IPC: C09D11/38
Filed: 1998-05-26
Abstract: PROBLEM TO BE SOLVED: To obtain a recording ink having properly dispersed carbon black and excellent storage stability of ink, capable of stably providing an excellent image, by using improved carbon black as a colorant. SOLUTION: This ink is obtained by dispersing carbon black containing a functional group which is generated by the decomposition of a free radical generator composed of an azo group-containing polymer and is linked to the surface by chemical bond into a water-based medium (preferably water or a water-soluble organic solvent such as methyl alcohol, ethyl alcohol or the like). The free radical generator is preferably an azo group-containing polymer having a structure of formula I (R1 and R2 are each an alkylene; A is a group containing NH groups or O atoms at both ends). The polymer is decomposed and functional groups of formula II and formula III are generated and bonded to the surface of carbon black.  Consequently the mutual aggregation of the carbon black in the water-based medium can be prevented by the functional group bonded to the surface so that the clogging of a nozzle of a recording apparatus can be prevented.

Title: Flow control method, communication element for executing the same and communication terminal
Inventor: IKUSHIMA KIMIYA
IPC: H04L12/28
Filed: 1999-05-24
Abstract: PROBLEM TO BE SOLVED: To perform flow control capable of reducing a cell abandonment rate, even for the connection of a narrow band using an ABR service category and improving communication efficiency in an ATM communication network. SOLUTION: When a connection using ABR service in the ATM communication network is set, in this communication element 100, an ABR transmission band calculation part 106 calculates an ABR allocation band and a transmission band judgement part 108 decides whether or not the ABR allocation band is lower than 50 Mbps. As a result, when the ABR allocation band is lower than 50 Mbps, a PCR calculation part 112 calculates the value of RIF in the range of 1/4<=RIF1<=1 for instance, calculates the value of PCR in the range that the total value of PCR becomes 20%-60% of the ABR allocation band and defines that RDF is '1'. Based on the values decided in such a manner, a parameter setting part 3 sets the values of RIF, RDF and PCR which are ABR parameters.

Title: Heat-resistant and anticorrosive copper alloy for electric conduction
Inventor: KOMATA KENICHI
IPC: C22C9/00
Filed: 1980-10-15
Abstract: PURPOSE: To obtain a copper alloy for electric conduction excellent in heat resistance and anticorrosion, by incorporating a specified quantity of Ag into Cu.  
     CONSTITUTION: When 0.005W1wt% of Ag is added to Cu, the heat resistance and anticorrosion can be improved without lowering the electroconductivity of the Cu. The reason why the amount of Ag is at least 0.005wt% is that if the quantity is below 0.005wt%, the effect with respect to the heat resistance and anticorrosion has not been obserbed, and if the quantity is above 1wt% it would not be practical in view point of the cost. Further, in addition to Ag, if one or more of Mg, Al, Si, Mn, In and rare earth elements are added in a quantity up to 2wt%, the heat resistance and anticorrosion would be additionally improved. However if the quantity exceeds 2wt%, the conductivity is remakably lowered.

Filed: 1998-05-26
Abstract: PROBLEM TO BE SOLVED: To prevent the occurrence of cracks and the scattering of small glass fragments when a shock is applied by sticking an adhesive tape to at least four corner sections on a panel surface. SOLUTION: A shrinkage fit implosion-proof band 4 made of a frame-shaped metal band is fitted to the outside face of the panel 3 of a tube body 2 astride the mold match line, and an adhesive tape 5 is fitted over the whole periphery at the peripheral section of a panel surface 3a, i.e., at the peripheral section of an ineffective screen on the outside of an effective screen. The implosion- proof band 4 can be folded on the panel side into a double structure to obtain large fastening force, for example. When the adhesive tape 5 is stuck, the occurrence of cracks at corner sections by a shock is prevented. Even if cracks progressing at peripheral sections than the corner sections occur, the scattering of small glass fragments is prevented by the adhesive tape 5.  The crack occurrence range is suppressed small, the depth of cracks is made smaller, and implosion-proof reinforcement is ensured.

Abstract: PURPOSE:To make a temperature of air to be blown out of a heater core a state of being stabilized over the whole surface of this heater core by making a flow of cooling water at both high and low temperatures properly reversed by operating a passage control valve. CONSTITUTION:Cooling water passes through a first pipeline P1 from a cooling water discharge opening 20 and flows into a heater core 3, then it passes through a second pipeline P2, returning to an engine cooling water system from a cooling water feedback part 21. When reversible control is performed in this state intact, a flow of cooling water is altered by a spool valve 22, flowing into the heater core 3 after passing through the second pipeline P2 from the cooling water discharge opening 20, then it comes to be put back to the engine cooling water system E from the cooling water feedback part 21 in consequence, whereby the flow of the cooling water in the heater core 3 goes into reverse from the outset. In consequence, inclination of a temperature of air to be blown out of the heater core 3 is reversed to the outset, therefore variations in the temperature of the air being blown out are thus solved aright.
