Abstract: A battery pack (1) is connected to an external device (9) and to a power supply circuit (10) for the external device (9), and it energizes the external device (9) or is charged by the power supply circuit (10). An analog circuit (12) and a microcomputer (11) inside the battery pack (1) detect an ON/OFF state of the external device (9) and execute control in such a manner as to effect charging by the balance of power obtained by subtracting the maximum power consumption of the external device (9) from the total capacity of the power supply circuit (10) under the ON state and to effect charging by full use of the supply power from the power supply circuit (10) under the OFF state. This charge/discharge control is executed when the microcomputer (11) makes ON/OFF control of a charging switch (S1), a discharging switch (S2) and a switch (S4).

Abstract: The battery pack (1) is connected to an external device (9) and to a power supply circuit (10) for the external device (9), and it energizes the external device (9) or is charged by the power supply circuit (10). Communication is made between a microcomputer (11) inside the battery pack (1) and the external device (9) through terminals (8) and at least information representing a present residual charge of a battery (4) is transmitted from the microcomputer (11) to the external device (9). This residual charge is calculated by the microcomputer (11) using the current, voltage, internal resistance and temperature of the battery (4). In this way, the residual charge can be obtained with a high level of accuracy on the side of the external device (9).

Abstract: The apparatus, suitable for editing video tapes, includes a video playback unit (38), a video recording unit (39) having recording circuitry (50) for recording a video output signal from the video playback unit (38) as well as reproducing circuitry (51) for reproducing a video signal, and a sub-picture signal former (55) responsive to a video signal supplied thereto for providing a sub-picture signal to be displayed as a sub-picture insert of a main picture on a monitor (13). A switch (63) couples either the video output from the video playback unit (38) or the video output from the reproducing circuitry (51) included in the video recording unit (39) to the sub-picture signal former (55). The video signal which is not coupled to the sub-picture signal former (55) constitutes the main picture signal, and the sub-picture and main picture signals are combined in a combining circuit (53) to form a display signal which, when displayed, produces a main picture with a sub-picture insert. A common housing (4) may contain the video playback and video recording units (38, 39), the sub-picture signal former (55), the switch (63) and the sub-picture/main picture signal combining circuit (53).

Abstract: A battery pack having a detection recess formed along a center line of a bottom surface arranged such that the detection recess is engaged with a convexed portion of a battery charger. Therefore, whether or not the battery pack is properly attached to the battery charger can easily be detected by the inclination of the battery pack about the center line. Further, a battery pack is arranged such that an aperture is formed on an outer surface of the battery pack and an output terminal is inwardly disposed on the aperture. Therefore, damage to the batteries in the battery pack caused by a short-circuit resulting from products made of conductive metal material such as a key ring, necklace, or chain contacting both of the output terminals, as occurs when terminals are disposed on the outer surface of the battery pack, can be prevented. Furthermore, the battery pack includes apertures with output terminals disposed therein for discharging dust or the like away from the terminals into the interior of the casing or out of the casing through a hole. Therefore, the accumulation of dust or the like within the apertures and upon the output terminals is prevented.

Abstract: PROBLEM TO BE SOLVED: To provide a nonaqueous electrolyte secondary battery preventing internal short-circuiting completely. SOLUTION: The length of a longitudinal direction of a positive electrode active material layer 22 is formed longer than that of a longitudinal direction of a negative electrode active material layer 32. There exists, therefore, no place where an exposed portion of a positive electrode collector 21 and the negative electrode active material layer 32 face, and where a large joule heat is generated when the short-circuiting occurs. The security is thereby significantly improved at the time of dendrite short-circuit by incoming foreign substances or the like, or short-circuit under usual service conditions by internal pressure variations due to expansion and contraction of electrodes during charge and discharge.

Abstract: PROBLEM TO BE SOLVED: To send various information to an electronic machine by means of a low-speed-processing microcomputer with saved power. SOLUTION: A CPU 31 collects detection data such as terminal voltage and discharging current of a thermistor 62 and a battery through respective interfaces 38, 37 and 36 every ten seconds, calculates a residual capacity or a total capacity of the battery, stores the results and the collected data as transmission data in a RAM 33, and sends the stored transmission data from a communication interface 39 to the electronic machine not shown at one-second intervals. Since the CPU 31 only transmits the data independently from an operation of a CPU in the electronic machine, an operation clock of the CPU 31 can be remarkably reduced, and also its power consumption can be remarkably reduced.
