Title: Switching power supply
Inventor: SASAKI MASATO
IPC: H02M7/12
Filed: 1998-10-22
Abstract: PROBLEM TO BE SOLVED: To provide a switching power supply which always has high efficiency regardless of a switching method. SOLUTION: A conducting angle control circuit 2 for controlling a conducting angle of a switching element 3 passes part of the commercial AC voltage 1 through the switching element 3. Then, the output of the switching element 3 is rectified by a rectifier circuit 4 and the output of the rectifier circuit 4 is smoothed by a smoothing capacitor 5. The DC voltage provided by the smoothing capacitor 5 is switched at a high frequency by means of a switching circuit 6, is converted to the voltage of a specified value by a transformer 7, and is rectified and smoothed by a secondary-side rectifying and smoothing circuit 11. The voltage rectified and smoothed by the rectifying and smoothing circuit 11 is supplied to a load 12.  Since the commercial AC voltage 1 is partially passed through the switching element 3, the DC voltage applied to the switching element 6 is low and therefore a power loss is reduced in the switching circuit 6.

Further, a frequency shifter 6c controls the fundamental frequency according to the information on this table 6b. The high frequency is kept away from the received frequency by shifting somewhat the fundamental frequencies of the PWM signal according to the monitored and received frequency.

Filed: 1988-11-30
Abstract: PURPOSE:To take out only a more important noun as the index word by taking out nouns accompanied with case particles from analysis results of morphemes and eliminating unnecessary words from taken-out nouns. CONSTITUTION:A morpheme analysis dictionary file 2 is used to divide a sentence 1 into words by a morpheme analyzing part 3, and information of parts of speech are given to respective words to generate word data 4. A case particle taking-out rule file 5 is used to extract nouns accompanied with case particles by a noun extracting part 6, and noun data 7 is generated. Since nouns accompanied with case particles are extracted, nouns having important meanings in the sentence are taken out. An unnecessary word dictionary file 8 is used to eliminate unnecessary words such as pronouns from noun data 7 in an unnecessary word eliminating part 9, and an index word 10 is extracted. Thus, a more important noun is taken out as the index word when the number of index words given to the object sentence is limited.
