Patent EP-0333615-A3 (EP)
IPC: H04L29/06
Filed: 1989-01-31
Abstract: A method is disclosed for allowing two nodes (12, 14) in a 
communications network to dynamically establish the 
transmission group number used to partially identify a given 
link (18) between the nodes. When the link is being activated, 
both nodes simultanesouly propose either a zero or a non-zero 
number to each other in an exchange of exchange identification 
(XID) messages. If only one of the nodes proposed a non-zero 
number, that non-zero number is selected as the transmission 
group number. If both nodes had proposed zero or both had 
proposed non-zero numbers, predetermined criteria are employed 
to select a controlling node. The controlling node chooses the 
final transmission group number and communicates that choice to 
the non-controlling node.

IPC: H01L21/266
Filed: 1990-03-16
Abstract: A method of forming a well of one conductivity type in a silicon 
substrate, which method comprises the steps of:- 
   (a) providing a silicon substrate having a first surface region 
thereof which is doped with a dopant of one conductivity type and a 
second surface region thereof which is doped with a dopant of opposite 
conductivity type, the first and second regions being covered by 
respective first and second portions of an oxide layer which has been 
grown on the silicon substrate, the first portion being thicker than 
the second portion;    (b) oxidizing the substrate thereby to increase the thickness of 
the oxide layer such that the difference in thickness between the 
first and second portions is reduced;    (c) heating the substrate to cause diffusion of the said dopant 
of one conductivity type thereby to form a well of said one 
conductivity type in the substrate and also diffusion of the said 
dopant of opposite conductivity type down into the substrate, the 
heating step being carried out before, during or after oxidizing step 
(b); and    (d) removing the oxide layer thereby to expose the substrate 
surface which has a step in the region of the well boundary.

Title: Conveying rotational member for an ink recording apparatus
IPC: B65H27/00
Filed: 1990-09-17
Abstract: In a conveying member (8) for an ink recording apparatus which is used in a conveying system for a recording medium (P) in the ink recording apparatus for effecting recording by the use of ink and which bears against the surface of the recording medium after printing and is rotated, the peripheral surface (80) of the member (8) is of a shape in which it continuously bears against the recording medium (P), and the region of the member which contacts with the printing surface of the recording medium makes the bonding power with respect to the ink small relative to the sum total of the bonding power between the recording medium and the ink and the cohesive power of the ink itself, thereby preventing the adherence of the ink to the continuous peripheral surface (80).

Title: 2,5-dichlorophenylthioglycolic acid derivative and method for its production
IPC: C07C323/66
Filed: 1992-01-23
Abstract: The present invention is directed to novel 2,5-dichlorophenylthioglycolic 
acid derivative, a process for their 
production and a process for producing the desired product 
2,5-dichlorophenylthioglycolic acid derived from said novel 
compounds. 2,5-dichlorophenylthioglycolic acid derivative 
of the present invention can be obtained by reacting 
2,4,5-trichlorobenzensulfonates and thioglycolic acid in the 
presence of base, and said desired product can be obtained by 
desulfonating said compound in an aqueous solution of mineral 
acid. Novel 4-carboxymethylthio-2,5-dichlorobenzenesulfonates

intermediate for the production of 2,5-dichlorophenylthioglycolic 
acid. The use of said intermediate makes it possible 
to obtain the desired product in a decreased process steps 
with high yield. In addition, it poses no problem of 
environmental pollution as pointed out with conventional 
methods because it uses no heavy metals.

Title: Method of reducing wasted bus bandwidth in a computer system
IPC: G06F9/52
Filed: 1992-05-28
Abstract: In a multiprocessor computer system (10), wasted bus 
bandwidth resulting from slow responding slaves (S) is reduced 
by relinquishing the master (M) that was busied by the slow 
responding slave, and then causing the slave to effectively 
arbitrate for bus (12) control on the relinquished master's 
behalf when the slow responding slave is either available to 
service the master or has the requested data. In accordance 
with the disclosed embodiment, the slave effectively 
arbitrates (36) for bus control on the relinquished master's 
behalf by placing a unique arbitration code associated with 
the relinquished master on the bus. The relinquished master 
detects (42) the presence of its arbitration code and then 
again arbitrates (22) for bus control so that it may 
communicate with the slow responding slave.

Title: High-withstand voltage integrated circuit
Inventor: FIJIHIRA TATSUHIKO
IPC: H01L27/088
Filed: 1992-11-24
Abstract: In order to achieve cost reduction and improve the 
reliability of an IC integrating power element, together with a 
control circuit and protective circuit, power elements are controlled 
by a low potential circuit (L) depending on a low potential power 
source (VL), a high potential circuit (H) depending on a high 
potential power source (VH), and a medium potential circuit (M) 
depending on an output-stage voltage. As a result, the required 
number of high-withstand voltage elements is reduced, hence the size 
of a p-channel MOSFET (22) can be reduced, enabling a reduction in 
chip size and cost, and making it possible to obtain a constant main 
power source potential and voltage between the parts of the high 
potential circuit (H).

Title: Solvant for use in carbonless paper, comprising diisopropylmethylnaphthalene, and products utilising same.
Inventor: EARHART HAROLD W

Filed: 1993-08-24
Abstract: A carbonless paper solvent is provided comprising diisopropylmethylnaphthalene, generally in an amount of from 20% to 100% of the total weight of the solvent. The solvent is combined with a chromogenic substance and is encapsuled into microcapsules. The microcapsules are applied to a sheet of material and a color developing substance is then applied to another sheet to form a carbonless marking system. When the microcapsules are ruptured, the solubilized chromogenic substance contacts and reacts with the developer to form an image. In a method of the invention, a by-product fraction consisting of components with a boiling point range of 200 to 400 DEG C are contacted with propylene under conditions sufficient to form an alkylation product comprising diisopropylmethylnaphthalene.
