摘要:
A digital video signal is transmitted via a communication system which can transmit digital data through an asynchronous communication line (ATM communication line) or the like and, at the same time, voice information for the working communication and information such as computer information are transmitted by using the communication system. The user of a first data transmitting apparatus sets up the character data etc. for communication on the terminal. The set character data is multiplexed in the predetermined transmission packet together with the audio and video data output from the VTR device and transmitted via an ATM communication line 2 to a second data transmitting apparatus. In the second data transmitting apparatus, the character data is demultiplexed from the transmission packet and displayed on for example the display device of the personal computer. In place of the character information, also voice information can be transmitted by a telephone set. In this way, the users of both data transmitting apparatuses transmit and receive the working communication information by using the communication line for transmitting the digital video signal.

A method of producing a single crystal by Czochralski method by contacting a seed crystal with a melt in a crucible, and then pulling it slowly to grow a single crystal ingot, wherein a pulling condition is controlled according to a cumulative time of use of a heater surrounding the crucible. The pulling conditions to be controlled may induce the relative position of the heater and the crucible, the number of rotations of the crucible, the number of rotations of the crystal, or an atmosphere pressure in the furnace and a gas volume of flowing. Also described is a method of producing a silicon single crystal by CZ method wherein a dispersion of impurity concentration in the crystal can be reduced, and a single crystal can be produced stably.

An imaging device includes a detector that repeatedly carries out a series of operation of generating an evaluation value to evaluate the degree of focusing of a position after driving of a lens toward one end part in the drive range of the lens, and detects the evaluation value of a position that is closer to the end part than the position of the evaluation value of the highest degree of focusing and is immediately adjacent or adjacent across a predetermined number of positions to the position of the evaluation value of the highest degree of focusing. The imaging device further includes a drive controller that makes the series of operation be repeatedly carried out toward the other end part in the drive range of the lens, and drives the lens to a position of a degree of focusing not smaller than the detected evaluation value.

There are provided a scalable method for mobility management applied to an IP-based network system including a plurality of routers and a plurality of servers, a part of which serve as a home routing manager (HRM), a part of which serve as local routing managers (LRM) for individual mobile nodes. The method at least comprises the steps of sending a first query about a routing address of a destination mobile node toward the HRM, based on an activation notification (AN) from an ingress access router (AR) of the plurality of routers, triggered by a source mobile mode, from an LRM receiving the activation notification; relaying the first query via one or more intermediate routing managers (IRM) closer to the HRM until the first query reaches the HRM; and in response to the first query, sending the routing address of the destination mobile node back to the ingress access router through the relay path from the HRM.

A method for detecting a diameter of a single crystal at the time of pulling the single crystal from a silicon melt contained in a crucible according to the Czochralski method, the method including at least: using two cameras placed equidistant from each other as a target diameter upon forming a straight-body portion of the single crystal and face both ends of the diameter of the single crystal in a growth point of the single crystal respectively, to separately capture both of the ends of the growth point of the single crystal from an outside of a furnace, the growth point being a contact point between the single crystal and a melt surface; and detecting the diameter of the single crystal on the basis of the captured images. As a result, diameter detection precision is improved.
