A circular annular seal ring made from a resin is adapted to be disposed between an outer member and an inner member that rotate relative to each other. The seal ring is disposed in a circumferential groove of the outer member or the inner member to isolate a liquid space from an external space. The seal ring is formed from an elongated and arcuate rod to define a circle by joining ends of the rod, and has a junction formed from the ends. The seal ring has a radial thickness gradually decreasing from two points that are apart from the junction toward the junction. The points are separated from the junction by an angle of not less than 60 degrees and not more than 150 degrees about a central axis of the circle.

Seal ring

The seal ring is annular around an axis x and includes an annular outer peripheral surface facing an outer periphery side, and a plurality of recessed parts. The recessed parts are formed in such a way as to be spaced apart from each other in a circumferential direction and are recessed from the outer peripheral surface toward an inner periphery side. The recessed parts expand, in the axis x direction, from one side surface to a position which does not reach another side surface. The outer peripheral surface includes a annular contact surface between the another side surface and the position, and rib surfaces respectively between mutually neighboring recessed parts in the circumferential direction. Each of the rib surfaces extends between the one side surface and the position in the axis x direction.

A seal ring has, on an outer peripheral surface side thereof, a pair of recessed partsextending in a circumferential direction on both sides in a width direction thereof to form a projection partbetween the pair of recessed parts, and has a plurality of ribsconnected to the projection partand extending to lateral surfaces of the seal ring at intervals in the circumferential direction inside the pair of recessed parts, and a plurality of ribsarranged on a sealed region side among the plurality of ribshave lateral-wall surfaces on an upstream side in a relative rotation direction of a housing with respect to a shaft, each of the lateral-wall surfaces having inclined surfaces inclined from the upstream side to a downstream side in the relative rotation direction of the housing from the projection parttoward the lateral surfaces of the seal ring.

A seal ring capable of stabilizing sealing performance while reducing rotation torque. A seal ringhas a plurality of first dynamic pressure generation grooveand a plurality of second dynamic pressure generation grooveon an outer peripheral surface thereof with intervals in the circumferential direction, the plurality of first dynamic pressure generation grooveextending from a position close to a first side surfaceA with respect to the center of width in an axial direction to the first side surfaceA and configured to generate dynamic pressure with relative rotation between a housing and the seal ring, and the plurality of second dynamic pressure generation grooveextending from a position close to a second side surfaceB with respect to the center of width in the axial direction to the second side surfaceB and configured to generate dynamic pressure with the relative rotation between the housing and the seal ring

A decoration panel used as an operation button includes a decoration section between a front translucent member and a rear translucent member, and the decoration section includes a counter reflection layer superposed on a rear face of a light-shield layer. A rear reflection layer is provided between the rear translucent member and a translucent member for illumination. The decoration section is displayed as if floating at an intermediate position in a depth direction. In addition, a surface of the decoration section oriented to the rear side constitutes a counter reflection surface.

A speaker in the present disclosure includes a magnetic circuit having a magnetic gap, a frame fixed to the magnetic circuit, a voice coil disposed in the magnetic gap, a cylindrical bobbin around which the voice coil is formed, and a diaphragm configured so that the inner circumferential side of the diaphragm is fixed to the bobbin and the outer edge of the diaphragm is supported by the frame with an edge member intervening therebetween. The diaphragm has an elliptical shape that is non-axisymmetric with respect to a center axis passing through the center of the bobbin. The diaphragm is formed by vacuum molding of a sheet-like raw material (thermoplastic CFRP sheet) in which long-fiber fillers are oriented in one direction in a thermoplastic resin. The orientation of the long-fiber fillers is set so as to match the short-axis direction of the diaphragm.

A seal ring capable of stably reducing a rotational torque while preventing the leakage of sealed fluid. The seal ring includes: an abutment joint part () provided at one portion in a circumferential direction thereof; a plurality of dynamic pressure generation grooves () provided at intervals in the circumferential direction on a side of a sliding surface thereof sliding on a lateral wall surface of an annular groove; and foreign matter discharging grooves () that are provided between a region in which the plurality of dynamic pressure generation grooves () is arranged and the abutment joint part () in the circumferential direction on the side of the sliding surface sliding on the lateral wall surface, and that are capable of catching foreign matter intruding from the abutment joint part () and discharging the caught foreign matter to an outside of a sliding part between the seal ring and the lateral wall surface.

A touch sensor module is structured by laminating an organic EL layer and a smoked glass layer on a substrate, which has a positive electrode pattern and a negative electrode pattern on the upper surface. When a driving voltage is applied to the positive electrode pattern, a current flows in a segment between the positive electrode pattern and the negative electrode pattern in the organic EL layer and the segment emits light. The emitted light causes a figure that represents a key to appear on the display surface of the touch sensor module. When the user touches a portion in which the figure representing a key is displayed on the display surface of the touch sensor module, a capacitance between the positive electrode pattern and the negative electrode pattern changes. Accordingly, the user's touch to the figure representing a key is detected.

Touch sensor and information processing system

The sealing device includes: an outer peripheral ringthat is in contact with a side wall surface of an annular grooveat a low pressure side (L), and slides with respect to an inner peripheral surface of a shaft hole in a housingthrough which a shaftis inserted. An inner peripheral ringmade of a rubber-like elastic body that is in contact with an inner peripheral surface of the outer peripheral ringand a groove bottom surface of the annular groove, respectively. The outer peripheral ringis formed on its outer peripheral surface with a concave portionwhich extends from an end of a high pressure side (H) to a position which does not arrive at an end of a low pressure side, so as to introduce fluid thereinto from the high pressure side.
