Title: Manufacturing method of weatherproof overlay decorative board
Inventor: OOTA TOMOHISA
IPC: B44C3/02
Filed: 1978-05-08
Abstract: PURPOSE: To produce weatherproof overlay decorative board surfaced with thermoplastic film which improves uniformly the deterioration of the surface.  
     CONSTITUTION: Thermoplastic film with adhesive is pressed and sticked onto thin overlay board made of such timbers as walnut, rosewood, etc. and pretreated with an impregnant, to produce a overlay decorative board. In the process and ultraviolet absorbing agent (for example, 2,4-dihydroxybenzophenone) is included in the  impregnant. Desirable viscosity of the impregnant is in the range of 0.4W200 cps depending on the applying method, such as spray coating or roll painting. The emboss of the overlay board is generally about 100 μ. Ultraviolet absorbing agent improves the weather proofing but too much of it fills up the emboss and smoothes out the roughness of the product when thermoplastic film is sticked. Therefore, small quantity but effective ultraviolet absorbing agent is chosen and applied in the range of 0.01W10 g/m 2 .

Filed: 1995-03-14
Abstract: PURPOSE: To provide the high-performance solid-state magnetic recording element having a biporous pin switch structure and having a memory function and to obtain a solid-state magnetic recording element having high detection sensitivity and excellent controllability. CONSTITUTION: This solid-state magnetic recording element is constituted by laminating a first ferromagnetic metallic layer 2a, a second ferromagnetic metallic layer 2b and a nonmagnetic layer 3 interposed therebetween. The potential change from reference potential is induced in the second ferromagnetic metallic layer 2b by energization between the first ferromagnetic metallic layer 2a and the nonmagnetic layer 3. The polarities of this potential change varies when the directions of the magnetization of the first ferromagnetic metallic layer 2a and the second ferromagnetic metallic layer 2b are parallel or counter parallel arrangement. The uniaxial magnetic anisotropy within the film plane is thus imparted in the same direction on the first and second ferromagnetic metallic layers 2a, 2b.
