Title: Polytetrafluoroethylene microballoon and its production
Inventor: SUNAHARA KAZUO
IPC: B01J13/02
Filed: 1994-02-02
Abstract: PURPOSE:To easily produce microballoons with a low density and a good flowability by introducing minute liq. droplets of polytetrafluoroethylene or its precursor into a specified high-temp. atmosphere. CONSTITUTION:A soln. or dispersion contg. polytetrafluoroethylene or its precursor dissolved or dispersed in a liq. medium is converted into minute liq. droplets and introduced into an atmosphere with a temp. high enough to vaporize the medium quickly and to sinter or melt polytetrafluoroethylene. As the medium vaporizes quickly at the surface of the droplets. polytetrafluoroethylene or its precursor dissolved or dispersed in the droplets precipitates along the interfaces of the droplets to form spheres. While the remaining medium vaporizes and dissipates, polytetrafluoroethylene moves in the centrifugal direction, hollowing the droplet insides, and forming microballoons. Pref. the microballoons have an average particle diameter of 0.1-300mum, a bulk density of 0.001-1.5g/cm<3>, and a true density of 0.01-2.0g/cm<3>.

Title: Ignition coil for internal-combustion engine
Inventor: YAMADA HIROSHI
IPC: H01F38/12
Filed: 1985-01-25
Abstract: PURPOSE:To obtain an ignition coil for an internal-combustion engine in which the secondary coil is divisionally wound and deviation of the ignition time can be prevented, by adjusting the ratio between the number of turns of the secondary coil and the number of turns of the primary coil to a proper value. CONSTITUTION:If the turns ratio is set to 50, the waveform of the no-load secondary induced voltage is as shown in Fig. A with the fundamental wave component Vf appearing at the time of rising. Figs. B and C illustrate the waveform of the no-load secondary induced voltage for the turns ratio of 60 and 70, respectively. As apparent from these waveforms, the larger the turns ratio becomes, more remarkably appears the fundamental wave component at the rise of the no-load secondary induced voltage, so that the rise of the no-load secondary induced voltage becomes stable. Thus, in an ignition coil including a secondary coil of the divisional winding type, the larger the turns ratio is set, the less the deviation of the ignition time is made. If the turns ratio is set to 50 or larger, the deviation width of the ignition time can be limited to the range providing no hindrance for practical use.

Abstract: PURPOSE:To judge whether a cable can be laid down or not additionally inside a laid old cable duct beforehand by analyzing a received waveform varying with the movement of an oscillator to diagnose the internal condition of the duct. CONSTITUTION:A sound is generated from an oscillator 2-1 by air flow inside a cable duct 3, and a received waveform which varies with the movement of the oscillator 2-1 is analyzed to diagnose the internal condition of the duct. Namely, because the velocity of the air flow varies if sediment, etc., enters the duct 3 or its cross-section varies due to pressure, the level and frequency of the sound are varies. Also, if surrounding conditions are varied by entry of sediment, etc., or cross-section of the duct is varied, the echo and resonance conditions of the emitted sound are varied, and the received tone quality is varied. Thus the internal condition of the duct 3 can be judged by analyzing the variation of the received wave length.
