Patent JP-S58197028-A (JP)
Title: Pre-foaming of thermoplastic resin granule
Inventor: SENDA KENICHI
IPC: B29C67/00
Filed: 1982-05-13
Abstract: PURPOSE:To uniformly expand the granules of a thermoplastic resin preliminarily without causing hot-bonding of the granules by a method in which thermoplastic resin granules containing a volatile blowing agent are dispersed in water in a pressure-resistant container, pressurized and heated under specific conditions, and then discharged to a low-pressure free space from a discharge port leading to the inside of the container. CONSTITUTION:Thermoplastic resin granules 2 containing a volatile blowing agent are dispersed in water in a pressure-resistant container 1 and then heated at a temperature below the softening temperature (of the thermoplastic resin containing the blowing agent) plus 50 deg.C by a heater 4. Furthermore, while keeping the internal pressure of the container at a pressure below the vapor pressure (of the blowing agent) plus 30kg/cm<2> (guage), the mixture inside the container is discharged to a conduit pipe 8 or a container 9 having a free space larger than the flying locus of the expanded granules discharged or a lower free space than the internal pressure of the container from a discharge port provided to an orifice plate 7 after a discharge valve 6 leading to the inside of the container. Thus, objective pre-expanded resin granules 10 can be obtained.

Title: Combustion device
Inventor: UNO KATSUHIKO
IPC: F23D3/10
Filed: 1986-04-09
Abstract: PURPOSE:To control an amount of air to be supplied to an air passage, restrict an occurrence of yellow flame within a combustion chamber and restrict a leakage of unburnt gas from the combustion chamber into the air passage and to prevent a deterioration of combustion characteristic under a weak combustion by a method wherein a small diameter part is formed at an upper part of an outer cylinder. CONSTITUTION:Since a small diameter part 14 is made to have a desired height area, an amount of supplying air to be supplied to an air passage 19 through a small diameter part 14 of an outer cylinder 13 is controlled and at the same time its flow is restricted. Its flow is directed upward along a wall surface of a red heated part 11 as indicated by a white arrow A and mainly supplied from an upper part of the red heated part 11 to a combustion chamber 8. Therefore, air supplied from the lower part of the red heated part 11 to the combustion chamber 8 is relatively low in its volume, flame formed within the combustion chamber 8 is covered by an air layer and so no yellow flame is generated. Even in the case that an exposed height of a wick 1 is lowered and an amount of combustion is reduced to a lower value to cause the flame to be dropped into the combustion chamber 8 to show a state of (fs), an amount of unburnt gas discharged from a through-pass hole 12 above the flame (fs) into the surrounding atmosphere decreases and thus it is possible to prevent a deterioration of a combustion characteristic.
