摘要： PROBLEM TO BE SOLVED: To make it possible to share the same service information between users belonging to the same group and to enable a chat with other users in the same group, in a system in which plural clients are connected with the server and an offer of service is received by them. SOLUTION: Common use of service in the same group is recognized by referring to a user management file 21 by a server 20. In addition, a message received from a client 10 is repeated to the other client 10 in the group by the server 20. A service request received from the client 10 is judged, and when the service request is a service information to be shared, the same service information is transmitted to all the users in the group by a service request reception 4. When the service request is the service to be individually offered, the service information is transmitted only to the client who requests the service by a method to switch a utilization mode of the client to single use, etc.

摘要： PURPOSE: To provide a method of manufacturing a low-resistance high permeability transparent conductive film. CONSTITUTION: A transparent conductive film is irradiated with a particle beam consisting of at least one element among He, Ne, Ar, Kr, and Xe during manufacture or after manufacture of a tin-added indium oxide (ITO) film, an indium oxide film, or a tin oxide film. The energy of a particle beam is decided, according to film growth temperature or crystallization temperature. In case that the difference to the crystallization temperature is large, the energy of a particle beam is enlarged. In case that the difference to the crystallization temperature is small, the energy of a particle beam is made small.

摘要： PURPOSE:To estimate the demand of a market from sales information gathered in the small number of regional markets. CONSTITUTION:The sales characteristic information of the regional markets constituting the entire market is inputted to a computer 201 by using an input device 202 (a step 101), the regional markets are grouped into the ones provided with similar features by the sales characteristic information (the step 102) and a representative regional market representing a group is selected (the step 103). The sales information in the representative regional market is inputted to the computer 201 by using the input device 202 (the step 104), the sales information of the regional markets other than the representative regional market is estimated from the sales information in the representative regional market (the step 105) and the demand of the entire market is estimated based on the sales information of all the regional markets (the step 106). Thus, the demand of the entire market including a lot of the regional markets is highly accurately estimated at a low cost.

摘要： PURPOSE:To obtain a spin interaction element having high sensitivity by using an oxide magnetic material as a magnetic material and providing an intermediate layer between magnetic layers. CONSTITUTION:A magnetic material 12 and an intermediate layer 13 are formed on a base body 11 so as to obtain a laminated film of three-layer structure. As an intermediate layer 13, YBa2Cu3Oy (y is 6.0-7.0), for example, is used and as a magnetic material 12, an oxide magnetic material such as La0.7Ca0.15 Sr0.15MnO2 (Z is 2.7-3.3) is used. As a base body 11, the one obtained by grinding a single crystal into a mirror surface is used. For example, the film thickness of each layer of the laminated film of the three-layer structure is so formed that the intermediate layer 13 may be 200mm and the magnetic material layer 12 may be 200mm on the base body 11 of SrTiO3 (100) of 10X10X0.5. As a result, a magnetism detecting element having high sensitivity and fast responsibility is obtained.
