Abstract: The invention relates to an anti-cancer agent containing ?-chain protein (?-fragment) of HGF (hepatocyte growth factor) as an active ingredient. The active ingredient of ?-fragment has a specific suppressing effect on invasion and metastasis of cancer cells such as gallbladder cancer, lung cancer and other, which are highly metastatic and result in a high mortality. Therefore, the agent of the invention is used in treatment and prevention of cancer as an anti-cancer agent, and is extremely useful clinically.

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: 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.

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: In a pin tenter, a wet film is conveyed and dried in a state that edges of the wet film are pierced by pins. The plurality of pins are fixed to a pin plate. The pin plate is supported by a pin carrier. The pin carrier is disposed between rails. Movement of the pin carrier is guided by the rails. Nitrogen gas is supplied through a nozzle to the inside of a rail cover in a gas purge area, and thus the inside of the rail cover is pressurized. Atmospheric gas containing solvent gas in the pin tenter is prevented from entering the inside of the rail cover. Accordingly, precipitation of additives and the like on the rails and the pin carrier is eliminated. A suction device sucks nitrogen gas together with foreign substances such as dust from the inside of the pressurized rail cover.
