Title: Ceramic bearing
Inventor: HATANO KAZUYOSHI
IPC: F16C33/32
Filed: 1987-08-11
Abstract: PURPOSE:To obtain a ceramic bearing with high aliding characteristic by implanting ions in to the surface of a sliding member, forming a mixture/ compound layer between a lubricant film and a ceramic base member, and thereby improving contact strength therebetween. CONSTITUTION:A lubricant film 3 adheres to a ceramic base material 1 through a film made of a mixture of crystalline and noncrystal substances or compound on their boundary surfaces physically united together by means of ion implantation. Since either on of lead, silver, tin, molybdenum disulfide and boron nitride is ionized and implanted into the sliding surface of a ceramic bearing, adhesion strength between the mixture/compound layer formed on the sliding surface and the ceramic base material is remarkably improved in comparison with other processes, (for example, an ion plating). Abnormal abrasion or peeling from the ceramic base material during sliding motion is prevented, and bearing characteristic with stability and high reliability can therefore be obtained.

Abstract: PURPOSE:To enable the detection of the existence and the type of an object buried underground by burying a sealed container sealed with an odorized fluid, a colored fluid and the like into the soil above the object to recognize odor or color associated with the breakage of the sealed container. CONSTITUTION:For example, a hollow capsule 2 formed oval or spherical from a hard synthetic resin or the like is sealed with an odorized gas having an aromatic odorant added to an N2 gas or a colored gas having a coloring agent added to the N2 gas at a low pressure. It is desired to vary odor and color of the odorant and coloring agent with the type of a buried pipe 1. The capsule 2 thus obtained is buried into the soil 34 between a pavement 30 and the buried pipe 1 being placed into a container 3 or as intact. When the pavement 30 is cut and broken with a concrete cutter and a pavement breaking machine to carry out repairs of roads, the gas sealed is radiated as the capsule 2 is broken with the cutter or the like. Thus, the odor of the odorant or color of the coloring agent allows the detection of the burying of the pipe 1 below and the type thereof thereby enabling the prevention of breakage thereof.
