In “Closed Innovation”, knowledge or information was created and stored in tightly integrated organizations. Their knowledge and information were the resources to be protected by companies. The concept of “Open Innovation” encourages companies to

Professor Toshiro Kita, Graduate School of Management, Doshisha University, Japan, believes a lack of understanding of the importance of business ambidexterity contributed to this difficult period for Japanese firms and that understanding and utilising ambidexterity could have significant benefits for businesses. Kita is interested in innovation management and the ways in which the application of ambidexterity can help businesses. He believes that businesses can thrive by adopting the Observe, Orient, Decide, Act (OODA) loop alongside the Plan-Do-Check-Act (PDCA) Cycle and his work also looks at other aspects of innovation management, such as entrepreneurship, disruptive innovation and corporate culture and cognitive bias, as well as innovation management in the context of COVID-19. This later strand of research involves looking at how ambidexterity can help businesses to thrive i...

In this paper, the influence of disk lubrication on the tribological characteristics of the head/disk interface is investigated by pin-on-disk wear tests and the head/disk friction tests.The anti-wear performance of a lubricant is very high. For example, a lubricant coating of 8.4 × 10 mg/cm exhibits 1/20 of the ferrite pin wear rate of an unlubricated disk. For a lubricated disk, ferrite pin wear decreases at increased sliding velocities as high as 10 m/s, while pin wear increases rapidly with increased velocity for an unlubricated disk. The lubricant used here performs well in suppressing the wear increase caused by increased load. Regarding friction characteristics, however, an excessive amount of lubricant induces severe head/disk sticking, causing head crash. With respect to head/disk sticking, the upper-limit of the amount of lubricant is 8.4 × 10 mg/cm.
