, a relay 39 is driven to transfer a transfer contact 39a from (j-k) to (j-l) normally transferring an operation switch 30 from (a-c) to (a-b) likewise in case of fire extinguishing operation. Therefore the ''INTENSE'' terminal of a blower motor 17a is supplied with power through the intermediary of a closed temperature switch 26, the transfer contact (j-l) of the relay 39 and the transfer contact (m-n) of a relay 42a to put out the residual small flames in the burning unit by blast. When the temperature of the burning unit declines to open the temperature switch 26, the power supplied for the blower motor 17a is stopped. Through these procedures, the small flames in case of fallen down burner may be put out improving the safety of the burner remarkably.
