Title: Manufacture of test body
Inventor: IWAKI TAKASHI
IPC: G01N1/00
Filed: 1983-12-15
Abstract: PURPOSE:To manufacture various test body with an artificial defect easily in quantities by welding blocks in an optional shape with an electron beam so that unwelded parts form a gap. CONSTITUTION:Blocks 2a and 2b made of a magnetic body are welded with the electron beam 3 and welding conditions are made different from others where the gap is formed to reduce the welding depth. The welding of one surface is completed and then similar welding is carried out from the opposite surface to form a gap 8 as an artificial fault in the test body 1. Welding conditions of electron beam welding such as a beam acceleration voltage, beam current, and welding speed are varied to obtain optical welding depth with good reproducibility, and the strain of a welded body is small, so the application of this welding technique facilitates the large-quantity production of various test bodies. Those test bodies are used for testing the skill of a magnetic power flaw detecting inspector.

Abstract: PURPOSE:To shorten fast forwarding and rewinding time by taking up a magnetic tape in rotating one reel of either a supply reel or a take-up reel at low speed at the initial stage, taking up the magnetic tape in rotating the reel at high speed under specific condition and restoring the magnetic tape to the previous take-up state in rotating the reel at the low speed again but still under the specific condition. CONSTITUTION:When the fast forwarding mode becomes effective, low speed revolution is taken place, and at this time, a revolution frequency ft of the take-up reel 8 and a revolution frequency fs of the supply reel 7 are detected and compared with each other, and if ft>fs, it can be decided that a tape amt. winding around the reel 8 is less than the supply reel 7, so as to make the reel revolution speed at the high speed. In this case, ft/fs is calculated. Then, a revolution frequency Ft of the take-up reel 8 and a revolution frequency Fs of the supply reel 7 at the time of the high speed revolution respectively are detected, and they are returned to the low speed revolutions again from the point where the condition of ft/fs<=Fs/Ft is satisfied. By this method, the fast forwarding and rewinding can be performed at high speed, thus shortening the time respectively.
