Title: Line holding system for radio telephone set
Inventor: KATAOKA NAOHITO
IPC: H04W4/16
Filed: 1991-02-20
Abstract: PURPOSE:To grasp the communication stage of the other subscriber by holding a subscriber line, and informing its situation by voice information, in the case electric field strength becomes below a set value determined arbitrarily in advance, and a communication cannot be executed enough. CONSTITUTION:An electric field strength detecting circuit 4 of a base station side measures electric field strength from a moving station, and sends out an alarm signal, when it becomes below a set value. When this state elapses exceeding a set time, a line holding instruction of a subscriber telephone line 12 is executed to a holding control circuit 6, and a holding signal is sent out to the moving station from a holding signal sending-out circuit 5. The circuit 6 controls a holding circuit 8, holds a subscriber's circuit, and also, actuates a voice information sending-out circuit 11, and informs voice information of a fact of holding the circuit to the other subscriber who is connected. In such a way, the other subscriber can grasp a communication state even in the case the communication cannot be executed enough.

Title: Method for safely executing communication in communication system
Inventor: HERLIN HARRY
IPC: G06Q20/36
Filed: 1998-02-06
Abstract: PROBLEM TO BE SOLVED: To realize security communication by verifying the identity of a user with a public key method and using an inexpensive ciphering method as calculation. SOLUTION: Key matching and authentication processing procedures are started in a base station B1. Triplets (b1, Eb1 and Cb) are sent to a moving station M1 and M1 calculates f(b1 and Eb1) from received values b1 and Eb1. It is judged to be equal to E0(Cb) or not (S202-206). When Cb is verified to be true, a password key (k1) is selected, Eb1(k1) is generated and is sent to B1. B1 generates Db1(Eb1(k1)) and M1 ciphers the triplets (m1, Em1 and Cm1) of M1 by using k1 and sends them to B1. B1 decodes the ciphered triplets by using k1 and generates again the triplets (m1, Em1 and Cm1), calculates f(m1 and Em1) by using the values of m1 and Em1, which are received by the triplets from M1 and judges whether it is equal to E0(Cm1) or not (S210-222). When Cm1 is true, B1 selects a new ciphering key (k2) (S206).

IPC: C08F6/00
Filed: 1993-02-16
Abstract: PURPOSE:To enable the charge and discharge at a high current density, and to obtain a comp molding effective as the active material for polymer secondary battery having a high charge and discharge capacity by dipping negative ion, which is included in polypyrrole obtained by the electrolytic polymerizing method, in the polar organic solvent before/after changing the negative ion to smaller negative ion. CONSTITUTION:Polypyrrole is obtained by dipping an electrode substrate for polymerization in the solvent, in which support salt including negative ion and positive ion at a large ion size and pyrrole are dissolved evenly, and performing the electrolytic oxidation polymerization. The negative ion at a large ion size is surrounded by the polymer at the time of polymerizing polypyrrole, and the operation for exchanging the negative ion with a smaller negative ion is performed. When this polypyrrole negative ion is exchanged, polypyrrole is dipped in the organic solvent having a high affinity with the polypyrrole before or after the exchange. Movement of the small negative ion for diffusion is thereby facilitated to obtain a molding having a high charge and discharge capacity.

Inventor: MITANI TOKIYOSHI
IPC: H04M1/60
Filed: 1986-02-12
Abstract: PURPOSE:To stop a ring tone by using a ring tone detector discriminating whether or not the state is in the ring tone state and starting a variable frequency characteristic circuit by an output signal of the detector and using the variable frequency characteristic circuit to change the frequency characteristic of a channel. CONSTITUTION:A ring tone detector 13 detects a single frequency component, a prescribed signal level or over and a prescribed duration time or over so as to detect whether or not the signal of a talking channel is in the ring tone generating state. When a ring tone is generated, a start signal is outputted to start the variable frequency characteristic circuit 14, which outputs an input signal as it is when the talking channel is in the normal talking state and uses a start signal to turn on a field effect transistor thereby constituting a low pass filter and changing the frequency characteristic of the talking channel. That is, the variable frequency characteristic circuit 14 changes similarly the frequency characteristic as a low pass filter and lowers the gain of the ring tone frequency to stop the ring tone.
