Filed: 1994-07-26
Abstract: PURPOSE:To shorten a test time in a test for discriminating existence of a memory cell causing over erasing, in a flash memory performing batch erasion. CONSTITUTION:A memory transistor of a defective memory cell being apt to cause over erasing is made to cause over erasing (step S1) by applying an erasing pulse plural times (e.g. 5 times) after blank check (step S10) without performing writing operation and erasing operation of actual data for each memory cell. In this state, a CB test for discriminating existence of a memory cell causing over erasing is performed (step S12).

Title: Colored optical parts and their production
Inventor: HOSHIYAMA SEIICHIRO
IPC: G02C7/10
Filed: 1994-07-26
Abstract: PURPOSE:To produce stably colored optical parts with good reproducibility by applying dyes on a base material surface, then subjecting the base material to nonuniform heating by irradiation with radiation heat or radiation energy, thereby imparting a coloration density gradient of the dyes to the base material surface. CONSTITUTION:The uniform coating film 3 of the dyes is formed on the surface to be colored of a lens base material 4. Next, the lens base material 4 on which the coating film 3 of the dyes is formed, is subjected to nonuniform heating in an IR lamp heating furnace 1 to impregnate the inside of the lens with the dyes by heating. Transmittance in visuality is higher as the distance from the end S is larger. Namely, the shielding time of the radiation heat by a shielding plate 2 is longer and the heating time is shorter as the distance from the end S on the lens base material 4 is larger. The coloration density is thus lighter in the part where the heating time is shorter and, therefore, the transmittance in visuality is higher. Namely, the colored optical parts having a desired density gradation patterns are easily obtd. by subjecting the lens base material to the nonuniform heating while controlling the heating in such a manner that the differences in heating quantity corresponding to the desired density gradient are obtd.
