Abstract: A cylinder head gasket 1 includes a shim ring 5 which surrounds a combustion chamber opening 2A in a gasket body 2. The shim ring is circumferentially spot welded along weld lines 5a, 5b. The weld spacing of the spot welding is varied to provide zones H.sub.1, H.sub.2 and H.sub.3 of high welding density and zone of a low welding density. The weld spacing in the zone of high welding density is such that a distortion in the shim ring is produced under the influence of heat generated during the welding operation if the weld spacing is used around the full circumference of the shim ring for spot welding. However, by interposing a zone of a low welding density, a distortion in the shim ring can be prevented while increasing the welding strength.

Abstract: A superconducting-coil apparatus according to the present invention comprises a normal-fluid helium bath, a superfluid helium bath, a channel connecting the two baths, superconducting coils contained in the superfluid helium bath, current lead wires extending from an exciting current source to the superconducting coils, through the channel, and a valve plug normally closing the channel and adapted to open the channel when the pressure inside the superfluid helium bath rises above a predetermined level. If the superconducting coils undergo quenching while they are being excited, the superfluid helium is gasified by Joule heat, produced in the coils. As a result, the pressure inside the superfluid helium bath increases, so that the valve plug is urged to open the channel due to the pressure difference. The gasified helium directly cools those portions of the lead wires which pass through the channel, thus these wire portions are prevented from being burned out.
