IPC: H01B5/02
Filed: 1978-07-07
Abstract: PURPOSE: To make airtight sealing in glass sealing easy by coating the surface of an Fe-Ni oxide layer with a borax layer.  
     CONSTITUTION: A 6.6mm diameter oxygenless copper bar is inserted into a 50%Ni- Fe alloy tube of 20mm outside diameter and 6mm wall thickness, cold press welding and hot drawing are applied, cold drawing and intermediate annealing are repeated and they are formed into a composite wire of 1mm diameter. The composite wire is heated on a gas burner in the air and an Fe-Ni oxide layer of about 2μ is formed on the surface, then the wire is passed in borax solution and is heated again on a gas burner to enamel borax on the oxide layer on the surface of the composite wire. By so constructing, the outer surface is covered with the glassy borax layer, so the surface can be wetted with sealing glass very easily and under the borax layer, the Fe-Ni layer easily adaptable with glass is prepared previously, therefore, the airtightness between the composite wire and the sealing glass is improved. Further, sealing time is shortened and the over oxidation on the grain boundaries of the composite wire material can be avoided.

Title: Signal system for in-communication service
Inventor: KAIYAMA AKIRA
IPC: H04M3/42
Filed: 1982-05-17
Abstract: PURPOSE:To allow even a subscriber who has an in-communication service permitted terminal and an unpermitted terminal together on the same subscriber line to be offered service in communication, by transmitting a terminal indication signal which uses an out-band signal exerting no influence upon communication information from an exchange to the terminal, prior to the transmission of a display signal during the communication. CONSTITUTION:A DC intermittent pulse which is the out-band signal is used. A contact ts is closed by the indication TS of the transmission of a pulsating terminal indiction signal from the exchange body EX, and a relay A for indication signal transmission operates for a specific time. Consequently, while a terminal monitor relay B is held, the intemittent pulse signal is transmitted as a terminal indication signal to a terminal. The terminal side 2 receives the terminal indication signal and a relay C for monitoring the terminal indication signal which is held during communication is broken instantaneously. Consequently, a contact c1 for driving the relay of a terminal indication signal receiving display is reset to drive the relay D for driving said display and then a contact dg for driving the relay for said receiving display to power on the display E, displaying the reception of the terminal indication signal to the subscriber.

IPC: G01H1/00
Filed: 1979-06-29
Abstract: PURPOSE: To widen the frequency band width of a vibration sensor using a piezoelectric element by determining mu-factors A(ZR) and A(ZA) based on the output voltages VR and VA and the output impedances ZR and ZA of the resonance freqeuncy and anti-resonace frequency so as to satisfy VR.A(ZR)≈VA.A(ZA).  
     CONSTITUTION: The output of a vibration sensor 11 using a piezoelectric element is amplified together with R 1  and R 2  in an operational amplifier 13 constituting an inverted amplifier to output a voltage V 3 . In the equivalent circuit, V 2  is an equivalent supply voltage of the vibration sensor 11, and Z is its output impedance. The relation between the output impedances of resonance frequency fR and antiresonance frequency fA of the vibration sensor 11 is almost VR/ZR≈VA/ZA. The mu- factor of said circuit is A(Z)=R 2 /(R 1 +Z). Therefore, inversely amplifying voltages VR and VA by using ZR and ZA permits to uniform output voltages between fR and fA and to widen the frequency band width, so that a high sensibility can be obtained regardless of a frequency change.
