Title: Division circuit for finite field
Inventor: HATTORI MASAYUKI
IPC: G06F11/10
Filed: 1989-12-11
Abstract: PURPOSE:To make a circuit scale compact and to accelerate calculation speed by calculating the inverse element of a divisor out of a divident and the divisor expressed by a vector with (m) bits on a finite field GF (2<m>) by vector expression and multiplying the divident and the inverse element of the divisor while converting one of them to a matrix expression. CONSTITUTION:When a quotient x/y of two elements (x) and (y) on the finite field GF (2<m>) is calculated, at first, an inverse element y<-1> of the first element (y) is generated with the vector expression by an inverse element generating circuit 3 and afterwards, multiplier circuits 1 and 2 convert the second element (x) to the matrix expression and multiply this element (x) in the matrix expression and the inverse element y<-1> in the vector expression. Then, the quotient x/y is calculated in the vector expression. In comparison with a conventional circuit using a ROM as three conversion tables, the circuit scale of the inverse element generating circuit 3 becomes about 1/3 and the inverse element generating circuit 3 is used only once. Thus, the circuit scale of the multiplier circuit on the finite field GF (2<m>) is made compact and the calculation speed can be accelerated.

Title: Control device of induction motor
Inventor: YURA MOTOSUMI
IPC: H02P21/22
Filed: 1998-11-11
Abstract: PROBLEM TO BE SOLVED: To prevent the identification accuracy of secondary resistance from degrading by correcting primary resistance and leakage inductance based on an excitation current error, a torque current command, or a torque current detection value, and the like. SOLUTION: An adder 5 calculates an angular frequency command ωbased on a slide angular frequency ωs and a rotary angular frequency ωm of an actual induction motor 28. Also, a subtractor 11 subtracts an excitation current detection value ild from an excitation current command ild* and calculates an excitation current error. Then, correction is made so that the value of a converter 20A becomes equal to that of primary resistance rl of the induction motor 28 based on the excitation current error, the torque current command ilq*, or a torque current detection value ilq. Further, the angular frequency command ω is also added, thus performing correction so that the value of a converter 13A becomes equall to that of leakage inductance Lσ of the induction motor 28, thus eliminating the identification error of the secondary resistance and constantly achieving a desired output torque with improved accuracy.

IPC: F23D14/22
Filed: 1991-10-01
Abstract: PURPOSE:To stabilize flames, adopt low calorie gas and replace a partitioning board in a burner cylinder with ease by forming a pilot combustion chamber in which a pilot burner is opened between a front partitioning board and a rear partitioning board. CONSTITUTION:A front partitioning board mount flange 8 is fixed slightly in the front side while a rear partitioning board 9 is fixed slightly in the rear side on the outer periphery of a main burner 7. The front partitioning board mount flange 8 is mounted to a front partitioning board 10 with a bolt 14. A chamber formed between the front partitioning board 10 and the rear partitioning board 9 is used as a pilot combustion chamber A where a pilot gas burner 12 is opened. More specifically, a gun burner 6 is ignited by a spark plug 11 in a pilot gas burner in a pilot combustion chamber A. Therefore, since the gun burner 6 eliminates the need for ignition, there is installed no intermediate partitioning board, which is simple in structure. One piece structure makes it possible to stabilize the flames and operate the gun burner even when a low calorie gas is used.
