  • Patent number: 7796741
    Abstract: The invention provides a call connection control method which can use a conventional telephone as-is and performing linking with a low possibility of mistaking telephones, and a call connection control unit for implementing the method. Upon receiving an outgoing call request from an outgoing-call side personal computer (PC), a call connection control unit retrieves an outgoing-call side IP-telephone linked to the PC, and transmits an incoming call request to the IP-telephone. Upon receiving the incoming call request, the IP-telephone rings. When the caller places the IP-telephone that rings in a starting (off-hook) state, the call connection control unit sends a ring back tone to the IP-telephone and transmits an incoming call request to an incoming-call side IP-telephone. Upon receiving the incoming call request, the IP-telephone rings. When the recipient places the IP-telephone that rings in a starting state, the call connection control unit enables a call between the two IP-telephones.

  • Publication number: 20070161285
    Abstract: An electrically conductive contact holder comprises a supporting member including a low thermal expansion supporting frame with a coefficient of linear expansion lower than that of a to-be-contacted member and a high thermal expansion supporting frame with a coefficient of linear expansion higher than that of the to-be-contacted member, which are stacked one on another. With this structure, a coefficient of linear expansion of the entire supporting member can be approximated to that of the to-be-contacted member. Thus, it is possible to suppress the occurrence of displacement between electrically conductive contacts and external connecting terminals even under high temperature conditions.

  • Publication number: 20070121827
    Abstract: The invention provide a call connection control method of using a conventional telephone as-is and performing cooperation with low possibility of mistaking the telephone and a call connection control unit for implementing the method. On receiving an outgoing request from an outgoing-side Personal Computer, a call connection control unit searches for an outgoing-side IP-Telephone which is cooperated, and transmits an incoming request to the IP-Telephone. On receiving the incoming request, the IP-Telephone sounds a ringing tone. If a caller puts the IP-Telephone having sounded the ringing tone in a Starting State, the call connection control unit sends out a Ring Back Tone to the IP-Telephone and transmits an incoming request to an incoming-side IP-Telephone. On receiving the incoming request, the IP-Telephone sounds a ringing tone.

  • Patent number: 5589770
    Abstract: A mechanical sensor, comprising a ferromagnetic layer having magnetostriction, a ferromagnetic layer having magneto-resistance effect, a magnetic field generating means which excites these ferromagnetic layers, and a substrate which supports all these elements integrally, can be attained, which is small, thin, highly sensitive, and is capable of integration, by detecting a change of magnetic flux density passing through the ferromagnetic layers resulting from a change of magnetic properties caused by stress as a change of resistance value arising from magneto-resistance effect. As a result, a small, thin, and highly sensitive mechanical sensor can be provided using stress magnetic effect. Furthermore, based on the anisotropy of detection sensitivity, intensity of the stress along a certain direction can be detected selectively.
