Title: Refractory and fire-resistive foamable caulking
Inventor: OOTA NOBURU
IPC: C08K7/16
Filed: 1985-02-04
Abstract: PURPOSE:To obtain the titled caulking capable of imparting an improved refractory and fire resistive characteristics to a building, by mixing a rubber or synthetic resin with a metal salt of boric or silicic acid and an uncalcined perlite powder, vermiculite powder or Shirasu powder. CONSTITUTION:A base material of a rubber or synthetic resin or a mixture of two or more of them is mixed with a metal salt of boric or silicic acid and, further, with an uncalcined perlite powder, vermiculite powder or Shirasu powder and optionally with an asbestos fiber, glass fiber, colorant, anti-aging agent, etc., to thereby obtain a desired caulking material. When exposed to a temperature of 120 deg.C or higher, the caulking material forms a ceramic foam over flames to shield oxygen to thereby prevent burning. When the temperature reaches 400 deg.C or higher, it expands to have a volume of about 20 times larger than that of the original state, thus imparting an increased thermal insulation properties. Further, when exposed to a flame having a temperature of 1,000 deg.C or higher, it exhibits refractory and fire-resistive characteristics, i.e. forms a firm, incombustible heat insulating barrier over the flame.

Abstract: PURPOSE:To provide an electronic watch, which has excellent electric characteristics and a low power consumption, by accomplishing the channel doping steps at least twice for a complementary MOS integrated circuit (or C-MOS). CONSTITUTION:A supply voltage is converted through a voltage converter 9 from  high VSSH to low VSSL and is fed to a transmitter 1 and a high frequency divider 6. Both the threshold voltage BTHN of an N channel MODFET constituting the region 10 of the C-MOS made operative at the low potential VSSL and the threshold voltage ¦ VTHP ¦ of a P channel MOSFET are made lower than those of the transistors constituting the other regions of the C-MOS. As a result, the channel doping step is added at least once to the P channel and N channel MOSFETs of preset region. Thus, it is possible to produce an integrated circuit which has excellent electric characteristics and a low power consumption.
