Filed: 1996-12-13
Abstract: PROBLEM TO BE SOLVED: To suppress a reference leak and a noise by holding a loop band constant by comparing the phase of a frequency frequency with the phase of oscillation of a voltage-controlled oscillator, varying the phase comparison frequency, and controlling a cutoff frequency corresponding to it. SOLUTION: With frequency setting data DF, a control circuit 8 sets the numbers of frequency divisions of 1st and 2nd variable frequency dividers 2 and 4. Consequently, a phase comparator 5 sets the phase comparison frequency and loop band between the oscillation frequency of a reference frequency oscillator 1 and the oscillation frequency of the voltage-controlled oscilltor 3. Further, they are inputted to a rejection filter 7 through an active filter 6. A digital value corresponding to the frequency setting data DF which is inputted at the same time is outputted from a ROM 9 and converted by a D/A converter 10 into a voltage, which is applied to a varactor VD of the rejection filter 7. Consequently, the capacity of the varactor VD varies and the cutoff frequency is varied together with the input of the phase comparison frequency from the phase comparator 5.

Title: A.c. motor controller
Inventor: OHASHI TAKANORI
IPC: H02P23/18
Filed: 1995-12-21
Abstract: PROBLEM TO BE SOLVED: To provide a system which has current control with excellent stability in regenerating, in an A.C. motor controller which always requires a compact size and highly efficient drive. SOLUTION: A vector phase θc is calculated, by a voltage/current phase difference calculating circuit 19, from both the voltage command value and primary current of an A.C. motor. This is inputted into the second voltage command circuit 20 and second voltage command value of d-axis and q-axis is calculated, using the vector phase θc and current deviation of d-axis and q-axis. By correcting the voltage command value on the basis of this value, the stability of a current control system is improved. As a result, stable current control can be obtained even in regenerating and field weakening control in the control of the A.C. motor. It is thus possible to provide a compact A.C. motor which can always conduct highly efficient driving.  This A.C. motor controller is effective, especially for a crane (hoist) which uses power running/ regeneration, and for an electric car which must drive downhill for a long time.

Title: Integrated circuit test method and integrated circuit test apparatus
Inventor: YOSHINO KENJI
IPC: H01L21/66
Filed: 1992-12-15
Abstract: PURPOSE:To efficiently judge whether a defective unit has become defective created in the production of integrated circuits. CONSTITUTION:A defective created in the production of an integrated circuit is judged by determining whether a MOS integrated circuit 30 as a test target is a defective unit through which a leakage current flows to the internal PN junction to which a reverse voltage is being applied. A power supply voltage VDD lower than the voltage at which a current in forward direction of the PN junction can flow is applied to the MOS integrated circuit 30 by a test power supply circuit 14. The power supply current IDD at that time is greatly depending upon the presence of absence of a leakage current. Thus, whether a defective or not is judged from the size of the relevant power supply current IDD.
