Abstract: PURPOSE:To eliminate graininess to make a titled screen bright, and to execute easily focusing by converting a reticle pattern to a large area by a step and repeat method, forming a mask, and recording this mask pattern as a smooth uneven part on a photosensitive material. CONSTITUTION:A reticle pattern constituted by scattering a figure semiregularly is repeated by a step and repeat method and obtains a large area to produce a mask and subsequently, the pattern of this mask is recorded as a smooth uneven part on a photosensitive material.

Filed: 1991-04-15
Abstract: PURPOSE:To prevent write data from being written in an address different from an address to originally write the data. CONSTITUTION:Only when an address switching circuit 3 selects a write address bus 2 among a read address bus 1 and the write address bus 2, a gate circuit 11 is conducted and a reference timing signal on a reference timing signal line 9 is applied to a write pulse generating circuit 7. The write pulse generating circuit 7 generates a write pulse synchronously to the reference timing signal and applies the pulse through a write pulse signal line 8 to a RAM 5. Synchronously with the write pulse, the RAM 5 writes the write data on a data bus 6 to the address designated by an address input. Since the write pulse is applied to the RAM 5 after the write address bus 2 is selected by the address switching circuit 3, the write data are prevented from being written in any address excepting for the write address.

Abstract: PURPOSE:To disuse the pattern matching work of a steel plate by arranging a guide gear wheel at the end part of the upper and lower embossing rolls of a steel plate embossing machine and by making the guide gear wheel engaged as it is even in case of the non-engagement of a matching gear wheel. CONSTITUTION:The engagement of matching gear wheels 16, 16' are dissolved by descending the lower emboss roll 15 by actuating a pressure cylinder 19 in case of passing the connection part of a steel plate between the upper and lower rolls 14, 15. Guide gear wheels 21, 21', however, hold the engagement, passing the connection part between both rolls 14, 15 with both rolls 14, 15 in the same rotating state. Thereafter, the lower emboss roll 15 is ascended so as to become the original roll shaft core gap by actuating the pressure cylin der 19. In this way the re-matching of the pattern of the steel plate becomes disused due to no relative movement being caused between both rolls 14, 15.

IPC: G06F7/487
Filed: 1989-03-31
Abstract: PURPOSE:To especially decrease the bit width of a subtracter to subtract the constant of the bit width by providing a means, which compensates a low-order insufficient part so that either one of the exponential part, whose width is less than the maximum value, of a multiplier and the exponential part of a multiplicand may be surely inverted with respect to the other part, and then adds one. CONSTITUTION:When the bit width of an adder 1 is set at (n) bits, inputs X and Y are set at (n)-(m) bits (m)<(n). For Xm and Ym corresponding to the insufficient (m) bits for the bit layer of the adder 1, zero or one is compensated so that the corresponding bits may be mutually inverted. In the adder 1, the (n)-bit operation is executed, and an expression (X+Y)X2<m>+SIGMA2<k> ((k)=0 to (m)-(n)-1) is obtained. One is added to the lowest-order, and an expression (X+Y)X2<m>+2<m>, in which the compensated part becomes zero, is obtained, and by ignoring the (m) bits in the lowest-order, an expression X+Y+1=(x)+(y)+B +2<n-1> can be obtained. Thus the bit width of the subtracter to subtract the constant of the bit width of the adder can be especially decreased.
