摘要： PROBLEM TO BE SOLVED: To understand level of an user using an answering terminal in real time, by communicating questions from a questioner (a teacher) with answers from the user using the answering terminal (a respondent or a student) using a one-to-one bidirectional wireless communication system. SOLUTION: When a questioner inputs data by using a keyboard or others, its signal is transmitted from a computer 400 to an answering/receiving terminal 300, and then RF(Radio Frequency) commands are transmitted from the answering/receiving terminal 300 to a distributing repeater 200. The distributing repeater 200 receives the radio-frequency commands and then transmits IR (Infrared Ray) data demanding commands added by terminal ID data to all of answering terminals 100. A user who uses the terminal overlays on the RF own data such as terminal ID, terminal user's ID, or answers from the answering terminal 100 and transmits them back to the answering/receiving terminal 300.

摘要： PROBLEM TO BE SOLVED: To precisely recognize the position of the holder of a data carrier by registering the position of the data carrier in a specific area in the base station covering the area and informing the movement tracing information of the holder in the area to the base station from the data carrier. SOLUTION: A system 500 is constituted of a data carrier 100, a base station 200, a host computer 300, etc. The data carrier 100 is mounted with a position detecting circuit using a high-frequency transmission circuit, a reception circuit, and an acceleration sensor. The base station 200 registers the ID number of a data carrier 100 entering its territory 400 and informs the host computer 300 of the ID number. The base station 200 also transmits a data request command in its territory 400 and the data carrier 100 having the coincident ID sends its own positional coordinates to the base station 200 in response to the command. Since the position of the data carrier 100 is registered and the movement tracing information of the holder of the data carrier is informed to the base station 200 through wireless communication in the above-mentioned way, the position of the holder of the data carrier can be recognized precisely.

摘要： PURPOSE: To realize the personal telephone service with an IC card or a telephone set having a simple structure by incorporating an antenna element for personal authentication, whose communication area is limited only to one person who hooks off the telephone, in the receiver, independent of an antenna element for position registration. CONSTITUTION: When the person who has a remote control type radio IC card 10 where personal ID information is recorded sits at the desk where a telephone set body 1 for personal number service is installed, information is sent from the card 10 to an antenna element 2 for position registration of the body 1 by radio, and the personal number service system performs personal position registration. Next, when call information to the person sitting at the desk is received by an exchange 9, call information is transmitted to the card 10 from the antenna element 2 of the body 1, and information of the call is transmitted to the specific person through an output device like a sounder. The person who receives call information is connected to the body 1; and when a receiver 6 is hooked off, it is reported to the system by the communication between the antenna for person authentication installed in the receiver 6 and the card 10 that the person who receives the call is valid. This system is connected to the body 1 by a line, and personal speech is possible.

摘要： PURPOSE:To provide the antenna which is miniaturized, provided with wide band performance and high reliability reducing connection. CONSTITUTION:On one substrate 4, a meandering radiator 1 and a capacitor 2 for matching circuit are simultaneously constituted so as to integrate these radiator 1 and matching circuit 2. Thus, the antenna provided with a much wider band can be provided from the characteristics of the matching circuit in a certain area smaller than a lambda/4 matching circuit composed of parallel lines and further when a superconducting thin film is used, the almost same performance as a superconducting antenna composed of a bulk material can be provided. Therefore, limit for designing the meandering radiator can be reduced.

摘要： PURPOSE:To flatten the surface of an oxide superconducting thin film and produce a reproducible and reliable thin film by etching the surface of an oxide superconducting thin film which is accumulated on a substrate and heat processed by an ion beam. CONSTITUTION:An ion beam 2 from an ion gun 1, for example, an argon ion beam, is accumulated by sputtering on a substrate 3, and a superconducting thin film 4 which is heat processed in oxygen atmosphere is irradiated by the beam 2. The substrate 3 incorporates an heater 5A and is supported by a turnable substrate holder 5. At such time, the parameters are etching gas, gas pressure, substrate temperature, the angle between an etching ion and the substrate (theta), an acceleration voltage, ion current density, etc. A thin film of Bi2Sr2 Ca2Cu3Ox is accumulated on the MgO (100) substrate for 2000Angstrom in thickness by sputtering and the substrate is heat processed in the oxygen atmosphere for an hour. Such surface treatment removes an impurity layer on the surface of the oxide superconducting thin film, improves the surface and superconductivity.

摘要： PURPOSE:To aim at improvement of controllability of device performance by controlling the dispersion of performance due to forming deterioration, and at the same time, to aim at higher performance by applying etching an oxide superconductor with ion for etching, while irradiating oxygen plasma, after completing the photo-lithography process. CONSTITUTION:A resist mask is formed on a thin film composed of BiSrCaCuO with the same conventional photo-lithography. A sampler 1 is put on the lower part of a vacuum chamber 4 to which an ion is irradiated from a gun 2 and oxygen plasma is irradiated from an oxygen-plasma generator 3. As a result, a pattern of BiSrCaCuO is formed. A complete non-superconduction as shown in curve b can be restrained, and the deterioration of Tc at the pattern width of 2mum, as shown in curve C, is limit only to 65K. On the other hand, it is easily made possible to provide oxygen to be derived by etching gas. If conditions are optimized, a very minute pattern without any deterioration of superconductive characteristics can be ideally formed.
