IPC: G03F7/38
Filed: 1989-04-12
Abstract: PURPOSE:To reduce the difference between the pattern of the photoresist and that of the material to be etched by etching by silylating the photoresist formed into a pattern and hardening it to convert it into the resist containing SiO2.

Abstract: PURPOSE:To prevent the fusion of fibers during the infusibilization process and improve both the flexibility and the bundlability. CONSTITUTION:In a method for producing a carbon fiber by melt-spinning an optically anisotropic pitch, doubling the resultant pitch fibers, subsequently infusibilizing it, preliminarily carbonizing it and carbonizing or graphitizing it, a tension is applied through plural rollers to a bundle of spun pitch fibers and the resultant bundles of the spun pitch fibers are doubled through a doubling roller into a bundle of 500 to 10000 filaments while applying a heat-resistant fiber size. The resultant bundles each composed of 500 to 10000 filaments are intertwisted with each other while opening the bundle of the filaments by opening rollers. Further, a heat-resistant oily fiber size is applied thereto and the pitch fibers are bundled. The pitch fibers are subsequently infusibilized in an oxygen-containing atmosphere, then preliminarily carbonized in an inert atmosphere and subjected to carbonization or graphitization. The applied tension between open rollers to the fiber bundle is controlled to 5 to 150g/1000 filaments. The open rollers have each a cylindrical front plate shape and the curvature radius of the surface is 10 to 200mm. The pitch fibers are allowed to pass through three or more opening rollers.

Title: Electrode plate for fuel cell
Inventor: ENOMOTO KENJI
IPC: H01M4/96
Filed: 1981-06-19
Abstract: PURPOSE:To obtain an electrode plate for a fuel cell which has a low electric resistance by arranging carbon fibers so that their longitudinal direction corresponds to the current feeding direction so as to reduce the number of contacts between the said carbon fibers, and at the same time, by appropriately selecting the length of the said carbon fibers. CONSTITUTION:After a dispersed solution is prepared by appropriately dispersing carbon fibers having a length larger than the thickness of a current collecting part, the solution is filtered through a filter made of a metallic stainless-steel net with about 150 mesh so as to form a mat-like carbon fiber sheet over the filter. When the above filtration is performed at an increased speed by use of a vacuum pump, carbon fibers deposit on the filter, along the direction of the filtration, into mat-like form. In thus made electrode plate for a fuel cell, the direction of the carbon fibers of the current collecting part is maintained as it was during the filtration. As a result, the electric resistance of the electrode plate equals a resistance 4 of the carbon fibers themselves as indicated in the equivalent resistance in the figure, and the contact resistance of the electrode plate can be widely reduced.
