    摘要: Disclosed is a semiconductor memory device capable of arbitrarily setting an upper limit of the number of error corrections during a test operation. The semiconductor memory device has a counter, a register, and a comparison circuit. The counter counts the number of error corrections. The register, when an upper limit setting signal (in the case shown in FIG. 1, an external upper limit fetch signal) is externally inputted to change the upper limit of the number of error corrections, changes the upper limit. The comparison circuit compares the number of error corrections with the changed upper limit.

    摘要: An address switch circuit receives a row address signal supplied to a first address terminal group and a column address signal supplied to a second address terminal group. Further, the address switch circuit receives the row address signal supplied to the second address terminal group and thereafter receives the column address signal supplied to the second address terminal group and supplies the received row address signal and the received column address signal to the row decoder and the column decoder during a second operation mode. The number of semiconductor memories that are tested at once can be increased by executing an operation test of the semiconductor memories in the second operation mode. In addition, it becomes possible to test a semiconductor memory using test assets for other semiconductor memories. Consequently, the test efficiency can be improved, and the test cost can be reduced.

    摘要: A pipe for supplying a dope to a co-casting die consists of a goose neck portion connected to a feed block of the co-casting die, and a straight pipe portion connected to the goose neck portion. The goose neck portion has a radius of curvature of 50 mm to 400 mm, and the straight pipe portion forms an angle of 0 to 20 degrees to the horizontal plane. Venting valves are opened up at the beginning of dope feeding, and are closed to some extent as the dope comes out. After the air is completely vented out, the venting valves are completely closed. Thereby, an air collection is completely let out from the pipe, a plastic web discharged from die lips of the co-casting die would not contain any air bubbles, it is prevented that the web splashes to put on the die lips, causing streaks on the produced film.

    摘要: A cellulose acetate solution is filtrated with a filter medium formed of cellulose fiber. Hydroxyl groups on the filter medium are substituted to other functional groups. An acidic material is added to the cellulose acetate solution, and the filtration is preformed. In order to estimate the hydrogen ion concentration of the organic solvent, a sample solvent of thereof is mixed with water so as to transport hydrogen ions from the sample solvent to the water of a predetermined volume. Then the water is separated from the sample solvent, and the pH value of the water is measured with a pH meter. The result of the measurement is regarded as the pH value of the organic solvent.
