Title: Production of ultrahigh molecular weight polyethylene lining roll
Inventor: ENAMI HIROHIDE
IPC: B29L31/32
Filed: 1987-08-24
Abstract: PURPOSE:To produce rapidly and with small heat loss a roll having an outer surface of excellent durability, by cutting a ultrahigh mol.wt. polyethylene resin formed in a cylindrical body by means of ram extrusion while it is kept at the crystallizing temp. or higher, inserting said cylindrical body into a roll base body and shrinking it by cooling. CONSTITUTION:A cylindrical body 13 of ultrahigh mol.wt. polyethylene is molded by means of a ram extruder and is cut while it is kept at the crystallizing temp. or higher or ultrahigh MW polyethylene resin. After the cylindrical body 13 is inserted into a roll base body 15, it is cooled and shrunk. A required time for lining molding is thereby shortened and heat energy for reheating can be saved. Moreover, it is not necessary to carry out such treatment as improving flatness of the outer surface of the roll base body and the finished dimensional accuracy. Furthermore, it is possible to produce an ultrahigh mol.wt. polyethylene lining roll having excellent impact resistance, abrasion resistance, chemical resistance and durability and wherein a lining material tightly adheres on the roll base body.

Title: Method of supplying gas and device therefor
Inventor: KOMAI KEN
IPC: F17C13/02
Filed: 1988-08-24
Abstract: PURPOSE:To make it possible to adjust the gasifying amount of liquefied gas from a heat-insulated container by producing a pressure differential between the gasifying pressure of the liquefied gas in the container and the gasifying pressure of liquefied gas in a container disposed upside down in the heat- insulated container. CONSTITUTION:By producing a pressure differential between the gasifying pressure of liquefied gas in a heat-insulated container 1 and the gasifying pressure of liquefied gas L in a cylindrical container 4 disposed upside down in the heat-insulated container 1, the gasifying amount of the liquefied gas L from the cylindrical container 4 is adjusted. When liquefied gas which has be gasified through a gasifying passage 6 is consumed, the gasifying pressure of liquefied gas L in the cylindrical container 4 becomes lower than the gasifying pressure of liquefied gas in the heat-insulated container 1. The liquefied gas in the heat- insulated container 4 enters into the cylindrical container 4 from the lower side of the latter due to pressure equilibrium, and then makes contact with a heat-transmission medium 5 in the cylindrical container 4 so as to promote gasification.

Abstract: PURPOSE:To ensure the effective use of a memory and to accelerate the processing speed by allotting previously an all-zero cell to a virtual space where the image data is transferred and then allotting dynamically a real memory when the non-zero data of check unit is transferred. CONSTITUTION:When the image data on a data bus 12 is in an all-zero state, a control circuit 10 cuts the data to a real memory 6.
