Title: Manufacturing capacitor of semiconductor memory device by two-step thermal treatment
Inventor: WON SEOK-JUN
IPC: H01L21/8242
Filed: 2001-06-27
Abstract: A capacitor of a semiconductor memory device is manufactured using a two-step thermal treatment. A lower electrode 20 is formed on a semiconductor substrate 10. A dielectric layer 40 is formed over the lower electrode possibly with a silicon nitrate layer 30 therebetween. An upper electrode 50 formed of a noble metal is formed over the dielectric layer. The resultant having the upper electrode undergoes a first thermal treatment under a first atmosphere including oxygen at a first temperature which is selected to be within a range of 200-600{C, which is lower than the oxidation temperature of the upper electrode. The first thermally treated resultant undergoes a second thermal treatment under a second atmosphere without oxygen at a second temperature which is selected to be within a range of 300-900{C, which is higher than the first temperature. The first thermal treatment is of a duration sufficient to accumulate oxygen atoms at an interface between the upper capacitor electrode and the dielectric layer. The temperature during the second thermal treatment is sufficiently high to cure the dielectric layer through diffusion of the accumulated oxygen into oxygen vacancies within the dielectric layer.

Title: A method of logging message activity
Inventor: STANFORD-CLARK ANDREW JAMES
IPC: H04L12/24
Filed: 2001-08-09
Abstract: A reduction in the amount of information written to a log used to track message activity in a messaging system is achieved by not logging message data in a log record for the put of a message if the message data has been included in a previous message and is already available in the log. On receipt of a put request a check is made to see if there is a previous occurrence of the message data in the log. If there is not a previous occurrence a log record is written which includes the message data, but if there is a previous occurrence a log record is written which does not contain the message data but a reference which can be used to locate the previous occurrence of the message data in the log. Preferably the application includes an indication on the put request that the message data has been previously used.

Patent GB-2384632-A (GB)
Title: A power MOSFET with integrated short-circuit protection
Inventor: FINNEY ADRIAN
IPC: H03K17/082
Filed: 2002-01-25
Abstract: When the voltage on the drain of power MOSFET 1 increases, the small transistors 8 and 5 turn on, diverting gate charge from power MOSFET 1. The diode-connected transistor 5 and the main MOSFET 1 form a current-mirror when the current limit circuit is active. The maximum current in the main MOSFET 1 is set by the resistor 7 and the area ratio of the main and control transistors 1,5. Offset voltage V is optional. The sense transistor 8 uses a number of sensing cells in the main transistor (figures 3 and 4). The gates of the main and sense transistors are separated by omitting source regions in the body regions adjacent the sensing cells. Sensitivity of the short-circuit detector may be increased by an amplifying sense circuit (figure 2). The protection circuit does not prevent large currents flowing at low drain voltages, which can occur with inductive or capacitive loads.

Title: Anti-copy protection for a video signal
Inventor: WIJNEN ARIE
IPC: H04N5/775
Filed: 2002-02-01
Abstract: An apparatus and method for applying anti-copy protection to a raster-scanned video signal are described. In a first aspect, a square waveform 52 is added to the vertical synchronisation pulses 50 of the video signal. The effect of the waveform is not apparent until it has been recorded by a video cassette recorder. The anti-copy protected video signal can therefore be viewed normally on a display device at or near to the picture quality intended by the originator of the video signal, but once recorded, exhibits a reduction in picture quality which makes the video signal quite unattractive to view. In a second aspect, a positive-going pulse 94 is added to the back porch of the raster-scanned video signal such that it is substantially contiguous with the negative-going horizontal synchronisation pulse 86. The effect of the pulse is again apparent following recording of the video signal by a video cassette recorder. A negative-going pulse 96 may be added after the color burst 92 and a further positive-going pulse 98 at the start of the active line 84.

Title: Safety belt pre-tensioner with deformable force limiting rod
Inventor: DENIS ARNAUD
IPC: B60R22/195
Filed: 2002-06-06
Abstract: A pre-tensioner for pre-tensioning a safety belt such as a vehicle seat belt comprises a cylinder 1 associated with a housing 2 containing a pyrotechnic charge 3 to be injected into one end of the cylinder to move a piston 17 within the cylinder. A wire or cable 9 which is connected to part of the safety belt and passes around pulley wheel 8 extends into the cylinder and is connected by a connector 14 to a deformable bar or rod 15 which extends through a bore in the piston to terminate in a coil formed from at least one turn 24 of the deformable rod or bar. The connector is contained within a spacer 26 which spaces the piston from the end of the cylinder whilst permitting the connector to move axially when tension is applied to the cable thus deforming the bar (see figure 3). The pre-tensioner is intended to allow limited seat belt payout so as to limit the force applied to an occupant of the seat belt when the pre-tensioner is triggered.

IPC: H03H11/12
Filed: 2003-04-09
Abstract: A low pass filter is described, having a cut-off frequency that is variable from under 7 MHz to over 26 MHz (fig.9). The filter, described as a linear channel select filter, may be used as an IF selector in a satellite broadcast tuner, an RF filter, and a channel selector. It may be used in a zero IF circuit.

Voltage-to-current converter 100 includes a FET circuit 120 (fig.6) and also a control voltage generator 110 (fig 5), which is a digital-to-analogue converter. The output current from the FET circuit 120 varies as a function of the input voltage Vin. The output current also varies linearly as a function of the control voltage Vc produced by the control voltage generator 110. Accordingly, the filter cut-off frequency can be linearly varied. The filter replaces a switched set of filters and results in a lower area being needed.

Title: Rotary switch with ratcheting feature
Inventor: FOSTER WILLIAM L
IPC: H01H19/11
Filed: 2005-02-16
Abstract: A rotary switch (102) for an electronic device (100) includes a bump stop (104) that triggers a ratcheting feature when hit. The range of the rotary switch (102) is expanded via the ratcheting feature. The ratcheting feature inhibits scrolling through a device parameter in one rotation direction and enables scrolling through the device parameter in the opposite rotation direction. Depending on which direction the bump stop (104) is hit, the parameter is either incremented or decremented. The range of the rotary switch can also be expanded by modifying the step size of the rotary switch based on the range of a selected parameter (504). The coarse step is then narrowed with each change in rotation direction (510, 518) based on current, previous and useable switch positions (512, 514).
