摘要： A vibration-type actuator capable of suppressing reduction in holding torque or holding force under influence of humidity. A vibration-type actuator 10 includes a vibrating body 2 and a driven body 1. The vibrating body 2 has a piezoelectric element 2c and an elastic body 2b. The driven body 1 is in contact with the vibrating body 2. The vibration-type actuator 10 moves the vibrating body 2 and the driven body 1 relatively to each other by vibration excited to the vibrating body 2. At least one of a first contact portion of the vibrating body 2 and a second contact portion of the driven body 1 includes a stainless-steel sintered body with pores and at least some of the pores are impregnated with a resin.

摘要： A composite material fabricated using a novel process and materials. The piezoelectric and magnetostrictive layers of the composite material are coated, layered, and bonded using a process known as LTTLP bonding. The resulting magnetoelectric composite fibers are bonded to a polyimide film based copper flexible circuit using a room temperature curing epoxy. The sensor that results is an MEMFC that outperforms conventionally fabricated MEMFCs.

摘要： A subtractive forming method that includes providing a material stack including a samarium and selenium containing layer and an aluminum containing layer in direct contact with the samarium and selenium containing layer. The samarium component of the samarium and selenium containing layer of the exposed portion of the material stack is etched with an etch chemistry comprising citric acid and hydrogen peroxide that is selective to the aluminum containing layer. The hydrogen peroxide reacts with the aluminum containing layer to provide an oxide etch protectant surface on the aluminum containing layer, and the citric acid etches samarium selectively to the oxide etch protectant surface. Thereafter, a remaining selenium component of is removed by elevating a temperature of the selenium component.

摘要： A power generator 1 includes a magnetostrictive element 10, a fixing member 7 for supporting a proximal end portion of the magnetostrictive element 10, a permanent magnet 6 and a loop forming member 8 fixedly attached to the fixing member 7 through the permanent magnet 6. The power generator 1 is used in a state that the fixing member 7 is fixedly attached to a housing of a vibrating body generating vibration or the like. The magnetostrictive element 10 is supported by the fixing member 7 so that a distal end portion of the magnetostrictive element 10 can be displaced with respect to the proximal end portion of the magnetostrictive element 10. The loop forming member 8 is arranged so as not to interfere with the magnetostrictive element 10 when the distal end portion of the magnetostrictive element 10 is displaced with respect to the proximal end portion of the magnetostrictive element 10. Further, the loop forming member 8 forms a loop in cooperation with the magnetostrictive element 10 and the fixing member 7 so that lines of magnetic force generated from the permanent magnet 6 return back to the permanent magnet 6 after circulating in the loop.

摘要： The invention provides a transducer comprising conductors and a laminate. The laminate comprises a film of a dielectric polymer material arranged between first and second electrodes. Each electrode is in electrically conductive communication with at least one of the conductors to facilitate an electrical potential between the electrodes and thereby enable deflection of the polymer material in response to an electrical field. At least one of the conductors is an elastically deformable conductor comprising a compliant core which is electrically conductive. The core is enclosed in a containment having elastomeric properties.

摘要： Passivated micromechanical resonators and related methods are described. Applicants have appreciated that polycrystalline conductive layers used as electrodes for some MEMS resonators are a source of mechanical and electrical instability. To inhibit or prevent contamination of such conductive layers, which may exacerbate the instabilities, passivation structures are used. The passivation structures can be grown, deposited, or otherwise formed.
