Title: Pump station
Inventor: MIYAUCHI SUNAO
IPC: E03F5/22
Filed: 1997-05-12
Abstract: PROBLEM TO BE SOLVED: To improve a function by keeping a plurality of pump wells communicated to each other, and discharging an inflow of water on the operation or a pump having an intake inserted in the prewhirl part of the prewhirl tank of each pump well. SOLUTION: Water is prewhirled in the same direction as a pump impeller via prewhirl parts recessed on the prewhirl tanks 8A and 8B of pump wells 2 and 3, and a water level for stopping the pumps P1 and P2 is lowered for reducing the sizes of the wells 2 and 3. The wells 2 and 3 are kept communicated to each other through a communication passage 13, and an effective water storage volume doubles to a sum of the effective water storage volumes of the wells 2 and 3, even if the sizes of the wells 2 and 3 are reduced. Thus, a time for the water levels of the wells 2 and 3 to reach operation stopping water levels during the operation of the pumps P1 and P2, becomes longer and a water level rises to an operation starting level after an operation stop, thereby extending a time up to an operation re-start as well.  Also. even when diverting volumes to the wells 2 and 3 are not uniform, loads on the pumps P1 and P2 of the wells 2 and 3 become uniform as the wells 2 and 3 have the same water level via the communication passage 13. As a result, an adverse effect on the pumps P1 and P2 can be lessened via the reduction of a pump starting and stopping frequency.

Title: Obstacle detector apparatus
Inventor: ICHIKAWA SHOJI
IPC: G01S13/931
Filed: 1999-04-28
Abstract: PROBLEM TO BE SOLVED: To reduce the sense of discomfort given to a driver by preventing alarms or automatic controls not always needed for collision avoidance from execution. SOLUTION: A collision possibility estimating means M3 compares a future moving locus of an obstacle estimated by an obstacle locus estimating means M1, based on an output of a radar S1 with a future moving locus of own vehicle estimated by a vehicle locus estimating means M2, based on outputs of a wheel velocity sensor S2 and a yaw rate sensor S3, thereby estimating the possibility of collision of own vehicle against the obstacle. The radar S1 giving obstacle data to the obstacle locus estimating means M1 has a detection period of 100 msec but the obstacle locus estimating means M1, the vehicle locus estimating means M2 and the collision possibility estimating means M3 estimate the collision possibility in shorter estimating periods than that detection period of 100 msec.  Thus, without reducing the target detection period of a target detecting means and without using a large high-cost radar S1 having a short detection period, the estimation accuracy can be raised by estimating the collision possibility in a short estimation period.
