摘要： PURPOSE:To provide a nonvolatile semiconductor memory device of high reliability which can surely avoid false recognition of data even if the number of rewritings is increased. CONSTITUTION:One memory cell is formed of two MOS transistors 30, 31 with floating gates 14, 15. In the two MOS transistors 30, 31, different logical levels are always input and output. If a pair of outputs obtained in this way are differentially amplified, false recognition of data caused by variation of threshold value of the MOS transistors 30, 31 can be avoided on judgment of '0', '1' of data of the memory cell.

摘要： PURPOSE:To obtain a wheel with high quality by shaping a strip of titanium to a pipe and forming a blank pipe by applying TIG welding, forming a rim use blank pipe by cutting it to desired length, and forming a rim by a rim forming working machine, thereafter, assembling it as a wheel. CONSTITUTION:From a strip 1 made of titanium (alloy), a blank pipe is shaped by a pipe shaping device (a) constituted of a forming roll 2 and a hydro-roll 3, etc. Subsequently, a butt part of the blank pipe is welded by a TIG welding machine 4, and by bringing it to cutting working to a necessary length, a rim use blank pipe 5 is formed. After forming and cooling, said pipe is carried into a multistage type rim forming working machine 6 installed in the next position of a flash butt or D.C but welding machine in a wheel manufacturing equipment A, and a rim R is formed. Next, by assembling a disk D and the rim R and painting them, a wheel W is obtained. In this regard, it is also allowed that the rim forming is facilitated by executing stress relief annealing after forming the blank pipe. In such a way, the blank pipe whose roundness is excellent is shaped, and a wheel of a high quality having a characteristic of a weld zone whose corrosion resistance, strength and fatigue characteristic are the same as those of a base metal can be obtained.
