Abstract: A document retrieval assistance method has a user interface with an interactive guidance function. In response to a search query, search results including a title list of retrieved documents is displayed alongside a separate display of topic words extracted from the retrieved documents which reflect the search results. In particular, a topic-word graph is displayed alongside a list of titles of the retrieved documents and the interface enables browsing of the documents using the topic words. Further, the interface permits emphasized display of the list of titles of the documents through direct selection of the titles displayed in the list or through selection of the topic words. Further, an associative search can be executed using a selected document to refine the original search results and develop updated displays of the search results and topic words contained in the documents.

Abstract: Achieving efficient analysis of search results, which is required for the examination of search queries, by listing up both title information of a retrieved document group and the whole information.

Abstract: A polyimide film having sufficiently excellent characteristics such as a sufficiently high elastic modulus, a low water absorption, a small coefficient of moisture-absorption expansion, a small coefficient of linear expansion and a high dimensional stability; and various electric/electronic equipment bases with the use of the polyimide film. A polyimide film having a tensile elastic modulus of 700 kg/mm2 or less and a coefficient of moisture-absorption expansion of 20 ppm or less and containing a specific repeating unit as an essential repeating unit is synthesized. Then various electric/electronic equipment bases such as a laminate for flexible print connection boards are produced by using the polyimide film.

Abstract: An object of the present invention is to provide a stable pharmaceutical composition for topical administration comprising minocycline as an active ingredient. According to the present invention, there is provided a pharmaceutical composition for topical administration comprising minocycline or a physiologically acceptable salt thereof in an oleaginous base.

Abstract: A fluoro-carbon resinous laminate has a crack-resistant surface on a fluoro-carbon resinous layer thereof produced by coating a single surface or both surfaces of a plastic film with a single layer of a fluoro-carbon resinous dispersion, and a method of producing the laminate. To produce the fluoro-carbon resinous laminate, which is a minimum of 10 .mu.m in thickness, a single surface or both surfaces of a plastic film are coating with a single layer of concentration-adjusted fluoro-carbon resinous dispersion and then dried, followed by curing the resinous dispersion in a thermal treating furnace with heated atmospheric air or by adding organic solvent to the resinous dispersion, the enabling production of a fluoro-carbon resinous laminate having a surface appearance in which cracks cannot visually be identified.

Abstract: A composition for local anesthesia which comprises (A) lidocaine, (B) a catecholamine such as epinephrine in an amount of, for example, 1/200,000 (g/ml) based on the volume of the composition, and (C) one or more amino acids such as glycine, glutamic acid, and L-glutamic acid-L-lysine or one or more hydroxycarboxylic acids such as lactic acid, glycolic acid, and citric acid, which has a duration suitable for short-time dental operations such as tooth extraction and excellent storage stability.

Abstract: An aqueous pharmaceutical composition comprising sodium cromoglicate as an active ingredient and a quaternary ammonium compound such as benzalkonium chloride as a preservative, characterized in that said composition comprises a precipitation inhibitor selected from the group consisting of alkanolamines including 2-aminoethanol and tocopherols including d-.alpha.-tocopherol is provided. The composition has characteristic feature of free from precipitation or turbidity in manufacturing processes and during storage.

Abstract: A voice reproducing apparatus for personal use is provided with a card serving as a memory-unit accommodating member incorporating therein a memory unit which stores voice as compressed codes; a player body for converting the codes to a voice signal and incorporating therein an interface, a decoding unit, and a circuit portion; and an earphone. The earphone is connected to said card, some of a plurality of contacts of a terminal portion provided in said card are formed as contacts of a terminal portion for an earphone, some of a plurality of contacts of a terminal portion provided in said interface of said player body are formed as contacts of an output terminal portion, and said terminal portion for an earphone is connectable to said output terminal portion when said card is loaded in said player body.

Abstract: A process for producing a cellulose ester support is described which comprises producing said support from an organic solvent solution of a cellulose ester containing 30 ppm or less alkaline earth metal.
