Title: Brushless motor control
Inventor: MORI TOMOYUKI
IPC: H02P6/06
Filed: 1996-03-12
Abstract: PROBLEM TO BE SOLVED: To continue position detection operation by preventing stopping and out-of-step without any interference with rotation control even in case of being unable to detect position of a rotor in a brushless motor. SOLUTION: In carrying out rotation control of a brushless motor 4, the voltage of an armature winding in the motor is compared with reference voltage by a position detection part 10 for attainment of a position detection signal D. The detection signal D is inputted into a control circuit 11 to detect the position of a rotor 4a in the motor, and based on the position detection, current- carrying of the winding voltage of the motor is switched. At this point, the control circuit 11 counts time between position detection intervals. Based on the counted time, the time corresponding to a phase angle 30 is predicted from the position detection and position detection at the predicted time is checked. In case of no position, present current-carrying switching is conducted based on a previous switching time of current-carrying.  In case of no position, the control circuit 11 adds the content of position detection register by one. For presence of position detection, the circuit subtracts the content of the register by one. If the content of the register is the prescribed value or more, applied voltage of the motor is decreased to the prescribed value.

Title: Reading circuit
Inventor: SUZUKI EIJI
IPC: G11C7/00
Filed: 1985-04-18
Abstract: PURPOSE:To attain the correspondence between the addresses and data by using a high-speed data read/write circuit to write the low-speed data given from a low-speed data read circuit to the same address of a high-speed memory circuit and to read out the written high-speed data when no write pulse is available. CONSTITUTION:The low-speed data D1-D11 are written to a low-speed memory circuit 2 and a high-speed clock is divided into two frequencies and applied to an address counter 1. Then the data D1-D11 of a ROM2 corresponding to the low-speed addresses A1-A11 sent from the counter 1 are read out and also applied to an address coincidence circuit 8. While the high-speed addresses A1-A10 corresponding to high-speed clocks are partly applied also to the circuit 8. A high level is delivered from an EX-NOR circuit 8-1 when the coincidence is obtained between addresses of both sides. This high-level output and the reverse output of the high-speed clock are applied to a NAND circuit 8-2 together with the output of a low level applied to a high-speed memory circuit RAM9. Then the low-speed data having the coincidence of addresses at its fall point is written to the same address of the RAM9. Thus the correspondence is secured between addresses and data.

Abstract: PURPOSE:To make a DC component of less than the effective accuracy of measured data eliminable as well by removing a zero frequency spectrum or an offset equivalent value from frequency spectra after the Fourier transformation of nuclear magnetic resonance signal data. CONSTITUTION:A sum total of data is found out of several points at both vertical ends in zero frequency by a process 140 at real part data after fast Fourier transform in the frequency encode direction. Next, the means value is found by dividing a number of data added to the total, setting this value down to a DC offset component by a process 141. In addition, a DC offset value found out of all zero frequency data in a phase encode direction is subtracted and stored in the original spot by a process 142. Moreover in regard with imaginary part data after the frequency encode Fourier transform, it is carried out from the process 140 to the process 142 likewise. Thus, such data with no DC offset component are securable. Afterward, the fast Fourier transform in the phase encode direction takes place.
