IPC: G11B19/02
Filed: 1999-02-02
Abstract: PROBLEM TO BE SOLVED: To protect information from an emergency situation by detecting the emergency situation and transferring information of a portable type recording medium to another terminal device with use of the detected result. SOLUTION: A detecting circuit 4 detects an emergency situation such as when a theft or a robbery takes place, when a power source is cut off or the like. For example, the detecting circuit is a sensor circuit for sensing shocks or vibrations, a circuit for detecting that a terminal apparatus 1 is raised on purpose, or a circuit for detecting that the power source of the terminal apparatus is cut off. A signal detected at the detecting circuit 4 is input to a control circuit 5. Information of a portable type recording medium 2 is read out by a write/read circuit 3 and transferred concurrently to another terminal apparatus 7 via a communication driver circuit 6, so that the information is backed up for a case of emergency. After this or simultaneously with this, information held by the portable type recording medium 2 is erased.  It is possible to prevent a third party from using the medium by locking the medium so that the information cannot be rewritten or taken outside.

IPC: H01F6/02
Filed: 1984-02-15
Abstract: PURPOSE:To obtain a device superior in energy recovery efficiency and having low cost and high reliability by using such non-linear resistive elements as varisters as resistive elements. CONSTITUTION:An energy recovery device 11 is composed by connecting a series circuit of a resistive element 7A (resistance value RDA) and a diode 8 for preventing shunt currents in parallel with a series circuit of a non-linear element 12 such as a varister (dynamic resistance value R12) and a resistive element 13 for adjustment (resistance R13, R13<R12). The resistance value RE of the energy recovery device 11 seen from the side of the terminals of a superconductive magnet 3 is equal to a resistance value R which provides the most superior recovery efficiency at the initial period of quenching. Also, if resistance values of each resistive element has been set in such a manner that RDA>RD holds, the resistance value RE gradually increases toward the resistance value RDA by increase in the dynamic resistance value R12 of the non-linear resistive element 12 brought about by reduction in the voltage across the magnet, allowing a great amount of energy to be recovered.

Abstract: PROBLEM TO BE SOLVED: To eliminate phase noise and to discriminate modulation signals by heterodyne-receiving modulated waves, obtaining difference frequency signals from beat signals due to carrier frequency components and modulation side band wave components and sending them to a signal receiver. SOLUTION: A receiver A sends out carrier waves from a laser light source 101 through an isolator 102, an optical multiplexing/branching circuit 103 and an optical transmission line 108 to respective transmitters 1 and 2. In the meantime, the respective transmitters 1 and 2 modulate the carrier waves in a modulator 111 and outputs the modulated waves through the optical multiplexing/ branching circuit 109 and the isolator 110. The modulated waves reach the receiver A and are inputted through the optical multiplexing/branching circuit 103 to a heterodyne receiver 105. In this case, heterodyne reception is performed by using a carrier wave frequency from a local light source 104 and the beat signals due to the carrier frequency components and the modulation side band wave components are obtained. A difference frequency signal detection circuit 106 obtains the difference frequency signals from the beat signals and sends them to the signal receiver 107. Thus, the phase noise is eliminated and the modulation signals are discriminated.
