Filed: 1986-01-31
Abstract: PURPOSE:To unify the words in a document with high efficiency by picking up the words of similar expressions out of the document displaying these words with underlines or in a list. CONSTITUTION:For instance, the sentences of similar expressions are included in those sentences produced by a document producer and as shown in a list. To pick up these sentences, an indication is given from an input part 1 for retrieval of synonyms against 'UTSUSU' of a sentence 1'. Then an analysis part 2 receives the key data and gives 'UTSUSU' to a control part 4 together with an indication for retrieval of synonyms by a synonym retrieving part 5 retrieves the candidate synonyms of 'UTSUSU' at and after a sentence. While a morpheme analysis part 6 recognizes that 'UTSUSU' is the stem of a verb 'UTSU' (5-conjugation/SA-series) with reference to a dictionary 8. Furthermore a grammar analysis part 9 judges that 'UTSUSU' shows an end form. Then a synonym extracting part 7 extracts the candidate synonyms out of the dictionary 8 and retrieves them out of the character strings in the document.

Title: Variable speed controller for induction motor
Inventor: SASAGAWA KIYOAKI
IPC: H02P21/18
Filed: 1988-02-01
Abstract: PURPOSE:To prevent fault of a variable speed drive system due to fault of a speed detector, by employing an output from a speed operating means as a speed detection value when the speed detector is abnormal. CONSTITUTION:A fault judging circuit 23 monitors the state of a speed detector and outputs a fault signal upon judgement of fault. A speed operating circuit 21 estimates speed through operation. A switching circuit 22 switches a speed amount omega''2 to be employed in a controller from an output omega2 of the detector to an output of a speed operating circuit, i.e., an estimated speed omega'2, corresponding to a fault signal. When an output from the speed operating means is employed as a speed detection value upon occurrence of abnormality in the speed detector, the reliability of control system can be improved.

Title: Method for calculating form coefficient between faces of object having optional shape
Inventor: MATSUSHIMA HITOSHI
IPC: G06F17/10
Filed: 1992-02-05
Abstract: PURPOSE:To calculate a form coefficient between the faces of an object having an optional shape with the practically satisfactory time and accuracy when a radiation heating analysis is carried out with an obstacle included in a space by subdividing a face element only when the distance between both faces is less than a threshold value. CONSTITUTION:The center distance is calculated between two selected faces 1 and 2 together with the area of each face. Then a marker is shifted to one of both sides to the other on a straight line connecting together the centers of both faces 1 and 2. A flag is added to a solid element existing between both faces to identify a fluid or a solid matter. When the marker enters the solid element having a solid flag before reaching the other face, the value of the form coefficient existing between both faces set at '0' and the combination with the other face is calculated. When the marker reaches the other face, the square of the distance between both faces is compared with the ratio of the larger one of both face areas. If this comparing result is larger than a certain threshold value, the form coefficient is calculated by using an AI method without subdividing the face element.

Title: Magnetic tape controller

IPC: G11B20/12
Filed: 1981-02-13
Abstract: PURPOSE:To prevent an inrush to reposition sequence, by inserting a dummy data to which a discriminating code has been added, by a specific means, even if an external data has been interrupted, in case when a data is stored in a streaming mode. CONSTITUTION:A data from a CPU is sent to a dummy data inserting circuit 305 through a signal line 4 and an interface circuit 300. A signal line 302 becomes logical ''0'' while a data transfer is interrupted, a DET 303 measures a data interrupted time, and sends out an interrupting signal of logical ''1'' for a constant interval of time. The circuit 305 is constituted so that a discriminating code C is added to a data while 304 is logical ''0'', and a dummy data to which a discriminating code C' has been added is outputted continuously onto a signal line 306, while it is logical ''1''. As a result, the storage device executes storage at a high speed without entering reposition sequence. In case when the CPU reads, a decoding circuit 402 detects the discriminating code, and passage of the codes C, C' and the dummy data is inhibited by a gate circuit 405.

Filed: 1981-02-13
Abstract: PURPOSE:To take a photograph of vibrating mode of a revolving body at highly accurate timing by a light stimulation signal generator operating at pulse in correspondence with a pulse generator and a revolving body under test, and a Q- switch trigger signal generator. CONSTITUTION:A revolving pulse signal 16 itself is used as a Q-switch signal 22. The revolving angle and position of a revolving body 1 is made constant at the time of laser emission twice by a laser oscillator 13, even if the revolving body 1 varies in revolving speed. The holography can be photographed without discrepancy. The optimum time for light stimulation of the laser oscillator 13 is subtracted from the revolving period of the revolving body 1. And, a setting circuit 11 is set by obtaining the counting number from the oscillating frequency of a pulse oscillator 6. The pulse number of a counting signal 18 is counted with a counter 9 by turning a control circuit 8 ON. An equal signal 19 is output when the counting number set comes. A pulse stretcher 12 outputs a light stimulation signal 20.

Title: Wiring connecting structure for semiconductor device
Inventor: SHIGEMATSU YASUHIRO
IPC: H01L21/3213
Filed: 1986-01-30
Abstract: PURPOSE:To prevent the wiring of a semiconductor device from being overetched at the time of opening a contact hole in a contact hole forming portion for connecting between upper and lower wiring layers by interposing an etching preventing layer under the lower wiring layer. CONSTITUTION:First wirings (gate electrode) 14 are extended on a first insulating film (field oxide film) 12 on a semiconductor substrate 11, and connected through contact hole 17 with second wirings (upper layer wirings) 18 on a second insulating film (interlayer insulating film) 15. An etching preventing layer (silicon nitride film) 16 is formed on the film 12 at the position corresponding to the hole 17. Thus, even if the position of the hole 17 is displaced from the position on the wirings 14, the fact that the film 16 has arrived at the hole 17 at etching time can be judged due to a variation in a reactive product, thereby detecting the end of the etching. Then, it can prevent the wirings from being overetched to the film 12.

Abstract: PURPOSE:To realize gettering in an SOI substrate and obtain a device which has few crystal defects and has excellent device characteristics by a method wherein oxygen diffusion blocking films are formed on the regions of a polycrystalline silicon layer other than device forming regions and, in this state, the polycrystalline silicon layer is melted and recrystallized to form the SOI substrate and the substrate is subjected to successive heat treatments under a high temperature, a medium temperature and a high temperature. CONSTITUTION:An insulating film 3 is formed on a silicon substrate 1 and a polycrystalline silicon layer 4 is formed on it. After oxygen diffusion blocking films 5 are formed on the regions of the polycrystalline silicon layer 4 other than device forming regions, the polycrystalline silicon layer 4 is melted and recrystallized in this state to form an SOI substrate. The formed SOI substrate is subjected to successive heat treatments under a high temperature, a medium temperature and a high temperature for predetermined periods to diffuse oxygen in the parts of the silicon substrate 1 directly under the device forming regions outside. Further, oxygen is deposited in the parts of the polycrystalline silicon layer 4 directly under the oxygen diffusion blocking films 5 to form cores of fine defects and, by making the cores grow, crystal defects for intrinsic gettering can be formed directly under the oxygen diffusion blocking films 5.
