Title: Interference cancellation in radio stations
Inventor: ESMAILZADEH RIAZ
IPC: H04B1/707
Filed: 2000-01-25
Granted: 2002-07-11
Abstract: The invention is concerned with a radio receiver station, a multi-user interference cancellation unit and a multi-user cancellation method in a system with several transmitting radio stations. In the method, a radio signal is received as a sum of the signals from at least two of the transmitting radio stations in the system. Interference from at least two of the transmitting radio stations is cancelled. The interfering signals from at least some of the transmitting radio stations are processed in at least two separate operations in one or more stages, the result of each separate operation being taken into consideration in the estimation of the desired modulated signal sent to the receiver. Preferably, a part of the interfering signals is processed in one of the separate operations, while the rest of the interfering signals are processed in the other separate operations. If the cancellation is carried out in more than one step, the cancellation results of the first cancellation stage are used in the second interference cancellation stage, the method being correspondingly continued in the possible further cancellation stages.

Title: Disc controller, disc control system, and disc controlling method
Inventor: HASENO SHINICHI
IPC: G11B19/04
Filed: 2000-04-11
Granted: 2004-04-01
Abstract: In the disc controlling system, a buffer memory stores sector by sector data read from a disc or data to be written to the disc. A memory controller allows a floppy disc drive to intermittently read sector by sector data from the disc for supply to the buffer memory or intermittently write sector by sector to the disc data supplied from the buffer memory. When the floppy disc drive is not writing data to or reading data from the disc, data read from the disc is supplied sector by sector from the buffer memory to the system bus or data to be written to the disc is supplied sector by sector to the buffer memory from the system bus.

Inventor: KATSUMATA HIROFUMI
IPC: C23C16/52
Filed: 2000-04-19
Granted: 2001-10-21
Abstract: The present invention provides a wafer heating device which can improve uniformity of a temperature distribution within a surface area of a wafer, with a relatively simple structure. A wafer is supported on a susceptor of annular shape. A first heater of disc shape is disposed below the wafer, and a second heater of annular shape is disposed to surround the first heater. Radiation thermometers are arranged at a ceiling portion of a reaction chamber. The first radiation thermometer measures a temperature of a central area of the wafer, the second radiation thermometer measures a temperature of a peripheral area of the wafer, and the third radiation thermometer measures a temperature of the susceptor. The first heater and the second heater are controlled by independent closed loops. When a wafer is set on the susceptor, a power of the second heater is controlled by using a value measured by the second radiation thermometer as a feedback signal. When no wafer is set on the susceptor, the power of the second heater is controlled by using a value measured by the third radiation thermometer as a feedback signal.

Title: Synchronous semiconductor storage device
Inventor: INOUE KOUJI
IPC: G11C7/12
Filed: 2000-06-29
Granted: 2002-01-11
Abstract: In a synchronous semiconductor storage device, upon latching potentials of a bit line (BL0-BL7) by a sense amplifier (12) in a read operation, a bit line disconnecting circuit (II) disconnects the bit line (BL0-BL7) and an associated reference line from the sense amplifier (12) until a next read operation. At the same time, a virtual GND line disconnecting circuit (13) disconnects a corresponding virtual GND line (VG0-VG7) from the ground potential until the next read operation. After the disconnection of the bit line (BL0-BL7), the reference line, and the virtual line (VG0-VG7), the precharge operation of the bit line (BL0-BL7) and virtual line (VG0-VG7) by the VREF level supply circuits (2, 4) is performed in parallel with the amplifying operation by the sense amplifier (12). This allows an access with a CAS latency of 3.

Title: Subscriber station, network control means and method for triggering inter-frequency measurements in a mobile communication system
Inventor: PETERSSON JUSTUS
IPC: H04B7/005
Filed: 2000-08-29
Granted: 2002-02-21
Abstract: A quality measurement means (QMM) provided in a network control means (RNC) of a communication system (T1) monitors the transmission quality on the down link (DL) of a communication connection (CC) between the subscriber station (MS) and the base transceiver station (RBS). A network IF handover means generates a network IF measurement trigger signal (NIFTS) when the transmission quality drops under a predetermined quality measure (QoS-MS). The generated network (IF) measurement trigger signal (NIFTS) is sent to the subscriber station (MS) and an IF measurement means (IFMM) in the subscriber station (MS) starts the IF measurements in response to a receipt of the network IF measurement trigger signal (NIFTS). One example of evaluating the quality on the down link of the communication connection (CC) is to monitor the transmitted output power on the down link. Thus, the network control means (RNC) can independently generate the trigger signal without the need of measurements from the subscriber station (MS) and without an additional interference on the up link due to a transmission of such measurements and without an unnecessary reduction of the lifetime of the battery of the subscriber station (MS).

Apertures (74) are created through the track layer by a process that entails etching along the tracks. The aperture-containing polycarbonate track layer is typically used in fabricating a gated electron-emitting device.

Granted: 2003-05-01
Abstract: The present invention discloses a method for automatic safe recovery of defective basic input-output system (BIOS) memory device in a computer system having two BIOS memory devices. A main BIOS memory device and a safe recovery BIOS memory device storing a first BIOS utility and a second BIOS utility, respectively, are included in a computer system having two BIOS memory devices for starting the operation of the computer system. A BIOS flash utility is also included in either the main BIOS memory device or the safe recovery BIOS memory device. When the computer system is powered on, the safe recovery BIOS memory device is enabled before using an error detecting circuit to check whether there is any error in the first BIOS utility stored in the main BIOS memory device. If an error is found, the BIOS flash utility is applied to re-program the main BIOS memory device according to the contents of the safe recovery BIOS memory device. Then, a chip enabling (CE) circuit is applied to disable the safe recovery BIOS memory device and enable the main BIOS memory device for the main BIOS memory device to carry on the power-on procedure of the computer system.
