Disclosed is an insulating polymer material composition of the environment-conscious type which is obtained by using a renewable resource and a waste material as starting materials. A plant oil-origin epoxy resin is mixed with a plant-origin polyphenol and the obtained mixture is subjected to a heat treatment to give a liquid epoxy resin composition which is a compatibilized blend of the plant oil-origin epoxy resin and the plant-origin polyphenol. To this liquid epoxy resin composition, coal ash and a silane coupling agent are added followed by mixing. Further, an additive such as a curing accelerator is added thereto and the mixture is subjected to a heat treatment to give an insulating polymer material composition. As the coal ash, it is preferred to use fly ash. It is also preferred to use a silane coupling agent having epoxy group.

CONSTRUCTION METHOD FOR IMPROVING EARTHQUAKE RESISTANCE OF EXISTING SLUICE GATE PILLARS PROVIDED TO DAM, AND EARTHQUAKE-PROOF BRIDGE FOR DAM
Existing sluice gate pillars (31-35) are structures which are located on both sides of gates (G1, G2), and support an existing operational bridge (40) which comprises steel main beams (50A, 50B) and the gates (G1, G2). Disclosed is a method for improving the earthquake resistance of the existing sluice gate pillars (31-35) provided to a dam. This method includes a process wherein, in all spans of the existing operational bridge (40), those ends of the main beams (50A, 50B) at which movable bearing structures are located, are connected, by means of high damping dampers (70) having high first-order rigidity hysteresis characteristics, to the tops of those existing sluice gate pillars (31-35) at which the movable bearing structures are located; and a process wherein the yield load value of the aforementioned high damping dampers at a seismic velocity is set to a value higher than a maximum seismic force generated by a large-scale earthquake in the bridge axis direction of the high damping dampers. The aforementioned maximum seismic force generated by the large-scale earthquake in the bridge axis direction of the high damping dampers is received in regions of high first-order rigidity prior to a stage where the hysteresis damping characteristics of the high damping dampers come into play.

Abstract
By covering the inner circumferential surface of an outer cylinder with a vapor film, thermal conductivity is reduced and the phenomenon of sudden temperature increases in the cylinder wall of the outer cylinder can be prevented, thereby preventing heat damage to the outer cylinder. Additionally, burner burnout, caused by insufficient cooling resulting from irregularities in cooling efficiency at the burner tip, is also prevented. A tip, which is positioned inside a two-stage entrained-flow bed coal gasification furnace, has a double-walled cylindrical structure with an outer cylinder and an inner cylinder, and is configured so that cooling water to cool the tip is supplied via the inside of the inner cylinder and, after cooling the tip, is returned to the base end via the space formed between the outer cylinder and the inner cylinder, and is additionally configured so that the flow path surface area of the space formed between the outer cylinder and the inner cylinder is less than the flow path surface area formed inside the inner cylinder, thus configured so that a swirling flow along guides formed on the outer circumferential surface of the inner cylinder, and a roughly linear flow in the lengthwise direction of the outer cylinder and the inner cylinder, are imparted to the cooling water that is returning to the base end via the space formed between the outer cylinder and the inner cylinder.

Abstract
A compressor having extended service life. An evaporator has a housing having a suction opening capable of being connected to a suction section of a compressor and evaporates at least a part of droplet-like or mist-like working liquid in the housing by using sucking action of the compressor performed through the suction opening. In the housing is placed a filter for separating a first space for producing the droplet-like or mist-like working liquid and a second space communicating with the suction opening. The filter is placed inclined such that the nearer the upper part of the housing, the further from the suction opening, and the filter allows vapor evaporated from the drop-like or mist-like working liquid to permeate through the filter and captures the drop-like or mist-like working liquid.

Abstract
A condenser having two deaeration chambers separated by cooling water, wherein both the deaeration chambers are prevented from communicating with each other even if the pressure difference between the deaeration chambers increases. The condenser has a housing and a flow section. The housing has in it a first deaeration chamber and a second deaeration chamber. The first deaeration chamber has a vapor inlet opening capable of being connected to a discharge section of the compressor and communicates with the vapor inlet opening. The second deaeration chamber is placed above the first deaeration chamber with a partition section in between. The flow section causes the cooling liquid to flow from the second deaeration chamber to the first deaeration chamber. The first and second deaeration chambers are separated by the cooling liquid in the flow section. The flow section has a pressure head chamber for receiving the cooling liquid of a specific volume absorbing a variation in the pressure difference between the first and second deaeration chambers.
