Abstract: A communication system in which a server-side system and a client-side system are communicably connected via a network, the server-side system including: an information reception unit that receives an input information packet including input information and loss chunk numbers from the client-side system; a video processing unit that generates video data; a chunking function unit that chunks the video data and assigns a number to each chunk; a chunk loss determination unit that calculates a chunk loss rate and determines a transmission interval on the basis of a transmission interval determination logic; and a transmission control unit that transmits the chunked video data to the client-side system.

Abstract: A management device of an accelerator management mechanism includes a workload management unit that manages correspondence information that associates each workload with an accelerator of a calculation node that may support the workload, and an accelerator management unit that receives an inquiry about a workload from a user terminal, acquires information of an accelerator of a calculation node that may support the workload of the inquiry with reference to the correspondence information, responds to the user terminal with the acquired information, and thereby offloads the workload of the inquiry from the user terminal to the accelerator of the calculation node for which the response has been made.

Abstract: A controller server (10) includes an assignment unit (11a) that assigns devices connected to a server to virtual machines managed by users, a usage status management unit (11b) that records correspondence between the virtual machines and devices used by the virtual machines, a warning relation management unit (11c) that records types of warnings that may occur for each of the devices during maintenance, a maintenance control unit (11d) that, upon accepting a maintenance request, determines an order of an instruction for suppressing issuance of a warning that may occur for the devices during maintenance and an instruction for evacuating an affected virtual machine affected by maintenance among the virtual machines to another server, a warning exclusion setting unit (11e) that instructs the server to exclude issuance of a warning that may occur for a device due to the maintenance, and an affected user specification evacuation unit (11f) that specifies the affected virtual machine on the basis of correspondence

Abstract: A cassette adapter which makes it possible for a second cassette which accommodates a circular wafer of a diameter of 200 mm to be used on a load port ready for a first cassette which accommodates a different circular wafer of another diameter of 300 mm is locked to the load port by an adapter main body locking apparatus. The locking apparatus includes a locking air cylinder serving as a locking member for locking the first cassette to a carrier base of the load port, and a locking target member provided integrally on a rear face of an adapter plate of the cassette adapter for disengageably engaging with a locking pawl at an end of a rod of the air cylinder. A seating sensor mechanism detects that the second cassette is seated at a correct position on the adapter plate.

Abstract: The thin-film electroluminescent device of the present invention comprises a thin film of a polyoxadiazole derivative represented by the formula: ##STR1## wherein each of X.sub.0 and Y.sub.0 independently represents a divalent organic group which may comprise a silicon atom, and n is an integer of 2 or greater,formed as an electroluminescent layer or a charge injecting/transporting layer between electrodes, at least one thereof being transparent. This thin-film electroluminescent device is excellent not only in electroluminescence and capability of charge injection/transport to thereby ensure high light emission efficiency but also in durability such as heat resistance.
