    摘要: 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.

    摘要: A navigation instrument comprises a first counter for counting travelling distance from a start point, a second counter for counting travelling time from starting, a means for setting a scheduled average vehicle speed, an arithmetic means for calculating average vehicle speed, the deviation of travelling distance from the scheduled distance and the deviation of travelling time from the scheduled time, and a display means for displaying the result of calculation. The first counter is capable of subtractively counting travelling distance in response to switching operation of a switching means which is incorporated to the first counter. The first counter is also incorporated with a means for stopping navigating operation which is operative when the first counter counts down the travelling distance until a given value.
