摘要： A method for preparing a multi-cellular foamed board of thermoplastic resin which comprises forming under pressure in a die a thermoplastic resin melt containing a foaming agent to give the resin melt a shape of a flat board having a broad width compared with a thickness thereof, extruding the resin melt from the die having the convex forward end with a middle portion in the width direction thereof protruding the greatest toward the extruding direction, introducing thus extruded resin melt immediately into a moulding passage having a concave end engaging with the said convex forward end of the die, allowing the resin melt to expand in the thickness direction at the portion adjacent to and extending along the concave end of the passage, and thereafter allowing the resin melt to expand in both the thickness and width directions of the board in the passage.

摘要： A multi-bus semiconductor device and a method of its probing test perform the DC test for individual pads of a device while dealing with an adequate number of devices for simultaneous measurement based on the scheme of input/output pad number compressive test. The semiconductor device includes switch elements SW0-SW4 connected between input/output pads P0-P4 and a testing line L0 so that pads in an arbitrary combination, among the off-probe pads P1-P4 that are not made in contact with the tester probe Pr0, are selected for testing in correspondence to the combination of switch elements that are turned on. The input/output buffers of the pads under test are deactivated to block their internal current paths. The corresponding switch elements are turned on to connect the off-probe pads under test to the probe pad P0 that is made in contact with the tester probe Pr0, and the leak current of the probes is measured with the tester TS.

摘要： An improved process and apparatus for producing a thermoplastic resin foam by mixing a thermoplastic resin, a blowing agent and other necessary components in a molten state and extruding the mixture to expand. The apparatus comprises a metering zone provided at the front end of the rotating shaft in an extruder, a kneading zone provided closer to the rear end than the metering zone, and a plurality of perforated plates mounted on the surface of the shaft in the kneading zone. The outside diameter of said shaft is made smaller than that of the screw in the metering zone as measured at the bottom of channels. This feature combines with the perforated plates to insure uniform mixing and consistent extruding operations.

摘要： A process for producing a polystyrene resin foam is disclosed, which comprises supplying an extruding machine with a polystyrene resin, a fine inorganic powder and a highly volatile foaming agent, heating them to melt, and extruding the melt from the nozzle into a zone of the lower pressure, wherein 0.01 to 2 parts by weight of an alcoholic ester of a higher fatty acid is added to 100 parts by weight of the polystyrene resin. The process insures that foams having a skin of good aesthetic appeal that are free from staining and malodor can be produced consistently for a prolonged time without any fire hazard.
