Inventor: NAGASAKA KOJI
IPC: C08J9/35
Filed: 1990-03-12
Abstract: PURPOSE:To obtain the subject composite porous body having various colors, etc., to give a good appearance, by removing a pore-forming material from a product prepared by reacting a salt aqueous solution-impregnated polyvinyl acetal porous body with a specific reaction raw solution having approximately the same specific gravity as the apparent specific gravity of the porous material in the presence of a catalyst. CONSTITUTION:A reaction raw solution comprising polyvinyl alcohol having an average polymerization degree of 300-30000 and a saponification degree of 80mol%, a pore-forming material preferably comprising starch extracted from a plant and a crosslinking agent such as formaldehyde is mixed with a catalyst such as hydrochloric acid and subsequently with a polyvinyl acetal porous body sufficiently impregnated with a salt aqueous solution such as sodium sulfate aqueous solution and having a specific gravity (specific gravity of 1.01-1.20) approximately the same or slightly higher as or than that of the reaction raw solution. The mixture is thermally subjected to a crosslinking reaction and the reaction product is taken out and washed with water to provide the objective composite porous body.

Title: Apparatus for inspecting burr of object to be inspected
Inventor: SEKIGUCHI SHINGO
IPC: G01B11/30
Filed: 1987-03-19
Abstract: PURPOSE:To judge a flaw at a high speed, by picking up only the burr part of an object to be inspected as a shade and extracting a flaw part by the binarization and thinning of the image pickup signal of the burr part. CONSTITUTION:A diffusion plate 2 allows the light from a lower light source to diffuse to allow the whole of an object 1 to be inspected to appear as a shade. An upper light source 4 illuminates the upper surface of the object 1 to leave the burr 5 at the bottom part of the object in a shade state. The image pickup signal obtained by a camera 6 is binarized by the binarization circuit 8 of an image processor 7 and only the part of the burr 5 is extracted. Continuously, the part of the burr 5 extracted by a thinning circuit 9 is thinned and, at this time, a flaw part exceeding the tolerance range of the burr 5 appears as a part markedly protruding from other part. This signal is sent to a 3X3 flaw detection filter 10 and, when the signal coincides with a flaw mask A (at the time of an end point) or a flaw mask B (a line width is other than 1), the product is determined as defective.

Abstract: PURPOSE:To prevent a fault occurring at the time of breaking by detecting a virtual circuit breaking signal via a communication controller set at the communication equipment side to change partially a control signal to an interface port part of the communication equipment connected to said communication controller itself for output of a port control signal. CONSTITUTION:A virtual circuit VC breaking signal is applied to a communication controller 10 from an equipment of the remote side which is performing communication after setting up a VC through a transport layer TR in a CCU 12 via a line, a drop cable (c) and a MODEM 13.

Abstract: PURPOSE:To improve the effect of heating by lowering the performance of heat insulation at a position where a person, etc. get on while enhancing heat-insulating property by elevating the performance of heat insulation at other portions, and to save power by setting a surface material up on the surface of a heating element through a compression layer of a large compressive deformation rate. CONSTITUTION:The surface material 3 is formed on the surface of the heating element 1 through the compression layer 2, and the back of the heating element 1 is coated with a back material 4. The compression layer 2 is formed by the quality of material of the large compressive deformation rate such as foamed urethane. Accordingly, the compression layer 2 functions as a heat-insulating layer, inhibits heat transfer to the surface material 3 from the heating element 1 and reduces a temperature rise of the surface of the surface material 3 and radiation to space from the surface material 3. When a person sits on the surface material 3, on the other hand, a distance between the person and the heating element 1 is brought close and heat is transmitted sufficiently to the person because the compression layer 2 is compressed only by said section.
