A method for alteration of the morphology of cellulose fibers, particularly softwood fibers, by (a) subjecting the fibers to a metal ion-activated peroxide treatment carried out at a pH of between about 1 and about 9, preferably between 3 and 7, and (b) subjecting the treated fibers to a refining treatment thereby converts SW fibers to HW-like fibers in many respects. The metal ion-activated peroxide treatment has been noted to act on pulp cellulose and hemi-cellulose, causing oxidation and oxidative degradation of cellulose fibers. The chemical treatment of the pulp, taken alone, is not sufficient to attain the desired modification of the morphology of the fibers, however, subsequent refining or like mechanical treatment of the chemically-treated fibers to achieve a given degree of refinement of the fibers requires dramatically less refining energy to achieve a desired end point of refinement and to impart other desirable properties to the pulp. A pulp of modified SW fibers and a mixture of HW fibers and modified HW fibers are disclosed.

To provide a system for processing program information in which the display structure of a program table can freely be changed in accordance with a requirement or a taste of an audience, the system for processing program information is constructed to include program information storage means 1 for storing program information, and program table display means 4 for two-dimensionally displaying a program table following two axes in accordance with two attributes 102 and 103 among attributes given to each piece of program information, to make the program table 101 for two-dimensionally displaying programs with two axes of free attributes. For the audience, program tables of various constructions can be displayed on the display means at will and in respective program retrieval operations, the program table easy to look for a program can be obtained. An objective program can be found in a short time by coming up with ideas for the extraction of the program or the like, and this is useful for making a broadcast view plan of himself.

In a storage apparatus for a vehicle including a lid which can rotate about a pivot, and a damper device having a cord-like connecting member and adapted to generate damping force against pulling force from the connecting member, wherein a connecting wire (the connecting member) is pulled, when the lid rotates in one direction, thereby to generate the damping force in the damper device, it is so constructed that a damping force control member having a guide face for the connecting wire is fixed to the lid, and when the lid has rotated in a direction of receiving the damping force, the connecting wire is wound around the guide face and pulled.

The invention discloses a preparation method for low basis weight newsprint by using 100% de-inking waste paper pulp added with retention and filter aid, which comprises a plurality of steps: add 100% de-inking waste paper pulp into a proportioning tank of a high-speed paper machine; then add calcium carbonate and fixing cation modified polyamines; add starch at the entrance of a machine chest; use tray water to flush the pulp at the outlet of the machine chest; control the wite pulp concentration at 1.0%; after desanding and deaerating, add the retention aid cation water soluble macromolecule polyacrylamide derivative at the outlet of a sizing pump and the inlet of a vertical screen; add filter aid polyethylenimine at the outlet of the vertical screen; the pulp is sent into a head box ofthe high-speed paper machine; thus, the low basis weight newsprint can be produced. The preparation method for low basis weight newsprint by using 100% de-inking waste paper pulp added with retentionand filter aid has the advantages that by adopting 100% de-inking waste paper pulp, the preparation method saves fiber material for making paper on the basis of changing the material structure of thenewsprint, greatly reducing the consumption of timber, water and electricity and the emission of pollutant, relieving the environmental pollution and lowering the production cost.

The invention relates to natural-color straw pulp with improved color phase, bulk and freeness and stable performance, in particular to natural-color straw pulp and application thereof in mixed pulp and paper products. The straw pulp has the advantages that: color phase or whiteness of the straw pulp is remarkably improved; the bulk and freeness are high; and the acquired data of the sizing agentof the natural-color straw pulp is more stable because of small quality fluctuation of sizing agent.
