Title: Perforated film which is fluoride on surface and tube
IPC: F24F3/14
Filed: 1992-03-18
Abstract: PURPOSE:To manufacture a thin tube efficiently and at a low cost by a method wherein surface of a perforated film made of polyethylene or polypropylene is treated with fluorine gas to be fluoride. CONSTITUTION:A perforated film tube 4 made of polyethylene or polypropylene is airtight connected at a tip end 4a to a gas inlet 3a and at a rear end 4b to a gas outlet 3b respectively, and housed in a silica pipe 3 stretched in the axial direction. Fluorine gas generated by a fluorine generator 1 undergoes purification when passing through a calium fluoride trap 2 with hydrogen fluoride removed from it, and flows into the silica pipe 3. With respect to the tube 4 within the silica pipe 3, fluorine gas flows inside the tube 4 and atoms of something in the inner surface, for example, hydrogen atoms which form polyethylene are replaced with fluorine atoms. Thus, as the hydrogen atoms are changed, for a short time, into a fluoride which is very similar to polytetra- fluoloethylene not only in the structure but in the physical and chemical properties. By this, the thin perforated film tube 4 which is fluoride on surface can be manufactured very efficiently and at a low cost.

Title: Method for judging finishing temperature in rolling of steel material
Inventor: NAKAYAMA MASAHISA
IPC: G01K11/22
Filed: 1982-04-16
Abstract: PURPOSE:To detect the finishing temperature in rolling of a steel material, by using a contactless ultrasonic wave probe, and comparing and measuring sound speeds, which are propagating in the rolling direction and the direction which is perpendicular to the rolling direction. CONSTITUTION:A lateral wave, contactless ultrasonic wave probe 3 is arranged so that the vibrating direction of the ultrasonic wave forms an angle theta with the direction L of a steel material 2 in finishing roll. Lateral ultrasonic waves 4, which are inputted in the steel material 2, are transmitted in the direction of the thickness of a plate accompanying two vibrating modes, namely wave 5 vibrating in the direction L and wave 6 vibrating in the direction C. This is caused by sound speed anisotropy based on the texture of the steel material 2. The sound speed VL of the wave 5 vibrating in the direction L is faster than the sound speed VC of the wave 6 vibrating in the direction C. Two waveforms 8 and 9 are observed on a CRT tube 7 on an ultrasonic wave flaw detector. From wave propagating times W1 and W2, a sound speed ratio VL/VC= W2/W1 is obtained. The finishing temperature in rolling of the steel member 2 is detected from a measuring curve for the sound speed ratio of the finishing temperature for every steel material, which is measured in advance.
