Title: Pb signal receiver for telephone system
Inventor: KOMODA YOSHIYUKI
IPC: H04Q3/70
Filed: 1987-08-26
Abstract: PURPOSE:To prevent erroneous control due to the outgoing of the PB signal from a terminal side by comparing PB data at the time of the starting of reception with PB data after the disconnecting of a switch means, and deciding whether the former PB data is transmitted from a terminal-side or a non- terminal side. CONSTITUTION:If a PB signal in '0' is transmitted from a telephone set 3, it is received by a PB receiver 4, and PB signal data is outputted from the receiver 4. When the data is inputted from the receiver 4, an arithmetic and control circuit 5 stores the data, opens a relay contact ro during a constant hour, and disconnects the receiver 4 from a trunk L. If PB signals are consecutively received by the receiver 4, the circuit 5 compares them with the preceding PB signal data, an controls to hold if the coincide with each other. On the other hand, if a PB signal is inputted from the L-side of the trunk and the contact ro is opened, since the output from the receiver 4 ceases to be, the PB signal data first taken in by the circuit 5 and the data taken in after the opening of the contacting point ro differ from each other. Because of this dissidence, the circuit 5 judges the PB signal to be from the L-side of the trunk, hence a command corresponding to the PB signal is not executed.

Title: Josephson circuit
Inventor: KAWAKAMI GOUJI
IPC: H03K3/38
Filed: 1982-12-04
Abstract: PURPOSE:To realize DC drive and to attain stable operation even at the input of an error signal by connecting a hysteresis Josephson element in parallel with a non-hysteresis Josephson element. CONSTITUTION:When no input signal current Ic is applied, the hysteresis Josephson element 2 and the non-hysteresis Josephson element 10 are brought to superconduction. Thus, a bias current IB flows to the Josephson element 2 and does not flow to the Josephson element 10. When the current Ic is applied, the Josephson element 2 is brought into the voltage state and currents Ie, Ir flow. When the current Ir increases, the Josephson element 10 is brought into the voltage state and is stable at a stable point. When the current Ic is lost, the Josephson element 10 is restored to the superconduction state, and also the Josephson element 2 is returned to the superconduction state. This circuit is operated by so- called ''non-latch''.

Filed: 1997-08-07
Abstract: PROBLEM TO BE SOLVED: To have relevance between data, to visually and also efficiently change and eliminate a data structure in the middle of an operation and to construct a DB(database). SOLUTION: A data structure which is associated by attributes among classes which have the consistency of attributes is produced and is stored in a main DB 1. A work DB generating means 3 copies a data structure having relevance from the DB 1 to a work DB 4 at the time of changing the data structure. Here, when the class and attribute of the data structure is changed, a retrieving means 8 retrieves data that has relevance to changed class and attribute data from a work DB, and a matching means 9 checks the consistence between the retrieval result and the class of the data structure and the changed result of the attribute. As a result of consistency check, when the necessity to change the class and attribute of the data structure occurs from the relevance among classes, a changing means 10 performs change processing and registers it on the DB 1.
