2668results about How to "Improve deformation" patented technology

A method is disclosed for utilizing a deformable article of manufacture formed at least partly of a shape memory alloy. The method includes the steps of deforming the article from a first predetermined configuration to a second predetermined configuration while the shape memory alloy is, at least partially, in its stable martensitic state and at a first temperature. A resisting force is applied to the deformed article of manufacture using a restraining means and the article is heated from the first temperature to a second temperature in the presence of the resisting force. The stable martensitic state is transformed to a metastable stress-retained martensitic state. The resisting force is then removed allowing the alloy to transform to its austenitic state and the shape of the article to be restored substantially to its first configuration. Devices primarily medical devices operative by employing this method are also disclosed.

A clip for engaging tissue includes a generally annular-shaped body defining a plane and disposed about a central axis extending normal to the plane. The body includes alternating inner and outer curved regions, defining a zigzag pattern about a periphery of the clip. The body is biased towards a planar configuration lying in the plane and deflectable towards a transverse configuration extending out of the plane. Tines extend from the inner curved regions, the tines being oriented towards the central axis in the planar configuration, and parallel to the central axis in the transverse configuration. The tines include primary tines and secondary tines that are shorter than the primary tines. The primary tines may be disposed on opposing inner curved regions and oriented towards one another. The primary tines are configured such that they are offset from the axes of symmetry of the curved regions from which they extend and are connected to the curved regions by curved or linear regions or are connected directly to the curved regions. The primary tines may overlap the body and may be of different lengths.

The dielectric-varied capacitive flexible three-dimensional force tactile sensor is characterized in that a flexible printed circuit board is arranged, wherein a square common electrode and four identical rectangular induction electrodes which are located on the periphery of the edges of the common electrode in an equidistant mode are printed on the printed circuit board; the induction electrodes are in two-to-two symmetry with the center of the common electrode serving as the symmetry point; a composite multi-dielectric layer is fixed to the flexible printed circuit board; the composite multi-dielectric layer is formed by an inversely-concave PDMS dielectric layer and an air dielectric layer located in a groove of the PDMS dielectric layer; the composite multi-dielectric layer is buckled on the upper portion of the flexible printed circuit board, and the common electrode and the four induction electrodes are located in the air dielectric layer; a PDMS hemispheric contactor is arranged on the composite multi-dielectric layer. According to the dielectric-varied capacitive flexible three-dimensional force tactile sensor, the common electrode and the induction electrodes are located on the same plane; compared with a traditional capacitive tactile sensor of an up-down electrode structure, the dielectric-varied capacitive flexible three-dimensional force tactile sensor has the advantages of being simple in manufacturing process and capable of being easily arrayed.

Part of a front side frame is configured to be deformed so as to bend outwardly, in a vehicle width direction, by a collision load in a vehicle frontal collision. A sub frame provided at a lower portion of a front vehicle body is joined to the front side frame via a reinforcement. A front portion of the reinforcement is located at a position which corresponds to a bending portion of the front side frame which is to be deformed so as to bend outwardly, in the vehicle width direction, by the collision load in the vehicle frontal collision. Accordingly, the bending of the front side frame at its bending portion when the collision load acts in the vehicle frontal collision can be promoted, so that the collision load against passengers can be decreased securely.

A three-dimensional knit fabric having front and back knit layers and a monofilament yarn connecting the knit layers to each other, characterized in that the curvature of the monofilament yarn in the three-dimensional knit fabric is in a range from 0.01 to 1.6, and the bending elongation of the monofilament is 20% or less when the three-dimensional knit fabric is compressed to 50%. The three-dimensional knit fabric has a cushioning property in springiness which does not deteriorate even if the fabric is repeatedly used many times or for a long time, and thus this fabric is excellent in terms of durability of the cushioning property. In particular, the fabric is suitable for use as a hammock type seat and exhibits a cushioning property having a favorable springy feeling as well as a good fit feel.

The method can be used for building a large cross-section tunnel in a safe, rapid and economic manner.

An iron club head includes a striking plate for striking a golf ball and a body. The body includes an elastically deformable thin wall. An opening is defined in a front side of the body and surrounded by the thin wall. The striking plate is bonded in the opening. The thin wall has a thickness smaller than that of the striking plate. When the iron club head hits a golf ball, a momentum of striking generated as a result of hitting the golf ball causes elastic deformation of the striking plate and the thin wall to increase an overall deformation of the iron club head.

A sole structure 1 for a shoe comprises an upper plate 2 having a heel region and disposed on the upper side of the structure 1, a first C-shaped portion 3 and a second C-shaped portion 4 each having a longitudinally flat, generally C-shape with an upwardly opening portion 3A, 4A, disposed alongside in the longitudinal direction under the upper plate 2, and each opening end of the upwardly opening portions 3A, 4A directly fixed to the upper plate 2, and a connecting portion 5 interposed between and connecting the first and second C-shaped portions 3.

The high pressure fluid passages (63) include inlet fluid passages (65a, 65b) defined by inlet ridges (50a to 50c) extending from a compressed air inlet (19), and main fluid passages (64) defined by a plurality of main ridges (49) extending parallel to each other in the longitudinal direction of the second heat transfer plates (42) so as to be perpendicular to the inlet fluid passages (65a, 65b). The two inlet fluid passages (65a, 65b) have different widths (Wa, Wb), and gaps (α, β) are formed between the downstream ends of the two inlet ridges (50b, 50c) and the upstream ends of the main ridges (49). A high pressure fluid can thereby be uniformly distributed into the main fluid passages (64) connected to the inlet fluid passages (65a, 65b) of the high pressure fluid passages (63) of the heat exchanger.
