Filed: 1987-07-07
Abstract: PURPOSE:To realize wide-range usage and deflection characteristics corresponding to the kinds of machines by clamping an adjusting plate and a frame by a holding means and rotating and moving the adjusting plate on the surface of a frame. CONSTITUTION:The center part of the plane part 3 of the frame 2 is clamped by the holding means 15 together with the nearly discoid adjusting plate 14. The means 15 consists of a rivet 16 and a pressure plate 17 and presses the plate 14 strongly against the plane part 3 so that the plate 14 moves on the surface of the plane part 3. Further, a lock piece 19 which engages a groove 18 made in the plane part 3 is provided to one side of the plate 17 so that the plate 17 rotates. The hole 20 of the plate 14 into which the rivet 16 is inserted is formed to a larger diameter.

Title: Manufacturing method of heat shrinkable polypropylene film
Inventor: SHIBATA YOSHIZO
IPC: B29C55/14
Filed: 1984-08-13
Abstract: PURPOSE:To obtain heat shrinkable polypropylene film, which has balanced physical strengths in both longitudinal and laternal directions of the film and at the same time has a larger heat shrinkability in only one direction, by a method wherein, firstly, original film sheet is stretched in one direction and, after that, heat-treated and finally further stretched in the direction normal to the direction of the first stretching. CONSTITUTION:Larger physical strength is given in the direction of stretching by stretching in one direction at the first stage. Next, the heat shrinkage due to the stretching at the first stage is suppressed by crystallizing the polypropylene resin through the application of heat treatment to said monoaxially stretched film. By being given heat shrinkability by being successively stretched at the second stage in the direction normal to the direction of the first stretching, the film with balanced physical strengths in both longitudinal and lateral directions of the film and at the same time with a larger heat shrinkability in only one direction is obtained.

The thus generated fluorescence or phosphorescence is spectrally split by a spectroscope 8 in a 400-650nm wavelength range. The intensity of the fluorescence or phosphorescence of such wavelength range is converted to an electric signal by a photoelectron multiplier 9. After the signal is amplified 12, the signal is fed to a boxcar integrator 13 and is measured at 10-100musec time width upon lapse of 1-30musec after the pulse laser projection. The result thereof is displayed and recorded on a synchroscope 14 and recorder 15. The peak intensity or peak area indicating the max. intensity is calculated and is compared with a preliminarily formed calibration curve or the standard sample of a known concn., by which the uranium content is calculated.
