This invention relates to a method for the analysis of a target non-proteinaceous component of a mixture of non-proteinaceous and proteinaceous components derived from a biological sample using a protease from a Bacillus strain. In the method, management information for managing the hierarchical structure of the file system is recorded to a predetermined area of the disc shaped record medium. The power source circuit is coupled to the first and second transistors. Notification of the driver will take on a variety of forms depending on the stored information, current operating modes, and vehicle speed. The connecting bus bar 12 is formed such that the connecting bus bar 12, which excludes the negative weld plate section 27a and the positive weld plate section 28a, becomes lower in thickness than a thinner one of the closed end of the bottomed cylinder 13 and the seal plate 14.
