Title: Inference method
Inventor: AKIFUJI SHIYUNSUKE
IPC: G06F9/44
Filed: 1989-03-31
Abstract: PURPOSE:To improve inference efficiency by accumulating knowledge used in the inference of a certain problem into a knowledge base after converting to more concrete knowledge. CONSTITUTION:A secondary knowledge base 2 stores secondary knowledge converted so that primary knowledge can be applied to concrete phenomena. An inference engine 4 performs the inference referring to a work storage part 5 and the secondary knowledge base 2, and generates the secondary knowledge from the primary knowledge stored in a primary knowledge base 1 and stores it into the secondary knowledge base 2 when no secondary knowledge exists, then, restarts the inference. Thus, since the secondary knowledge is accumulated in the secondary knowledge base adaptive for a work storage element after inferring a certain problem once, it is not required to perform the inference using the primary knowledge if knowledge applicable on the secondary knowledge base exists when a new problem is inferred, which improves the inference efficiency.

Title: Controlling of power inverter
Inventor: TANAKA SHIGERU
IPC: H02M7/48
Filed: 1989-03-31
Abstract: PURPOSE:To compensate DC magnetization of an output transformer and to control a load current accurately by controlling an exciting current of the output transformer and a current supplied to a load. CONSTITUTION:A power inverter is constituted of the first PWM inverter INV-1, the second PWM inverter INV-2, AC load LOAD and controlling circuit. The second PWM inverter INV-2 controls the current supplied to the load irrespective of output frequency. The first PWM inverter INV-1 controls so that an exciting current of an output transformer TR becomes approximately constant. In case DC magnetization occurs in the output transformer TR, the exciting current of the output transformer TR normally increases, however, the exciting current is so controlled that it corresponds with the command value. According to the constitution, even if DC magnetization occurs in the output transformer TR, the break-down of an element by an overcurrent can be prevented.

Title: Radar apparatus
Inventor: ASANO KOICHI
IPC: G01S13/34
Filed: 1998-03-26
Abstract: PROBLEM TO BE SOLVED: To obtain a radar apparatus which enhances detecting reliability of the distance, speed and direction of a target. SOLUTION: A transmitting antenna 14 transmits frequency modulated waves. Reflected waves from a target are received by right and left two channel receiving antennas 16a, 16b. A signal processor 20 finds the direction of the target by a phase monopulse system on the basis of the difference between a right received signal and a left received signal. The direction is detected at a rise phase and a fall phase in an FMCW system. In addition, the signal processor 20 finds the distance and the speed of the target by the FMCW system. The distance and the speed are detected individually on the basis of the received signals in the right channel and the left channel. Consequently, one set of detection data are obtained for the direction, distance and speed.  On the basis of a difference in the direction, a difference in the distance and a difference in the speed, a detected result is judged to be effective when the differences are small.
