Abstract: A seat-lifting device having a pair of left and right units 3, 4 arranged on both sides of a stool 1 in a toilet. The units 3, 4 are connected mutually by a connecting frame 5. Each unit 3, 4 has a guide portion 7 and a cable-driving portion 10 which are connected with a pair of conduits for guiding a cable. The guide portion 7 has a static guide 11, 14, a sliding plate 13 slidably supported with the static guide, a seat-supporting member 15 tiltably mounted on the sliding member, and a gas spring 17 urging the rear portion of the seat-supporting member. The sliding plate 13 is driven by the cable-driving portion through a loop of cable.

Abstract: A heat exchange mat comprises at least a pair of mat members respectively including a heat exchange element and arranged side by side with their one side edges opposed, an elongated link member acting as a partition and linking between the opposed side edges of the mat members while allowing the interior of the respective members to communicate with each other at one longitudinal end of the link member, and means for supplying and discharging a heat exchange fluid to one of the mat members and out of the other member through supply and discharge tubes provided close to each other, the means being mounted to the mat at the other end of the link member, whereby substantially uniform thermal distribution overall the heat exchange mat is attained with remarkable improvement in the heat exchanging efficiency at its installing place.
