Title: Contact device
Inventor: MAEMURA NOBUTAKA
IPC: H01H31/02
Filed: 1999-04-02
Abstract: PROBLEM TO BE SOLVED: To provide a contact device capable of reducing the contact resistance of a current feed contact and increasing the current feed capacity without enlarging the device. SOLUTION: A projection 49 is provided on either of the periphery of a conductor and the contacting part of a contact piece while a groove 48 is formed in the other member, and the projection 49 is fitted in the groove 48 so that contact is generated at the two internal side faces of the groove 48, and thereby a contact force greater than the initial contact force is generated owing to the component of the contact force produced by contacting two contact points. Increase of the contact force decreases the electric resistance and increases the current feed capacity. In particular, the contact force can be made over double by arranging so that the angle of the intersecting point formed by two tangents on a plane perpendicular to the axis of the conductor at the two contact points, and it is possible to increase the current feed capacity to a great extent.

Title: Production of amorphous metal
Inventor: MURAKAMI SHIYOUJI
IPC: B22D11/06
Filed: 1980-07-15
Abstract: PURPOSE: To obtain a prescribed shape on the way of producing an amorphous metallic tape, and simplify process and improve productivity by coating a material of which the thermal conductivity is lower than that of a cooling body material on part of the surface of a cooling body.  
     CONSTITUTION: A low heat conductive material 7 of the heat conductivity sufficiently lower than that of a roll material is coated on part of the surface of the roll at right angle to the revolving direction of the roll, and the molten metal heated to melt by a melting and heating device 2 is ejected by gaseous pressure through a nozzle 4. The ejected molten metal is cooled extra quickly on the surface of a roll 5, but the rate of cooling is slower on the material 7 of sufficiently low heat conductivity than on the roll 5. Namely, if the rate of cooling is slower than the rate of cooling necessary for amorphous a substance it forms crystalline, and becomes weak and brittle in strength as compared to the amorphous part and this causes a tape 8 to be easily bent by the centrifugal forces parting from the surface of the roll 5, whereby the amorphous metallic tape 8 of a constant size is continuosly obtained.
