摘要： A deformable sensor system that can be used for pressure-distribution sensors. The deformable sensor system makes it possible to obtain a pressure distribution with a much higher accuracy, while reducing the number of electrodes. The system utilizes a deformable sensor which can detect deformation as the electric resistivity of the surface increases monotonically as an elastic deformation variation in each of the elastic deformations increases. Based on a voltage being detected by means of a detecting unit, the deformable sensor electric-resistivity variation computing unit computes the variation of the electric resistivity based on the method of least squares with a restriction condition imposed thereon. The system uses such a technology as “EIT” that is based on an inverse-problem theory. At an external-force position computing unit, a position in a pressure-receiving surface, position which receives an external force, is computed based on the computed electric-resistivity variation.

摘要： To provide a deformable sensor system, which makes it possible to obtain a pressure distribution with a much higher accuracy, while reducing the number of electrodes.A deformable sensor 12 comprises an elastic material whose electric resistivity, when all types of elastic deformations are caused therein respectively, increases monotonically as an elastic deformation variation in each of the elastic deformations increases. Based on a voltage being detected by means of a detecting unit 22, the deformable sensor 12's electric-resistivity variation δρ(x, y), which minimizes an evaluation Function J of Equation (1) while satisfying a condition of Equation (2), is computed at an electric-resistivity variation computing unit 25 using such a technology as “EIT” that is based on an inverse-problem theory. At an external-force position computing unit 26, a position in a pressure-receiving surface 12a, position which receives an external force, is computed based on the computed electric-resistivity variation δρ(x, y). J=∥δV(m,n)−Sm,n,x,y·δρ(x,y)∥2 (1) However, δρ(x,y)≧0 (2)

摘要： A crosslinked elastomer body is composed of an electrically conductive composition comprising an electrically conductive filler and an insulative elastomer (matrix). The electrically conductive filler is in a spherical particulate form and has an average particle diameter of 0.05 to 100 μm. The electrically conductive filler has a critical volume fraction (φc) of not less than 30 vol % as determined at a first inflection point of a percolation curve at which an insulator-conductor transition occurs with an electrical resistance steeply reduced when the electrically conductive filler is gradually added to the elastomer. A resistance observed under compressive strain or bending strain increases according to the strain over a resistance observed under no strain when the electrically conductive filler is present in a volume fraction not less than the critical volume fraction (φc) in the composition.

摘要： A fluid-filled elastic mount (10) wherein a fluid-tight space (40) defined by two mounting members (12, 14), an elastic body (16) and a flexible diaphragm (36) is divided by a partition member (34) into pressure-receiving and an equilibrium chambers (44, 46) communicating with each other through a first orifice (64). The partition member has a communication hole (62) for fluid communication of the first orifice with the equilibrium chamber. The elastic mount has a cover member (76) which cooperates with the diaphragm to define a space in which a pushing member (84) is accommodated such that it is pressed onto the diaphragm by a biasing member (86), so that the diaphragm closes the communication hole. The pushing member cooperates with a rubber plate (94) to divide the space within the cover member into static pressure and operating chambers (96, 100), and the pushing member is sucked toward the cover member by a negative pressure applied to the operating chamber, so that the diaphragm is displaced away from the communication hole to open the same for fluid communication of the orifice with the equilibrium chamber.

摘要： A fluid-filled elastic mount wherein an elastic body elastically connecting a first and a second support partially defines a fluid chamber filled with a non-compressible fluid. The elastic mount includes an oscillating plate which partially defines the fluid chamber and which is supported by the second support such that the oscillating plate is displaceable relative to the second support, and an actuator for oscillating the oscillating plate to thereby change a pressure of the fluid in the fluid chamber. The elastic mount further includes an elastic support member for flexibly connecting the oscillating plate to the second support such that the oscillating plate is movable toward and away from the fluid chamber. This elastic support member is formed of an elastic material which substantially permits shearing deformation of the elastic support member and inhibits its compressive and tensile deformation.

摘要： A fluid-filled elastic mount including a first and a second support member, an elastic body for elastically connecting the two support members, and a closure member fixed to the second support member to form a fluid chamber therein. The closure member includes a flexible diaphragm and a metallic member secured to the outer periphery of the diaphragm. The metallic member is press-fitted in a large-diameter portion of the second support member remote from the first support member, and fixed by caulking to the large-diameter portion. At least one sealing rubber lip is pressed between the metallic member and the second support member to assure the fluid tightness of the fluid chamber. Further, a fluid discharge passage is formed radially outwardly of the sealing rubber lip(s), between the metallic member and the large-diameter portion of the second support member, for permitting the fluid to be discharged from the fluid chamber. Also disclosed is a method of producing such a fluid-filled elastic mount.
