Filed: 1990-04-25
Abstract: PURPOSE:To expand a stormwater-permeable area by providing a stormwater flow hole at the bottom of the side wall of a side drain, a stormwater-permeable layer comprising superposed layers of spherical molded items connected to the hole, and a sand filtration layer over the stormwater-permeable layer. CONSTITUTION:A concrete layer 5, as a sand filtration layer, is provided between a stormwater-permeable layer 3 and an underground layer 12 to prevent sand to fall down onto the layer 3 from the layer 12. The stormwater flowing in a side drain 2 flows through storm water flow holes 25 into the layer 3 and then smoothly flows along the arcuate-upstanding surface of a wire-mesh cage 4 and hence deposite of sand, which causes clogging in the layer 3, is avoided. Since the layer 3 is composed of spherical molded items 30, resistance to the flow of stormwater is small and stormwater evenly penetrates through the layer 3. As a result, stormwater can be passed through the underground over a wide area.

Title: Intermediate heat exchanger
Inventor: MITSUMA KOTARO
IPC: F28F9/02
Filed: 1985-05-24
Abstract: PURPOSE:To reduce temperature difference between a heat transfer tube and a tube plate to mitigate thermal stress by a method wherein the heat transfer tube penetrating hole of tube plate is formed with a small diametral section at the upper side of the hole and a large diametral section at the lower side of the same to change the diameter thereof in the direction of thickness of the plate while a gap, produced between the tube plate and the heat transfer tube, is filled, with heat insulating material. CONSTITUTION:A part of the tube plate 20 around the heat transfer tube 21 is cut to provide the gap 39 between the heat transfer tube 21 and the tube plate 20 while the gap 39 is filled with the heat insulating material 37, employing a material having a heat transferability inferior to the same of stainless steel or the material of the tube plate, in case it is desirable. The heat transfer performance in this case is deteriorated considerably as compared with the case wherein the heat transfer tube 21 is contacted wholely with the tube plate 20 directly through metal contact. Accordingly, the temperature variation of the tube plate 20 follows the temperature variation of a cooling material with some delay while the temperature variation of an outer cylinder 19 is delayed to the temperature variation of the cooling material since the heat transfer property of the stainless steel is low substantially. According to these relations, the temperature difference between the heat transfer tube and the tube plate may be reduced remarkably and the thermal stress, generated as the result of the temperature difference, may be mitigated.
