Title: Radar receiver
Inventor: ISHII YOSHIHIRO
IPC: G01S7/34
Filed: 1991-04-17
Abstract: PURPOSE:To enable a sea-level reflection to be effectively controlled by performing a constant signal processing for a radar video signal and switching to an optimum kind of amplitude control signal of a voltage-controlled amplifier according to switching of application/non-application of the signal processing. CONSTITUTION:When signal processing, for example, peak processing, is performed, a sampling circuit 10 writes a radar video signal which is converted by an A/D converter 7 into a primary memory 11 at a constant timing. A comparison circuit 12 compares contents of the memory 11 with those of an image memory 18 and then updates the memory 8 at a higher level. When no peak processing is performed, the contents of the memory 11 are written into the memory 8 as they are. At this time, a switching signal of the peak processing is given to an STC (sea-level reflection control) voltage generation circuit and the type of amplitude control signal is switched. When the peak processing is performed, the amplitude is reduced immediately after a transmission trigger is generated. When it is not performed, the amplitude is not reduced greatly, thus enabling a voltage-controlled amplifier to be controlled and preventing an object target from being lost due to an excessive suppression of the sea-level reflection near a screen center.

Title: Power steering device
IPC: B62D5/04
Filed: 1992-03-10
Abstract: PURPOSE:To suppresses vibration of a steering wheel owing to unevenness on a road surface and to improve a steering feeling by increasing apparent moment of inertia of a steering system. CONSTITUTION:The detected value of an acceleration sensor attached to a rack is analyzed by a frequency analyzer 54 and a frequency (n) responding to a peak of acceleration is determined. From the frequency (n), inertial moment I is determined and correction torque T3 is calculated from a product of the I and steering angle acceleration theta'' and a drive command value for an electric motor 42 is calculated through correction of aiding torque T2 set by an aiding torque setting part 60. The inertial moment I is decided to a high value when acceleration is caused by the change in vibration of a road surface reaction force owing to unevenness in a road surface and the frequency (n) is high. By decreasing the aiding force of the electric motor 42, apparent moment of inertia of a power steering device is increased and vibration is difficult to occur in a steering wheel.
