Title: Engraving apparatus and method
IPC: B44B3/06
Filed: 1980-06-10
Abstract: The invention relates to a method and apparatus for engraving the surface of a gravure printing cylinder with a pattern adapted to be repetitively printed with a joint (J) between the adjacent printed patterns being less visible to the human eye. The method includes scanning a copy (C) of a pattern having selected opposite ends adapted to form a joint on the gravure printing cylinder, and electronically sensing the copy density at two locations (L1, L2), on the pattern copy (C) adjacent the opposite ends. The densities at the different locations are electronically compared, and a correction factor based upon the comparison is electronically determined. Generally circumferentially extending rows of peripherally cells are engraved within the cylinder surface according to the pattern, and the depth of the engraved cells corresponding to the opposite ends of the copy is adjusted according to the correction factor to correct for unbalance in copy density at the two locations (L1, L2) on the pattern copy (C).

Patent EP-0215532-A3 (EP)
IPC: G03F1/00
Filed: 1986-09-17
Abstract: The mask part 41 includes a substrate 1, a patterning means 40 
and a photoemissive layer 6. The patterning means 40 includes a 
mask pattern 2, 3 of apertures 3 and masking areas 2 and a 
modifying layer 4. Ultraviolet radiation 56 is patterned by 
patterning means 40 before effecting electron emission 60 from the 
photoemissive layer 6. There is electron emission from over the 
apertures 3 and the masking areas 2 as the masking areas are 
partially transparent to incident ultraviolet radiation. The 
ultraviolet transmitted by the apertures and the masking areas is 
modified in intensity dependent on the thickness R of the modifying 
layer. The resuting electron emission 60 is in a patterned beam 
which forms a proximity effect corrected electron image of the mask 
pattern in the electron sensitive resist layer 63. The masking 
areas 2 of chromium and the modifying layer 4 of resist may be made 
by modifications of known methods of chromium deposition and resist 
exposure and development. The use of the mask in the manufacture 
of a solid state device allows a single exposure of a resist layer 
63 to form a proximity effect corrected image of the mask pattern 
2, 3 in the resist layer 63.

Title: Multi-bus microcomputer system with bus arbitration
IPC: G06F9/44
Filed: 1989-03-03
Abstract: A multi-bus microcomputer system includes a cache subsystem and an arbitration supervisor. A CPU is provided with a PREEMPT signal source which generates a preempt signal in CPU cycles extending beyond a specified duration. The preempt signal is effective at any device having access to the bus to initiate an orderly termination of the bus usage. When that device signals its termination of bus usage, the arbitration supervisor changes the state of an ARB/GRANT conductor, which had been in the grant phase, to the arbitration phase. During the arbitration phase each of the devices (other than the CPU) cooperates in an arbitration mechanism for bus usage during the next grant phase. On the other hand, the CPU, having asserted preempt, responds to a signal indicating initiation of the arbitration phase by immediately accessing the system bus.
