摘要： In a magnetic disk controller equipped with a cache memory for disks, the controller in accordance with the present invention includes high order paths for data transfer between a high order channel apparatus and the cache memory through a certain one of a plurality of channel adaptors, low order paths for data transfer between a low order device, e.g. a magnetic disk device, and the cache memory through a certain one of a plurality of device adaptors and a path for data transfer betweeen the low order device and the channel cevice without passing through the cache memory by selecting empty device adaptor and channel adaptor by the switching operation of a switch. When an interrupt is generated from the device, data transfer can be made easily even when the high order path and the low order path are busy, and path utilization efficiency can be improved.

摘要： Cypoviruses and baculoviruses are notoriously difficult to eradicate because the virus particles are embedded in micron-sized protein crystals called polyhedra. The remarkable stability of polyhedra means that like bacterial spores these insect viruses remain infectious for years in soil. Although these unique in vivo protein crystals have been extensively characterized since the early 1900s, their atomic organization remains elusive. Here we describe the 2 crystal structure of both recombinant and infectious silkworm cypovirus polyhedra determined using 5-12 micron crystals purified from insect cells. These are the smallest crystals yet used for de novo X-ray protein structure determination. It was found that polyhedra are made of trimers of the viral polyhedrin protein and contain nucleotides. Although the shape of these building blocks is reminiscent of some capsid trimers, polyhedrin has a new fold and has evolved to assemble in vivo into 3-D cubic crystals rather than icosahedral shells. The polyhedrin trimers are extensively cross-linked in polyhedra by non-covalent interactions and pack with an exquisite molecular complementarity similar to that of antigen-antibody complexes. The resulting ultra-stable and sealed crystals shield the virus particles from environmental damage. The structure suggests that polyhedra can serve as the basis for the development of robust and versatile nanoparticles for biotechnological applications such as in cell culture systems, microarrays and biopesticides.
