Title: Apparatus for fixing substrate for thermal spraying
Inventor: KITAHARA SHIGERU
IPC: C23C4/12
Filed: 1984-03-17
Abstract: PURPOSE:To form a fine sprayed film even by spraying with high energy by providing unevenness to the surface of a backing die having the same shape as a substrate for spraying to form paths from which expanded air escapes. CONSTITUTION:The surface of a backing die 9 having the same shape as a substrate 1 for spraying such as curved metallic foil of 20-200mum thickness is made uneven to form paths 10 from which air in the gap between the substrate 1 and the die 9 escapes. The substrate 1 is then fixed on the die 9, and powder or the like is sprayed on the substrate 1 to form uniformly a sprayed film. At this time, expanded air is discharged to the outside A through the paths 10 to prevent the deformation of the substrate 1. The resulting film 5 is firmly adhered to the substrate 1 and has a high modulus of specific elasticity.

IPC: B01D39/16
Filed: 1997-03-06
Abstract: PROBLEM TO BE SOLVED: To make acid resistance and laminating property of a cloth compatible by forming a bag filter from a porous composite body formed by laminating a porous PTFE film on one surface of the water and oil repellently treated cloth through spotty contact faces. SOLUTION: For the bag filter used for a dust collector or the like, the porous composite body formed by laminating the porous polytetrafluoroethylene(PEFE) film 11 on one surface of the water and oil repellently treated cloth through the spotty contact faces is used. In such a case, the spotty contact faces are preferably contact faces generated by flame-treating the cloth 13 and the flame treatment means that one surface of the cloth of a thermally melting type base material is heated at the moment to a temp. of more than the melting point by flame of propane gas or the like. Many fine spherical pills 12 are formed since the fiber on the cloth 13 surface is partially melt by treating with flame in this way and the melted based material shrinks with surface tension and then the surface of the pills 12 loses the water and oil repellent effect.
