Title: Rear wheel steering controller
Inventor: KATO MANABU
IPC: B62D101/00
Filed: 1997-05-27
Abstract: PROBLEM TO BE SOLVED: To provide a rear wheel steering controller capable of securing the improvement of the straight advancing stability of a 4WS vehicle and external disturbance stability by rear wheel steering during straight advancing. SOLUTION: The actual steering angle of a rear wheel is controlled based on a target steering angle δr obtained by summing up a first target steering angle δr1 as a feed forward control amount and a second target steering angle δr2 as a yaw rate feedback control amount. In a yaw rate control system, since a calculating handle angle Thc for calculating a target yaw rate ψt is outputted from a dead zone block 22, the target yaw rate ψt is not set in the small handle angle region of an actual handle angle Th. Thus, during the straight advancing of a vehicle, a vehicular yaw rate gain is reduced for a handle operation by a driver.  On the other hand, when a yaw rate is produced by an external disturbance during straight advancing, since yaw rate deviation is produced in a subtraction part 32, normal yaw rate feedback control is executed and the external disturbance stability of the vehicle is improved.

Title: Pulsating diaphragm type fuel pump
Inventor: YANAKA NOBORU
IPC: F04B11/00
Filed: 1997-05-12
Abstract: PROBLEM TO BE SOLVED: To enhance pump efficiency by applying positive pressure directional force without caring about damage and resonance of a diaphragm by superposing a plate member having a cantilever tongue piece-shaped flap piece on a pulse pressure chamber side surface of the diaphragm, and operating the flap piece as a pressure assisting member. SOLUTION: A flap piece 10 easily curves by being sucked by negative pressure of a pulse pressure chamber 7, and does not hinder displacement of a diaphragm 2 proceeding to the pulse pressure chamber 7. When negative pressure reduces, the diaphragm 2 is pushed by elastic restoring force of the flap piece 10, and is forcedly displaced toward a pump chamber 6. Therefore, when the pulse pressure chamber 7 is substantially put in an always negative pressure condition, in a using condition where only unidirectional driving force is applied to the diaphragm 2, the flap piece 10 properly displaces the diaphragm 2 by applying positive pressure directional force, and pump efficiency can be enhanced. The flap piece 10 comes into surface contact with the diaphragm 2 since it is formed by arranging a notch groove 11 in a plate member 3.
