Abstract: A laser processing apparatus includes: a stage 2 capable of levitating and transporting a substrate 3 by jetting gas from a front surface; a laser oscillator configured to irradiate a laser beam 20a onto the substrate 3; and a gas jetting port arranged at a position overlapping a focus point position of the laser beam 20a in plan view, and being configured to jet inert gas. The front surface of the stage 2 is constituted by upper structures 5a and 5b, and the upper structures 5a and 5b are arranged so as to be spaced apart from each other and face each other. A gap between the upper structures 5a and 5b overlaps the focus point position of the laser beam 20a in plan view. A filling member 8 is arranged between the upper structures 5a and 5b so as to fill the gap between the upper structures 5a and 5b.

Abstract: A transferring device (100A) acquires address information indicating a network address of an upper network (N0) and a host address of the transferring device. The transferring device generates a subnet address which is a network address of a lower network (N1) by replacing a lower bit portion in the network address indicated in the address information with the host address indicated in the address information. The transferring device selects a host address to be assigned to a terminal device (220A) from a host address range which is based on the subnet address, and provides for the terminal device, address information indicating the subnet address and the selected host address.

Abstract: A communication apparatus includes a time-stamp generating unit for generating a time stamp during transmission or reception of a PDU transmitted and received, a transmission-data storing unit, a reception-data storing unit, a frame processing unit configured to generate a PDU including a data refresh instruction to the other node, periodical transmission data in the transmission-data storing unit, and a frame transmission time acquired from the time-stamp generating unit and store, upon receiving a PDU from the other node, periodical transmission data included in the PDU in the reception-data storing unit, and a one-way-delay detecting unit for determining, upon receiving the PDU, according to whether a next PDU has been received within a first delay allowable time after the last PDU was received, or whether a transmission time of the PDU is within a second delay allowable time, presence or absence of occurrence of a delay of a PDU.

Abstract: A system for delivering video data comprises a video server (1) including a video database (11) for storing video index information (13) defining a plurality of settings for a transfer bit rate of video data and indicating which data included in original video data (12) the video server should transfer to a client (2) through a network (3) when setting the transfer bit rate to one of the plurality of settings, a video data assembler (14) for extracting data from the original video data by referring to the video data index information so as to set the transfer bit rate to one of the plurality of settings, and for reassembling the extracted data to create video data to be transferred at the set transfer bit rate to the client, while maintaining consistency in contents of the original video data, and a video data delivery unit (15) for delivering a constant amount of data at certain intervals in accordance with the set transfer bit rate in order to transfer the video data reassembled by the video data assembler
