Pulsed neutron scattering technique was started at the Nuclear Physics Laboratory (NPL) of Tohoku University 50 years ago. In this article, we overview the development of instruments from NPL, KENS, ISIS to J-PARC, which have been mainly used for studying highly correlated electron system. Deployment of the position sensitive detector is a most significant aspect to enhance the ability of instruments at pulsed neutron source. Also, chopper instruments have been a main contributor to the relevant scientific development.
