An index generating apparatus acquires values corresponding to a plurality of respective attributes of a number that appears in a piece of target text data. The index generating apparatus then maps the values corresponding to the respective attributes to value ranges of the respective attributes. The index generating apparatus then generates a bitmap index indicating bitmap data in which a position at which the number appears is mapped to each of a plurality of value ranges.

A non-transitory computer-readable medium including a program, which when executed by a computer, causes the computer to execute a process including collecting data item indicating specific criteria relating to a plurality of rules for gradually filtering a received data; and selectively extracting specific data relating to the collected data item indicating the specific criteria from content of the received data.

Medium, method, and apparatus

An encoding device searches input text data for a date-time notation string that represents at least a date or time. The encoding device generates, upon finding the date-time notation string by the search unit, a converted date and time code including an identification code for identifying the date-time notation string and a normalized date and time notation formed by converting the date-time notation string into a specific date-time notation format. The encoding device converts the input text data based on conversion information that associates the converted date-time code generated by the generation unit with the date-time notation string.

Encoding method and encoding device

A storage unit stores rule information that includes information indicating a plurality of operations based on event data. A computing unit searches the rule information to find information indicating a first operation, information indicating an operation of a condition determination that is executable regardless of the result of the first operation, and information indicating a second operation that is associated with the condition determination and uses the result of the first operation. The computing unit generates control information for controlling the execution order of the operations such that the first operation is executed in accordance with the result of the condition determination and such that the second operation is executed after the first operation. When the event data is input, the computing unit executes an operation corresponding to the input event data, based on the control information.

Program, information processing apparatus, and event processing method

A message processing apparatus which handles messages exchanged over a network and explicitly notifies the recipient of the importance and other information regarding each received message. Incoming messages are received by a receiver employed in the apparatus. Those messages may contain some key information as part of their attribute data, which specifies a handler program relevant to them. A key information extraction unit extracts the key information from each received message. Consulting a table that defines the relationships between handler programs and various key information, a program loading unit then loads a specific handler program relevant to the extracted key information. The recipient may cause an event related to the received message. Depending on what kind of event it is, an execution unit chooses and executes an appropriate primitive process provided as part of the handler program. When, for example, the recipient attempts to delete an unopened message, the apparatus will warn him/her by displaying a warning message on a monitor screen.

Message processing apparatus

A problem solving operation apparatus obtains an optimum solution for a given problem through a combined use of a plurality of optimum solution search techniques of a genetic algorithm, and other search techniques like a hill climbing method. A combination of the optimum solution search techniques applied to each of a group of solution candidates varies according to each state. When a search efficiency in a single state is lowered, the problem solving operation apparatus immediately causes a state transition to the next state, thus enabling a search of an optimum solution through the use of another combination of more efficient optimum solution search techniques. Because a state transition constantly maintains a high search efficiency, this problem solving operation apparatus can reach an optimum solution in a short amount of time.

Problem solving operation apparatus using a state transition

A video presentation system is provided which permits a process in which, when an object in motion video image is handled, an action relating to the object is executed, without increasing load on a central processing unit or a memory. Subject-of-operation information, which defines objects to be handled by a user in relation to each of frames of video data at a transitional phase of time-varying motion of each object, is stored in video operation information retaining means, and when a user operation takes place, the frame position of a currently reproduced video image is acquired from video driving/processing means while screen coordinates of the object are acquired from a coordinates specifying device. Based on the acquired data, video operation information processing means searches the subject-of-operation information to identify the object handled by the user. The subject-of-operation information retains only information associated with each transitional phase of motion of the object, whereby the size of information can be reduced, thus permitting the object specifying process and a like process to be executed at high speed.

Video presentation system

The inventive method comprises the steps of coating the substrate surface with a coating solution containing .beta.-diketone complex of a metallic element in an aprotic polar solvent, drying and irradiating the coating film on the surface with ultraviolet light, optionally, followed by a heat treatment to form an electrically insulating oxidized metal film on the surface. By virtue of the ultraviolet irradiation, the oxidized metal film can be imparted with increased insulation even by omitting the heat treatment or by decreasing the temperature of the heat treatment so that the adverse influences on the characteristics of the substrate can be minimized.

Method for forming a film of oxidized metal

A coating solution for forming a silica-based film, having a given viscosity, is coated on a substrate such as a silicon wafer, this coating solution is dried to form a silica-based film, and this silica-based film is exposed to ultraviolet radiation in an atmosphere containing ozone at room temperature or while heating it preferably at a temperature of not more than 300.degree. C., particularly at a temperature of from 50.degree. to 200.degree. C., by means of a heating member such as a hot plate. The film quality of the silica-based film can be improved by exposing it to ultraviolet radiation in the atmosphere containing ozone.

Method for improving film quality of silica-based films

A silicone film is formed by drying a solution coated on a substrate at a temperature below 150.degree. C. to form a silicone film on the substrate, treating the silicone film in an oxygen plasma, and heating the silicone film treated in the plasma at a temperature of 150.degree. C. or higher.

Method of forming silicone film

The adhesiveness of a silicone-based coating film on a substrate to an overcoating layer, e.g., a photoresist layer, can be improved without causing cracks when the silicone-based coating film is subjected to a plasma treatment at a temperature of 120.degree. C. or below in an atmosphere of a gas mainly composed of oxygen. Similar conditions of plasma treatment are applicable when patterning of a silicone-based coating film is desired in a procedure comprising the steps of forming a photoresist layer thereon, patterning of the photoresist layer in a photolithographic method, selectively etching the silicone-based coating film with the patterned resist layer serving as a mask and removing the photoresist layer by the plasma treatment.

Surface treatment of silicone-based coating films

The coating solution of the invention is useful for forming a silica-based coating layer on a substrate such as semiconductor silicon wafers in the manufacturing process of semiconductor devices such as VLSIs. The coating solution is particularly advantageous to smooth a substrate surface having a difference in levels by completely filling the recessed areas. The coating solution is an organic solution of a cohydrolyzate of an alkoxy silane mixture composed of at least two kinds of di-, tri- and tetraalkoxy silane compounds such as a combination of methyl trimethoxy silane and tetramethoxy silane in a specified molar ratio and can be prepared by adding water to an organic solution of these alkoxy silane compounds without using any acid catalyst to effect the cohydrolysis of the silane compounds.

A liquid coating composition for forming a silica-based coating film on the surface of a substrate such as a semiconductor silicon wafer. A partial hydrolysis product of an alkoxy silane and an alkoxy or phenoxy compound of pentavalent antimony are dissolved in an organic solvent. As compared with a trivalent antimony compound used in the prior art, the pentavalent antimony compound as an additive is very effective in respect of the improvements in the uniformity and increased thickness of the silica-based coating film prepared from the coating composition as well as storage stability of the coating composition over time.

Liquid composition for forming silica-based coating film

An improved silica-based film-forming composition for diffusion of antimony in the doping works of semiconductors is proposed which comprises an organic solvent, a partial hydrolysis product of an alkoxy silane compound and an antimony compound dissolved in the organic solvent. The antimony compound in the inventive composition is an alkoxy antimony or aryloxy antimony compound so that the problem of corrosion of the coating apparatus can be entirely avoided without decreasing the dopant concentration in the semiconductor substrate, as well as to provide a film-forming composition which is advantageously stable in storage.

Silica-based antimony containing film-forming composition

The invention provides a novel means for providing a highly heat-resistant and corrosion-resistant coating film on the surface of a substrate such as a semiconductor silicon wafer or glass plate by coating the surface with a liquid coating composition which is a solution of an oligomeric organopolysiloxane as a partial dehydration-condensation product of a monohydrocarbylsilane triol RSi(OH).sub.3, optionally, with admixture of a dihydrocarbylsilane diol R.sub.2 Si(OH).sub.2, R being a monovalent hydrocarbon group, e.g. methyl or phenyl, in an organic solvent followed by baking of the coated substrate to convert the coating layer into a cured resin film.
