  • Publication number: 20240180035
    Abstract: A thermoelectric power generation system includes a shell-and-tube heat exchanger configured such that a tube including double tubes of an inner tube and an outer tube is inserted into a shell, and a thermoelectric power generation module inserted into between the inner tube and the outer tube. The thermoelectric power generation module generates thermoelectric power using a temperature difference between a first medium flowing in the inner tube, such as coolant, and a second medium flowing outside the outer tube in the shell, such as excess water vapor.

  • Publication number: 20240147857
    Abstract: A thermoelectric power generation system 20 includes a heat exchanger 1 having double tubes which are an inner tube 1a and an outer tube 1b, and a thermoelectric power generation module 2 mounted between the inner tube and the outer tube. The thermoelectric power generation module generates thermoelectric power using a temperature difference between a medium inside the inner tube and a medium outside the outer tube, and a highly thermal conductive elastic sheet 3a, 3b is mounted between the thermoelectric power generation module and the inner tube and/or the outer tube in close contact therewith.

  • Publication number: 20210328255
    Abstract: One aspect of the present invention is a nonaqueous electrolyte energy storage device including a positive electrode containing manganese-containing positive active material particles in which aluminum is present at least on a surface, and a nonaqueous electrolyte containing a salt represented by the following formula (1). Another aspect of the present invention is a method of producing a nonaqueous electrolyte energy storage device, including producing a positive electrode containing manganese-containing positive active material particles in which aluminum is present at least on a surface, and providing a nonaqueous electrolyte containing a salt represented by the following formula (1): wherein R1 is a hydrogen atom, a halogen atom, or an organic group, Mm+ is an alkali metal cation, an alkaline earth metal cation, or an onium cation. m is an integer equivalent to the number of valence of a cation represented by Mm+. when m is 2 or more, a plurality of R1s are each independently as defined above.

  • Patent number: 7172476
    Abstract: An outboard motor includes a drive unit and a bracket assembly mounting the drive unit on an associated watercraft. The bracket assembly includes a swivel bracket that carries the drive unit for pivotal movement about a steering axis that extends generally vertically, and a clamping bracket that supports the swivel bracket and the drive unit for pivotal movement about a tilt axis that extends generally horizontally. Either the swivel bracket or the clamping bracket, at least in part, has a first flange, a second flange spaced apart from the first flange, and a web that extends between the first and second flanges to connect together the first and second flanges. The first and second flanges extend generally parallel to the tilt axis. The web extend generally normal to the tilt axis.
