摘要:
A method of changing a fragment size of data packets in a router where a data packet is divided into the data packets having the fragment size, and are transmitted to a network along with audio packets includes the steps of acquiring, in the router, a parameter indicative of whether proper audio quality is maintained through transmission of the audio packets, and changing the fragment size of the data packets in response to the acquired parameter.

A mineral-water supplying apparatus includes: a mineral-water producing apparatus for producing mineral water by passing raw water, such as city water, through a mineral eluting material(s); a drink conveying pipe for conveying the mineral water produced in the mineral-water producing apparatus to a drinking water spout; a cleaning water pipe diverging from the drink conveying pipe for conveying mineral water to a nozzle; a pump for forcing the mineral water produced in the mineral-water producing apparatus to flow through the drink conveying pipe and the cleaning water pipe; and a chlorine generator for increasing the concentration of chlorine in the mineral water produced in the mineral-water producing apparatus. This allows chlorine to be added to the resulting mineral water and increases the concentration of chlorine in the mineral water.

A multimedia communications apparatus allows a multimedia personal computer to freely select a unit with which to communicate, so that the circuit usage efficiency of a network connected to the multimedia communications apparatus will be increased. The multimedia communications apparatus has a packet generator/separator, a packet type detector, a controller, and a table. The table stores data representing the correspondence between addresses of interfaces of the multimedia personal computer and AV devices and addresses thereof on the network. For communications, the controller refers to the table to establish logic paths from a unit with which to communicate and a transmission range depending on multimedia such as moving-image data, sound data, or the like to be transmitted, and rewrites the headers of packets based on the established logic paths. The packet type detector captures empty packets required for each session of communications, and the packet generator/separator updates a destination unit address, inserts multimedia information, and transmits the packets to the destination unit address. Upon completion of the transmission, the packet generator/separator releases the packets from the dedicated state.
摘要:
A communications system between LANs of different types constituted of a backbone LAN (1) and a plurality of branch LANs (7, 7') connected to said backbone LAN (1) through a node (2A, 2B, 2C, 2D). A branch LAN frame (30) delivered from a terminal (8, 9, 10, 15, 18, 21) is incorporated into a backbone LAN frame (40) in the node (2A, 2B, 2C, 2D), and in response to the incorporation, the address of the adjoining node on the downstream side of its own node is given to the backbone LAN frame (40), and thus, the backbone LAN frame (40) is transmitted through the backbone LAN (1). Each node (2A, 2B, 2C, 2D), when the address in the backbone LAN frame (40) agrees with its own address, separates the branch LAN frame (30) from the backbone LAN frame (40).
摘要:
In a water purifying apparatus (1) having inner and outer cylindrical electrodes (51,52) concentrically arranged together to form a water channel (500) therebetween, the outer electrode has a plurality of small perforations (55) penetrating therethrough. The electrodes are placed in a water tank (2) reserving raw water. A voltage is applied between the electrodes for causing electrolysis of the raw water in the water channel. As a result of the electrolysis, the raw water is processed into purified water. Resultant gases generated by the electrolysis may be released from the water channel through the small perforations of the electrodes. In addition, the inner electrode may have small perforations penetrating therethrough.
摘要:
In a water purification system in which a first filter (20) is placed in a flow of raw water for filtering the raw water to produce filtered water, a second filter (27) is placed downstream of the first filter for filtering the filtered water. The first filter is conductive and has a plurality of water passages through which the raw water flows. Each of the water passages of the first filter has a first diameter. At intervals, an electric voltage is applied to the first filter to destroy bacteria which is captured by the first filter. The second filter has a plurality of water passages through which the filtered water flows. Each of the water passages of the second filter has a second diameter smaller than the first diameter.
摘要:
In a water purification system for purifying raw water with a first d.c. voltage is applied between a conductive adsorber portion (20) and a primary electrode (27) in the raw water, a second d.c. voltage higher than the first d.c. voltage is applied in place of the first d.c. voltage at intervals between the adsorber portion and the primary electrode to accelerate generation of chlorine from the raw water. The primary electrode is opposite to the adsorber portion with a particular space left therebetween. It is preferable that the adsorber portion is provided with a supplementary electrode (29) which is opposite to the primary electrode so that the particular space is left therebetween.
