    Abstract: A hard roll is produced by a process utilizing the steps of winding a fiber material impregnated with a thermosetting resin around the outer peripheral surface of a metal roll core to form a fiber-reinforced lower winding layer, then injecting a thermosetting synthetic resin material into a mold of predetermined size and curing the material at a specified temperature to form an outer layer hollow cylinder separately from the first step. The next stepsave fitting the outer layer cylinder around the roll core covered with the winding layer, and injecting an adhesive of low viscosity into an annular clearance between the winding layer and the cylinder and then curing the adhesive at a specified temperature to bond the winding layer to the cylinder with the layer of adhesive.

It is still another object to provide a process for fabrication of the above device.The dielectrically isolated semiconductor device of the present invention comprises a substrate supporting single-crystalline silicon via an oxide film (SOI substrate), the substrate supporting an active element layer deeper than an expanded distance of a depletion layer subjected to the highest voltage applied to the device, and element isolating region which encloses the active element layer. The element isolating region contains a deep trench which comes into contact with the insulation layer on the SOI substrate, and is filled with n heavily doped layers on both side walls, second insulation films each adjacent to the n heavily doped layer and polycrystalline semiconductor layer formed between the second insulation films.

In a lateral type SIT (Static Induction Transistor) in which a first region is used as a p+ gate and a gate electrode is formed on the bottom of the first region, the structure is built such that the p+ gate and an n+ source are contiguous. An insulating film is formed on the surface of an n− channel, and an auxiliary gate electrode is formed on the insulating film. In addition, the auxiliary gate electrode and the source electrode are shorted.
