A magnetic device which is highly durable, reliable, and safe without being damaged when a magnetic filed is applied. The magnetic device includes a cooling device having a cold head refrigerated by an effect of a cryogenic refrigerator, a magnetic field generation device configured to apply a non-stationary magnetic field on a magnetic body, and a cold head extension portion configured to thermally connect the magnetic body and the cold head. The cold head extension portion includes at least two members, one a low resistance member and the other a high resistance member having different resistivities. With this device, the eddy current generated in the cold head extension portion and the electromagnetic force produced in the cold head by the cold head extension portion are reduced.

A single-chip microcomputer comprising: a first bus having a central processing unit and a cache memory connected therewith; a second bus having a dynamic memory access control circuit and an external bus interface connected therewith; a break controller for connecting the first bus and the second bus selectively; a third bus having a peripheral module connected therewith and having a lower-speed bus cycle than the bus cycles of the first and second buses; and a bus state controller for effecting a data transfer and a synchronization between the second bus and the third bus. The single-chip microcomputer has the three divided internal buses to reduce the load capacity upon the signal transmission paths so that the signal transmission can be accomplished at a high speed. Moreover, the peripheral module required to have no operation speed is isolated so that the power dissipation can be reduced.

A superconductive ceramic composite material with high strength and capable of plastic deformation is prepared by mixing and sintering a superconductive powder represented by (RE.sub.x AE.sub.1-x).sub.1-y Cu.sub.y O.sub.z (RE represents Y or a rare-earth element having an atomic number of 57-71, or a combination of at least two of these elements, AE is at least one of alkaline earth elements Ca, Sr and Ba, x is 0.13-0.67, y is 0.25-0.67, and z is 1.08-1.17) and a metal powder M (M represents at least one of noble metals Rh, Pd, Ag, Ir, Pt and Au), in a defined ratio. The deformation (e.g., rolling) is followed by reheat-treatment (resintering). The powder mixture can be enclosed in a metallic capsule or made into a clad sheet by interposing the powder within two metallic sheets, and deformed (drawn or press formed into a desired shape) followed by sintering. The composite material may contain a superconductive network of such grains.

A connecting mechanism for a connector, which can align the connector in a rotating direction and smoothly align the connector for fitting with the mating connector, has a bracket, a holder, a connector and a plate. The bracket has a receiving body receiving the holder, and receives the holder in a receiving hole arranged in the receiving body. The receiving hole has an abut rib projecting from an inner surface in a radial direction. The holder receives the connector 4 and has an elastically deformable first positioning arm. When the holder is received in the receiving hole and fixed in the receiving body with the plate, the abut rib abuts on the first positioning arm, and the holder is aligned in a rotating direction about the receiving body.
