A system and method for detecting preference expressions indicating evaluators' likes and dislikes of a product from evaluations of the product and stores text describing evaluation of the product in association with an attribute of the text. The method extracts an evaluating expression describing evaluation of the specific object from each of the texts, determines whether the extracted evaluating expression has positive or negative polarity, where the positive indicates favorable evaluation and the negative indicates unfavorable evaluation. The system inputs a text attribute that is designated as an object for detecting the preference expression and detects an evaluating expression, which is detected from a text having an input attribute from the extracted evaluating expressions as one of the preference expressions and outputs the preference expressions in association with a frequency of the preference expressions being determined to have the positive or negative polarity in the text having the attribute.

A swash plate of a swash-plate compressor is subjected to sliding on shoes and is required to have excellent seizure resistance and wear resistance under the dry lubricating condition. The swash plate according to the present invention is provided with the surface-treated layer, i,e., the intermediate layer consisting of Cu, Sn or metal phosphate, and a sliding contact layer consisting of MoS.sub.2 and/or graphite and thermosetting resin.

A lip seal device for sealing the gap between a housing and a rotary shaft comprises a case surrounding the rotary shaft, a lip seal attached inside the case a, support for holding the lip seal on the outer circumferential portion thereof and a seal located on the outside circumferential surface of the case. The inner circumferential portion of the lip seal is curved toward the sealed fluid. The lip seal includes a sealing surface provided with an annular groove extending continuously in the circumferential direction of the rotary shaft so that the sealing surface has a first and second sealing portion, the contact pressure of the first sealing portion on the rotary shaft being lower than the contact pressure of the second sealing portion on the rotary shaft.

A lip seal device for sealing the gap between a housing and a rotary shaft comprises a case surrounding the rotary shaft, and a lip seal located on the case and curved toward a sealed fluid and having a sealing surface in sliding contact with an outer circumferential surfaces of the rotary shaft. The lip seal device includes a seal member on the seal surface for sealing a gap between the seal surface and the rotary shaft. The seal member includes a primary annular groove and an auxiliary seal means. The primary annular groove extends continuously in the circumferential direction of the rotary shaft. The auxiliary seal means, either projections or grooves are provided adjacent to the primary annular groove.

A data transfer device that confirms completion of writing into a memory on transferring data to the memory via a bus through which a response indicating completion of data writing in the memory is not sent back includes an inter-memory data transfer control unit performing data transfer between the memories. When the inter-memory data transfer control unit detects switching of a write destination memory from a first memory to a second memory, in order to confirm that writing into the first memory is completed, the inter-memory data transfer control unit performs confirmation of write completion as to the first memory by a procedure different from writing into the memory. When a data transfer with a designated transfer length is completed, in order to confirm that writing is completed as to the write destination memory at the end of the data transfer, the inter-memory data transfer control unit performs confirmation of write completion as to the write destination memory at the end of the transfer by the procedure different from writing into the memory. The inter-memory data transfer control unit notifies the processor of completion of an inter-memory data transfer based on the confirmation of write completion.

In order to solve the above problem, disclosed as a first aspect is a method including the steps of analyzing a character string in a document into partial character strings; calculating, with respect to each of the partial character strings, a score incorporating appearance frequency of the partial character string; presenting the partial character strings and the scores to a user; determining which ones of the partial character strings have been selected by the user; storing the selected partial character strings as a safe partial character string list; and replacing, with predetermined replacement character strings, the partial character strings excluding the partial character strings existing in the safe partial character string list.

Provided is an expression extraction device for extracting evaluation expressions from text having descriptions on evaluations of a specific evaluation target, which includes a registered expression storage unit for registering an evaluation expression including a predetermined polarity as a registered expression, an expression extraction unit for extracting multiple evaluation expressions and a conjunction expression from the text, a registered expression detection unit for detecting the evaluation expression including the registered expression registered with the registered expression storage unit out of the multiple evaluation expressions, and a polarity judgment unit for judging that the evaluation expression, which is in conjunction with the evaluation expression including the registered expression by means of the conjunction expression in a form of ordinary conjunction, and the series of evaluation expressions, which are not in conjunction with the evaluation expression by means of the conjunction expression in any form of the ordinary conjunction and adversative/concessive conjunction and are not in conjunction with each other by means of the conjunction expression in any form of the ordinary conjunction and the adversative/concessive conjunction, are of the same polarity as the registered expression.
摘要:
A slide member which is excellent in the initial running-in property and can provide an excellent sliding property even under a strict sliding condition and, in particular, a slide member with a solid lubrication coating film which is excellent not only in the friction property but also in the wear resistance under the fluid lubrication, boundary lubrication and dry lubrication conditions. The slide member includes a solid lubrication coating film on a flat-plate-shaped base member, characterized in that, in the surface of the slide member, there are formed a plurality of concentrical grooves extending in the peripheral direction of the slide member surface, and, between the mutually adjoining ones of the grooves, there are formed ridge portions respectively.

A lip seal device for sealing the gap between a housing and a rotary shaft comprises a case surrounding the rotary shaft, a lip seal attached inside the case, support means for holding the lip seal on the other circumferential portion thereof and seal means located on the outside circumferential surface of the case. The inner circumferential portion of the lip seal is curved toward the sealed fluid. The lip seal includes a sealing surface provided with an annular groove extending continuously in the circumferential direction of the rotary shaft so that the sealing surface has a first and second sealing portion, the contact pressure of the first sealing portion on the rotary shaft being lower than the contact pressure of the second sealing portion on the rotary shaft.
