Abstract: A method for fabricating an MOS memory array is disclosed, which includes steps for constructing electrically-programmable and electrically-erasable memory cells (2, 198,200) in combination with assorted peripheral devices (202, 204, 206) on a semiconductor substrate (8, 71). Tunnelling regions (20, 78) are formed in the substrate (8,71) and thin tunnel dielectrics (22, 84) comprised of silicon dioxide/oxynitride material are grown over the tunnelling regions (20, 78) to facilitate transport of charge carriers between the tunnelling regions (20, 78) and subsequently- fashioned floating gate structures (14R, 14L, 156) in the memory cells (2, 198, 200). A first layer of doped polycrystalline silicon is deposited over the substrate and etched to define large polysilicon areas. An oxide layer is grown over the large polysilicon areas in a manner such that out-diffusion of the impurity present in the large polysilicon areas is prevented. Thereafter, a second layer of doped polycrystalline silicon is deposited over the substrate and etched together with the large polysilicon areas to define the memory cell floating gate structures (14R, 14L, 156) as well as various memory cell programme and control gates (16R, 16L. 40R, 40L, 128, 132) and peripheral device control gates (136, 138). Source and drain regions (34, 36, 58, 60, 64, 66, 168-179) for the memory cells (2,198,200) and the peripheral devices (202, 204, 206) are established by implanting an impurity in the semiconductor substrate (8, 71), using the memory cell programme and control gates (16R, 16L, 40R, 40L, 128, 132) and the peripheral device control gates (136, 138) for alignment. Protective coverings of refill oxide (188) and VapOx (190) are formed over the substrate to complete the fabrication process.

Abstract: An improved tensioning device is provided for use in an inner diameter saw blade housing (10). A tensioning ring (16), disposed in an annular clamping member (20), is internally threaded at a plurality of locations along its circumference. An associated plurality of screws (50), disposed in cylindrical recesses in the clamping member, threadedly engage the internal threads. The screws (50) may be turned through an opening in the clamping member having a diameter smaller than the screw to thereby precisely tension the blade (38) as desired. Since the screws ate captive within the clamping member (20), migration of the tensioning ring relative to the blade is prevented. Further, the screws do not protrude from the surface of the clamping member and the threaded portion of the screws are closed off from the ambient such that foreign matter cannot enter the clamping member and interfere with the tensioning process.

Abstract: The controlled deflection roll comprises a stationary, non-rotating roll support member and a roll shell mounted to rotate about the stationary roll support member. The roll shell is not directly supported at the stationary roll support member by means of hydraulic support elements, but through the intermediary of additionally provided traveling rings each of which defines a travel path for the related hydraulic support element. The traveling rings have an outer diameter slightly smaller than the inner diameter of the roll shell and they are arranged to be rotatable independently of the roll shell. During operation of the controlled deflection roll the traveling rings, therefore, roll along the inner surface of the roll shell. As a result, the flexibility of the roll shell is improved in circumferential direction as well as transversely to the pressing line of the controlled deflection roller. In this arrangement stiffness of the roll shell in circumferential direction is insured by the traveling rings. Undue deformations of the roll shell are thereby prevented and the force requirements are reduced.

Abstract: The invention relates to a two-position switching valve having hydraulic self-holding properties and comprising a closure piston disposed in a flow path for displacement between an open position and a closure position for controlling a pressure between a maximum value and a minimum value, and operatively coupled to a control piston mounted for displacement in a housing. In known switching valves of this type, a creeping approach of respective switching points is scarcely avoidable under certain operating conditions. In accordance with the invention, a reliable switching function is achieved by forming the housing bore as a continuous stepped bore for slidably guiding therein a stepped piston consisting of a closure piston, a control piston, and a piston portion and by providing alternately openable and closable flow connections therein permitting an annular space between the closure piston and the piston portion to communicate with an annular chamber adjacent the control piston in the closure position of the closure piston, and the annular chamber to be pressure-relieved in the open position of the closure piston. These provisions result in the generation of a servo force for abrupt switch-over operation of the valve.
