Filed: 1997-09-26
Abstract: PROBLEM TO BE SOLVED: To prevent the weld crack of stainless steel irradiated with a high dose of neutrons by setting the welding condition so that no helium bubble may deposit on grain boundaries. SOLUTION: In a method for welding stainless steel irradiated with a high dose (>=10<18> n/cm<2> ) of neutrons, a hot ray, such as the electron beam, YAG laser beam, carbon dioxide laser beam, etc., having a low or high heat input density is used and the amount of welding heat input is set to <=0.04 kJ/mm<2> , and then, the cooling rate when the weld is cooled to 773 K from 1,273 K is set to >=738 K/sec. It is preferable to lower the amount of heat input by performing narrow scarf welding at the time of performing TIG welding.

Abstract: PROBLEM TO BE SOLVED: To prevent the deceleration of access speed and the collision of data between both the kinds of access when continuing write access after read access in the case of access from a high-speed CPU to a low-speed device. SOLUTION: When the logic level of a CE* terminal of a flash ROM 2 becomes L level in read access, as the low-speed device, the flash ROM 2 outputs read data soon. Before the logic level of CE* terminal becomes H level, a buffer 6 fetches the read data while a latch control signal BLTCH is at the H level, the output is immediately turned into high impedance and the access with the flash ROM 2 is finished. After the logic level of the CE* terminal is returned to H level and an output control signal BCON* becomes L level, the buffer 6 outputs the read data to a CPU bus 5. While the logic level of a READY* terminal is L level, the CPU 1 fetches these read data.
