Title: Manufacture of board for multi-layer printed wiring board
Inventor: AMANO SABURO
IPC: H05K3/46
Filed: 1988-03-03
Abstract: PURPOSE:To improve haloing and heat-resistance, by forming a circuit on a laminated plate coated with adhesive including plating catalyzer and then reducing the copper surface of it after chemically roughing the surface and by laminating a prepreg with plating catalyzer and an adhesive sheet with plating catalyzer by heat and pressure. CONSTITUTION:After forming a circuit by the additive process on a laminated plate coated with adhesive including plating catalyzer, the copper surface is made rough by chemicals and then is reduced. On top of it, prepreg with plating catalyzer and an adhesive sheet with plating catalyzer are piled up and are formed into one body by applying heat and pressure. Since the materials are adhered to each other after internal layer copper is previously made rough by chemicals and the surface is reduced, a good layer-to-layer adhesion is gained. Both the prepreg resin and the adhesive include plating catalyzer, so inner surfaces, including even very minute recesses, of through-holes are well coated with plating in cooperation with the effect of activation treatment. Therefore, plating can be conducted effectively with only a small penetration of activation fluids.

Title: Multiple layer magnetic material film adhesion type thin film magnetic head
Inventor: MURAKAMI YOICHI
IPC: G11B5/23
Filed: 1989-03-03
Abstract: PURPOSE:To improve the reproducing efficiency of a recording signal in a high frequency band area by reducing eddy current loss by adhering and forming multiple layers of magnetic material film separated interposing an electrical insulator, and setting the total film width of the magnetic material film width of each layer almost equal to magnetic material film width corresponding to track width. CONSTITUTION:'Sendust(R)' films 5' and 5'' are adhered and formed obliquely at a prescribed angle theta against an R/W gap 3, and each film is provided with film width l2 and is insulated and separated electrically interposing the electrical insulator 7. The width of the electrical insulator 7 is formed remarkably thin, and the film width totaling each film width l2 of the 'Sendust(R)' films 5' and 5'' are formed almost equal to the prescribed film width corresponding to the track width L. In other words, it is 2l2Lsin theta in this example, and each film width l2 of the 'Sendust(R)' films 5' and 5'' is reduced to around 1/2 of the film width l2 of a conventional 'Sendust(R)' film 5(l2approx.=l1/2). Thus, by setting the film width l2 of the 'Sendust(R)' films 5' and 5'' at prescribed width, the reproducing efficiency of the recoding signal can be prevented from being deteriorated in the high frequency band area by reducing the eddy current loss.

Title: Separation of arsenic container in smelting intermediate material and recovering method of arsenic
Inventor: TAKEBAYASHI KAZUAKI
IPC: C01G28/02
Filed: 1996-03-08
Abstract: PROBLEM TO BE SOLVED: To increase the exudation rate of arsenic and to improve the exudation ratio by adding a copper compound in a raw material slurry to exude and separate arsenic in a solution. SOLUTION: The raw material slurry is prepared by adding water to the smelting intermediate material containing arsenic and charged in a reactor with the addition of the copper compound such as an electrolytic sediment copper. Next, the reaction is proceeded by blowing air at a proper rate while controlling pH to 6.5-7.5 by adding a NaOH aq. solution and the temp. to 60-90 deg.C. After that, the slurry is filtered to be separated into a copper-containing residue and the solution. Calcium hydroxide is added in the resultant solution to recover calcium arsenate having a stable form. In such a case, the addition of the copper compound is by the following reason. The copper compound reacts with arsenic sulfide to be converted to copper sulfide and arsenic is oxidized into arsenous acid.  Since the formation of arsenous acid is accelerated by the reaction, the reaction time is reduced and the exudation ratio is improved.
