    摘要: The present invention relates to a line module protection method and a device utilizing that method. According to the line module protection method of the present invention, line module protection is performed by switching the connection from a broken line accommodating module to an auxiliary module. A plurality of line accommodating modules are included in a line accommodating unit connected to the lines in a network. The plurality of line accommodating modules are divided into a plurality of groups, and the auxiliary module is placed substantially at the same distance from all the groups. Thus, a large number of line accommodating modules for performing line module protection can be employed with one auxiliary module.

    摘要: A signal processing device for analog-to-digital converting a burst signal has a feature of selecting a data bus to notify a disk control device of a conversion result via an NRZ data bus. The disk control device stores the result of the analog-to-digital conversion of the servo positional signal. The positional signal of a head of the disk device is digitized in a R/W channel. Sampling for digital conversion is performed in only a window which is defined only in the vicinity of peaks of the positional signal. The values of peaks which are obtained by sampling are averaged by an averaging circuit. This enables the influence of noise occurred outside of the window to be eliminated. Although the noise in the window is sampled, its adverse influence is suppressed by the averaging processing.

    摘要: In the composition of a Ag alloy type material used for production of flutes, a specified amount of at least one of Ni, Fe, Co and Cr or at least one of Mn, Ti, Zi and Si is added to suppress softening and crystal grain size coarsening caused by annealing in production. Thus, flutes which generate brilliant sounds in mid to high notes can be obtained by using the above material.
