Abstract
A new continuous hard chromium plating process for plating long steel bars has been developed. The process is an application of the reduced pressure method, where the chromium electrolysis takes place in a separated process chamber under a pressure reduction of about 50 kPa.

Abstract
Purpose
The purpose of this paper is to consider the thermal‐physiological comfort performances of a sport shirt made of a polyester (PES) fabric with incorporated activated carbon. After having characterized the modified PES fabric in Part I, the results of a wear trial campaign are shown and discussed in this work.
Design/methodology/approach
The wear trials have been carried out under a controlled physical activity. A short‐and‐intense effort and an intermittent effort of milder intensity were carried out twice by each volunteer: once wearing a shirt made of the modified PES fabric and the other one wearing an analogous shirt made of a conventional PES fabric.
Findings
When sweating was moderate, the modified PES shirt was judged as more comfortable on the average. As the effort became harder, the modified PES fabric turned out to be less comfortable than the conventional one. In the final recovery stage, the conventional PES was still more comfortable than the modified PES. This behaviour was justified according to the findings of Part I: at the beginning, the prevailing effect was the adsorbing ability of carbon particles that buffer sweat impulses, giving the user a pleasant dry sensation. Then, when sweating became intense, the lower evaporative cooling of the modified PES fabric became the key factor governing the physiological comfort of the garment. This is confirmed by a slightly higher skin temperature measured during the modified PES fabric trials. Finally, a post‐exercise chill sensation was felt with the modified PES fabric, due to a longer drying time.
Originality/value
The paper presents a comprehensive study of the thermo‐physiological comfort of a fabric containing activated carbon particles.

Abstract
Purpose
The purpose of this paper is to analyze the development of body fitness equipment in Taiwan from the viewpoint of innovation and the factor of success for innovation.
Design/methodology/approach
The research methods include a literature study and a case study. In addition, the innovation activity of an enterprise is based on the viewpoint of procedure (input‐process‐output). The innovation activity of an enterprise is separated into three phases: innovation motivation, innovation process, and innovation performance.
Findings
The enterprise's competitive advantage and efficiency can clearly be seen, and the reason for the enterprise's success can easily be identified through a structural analysis of the innovation process. The research results indicate four factors for the success of Johnson: mastering technology, good management, employment of diversified talents, and clear brand positioning.
Research limitations/implications
The innovation research model provides a comprehensive summary of the innovation process, stressing innovation activity. The study of the factors of success does not establish quantified or non‐quantified innovation indicators.
Practical implications
The factor of success of innovation is not exactly the same for every company. Sorting and analyzing the individual cases can serve as a basis of reference and act as a guidepost for other companies in similar industries during their business development.
Originality/value
The analysis model of innovation activity can clearly explore the development process of the innovation success of an enterprise. Simultaneously, this research can serve as a role model for other companies when they innovate.
