摘要:
A method for producing a glass preform comprising flame hydrolyzing a glass raw material in an oxyhydrogen flame to form glass fine particles of quartz, depositing the glass fine particles on a seed member to produce a solid or hollow cylindrical soot preform at least of a part of which contains GeO.sub.2, and heating and sintering the soot preform by introducing it in an atmosphere comprising an inert gas at least a part of which is kept at a temperature not lower than 1,600.degree. C. at an introducing rate not smaller than 3 mm/min, from the glass preform produced by which method, an optical fiber having longitudinally homogeneous composition and low attenuation of light transmission is fabricated.
摘要:
Fluorine is selectively added to a cladding portion of a glass preform by producing a soot preform which comprises a core portion and a cladding portion under such conditions that an additive concentration or a bulk density of the outermost part of the core portion is to be larger than that of the inner part thereof and heating the soot preform in an atmosphere containing fluorine or fluorine-containing compound at least for some period to obtain a transparent glass preform.

Destination input devices, methods, and programs that store a plurality of destination data items and a plurality of related terms related to the destination data items, a plurality of generic names associated with each of the related terms. The devices, methods, and programs select at least one of the destination data items that are stored in a memory based on an ordinary search of the character that is input as the search key, extract one of the related terms, the generic names, and the destination data items based on a fuzzy search of the character that is input as the search key; and display in list form, search results that correspond to the character that is input, the generic names that are selected by the fuzzy search and the at least one of the destination data items that is selected by the ordinary search.
摘要:
A common word in Japanese syllabary is extracted from multiple items of the destination data, and the common words thus extracted are stored as search keywords. Furthermore, the search keywords are assigned to each potential destination which may be a search target. When a search is made for a destination, those keywords which match the input characters, in whole or in part, are extracted, and the keywords thus extracted are displayed as selectable keys, thus allowing the location candidates to be narrowed down based upon the input characters and the selected keywords. The priority levels of the extracted location candidates are adjusted according to priority score adjustment rules set by operator input, and the location candidates are displayed in the form of a list in descending order of priority. This allows the extracted location candidates to be displayed in the form of a list in an order matching the user's preference.
摘要:
A data processing center includes a receiver that receives a present position of a portable terminal transmitted from the portable terminal, at least one controller that determines a moving means that is moving the portable terminal based upon the present position and retrieves data related to the determined moving means, and a transmitter that transmits the retrieved data related to the determined moving means to the portable terminal.

Disclosed herein are methods and means of producing novel growth hormone-like proteins derived from the pituitary gland of fishes belonging to the order Pleuronectina, the family Paralichthydae, which are useful in the growth promotion for fishes, by genetic engineering using cloned genes.
摘要:
A fish growth hormone provided by a purified extract obtained from the pituitary gland of a fish belonging to salmonoid; the hormone is a polypeptide having the following physicochemical properties:(i) amino acid composition: as indicated in Table 1;(ii) the sequences of 33 amino acids at the N-terminal and 23 amino acids at the C-terminal are as follows:N-terminal: H.sub.2 N-Ile-Glu-Asn-Gln-Arg-Leu-Phe-Asn-Ile-Ala-Val-Ser-Arg-Val-Gln-His-Leu-His-Leu-Leu-Ala-Gln-Lys-Met-Phe-Asn-Asp-Phe-Asp-Gly-Thr-Leu-Leu-C-terminal: -Met-His-Lys-Val-Glu-Thr-Tyr-Leu-Thr-Val-Ala-Lys-Cys-Arg-Lys-Ser-Leu-Glu-Ala-Asn-Cys-Thr-Leu-OH;(iii) molecular weight: about 22,000;(iv) isoelectric point: 5.6-5.7; and(v) soluble in an alkaline aqueous solution and hardly soluble or insoluble in neutral and acidic aqueous solutions.
摘要:
A searching device that includes an input string acquisition unit that acquires an input string input by a user; a predicted candidate string extracting unit that extracts a predicted candidate string that begins with the input string; a deleted character determining unit that acquires a deleted character deleted from the input string, and that determines a deleted character position that is a character position of the deleted character in the input string; and a changing unit that, on the basis of the deleted character and the deleted character position, changes a priority of the predicted candidate string that begins with the input string from which the deleted character has been deleted.
摘要:
An optical element includes an optically effective area and an optically ineffective area partly or entirely coated with a coating opaque at wavelengths used. The opaque coating contains a cured product prepared from an epoxy resin and a curing agent containing an alicyclic acid anhydride. The alicyclic acid anhydride is preferably methylhexahydrophthalic anhydride or hexahydrophthalic anhydride.

Search devices, methods, and programs accept an input of a first character string for searching for a search object and store second character strings. The devices, methods, and programs search among the stored second character strings for a second character string who's beginning matches the input first character string. The devices, methods, and programs display the found second character string, excluding from the display any of the found second character string for which a number of subsequent input operations that equals the difference between the number of characters in the found second character string and the number of characters in the input first character string is less than or equal to a number of operations to select the found second character string. When one of the displayed second character strings is selected, the devices, methods, and programs a display a search object that corresponds to the selected second character string.
