Filed: 1989-12-28
Abstract: PURPOSE:To allow for both riding comfort and steering stability by setting a soft retention period for a predetermined duration according to a rate of change in damping force when damping force is restored after it is changed from large to small and restoring the damping force from small to large when required. CONSTITUTION:A rate of change in damping force in a shock absorber M1 provided on a vehicle suspension S is detected by a means M2 as well as the damping force is controlled by a means M3 based on the detection value and a reference value of the damping force. In such an apparatus, when the rate of change in damping force is out of a range of a first reference value, the damping force is changed from large to small by a means M4. When the rate of change in damping force is maintained for a first period or longer within a range of a second smaller reference value, the damping force is restored from small to large by a means M5. A soft retention period from the change in the damping force to the recovery is calculated by a means M6.

Title: Door stopper
Inventor: CHOKAI KOJI
IPC: E05C17/54
Filed: 1997-12-15
Abstract: PROBLEM TO BE SOLVED: To open and hold a door securely at a desired open angle. SOLUTION: A door stopper 1 is formed in a wedge-shape by connecting a thin platy first surface side member 2 having a first surface 2a and a block- shaped second surface side member 3 having a smoothly formed second surface 3a to each other. The first surface side member 2 is formed of a material relatively large in coefficient of friction, and the second surface side member 3 is formed of a material smaller in coefficient of friction than the first surface side member 2. Then the door stopper 1 is caught between a lower end 21a of a door 21 and a floor when its second surface 3a is brought into contact with a lower end 21a of a door 21.  In this case, because the friction coefficient of the second surface 3a is smaller than the friction coefficient of the first surface 2a, the door stopper 1 does not almost move on the floor, and the door 21 is opened and held securely at a desired open angle.
