Title: Lubricant supply body
Inventor: YABE SHUNICHI
IPC: C10M171/00
Filed: 1999-03-16
Abstract: PROBLEM TO BE SOLVED: To obtain a supply body which supplies a lubricant to a member to be lubricated without adversely affecting the environment by incorporating a biodegradable lubricant into a polymer. SOLUTION: A biodegradable lubricant in an amount of 30-90 wt.% is incorporated. As an oily lubricant, a fatty acid diester or a polyol ester is suitable. In the case of grease lubrication, a grease using a thickening agent such as a lithium soap, a hydroxylithium soap, a calcium soap, a calcium-lithium soap, a composite lithium soap or an organic bentonite can be used. For example, when a polyurethane is used as the polymer, a grease containing both a liquid urethane prepolymer and an amine curative is poured into a metal mold and is molded under heating and pressure into a desired shape, When a polyurea is used as the polymer, a grease is mixed with an amine component and then with a polyisocyanate component and the resultant mixture is molded as above.  In the case of an ultra-high-mol.-wt. polyethylene, a porous body prepared by powder molding is impregnated with a lubricating oil under vacuum.

Filed: 1983-04-19
Abstract: PURPOSE:To obtain a video signal corresponding to left and right parallax images by switching alternately a pair of electronic shutters basing on a horizontal synchronizing signal corresponding to odd and even fields, in an image pickup machine contained in a stereoscopic television device. CONSTITUTION:In order to switch electronic shutters 33, 34, a phase discriminating circuit 57 and a flip-flop circuit 58 are provided.

On the contrary, in case of the even field, the shutter 34 becomes opaque, and the shutter 33 becomes transparent. Accordingly, an image pickup tube 5 outputs an electric signal corresponding to a parallax image of the left at the time of the odd field, and outputs an electric signal corresponding to a parallax image of the right at the time of the even field.

Title: Gas bearing structure
Inventor: SHIMADO KOJI
IPC: F16C27/06
Filed: 1990-03-20
Abstract: PURPOSE:To prevent the generation of vibration or the like to a rotor so as to apply the method of prevention to a high speed rotary machine rotatable in the constantly stable state by connecting together, via an elastic member, a radial shaft and a thrust shaft rotatably supported by radial and thrust bearing bodies respectively. CONSTITUTION:When the center line L of the rotor shaft 2 of a rotor R is not completely orthogonal to the plane P parallel to the thrust face of a thrust facing member 12, the direction of higher rigidity during rotation between the radial and thrust directions of the rotor R is position-regulated in priority, and an oscillating phenomenon is generated around the center-of-gravity of the rotor R. In this case, the radial facing member 11 and thrust facing member 12 of the rotor R are connected to each other by a rubber plate 14, so that the freedom of displacing a set angle by approximately + or -2mum at each member tip is allowed between both members 11, 12. The set angle of the member 11 or 12 is therefore changed according to the air pressure balance with a bearing body 5 or bearing bodies 6, 8 so as to prevent, to the utmost, a clearance toward the bearing body 5 or bearing bodies 6, 8 from becoming locally narrow. The rotor R is thus prevented from the generation of unstable vibrational moment.
