A cooker with a gasket may include a top plate on which a plurality of burners may be placed; a manifold panel provided in front of the top plate and including thereon a plurality of knobs to control output powers of the plurality of burners; and a gasket that extends along a front end of the top plate and is compressed between the top plate and the manifold panel to hermetically seal the top plate and the manifold panel.

[Problem] To provide a foldable frame structure, unfoldable into a 2N-sided polygonal shape (N being an integer equal to or larger than 2), achieving a securely and rigidly supported unfolded state and a compact folded state. [Solving means] 2N upper rods (210), with an equal length, are coupled to each other to define a planer 2N-sided polygonal shape. First coupling means (220) coupling two adjacent upper rod (210) at a corresponding one of apices of the 2N-sided polygonal shape, and holding the two upper rod (210) in such a manner that the upper rod (210) are rotatable about an orthogonal axis orthogonal to axes of both of the two rods and rotation means (240) that enable each of the upper rods (210) to rotate about the axis (AX1) are provided. Folding to be a columnar shape as a whole can be achieved with the upper rods (210) pivoted about the orthogonal axis (AX2) to minimize an angle between two adjacent upper rods (210) while the upper rods (210) are rotated about the axis (AX1).

A hollow profile and a method of producing the hollow profile from a hardenable steel alloy blank is disclosed having an L-shaped cross section with an upper vertical hollow chamber, and a lower horizontal hollow chamber, wherein the blank comes in abutment on an intermediate bridge area, forming a double layer. The hollow profile further includes, at least in regions, a tensile strength Rm greater than 1000 MPa.

Miura-Ori-like origami, corresponding to a smoothly varying tessellation of unit cells, each of which is composed of a 22 grid of quadrilaterals, is employed to closely approximate a curved surface by one that can be easily collapsed and deployed. The unit cells do not necessarily perfectly repeat, but do vary smoothly across the origami pattern.

A structural body includes: a three-dimensional net shaped body including a plurality of net lines that form a three-dimensional net shape; and a plurality of objects respectively present in two or more of a plurality of spaces partitioned by the plurality of net lines. The plurality of objects are each a mobile object that moves within one of the plurality of spaces or moves over two or more of the plurality of spaces.

A reinforced structure is disclosed which includes a structural component as well as a reinforcing part that is arranged in a cavity of the structural component. The reinforcing part can include a support part and a connection, the support part being arranged in the cavity such that a distance between the support part and the structural component at a position of the structural component with a higher probability of deforming under a force load from outside on the structural component is shorter than at a position of the structural component with a lower probability of deforming under a force load from the outside.
