摘要:
Polymers comprising a polymer backbone having pendant or terminal betadiketone groups which contain at least one trifluoromethyl group. The betadiketone groups may be selected from trifluorocetoacetate groups (general formula I); ##STR1## hexafluoroacetylacetone groups (general formula II); ##STR2## or trifluoro-2,4-pentanedione groups (general formula III); ##STR3## where indicates the polymer backbone, R is an alkyl, substituted alkyl, aryl or substituted aryl group and R.sup.1 is hydrogen, alkyl or substituted alkyl. Neither the R group nor the R.sup.1 group should contain any group which is sufficiently basic to initiate cyanoacrylate polymerization or any group sufficiently acidic to interfere with chain transfer.
摘要:
Cationically polymerizable styryloxy resins having urethane linkages, represented by the formula III ##STR1## wherein R.sup.1 and R.sup.2 are H, or one of R.sup.1 and R.sup.2 is H and the other is methyl;R.sup.3 and R.sup.4 (which may be the same or different) are H, lower alkyl, or alkoxy if R.sup.2 is not methyl;R.sup.5 is a divalent hydrocarbon radical;G.sup.1 is an n-valent hydrocarbon radical free of amino, aliphatic thiol, aliphatic hydroxyl or other groups which interfere with cationic polymerization;and n is an integer of 2 or more.G.sup.1 is a hydrocarbon backbone which is not interrupted by a hetero atom. Preferably G.sup.1 is a residue of a diene homopolymer or copolymer, in which case the resins produce flexible polymers. The resins are polymerized with a cationic polymerization initiator or latent acid catalyst. The resins have utility in the field of electronics.

Polyfunctional cationically polymerizable styryloxy compound of the formula ##STR1## where R.sup.1 and R.sup.2 are H, or one of R.sup.1 and R.sup.2 are H and the other is methyl; R.sup.3 and R.sup.4 are H, lower alkyl, or alkoxy if R.sup.2 is not methyl; R.sup.5 is a divalent hydrocarbon radical; G is any multivalent organic or inorganic radical free of amino, aliphatic hydroxyl, aliphatic thiol or other groups which interfere with cationic polymerization; and n is an integer of two or more.
摘要:
A method of developing or improving a parts inspection process, the method comprising: selecting at least one target part for inspection; convening a panel to review samples of the target part, and to define conditions and determine a disposition of the target part samples; conducting initial inspections of the target part samples to obtain sample inspection results; comparing the sample inspection results with the conditions and disposition of the target part samples set by the panel; determining a cause of variability between the sample inspection results and the conditions and disposition of the target part samples set by the panel and generating one or more solutions for the cause of variability; creating an inspection standard based on the one or more solutions; conducting training of inspectors using the inspection standard, with inspectors which qualify on the training proceeding with routine inspections; and conducting reviews of the routine inspections to determine an inspection error rate; wherein the routine inspections are allowed to continue if an acceptable inspection error rate is achieved, and wherein an inspection standard review is performed if an unacceptable inspection error rate is achieved.
摘要:
A system and method for transmitting messages from a client messaging application to a third party application is shown. The method includes registering with a set of client messaging applications for sending and receiving messages. A message includes an information request. A message is received from the one of the client messaging applications and the destination of the message is determined. The third party application determined to be the destination of the message is then selected and the message is transmitted to the third party application. In the event that the message included an information request, a return message is received from the third party application. The return message includes the requested information. The destination of the return message is determined. The client messaging application determined to be the destination of the return message is selected and the return message is transmitted to the client messaging application.
摘要:
A peer-to-peer network propagates searches from client to client. Resources within each client are selectively searched in response to authentication and authorization processes. Authentication information may be included in a search request or may be performed by an authentication process external to the client. Authorization is performed by a process external to the client. Only after authentication or authorization may resources of any particular client be accessed. The system allows for secure propagated searches and resource access in a peer-to-peer network environment. The network may further include a server for maintaining a list of clients connected to the peer-to-peer network in order to more efficiently facilitate peer-to-peer communications.
