This invention provided a high-build, self-polishing marine antifouling paint which affords a coated film having antifouling properties for a long period of time. The paint binder which is a fiber reinforced aldehyde resin comprises two synergistically acting components, Component A and Component B. Component A an aluminium di-sec-alkoxide ace-toacetic ester chelate is represented by the following formula (1): (R.sup.1O).sub.2--Al--(CH.sub.3--CO--CH.sub.2--CO--O--R.sup.2) wherein R.sup.1 represe...

A translator is connected to a first network for transferring data in a first protocol, to a second network for transferring data in a second protocol, and to a translation server to which other translators are connected, for retaining translation information for a protocol translation between the first protocol and the second protocol. The translator generates a second address in the first protocol corresponding to a first address in the second protocol provided to a terminal accommodated in th...

A functional block for verifying correct interface operation of any functional block is generated from interface description and installed on a LSI chip. To accomplish this, from the interface description, hardware description of a synthesizable interface checker is generated. Means for selecting interface functions to be checked is provided, thereby making it possible to reduce the overhead of circuits to be installed on the LSI.
