Rotary mechanisms are provided. A rotary mechanism comprises a first member, a second member rotatable with respect to the first member along a first axis, and a first washer fixed to the first member. The first washer comprises a plurality of protrusions projecting toward the second member. The second washer is fixed to the second member and comprises a plurality of sliding surfaces, a plurality of depressions respectively disposed between the sliding surfaces, and a plurality of openings formed on the sliding surfaces. The protrusions are joined in the openings when the second member rotates to an angle with respect to the first member.

A composite film includes a substrate that is not responsive to relative humidity, and also one or more layers of hygromorphic material. The hygromorphic material expands in response to an increase in relative humidity and contracts in response to a decrease in relative humidity. In some cases, the composite film is bi-layer or tri-layer. The composite films are fabricated such that they undergo a desired bending pattern in response to changes in relative humidity. In some cases, these bending patterns are combinations of two bending primitives: a smooth curve and a sharply angled curve. These two primitives are combined to create a variety of shape transformations including 1D linear transformation, 2D surface expansion and contraction, 2.5D texture change and 3D folding. Any type of hygromorphic material may be employed, including living gram positive and gram negative bacterial cells, yeast cells, plant cells, mammalian cells, cell debris, or hydrogel.

A bendable, telescopic, and flexible mechanical structure comprises: a distal-end structure body, a proximal-end structure body, and a middle connecting body. The distal-end structure body comprises a distal-end spacing disc, a distal-end locking disc and a structure bone. The proximal-end structure body comprises a proximal-end spacing disc, a proximal-end locking disc and the structure bone. The middle connecting body comprises pipe fixing plates and a pipe. The distal-end structure body is connected to the proximal-end structure body through the middle connecting body. One end of the structure bone is fixed on the proximal-end locking disc. Then, the structure bone passes through the proximal-end spacing disc, the middle connecting body and the distal-end spacing disc sequentially, and is fixed on the distal-end locking disc.

摘要:
A light emitting device has a nanostructured layer with nanovoids. The nanostructured layer can be provided below and adjacent to active region or on a substrate or a template below an n-type layer for the active region, so as to reduce strain between epitaxial layers in the light emitting device. A method of manufacturing the same is provided.
