摘要： High transparency silica-titania glass beads are characterized by a linear transmittance of at least 70% as measured at a wavelength of 900 nm to 600 nm by a specific measurement method. Such beads are prepared by hydrolyzing and polycondensing a silicon alkoxide and a titanium alkoxide to form a silica-titania sol, converting the sol into a dry gel, and then grinding the gel followed by heating or heating the gel followed by grinding. A light transmisson epoxy resin composition comprising a curable epoxy resin, a curing agent, and the high tranparency silica-titania glass beads has crack resistance and high transparency in cured state. It is useful in encapsulating optical semiconductor devices.

摘要： In a cell exchange, cell diagnosis of continuity with respect to an individual part operating in a band width for a speed faster than a cell feeding speed is enabled by using cell test equipment with a low cell feeding speed. The method of cell diagnosis of continuity for this purpose comprises a step of setting a plurality of paths between a diagnosed unit to which the cell diagnosis of continuity is applied and the cell test equipment; a step of almost substantially concentrating cells sent from the cell test equipment through a plurality of paths at the diagnosed unit; and a step of returning cells concentrated at the diagnosed unit to the cell test equipment via one of a plurality of paths.

摘要： A method employs simple procedures to speedily carry out loopback tests on devices that form a channel system of an exchange. The method is capable of quickly locating a fault in the exchange and allowing speedy maintenance work of the exchange. Also provided is an apparatus for achieving the method. The apparatus has a path setter (1-4), a loopback controller (1-3), and a tester (1-1), to test the devices of the channel system (1-2) of the exchange. The devices to be tested are arranged in replaceable units (1-21, 1-22). The path setter (1-4) simultaneously sets paths to sequentially connect the devices to be tested. The loopback controller (1-3) activates and releases loopback parts arranged in the devices to be tested. The tester (1-1) sends a test signal to the devices through the paths, receives the test signal looped back by the loopback parts, analyzes the received signal, and determines whether or not the devices are sound.
