Filed: 1999-10-26
Granted: 2001-09-01
Abstract: This invention introduces an image correction method, an image correction device, and a CRT display device to lower the consumed power required to correct images during a long period of use time. After microcomputer 2 provides power source to the CRT, it commands the corrected current to decrease monotonously as time passes to calculate the value of the corrected current. Drivers 3 to 7, 22 generate corrected output currents based on the values of the corrected currents calculated by the microcomputer 2. The correction device C assembled at the CRT receives the corrected currents from the drivers 3 to 7, 22 and then corrects the displayed image on the CRT.

Title: Device to eliminate DC offset of tracking error signal for optical read/write pickup heads
Inventor: WANG JINN-KANG
IPC: G11B7/00
Filed: 1999-12-27
Granted: 2001-09-21
Abstract: A device to eliminate DC offset of for optical read/write pickup heads is disclosed. The device uses a holographic optical element (HOE) to separate the return beam reflected from optical disc directly to 0 order diffraction beam, which generates focus error signal, and +1 and -1 order diffraction beams, which generate tracking error signal, in a single return beam path. The 0 order diffraction beam is focused on a quadrant photodetector and converted to a first electrical signal. The +1 and -1 order diffraction beams are focused on a first tracking sensor array and a second first tracking sensor array and converted to a second and a third electrical signal. Processing the first electrical signal in a focus error signal generating circuit and the second and third electrical signal in a tracking error signal generating circuit produces focus error signal and tracking error signal respectively. By using this technique, spot asymmetry due to aberration of return beam can be corrected.

Title: Selective and efficient messaging in a mobile communications system
Inventor: TELLINGER JAN
IPC: H04Q7/22
Filed: 1999-12-10
Granted: 2001-10-01
Abstract: A selective messaging procedure efficiently distributes messages only to eligible cells and eliminates distribution of unnecessary messaging information to ineligible cells in a mobile communications network. When information is received in the network that is intended for a mobile station located in an area containing one or more cells, the admission status associated with each of the cells in that area is determined. A message is then sent to one or more of the plural cells whose associated admission status is determined to be favorable. On the other hand, that message is not sent to any cell having an unfavorable admission status. In order to keep track of cell admission status, a list data structure is established in memory for each area and may include, for example, an admission indicator for each listed cell. Based on one or more admission criteria, an appropriate value may be stored for each admission indicator in the list. When a message for the mobile station is detected, and the area in which that mobile station is currently registered is determined, a decision is made whether to send that message to one or more cells in the area depending on the admission indicator value for the one or more cells in that area. An alternative cell list structure adds a cell to the list if the condition is met, and removes a cell from the list if the condition is not met. The admission status of each cell is regularly monitored and updated.

Abstract: Photoelectric conversion chips having the same structure are disposed in line and electrically connected together to constitute a multi-chip type image sensor. The gate of a load transistor of a source follower circuit of each of the photoelectric conversion chips is connected in common to one constant current source circuit. The constant current source circuit and photoelectric conversion chips are mounted on a substrate. With this structure, the common current source circuit is used for all the source follower circuits so that noises will not be generated on the photoelectric conversion chip unit basis. The multi-chip type image sensor can therefore improve the image quality, and horizontal or vertical stripes to be caused by noises otherwise generated in separate constant current source circuits can be removed.

Abstract: The present invention is an apparatus for performing heat and cooling treatments for a substrate includes: a heating table for mounting the substrate thereon to perform the heat treatment for the substrate; a cooling table for mounting the substrate thereon to perform the cooling treatment for the substrate; a waiting table for allowing the substrate to wait; a carrying mechanism for carrying the substrate between the heating table, the cooling table, and the waiting table; and airflow formation means for forming airflow in a space in which the heating table, the cooling table, and the waiting table are arranged. Since the substrate is mounted on the cooling table during the cooling treatment, the cooling treatment can be performed for the entire substrate uniformly. Thus, the apparatus, in which precise cooling treatment is performed without delay, is excellent in time management on the heat and cooling treatments. Therefore, it is possible to make in-plane temperature distribution of the substrate uniform and to make the cooling effects on substrates the same even when the cooling treatment are performed for a plurality of substrates. Further, the apparatus can conduct the shift to the precise cooling treatment more promptly than before, thereby preventing deformation and deterioration in reproduction of a pattern.
