Title: Manufacture of composite decorative sheet
Inventor: MAKI TETSUO
IPC: B27D5/00
Filed: 1989-06-26
Abstract: PURPOSE:To prevent simply the generation of warping by bonding a woody paper material by means of a bonding agent having good permeability and waterproofness after being cured on the rear surface side of a base, and then bonding a composite material on the rear surface side of said paper material. CONSTITUTION:A decorative veneer 2 is bonded on the surface side of a base 1, while a woody paper material 4 is bonded on the rear surface side by means of a bonding agent having good permeability and waterproofness after being cured. When said materials are dried, a warping of the base 1 generated by the shrinkage of the bonded decorative veneer 2 bonded on the surface side of the base 1 is offset by a warping generated by the shrinkage of said paper material 4 bonded on the rear surface side of the base 1. A composite material 3 is bonded on the rear surface side of said paper material 4 by means of a water-soluble emulsion bonding agent, and the permeation of the bonding agent into the rear surface side of the base 1 through the paper material 4 is prevented by the bonding agent permeated into the paper material 4 and cured therein. The rear surface side of the base 1 is expanded by said process to prevent a decorative composite sheet from warping.

Title: Corrosion-resistant alloy with high magnetic permeability
Inventor: HAGI CHITOSHI
IPC: H01F1/14
Filed: 1981-10-14
Abstract: PURPOSE:To improve the corrosion resistance of an Fe-Al-Si alloy without deteriorating the superior magnetic characteristics by combinedly adding A Pt group element and N2 or C to the Fe-Al-Si alloy. CONSTITUTION:This alloy consists of, by weight, 3-16% Si, 2.5-17% Al, 0.001-4.0% of >=1 kind of Pt group element, 5-1,000ppm N2 and/or 100- 2,000ppm C, and the balance chiefly Fe. Less then the lower limits of the Pt  group element, N2 and C do not distinctly produce the effect, and more than the  upper limits of them deteriorate remarkably the magnetic characteristics and  make the alloy impractical. By this method the wear resistance and machinability can be also improved. By further adding an adequate amount of an element  such as Ti or V as a secondary component, the corrosion resistance can be improved furthermore by the synergistic effect.

Title: Bottomed cylindrical body, its production and device therefor
Inventor: OKUBO KEIGO
IPC: H01M50/124
Filed: 1996-06-03
Abstract: PROBLEM TO BE SOLVED: To improve the adhesion of a metallic layer in a cylindrical body by forming the shape of the boundary face between the inside wall face and the metallic layer into a rugged one. SOLUTION: In a bottomed cylindrical body made of Al or the alloy thereof provided with an inside wall face and a metallic layer, the shape of the boundary face between the inside wall face and the metallic layer is formed into a rugged one. Concretely, tunnel pits 22 are formed by etching the inside wall face of the bottomed cylindrical body 20. Thus, by the tunnel pits 22, the contact area of plating remarkably increases. Furthermore, since the plating is precipitated into the tunnel pits 22, anchor effect is operated at this time to obtain the chromium plating layer, i.e., metallic layer 25 excellent in adhesion. As a result, the peeling of the metallic layer can be prevented even at a high temp. (about 400 deg.C).

Title: Controller for electric rolling stock
Inventor: HEGIHARA HIDEKI
IPC: B60L3/00
Filed: 1985-07-26
Abstract: PURPOSE:To protect an element and a circuit in a thyristor circuit by operating a filter capacitor discharging circuit on the detection of the voltage drop of a control power supply. CONSTITUTION:When the voltage of a control power supply 8 for a gate control circuit 7 is made lower than voltage where the normal operation of a gate circuit can be ensured during the working of an electric rolling stock, a voltage- drop detector 9 is operated, and a breaker 10 is opened while gate pulses are transmitted over the gate circuit 11. Consequently, the residual charges of a filter capacitor 4 are discharged by a time constant determined by a thyristor 13 for discharging the charges of the filter capacitor and a resistor 12. Even when the gate control circuit 7 applies defective gate pulses to a thyristor circuit 5 at that time, currents do not flow through the thyristor circuit 5, thus preventing the damage and trouble of a circuit in the thyristor circuit 5 and a thyristor element.
