Around a damaged area of a jacket of a flexible tube, a top coat layer whose adhesion to a polymer layer is weak is peeled off with an adhesive tape. The damaged area and its immediate surrounding area are sanded, and then wiped with ethanol for cleaning. A main agent and a hardening agent are heated and defoamed while being mixed to prepare a repair material. The repair material is applied to the damaged area and the immediate surrounding area. A heat shrink tube is opened along slits in an end portion and covers the flexible tube. The heat shrink tube is shrunk with hot air, pressing the repair material and making it flush with a surface of the jacket. The flexible tube is heated with an electric hot plate to harden the repair material. Thereafter, the heat shrink tube is peeled off from the flexible tube.

A mobile communication system 100 according to the present invention comprises handover control apparatus 1 and radio terminal unit 10. The handover control apparatus 1 controls handover of a radio terminal unit 10 between access routers 31-34 provided in respective base stations 21-24 for radio communication with the radio terminal unit 10. The handover control apparatus 1 counts the number of relay routers for every candidate access router 32-34 for a destination of the radio terminal unit 10, from a gateway device 52 and determines a COR on the basis of the number of relay routers for every access router 32, 33, 34 thus counted.

To prevent jamming with small-sized print materials without disturbing an image located at a trailing end of a print material, an image forming apparatus includes a photosensitive drum that carries a toner image, a transfer device which can apply a transfer bias to the transfer roller to transfer the toner image to a print material passing through the transfer nip portion, and a control device for controlling a transfer bias set value set in order to apply a predetermined transfer bias to the transfer roller. The control device switches a first transfer bias set value to a second bias set value smaller than the first transfer bias set value while the print material is passing through the transfer nip portion, in order to change the transfer bias applied to the transfer roller.

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.

A device for pulling a silicon single crystal is constructed so as to preclude deposition of a SiO-derived substance on graphite parts inside the device and prevent the graphite parts from deterioration, elongate the duration of continuous use of the device in a great measure, and simplify the disassembly and reassembly of the device.This device pulls a silicon single crystal in an atmosphere of inert gas by the Czochralski method, which device is chracterized by comprising a crucible 1 for accommodating a molten silicon mass 2, a heater 3 disposed round the periphery of the crucible 1, an outer member 14 forming a pulling chamber 6 for accomodating the crucible 1, an inert gas inlet part 15 disposed in the upper part of the pulling chamber 6, and an inert gas outlet part 16 separated from the inert gas inlet part 15 in the same upper part of the pulling chamber 6.
摘要:
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.
摘要:
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.
