Title: Central processing unit
Inventor: KANEKO HIROAKI
IPC: G06F9/32
Filed: 1989-07-21
Abstract: PURPOSE:To protect the arithmetic result flags at high speed with a small number of instructions by inhibiting the change of the flag with a flag control instruction which is carried out before an arithmetic instruction. CONSTITUTION:A control circuit 107 produces the strobe signals STBO - STB3 to designate the changes of the arithmetic result flags 310 - 313 respectively in accordance with each arithmetic instruction to be executed. However the signals STBO - STB3 are masked by the 2-input AND gates 110 - 113 when they are actually applied to the flags 310 - 313. A flip-flop 102 is reset by a DISF signal which shows that an instruction DISFLG which inhibites the change of the flags 310 - 313 is carried out at the end of execution of the subsequent arithmetic instructions. The change of those flags caused by execution of a 2nd arithmetic instruction ADD AW BW can be inhibited by carrying out the instruction DISFLG right before the instruction ADD AW BW. As a result, the arithmetic result flags are protected at a high speed with a small number of instructions.

Abstract: PURPOSE:To reduce the capacity per unit area of the central Al wiring among Al wirings and to contrive the improvement of the operating speed of a semiconductor device by a method wherein polycrystalline silicon layers, which respectively correspond to the Al wirings formed on a field oxide film, are formed. CONSTITUTION:Al wirings 5a, 5b and 5c are formed on a field oxide film 2 formed on a semiconductor substrate 1 and polycrystalline silicon layers 6 are respectively provided corresponding to the respective wirings through an interlayer film 3a which is an insulating film. When attention is paid to a capacity per unit area, which is generated in the wiring 5b, the capacity is divided roughly into the capacities C2 between the wiring 5b and the wirings 5a and 5c adjacent to the wiring 5b and the capacity C1 between the wiring 5b and the substrate 1, but the capacity C1 is decided by the distance L between the wiring 5b and the substrate 1, in short, the sum of the film thickness ls of the film 2, the film thickness of lp of the film 3a and the thickness ld of the layers 6. That is, the capacity C1 is represented by C1proportional 1/L. Accordingly, when the capacity C1 is compared with that in the case where conventional polycrystalline silicon layers do not exist, the value of the L is increased by the amount of the thickness ld of the layers 6 and the capacitance of the wiring 5b is reduced.

Title: Vertical magnetic recording medium
Inventor: SUGIMOTO MAMORU
IPC: G11B5/66
Filed: 1982-10-28
Abstract: PURPOSE:To provide superhigh density in a vertical magnetic recording medium by adding at least one of Ti, V, Mn and Cu as the third element to a Co-Re composition, thereby magnetically isolating between the crystalline grains of the medium. CONSTITUTION:At least one of Ti, V, Mn and Cu is further added up to approx. 10wt% to a Co-Re composition. When the content of the Ti, V, Mn and Cu exceeds 10wt%, the crystallinity of the film remarkably decreases, and the vertical magnetic anisotropy of the film abruptly drops. The magnetic characteristic and the crystalline orientation of the conventional Co-Re of two-element composition are preferable in a range of 12-30wt%, but the lower limit of the quantity or Re extends due to the addition of the Ti, V, Mn or Cu, thereby exhibiting more preferable characteristics as compared with the case of two- element composition.
