IPC: H03G3/12
Filed: 1998-12-01
Abstract: PROBLEM TO BE SOLVED: To attain low power consumption, miniaturization and noise reduction and to realize a signal selection function without causing characteristic deterioration. SOLUTION: A differential amplifier circuit is formed by turning on switch means 12, 20 and turning off switch means 26, 32 consisting of MOS transistors(TRs), differential signals fed to 1st and 2nd input terminals 6, 14 are selectively converted into a single signal, which is outputted. On the other hand, when the switch means 12, 20 are turned off and the switch means 26, 32 are turned on, a single signal from a 3rd input terminal 22 is selectively amplified and outputted. When all of the switch means are turned on, both the signals are summed and the sum signal is outputted. Furthermore, the amplification factor can be changed by 1st and 2nd variable resistors 34, 36 to adjust the signal level. The functions above are realized by using one operational amplifier 4 only and the task above an be attained through the selection of the signals by the switch means.

Title: Battery container for electric automobile
Inventor: ONO MASAO
IPC: H01M50/209
Filed: 1991-12-02
Abstract: PURPOSE:To reduce the weight by arranging a position specifying means for deforming space dimension between a front wall internal surface of a container and a front surface of a battery in a direction contracted, and reducing strength of the battery container against a shock in the case of large deceleration. CONSTITUTION:A plate 21, which can be destructed by a predetermined deceleration load applied to a row of battery 5, is embedded in every other row of the battery (for instance, odd row) in a front wall of a container 6. When excessive deceleration acts on a vehicle, action of tending to forwardly move is applied to the battery row. Even row battery is retained before and after it by front/rear walls of the container 6 and not moved. On the other hand, the battery of odd row is moved to the front because the plate 21 is broken through by a spacer 22, to disconnect the fellow contact plates 18. In this way, a shock of colliding against the front wall of the container 6 is absorbed by destruction of the plate 21 in the case of applying large deceleration to the vehicle, and also relaxing a shock by inertia force of the battery 5 by moving the battery row.
