US Patent:

46505458, Mar 17, 1987

Filed:

Feb 19, 1985

Appl. No.:

6/703066

Inventors:

Carl W. Laakso - Portland OR
John J. Reagan - Beaverton OR
Robert L. Beckman - Beaverton OR

Assignee:

Tektronix, Inc. - Beaverton OR

International Classification:

C23F 100
C23F 102
B44C 122
B29C 3700

US Classification:

156655

Abstract:

A polyimide embedded conductor process assures adherence of a metal conductor to a polyimide layer and allows closer spacing between conductors. The conductor is laid on a sacrificial substrate, and then the polyimide layer is laid over the conductor and substrate. The substrate is etched away to expose the conductor, and the polyimide layer may be etched away from the conductor to form attachment tabs.

International Classification:

H02G 1504

US Classification:

174 74R

Abstract:

A cable assembly (8, 80) including an electrical cable (10) having a flexible tubular jacket (12) and a reinforcing structure (14) attached to the outside of the jacket in a smooth sealing connection (30), and a method of using radio-frequency electrical energy, applied radially through the cable jacket (12) and the reinforcing structure (14), to make the connection (30). A shield conductor (26) inside the cable jacket (14) may be used as an RF electrode, with a second RF electrode (42, 44) circumscribing a portion of the cable (12) and the reinforcing structure (14) and shaping the outer surface of the connection. The RF energy may be used instead to activate an adhesive (108). An outer electrode (118) may be embedded in the reinforcing structure (116) in one variation of the invention.

International Classification:

B32B 300
B32B 900

US Classification:

428209

Abstract:

A pattern of conductive material is formed on a substrate of dielectric material. The substrate comprises a layer of flexible dielectric material having a layer of dimensionally-stable material adhered to one main face. The pattern is formed on the opposite main face of the layer of flexible dielectric material.

Robert Lee Beckman - Beaverton OR, US
Iver Skye Olsen - Portland OR, US

International Classification:

D07B 1/16
C09D 183/04

Abstract:

A silicone cable jacket and a cable assembly formed therefrom exhibits lubricious properties. The silicone cable jacket includes a silicone elastomer and a PSQ additive. The PSQ additive is selected as a polyalkylsilsesquioxane, a polyarylsilsesquioxane, a polyalkylaryl-silsesquioxane, or a mixture thereof. The silicone cable jacket exhibits a lower static and dynamic coefficient of friction (COF) as measured according to ASTM D 1894-14 and an enhanced level of abrasion resistance in a DIN 53516 test as compared to a similar cable jacket without the PSQ additive.
