Title: Stainless steel having excellent oxidation resistance and preparation thereof
Inventor: HOSOI YUUZOU
IPC: C22C38/00
Filed: 1983-03-12
Abstract: PURPOSE:To obtain stainless steel having excellent oxidation resistance and spalling resistance in a high temp. environment, by melting or heat treating the surface layer part of stainless steel by irradiating the surface thereof with laser beam. CONSTITUTION:Ferrite type or austenite type stainless steel is irradiated with laser beam pref. in an inert gaseous atmosphere such as Ar-gas or N2-gas and a molten or heat treated layer is formed to the surface layer part of the aforementioned stainless steel in a depth of 1mm. or less. In addition, when a thin stainless steel plate is treated as the object, the depth of the aforementioned surface layer part is set to 0.5mm. or less. In this case, because only the surface layer part of stainless steel may be modified, the irradiation time of laser beam is extremely short, for example, 1sec or less and oxidation or gas generation with the melting of stainless steel is reduced and a working environment is also well. When modified stainless steel is heated in an oxidative atmosphere, oxidation resistance and spalling resistance are extremely good.

Title: Flash erasable nonvolatie memory
Inventor: FUCHIGAMI KEISUKE
IPC: G11C17/00
Filed: 1993-03-03
Abstract: PURPOSE:To shorten time required for erasing operation, in the case where the existence of a memory cell with an erasing defect is confirmed, by starting a re-erasing and verifying operation from the address stored in a storage part. CONSTITUTION:When the threshold voltage of the cell area with erasing performed in a memory cell and a cell part 4 is lowered, a read-out confirmation whether the erasing is normally finished or not is performed by an erase comparator 5. An address to confirm the read-out is given to the cell part 4 by an internal address part 1; and by receiving this address, the selection of a cell 4 in the memory cell 4 is performed by a decoder part 3. Then, the address in the memory cell with the erasing defect is stored in a storage part 2 for the address with erasing defects. After that, a verifying operation besides erasing is started from the defective address stored in the storage part 2. Thus, the time for erasing operation including erasing and/or erasing and verifying is shortened.

Filed: 1986-02-28
Abstract: PURPOSE:To detect the coincidence of discrepancy between a frame pattern of input data and a frame pattern corresponding to a program, by using a prescribed bit in an address signal read-out, as a data for specifying a kind of a program executed by a CPU. CONSTITUTION:A CPU 1 outputs a chips select signal to an input use device 4 through a control signal line 9 and sets this device to an enable stage. The CPU 1 collates a frame pattern which an inputted data has and a frame pattern which has been read out in advance from a memory 2, and in case they have coincided, a program A in the memory 2 is executed, and in case they do not coincide, a program B is executed. At the same time, the uppermost 1 bit of a read-out address is inputted to a display means 16 through a signal line 15. The display means 16 displays a fact that the CPU 1 is executing the program B, because the input bit becomes '0' in this case. Accordingly, an external output use device can be omitted and a circuit of a system can be simplified.
