Patent JP-H0699896-A (JP)
Title: Parachute
Inventor: KIMURA SATOHIDE
IPC: B64D17/34
Filed: 1992-09-17
Abstract: PURPOSE:To shorten the time required for slowing down at the falling time so as to allow the fall starting altitude to be set low by providing a sling length control means for pulling out a sling gradually from a sling holding part according to the falling speed of a falling body to make the length of the sling long. CONSTITUTION:When a falling body 10 continues to fall together with a parachute 1 with a sling 3 made short and the open shade diameter of a canopy 2 made small, the decrease of air resistance in association with this fall is detected as the tension of the sling 3 by a load cell 8. When this tension becomes smaller than the set load, a controller 9 is operated to output a brake release command to a brake lock 7, and a winding shaft 4 is rotated in the direction of an arrow mark to gradually pull out the sling 3 held in the wound state. As the sling 3 gradually becomes longer, the open shade diameter of the canopy 2 becomes large, and air resistance is gradually increased. Accordingly, during the fall of the falling body 10, the reduction ratio is kept to the specified value, and the time required for slowing down is shortened. The fall starting altitude can be thereby lowered.

Filed: 1990-09-18
Abstract: PURPOSE:To change over a damping force characteristic in a more desirable mode at special brake time and normal brake time by setting a change-over reference value of the damping force characteristic larger than that of normal brake time at the time of braking under a condition where a right and a left road surface conditions are different to each other. CONSTITUTION:A time-based change rate of damping force generated in a pair of left and right shock absorbers 2L, 2R is detected by a pair of left and right detecting devices 4L, 4R and, when this detection value exceeds a change- over reference value, a damping force characteristic is changed over from hard to soft by a shock absorber controller 6. In this case, difference between a left and a right damping force changing rates is computed by a means 8 and the computed difference is compared with a specified value by a comparation means 10. Further, a signal corresponding to whether braking is being applied or not is input to the shock absorber controller 6 by a means 12. A procedure 6a, which uses a relatively large value for the change-over reference value in the case where such a condition that braking is being applied and the computed difference is exceeding the specified value is realized, is incorporated in the shock absorber controller 6.

Filed: 1987-10-02
Abstract: The invention consists in manually inserting a first piece of fabric (49) into the bottom portion of an edge guide comprising three superposed plates (2, 3, 4). The piece of fabric is pushed towards the end of the edge guide by means of jets of air until the side (51) of the piece along which sewing is to be performed is aligned with an end abutment. A dog (17) placed beneath the bottom plate (2) presses the piece of fabric (49) against the bottom face of the middle plate (3) and then displaces it along the sewing line direction until the other side (52) of the corner has reached a reference line (53). A second piece of fabric (54) is manually inserted and is positioned in the same way as the first by means of a dog (18) placed above the top plate (4). Once both of the pieces of fabric (49 and 54) are exactly superposed, the dogs (17, 18) drive them simultaneously at the same speed under the presser foot (47) of the sewing machine.
