Patent number: 6734937Abstract: An ECB-type vertically aligned liquid crystal device includes liquid crystal molecules each having a negative dielectric anisotropy and polyimide films for homogeneous alignment. In a process for manufacturing the liquid crystal device, the liquid crystal molecules are vertically oriented by exposing the liquid crystal molecules to light from either or both sides of substrates of the liquid crystal device. In addition, an aligner used for exposure is equipped with a filter so as to cut light having wavelengths of 400 nm or less and 600 nm or more, so that light having a wavelength of 400 to 600 nm can be utilized In this liquid crystal device, the response time becomes faster when a voltage is applied between electrodes.Type: GrantFiled: January 25, 2001Date of Patent: May 11, 2004Assignee: International Business Machines CorporationInventors: Teruhiro Nakasogi, Tetsuya Nogami, Kohji Murayama

Patent number: 6721858Abstract: A method and system for the parallel implementation of protocol engines based on memory partitioning. The method comprises the steps of partitioning a shared memory space into multiple mon-overlapping regions; and for each of the regions, using a respective one protocol engine to handle references to the region, independently of the other protocol engines. Preferably, the memory is partitioned into the non-overlapping regions either by using address interleaving or by using address range registers to identify address ranges for said regions. Also, preferably the protocol engines operate independent of each other and handle accesses to the memory regions in parallel.Type: GrantFiled: August 24, 2000Date of Patent: April 13, 2004Assignee: International Business Machines CorporationInventors: Douglas J. Joseph, Maged M. Michael, Ashwini Nanda

Patent number: 6720982Abstract: The present invention invalidates the operator's input which interferes with the normal operation of an application. More particularly, a transparent window 110 is previously generated behind an application 120 for which an operator's misoperation can occur. And, upon the detection of a predetermined operation having occurred on the application 120, the operator's misoperation such as double clicking is invalidated by outputting the transparent window 110 in front of the application 120.Type: GrantFiled: January 7, 2000Date of Patent: April 13, 2004Assignee: International Business Machines CorporationInventor: Akira Sakaguchi

Patent number: 6711606Abstract: The present invention relates to a method of increasing the availability of an application executed by a computer system. More particularly, the invention relates to a method of increasing the availability of an application executed by one or more application clients and a multitude of application servers executing the same application. The fundamental teaching comprises a multi-casting step wherein an application client is requesting execution of an application service by sending an identical application service request to a collection of N out of M application servers with 1<N≦M in parallel. Within an application server, preceding the application service execution step, an “only-once” determination step is suggested, for determining whether an application service request must not be executed more than once without jeopardizing application consistency. For such a case the taught method provides “only-once” execution behavior.Type: GrantFiled: June 14, 1999Date of Patent: March 23, 2004Assignee: International Business Machines CorporationInventors: Frank Leymann, Dieter Roller

Patent number: 6665809Abstract: The basic idea comprised of the present invention is to decentralize the generation of time information without suffering from the cost disadvantages expectable due to use of prior art techniques necessary for synchronizing and correcting a plurality instead of only one or two of time suppliers caused by said decentralization. This is achieved by the approach not to readjust the oscillator(s), but, instead, to accept the inaccuracy of the physical device ‘oscillator’ but to measure its inaccuracy and to correct it with the aid of a continuos correction calculation which is advantageously done in a digital way under usage of ETS input information and system oscillator output information.Type: GrantFiled: May 17, 2000Date of Patent: December 16, 2003Assignee: International Business Machines CorporationInventors: Gottfried Andreas Goldrian, Thomas Anthony Gregg

Patent number: 6636279Abstract: A Thin Film Transistor (TFT) array substrate has a dummy signal line as a short circuit wiring for preventing a short circuit due to electrostatic breakdown between a signal line as an upper layer wiring and a gate line as a lower wiring. The dummy signal line is formed on an outer peripheral area of the TFT array substrate. This dummy signal line has a three-layer structure of a silicon lower layer, an Indium Tin Oxide (ITO) intermediate layer and an aluminum (Al) upper layer, enumerated from the lower layer. Although the silicon layer is formed as one consecutive wiring during formation thereof, the silicon layer is etched simultaneously with the Al layer when the Al layer is subjected to pattern forming, and is electrically disconnected between the gate lines. Since the dummy wiring is disconnected after its formation, a short circuit does not occur between the gate lines even in the case where the dummy wiring and two or more of the gate lines are short-circuited with each other.Type: GrantFiled: July 20, 2001Date of Patent: October 21, 2003Assignee: International Business Machines CorporationInventors: Shinji Takasugi, Hideo Iiyori

Patent number: 6633991Abstract: A system and method for observing the two clocking phase signals, finding a point in time when said signals have a phase coincidence which is good enough for fulfilling a phase difference requirement (e.g. 20 ps), and switching from one clock source to the other. The essential idea is not to compare the phases directly but to generate an auxiliary signal out of the two clock signals which is easier to handle in order to find that desired point in time and which reflects all desired properties of the time dependent phase shift between said clock signals. At a predetermined location in the cycle of both clock signals (e.g. its positive transition) a pulse is generated out of each of the clock signals with matched identical delay elements located very close to each other on the same chip for both signals. As they match they produce exactly the same pulse widths. The absolute length of the pulse width is of minor relevance as long as the length of the pulses is the same within close limits.Type: GrantFiled: May 17, 2000Date of Patent: October 14, 2003Assignee: International Business Machines CorporationInventor: Gottfried Andreas Goldrian
