Title: Sheath coating method for metallic body by synthetic resin layer
Inventor: HENDORIIKU KOOPUMAN
IPC: F16L57/00
Filed: 1982-08-20
Abstract: A method of externally convering metal objects, for example tubes with a synthetic resin layer, in which tape-shaped coating material is wound with a resin around the tube (1), subsequently the tube is heated and after curing of the resin the tube is allowed to cool down. During the winding operation the tube is maintained approximately at room temperature and after the winding operation the tube is gradually heated up to a medium temperature range. By heating the tube itself the resin is gradually heated by the tube, so that the resin is slowly and evenly along the length of the tube becoming soft and fluid. Since the heating energy is for the larger part taken up by the tube the temperature rise of the resin coating is very stable.

Filed: 1995-06-12
Abstract: PURPOSE: To provide an image coding control method and a control circuit conducting coding control making a generated information amount constant while changing the image quality of a specific area of an image. CONSTITUTION: An original image is divided into some blocks and a quantization step calculation section 9 decides a quantization step 15 of an orthogonal transformation coefficient in each block by using a difference between an object information quantity 1 and a generated information amount 4. A calculation section 9 prepares a table 12 storing data of a parameter designating the image quality of each block in advance and references the table 12 in the case of applying coding control to each block and a quantization step is changed so as to be proportional to the data of a concerned block.  Thus, while conducting the image quality control such that the quantization step is reduced to enhance the image quality in the case of a block with a small data amount and the quantization step is increased to suppress the image quality in the case of a block with a large data amount, the generated information amount 4 is controlled simultaneously.
