摘要:
A flow control device constructed at a switch device for connecting a plurality of ring networks for exchanging data of a cell among the ring networks. A user device for transmitting a cell carrying data is connected to each ring network, and it can transmit cells within a window counter number. Such flow control device comprises a buffer monitoring unit for monitoring the number of data in an output buffer, a regulation judging unit for comparing the number of data in each buffer with a first threshold value representing state of the buffer which is in danger of overflow, with a second threshold value representing state of the buffer which is not in danger of overflow, and outputting a regulation notice when the data number is grater than the first threshold value while outputting a regulation notice when the data number is smaller than the second threshold value, and a plurality of traffic controlling units for transmitting to the respective ring network a reset cell at a first interval when no regulation notice is received or the release notice is received while transmitting a reset cell at a second interval which is longer than the first interval when the regulation notice is received.

A packet communications network for transmitting data between nodes by the use of cell slots circulating the network includes a center node inserted in the ring network for sequentially generating, at a selected rate, first and second types of cell slots interleavingly for transmitting first and second types of data, respectively. Each cell slot has a type code for identifying either one of the first and second types, and a status code for identifying the different status of the cells. Each node detects whether the received cell is the first type or the second type. If the received cell is the first type, it is used for transmitting the connection-oriented data under MARS system. If the received cell is the second type, it is used for transmitting the connectionless data under ATMR system.

Disclosed is a data transmission unit for use in a system wherein data to be transmitted is organized into packets which may be assigned one of four states: idle, occupied, released, or reset. Or these packets may be assigned one of three states: idle, occupied, or released, each state being able to include a reset bit. Each unit has terminals associated therewith and is assigned two windows on the number of packets it may transmit. One window is a parameter for transmitting data by using idle packets and the other is by using released packets. The unit responds to the state of a received packet, the state of the windows, and the presence or absence of transmit data to control whether the packet transmitted out of the unit is a packet from internal transforming buffers, a released packet from a released cell producing circuit, an occupied packet containing data from the unit's own terminals. A released packet contains the address of the unit which generated it and is generated when there is no data to be transmitted and an idle packet is received by the unit. Any unit can occupy a released packet with data from its terminal within the second window band, thereby increasing data throughput.

Disclosed is a water-repellent/oil-repellent agent which is composed of a fluorine-containing polymer containing a repeating unit (A) derived from a fluorine-containing monomer having a fluoroalkyl group or a fluoroalkenyl group, and a repeating unit (B) derived from a monomer having an imide group at a weight ratio of from 10/90 to 95/5 (repeating unit (A)/repeating unit (B)). Also disclosed is a thermoplastic resin composition which is obtained by adding such a water-repellent/oil-repellent agent into a thermoplastic resin. Since the fluorine-containing polymer is improved in heat resistance, the water-repellent/oil-repellent agent is capable of imparting a wide range of thermoplastic resins with excellent water repellency and oil repellency.

An electronic component housing package includes a base body made of a metal; a rectangular frame body made of a metal; an input/output terminal made of insulating material, which has line conductor for electrically conductively connecting the interior and exterior of the frame body; and an input/output terminal mounting portion, into which input/output terminal is fitted and which is formed as a notch extending across two adjacent corners of a frame body's lower part. The input/output terminal is so configured that its opposed end-face pair at two corners are made flush with opposed outer-side-surface pair including two corners of frame body, and that metal layer is applied to both of a part of an input/output terminal's end-face extending along the mounting portion and another part thereof extending along the base body.

The present invention sets an auto-zooming frame that includes a plurality of selected subjects from among subjects detected from a captured image. Then, the angle of view is adjusted so that the entire auto-zooming frame is captured. Auto-zooming frame setting and angle of view adjustment are continuously performed on images that are consecutively captured, thereby providing auto-zooming control for a plurality of subjects.

Disclosed is a fluorine-containing polymer prepared by polymerizing (I) a polyfluoroalkyl group-containing (meth)acrylate which is substituted at alpha-position, in the presence of (II) a blocked isocyanate compound. A water- and oil-repellent composition containing the fluorine-containing polymer can impart the excellent water- and oil-repellency, and excellent durability thereof to substrates.

摘要:
Disclosed is a method for producing a fluorine-containing copolymer composition wherein a fluorine-containing copolymer is produced by polymerizing 1-99 weight % of a monomer mixture (A) containing a polymerizable monomer having a fluoroalkyl group and a polymerizable monomer having a hydrophilic group in the presence of 1-99 weight % of a surfactant (B) containing a surfactant having an oxyalkylene group. The total amount of the monomer mixture (A) and the surfactant (B) is not less than 80 weight % of the polymerization system.
