摘要： PROBLEM TO BE SOLVED: To stiffen a lap winding end portion low in lap stiffness in particular, which is located at a place where intake gas is enclosed by a turning scroll, by locally thickening the lap outer line outwardly in the radial direction at a place where the winding end portion of a turning scroll lap outer line is located. SOLUTION: A turning scroll 5 to be incorporated with a compression mechanism part has a lap winding end portion 5f thickened for example, in a range of 5h outwardly in the radial direction at a place out of a turning scroll lap outer line position 5g where intake gas is enclosed while being formed together with a stationary scroll inner line out of the two most hermetic chambers. Therefore, in a compression stroke by the turning scroll and the stationary scroll when intake gas is enclosed, strikes are reduced between the winding end portion of the turning scroll inner line and the winding end portion of the stationary scroll outer line, and an increase in input caused by lap striking and the degradation of reliability due to lap rupture caused by lap striking are thereby improved.

摘要： PURPOSE:To utilize viscosity pumping effect with the rotation of a rotor itself, filling the required section with stable oil at all times and prevent gas leakage from a rotor deddendum section to the side of a bearing by forming a spiral groove on a shaft orthogonal with the edge of a rotor tooth. CONSTITUTION:Low-temperature and low-pressure refrigerant gas sucked from the side of a drive motor 16 is compressed by reducing the geared tooth profile space of a pair of male and female rotors 2 and 3 housed in a casing 1. Also, for compressing reaction in compression stroke, a thrust load is supported with ball bearings 11 and 12, while a radial load is supported with roller bearings 10, 13, 14 and 15. Also, oil is fed from an oil chamber exposed to delivery gas to a rotor deddendum shaft via an oil passage 23. In this case, a spiral groove 22 is formed on the rotor deddendum shaft section. Also, oil is fed from an oil groove 21 toward a tooth edge, with pumping effect available from the rotation of a rotor in the compression stroke. According to the aforesaid construction, a gap between the rotor deddendum shaft section and D-cover 4 as the enclosure thereof, and a casing inner surface is always filled with oil.

摘要： PURPOSE:To form a translated sentence expressed close to the meaning of an original by forming expressing distinctions such as Chinese word/Japanese word in translated word information of a dictionary and providing a selecting function for the distinctions. CONSTITUTION:An English sentence inputted from an input part 1 is divided into words and syntax analysis is executed by a translation processing part 2 based on word information in a dictionary file 4 and grammar information in a grammar file 5. Simultaneously, the expression of translated words is specified (Chinese word/ Japanese word) from the input part 1 to a translated word selecting part 3. Then, a translated word is selected from a translated word range narrowed up to a certain level by determining the parts of speech or other attributes by the syntax analysis. The sorts of expression of words are previously specified in the selecting part 3 such that Chinese expression is used for a sentence with formal expression such as a technical sentence and a manual sentence, and Japanese expression is used for a sentence with soft expression such as a letter sentence, so that the selecting part 3 selects translated words in accordance with the determination and combines the same word groups to form the translated sentence.

摘要： PURPOSE:To reduce post-processing by storing the Japanese translation and 'KATAKANA' (square form of Japanese syllabary) translation for foreign language words and selecting the 'KATAKANA' translation with priority by using information for identifying the 'KATAKANA' translation in response to a specification. CONSTITUTION:A translation program 6 in a machine translation system 5 in a CPU 4 processes an original text 8 based on translation regulation in a dictionary 9 and a memory 7 and outputs a translation text 10. Analyzing information for foreign language sentences and Japanese sentence forming information are registered in the dictionary 9. Exclusive codes are added to the 'KATAKANA' translation in the dictionary 9, and when a user specifies the output of the 'KATAKANA' translation, the program 6 selects the translated words having the exclusive codes with priority.

摘要： PROBLEM TO BE SOLVED: To shorten the time needed to gather candidates for a word to be registered in a dictionary and the time needed to input equivalents to the word by performing retrieval based upon a key word, automatically gathering text data of a specified field, and extracting the word to be registered in the dictionary from them. SOLUTION: A gathering process part 2 gathers the text data with the key word. Consequently, candidates for the word to be registered in the dictionary can be gathered from English text data and Japanese text data of some specified field. An extracting process part 3 extracts KATAKANA (square form of Japanese syllabary) notation from the gathered Japanese text data. A converting process part 4 finds a set of candidates for the spelling of English from the extracted KATAKANA notation by using a conversion table 5. An equivalent retrieving process part 6 matches the set of candidates for the English spelling against the gathered English text data to extract an equivalent. Consequently, equivalents can automatically be given to the gathered words.

摘要： PROBLEM TO BE SOLVED: To reduce costs for individually integrating a retrieval supporting system into plural retrieving systems on a network. SOLUTION: When a data obtaining command is transmitted from a client, a dictionary retrieval interface applying means 114 in a dictionary retrieval interface applying device 102 returns the actual data acquisition command and an extending function data acquisition command to the client when the data acquisition command is made coincident with the record of an identifier storage area 105. When the both commands are transmitted from the client, an extending function data acquisition 118 retrieves a retrieving server, and obtains data according to the actual data acquisition command, and generates extending function data and returns it to the client according to the extending function data acquisition command. The client generates a dictionary retrieval interface based on the returned extending function data.
