A sole component for footwear combining the desirable response characteristics of a fluid filled chamber and an elastomeric material is disclosed. The chamber can be formed as a single bladder chamber in contact with an elastomeric midsole or as a single chamber by a sealing a void in elastomeric material. Alternately, an insert having the shape of the bladder, and potentially formed from foam, may be positioned within the chamber. The interface between the chamber and elastomeric material is sloped and gradual so that the shape of the chamber and its placement in a midsole determine the combination of response characteristics in the sole component. The chamber has a relatively simple shape with one axis of symmetry with a rounded portion and a narrow portion.

A micromachined piezoelectric microspeaker and its fabricating method are disclosed. The micromachined piezoelectric microspeaker comprises a diaphragm and a plurality of contact pads. The diaphragm comprises an active area which is flat, and a non-active area which is wrinkled and surrounds the active area. The plurality of contact pads for electrodes are located outside of the diaphragm and over a wafer. And, the method comprises the steps of forming a compressive film on a wafer, forming a bottom electrode on a predetermined part of the compressive film of the front side of the wafer, forming a piezoelectric film on the bottom electrode and on the compressive film of the front side of the wafer, forming a bottom insulator film on the piezoelectric film, forming a top electrode on a predetermined part of the bottom insulator where the top electrode is located over some part of the bottom electrode, forming a top insulator film on the top electrode and on the bottom insulator film, forming contact pads for the bottom electrode and top electrode at an outside part of each electrode, and removing a predetermined part of the wafer which is located between wafer parts located under the each contact pads.

The present invention discloses an inertial sensor comprising a planar mechanical resonator with embedded sensing and actuation for substantially in-plane vibration and having a central rigid support for the resonator. At least one excitation or torquer electrode is disposed within an interior of the resonator to excite in-plane vibration of the resonator and at least one sensing or pickoff electrode is disposed within the interior of the resonator for sensing the motion of the excited resonator. In one embodiment, the planar resonator includes a plurality of slots in an annular pattern; in another embodiment, the planar mechanical resonator comprises four masses; each embodiment having a simple degenerate pair of in-plane vibration modes.

The present invention discloses an inertial sensor having an integral resonator. A typical sensor comprises a planar mechanical resonator for sensing motion of the inertial sensor and a case for housing the resonator. The resonator and a wall of the case are defined through an etching process. A typical method of producing the resonator includes etching a baseplate, bonding a wafer to the etched baseplate, through etching the wafer to form a planar mechanical resonator and the wall of the case and bonding an end cap wafer to the wall to complete the case.

The invention relates to an optical connector for connecting optical fibers. Said connector comprises a housing which is provided with a first opening for an optical cable comprising an optical fiber to be connected, and a second opening, through which the end of the optical fiber outwardly protrudes from the housing. The second opening can be closed by a lid which can be pivoted between a first position in which it closes the second opening, and a second position in which it frees the second opening. Spring elements are provided for prestressing the lid in the closing direction. The aim of the invention is to simplify the structure and especially the assembly of one such connector. To this end, the spring elements comprise a laminated spring.

A respiratory mask (10) that comprises a mask body (12) and a harness (21) that includes a carriage (22) and a strap (24). The mask body (12) lacks a rigid insert, is non-elastomeric, and is adapted for fitting over a person's nose and mouth. The mask body (12) has a nose portion (14), a chin portion (16), first and second cheek portions (18 and 20), and an axis (32) that extends from the nose portion (14) to the chin portion (16). The mask body (12) is constructed to deform such that the first and second cheek portions (18 and 20) move towards each other about the axis (32). The carriage (22) is joined to the mask body (12), and the strap (24) is joined to the carriage (22) for supporting the mask body (12) over a person's nose and mouth. When tension is applied to the strap (24) and an opposing force acts at the nose and chin portions of the mask body, the first and second cheek portions (18, 20) exhibit movement about the axis (32) towards each other. The respirator mask is beneficial in that it is lightweight, easy to manufacture, and maintains a good fit to a person's face.

A liquid ejection head includes a liquid chamber configured to contain liquid to be ejected from a nozzle, a liquid ejection member including the nozzle, and an energy generating element configured to provide energy to the liquid contained in the liquid chamber. The energy generating element ejects the liquid contained in the liquid chamber from the nozzle as a liquid droplet. A depression is formed on a surface of the liquid ejection member around the nozzle such that an opening of the depression has a width greater than a width of an opening of the nozzle and the nozzle is positioned at the bottom of the depression. The interior angle of the bottom corner of the depression is determined to be greater than 90 degrees.

Energy storing suspension components for use in suspension systems for wheeled vehicles and trailers are disclosed. The energy storing suspension components include an axle seat portion, an end, and a limb extending between the axle seat portion and the end. The limb includes a first taper wherein the limb decreases in width as the limb extends toward the end, a second taper wherein the limb decreases in thickness as the limb extends toward the end, wherein along the limb there is at least a portion where both the first taper and second taper are present, and a third taper that is further from the axle seat portion than the first taper and wherein the limb increases in width as the limb extends toward the end. Also disclosed are combinations of bushings and energy storing suspension components having an end configured to include an eye.

A keyboard device for an electronic keyboard instrument, which has a simple construction and can be manufactured at relatively low costs, and is capable of providing let-off feeling closely analogous to the let-off feeling of an acoustic piano. The keyboard device comprises keys, hammers each of which has an engaging part and pivotally moves in accordance with pivotal motion of an associated key, an unmovable holder, and let-off members each formed of an elastic material, for temporary engagement with the engaging part of an associated hammer during each of key depression and key release, to impart let-off feeling to touch feeling of an associated key during key depression. Each let-off member extends from the holder to a pivotal path along which the associated hammer performs pivotal motion, and is compressed during key depression and deflected during key release by engagement with the engaging part.
