  • Publication number: 20020046585
    Abstract: A waste of asbestos-containing inorganic building materials is reacted and burnt at a temperature in a range of 600° C. to 1,500° C. to obtain a recycled silicic acid type fertilizer with decomposed asbestos. Thus, the asbestos contained in the inorganic building material waste, which is said to be harmful to the health, is decomposed and recycled as the silicic acid type fertilizer.

  • Patent number: 5678369
    Abstract: Disclosed is a refractory/heat insulating panel used in buildings and structures which must have a refractory performance. In the refractory/heat insulating panel (801), the mechanical strength and the fireproofing performance at the joint portions, which are weak portions in the panel, are increased by integrally forming inorganic boards (831) in the male and female joint portions (832, 836), filling a light-weight aggregate in the core material located at the male and female joint portions at a high density, or making the density of the core material at the joint portions higher than that at the center of the panel.

  • Patent number: 5620517
    Abstract: As a device used to paint a pattern such as a band, stripe or streak on the surface of an elongate and thin base material continuously supplied, a painting device is composed of at least a painting groove provided across the moving direction of the base material continuously supplied and having an opening formed along its both ends with a width wider than the width of the above-described base material in a manner not to be closed by the base material, a primary pipe communicated with the painted groove and a secondary pipe linked with the primary pipe, so that different kinds of paints are filled into the painting groove through the primary and secondary pipes to paint a pattern such as a band, stripe or streak over the whole surface of the base material in motion.

  • Patent number: 5580637
    Abstract: A sandwich panel which is formed by sandwiching a core member of synthetic resin foam (plastic foam) between a front surface member and a back surface member into an unified body, is provided with plural gas-permeable members in the core member or/and at the boundary between the core member and the front and/or back surface member of the sandwich panel, whereby internal gas produced in the core member is discharged through the gas-permeable members to the outside of the sandwich panel.

  • Patent number: 4764102
    Abstract: A continuous elongate ceramic article manufacturing system capable of continuously manufacturing elongate ceramic articles having a predetermined length by continuously extruding a clay material containing clays as the principal components in a hollow or solid continuous strip, drying the continuous strip in a short time, firing the dried continuous strip, and cutting the fired continuous strip in the predetermined length. The system comprises a continuous arrangement of an extruder, a drying machine, a cutter, and a firing furnace arranged in that order, or a continuous arrangement of an extruder, a drying machine, a firing furnace, and a cutter arranged in that order.

  • Patent number: 4407179
    Abstract: Process and apparatus for cutting an elongate complex structure composed of materials having different properties, e.g. a liner and a core which are relatively soft and flexible and susceptible to rupture or crushing and a facing of hard material such as a metal plate. The facing may have an upwardly turned portion, flange portion and groove portion at each side thereof. A carriage and a base frame are movable in the direction of the travel of the complex structure and in the direction perpendicular thereto, respectively. Various types of cutters are mounted on the carriage. The complex structure is instantaneously cut in the direction of the width thereof while it is travelling at a high speed. The cut composite structure has smooth and fine cut edges, and is useful for e.g. a siding of a building.
