Publication number: 20080164098Abstract: A method and apparatus for controlling human scent from hunters in tree stands. The apparatus in its preferred form is a portable tree stand in combination with a heat shield and a heater holder selectively attached to the bottom of the tree stand foot platform to define a plenum and a portable heater holder. In operation the heater, such as a propane heater, heats the air in the plenum which expands and rises like all warm air and carries with it the human scent which is then directed up past the body and away.Type: ApplicationFiled: January 4, 2007Publication date: July 10, 2008Inventors: JOHN E.

Publication number: 20080164100Abstract: An oil path structure includes: a motor case having a joint surface and having a cooling oil path opened to the joint surface formed therein; a generator case having a cooling oil path formed therein and joined to the joint surface such that the cooling oil paths communicate with each other; an O-ring sealing between the cooling oil paths; and a plain washer limiting the flow rate of oil passing through the oil path. In the generator case, a recessed portion is formed at a position adjacent to the joint surface and on route of the cooling oil path. In the recessed portion, the O-ring in contact with the joint surface and the plain washer positioned on the side of O-ring opposite to the joint surface are arranged. The plain washer is sandwiched between the O-ring and a bottom surface. Thus, an oil path structure can be provided that ensures reliable sealing and allows flow rate adjustment with a simple structure.Type: ApplicationFiled: March 22, 2006Publication date: July 10, 2008Applicants: TOYOTA JIDOSHA KABUSHIKI KAISHA, AISIN AW CO., LTDInventors: Yumi Iraha, Masatoshi Adachi, Kazutoshi Motoike, Jun Ichiyanagi
