Title: Radar transmitter and receiver
Inventor: NIRASAWA TOMIJI
IPC: G01S7/02
Filed: 1984-12-31
Abstract: PURPOSE:To decide on the display of a correct target by obtaining the frequency of an IF radar received wave without any shift from the center frequency of an IF amplifying circuit. CONSTITUTION:A leak IF radar transmitted wave IF-T3 based upon a leak RF radar transmitted wave RF-T4 supplied to a frequency converting circuit 5 through a transmission/reception switching circuit 2 through a radar transmitter 1 is supplied to a frequency discriminating circuit 9 only when it is lower than the threshold level of the circuit 9. Even if here is disorder at the start and end of the on section of the received wave IF-T3 of the circuit 9, a signal CE for frequency control obtained from the circuit 9 has a value which is not affected by the frequency of disorder at the start and end of the on section of a transmitted wave RF-T1 from a transmitter 1 because the transmitted wave IF-T3 is lower than the threshold level of the circuit 9. Therefore, the frequency of the received wave IF-R1 of the circuit 5 has no shift from the center frequency of an IF amplifying circuit 6, and the display of a target on a radar display device 8 allows its kind and shape to be discriminated correctly.

Title: Method and device for transferring lambda mean value
Inventor: GEORUKU MAREEPURAIN
IPC: F02D41/14
Filed: 1992-10-15
Abstract: PURPOSE: To provide an arrangement for shifting a lambda mean value that can almost ensure a desired lambda mean value shifting even a noise exists. CONSTITUTION: A control deviation RAW between the practical value indicating the lambda value of an engine exhaust gas and a predetermined fixed value is formed, the control deviation is then integrated to form an operation component RF. The integration is conducted in the direction of higher integration values in the case of presence of a control deviation indicating a lean mixture, and in the direction of lower integration values in the case of presence of a control deviation indicating a rich mixture. The integration stops temporarily while the sign of the control deviation changes to the sign that belongs to the desired lambda value shift. In this time, the integration stops over the entire integration stop time span only when the operation component is in a value range that belongs to the shift of the lambda mean value in the desired direction.  In this way, the integration stop time span provided only for the rich region does not function in the lean region caused by the noise.
