    • An automatic seat positioning device for a vehicle driver's seat wherein a reversible motor is engaged with one of electromagnetic clutches and rotates so that an associated seat member actuating mechanism moves one of the seat members to a desired position for a specific driver from an initial position upto a maximum movable end. In such an automatic seat positioning device of the construction described above, a seat position detector corresponding to the seat member for detecting that the seat member arrives at a specific position at which the detector is located and a preset control circuit for presetting a counter, which indicates the set position of the seat member by counting the number of rotations of the motor, to a value corresponding to the number of rotations of the motor by which the seat member is moved from an initial starting position to the specific position are provided so that an indication error of the counter can be canceled due to slips which occur whenever the motor is repetitively started and stopped, engaged with the electromagnetic clutch. In addition, the automatic seat positioning device stores the positional data of the seat member set at the desired position from the counted value of the counter in a memory provided therewithin in order to return the current set position of the seat member to an originally set position on a basis of the stored data. In this case, a memory correction circuit is provided which corrects an erroneous stored data to an accurate value corresponding to the actual position in response to the presetting of the counter according to the number of times by which a manual switch which energizes the motor in a normal or reverse direction is operated. Therefore, the seat member can more accurately be returned to the originally set position.
    • 一种用于车辆驾驶员座椅的自动座椅定位装置,其中可逆电动机与电磁离合器之一接合并旋转,使得相关联的座椅构件致动机构将座椅构件中的一个从初始位置移动到特定驾驶员的期望位置, 最大可移动端。 在这样的上述结构的自动座椅定位装置中,对应于座椅构件的座位位置检测器,用于检测座椅构件到达检测器所在的特定位置,以及预设的计数器的预设控制电路, 通过计算马达的转数来表示座椅构件的设定位置,设定为与座椅构件从初始起始位置向特定位置移动的马达的转数相对应的值,使得 由于电动机重复启动停止而与电磁离合器接合时发生的滑移可以消除计数器的指示误差。 此外,自动座椅定位装置将设置在期望位置的座椅构件的位置数据从计数器的计数值存储在其中设置的存储器中,以便将座椅构件的当前设定位置返回到原始设定位置 在存储的数据的基础上。 在这种情况下,提供一种存储器校正电路,其响应于根据计数器的预设而将错误存储的数据校正到与实际位置相对应的精确值,该次数使得电动机在一个 正常或反向操作。 因此,座椅构件能够更准确地返回到原来的设定位置。

    • A first Peltier device Pe1 and at least one second Peltier device Pe2 having a current consumption smaller than that of the first Peltier device Pe1 are connected to each other in series, while a bypass circuit B for diverting an excess current I3 with respect to the second Peltier device Pe2 is connected to the second Peltier device Pe2 in parallel, so that a driving current I1 from a current control section A drives the first Peltier device Pe1 at its optimum operating point, and the excess current I3 with respect to the second Peltier device Pe2 in the driving current I1 is diverted into the bypass circuit B, so as to allow the second Peltier device Pe2 to be driven at its optimum operating point as well, where by the cooling efficiency can be improved. Also, the first and second Peltier devices Pe1, Pe2 are stacked on each other, while all the Peltier devices Pe1, Pe2 are driven by the single common current control section A, so as to attain a smaller size.
