Abstract:
The invention relates to a roller of the type that comprises, on one hand, a drive shaft (1), which has a cylindrical envelope surface (6) having a certain outer diameter and a certain length, and, on the other hand, a shorter roller ring (2), which includes an outer ring (4) of a hard material and an inner ring (3) concentric with the same and of a more ductile material, which includes a cylindrical inside having a certain inner diameter and is, on one hand, permanently united to the outer ring (4) in a metallurgical way, and, on the other hand, rotationally rigidly connected with the drive shaft (1) in order to, from the same, transfer torque to the outer ring (4). According to the invention, the rotationally rigid joint between the drive shaft (1) and the roller ring (2) solely consists of a shrink-fit joint that is established between the envelope surface of the drive shaft and the inside of the inner ring and has an interference of at least 0,01 % of the outer diameter of the drive shaft (1).

This invention relates to a high density architecture for an integrated circuit package (10) in which a plurality of circuit communication wafers (12) are disposed in a stack with a plurality of cooling plates (14) between them, and wherein circuit communication between the communication wafers (12) is provided from wafer to wafer through the cooling plates (14). In addition, the communication wafers (12) may have integrated circuit chips (18) deposited on both sides of the wafer, and chip-to-chip communication may be provided from one surface of the wafer to another through the wafer. The resulting integrated circuit package may have any desired geometrical shape and will permit heat exchange, power and data exchange to occur in three generally mutually orthogonal directions through the package.
Abstract:
The invention relates to a method for manufacturing a roll coating onto a roll frame (1), which coating comprises a base layer (2) on the roll frame (1) and a surface layer (3) on the base layer (2). The base layer (2) is brought to its final form after the surface layer (3) has been formed and cured or solidified. The surface layer (3) is formed on the base layer (2) and cured or solidified after the base layer (2) has been formed on the roll frame (1).

Abstract:
A method of manufacturing a hard roll for use in an elastic roll of a calendar roll for paper making and the like, according to the invention comprises the steps of pouring a liquid thermosetting resin material into a space between a metallic roll core and an outer die, heating from the outside a greater part of the resin material to harden the same for forming an intermediate having an outer layer of resin while cooling the roll core to leave a viscous liquid stock layer inside the intermediate. Then the intermediate is cooled from the outside of the outer die for shrinkage, and a surplus portion of the liquid stock is pushed upward as the intermediate shrinks. Then the remaining viscous liquid stock is hardened by heating the roll core. According to the method of the invention, the thermosetting resin is prevented from being cracked due to reactive shrinkage and thermal shrinkage of thermosetting resin during the manufacturing of the hard roll. Accordingly, it is possible to efficiently produce a hard roll with exceedingly fewer production steps and reduce production cost thereof, which hard roller is free from cracks on its surface during use and any change in its roll surface hardness and is excellent in durability.

Abstract:
Printing plates are mounted onto a cylinder by first establishing a temperature difference between the plate and the cylinder; in particular, the temperature of the plate exceeds the temperature of the cylinder. The plate is then wrapped around the plate cylinder, and the temperature difference causes the plate to shrink against the cylinder.
