Title: Sampling system
Inventor: YAMADA KUNIHIRO
IPC: H04L7/02
Filed: 1999-04-21
Abstract: PROBLEM TO BE SOLVED: To use a D/A converter for D/A conversion at transmission with a D/A converter used for D/A conversion at reception in common. SOLUTION: The sampling system includes a 1st sampler SW1 that periodically samples an input signal IN for a fixed sample extract period T. A 1st low pass filter LP1 outputs a sample sequence resulting from shifting the phase of the input signal by -T/4. A 2nd low pass filter LP2 outputs a sample sequence resulting from shifting the phase of the input signal by +T/4. A 2nd sampler SW2 receives alternately the sample fed from the LP1 and whose phase is shifted by -T/4 and the sample fed from the LP2 and whose phase is shifted by +T/4 at a period being a half the period T and doubles number of output samples from the 1st sampler SW1 and outputs the result as a secondary sample sequence.  An interpolation circuit (Lagrange circuit) outputs an output sample sequence with a timing phase synchronously with a given optional clock signal by executing the interpolation of the secondary sample sequence that is an output of the 2nd sampler.

Title: Fuel injection factor control method for diesel engine
Inventor: YAMADA YASUO
IPC: F02D41/38
Filed: 1986-05-16
Abstract: PURPOSE:To reduce the generation of noise during low load running, by a method wherein the injection factor of feed fuel is controlled in response to a combustion noise detecting signal. CONSTITUTION:When it is decided by a controller 16 that a diesel engine 10 is in an idle running state, a final pilot injection control timing T, obtained by correcting a fundamental pilot injection control timing, responding to the number of revolutions, depending upon a cooling water temperature, is computed to drive a pilot injection device 14. Thereafter, at a point of time when a given time lapses, the pilot injection control timing T is staggered by DELTAT to the lead angle side or the angle of delay side, integrated values of combustion noise detected by combustion noise sensors 15 at each point of time are compared with each other. A fundamental pilot injection control timing is corrected by DELTAT in a direction in which the discriminated noise is decreased. Since this constitution enables the pilot injection control timing to be corrected so that it approaches an optimum value changed due to a change with time of a device, the generation of noise during idle running can be reduced.
