摘要： A voltage value of an impulse voltage repetitively applied on a test-piece coil is increased in accordance with time elapse. A terminal voltage applied on both ends of the test-piece coil is monitored to detect an electric breakdown of the test-piece coil. Upon detecting such a breakdown, application of the impulse voltage is immediately stopped to prevent the test-piece coil from being unnecessarily damaged. Meanwhile, a voltage value of the impulse voltage is measured quantitatively at the time the electric breakdown is detected and the measured data is stored in a memory, so that the memorized data can be used later as a breakdown voltage value.

摘要： A high-performance Nb3Al extra-fine multifilamentary superconducting wire is produced simply and inexpensively through the improvement of critical values, Tc, Hc2 and Jc, without the addition of third elements such as Ge, Si and Cu. A first rapid heating and quenching treatment is applied to an Nb/Al composite wire having an atomic ratio of Al to Nb from 1:2.5 to 1:3.5 and having an extra-fine multifilamentary structure to form a BCC alloy phase comprising Nb with Al supersaturatedly dissolved therein wherein the treatment comprises heating the composite wire up to a temperature not lower than 1900° C. within two seconds and then introducing it into a molten metal at a temperature not higher than 400° C. to rapidly quench it. The wire is subjected to a second rapid heating and quenching treatment to form an A15-Nb3Al compound having a low degree of crystalline order but having an approximately stoichiometric composition wherein the second treatment comprises heating the wire up to a temperature not lower than 1500° C. within two seconds and then introducing it into a molten metal at a temperature not higher than 400° C. Then, an additional heat treatment is conducted to improve the degree of crystalline order of the Al5-Nb3Al compound having an approximately stoichiometric composition.

摘要： According to a portable electronic apparatus processing system of this invention, an IC card sends, to an IC card reader/writer, first timer data included in an answer to reset signal and defining a time after it sends the answer to reset signal to the IC card reader/writer until an instruction is received from the IC card reader/writer. The IC card receives a first instruction from the IC card reader/writer and executes corresponding processing. The IC card also sends second timer data included in the answer to reset signal and defining a time after the processed result is sent to the card reader/writer until the next instruction is received from the card reader/writer. The card reader/writer sets the first timer data in a timer, and sets the second timer data in a memory. The card reader/writer sends the first instruction to the IC card in response to a time out signal from the timer. When the card reader/writer receives the processed result from the IC card, it reads out the second timer data from the memory, and sets the readout data in the timer. Then, the reader/writer sends the next instruction to the IC card in response to the time out signal from the timer.

摘要： In an IC card (electronic smart card) which can record or register a plurality of personal identification numbers (PINs), an externally entered personal identification number is collated with the personal identification numbers registered in the card, and when a coincidence occurs between the entered PIN and one of the registered PINs, a flag is set to indicate coincidence therebetween. At least two of the registered PINs share the same flag information. Each noncoincidence between an entered PIN and a registered PINs is counted. Response data indicating the unusability of the PIN is issued when the number of noncoincidences exceeds a predetermined value, while when the number of noncoincidences is below the predetermined value, response data indicating the PIN noncoincidence is issued. In counting the number of noncoincidences, the first count is made by a nonvolatile memory so that it may not be erased when a power supply is turned off and the subsequent counts are made by a nonvolatile memory.

摘要： According to the portable electronic apparatus of the invention, when a data string is to be written in a data memory, information indicating whether the data string is valid or not is appended to the data string, and the data string is stored. When a read instruction is supplied from a portable electronic apparatus handling system, a CPU connected to the data memory appends the information, indicating validity or invalidity of the data string, to the start of the readout data string, and supplies the data string to the portable electronic apparatus handling system. When the data string supplied from the portable electronic apparatus handling system is to be written in the data memory, the CPU appends the information indicating invalidity to the data string and writes the data string, thereby updating the information indicating invalidity to information indicating validity after the completion of the data string writing.
