Title: Damping force regulating type hydraulic shock absorber
Inventor: NAKATATE TAKAO
IPC: F16F9/44
Filed: 1996-06-20
Abstract: PROBLEM TO BE SOLVED: To improve the degree of freedom of setting the damping force characteristic in a damping force regulating type shock absorber. SOLUTION: A piston 5 connecting a piston rod 6 is installed to a cylinder 2, and a reservoir 4 is connected through a check valve 16. Cylinder upper chamber and cylinder lower chamber 2a and 2b are communicated by an oil passage 11, and a disk valve 12 is provided to the oil passage 11. The cylinder upper chamber 2a and the reservoir 4 are communicated through a damping force regulating mechanism 17. Together with the expansion and contraction strokes of the piston rod 6, the oil liquid flows to the reservoir 4 from the cylinder upper chamber 2a through the damping force regulating mechanism 17, and a damping force is generated by the damping force regulating mechanism 17. In the contraction stroke time, the oil liquid flows from the cylinder lower chamber 2b to the cylinder upper chamber 2a through the oil passage 11, and the damping force is generated also by the disk valve 12.  Since the damping force characteristic at the contraction side is changed by the characteristic of the disk valve 12, the degree of freedom of setting the damping force characteristic can be improved.

Title: Electrostatic eliminator
Inventor: TAWATARI HIROHITO
IPC: H05F3/02
Filed: 1997-06-20
Abstract: PROBLEM TO BE SOLVED: To absorb even abrupt removing charges and to prevent a substrate provided with transparent electrode from being scratched after discharge by providing a vertical movement mechanism to move up and down a discharging terminal synchronizing with the vertical movement of the substrate provided with transparent electrode. SOLUTION: A vertical cylinder 14 move up and down at a same timing as separation of the substrate 10 with transparent electrode from a stage 11. A discharging terminal 12 and a dummy terminal 13 are kept in contact with the substrate 10 during the separation movement, and are completely separated from the substrate 10 at the time of finishing the separation movement. Since the discharging terminal 12 is grounded while the discharging terminal is in contact with the substrate 10, static electricity on the substrate 10 caused by an abrupt separation charging is absorbed. If either the discharging terminal 12 or the dummy terminal 13, or both are not in contact with the substrate 10 while the substrate 10 is being separated from the stage 11, an analog displacement gage 17 reads an abnormal value.
