Title: Multiplication remainder operation method and arithmetic unit
Inventor: YAMAZAKI HIROSHI
IPC: G06F7/52
Filed: 2002-04-19
Abstract: <P>PROBLEM TO BE SOLVED: To provide a multiplication remainder operation method and an arithmetic unit that shorten operation time by reducing the number of times of multiplication and addition, eliminate restriction in an input value, enable remainder operation exceeding the maximum bit length where the operation of multipliers/adders to be used can be made, and do not depend on a Montgomery method.  <P>SOLUTION: In the case of N=2<SP>n</SP>-M and X=α×2<SP>n</SP>+β, the fact that XmodN is equal to (α×M+β)modN is utilized. The solution of n<SP>2+1</SP>modN is set to be b, A×B is set to be X, and the XmodN is converted to (X/2<SP>n+1</SP>×b+Xmod2<SP>n+1</SP>)modN for further converting to (Xn/2<SP>n+1</SP>×b+Xnmod2<SP>n+1</SP>)modN. Until the bit length of the Xn becomes n+1, the operation of Xn/2<SP>n+1</SP>×b+Xnmod2<SP>n+1</SP>is repeated, and Xn-N is obtained, which is set to be the solution of 'A×BmodN'.  <P>COPYRIGHT: (C)2004,JPO

Title: Motor control system
Inventor: YONEDA ISAMI
IPC: H02P7/06
Filed: 2002-04-23
Abstract: <P>PROBLEM TO BE SOLVED: To reduce the size of a motor control system by supplying a current and a control signal for driving a motor through a common distribution system thereby eliminating a harness or a connector.  <P>SOLUTION: A DC current becoming the drive power of a motor 2 and a control signal generated by a controller 1 are inputted to a mixer 3 of the controller 1 and superposed. The DC current and the superposed high frequency control signal are carried from the mixer 3 to a wave separator 4 of the motor 2 through a power line carrying communication cable 8. The wave separator 4 separates a DC current and the control signal, and the DC current becomes the drive power of the motor 2 whereas the control signal is inputted to a control section 9 in order to perform various controls of the motor 2. Since power line carrying communication superposing the control signal on the DC current is employed, the controller 1 side and the motor 2 side simply require a set of power line carrying communication connectors 7a and 7b and a set of power line carrying communication cables 8, respectively.  <P>COPYRIGHT: (C)2004,JPO
