摘要:
Drive shafts having helical blades and methods of making are disclosed. In one method a helical auger blade is formed by twisting or sculpting a heated polymer tube which has been placed over a cylindrical drive shaft. In another method a drive shaft is placed within a helical winding and heat is applied to melt polymer which has been coated over one or both of the drive shaft and helical winding.

The present invention relates to a stringer, i.e., to a stiffening and structural longitudinal element for skin of aircraft airfoil surfaces, characterized in that it incorporates two separate and independent reinforcement areas, one in the foot and the other at the end of the web (head) of the stringer, where said reinforcement areas are obtained by means of a widening of the section of the stringer, said widening being formed by a localized stack of reinforcing plies of composite material which are embedded within the stringer. The invention also relates to the method of manufacture and is particularly applicable to stringers having an L-shaped or T-shaped section.

A flexible substrate, a display device and a method for bonding an electronic device onto a flexible substrate are disclosed. The flexible substrate comprises a base substrate (1), the base substrate (1) comprises a bonding portion (11) for bonding an electronic device and an auxiliary bonding (12, 121, 122) portion integrally formed with the bonding portion (11), the auxiliary bonding portion (12, 121, 122) and the bonding portion (11) are disposed back to back, and the bonding portion (11) completely falls into a region where the auxiliary bonding portion (12, 121, 122) is provided in an orthographic projection direction. With an auxiliary bonding portion (12, 121, 122) being disposed beside the bonding portion (11) for bonding the electronic devices such as ICs and FPCs, when bonding the electronic device onto the bonding portion (11), the auxiliary bonding portion (12, 121, 122) can enhance the strength of the bonding portion (11) and improve the bonding alignment precision and contact property of the electronic device, which further improves the non-defect ratio of the flexible display device and has a lower cost.
