Abstract: 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.

Abstract: Second memory cells of a second memory block each have an area 2a times (a is a positive integer) that of each first memory cell of a first memory block. Sizing the first and second memory cells in a predetermined ratio can make easily identical the dimensions of the first memory block and the second memory block. Consequently, it is possible to easily align peripheral circuits to lie around the plurality of first and second memory blocks, such as decoders. This also facilitates the wiring of signal lines to be connected to the peripheral circuits. This makes it possible to improve the layout design efficiency for a semiconductor integrated circuit. Thus, a plurality of types of memory blocks can be formed on a semiconductor integrated circuit efficiently. The semiconductor integrated circuit can be prevented from increasing in chip size depending on the layout design, owing to its simplified layout.

Abstract: 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.

Abstract: A timer measures a predetermined time from the reception of an external access signal, and outputs an access request signal after the predetermined time has elapsed. The external access signal causes a memory core to execute a read operation, and the access request signal causes the memory core to operate. The predetermined time is set to be longer than a core operation time for the memory core to perform a single operation. The memory core thus performs no operation when the external access signal varies in a time shorter than the predetermined time. Consequently, it is possible to prevent the memory core from malfunctioning and data retained therein from crashing even when external access signals are supplied at intervals at which the memory core is unable to properly operate.

Abstract: The dope prepared from a mixture solvent and solid contents such as cellulose ester and additives is cast on a drum cooled to ?5° C. to form a gel-like film. The gel-like film is peeled off from the drum. Tension of 60 kg/m is applied to the gel-like film in the widthwise direction thereof and the temperature of the gel-like film is kept 120° C., when the content of the solvent to the solid contents in the gel-like film is in a range of 100 wt. % to 20 wt. %. Further the gel-like film is dried to be a cellulose ester film having 40 ?m thickness. The IR spectrum of the cellulose ester film has a peak in a range of 520 cm?1 to 480 cm?1 which indicates the crystallization of the polymer. The cellulose ester film has tear strength of 12 g, Rth of 42 nm and Re of 1.2 nm. As crystallization of the polymer proceeds, the cellulose ester film has sufficient strength and optical properties.

Abstract: A logic chip and a memory chip to be accessed by the logic chip are mounted in a single package. A pattern generator of the logic chip operates during a first test mode to generate internal test pattern(s) for the memory chip. A pattern selector selects, during the first test mode, the internal test pattern(s) outputted from the pattern generator, selects, during a second test mode, an external test pattern supplied via a test terminal, and outputs the selected test pattern to the memory chip. The memory chip mounted in the package is tested by use of, in accordance with a mode selecting signal, either the internal test pattern(s) (the first test mode) generated within the logic chip or the external test pattern (the second test mode) supplied from the exterior.
