Abstract: Switches SW1 to SW4 and variable resistors are formed so as to overlap each other at positions corresponding to the X-axial positive direction, the X-axial negative direction, the Y-axial positive direction, and the Y-axial negative direction, respectively. When at least one of the switches SW1 to SW4 is off, no Z-axial output is activated and only X- and Y-axial outputs are activated. On the other hand, when any of the switches SW1 to SW4 is on, no X- and Y-axial outputs are activated and only a Z-axial output is activated.

Abstract: In paper and board machines the position of a rolling device relative to another rolling device and/or the force exerted by the rolling device on the other rolling device or any variable acting on these is measured, and the value of the measured variable is compared with the set value of said variable in order to obtain the difference value of the variable, and the position of the rolling device and/or the force it exerts on the other rolling device is controlled on the basis of the difference value. The fluid pressure of the hydraulic means (5) and/or the flow velocity of the fluid to the hydraulic means is changed in order to alter the difference value of the variable by opening and/or closing at least one digital valve in a digital valve pack (7) functionally connected to the hydraulic means (S).

Abstract: The present invention is based on the recognition that some materials contain a magnetically susceptible or magnetic component. That is, they exhibit ferromagnetic, paramagnetic, diamagnetic or magnetic properties. According to the invention, it is possible to determine the presence of a magnetically susceptible or magnetic component in a sample of a material by obtaining a sample of the material, positioning the sample at a predetermined distance from a magnet and then measuring the magnetic force on the sample by the magnet. The force is measured using a force transducer. To obtain the magnetic force per unit gravitational force, the gravitational force on the sample is measured out of the presence of the magnet and the measured magnetic force is then divided by the gravitational force exerted on the sample. A sample thickness adjustment is necessary if comparing samples of different thicknesses.

Abstract: A seat belt tension sensor assembly is adapted to be secured to the seat belt assembly of a vehicle. The assembly includes a housing for a seat belt anchor adapted for movement relative to the housing into an overload position where a portion of the anchor is abutted against a portion of the housing to limit and arrest the movement of the anchor relative to the housing and transfer the load from the anchor to the housing and then to an interior structure of the vehicle. In one embodiment, the housing forms a collar and the anchor includes an interior wall defining an aperture through which the collar extends when the anchor is mounted to the housing. Movement of the anchor relative to the housing is limited as a result of the contact between the interior anchor wall and the collar.

Abstract: Forces and moments are detected in a distinguishing manner by a simple structure. A supporting member (20) is positioned below a force receiving member (10), which receives forces to be detected, and between these components, four columnar force transmitting members (11 to 14) are connected. Connecting members, having flexibility, are interposed at the upper and lower ends of each of the columnar force transmitting members (11 to 14) so that the columnar force transmitting members (11 to 14) can become inclined when the force receiving member (10) becomes displaced upon receiving a force. Sensors (21 to 24), each equipped with capacitance elements, are positioned at the connections parts of the respective columnar force transmitting members (11 to 14) and the supporting member (20) to detect forces that are transmitted from the respective columnar force transmitting members (11 to 14) to the supporting member (20).

Abstract: A testing apparatus and method for determining the impact an/or vibration absorbent characteristics of an impact and/or vibration absorbent material. The apparatus includes a base having upwardly extending vertical guide rods. A sample plate is maintained in a position above the base by one or more springs of known spring rate. A weight is adapted to move vertically along the guide rods and to impact the sample plate and a sample of impact and/or vibration absorbent material when dropped from a raised position. The impact of the weight causes a downward vertical displacement of the sample plate, which displacement is measured by a moveable indicator. This displacement can be used, along with the total spring rate provided by the spring(s), to calculate a pass-through impact force. The pass-through impact force can then be subtracted from the impact force generated by the falling weight to determine the amount of impact force absorbed by the impact and/or vibration absorbent material.

The processing means comprises a rotation detecting unit for determining the speed of rotation of the rotation-side raceway member 4 from the number of repetitions of a variation in the output of the magnetostrictive sensor 8, a unit for averaging output values of the magnetostrictive sensor 8 and a load calculating unit for determining the load acting on an antifriction bearing from the output averaged by the averaging unit.

Abstract: A sealing valve 28 that controls a communication state between a fuel tank 10 and a canister 26 is provided. During stop of an internal combustion engine, the sealing valve 28 is generally closed, and the canister 26 is opened to the atmosphere. The sealing valve 28 is opened when the internal combustion engine is stopped, and differential pressure exceeding a valve opening determination value is generated between tank internal pressure and atmospheric pressure. A change in the tank internal pressure generated between before and after the sealing valve 28 is opened is detected. When the change in the tank internal pressure is below a predetermined determination value, closing failure of the sealing valve is determined.

Abstract: A testing apparatus having four-bar linkages pivotable to sleeves on opposite vertices with the sleeves of each vertex rotationally attached to each other. Links of each linkage are pivotally attached to loading plate assemblies securing a test specimen.

A pressure system fluidly impacts opposite faces of a piston of the assembly such that one of the faces is pressurized and impacts arms of the assembly for a sliding motion to move toward or away from the longitudinal axis of the apparatus thereby, applying a compression or tensile load on the specimen or augmenting the loads applied by the movement of the loading plate assemblies. The pressure system includes a controller connected to a reservoir, a pressurized source, a plurality of shutoff valves and pressure-adjustable check valves.
