Abstract: PROBLEM TO BE SOLVED: To provide an arithmetic method and an arithmetic circuit capable of reducing an error in accumulating products caused from rounding products in a digital signal processing or the like. SOLUTION: By determing so that when a product is positive, the most significant bit of rounding bits is 1, and when the lower bits of it is 0, the value is rounded up, and, when the product is negative, the most significant bit of the rounding bits is 1, and when the lower bits of it is 0, the value is rounded down, the rounding is performed so that a mean accumulation error between when it is positive and when it is negative is canceled. As a correction term for rounding, when the product is positive, a value in which the most significant bit of rounding bits is 1 and bits lower than it are 0, and, when the product is negative, a value in which the most significant bit of rounding bit is 0 and bits lower than it are 1, is added using the partial product adder 2 of a multiplier and an adder 3.

Title: Rudder for two-shaft two-rudder ship
Inventor: YOSHIMURA YASUO
IPC: B63H25/38
Filed: 1988-12-05
Abstract: PURPOSE:To contrive the improvement of propulsive efficiency by forming a rudder surface, not receiving a propeller back wash, in a right-left asymmetrical section bending a sectional shape of the rudder surface by a degree half the inflow angle so as to face the flow in the vicinity of a rudder and a rudder surface, receiving the back wash, in a symmetrical section. CONSTITUTION:A rudder surface 2, not receiving an acceleration flow of a propeller (b), is provided with a camber by bending a front end 1a of a rudder 1 about alpha/2 in a direction toward a flow (c) from a ship side. Accordingly, the rudder surface 2 is formed in a right-left asymmetrical section. A rudder surface 3, receiving the acceleration flow of the propeller (b), is formed in an symmetrical blade section as in the past. Accordingly, a shape of the rudder surfaces 2, 3 is discontinuously changed, but a rudder trailing edge 1b is not changed. By the constitution thus obtained, a rudder, partly providing an asymmetrical surface, increases a lift for a flow (e) from the ship side further obtaining a smooth flow, consequently a drag is decreased, enabling resistance to be reduced of the rudder 1 improving propulsive efficiency.

Title: Protective relay
Inventor: KURIHARA KAZUO
IPC: H02H3/05
Filed: 1992-10-19
Abstract: PURPOSE:To prevent the inessential operation of an alarm output by a method wherein the disagreement of a normal state is monitored by the logical-sum output of the immediate starting signal and the time-limit operating signal of a main detection (M) element and by the immeediate operating signal of a subdetection (FS) element. CONSTITUTION:For example, when an input amount is 1.5 times of settling value, an input current is converted into a prescribe electric amount via a CT 1-1, an REC 1-2, an LPF 1-3 and an AC 1-4 in an M element, a prescribed operation is judged by a CPC 1-5, and an immediate operating signal 1-6 is output. A time-limit operating signal 1-7 is output after 18 seconds. On the other hand, in an FS element, a prescribed judgment is performed by an REC 1-2, an LD 1-8 and a TDD 1-9, and an operating signal 1-10 is output. Thereby, a logical-sum circuit 1-13 outputs an operating signal. Consequently, a disagreement detection circuit 1-12 is not operated because a condition is not established. Thereby, it is possible to prevent the inessential operation of an alarm output 1-16.

Title: Adaptive control method of cyclic signal
Inventor: GOTO KATSUHIRO
IPC: G05B13/02
Filed: 1997-11-07
Abstract: PROBLEM TO BE SOLVED: To provide an adaptive control method of cyclic signals, in which convergence stability of adaptive control and follow-up ability to changes of the angular frequency of the cyclic signals to be suppressed are compatible. SOLUTION: This adaptive control method of the cyclic signals is provided with an adaptive signal generation algorithm 11 for generating adaptive signals y(n) for offsetting the cyclic signals f(n) at an observation point 24, and an adaptive coefficient vector updating algorithm 12, for adaptively updating the amplitude a(n) and phase ϕ(n) of the adaptive signals y(n). Since the adaptive coefficient vector updating algorithm 12 is semi-normalized by [A (ω)+γ] which is the sum of the measured value A(ω) of the gain of a transfer characteristic 23 and a divergence prevention constant γ, an updating notch width is small and stability is high in the frequency band of a high gain A(γ), whereas the updating notch width becomes large and adaptability is improved in the frequency band for low gain A(γ).  As a result, the convergence stability of the adaptive control and the follow-up ability to frequency fluctuation become compatible.
