In an angular velocity sensor, there is generated a first parasitic capacitance generated between a first driving electrode and a sensing electrode, and there is generated a second parasitic capacitance generated between a second driving electrode and the sensing electrode. The ratio of the amplitude of a first drive signal to the amplitude of a second drive signal is set to the reciprocal of the ratio of the first parasitic capacitance to the second parasitic capacitance. This allows the noise contents generated by capacitive coupling to be efficiently offset, thereby improving detection accuracy of an angular velocity sensing signal.

A pneumatic tire comprises a tread portion, a pair of sidewall portions, a pair of bead portions, a carcass, a belt, and a reinforcing member arranged in a tire zone including at least the sidewall portion, wherein a shearing rigidity in the circumferential direction of the reinforcing member is made larger at a first tire zone located at an outside of the vehicle than at a second tire zone located at an inside of the vehicle in the same tire at a posture of mounting the tire onto a vehicle.

The device is a counterbalance system and method to reduce the work of conventionally balanced, reciprocating cantilevered beam pumping units, and comprises a pair of transversely oriented support mounts attached to the cantilevered beam or walking beam of a pre-existing reciprocating pumping unit, attaching on either side of the pivoting-fulcrum, mounting point of the cantilevered walking beam. These transverse mounting points terminate individually on either side of said walking beam in channel-like saddles that support independent, parallel beams, which in turn cantilever themselves in tandem with said walking beam of the pumping unit; moreover, the position of the parallel beams by virtue of the transverse mounts creates a new center of gravity corresponding to the center of the pivoting mounting point of the walking beam, eliminating counter-productive torque forces on the walking beam as it tilts from horizontal.

A magnetic sensor control device has an input section, a selection section, a calculation section, and a setting section. The input section inputs a plurality of magnetic data each having 3 components sequentially output from a 3-dimensional (3D) magnetic sensor. The selection section selects 4 magnetic data satisfying a predetermined 4-point selection condition from the plurality of the input magnetic data. The calculation section calculates a center point equally distant from 4 points corresponding to the 4 selected magnetic data. The setting section sets 3 components representing the center point as an offset of the magnetic data.

A highly retractable intravascular stent delivery system, including a tube assembly and a rotation driving assembly. The tube assembly includes an outer tube 5, an intermediate tube 6, and inner tube 7, wherein an intravascular stent 3 and a stent retaining block 4 are provided within the outer tube 5. The rotation driving assembly includes a housing 9, an outer screw 19, and an intermediate screw 14 located within the housing 9, as well as a driving member. The driving member allows two screws to rotate at opposite directions, so as to drive the outer tube 5 to move toward the proximal end, and the intermediate tube 6 pushes the stent retaining block 4 and the intravascular stent 3 to move toward the distal end. The system uses three-lay tube structure and uses driving gear to drive two screws to move at directions opposite to each other, such that the intermediate tube 6 and the outer tube 5 are driven to move to directions opposite to each other. Therefore, the axial retraction of the intravascular stents can be effectively offset and axial movement of the intravascular stents due to axial retraction of the intravascular stents is avoided, thereby accurately implanting the stents into the body.

A counterbalance system may include an outrigger support structure, a first elongated outrigger member, and a second elongated outrigger member. The outrigger support structure is adapted to be mounted in an operating position on a walking beam of a pumping unit. The first elongated outrigger member is connected to the outrigger support structure at a first lateral side of the counterbalance system. The second outrigger member is also connected to the outrigger support structure, but is connected at a second lateral side of the counterbalance system. A first suspension element may be connected to the first outrigger member and a second suspension element may be connected to the second outrigger member. Suitable counterbalance weights may be connected to the first suspension element while additional counterbalance weights may be connected to the second suspension element. These counterbalance weights connected to the first and second suspension elements may be used to counterbalance the weight on the downhole weight on the walking beam.

Disclosed is a rocker arm shaft for an automobile engine, which is effectively capable of offsetting the length change of the rocker arm shaft, which caused by heat. According to an embodiment of the present invention, a rocker arm shaft can be divided into at least two shafts. An elastic member, such as a coil spring, is positioned between the shafts. When the length change of the shafts is changed by heat, the elastic member offsets the changed length of the shafts. The rocker arm shaft is divided into a hollow first shaft and a hollow second shaft. A one end of the second shaft of the rocker arm shaft forms a receiving groove for inserting the elastic member. With this structure, the rocker arm shaft for an automobile engine does not bend nor get twisted by offsetting the changed length of the shafts by means of the elastic member.

A dishwasher incorporates a dampened pump assembly including a housing having a base to which is mounted a pump and motor unit configured to develop a flow of washing fluid during operation of the dishwasher. A mass damper is mounted to the housing, with the mass damper substantially conforming to the shape, directly abutting and being rigidly fixed to a portion of the housing at a position offset from the pump and motor unit. The mass damper provides added weight, generally in the order of 1-6 lbs, to the pump assembly which reduces vibrations throughout the dishwasher caused by operation of the pump and motor unit.

The present invention relates to a steering control apparatus and a steering control method for removing an inwardly caused disturbance or outwardly caused disturbance with respect to a vehicle. It is possible to efficiently remove a disturbance of a steering control apparatus which is generated due to various causes by: confirming a disturbance cause based on estimated frequencies estimated based on three factors that affect the steering control apparatus (i.e., a first estimated frequency estimated based on the estimation of a rack force, a second estimated frequency estimated based on a steering torque signal, and a third estimated frequency estimated based on a vehicle wheel rotational speed); then determining a compensation rate, which varies depending on whether the disturbance is an internally caused disturbance or an externally caused disturbance; and then applying the compensation rate to a steering current value.

A source driver and an operation method thereof are provided. The source driver includes a chopper circuit and a source driver circuit. A first sub-pixel and a second sub-pixel are temporally or spatially adjacent to each other. The chopper circuit adds original gray-scale data of the first sub-pixel with a first value to serve as new gray-scale data of the first sub-pixel and deducts original gray-scale data of the second sub-pixel by a second value to serve as new gray-scale data of the second sub-pixel. The source driver circuit generates a first driving voltage for the first sub-pixel according to the new gray-scale data of the first sub-pixel and generates a second driving voltage for the second sub-pixel according to the new gray-scale data of the second sub-pixel.
