Title: Motor controller
Inventor: NAGASHIMA ICHIRO
IPC: H02P6/28
Filed: 1998-12-15
Abstract: PROBLEM TO BE SOLVED: To provide an inexpensive low power consumption motor controller adaptable to high temperature. SOLUTION: In d-axis current correcting process, the value of d-axis correction current id is determined, at first, at step 510 according to formula id=f(T), where (f) is a function for determining the d-axis correction current id from the temperature T. At step 520, a command current Id corrected depending on the temperature T of the d-axis is determined according to formula Id=id*+ id. Since the command current for driving the motor M has a d-axis component not equal to 0, magnetic force (flux) of a permanent magnet which weakens as the temperature rises can be compensated when the temperature is high. The current amplitude Im is determined according to formula Im=(2/3)1/2(iq*2+ id2). When 0<id<=Δiq, the current amplitude Im decreases as compared with a conventional case resulting in a small, inexpensive, low power consumption motor controller.

Title: X-ray tube for very high speed x-ray ct
Inventor: KIMURA YUTARO
IPC: H01J35/24
Filed: 1991-12-27
Abstract: PURPOSE:To eliminate the dislocation of an X-ray focus position, and obtain the excellent CT image by sliding one point on a surface in parallel with the X-ray focus surface on a fixed support part surface at the time of thermal expansion of an anode targe structural body. CONSTITUTION:An X-ray tube has an electron colliding surface 12A and a surface 24B (the back surface of a cooling ring 24 is inclined) in parallel with the surface 12A, and the inclined surface 24B contacts to a roller 20 of a fixing base arranged in a part of a circumference, and tries to slide. When the thermal expansion of an anode target 12 is started by the input electron (e), the anode target 12 tries to be extended in the radial direction, but since the inclined surface 24B is slid by the roller 20, the anode target 12 is moved only in the arrow direction in parallel with the colliding surface 12A along the surface 24B. Consequently, an electron collision point on the target 12 is dislocated, but a position as X-ray generating sources (Rc, Zx) required for CT are not changed, and the deterioration of CT image is not generated.

Abstract: PURPOSE:To prevent production of a pseudo clock by comparing a phase of a comparison clock signal with a phase of an output of a frequency divider, applying a phase error signal and a frequency error signal to a VCO so as to make the oscillated frequency close to a prescribed value. CONSTITUTION:A phase comparator 2 compares a phase of a comparison clock signal REF with a phase of an output SD of a frequency divider 9 to output a phase error signal TU and it is inputted to a signal synthesis circuit SM via a switch circuit LP. On the other hand, a frequency phase circuit 3 uses a master clock MC to count a frequency of the output SD and to output frequency error signals FU, FL and they are inputted to the circuit SM and to a gate signal generating circuit GS. The signals TU, FU and TL, FL are sent to a VCO 8 via the circuit SM and a loop filter 7. In this case, while a phase error signal from the comparator 2 is fed to the filter 7, when the frequency error signal is outputted from the comparator 3, the phase error signal is not fed to the filter 7, the oscillating frequency of the VCO approaches a prescribed value to prevent a pseudo clock.
