原始摘要(英文原文)· Original abstract
Unlike manufacturing technologies, Information Technology (IT) plays a unique role within organizations by shaping processes through continuous interaction with systems. During Japan’s industrialization era in the 1980s, machinery served as the driving force behind the growth of the electronics sector; however, structural disparities created a gap between manufacturing technologies and IT integration. As economies began to transition into information societies, IT often failed to align effectively with organizational structures. Consequently, this constrained growth and hindered operational advancement. This misalignment slowed the pace of Research and Development (R&D) within Japan’s electrical and machinery sectors, leading to a stagnation in the intensity of innovation. Supported by simulation and experimental validation, this study introduces a practical diagnostic technique for detecting inter-turn insulation faults in AC circuits. Its simplicity makes it highly suitable for application in industrial machinery. Furthermore, mechanical faults—such as bearing failures—are inherently associated with vibrations; this underscores the importance of integrating such measurements into maintenance decision-making processes. Investment patterns reveal that family-owned firms within Japan’s electrical machinery sector invest more aggressively than their non-family counterparts. This reflects a higher risk-taking propensity and fewer agency conflicts. Meanwhile, India’s machinery industry—despite possessing comparable equipment—faces challenges stemming from both internal operational inefficiencies and external market pressures. Government initiatives and Foreign Direct Investment (FDI)—particularly capital inflows channeled through multinational corporations—are expected to play a key role in enhancing the capabilities and competitiveness of this sector.
