Display device and method of fabricating the same
InactiveUS20050070038A1Reduce weightAvoid stress concentrationSolid-state devicesSemiconductor/solid-state device manufacturingDriver circuitLiquid-crystal display
A method of fabricating a driver circuit for use with a passive matrix or active matrix electrooptical display device such as a liquid crystal display. The driver circuit occupies less space than heretofore. A circuit (stick crystal) having a length substantially equal to the length of one side of the matrix of the display device is used as the driver circuit. The circuit is bonded to one substrate of the display device, and then the terminals of the circuit are connected with the terminals of the display device. Subsequently, the substrate of the driver circuit is removed. This makes the configuration of the circuit much simpler than the configuration of the circuit heretofore required by the TAB method or COG method, because conducting lines are not laid in a complex manner. The driver circuit can be formed on a large-area substrate such as a glass substrate. The display device can be formed on a lightweight material having a high shock resistance such as a plastic substrate. Hence, a display device having excellent portability can be obtained.

Spring Clutch
InactiveUS20070240964A1Increases percentage of absorptionImprove rigidityFriction clutchesFreewheel clutchesStress concentrationTorque transmission
A spring clutch is provided which has improved durability by preventing a clutch spring from breaking due to fatigue. A cylindrical clutch spring made from a wire having a square section is mounted between a pulley and a pulley hub mounted in the pulley. An end of the clutch spring is coupled to the pulley hub. A clutch surface is formed on the inner periphery of the pulley and is formed with a large-diameter recess at a position opposite to the end portion of the clutch spring including the torque transmission end. When the pulley rotates in one direction, the clutch spring expands. At this time, the end portion of the clutch spring including the torque transmission end expands in the large-diameter recess, thus relaxing sharp torque produced in the clutch. This prevents local stress concentration on the clutch spring and breakage of the clutch spring and improves the durability of the clutch.

Spline Stress Distribution
InactiveUS20100303537A1Relieve pressureReduce stress concentrationYielding couplingRopes and cables for vehicles/pulleyStress distributionStress concentration
A connection between a shaft and a coupling that preferably involves involute shaped splines is designed to reduce stress from torque applied to the shaft by a drive motor. To avoid stress concentration at the mouth of the coupling on startup, the shaft splines are made to taper from the shaft end down to the spline end. As a result, the initial contact with the coupling splines occurs within the coupling and removed from it mouth. The shaft is allowed to elastically twist in response to the applied torque as the contact area increases with shaft twisting and the contact line moves toward the mouth of the coupling. Stress concentration that formerly occurred at the coupling mouth is alleviated as some shaft elastic twist occurs without adding stress to the shaft splines until coupling contact is made.
