Title: Filtering device for random noise based on data compression
Inventor: BARASU KEI NATARAJIYAN
IPC: H04B15/00
Filed: 1994-03-28
Abstract: PURPOSE: To design and realize a nonlinear noise filtering device by incorporating a compression processor, a decompression processor, and an optimization processor in the filtering device. CONSTITUTION: Sampled noise-containing input signals S(N, f) stored in a memory 33 are sent to a compression processor 34 as input signals. The processor 23 selects a prescribed loss or error tolerance parameter ε and outputs the parameter of the compression expression D(S, ε) of the signal S. An optimization processor 35 is connected to the processor 34 so as to send the loss or parameter εto the processor 34, to instruct the processor 34 to read out a sampled input value from the memory 33, and to generate the parameter. The processor 35 merely sends a compression function parameter from the processor 34 to a decompression processor 36 upon determination a knee-point ε* and the processor 36 reconstitutes an approximate function (g) based on the parameters D(S, ε*). The processor generates a filtered output signal (g) by synthesizing and combining various frequency components.

IPC: H03K5/26
Filed: 1996-03-14
Abstract: PROBLEM TO BE SOLVED: To reduce fluctuation in an output frequency of a VCO when phases of two input signals to the phase comparator circuit of the PLL circuit are coincident. SOLUTION: In response to a leading of reference signals RI, PI fed to C terminals of 1st and 2nd D-FFs 8,9 in this phase comparator circuit, the 1st D-FF8 receives an output signal *Q' of the 2nd D-FF9 and the 2nd D-FF9 receives an output signal *Q of the 1st D-FF8. Furthermore, the reference signals R1, P1 are delayed by 1st and 2nd delay circuits 10, 11 and used to reset the 1st and 2nd D-FFs 8, 9. Thus, the output signals Q, Q' are pulse signals with a prescribed width. Since the Q output signal is delayed by a 3rd delay circuit 12, FETs 14, 13 are conductive in this order and an output signal of a charge pump circuit goes to L level and then H level in this order. Thus, an output signal of an LPF 15 is a signal with a small level change.

Abstract: PURPOSE:To attain the continuous processing in a real time by avoiding temporarily the collecting jobs of undesired areas and allocating an extended area in case the result quantity of CPU calculation to be written is larger than the idle area of a memory part. CONSTITUTION:A CPU 1 performs calculations according to a user program given from an input part 5 and calculates the request storage quantity against the result of calculation. A boundary controller 2 stores the result of calculation in a normal mode memory area 7 in a memory 7 and at the same time subtracts the storage quantity requested to the result of calculation from the prescribed maximum storage quantity of the area 7. When an unused memory area has zero or the minus value, the storage quantity requested by the CPU 1 is subtracted from the maximum storage quantity of an extension designation mode extended memory area 8. At the same time, the result of calculation is written to the area 8. When the area 8 includes no unused area any more, the device 2 collects the undesired areas.

Title: Manufacture of semiconductor element
Inventor: SHINOHARA MAMORU
IPC: H01L21/76
Filed: 1988-03-14
Abstract: PURPOSE:To restrain the diffusion amount of an impurity diffused layer in the lateral direction and to augment the integration by a method wherein an N type epitaxial layer is selectively oxidized using a nitride film on an impurity diffused layer as a mask to advance the diffusion of the impurity diffused layer as well as an oxide film is formed on a substrate. CONSTITUTION:The surface of an N type epitaxial layer 11 in the region wherefrom a nitride film 14 is etched away is etched in around 1mum and simultaneously a boron diffused layer 13 diffused in the etching region is further etched away. Next, after removing a photoresist 15 using an organic solution, the layer 11 is selectively oxidized using the nitride film 14 as a mask. Thus, the boron diffused layer 13 is further diffused reaching a P type substrate 10 to isolate the N type epitaxial layer simultaneously forming an oxide film 16 in around 2mum in the selective oxide region on the N type epitaxial layer 11. The diffusion coefficient in the boron oxide film 16 being larger than that in silicon, the boron on the interface oxide film 16 is absorbed into the oxide film 16 during the deposition of the oxide film 16 so that the boron concentration in the boron diffused layer 13 near the oxide film 16 in the selective oxide region may be reduced to decrease the diffusion amount in the lateral direction.
