  • Publication number: 20240284798
    Abstract: [Object] To provide a thermoelectric body that can be deposited on any substrate, which is not limited to a single crystal bulk material or an epitaxially grown thin film, and is capable of exhibiting high coercive force and residual magnetization with respect to in-plane magnetization. [Solving Means] A thermoelectric body that is a magnetic film for use in a thermoelectric generation element utilizing an anomalous Nernst effect, characterized by having an easy axis of magnetization in an in-plane direction and an amorphous structure. Favorably, the thermoelectric body is characterized in that SmpCo100-p (0<p?50) or Smp(FeqCo100-q)100-p (0<p?50, 0?q?100) is included.

  • Patent number: 6994065
    Abstract: An intake arrangement for an internal combustion engine, including an intake manifold including an intake collector and a plurality of branch pipes connected with the intake collector. The branch pipes extend in substantially same direction. The intake collector includes an inlet opening through which an intake air flow is introduced into the intake collector, and branch openings to which branch pipes are connected. The branch openings are arranged along a longitudinal direction of the intake collector such that as a distance thereof from the inlet opening decreases, an amount of offset thereof from a reference streamline of the intake air flow extending through substantially a center of the inlet opening along the longitudinal direction of the intake collector increases.

  • Patent number: 6920858
    Abstract: An air intake structure of a multiple cylinder internal combustion engine. The air intake structure includes an intake air collector having first and second end sides which are longitudinally opposite to each other. An intake air inducting pipe is connected to the intake air collector. A plurality of branch pipes are connected to the intake air collector. Each branch pipe is connected through a junction section of the branch pipe to the intake air collector. The intake air inducting pipe has an opening section which is located between a first branch pipe located at the first end side of the intake air collector and a second branch pipe located adjacent to the first branch pipe in a longitudinal direction of the intake air collector. The opening section has an axis directed to a third branch pipe located at the second end side of the intake air collector.
