. A doping CaO-B2O3-SiO2 system low temperature co-fired ceramics (LTCC) was prepared with a mixture of high temperature melting glass and sol-gel glass for different ratio. The effects of sol-gel glass content on the microstructure, crystalline phases, sintering properties and dielectric properties of CaO-B2O3-SiO2 system were investigated at 850°C. The results show that the samples with sol-gel glass doping had little change in phase composition, but contained more calcium silicates, and less calcium borate. As the amount of sol-gel glass increased, the shrinkage improved, the sintered density slightly decreased, the dielectric constant (εr) reduced, and the dielectric loss (tgδ) decreased. When the amount of sol-gel glass was 14.5wt%, εr and tgδ of the doping sample were 5.80, 4.6×10-5 (at 1 MHz), respectively. Moreover, the doping system had a good matching ability with gold slurry and Au-Pt-Pd slurry.

The Universe

Our present theories of particle physics and cosmology, taken together, suggest that very early in its history, the universe underwent a series of phase transitions, at which topological defects, similar to those formed in some condensed matter transitions, may have been created. Such defects, in particular cosmic strings, may survive long enough to have important observable effects in the universe today. Predicting these effects requires us to estimate the initial defect density and the way that defects subsequently evolve. Very similar problems arise in condensed matter systems, and recently it has been possible to test some of our ideas about the formation of defects using experiments with liquid helium-3 (in collaboration with the Low Temperature Laboratory in Helsinki). I shall review the present status of this theory.

This paper proposes a new filling material, fiber-reinforced ice (FRI), for tube bending. In tube bending, lead and low temperature melting alloys have conventionally been utilized as the filling medium to prevent defects and to alleviate flattening of the tube’s cross section. However, these alloys are usually harmful to the environment (e.g., Pb, Bi-Pb-Sn-In, or Pb-Cd system alloys) or are expensive (e.g., In-Sn system alloys). In this study, the author utilized ice reinforced with the fiber of wastepaper for 3-point bending of JIS G 3452 SGP 32A steel tubes. Compression tests were conducted to analyze whether these tubes have crushing strength comparable to that of conventional fillings and sufficient ductility in low-speed deformation. The filling medium with more fiber effectively yielded less flattening.
