Title: Vibration damping construction for rolling roll
Inventor: INAGAKI TAIICHI
IPC: B21B37/00
Filed: 1985-03-29
Abstract: PURPOSE:To suppress the clattering vibration of a rolling roll and to prevent the surface defect such as stripe pattern of a rolled product by constituting a cylinder filled with a viscous oil in a supporting part for a roll bearing. CONSTITUTION:A work roll 1 and a roll bearing 4a are going to oscillate by receiving fluctuation load when rolling is started. An orifice 10 is bored to a piston part 9a of a piston 9 and the viscous oil 8 flows forward and backward through the orifice 10. A cushion effect is applied to the movement of the piston 9 by the fluid resistance developed by the flow of the viscous oil 8 having high viscosity through the small-diameter orifice 10 when the piston 9 moves by the transmission of the movement from the roll bearing 4a. A cushion effect is therefore applied also to the movement of the roll bearing 4a to which the piston 9 is pressed by a spring 11. The vibration of the work roll 1 and the roll bearing 4a is thus damped.

Title: Multiple liquid crystal panel stereographic image display device
Inventor: HARAGUCHI MASAYUKI
IPC: G02B27/22
Filed: 1999-02-04
Abstract: PROBLEM TO BE SOLVED: To obtain a panel which can be used for plural observers at a time, which gives more natural parallax and convergence for human eyes so as to reproduce a stereographic image as a real image and which decreases fatigue of the observers by piling plural liquid crystal panels. SOLUTION: When polarizing filters which pass only perpendicularly polarized waves and two display liquid crystal panels are used, only perpendicularly polarized waves in the incident light from a back light source are first passed through the polarizing filter. Then the light enters a lower liquid crystal panel, in which the light is polarized in the region with no voltage applied while the light is not polarized but transmitted as it is in the region with voltage applied. Then the light enters an upper liquid crystal panel and propagates in the same mechanism as in the lower panel. On a polarizing filter at the exit, only perpendicularly polarized waves are passed to enter eyes of observers. The background image is shown in the lower liquid crystal panel while the front image is shown on the upper liquid crystal panel.  Since the two images are spatially apart from each other, the observer feels the background image and the front image as real images by the parallax and convergence of eyes.
