Filed: 1989-01-25
Abstract: PURPOSE:To make unnecessary the filling of back filling agent after the insertion of a spiral pipe in an existing pipe and consequently contrive to shorten the term of lining works by a method wherein the back filling agent, which is made of one-pack type expandable urethane resin and expands and hardens by moisture, is provided along the outer peripheral surface of the spiral pipe inserting in the existing pipe. CONSTITUTION:A pipe-making machine 20 spirally winds band-like body. At this time, the engaging rib 13 of the band-like body 10 fits in the socket 14 of the band-like body 10, which is spirally wound so as to engage side edge parts, which are adjacent to each other, of the band-like body with each other. At this time, an inclined rib 15, which continuously connects to the socket 14, is fastened to the flange part 16b of a reinforcing rib 16 and, at the same time, an abutting part 17 is put on a portion between the engaging rib 13 and the reinforcing rib 16 of a base plate 12. Back filling agent is applied onto the outer peripheral surface of the base plate 12 of the band-like body 10, which is formed to a spiral pipe 10'. As the back filling agent, one-pack type expandable urethane resin, which expands and hardens by moisture, is exampled. Its expansion starting time and expansion ratio can be controlled by properly changing the mixing ratio of auxiliary agent. After that, the expandable back filling agent expands so as to fill the gap between the spiral pipe 10' and the existing pipe 81.

Title: Measuring apparatus of glossiness of painted surface
Inventor: SAKAKIBARA MASATO
IPC: G01N21/57
Filed: 1990-01-25
Abstract: PURPOSE:To measure the glossiness correctly whichever color has the painted surface by photographing dark and bright patterns formed by a projecting means on the painted surface and extracting only a predetermined amount of level signals at the larger side generated from a photographing means. CONSTITUTION:An image of the dark and bright patterns formed on a painted surface by a pattern projecting means M1 is photographed as a level signal indicative of the level of the light by a pickup means M2. Only a predetermined amount of level signals at the larger side among the level signals output from the pickup means M2 is extracted by a peak average value calculating means M3. The average of the extracted values is set as a peak average value. Further, the brightness of a light source M1a possessed by the projecting means M1 is detected by a light amount detecting means M4. In general, when a light having the light amount of 11 is incident upon a plane and a light having the light amount 12 is reflected from the plane, if an angle of incidence is constant, the glossiness is proportional to 12/11. Therefore, the glossiness of the painted surface is detected by a glossiness detecting means M5 in accordance with the ratio between the peak average value and brightness of the light source M1a.
