Title: Radar device
Inventor: TAMASADA TETSUO
IPC: G01S13/20
Filed: 1978-10-27
Abstract: PURPOSE: To increase greatly the clutter suppression performance by differentiating the transmission pulse repetition cycle of the short-distance detection exclusive beam with every wave angle scanning period and then giving the correlation process to the virtual target distance to decide the true target distance.  
     CONSTITUTION: The beam, featuring the repetition cycle of a shorter distance than the object detection distance and a high transmission pulse repetition frequency and to be used exclusive for the short distance, is provided newly to the electronic scanning array radar. In response to this, mobile target detector circuit 16 capable of switching between the long-distance MTI filter and the short-distance MTI filter is installed newly in place of the conventional mobile target detector circuit. Furthermore, the high transmission pulse repetition frequency is differentiated with every wave angle scanning period so that the true target distance may be obtained from the reception signal with which the true target distance could not hitherto obtained since its repetition frequency is too high. And the combining correlation process is carried out for the virtaul target distance obtained in each wave angle scanning period through distance correlation circuit 17. The result thus obtained is transmitted to signal process circuit 14, and the short-distance detection exclusive output is used in preference for the detection of the short distance.

Title: Bearing structure for motor
Inventor: YAMAMURA MASASHI
IPC: H02K5/173
Filed: 1998-05-15
Abstract: PROBLEM TO BE SOLVED: To provide a bearing structure for motor which can suppress the occurrence of vibration by imparting an unbalanced load to a ball bearing, with a simple constitution. SOLUTION: A shaft section 16b of a rear-end bearing shaft section 16 is rotatably supported by a ball bearing 18 housed in the housing section 12a of a motor housing 12. The inside diameter of an inner race 18b of the bearing 18 is larger than the outside diameter of the shaft section 16b. In addition, a wave washer 24 is put on the shaft section 16b, in a compressed state between a flange section 16a and the inner race 18b. Since the washer 24 has deformed sections formed on its side face at two spots which are separated from each other at irregular intervals, the reaction (load) of the washer 24 applied to one side face of the washer between the flange section 16a and inner race 18b is not uniform but becomes a nonuniform load (unbalanced load) which varies depending upon the location. Therefore, the inner race 18b supports the bearing shaft section 16 in an inclined state.
