Title: Unified framework implementing cosine modulated filter banks (CMFBs)
Inventor: LIOU CHI-MIN
Filed: 1998-07-29
Granted: 2000-02-21
Abstract: A unified framework for implementing modulated cosine transforms (MCTs) of various cosine modulated filters in audio compression standards. Said unified framework comprises a switch module and a transform calculation module. The calculation of a modulated cosine transform is done by first calculating through the switch module, and then the discrete cosine transform. The calculation of a reverse modulated cosine transform is done by first calculating a discrete cosine transform, and then calculating through the post switch module. In said unified structure, the computed discrete cosine transform is selected from the cosine transform groups of type-II, type-III, or type-IV. The calculation of the N-point discrete cosine transform is decomposed into three steps: the switch-addition step, the sub-transformation step, and the combination step. The sub-transformation step is selected from the calculation of two N/2-point discrete cosine transforms in the same group. The use of said unified structure generates a good regularity, has more popular applications, and a reduced complexity.

Title: Manufacture method of cup-shape capacitor for dynamic random access memory
Inventor: LIN YE-SEN
IPC: H01L27/108
Filed: 1998-12-14
Granted: 2002-10-01
Abstract: This invention provides a manufacture method of cup-shape capacitor for dynamic random access memory. An etching stop layer is formed on top of a dielectric layer and an anisotropic etching process is performed to etch the dielectric layer using a resist pattern as an etching mask. The above-mentioned anisotropic etching process will generate a plural number of trenches in the dielectric layer, and an isotropic etching is subsequently carried out to produce a plural number of cup-shape recesses. Then, contacts holes are formed by performing another anisotropic etching process to etch the film layer to the substrate, which is followed by stripping off the resist pattern. A conductor layer is deposited on the surface of the dielectric layer and along sidewall of the contact holes. Recess filler material fills back into the cup-shape recesses and the top portion of the conductor layer has to be exposed by the filler material. A selective etching is employed to etch the conductor layer where there is no coverage by the filler material. A first electrode of the cup-shape capacitor is formed after the dielectric layer and the filler material is removed by wet etching. In the next step, a dielectric film is deposited along the surface of the cup-shape capacitor to function as a dielectric layer for the capacitor and another conductor layer is formed on the dielectric layer of the above-mentioned capacitor.

Title: Desulfurization of flue gas using active carbon catalyst
Inventor: KAWAMURA KAZUSHIGE
IPC: B01J21/18
Filed: 1999-04-07
Granted: 2002-09-01
Abstract: An active carbon catalyst shows an improved activity and an enhanced stability to adapt itself to recovering and removing sulfur oxides contained in flue gas by turning them into sulfuric acid by a catalytic desulfurization reaction. Powdery active carbon and fluororesin are mixed and kneaded by applying shearing force to the mixture before it is molded to a desired profile such as granular, plate-shaped or pillar-shaped so that the inter-particulate gaps of powdery active carbon particles are made water-repellent. Flue gas is preferably made to flow downwardly through a tower filled with such an active carbon catalyst. Then, the catalyst is made to show a honeycomb structure having surfaces running only in a direction parallel to the flow. The activity of the catalyst will be maintained to an enhanced level if dilute sulfuric acid or water is introduced into the active carbon from the top of the tower to cleans the surface of the active carbon catalyst. Then, the catalyst layer may be prevented from being clogged and contaminated by ashes and soot contained in flue gas.

Title: Disk drive
Inventor: SAKAI MASAKATSU
IPC: G11B19/02
Filed: 2000-03-08
Granted: 2003-04-01
Abstract: The present invention aims to overcome difficulties in changing the maximum current of a floppy disk drive (FDD), which is connected with a computer through an universal serial bus (USB), to be below 500mA. The light emitting diode (LED, 12) used for indicating the operation states of a FDD does not light up continuously during search but lights up during the peak current interval of a stepping motor (16) that is not used for transporting magnetic heads (4, 5). Thus, the sum (Im+Id) of the current (Im) of stepping motor (16) and the current (Id) of LED (12) can be kept low.

Title: Magnetic disk drive, position controlling method of magnetic heads and recorded medium storing program of the method
Inventor: SHIGEMATSU NORIO
IPC: G11B5/55
Filed: 2000-05-08
Granted: 2003-10-01
Abstract: In a magnetic disk drive, the time required for that the magnetic head brought into the off-track state due to vibration or shock restores into the on-track state, is shortened. A selector 15 selects, as the magnetic head position information, either the position information estimated by an observer 16 or the position information detected from a magnetic disk 22, depending on the degree of vibration or shock, the presence of a detection error of servo information and the degree of an estimating error. The position information selected is used in the calculation of a control value of the actuator. Accordingly, the estimated position information is used if there is a fault in the detection of servo information or detected servo information is probably inaccurate. Therefore, the magnetic head can restore rapidly from the off-track state to the on-track state.

Granted: 2003-03-21
Abstract: The invention provides a novel scanning technique aimed at reducing the phenomenon of contouring. The scanning technique of the invention consists in adding at least one redundant subscan SP0 to SP4.
