Title: Exhaust gas emission control device for internal combustion engine
Inventor: HIROTA SHINYA
IPC: F01N3/28
Filed: 1999-02-22
Abstract: PROBLEM TO BE SOLVED: To improve reliability on purification of exhaust gas, in an exhaust gas emission control device provided with an NOx catalyst and a bypass passage bypassing the NOx catalyst. SOLUTION: A NOx absorbing agent 20 on the downstream side and a bypass pipe 26 bypassing a NOx catalyst 20 on the downstream side are arranged downstream from an NOx catalyst 17 on the upper stream side. An exhaust gas switching valve 28 to switch the flow of exhaust gas is arranged at the starting end part of the bypass pipe 26. When SOx is emitted from the NOx catalyst 17 on the upper stream side, exhaust gas is guided to the bypass pipe 26, and exhaust gas is prevented from a flow to the NOx catalyst 20 on the downstream side. When SOx is not emitted from the NOx catalyst on the upper stream side, exhaust gas is guided to the NOx catalyst 20 on the downstream side and the exhaust gas switch valve 28 is controlled such that exhaust gas is prevented from a flow to the bypass pipe 26.  Even when, during no emission of SOx, exhaust gas leaks to the bypass pipe 26, exhaust gas is already purified by the NOx catalyst 17 on the upper stream side before the exhaust gas flows in the bypass pipe 26, whereby exhaust gas emission is prevented from worsening.

Title: Magnetic disk apparatus and method for detecting failure of head
Inventor: ITO HIROSHI
IPC: G11B19/04
Filed: 1997-02-27
Abstract: PROBLEM TO BE SOLVED: To detect a break of a head before a fatal state. SOLUTION: At a production stage of a magnetic disk apparatus, values of (A-B)/(A+B) and (C-D)/(C+D) are calculated from amplitudes of burst signals A, B and burst signals C, D reproduced by a head. The head is positioned at a position where the values agree. An absolute value of the calculated value is registered as a head abnormality judgment reference value S in an EEPROM. After the apparatus is shipped, at an initialization process consequent to the supply of a power source, the head is moved to a position where the values (A-B)/(A+B) and (C-D)/(C+D) agree (step 801), and an absolute value X of the value at the time and the reference value S in the EEPROM are compared. If a difference is not smaller than a predetermined value Δth, the head is judged to be abnormal (steps 802, 803), and the fact is informed to a host apparatus (step 804).

Abstract: PURPOSE:To realize the generation of key words with emergence of a compound word, a derivative, an abbreviation, a synonym, a relative word, etc., of a word in a key word dictionary by performing the collation for partial coincidence between the words of the key word dictionary and an object sentence. CONSTITUTION:A dictionary collation part 6 performs the collation for partial coincidence between a word extracted out of the object sentence and a word in a key word dictionary 5. Then the total contents of a sentence are analyzed based on the degree of correspondence between the words in the object sentence and the dictionary 5, the degree of importance of the word in the object sentence serving as a key for the extraction of the key word candidates, and the degree of relation between the word in the object sentence and a key word candidate. Thus a key word is obtained. Thus it is possible to produce a key word with the use of a word containing a character string having the partial coincidence with the relative compound word, derivative, abbreviation, etc., used as a key even when the object sentence includes no word that is not completely coincident with the word in the dictionary 5. In addition, such words that show properly the total contents of a sentence or shows the important contents of the sentence can be produced as the key words.
