Title: Servo-slope type fm-cw radar device
Inventor: ISHIKAWA MINORU
IPC: G01S13/34
Filed: 1991-03-11
Abstract: PURPOSE:To prevent errors of distance measurement in an FM-CW radar system for detecting the distance to an object body existing in a relatively short distance using microwave. CONSTITUTION:A transmission signal frequency-modulated by a continuous modulation signal having a linear slope with constant amplitude is emitted as radio wave. The reception signal including the reflection from an object body is mixed with a part of the transmission signal and the frequency of the obtained beat signal is analyzed. When the voltage of the central frequency signal exceeds a certain threshold, the signal is judged to be reflection from the object and opening and closing of the servo-slope is executed. As the error detection of scattered objects is prevented, a highly reliable detection of the object is possible.

Title: Control method for electromagnetic powder clutch
Inventor: MIYAZAKI TAKASHI
IPC: F16D48/06
Filed: 1997-03-06
Abstract: PROBLEM TO BE SOLVED: To appropriately control following rotation torque of an electromagnetic powder clutch so as to improve shift feeling of a transmission by feeding a reverse exciting current in the electromagnetic powder clutch.
