Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: The present invention provides a parts information management method and a parts information management system which allows efficient and optimal activities to be done when developing and improving a product. The parts information network in a specific organization is integrated with the parts information network outside the organization. The input device of a network terminal may be used to input information with respect to part specifications to be searched. Any parts which satisfy the input specification are gathered from the parts information network. Then the display device of a network terminal may be used to list a plurality of parts in the predetermined priority order. The priority may be determined based on the distribution records so as to place the examination results in the specific organization at the top priority.
