Title: Electrical insulating gasket
Inventor: YOSHIMOTO SENTARO
IPC: F16L23/02
Filed: 1995-01-31
Abstract: PURPOSE: To provide a high temperature serving electrical insulating gasket that combines both excellent sealing and electrical insulating properties under the condition of high temperature and pressure. CONSTITUTION: A metal outer ring 21 is fitted in the outer circumferential side of a spiral-wound gasket body 20, and a section square joint-sheet ring connecting member 22 is fitted in the inner circumferential surface, using them as a core member, and two ring outer cover plates 24 made of filler-mixed PTFE each are superposed on the contact surface of this center member to a piping flange 23 in a sandwiching manner, then these outer cover plates 24 are unified to the connecting member 22 after bonding with a binder 25. Since this filler-mixed PTFE ring outer over plate is excellent in both heat and flow resistant properties in particular, it synergistically acts together with a characteristic of the spiral-wound gasket body or the core member, so excellent sealability is brought into full play under the condition of high temperature and pressure.  Moreover, since the outer cover plate covers the metal outer ring, there is no problem as to the electrical insulating property.

Title: Coil slot of rotary machine
Inventor: SATOU TADAYUKI
IPC: H02K3/487
Filed: 1978-03-24
Abstract: PURPOSE: To eliminate the need for a gap in a coil by inserting a tube in which gas is enclosed and sealed at the rear of a slot wedge, expanding this tube at resin thermosetting, and applying pushing force to the coil.  
     CONSTITUTION: The tube 6 in which gas 6b is enclosed is inserted at the rear of the slot 3. Using the heat at the time when the resin filled in the slot 5 is thermoset, the gas 6b in the tube 6 expands and pushing force is applied to the coil 2. In this case, the tube 6 has the heating fusing section 7 which is intervaled properly. Even if the section is cut in any position according to the length of slot 5, 50% or more of its length must form the enclosed section of the gas 6b. This eliminates the need for the gap in the coil 2 and improves both heat transfer and mechanical strength.

Abstract: PURPOSE:To prevent an unnecessary ringing of a bell of a telephone set when starting and ending data communication by varying slowly the voltage of a line at the time of a polarity inversion and its resetting. CONSTITUTION:When starting data communication, a channel 60 is formed, and as a polarity inversion command signal A to a control part 80 is turned on, a signal A becomes on, signal groups QA-QN are sent out successively from a timing circuit 20, and as a result, a timing circuit 30 sends out the voltage VO of a DC power source 10, as a step-like waveform in the positive direction. Subsubsequently, when the signal groups QA-QN become all on, a signal D rises, the output B becomes off, the signal groups QA-QN fall successively, and the step-like waveform voltage in the negative direction is sent out of the circuit 30. As soon as the signal D rises, a switching circuit 50 is operated, the polarity inversion of the waveform voltage in the negative direction is executed, and the step-like waveform voltage in the positive direction is supplied to a subscriber's telephone circuit 70. On the other hand, when ending the data communication, the signal A becomes off, and in the same way as the case of the polarity inversion, the step-like waveform voltage in the negative direction is supplied to the circuit 70.
