Title: Square arithmetic operation system in computer
Inventor: TANNO KOICHI
IPC: G06F7/552
Filed: 1988-06-27
Abstract: PURPOSE:To reduce a circuit size required for arithmetic operation and to improve the efficiency of square arithmetic operation by finding the squared value of a number to be operated by adding a square arithmetic term and mutual arithmetic term to each other and making the square arithmetic operation with a multiplier having smaller number of digit than that of the number to be operated. CONSTITUTION:A number X to be operated is coded into a binary (n) digits of Xn, Xn-1...X2, X1 and by dividing X into lower-order (m) digits and high-order (n-m) digits so that a divided number A0 of low-order (m) digits and number A1 of high-order (n-m) digits can be obtained. Then the squared value of the number X is expanded into the square arithmetic term (a terms including A0<2> and A1<2>) and mutual arithmetic term (a term including A0<2>.A1). Then the arithmetic operation of the square arithmetic term is performed in such a way that the A0<2> and A1<2> are respectively calculated by using multipliers corresponding to the (m) and (n-m) digits and A1<2>.2<2m> are found by shifting A1<2> leftward by 2m bits. The found A1<2>.2<2m> are added to the A0<2> value. The arithmetic operation of the mutual arithmetic term is carried out in such a way that the A0.A1 are calculated by using a multiplier corresponding to the (n-m) digits and the calculated result is shifted leftward by (m+1) bits.

Title: Magnet roll developing device
Inventor: NISHIKAWA MASAHARU
IPC: G03G15/09
Filed: 1979-12-08
Abstract: PURPOSE: To eliminate the uneven development and thus obtain a fine-density image, by dividing the magnetic pole forming the development main pole of the magnet roll into several parts with an interval part secured and at the same time providing the magnetic substance at the internal part.  
     CONSTITUTION: For the development main pole, the magnets 5A and 5B are disposed so that the same pole may oppose to the face 1 to be developed with an interval secured, and at the same time the magnetic substance 12 such as the iron plate or the like is installed between the magnets 5A and 5B. Thus a magnet roll development device is constituted. In such constitution, a high density of the line of magnetic force is secured at the part identical to the center part of the development main pole extremely close to the magnet face and where the line of magnetic force passes through as well as the part which is more outer than the center part and where the line of magnetic force is generated toward almost the upper side. And the density of the line of magnetic force becomes extremely low at the center part which is apart slightly from the magnet face. Therefore, the upstanding tufts 2A and 2A' are formed at the two independent areas of the development main pole part. Thus the uneven development can be eliminated to obtain a fine-density image.

Filed: 1983-08-30
Abstract: PURPOSE:To enable the realization of complete flattening by simple processes by a method wherein a completely flattened insulation film is buried in a field region where parts of different widths are mixed. CONSTITUTION:Masking materials 22 are selectively formed on an Si substrate 21, and then grooves 23 of different widths are formed in the field region. Next, an SiO2 film 24 having a thickness equal to or more than the depth of the groove 23 is deposited over the entire surface of the substrate 21. Then, a low- viscosity polystyrene series resist film 25 is applied over the entire surface as a polymer film which shows fluidity by heating and hardens by irradiation with radiations or electron rays. The film 25 is flattened by heat treatment, and is then hardened by irradiation with far ultraviolet rays over the entire surface. The state that the film 24 on the element-forming region exposes and the film 25 remains around it is obtained by entire surface etching. With the film 25 as a mask, the film 24 is selectively etched, resulting in the exposure of the surface of the substrate in the element-forming region. Finally, the film 25 is removed, and accordingly the state of the flat burial of the film 24 is obtained. Thereafter, the process of element formation is followed.
