Title: Method for producing saponified ethylene-vinyl acetate copolymer
Inventor: KAWAHARA TAKAHARU
IPC: C08F216/06
Filed: 2001-06-29
Granted: 2004-06-02
Abstract: This invention provides a method for producing a saponified ethylene-vinyl acetate copolymer in which visible imperfections (particularly fish eyes) of the saponified copolymer is inhibited. In this invention, a mixture solution is prepared by adding water to a methanol solution after saponifying an ethylene-vinyl acetate copolymer, and insoluble materials are removed from this mixture solution. Various types of filter or centrifugal separator are used to remove insoluble materials. It is preferable that the weight ratio of methanol to water is from 5 : 5 to 9 : 1, the concentration of the saponified copolymer is from 30 to 60 wt %, and the temperature is from 55 to 80  DEG C. This method is particularly suitable for producing a saponified ethylene-vinyl acetate copolymer having an ethylene content of 20 to 70 mol % and a saponification degree of at least 95 mol %.

Filed: 2004-02-11
Granted: 2005-05-18
Abstract: A PPPoE (Point-to-Point Protocol over Ethernet) network system and connection method thereof. The connection method includes the steps of: if a connection attempt is made, transmitting a PADI (PPPoE Active Discovery Initiation) packet to a plurality of servers by performing a discovery stage; after transmitting the PADI packet, deciding whether a packet being transmitted from a server is transmitted in a session packet in a PPP session stage or a PADO (PPPoE Active Discovery Offer) packet; and if the packet being transmitted from the server is the session packet, terminating connection between a client and an already-connected server by performing a discovery stage for terminating the connection, and then reestablishing the connection by performing a discovery stage for connection. Therefore, even though the connection between the client and the server is unproperly disconnected due to errors on the client side, the connection can be reestablished faster and more effectively.

Title: Improvements in and relating to methods of testing integrated circuits
Inventor: BRADFORD JONATHAN
IPC: G01R31/3185
Filed: 1988-07-21
Granted: 1992-09-30
Abstract: To test an integrated circuit such as in Fig 1 wherein there are different paths with different delays between input test registers R1, R2 and output test registers R3, the different delays preventing exhaustive test patterns from being applied to internal embedded combinational blocks Ca, Cb, the serial path of shift registers has additional registers Ds(Fig 2) to resynchronise the test patterns for the logic blocks. Alternatively, the serial path is considered to have imaginary delays present and non-contiguous inputs to the logic blocks are stimulated by exhaustive test patterns provided by a special algorithm viz a polynomial functionally dependent on the difference in the delays along the signal paths. The technique may be used with interleaved test registers. <IMAGE>

Title: Active clearance control for gas turbine engine
Inventor: WALKER ROGER CLAYTON
IPC: F02C7/28
Filed: 1989-03-31
Granted: 1992-08-19
Abstract: The invention concerns an active clearance control for controlling clearance between a turbine and a casing in a gas turbine aircraft engine. The invention calculates the instantaneous clearance between a turbine casing and a turbine rotor, based on temperature. Two temperatures are involved. First, a steady state temperature (SSTemp) is computed for the rotor and the casing. SSTemp is a predicted, future temperature, which will be attained when the engine reaches steady state operation. Each SSTemp is computed based on presently occurring engine operating conditions, such as selected temperatures, pressures, and rotational speeds. Changes which occur in the SSTemp's indicate the second temperatures, which are the instantaneous temperatures of the casing and rotor. These changes in SSTemp are caused by changes in the present operating conditions, which occur during engine acceleration and deceleration. The instantaneous temperatures indicate the diameters of the casing and the rotor, and thus the instantaneous clearance between them. In another form of the invention, the computed instantaneous clearance is used to control air which is bled from the fan and ducted onto the casing, in order to attain a desired clearance.

Title: Light emitting diode assembly
Inventor: PYE JOHN ALBERT
IPC: G01N21/27
Filed: 1991-10-22
Granted: 1996-02-21
Abstract: A light emitting diode (LED) 20 is mounted on the surface of a header 42 and a photodiode 41 is mounted on an orthogonal extension 43 of the header such that some of the light emitted by the LED 20 falls directly on the photodiode without having undergone reflection from other surfaces. The photodiode is used to sense the output intensity of the LED. The direct optical path between LED and sensor means that the photodiode output is insensitive to movement between the assembly and its surroundings, which movement can give rise to errors in prior art arrangements involving reflection from a further surface. The assembly may be used in an exhaust gas sensor in conjunction with a further photodiode. <IMAGE>

Title: Message searching system and terminal
Inventor: ITAKURA YUICHIRO
IPC: G06F17/30
Filed: 1997-05-08
Granted: 2000-08-09
Abstract: A message searching and system and a terminal, which display messages to terminal users based on their individual characteristics profile, even when a plurality of users use the same terminal and even when users copy and use the same program. The system includes a message user database for storing records defining user characteristics profiles of terminal users, and a transmittal condition database for storing searching conditions for each message which may be transmitted to the terminal. This system detects a necessity to revise the user characteristics when communicating with the terminal, and revises the user characteristics if necessary. This system reads user characteristics from the message user database, and searches for appropriate messages from the transmittal condition database based on the user characteristics and characteristics associated with each message identifier. The message user database stores each user's birth date and the last system communication date. The user's characteristics profile is updated based on various conditions. For example, if the date obtained by adding a predetermined period to the user's birth date is after the last communication date with the user, the characteristics profile is revised.
