IPC: B65H37/02
Filed: 2001-11-07
Abstract: PROBLEM TO BE SOLVED: To provide a binding method for a saddle stitched book, which has comparatively few pages such as about twenty pages or less and is efficiently bound by a pasting system at a low cost. SOLUTION: A sheet 2 having printing surfaces by four pages on obverse and reverse and at right and left is printed with a printing machine. Respective sheets are gathered by a gathering machine 1, successively fed out of the delivery port of the gathering machine in the order of numbers of pages without overlapping and leaving intervals therebetween. Next, the respective sheets are transferred so as to provide a chevron folding ridge 3 along a feeding-out direction at the middle between pages. During the transferring of the respective sheets, paste 16 is applied on the folds 3 of the respective sheets. Finally, by successively gathering the respective sheets on a saddle, a saddle stitching is realized through the pastes applied on the respective sheets.

Title: Projection display device
Inventor: KONISHI TAKAYA
IPC: H04N5/74
Filed: 2001-11-13
Abstract: PROBLEM TO BE SOLVED: To perform projections as if a speaker speaks to a party on a projection display device for video conference and to prevent an incorporated camera from disturbing image display. SOLUTION: A camera 5 photographs the speaker in the front through a small hole 4a on a screen.

Abstract: <P>PROBLEM TO BE SOLVED: To provide a seat belt capable of providing a characteristic approximate to a desired webbing elongation characteristic.  <P>SOLUTION: A webbing 10 has a structure in which three layers, namely an upper layer 11, an intermediate layer 12, and a lower layer 13, are stacked in the thickness direction. The upper layer 11 is plain-woven from warps 11A, the lower layer 13 is diagonally woven from warps 12A, and the intermediate layer 12 has no weft and has warps 12A arranged in a tension state in the elongation direction of the webbing 10. The webbing 10 thus has a structure of three layers having a different warp forming method, and loosenesses of the warps constituting respective layers are different from each other. Thus, when a tensile load is charged on the webbing, the layers come into the tension states sequentially from the layer having less looseness and receive the tensile loads. Therefore, the load-elongation characteristic of the webbing 10 can be changed gradually (step by step).  <P>COPYRIGHT: (C)2003,JPO
