20100126270 | INERTIA FORCE SENSOR - An inertial force sensor includes a weight, a first fixing portion linked to the weight, a second fixing portion linked to the weight via the first fixing portion, a first electrode on a first surface of the weight, a second electrode facing the first electrode, and first and second elastic portions elastically deforming so as to displace the weight. The first elastic portion displaces the weight along an X-axis but not along any of a Y-axis and a Z-axis. The second elastic portion displaces the first fixing portion along the Y-axis but not along any of the X-axis and the Z-axis. This inertial force sensor detects an acceleration at high sensitivity. | 05-27-2010 |
20100149777 | ELECTRONIC CIRCUIT CONNECTION STRUCTURE AND ITS MANUFACTURING METHOD - First sheet-like substrate is arranged at a region surrounded by first terminals of male connector and first circuit substrate, and second sheet-like substrate is arranged at a region surrounded by second terminals of female connector and second circuit substrate, and male connector and female connector are fitted together so that a first passive element of first sheet-like substrate and a second passive element of second sheet-like substrate configure a filter circuit. | 06-17-2010 |
20120227489 | ANGULAR VELOCITY SENSOR - An angular velocity sensor includes a support body, a retaining portion connected to the support body, first to fourth weights, first to fourth arms, a drive unit for driving the first to fourth arms, and a monitor unit for detecting displacements of the first to fourth arms. An X-axis, a Y-axis, and a Z-axis that are perpendicular to each other are defined. The detector unit is symmetrical with respect to both an axis parallel to the X-axis and an axis parallel to the Y-axis. This angular velocity sensor can cancel an undesired signal caused by external disturbances, such as acceleration or impact, thus detecting an angular velocity accurately. | 09-13-2012 |
20120255358 | ACCELERATION SENSOR - An acceleration sensor includes a frame, a weight portion, an arm portion for connecting the frame and the weight portion, and a sensing portion for detecting a bend of the arm portion. The sensing portion includes a first electrode portion, a second electrode portion, and a strain resistor portion. The first electrode portion and the second electrode portion are provided on the weight portion. A first end of the strain resistor portion is connected to the first electrode portion, and a second end of the strain resistor portion is connected to the second electrode portion. The strain resistor portion is formed of a strain resistor film comprising a metal oxide. The strain resistor portion is formed in meander shape in the part which is nearer to the weight portion than the frame in the arm portion. | 10-11-2012 |
20130283914 | ACCELERATION SENSOR - An acceleration sensor includes a frame having a hollow space at an inside thereof, four beams extending from the frame to the hollow space, four plummets connected to ends of the four beams, and four sensing units provided on the four beams. One ends of the beams is connected to portions of the frame opposite to each other with respect to the hollow space. The two plummets face each other across the center of the hollow space. One ends of the other two beams are connected to portions of the frame opposite to each other with respect to the hollow space. The other two plummets face each other across the center of the hollow space. This acceleration sensor reduces variations and temporal changes in its sensitivity. | 10-31-2013 |
20130307094 | SENSOR - A sensor includes a circuit board, a wiring connection layer, a sensor element, and a conductive post. The circuit board has a first electrode. The wiring connection layer has second and third electrodes. The second electrode is connected to the first electrode. The sensor element has a fourth electrode. The conductive post connects the third electrode electrically with the fourth electrode. This sensor can be driven efficiently. | 11-21-2013 |
20150059430 | INERTIAL FORCE SENSOR - An inertial force sensor includes a fixed part, a beam connected to the fixed part, a plummet connected to another end of the beam and being displaceable due to inertial force to cause the beam to deform, a conductive part provided at the plummet, a strain-sensitive resistor provided at the beam for detecting a deformation of the first beam, first and second fault diagnostic electrodes provided at the fixed part, a first fault diagnostic wiring for connecting the first fault diagnostic electrode to the conductive part through the beam, and a second fault diagnostic wiring for connecting the second fault diagnostic electrode to the conductive part through the beam. The inertial force sensor does not continue to output an erroneous output signal when a crack occurs in the plummet, thus having high reliability. | 03-05-2015 |
20160084870 | SENSOR - A sensor includes a first substrate, a supporter connected to the first substrate, a weight facing the first substrate, a beam of which first end is connected to the supporter and of which second end is connected to the weight, a second substrate facing the weight, and a first projection disposed on the first substrate. This senor allows effectively preventing the beam from a breakage caused by the beam twisted due to a rotation of the weight when an impact is applied to the sensor. The sensor thus can improve anti-impact property. | 03-24-2016 |
