摘要： A bimetal is disclosed having a high, rapid deflection over a specified temperature range, including a high expansion metal alloy component having a high thermal expansion coefficient that changes rapidly at 50.times.10.sup.-6 /.degree. C. or greater at a temperature of between about 100.degree. C. and 250.degree. C. and containing from 15-30% by weight of manganese, the balance of iron. The second component has a substantially constant thermal expansion coefficient regardless of the temperature change, and is preferably a stainless steel. These bimetals are used in circuit breakers, thermal protectors and the like.

摘要： A dispersion strengthened copper alloy containing a copper matrix, and dispersion particles dispersed in the copper matrix within a range of 0.5 to 6 vol %. In this alloy, an average diameter of a matrix region where the dispersion particles are not present is 0.3 .mu.m or less, and the total amount of solid solution elements contained in the copper matrix is determined such that, when this amount of the solid solution elements is added to pure copper, the electric conductivity of the matrix is lowered by 5% IACS or less.

摘要： A control rod to be arranged in a nuclear reactor core comprises a body of a control rod, control rod guide rollers, pins connected to the guide rollers, and fixing members directly welded to the body of the control rod. The pins slidably support the respective guide rollers and the fixing members are engaged with the pins with a small clearance therebetween so as not to transfer welding heat from the fixing member to the pin.
