摘要:
A cellulose solution having excellent fluidity and formability is prepared by dissolving a cellulose composition containing a component (I) of cellulose having a polymerization degree of 500 to 1000, and a component (II) of at least one member selected from celluloses having a polymerization degree corresponding to 90% of that of the component (I) cellulose and being in the range of from 350 to 900, cellulose derivatives and polysaccharides, the mixing ratio of the component (I) to the component (II) being 95:5 to 50:50, in a mixed solvent comprising N-methylmorpholine-N-oxide and another solvent material compatible with N-methylmorpholine-N-oxide but not capable of dissolving cellulose therein, and the resultant cellulose solution being useful for producing shaped articles, for example, fibers and films.

A cartridge is detachably mountable to an apparatus main assembly of an image forming apparatus. The cartridge includes a cartridge electrode formed on a frame. The cartridge electrode includes a first contact portion provided for being electrically connected to a main assembly contact of the apparatus main assembly and a second contact portion contacted to an electroconductive member. The cartridge electrode is integrally molded with the frame and further includes a portion that (i) is formed in a buffer portion and (ii) is formed from electroconductive resin.

When a user touches a tablet with a pen, a coordinate pointed with a nib of a pen and a tool force on this coordinate are detected, and a cursor is displayed at a position corresponding to the coordinate in a display device. Furthermore, the shape, color and size, etc., of the cursor can be varied according to a change in coordinate, tool force. This permits the user to recognize a level of the tool force which he actually applies at a glance. Additionally, an operational mode is switched according to an amount of change in detected coordinate and the tool force. As a result, the user is permitted to control an operational mode of the document processing device with ease only by a pen operation, thereby improving an operability.

A cartridge is provided with an electrode portion for connecting a main assembly contact. The cartridge electrode includes a first contact portion, exposed toward an outside of a frame of the cartridge, contacted to a main assembly contact provided in the apparatus main assembly. The cartridge electrode further includes a second contact portion provided for being electrically connected to a process means of the cartridge, and an injection receiving portion into which resin is injected when the cartridge electrode is molded into the frame. The electroconductive resin injected from the injection receiving portion is branched to mold the first contact portion and the second contact portion so that an electroconductive path for electrically connecting the main assembly contact and the process means is formed.

摘要:
The present invention relates to an acrylonitrile copolymer comprising 70% by weight or more of an acrylonitrile monomer unit and 0.1-30% by weight of a fluoroalkyl methacrylate or fluoroalkyl acrylate monomer unit and having an intrinsic viscosity of 0.8-10, as well as to an acrylonitrile type core-sheath conjugate fiber using the above copolymer as the sheath component. The copolymer according to the present invention has water repellency by itself; accordingly, the above conjugate fiber prepared therefrom also exhibits water repellency permanently.
