Filed: 1999-06-10
Abstract: The invention relates to a method for producing a semiconductor memory component, in particular, a DRAM or FeRAM, comprising a silicon substrate. At least one memory capacitor is located on said substrate, comprising a lower electrode, upper electrode and a dielectric layer which lies between said electrodes and which consists, in particular, of a ferroelectric material. The lower electrode is insulated from the silicon substrate by a barrier layer, consisting in particular of a diffusion barrier or a diffusion barrier combined with adhesive layers to form a sandwich. Said adhesive layers consist, in particular, of Ir, IrO2, or IrO. The barrier layer is structured before the application of the memory capacitor, using a hard mask consisting in particular of SiO2, SiN, SiON. The hard mask layer which remains after structuration is removed by uncovering the structured barrier layer. The invention is characterised in that the structured barrier layer is embedded in SiO2, using CVD (Chemical Vapour Deposition) before the removal of the remaining mask layer and that the remaining mask layer is removed with the SiO2 embedding layer from the surface of the barrier layer, using a SiO2 CMP (Chemical Mechanical Polishing) process.

Title: Rear derailleur control and actuation mechanism for racing road bicycle, comprises electronic control and actuation with an electronic display
Inventor: CAMPAGNOLO VALENTINO
IPC: B62M9/12
Filed: 1999-09-03
Abstract: The bicycle comprises a chain set that includes the crank assembly, the rear derailleur and the chain, the crank comprising chain rings (1,2,3) of differing sizes. A sensor (17) monitors the position of the gear selection lever (13) and is linked to a command unit (18) that shifts the chain across the chain rings and the rear sprockets to affect gear selection. The selected gear is displayed on a display unit (19).  The control and sensor units also monitor the position of the chain in relation to the chain rings and sprockets against the selected gear to ensure that no extremes of chain movement either across the chain rings of sprockets is affected. It also ensures that extreme chain positions are not utilized resulting in the chain being stretched and what is commonly known as a crossed chain, an example of which being a large chain ring and large sprocket combination. The controller will select an equivalent combination that results in the same gear.

IPC: G11C11/407
Filed: 1999-09-17
Abstract: The internal clock generating circuit comprises an input buffer circuit (202), a reset circuit (206), and a dynamic inverter circuit (204).  The input buffer circuit buffers an external clock signal (XCLK) to output an input signal complementary to the external clock signal. The reset circuit generates a reset signal of a pulse form after the input signal is activated and a time has elapsed. The dynamic inverter circuit inverts the input signal to output the inverted input signal as an internal clock signal for data-output. The dynamic inverter circuit is inactivated in accordance with the thus generated reset signal.

Patent EP-1130839-A1 (EP)
Inventor: HAKENBERG ROLF
IPC: H04N19/89
Filed: 2000-03-02
Abstract: The invention relates to a method and apparatus for transmitting and
receiving video data arranged in data frames forming a data stream. Each frame
has assigned a priority level. Once a data frame has been transmitted through an
unreliable channel and has not been received at the receiver, the priority level of the
missing data frame is compared with a priority threshold value, and is then
retransmitted if its priority level is greater than the priority threshold value. The
retransmission decision is performed either at the transmitting or at the receiving
side. According to a preferred embodiment, the priority level of any data frame to be
transmitted is compared with the threshold value. The priority decision may involve
the calculation of the priority threshold value based on a measurement of the
available channel bandwidths and eventually on the bit rate of previously sent
frames. The retransmission decision further may include an estimation of the arrival
time of the data frame to be retransmitted.
