  • Patent number: 9827638
    Abstract: Each heat exchange tube of a condenser is formed of a first brazing sheet having a core material and a first brazing material covering the core material. The tank body of each header tank is formed of a second brazing sheet having a core material and a third brazing material covering the core material and being lower in flowability than the first brazing material. In a region of a surface of each protrusion portion facing the corresponding heat exchange tube, the region having a predetermined width as measured from the projecting end, the core materials of the two brazing sheets are brazed together by means of the first brazing material. In the region other than the brazed portion, the core materials of the two brazing sheets are brazed together by means of a fillet formed of a mixture of the first and third brazing materials.

  • Publication number: 20160273204
    Abstract: A flush toilet enabling easy cleaning besides capable of preventing dirty water from flowing out is provided. In the flush toilet, a toilet seat is placed on a rim of a toilet body with the toilet seat free to open and close on a pivot axis on a side of a rear end thereof. A projection rib for preventing dirty water from flowing out is formed on a front upper face of the rim so that it protrudes from an outer periphery of the rim. The projection rib is provided so that it is outside a front periphery of the toilet seat when the toilet seat is in closing state.
