摘要:
The present invention discloses a cut wire method of producing a ferrous shot and a cut-wire type ferrous shot for shot-blasting having a hardness of Hv 200 to 300 and a low work hardening ability. Further, the present invention describes a process of using a cut-wire type ferrous shots, comprising preparing the cut-wire type ferrous shots and a ferrous object and projecting the shots to the ferrous object to remove foreign material from the ferrous object.

A shot peening apparatus 1 includes: a storage container 2 that stores therein shots B impacting on a shot-peening treated region U; a vibrator 5 that accelerates the shots B; a shot outlet 4 that is formed on the storage container 2, and connected to a shot collecting passage 10 through which the shots B in a container inside 2I are collected, and through which the shots B are taken out from the container inside 2I into the shot collecting passage 10; and a shot inlet 3 that is formed on the storage container 2, and connected to a shot supplying passage 9 through which the shots B are supplied into the container inside 2I, and through which the shots B are supplied into the container inside 2I from the shot supplying passage 9.
摘要:
A positron annihilation characteristics measurement system 10 comprises a positron source; radiation detection means 14 for detecting radiation emitted when a positron generated by the positron source is annihilated; and a positron detector 40 that detects a positron that is not injected into a measured sample S after being generated by the positron source. The positron source is disposed between the measured sample S and the positron detector. An arithmetic device 50 calculates the annihilation characteristics of the positron in the measured sample S after eliminating the radiation that is detected by the radiation detection means 14 and is expected to be emitted when the positron detected by the positron detector 40 is annihilated.
