Purpose: Sustainable functionality development (FD) is decisive to firm's profitability in their new innovation in a competitive market. While functionality instills attractive values in innovative goods leading to a dramatic increase in profit through increasing demand and higher prices, it obsolesces immediately in a competitive market. Therefore, how to maintain sustainable FD trajectory is decisive to firm survival strategy within the context of mega‐competition in a globalizing economy. Notwithstanding an increasing significance of this subject, dynamism enabling a sustainable FD trajectory still remains inside a black box. The purpose of this paper, on the basis of an empirical comparative analysis of the diffusion trajectories for copying machines developed by Canon and Ricoh, is to attempt to elucidate this dynamism. Design/methodology/approach: This paper employed a bi‐logistic growth model utilizing patent data for copying machine technologies. Findings: It was found that early undertaking of 2nd generational copying machinery initiated by Canon played a more decisive role in terms of its higher level of sustainable FD than with its competitor. Originality/value: This paper provides significant insight to firm's management of technology strategy in a competitive market.

The purpose of this paper is to develop a ferromagnetic needle adaptable for a novel ablation cancer therapy; the heat generation ability of the mild steel rod embedded into the Ti‐tube having a different thickness was investigated in a high‐frequency output at 300 kHz.
The outer diameter and length of the Ti‐tubes were 1.8 and 20 mm, respectively, while the inner diameter was varied from 1.6 to 0 mm. The mild steel rod was embedded in a Ti‐tube for preparing the needle‐type specimen. Their heat generation ability was examined by changing the inclination angle to the magnetic flux direction in a high‐frequency coil.
When the thickness of the Ti surrounding the mild steel rod was as low as 0.1 mm, the heat generation ability was drastically different among the three inclination angles (θ=0°, 45°, and 90°) to the magnetic flux direction due to the effect of the shape‐induced magnetic anisotropy. However, the effect of the inclination angle was almost eliminated in the specimen surrounded by the 0.4 mm thick Ti, suggesting that the non‐oriented heat generation property is achieved for the needle‐type mild steel rod coated with Ti having the optimum thickness.
The prototype ablation needle having a complete non‐oriented heat generation ability was fabricated to use in subsequent animal experiments. It is considered that the newly designed Ti‐coated device is useful in ablation treatments using a high‐frequency induction heating.

A virtuous cycle between effective utilization of external resources and functionality development can be constructed. Given that the timely emergence of new functionality in an efficient way is crucial to a firm's competitive strategy in an era of mega‐competition, construction of such a virtuous cycle is a key element with regard to a firm's technopreneurial strategy. The purpose of this paper is to identify a trigger for such a virtuous cycle.
Empirical comparative analysis taking copying machines development trajectories in Canon and Ricoh and the patent data analysis were conducted.
Cumulative learning from preceding relevant technology development is found to stimulate intra‐technology spillover. Timely intra‐technology spillover from preceding innovation plays a triggering role.
Attempting a broad and comprehensive learning exercise should be strongly encouraged for the effective utilization of external resources for innovation. Fruitful effects of learning should be pursued to the hybrid management of technology fusing indigenous strength and the effects of the comprehensive learning.
Aiming at identifying the trigger emerging a virtuous cycle between effective utilization of external resources and functionality development, core technologies instilled in the copying machines just short of the emergence of functionality development were investigated. In order to anticipate thorough capturing of all dimensions of color technologies utilized for the emergence of new functionality development through indigenous development as well as utilization of externally developed technologies, F‐term retrieval of patent registration data was attempted.

Japan’s chemical industry is currently amidst mega‐competition in the paradigm shift from an industrial society to an information society that emerged in the 1990s and consequent globalizing economy. The checkered development trajectory of Japan’s chemical industry has resulted in a fragile structure with increasing geographical constraints and excessive competition in certain markets among a number of small‐scale firms. A simultaneous solution to divergent activities for diversified customer requirements as well as dynamically changing external circumstances and convergence for improving competitiveness in core competent fields is thus essential. This paper attempts to identify an optimal trajectory for Japan’s chemical industry by providing a simultaneous solution to the above contradicting demands. A resilient structure that incorporates an optimal level of diversification based on a specific reinforced core competent field is postulated as a survival strategy in a business environment characterized by mega‐competition. Aiming at demonstrating the significance of a resilience structure, an empirical analysis focusing on Japan’s 28 leading chemical firms was conducted. An optimal level of technological diversification for Japan’s chemical industry firms was thereby identified, thus leading to construction of a resilient structure.
