Title: Processor for division and square root making use of polynomonal approximation expression of root
Inventor: ESU EMU KUETSUKU
IPC: G06F7/533
Filed: 1992-05-11
Abstract: PURPOSE: To provide an improved device and method for calculating the inverse number and the square root. CONSTITUTION: An initial value approximation formula with high accuracy is calculated by using a quadratic polynomial, and the coefficients are stored in an ROM. Address designation is performed to the ROM by using the most significant bit of an operand to select the coefficient, and a different operand range is given to a different coefficient. Operand bits at the residual lower side are used for calculation and the coefficient value indicates the bit used for address designation. As a result, single precision can be obtained. The result, of the polynomial is used as the first approximation formula of a Newton- Raphson successive solution in double precision. A multiplier can calculate once two values with low precision by a division array mode for quickening the calculation of the polynomial.  The size of the coefficients is adapted so as to calculate a proper result with high precision for each element of Ax<2> +Bx+C. In this case, each value of the coefficients A, B, and C must be stored for 1/x approximation formula and 1/(x)<1/2> approximation formula.

Filed: 1997-06-05
Abstract: PROBLEM TO BE SOLVED: To suppress fluidity of a recording film at the recording time and hence to prevent a thickness change of the film and to enhance reliability of data by adding an element having ferromagnetism into the recording film and also forming a ferromagnetic layer via an intermediate layer on the recording film. SOLUTION: A reflecting film 2, a recording film 3 of Ge2 , Sb2 and Te5 materials, a protective film 4, a reflecting film 5 and a magnetic film 6 of a ferromagnetic Co material are formed in a prescribed thickness and layered on a substrate 1 of a thickness of 0.6 mm respectively to form a discoid recording medium, and the magnetic layer 6 is residually magnetized in the vertical direction by a permanent magnet. Consequently, induced magnetization takes place in the recording layer of coexistence with ferromagnetic substance by a magnetic field of the magnetic layer, and a change of the film in thickness due to fluidity of the recording film in the recording layer by laser light is suppressed by constraint of magnetic Coulomb force.  Therefore, fluctuation of a light quantity due to the thickness change of the film is suppressed to eliminate an error signal to be detected, so that the reliability of data is enhanced, and also rewriting durability is improved. For the ferromagnetic material, a transition elements and rare earth metal elements. etc., such as Fe and Sm as well as Ni and Co can be used.

Title: Production of pc steel bar having high uniform elongation, low yield ratio, and excellent high temperature relaxation characteristic
Inventor: YOKOTA TOMOYUKI
IPC: C22C38/58
Filed: 1997-06-05
Abstract: PROBLEM TO BE SOLVED: To obtain a PC steel bar having a high uniform elongation and low yield ratio, excellent in relaxation characteristic at a high temp., and having tensile strength of a specific value or above by hardening a steel, having a specific composition where large amounts of C and (Si+Al) are added, from a high temp. in a specific range. SOLUTION: A steel, which has a composition containing, by weight, 0.5-0.7% C, 0.2-2.0% Mn, and 2.0-5.0% of (Si+Al) and also containing, if necessary, one or more kinds among 0.01-0.1% Nb, 0.01-0.05% Ti, 0.0003-0.005% B, 0.2-1.0% Ni, 0.2-1.0% Cu, 0.1-1.0% Cr, and 0.05-0.5% Mo, is hardened from 1160-1300 deg.C and then tempered. By this procedure, the desired PC steel bar, having >=1080 N/mm<2> tensile strength, can be obtained. Although C contributes greatly to the reduction of low yield ratio and the improvement of uniform elongation under the condition that the amount of (Si+Al) is large, such a remarkable improvement in ductility cannot be expected when the content of C is below the lower limit, and, when it exceeds the upper limit, ductility is deteriorated.  Although (Si+Al) can controbute greatly toward improving uniform elongation, the effect is reduced when the content of (Si+Al) is below the lower limit, and workability is deteriorated when it exceeds the upper limit.

Title: Multi-gain amplifier
Inventor: KADAKA TAKAYUKI
IPC: H03G3/12
Filed: 1989-06-09
Abstract: PURPOSE:To eliminate spike noise by using an analog switch provided with a base effect compensation circuit correcting the fluctuation of an impedance between input and output terminals for a 1st switch and using an analog switch not provided with the base effect compensation circuit for a 2nd switch. CONSTITUTION:Analog switches 8, 9 may generate spike noise by providing a base effect compensation circuit 39. Since the analog switches are not connected to an operational amplifier 1, the noise is not inputted to the operational amplifier 1. On the other hand, analog switches 6, 7 connecting to a resistor 2 have no base effect compensation circuit, therefore for impedance is changed by an input voltage Vi. Since the input resistance of the operational amplifier 1 is large, a current flowing to the analog switch 6 is very small. Since the potential fluctuation at a connecting point due to the changeover of the analog switches is less, a fast response is obtained.
