Abstract: PROBLEM TO BE SOLVED: To ensure a sufficient horizontal communicable range in near field wireless transfer that utilizes extremely low-power UWB (Ultra Wide Band) but does not use polarization characteristics. SOLUTION: A coupling electrode is disposed at a place offset from a center of a reading surface, and an action of moving the place of the coupling electrode within the read plane in accordance with a change in placement posture of a body of a cradle 70, is utilized. A communicable range of the coupling electrode is 2-3 cm but since the communicable range moves according to a change in placement posture, it may be comprehensible to expand the communicable range over all the read plane. The communicable range may be expanded to three times, at a maximum, vertically from a horizontal plane whereon the cradle 70 is installed. COPYRIGHT: (C)2011,JPO&INPIT

Abstract: PROBLEM TO BE SOLVED: To provide a D/A conversion circuit with high precision where a stable voltage output can be acquired independently of a load circuit and to suppress interference among the D/A conversion circuits in the case of employing a plurality of the D/A conversion circuits. SOLUTION: A differential comparator circuit 50 compares a differential output voltage (Vout-Vxout) with a differential reference signal (VA-VB) and controls a count value cnt of an up-down counter 60 according to its comparison signal cmp. A switch S3 of a reference voltage correction 70 is controlled depending on the count value cnt to control a level of a reference voltage V1. A comparator circuit 10 compares the reference voltage V1 with a voltage V2, outputs a comparison signal V3 to control an output current of each of a current source 12 and a current source circuit 22. Then a maximum value of a differential output voltage is independent of a load circuit and kept to a level nearly equal to that of the differential reference signal and then a stable voltage output can be realized.
