The record of changes in the size of a workpiece, which is measured by a gage head during grinding, is graphed on a color LCD of a control part. It is therefore possible to know if there is an abrupt change or no change in the size of the workpiece during the grinding just by looking at the graph. Thus, the sharpness of a grinding wheel can easily be judged during the grinding.

An HDD, to which servo data is written, is fixed on a base. As an upper base moves, a both-end supporting mechanism provided on the upper base approaches a rotation shaft which supports a disk. When the both-end supporting mechanism is brought into full contact with the tip portion of the free end of the rotation shaft, a process of writing servo data is carried out on the disk. While writing the servo data, the rotation shaft is maintained in the both-end supported state, and therefore a non-repeatable vibration of the rotation shaft caused by a rotation of a spindle motor is suppressed. After the servo data writing process, the both-end supporting mechanism is withdrawn from the rotation shaft as the upper base moves.

A loading/ejecting device for loading and ejecting a floppy disk into and from a magnetic disk drive apparatus has a holder for containing the disk therein. The holder is supported by a pair of guide plates to be movable directly between a first position where the disk can be inserted into or ejected from the holder and a second position where the disk can be reproduced or recorded. A loading/ejecting member is supported by the guide plates to be movable between an initial position and a forward position. The member is urged by tension springs toward the forward position and is latch by a latching member in the initial position. When the disk is inserted into the holder, a urging member supported on the holder is moved by the disk to push the latching member, thereby disengaging the latching member from the loading/ejecting member. As a result, the loading/ejecting member is moved from the initial position to the forward position, thereby moving the holder from the first position to the second position. A hold plate is mounted on the holder and locks the disk in a predetermined position in the holder when the disk is inserted into the holder. The loading/ejecting member has an urging arm. When the loading/ejecting member is moved from the forward position to the initial position, the holder is moved from the second position to the first position by the member and the hold plate is urged by the urging arm to release the locked state of the disk.

A translation apparatus retains a first correlation between a Mobile IPv6 terminal's home address and virtual IPv4 address. When the Mobile IPv6 terminal transmits a packet to said IPv6 network with a care-of address specified as the packet's source address and a home address specified in an extension header, the translation apparatus changes the packet's source address to a virtual IPv4 address that corresponds to the packet's home address in accordance with the first correlation, and then transmits the packet to an IPv4 network. Mobile IPv6 terminal-to-IPv4 terminal communication can then be established between an IPv6 network to which Mobile IPv6 terminals are connected and an IPv4 network to which IPv4 terminals are connected.

A method of relaying data between a first terminal device connected to a first network and a second terminal device connected to a second network comprises: searching in a storing device based on location information accompanying data received from the first terminal device or the second terminal device, the storing device storing location information indicative of a location of at least the first terminal device; as a result of the searching, if the location information exists in the storing device, converting the location information accompanying the data so that the location information stored in the storing device becomes a new location information of the data; and sending the data accompanied with the location information having been converted to the second terminal device or the first terminal device.

A plurality of packet gate ways (PGWS) are connected between a mobile communication system and an internet so that the corresponding IP subnetworks to those PGWs may be built. A visitor location register (VLR) operates to notify the PGW of location information of the mobile station (MS) and an IP address of a data terminal connected with the MS. If the notified IP address belongs to another IP subnetwork, the PGW notifies the corresponding PGW to that IP subnetwork of a fact that the local PGW is a destination. The PGW operates to manage the location information of the MS connected with the data terminal based on the notified content and perform the packet routing based on the managed content.

The invention provides a fluorescent lamp for plant growth capable of controlling morphology in terms of grass height, area and shape of leaves and so forth, approximating those obtained under natural daylight, while effectively promoting photosynthesis of the plant. The fluorescent lamp has a glass tube and a fluorescent layer formed on the inner surface of the tube and composed of four fluorescent components having light emission peaks in the bands of 440 to 460 nm, 540 to 560 nm, 600 to 620 nm and 700 to 800 nm, respectively, said fluorescent layer having the PF ratio ranging from 0.8 to 1.2 in terms of the ratio between the photon flux PF contained in the wavelength band of 600 to 700 nm to that in the wavelength zone of 700 to 800 nm. According to the invention, the spectral characteristic of the fluorescent lamp is so selected that light in the wavelength band of 700 to 800 nm, which influences the morphology of the plant and elongation of the plant, in addition to the light in the wavelength band of 400 to 700 nm, which is effective in photosynthesis, is applied to the plant so as to attain growth substantially equivalent to that obtained under the natural light.

In a shared-buffer-type ATM switch including a multiplexer, a shared buffer memory, a demultiplexer, a buffer memory controller, a cell copy section is disposed between the multiplexer and the memory. The copy section produces a plurality of copies of a broadcast cell according to information of a copy information table and adds associate routing information to each copied cell so as to write the cells in the memory. In response to an indication from an output counter, the cells are read from the memory to be distributed to output ports, thereby implementing a broadcast function.

A discharge lamp which radiates visible light having the following lights combined: light having an emission peak in 400 to 490 nm wavelength range in a blue spectral region; light having an emission peak in a 500 to 550 nm wavelength range in a green spectral region; and light having an emission peak in 600 to 670 nm wavelength range in a red spectral region.

摘要:
An IPv6 mobile packet communication network in which mobile VPN service can be provided without having to use a mobile tunnel. A control signal for enabling packet data transmission and reception is sent from a mobile terminal to a gateway node. Using destination-of-connection information contained in the control signal, the gateway node checks whether mobile VPN service is requested or not. Upon detection of a mobile VPN service request, the gateway node returns IP address information of the gateway node to the mobile terminal via a subscriber node. The mobile terminal then assembles an IPv6 header (210) and an IPv6 routing header (220) so that packet data will be unexceptionally transferred through the gateway node.
