Title: Center valve type master cylinder
Inventor: ISHIWATARI ICHIRO
IPC: B60T11/16
Filed: 2000-02-08
Abstract: PROBLEM TO BE SOLVED: To effectively prevent the erosion of an annular seal member by minimizing the propagation of the hydraulic pressure taking into consideration the propagation of the hydraulic pressure to the outer circumference of a tip portion of the annular seal member 100.

Title: Power increasing system using centrifugal force
Inventor: KUBOSAWA TETSUO
IPC: F03G3/00
Filed: 2000-01-04
Abstract: PROBLEM TO BE SOLVED: To provide a power increasing system using centrifugal force which confines the centrifugal force in a rotary circle, makes absorption, not dispersion, and allows application to a wide field of rotary apparatuses, compared with a conventional system in which automatic centrifugal force generated in association with rotation is dispersed on the outside circumference of a rotary circle. SOLUTION: In a circle which a driving gear constitutes, a main motion gear and a weight gear for generation of centrifugal force are installed meshing in confronting at the apex of the circle of driving gear, and when rotation is statred round the main motion gear as fulcrum, the rotational centrifugal force acts on the weight gear which uses as fulcrum a supporting gear positioned in the confronting position, and the acting gravittional force serves as a pressure to the opposing side face in the rotating direction within the circle of driving gear. and the pressure becomes a rolling pressure for the main motion gear in the rotating direction by an intra-gear circle curved surface.  Accordingly the centrifugal force makes reaction in the rotating direction, but absorption of the reaction in the driving gear circle generates an action in the rotating direction on the contrary by the intra-circle curved surface, and a power increasing system using the centrifugal force is established.

Title: Noise-reducing lubricating grease for rolling bearing
Inventor: MIKAMI EISHIN
IPC: C10M117/04
Filed: 2000-03-07
Abstract: PROBLEM TO BE SOLVED: To provide a lubricating grease made proof against softening due to shear during the rotation of a rolling bearing, not causing insufficient lubrication on the friction surface of a bearing lubricated with a lubricating grease, being capable of stably rolling at a low torque without noise, and having a prolonged life. SOLUTION: This noise-reducing lubricating grease for a rolling bearing is prepared by adding 5-15 wt.% thickener containing at least 5 wt.% lithium salt of a 12-24C hydroxy aliphatic acid to a base oil containing at least 30 wt.% ester oil having a kinematic viscosity of 10-100 mm2/s (at 40 deg.C) and a solubility parameter of 8.3-9.0. The grease is the one that does not deteriorate so much in the action of a rolling bearing when it is subjected to shearing action during e.g. the rotation of a rolling bearing because the affinity of the base oil for the thicker increases to a value higher than the requirements and can operate a rolling bearing in the state in which its acoustic characteristics, i.e., noise-reducing properties can be maintained for a long term.
