Mitral valve device using conditioned shape memory alloy
A mitral valve annulus reshaping device includes at least a portion that is formed of a biocompatible shape memory alloy SMA having a characteristic temperature, Af, that is preferably below body temperature. The device is constrained in an unstable martensite (UM) state while being introduced through a catheter that passes through the venous system and into the coronary sinus of the heart. The reshaping device is deployed adjacent to the mitral valve annulus of the heart as it is forced from the catheter. When released from the constraint of the catheter, the SMA of the device at least partially converts from the UM state to an austenitic state and attempts to change to a programmed shape that exerts a force on the adjacent tissue and modifies the shape of the annulus. The strain of the SMA can be varied when the device is within the coronary sinus.

A manually operated trigger sprayer is constructed with a reduced number of parts and in a novel manner in which all of the component parts of the sprayer are constructed of a plastic material. The construction of the trigger sprayer replaces the conventional metal coil spring in the pump chamber with a pair of plastic bowed springs that are integral with the piston rod and are positioned outside the pump chamber. Constructing all of the sprayer parts of a plastic material enables a cost efficient recycling of the parts, which does not require disassembling the parts to remove a metal spring.

A heliostat 5 for use in a sunlight concentration system for utilizing sunlight as energy according to this invention has a plurality of small concave mirror elements 8 and reflects and focuses sunlight reflected off the individual concave mirror elements to a light concentration portion as if upon reflection off a single large concave mirror 9. The angles of the concave mirror elements 8 are changed to define a single concave mirror having a predetermined curvature. When the incident angle of sunlight with respect to the concave mirror is large, the curvature is reduced (like a shallow dish). When the incident angle is small, the curvature is increased (like a deep dish).

The invention relates to a bionic impeller for an exhaust hood. The bionic impeller is applied to the exhaust hood and comprises a plurality of groups of annular end surfaces and blades. The corresponding blades are uniformly in bridge connection between each two groups of annular end surfaces. The bionic impeller is characterized in that the blades are bionic blades, the front edges of the bionic blades face a suction side of the exhaust hood and are of wavy structures, and the tail edges of the bionic blades face a blowout side of the exhaust hood and are of sawtooth structures. The bionic impeller has the advantages that pressure impact on the front edges of the blades and vortex-shedding frequencies of the tail edges of the blades can be reduced advantageously, and accordingly pneumatic noise generated when the impeller works can be reduced; extended areas of the blades can be reduced by 13.5% as compared with blades in original shapes, accordingly, the weight of the impeller can be reduced, loads on a motor can be decreased, and the efficiency of a fan can be improved advantageously.

A loudspeaker system containing wave-shaping sound chambers with approximately rectangular inlets and outlets of substantially the same size that are used to flatten or control the curvature of the acoustic wavefronts contained within system waveguides. Control of the degree of curvature of the wavefront enables the development of a wide variety of multi-waveguide arrays. The sound chambers are placed between a waveguides and a flattened conical horns of secondary waveguides. The sound chambers transform the curvature of the typical fan shaped wavefront that results from a conical horn throat into a wavefront that approximates a planar or curved rectangular ribbon of sound.

A vehicle is provided with: an EPS a VGRS actuator as a rudder angle varying device; and an EPS actuator as a steering torque assisting device. In following a target driving route, a LKA target assist torque TLK is outputted from the EPS actuator on the basis of target lateral acceleration GYTG. On the other hand, in order to suppress the steering of a steering wheel by the assist torque, which is against a driver's will, steered wheels are steered by the VGRS actuator, excessively by a LKA correction target angle θLK. At this time, it does not influence a relation between a steering angle and the rotation angle of a lower steering shaft. Thus, the following for the target driving route is realized without reducing the robustness of the vehicle with respect to the driver's steering.
