Abstract: In an LCD, according to an embodiment of the present invention, a projection 6 is structured on top of insulation layer 8 on a TFT glass substrate 10 and under part of a black matrix 9. The projection 6 encircles the transparent region in each pixel so that a spacer 17 cannot climb over the projection 6 and enter the transparent region even though a certain pressure is applied onto the substrates 10 and 11. The width of the projection 6 is equal to or less than the diameter of the spacer 17. The height of the projection 6 is equal to or longer than approximately 1% the length of the diameter of the spacer 17, and it is preferable that it be equal to or longer than approximately 2%.

Title: Plasma display panel
Inventor: AOKI MASAKI
IPC: H01J11/36
Filed: 2000-04-27
Granted: 2001-11-01
Abstract: The present invention provides a plasma display panel in which a space between a first plate and a second plate facing each other is filled with a discharge gas, a plurality of pairs of display electrodes made of Ag or Cu are formed on a surface of the first plate facing the second plate, and the surface is covered with a dielectric layer covering the display electrodes, where the dielectric layer is made of a glass that contains at least ZnO and 10 wt% or less of R2O and does not substantially contain PbO and Bi2O3, and a product of permittivity ε and loss factor tanδ of the dielectric layer is 0.12 or less, where R is selected from a group consisting of Li, Na, K, Rb, Cs, Cu, and Ag. The plasma display panel effectively prevents display performance from deteriorating by suppressing deposition of colloidal particles of Ag and Cu out of the display electrodes into the dielectric layer. The plasma display panel consumes a small amount of power since the product of permittivity ε and loss factor tanδ of the dielectric layer is lower than conventional ones. Also, the manufacturing cost of the plasma display panel is reduced due to reduction in the cost for baking the dielectric layer or the like which is achieved since the softening point of the glass with the above composition is 600 DEG C or less, lower than conventional ones.

Title: Substrate carrying device, processing device, processing system for substrate, conveying method, accommodating device and accommodating container
Inventor: OTA YOSHIHARU
IPC: H01L21/00
Filed: 2000-06-16
Granted: 2001-10-11
Abstract: The present invention is to support the glass substrate to be processed in the interior of box-type accommodating container; and, using the fan to form the air flow from the surface opposing to the forming face of the entry of the substrate to the outside through the substrate entry. Therefore the dust particle floating outside the accommodating container will not fall into the container even the substrate entry is open frequently. So, the conveying zone of the glass substrate will not need to be the dustless environment that can greatly reduce the cost for establishing the dustless environment. Because the substrate entry is open frequently, there will be no open/close mechanism for opening/closing the substrate entry so as to exchange the substrate more rapidly further.

Title: Circuit and method for generating a synchronous clock signal
Inventor: CHANG JEFF
IPC: H03K7/08
Filed: 2000-06-19
Granted: 2002-03-01
Abstract: A method for generating a synchronous clock signal and a circuit (10) for implementing the method are described. To generate the positive-going transition of the clock signal, the method generates a synchronization pulse train using a synchronization signal input. The method generates a second pulse train, having pulses offset in time from and later than those of the synchronization pulse train, to generate the negative-going transition of the clock signal. The duty cycle of the synchronous clock signal is nearly equal to the duty cycle of an asynchronous clock signal which can be generated in the absence of the synchronization signal input. Because there is little loss in duty cycle, when the synchronous clock signal is input to a power factor correction (""PFC"") and pulse width modulation (""PWM"") controller circuit, the PFC and PWM controller is able to operate normally.

Title: Impact method and the device used in downhole standard penetration test
Inventor: TSAI JIN-SUNG
IPC: G01N1/14
Filed: 2000-12-30
Granted: 2002-11-01
Abstract: Disclosed is an impact method and the device used in downhole standard penetration test that can be performed in deep ground and deep water. The standard penetration device enclosed watertight by round caisson. Inside the caisson, the hammer directly strikes the sampler's top anvil to avoid the impact energy loss that occurs in a traditional standard penetration test that strikes the top of a long drill pipe on the ground surface and transmits the impact energy to the sampler through the long drill pipe. Using this method, there is no need to assemble long drill pipes. Therefore, the impact energy can be transmitted stably to the sampler and an accurate relationship between standard penetration energy and N value can be obtained.

Title: Apparatus and method for recovering a failed database data set
Inventor: MOORE DAVID W
IPC: G06F11/14
Filed: 2001-02-07
Granted: 2003-03-01
Abstract: The present invention is a recovery utility apparatus for expediting recovery time during failure of one or more database data sets. A backup copy restore utility reads one or more backup copies of the database data sets in parallel. Simultaneously, a change accumulation manager reads one or more CADSs in parallel. Each CADSs associated with one or more database data sets requiring recovery is only read once into memory. In this manner, parallel execution of the read process reduces recovery time. To further expedite recovery, as the backup copy is written to the restored database, records from the CADS are merged with the restored database as they are needed and as they become available. The change accumulation manager reads only the detail records which have been committed and ignores the spill records to eliminate the need for completing each incomplete CADS for recovery. A log manager reads one or more logs to derive the updates in the spill records which are subsequent to a merge end point. Reading the logs confirms which updates in the spill records have been committed and may be merged with the restored database. The logs are read in parallel to reduce read time and are merged with the restored database before the read process is complete.
