IPC: H01M50/417
Filed: 1986-01-22
Abstract: PURPOSE:To increase storage life and discharge performance by using a synthetic fiber nonwoven fabric containing silicon dioxide powder or silicate powder as a separator placed between a negative electrode and a positive mix. CONSTITUTION:A separator 3 is used by placing between a lithium negative electrode 2 and a positive mix 4.

Filed: 1994-02-04
Abstract: PURPOSE:To prevent underflow and to reduce a delay time by absorbing a delay fluctuation with a buffer and resetting a cell decomposing device when number of cells stored in the buffer exceeds a prescribed number. CONSTITUTION:Every time a cell decomposing device 10 finishes decoding of one cell, the device 10 outputs an underflow signal to urge transfer of a cell to a delay absorption buffer 3. When number of cells stored in the buffer 3 exceeds a reference number, a cell number detector 20 outputs a reset signal to the cell decomposing device 10 to abort a cell during processing and gives an underflow signal to the buffer 3 to allow the buffer 3 to transfer a succeeding cell.

Abstract: PURPOSE:To constantly attain a natural interpretation by providing a step for analyzing the morphological element of an input sentence, a step for analyzing a syntax, a step for extracting a collating destination and a step for ranking based on limit information described in a concept dictionary. CONSTITUTION:When the sentence of the morphology of a natural language is inputted, a morphological element analysis for dividing to the morphological elements of the stem of a word and the ending of the word is executed, thereafter, the syntax is analyzed. Then, from the obtained syntactic analysis result, the collating destination is extracted and when a noun or a demonstrative noun capable of being collated or an omission appears, whether it is collated to the noun appearing in the past context or not is examined. When all the collating destinations are extracted, if the candidates of some interpretations are guided, according to the combination thereof, the ranking processing based on the limit of the concept dictionary is executed to output the candidate high in a priority. Thereby, even when the extracted candidate of the collating destination violates the limit information described in the concept dictionary, an interpreting candidate including the collating destination is not rejected but the priority is only lowered and outputted to obtain a most suitable interpreting candidate.

Filed: 1999-01-21
Abstract: PROBLEM TO BE SOLVED: To positively store data such as measured values by detecting a momentary power failure or power interrupt and to take reliable measures for the power interrupt at its occurrence. SOLUTION: A power interrupt detecting circuit 5 inputs the instantaneous value of a line voltage digitized by a voltage converting circuit 2 to detect instantaneous power failure or power interrupt, based on the extent of the voltage drop and the duration of drop time of its absolute value. Upon receiving the output of this detection, a CPU 8 makes data such as the measured values to be at stand-by and stored in a storage circuit 9. Power supply circuits 4, 7 supply DC power from the line voltage to each circuit and another power interrupt detecting circuit 6 detects a power interrupt by the voltage drop of the power supply voltage 4. Upon receiving the output of this detection, the CPU 8 takes measures for the power interrupt to stop the operation of each circuit.  When a backup power supply is provided, measures such as lowering the operation speed of the CPU 8 for lowering that of the each circuit are taken to reduce power consumption at power interrupt.

Abstract: PURPOSE:To prevent etching residuals of a gate conductive layer from remaining to improve structural and electric characteristics of a silicon circuit board by buffering difference in level of a field oxide film formed at edges of a nitride film by means of argon sputtering in removing a thin oxide film. CONSTITUTION:A pad oxide film 2 for protecting a transistor region is formed, a nitride film 3 is formed on a region which is not to be field-oxidized on a silicon substrate 1, and then the substrate 1 is subjected to thermal oxidation to form a field oxide film 4 on a region not covered by the nitride film 3. An oxide film 5 is formed also on the nitride film 3 at this time. This film 5 is removed and then the nitride film 3 is removed so that the field oxide film 4 suffers from difference in level 6 at edges of the nitride film 3. When sputtering is done with argon flowing to the field oxide film 4, the transistor region is protected by the pad oxide film 2, but the difference in level is buffered. Therefore in subsequent formation process of a gate conductive layer 7, remaining of residuals can be eliminated and short-circuiting between transistors can be prevented.
