摘要:
A functional relation between components which can be extracted from an already existing program in advance is automatically extracted by a computer, or such a functional relation which cannot be extracted is defined by a developer, so that the preparation of a program by combining the components is assisted. A dictionary registration unit reads a source code file, analyzes, extracts a component definition, and extracts from the component definition information a counterpart component name, interface name, and interface definition, and registers component name, counterpart component name, interface information of the interface name, and interface definition body in a dictionary. Furthermore, when there is no source codes, the developer inputs the interface information from an input-output device, and registers in the dictionary. A program editing processing unit, on the basis of a user's indication, retrieves and displays a list of interfaces between components, and also extracts the interface definition from the dictionary, thereby to assist the user in preparing a program by combining the components.

A photoelectron emitting member and method of electrically charging fine particles with photoelectrons, wherein the member includes a matrix that is at least composed of a material capable of transmitting ultraviolet rays and a material that is provided on the surface of the matrix or in its neighborhood and which emits photoelectrons upon irradiation with ultraviolet rays or sunlight. The member emitting photoelectrons upon irradiation with ultraviolet rays or sunlight is disposed in an electric field from the side opposite to the irradiated side. The member permits efficient utilization of the energy of ultraviolet rays. When sunlight is applied to the member to have it emit photoelectrons, particles can be electrically charged with energy costs being reduced to substantially zero.

An object of the present invention is to provide a particle-shaped water absorbing agent having a remarkably improved surface color and excellent water-absorbing properties (better water absorption capacity, and lower water soluble content and residual monomer content) at the same time. In order to attain the object, a particle-shaped water absorbing agent according to the present invention is a particle-shaped water absorbing agent whose main component is a polyacrylic acid and/or a salt thereof, the particle-shaped water absorbing agent having a surface color of Hunter b value in a range of −5 to 10, and having a cross-linking absorption property index (CPI) in a range of 1 to 100, the CPI defined by the following two equations: GEX=(GVs+17)/Ln (water soluble content); Equation 1: CPI=(GEX/residual monomer content)×100 Equation 3: where GVs is gel volume in saline, Ln (water soluble content) is a logarithm natural of water soluble content.

摘要:
A communication terminal, in case that transmission/reception of a frame is carried out between a management terminal and another communication terminal, reads out its frame content, and on the basis of a content of the frame which was readout, sets up power off time for turning off power of the communication terminal, and turns off power of the communication terminal, during a period of the power off time. By this means, depending on a content of a frame which is transmitted/received between another communication terminal and the management terminal, power off time of the communication terminal is calculated, and therefore, it is possible to turn off power of the communication terminal during such a period that transmission/reception is not carried out to/from the management terminal, and it is possible to suppress power consumption of the communication terminal.

摘要:
Chilled coolant is prepared by liquid coolant utilizing the latent heat generated by a gasification of liquefied propylene, for example, and this chilled coolant is used in heat exchangers which are used in a process for production of acrylic acid or acrolein. This method allows effective utilization of the latent heat which used to be discarded and permits a reduction of energy consumption of cooling required separately in the step for production. By recovering the chilled coolant with the liquid coolant, it makes possible to stabilize the gasification of propylene, etc. and consequently stabilize the production of acrylic acid. This invention consists of providing the method for the production of acrylic acid, etc. and the apparatus which make effective use of the latent heat generated in the steps of production.
