摘要:
An optical recording medium includes a substrate, first information for modulating a phase of read light radiated on the substrate, and second information for modulating an amplitude of the read light radiated on the substrate. The first information and the second information are arranged in parallel to each other on the substrate in a predetermined arrangement direction. A method and apparatus for performing reproduction using this medium are also disclosed. The method includes the step of radiating read light on the optical recording medium in which the first information for modulating the phase of the read light and the second information for modulating the amplitude of the read light are recorded, the step of receiving light through the optical recording medium, the detection step of independently detecting phase modulation information and amplitude modulation information of the optical recording medium using the received light, and the step of reproducing the first information and the second information from the information in the detection step.

A waveguide type wavelength measuring apparatus is provided with a single mode channel type optical waveguide formed on a waveguide substrate, in which the light to be measured is inputted, a double mode waveguide connected to the single mode channel type optical waveguide, waveguide branches for branching the light output from the double mode waveguide, and photodetectors for detecting independently the light branched by the waveguide branches. The wavelength of the inputted light is measured on the basis of the output signals from the photodetectors. Hence it is possible to perform precise real-time measurement of the wavelength of the incident light with a compact and extremely miniaturized structure.

A content distribution system which assures reliability of content is provided. Permitted-user information corresponding to a user who is permitted to use content to be distributed is associated with the content. In the case where user specific information which specifies a user and the permitted-user information do not have a predetermined relation, a user terminal transmits the user specific information and the permitted-user information to a server. The server generates user-related information in which the received user specific information is set as a distribution destination and the permitted-user information is set as a distributor, generates new permitted-user information so as to have the predetermined relation with the user specific information, and provides the new permitted-user information to the user terminal. The user terminal which obtains the new permitted-user information changes the permitted-user information to the new permitted-user information.

Face-to-face information exchange and fostering of human relations implemented by communication through the virtual world are favorably supported. A user's personal information or other real-world information related to the user is taken one after another into a portable device with memory incorporated. Further, data is taken out of the device and matched with data from another user's device. Thus, information exchange and fostering of human relations are supported in the real world through the virtual world. For example, the present invention is used to provide places for intra-generational and intergenerational encounters or to build message boards for job hunting activities or looking for a match.

A communication apparatus is provided including a display unit, a storage unit capable of storing therein display condition information in which a display instruction for causing the display unit to perform display processing or a non-display instruction for not allowing the display unit to perform the display processing is set, and a short distance wireless communication control unit for controlling a connection establishment communication with a communication party by a communication system based on electric field coupling or magnetic field coupling and data communication with the communication party by the communication system. The short distance wireless communication control unit judges whether the non-display instruction is set in the display condition information stored in the storage unit, and does not make the data communication with the communication party when judging that the non-display instruction is set, the communication control unit.

The present invention provides a new supply source of enzymes useful for modification of phospholipids for example, and also provides a method for producing 2-acyl lysophospholipid, a method for producing monoacylglycerol, and a method for producing ceramide, as well as a new method for degumming fat and oil.A novel microorganism is provided, which belongs to Moritella species and is capable of producing enzymes provided with: phospholipase A1 activity; phospholipase C activity; lysophospholipase C activity; and sphingomyelinase activity. By use of those enzymes, the following processes may be effected: hydrolysis of phospholipids for production of 2-acyl lysophospholipid and diacylglycerol; hydrolysis of sphingomyeline for production of ceramide; and degumming of fat and oil.
摘要:
A high-temperature steam turbine plant is of the top turbine type and structured as follows. It comprises a boiler building including a vertical boiler on the top of which a VHT turbine is installed; and a turbine building installed on the ground as a base. The VHT turbine and a generator connected with it are installed on the top of the boiler. The material for the portion of the steam pipe between the boiler building and the turbine building which is exposed to highest steam pressure is austenite steel which contains 50 weight % or more of ferrite steel or Fe. The inlet temperature of the VHT turbine is 675° C. or more and its outlet temperature is 550° C. or more and 650° C. or less.
摘要:
A wireless communication system performs high-speed and low-speed transmission of information signals for short-distance communication and long-distance communication by using a short spread code and a long spread code, respectively. A wireless transmission unit includes an interface, a buffer, a spreading processor, an ultra wide band (UWB) wireless transmitter, a controller, a data memory, and an antenna. The controller detects the entry of information signal into the buffer, and then determines the transmission rate depending on the state of wireless linkage and indicates the determined transmission rate to the spreading processor.
