Abstract: A mounting structure minimizes the influence of displacements, along a length direction of a resistor, in mounting positions of capacitor electrodes on the electrical characteristics of a circuit including a parallel circuit composed of a capacitor and the resistor. The capacitor has first and second electrodes, which respectively include first and second side surface portions disposed in parallel to a length direction of the resistor. The resistor has a first resistance body corresponding to the first side surface portions and a second resistance body corresponding to the second side surface portions that are separately disposed along the length direction and connected in series via a wire, and is mounted so that the first resistance body is positioned directly facing the first side surface portions and the second resistance body is positioned directly facing the second side surface portions.

Abstract: A current detector includes a ring-shaped core for inserting a wire; a detection winding on the core; and resistor connectors for connecting a resistor in series to the detection winding. The detection winding has a first winding at a first end and a second winding at a second end that are connected in series. The first winding and second winding each have n (where n is three or higher) first or second unit windings in series. The core surface is partitioned into 2n regions around the core. The first unit windings are formed in odd-numbered regions and the second unit windings are formed in even-numbered regions. A jth (where j is 1 to n) first unit winding from the first end and a jth second unit winding from the second end are not adjacent and are formed with an equal number of turns.

Abstract: A current sensor includes: a magnetic core that surrounds a detected object; a first sensor with a first sub-magnetic core incorporated in the magnetic core and a first winding wound around the first sub-magnetic core; a second sensor with a second sub-magnetic core incorporated in the magnetic core and a second winding wound around the second sub-magnetic core in the opposite direction to the first winding; a signal generator outputting signals to magnetize the first and second windings with inverted phases; a detector outputting a detection signal whose amplitude is proportionate to a current in the detected object based on the difference between first and second voltage signals generated in the first and second windings; and a waveform adjuster that is connected to at least one of the first and the second windings and adjusts the waveform of a voltage signal generated by the connected winding.

Abstract: A system for automatically connecting a seat back to a seat cushion to assemble a seat, which includes a first setting device for setting the seat back upright, a second setting device for setting a seat cushion horizontally, and a robot hand device. The seat back is easily set on the first setting device, with a part of its upholstery being turned up by a retaining element of the same first setting device to expose the associated connecting member. The robot hand device includes a pressure arm element to pressingly hold such turned-up part of seat back upholstery. The seat back is transferred by the robot hand device to the second setting device, maintaining such turned-up state of the upholstery part all the way, so that the exposed connecting member of seat back is connected to another connecting member of seat cushion by operation of an automated connecting device of said second setting device, thereby forming a resulting seat.
