Abstract:
To provide a porous polytetrafluoroethylene sheet which has excellent cold flow resistance and is used suitably for gaskets and a highly densified polytetrafluoroethylene sheet which has high tensile strength and flex life and is used suitably for diaphragms. The porous polytetrafluoroethylene sheet is produced from a polytetrafluoroethylene material having a microstructure of nodes interconnected by fibrils and has MTS of from 3,000 to 12,000 psi and C.I. of 0.02 to 0.20 g/cc/psi. The highly densified polytetrafluoroethylene sheet is produced by compression-molding the porous polytetrafluoroethylene sheet and then sintering completely. The porous polytetrafluoroethylene sheet is also laminated with a sheet of other material to provide a composite polytetrafluoroethylene molded article.

Abstract:
A peripheral docketing module using a shape memory alloy actuator wire includes a shape memory alloy actuator wire controllably connected to an energy source; and a pivoting device mounted inside a system frame member architecturally positioned for occupying inside the system frame member together with a device docketed within the system frame member. Upon application of energy to the shape memory alloy actuator wire, the shape memory alloy actuator wire contracts and exerts a pulling force on the pivoting device. The result is that the pivoting device pushes and ejects the docketed device seated inside the system frame member. The employment of a shape memory alloy actuator wire replaces the employments of a solenoid and electrical motor and allows for a more compact design of an electronic system.
Abstract:
A collpasible settee having a plurality of seats which are foldable into a smaller number of seats, comprising a rectangular settee frame having a substantial frame for two collapsible seat frames; both ends of the settee frame are connected to a conventional permanently upholstered frame; a crook groove is formed on each of two end walls of the settee frame at a side facing each other; two crook grooves are provided on a central wall; three longitudinal guiding blocks having channels are disposed on the settee frame; a runner longitudinally slidable on the channel is formed on each guiding block; two collapsible seat frames are disposed in two distinct interior sections of the settee frame; each collapsible seat frame has a shaft slidably received by the crook groove, a main frame, a foot-rest panel, and a back panel; and the settee is collapsible with the collapsible seat frames collapsed into folded state, the both end conventional parts of the settee are folded by sliding each end part in a direction toward the central wall, the two end parts are capable of sliding on the longitudinal guiding blocks and reaching each other at a location with respect to the central wall.
