Title: Production of pressure-sensitive adhesive double coated tape
Inventor: HISHIDA MAKOTO
IPC: C09J133/00
Filed: 1994-07-05
Abstract: PURPOSE:To provide a process for producing a pressure-sensitive adhesive double coated tape using Japanese paper as a support, which provides rapid coating and high productivity and is suitable for applications where removability is required. CONSTITUTION:A pressure-sensitive adhesive layer formed of a resin is formed by transfer on both sides of Japanese paper impregnated with a resin.

IPC: H04R1/30
Filed: 1980-10-30
Abstract: PURPOSE: To make tone quality uniform without variance of sound pressure distribution due to frequencies, by permitting the side wall constituting a horn to be a prescribed curve.  
     CONSTITUTION: A horn is formed with four wall surfaces 1∼4, and when angles θH, θV toward horizontal and vertical directions are equal, a tangential angle of the side wall at horn aperture is set to 3 1/2 θ. Each side wall curve of the horn is represented with a function of a=a 0 (1+αX) n , where a 0  is the size of throat, (a) is size of cross-section of a distance X from the throat, α is a coefficient of spread (different from n 1  and n 2 ), and the value of (n) is n 1 (n 1 ≥2) at aperture side and n 2 (n 2 >n 1 ) at the throat side for coupled type. When the relation of the directional angles is θV<θH, a curve is taken so that the change of the cross-section at the side of the wall side having greater tangential angle 3 1/2 θ of the aperture of the throat horn becomes expotential.

But, scratches remain in the rolling direction. Then, the wet skin-pass rolling is performed by a skin- pass rolling mill 2b as the 2nd pass, the elongation coefficient ranges 0.2-0.8 to reduce scratches generated in the 1st pass. Thereby, the pit-like unevenness on the surface can be removed, the scratches, too, be reduced and high glossiness be obtained.
