摘要： In a tool holder, when oil supplied via an oil supply passage and an oil introducing passage reaches an atomizing space, the oil is atomized by an air flow of carrier gas consisting of compressed air, and then water supplied from a water supply passage and a water introducing passage is formed into a water drop in the atomizing space by an air flow of oil containing compressed air to generate the water drop with oil film in which the oil film is formed on a surface of the water drop. Since the water drop with oil film is supplied to a work piece through a top nozzle and an in-tool passage, the water drop with oil film is generated at an extremely close location to a tool, and therefore, responsiveness when supplying the water drop with oil film to the work piece can be enhanced.

摘要： A plurality of retaining grooves for rolling members are arranged in the inner cylinder. The retaining grooves have semicircular bottom halves and top halves having sector-shaped sections diverging radially outwardly. The rolling members are accommodated in the bottom halves of the retaining grooves and grease fills the top halves. Then, the inner cylinder is fit into the outer cylinder. In rotating the bearing, the rolling members are rotated by the bottom halves of the retaining grooves serving as a sliding bearing and rolled on the inner peripheral surface of the outer cylinder. When a heavy load is applied, the rolling members are pushed down to the same level as the outer peripheral surface of the inner cylinder, thereby distributing and supporting the load by the outer peripheral surface of the inner cylinder and the rolling members. Therefore, the present invention can provide a roller bearing which is made compact by omitting the retainer for the rolling members and which exhibits good lubrication performance and endurance, avoiding vibration and noises.

摘要： The system has an atomizer (3) for sputtering a fluid (54), and a transmission path (5) for the transmission of the fluid. The atomizer is arranged in the center of the transmission path so that flow rate of the fluid, present under pressure, is transferred by the path. A flow rate data signal indicates the measured flow rate. A controller (4) receives the signal and information from atomization of the fluid in the atomizer as an atomization data signal. The atomizer is controlled dependent on the flow rate data signal, so that a flow rate is equal to a preset flow rate.

摘要： The generator has an oil mist generating and charging unit (2) for producing and charging an oil mist (6), by a coronary discharge, from an oil that is sputtered by an oil injector (11). The discharge is produced by applying a high voltage between the injector and a coronary discharge electrode that is mounted away from the oil mist. A conveying device conveys the oil mist to an operating point by using air pressure.

摘要： A small bearing which has the characteristics of a sliding bearing having a small coefficient of friction and of a rolling bearing, includes an outer metallic cylinder, a plastic inner cylinder, rolling elements, and a collar, with a plurality of rolling element holding grooves being provided on the outer peripheral surface of the inner cylinder. The grooves are formed in parallel with the axis of the bearing, and the rolling elements positioned therein are rotatable. Grease can be applied to the outer peripheral sur#ace of the inner cylinder, which holds the rolling elements, and the entire inner cylinder is covered with the outer cylinder, with the end portions of the outer cylinder being bent toward the axis. By forming the metal components from an austenite-type stainless steel, the problem of corrosion may be overcome.

摘要： A lubricating-fluid distributor (10) comprises a main pipe (1) to be connected to a discharge port of a pump (P) of a lubricating system, a body (2) having a main flow passage (3) connected to the main pipe, and a plurality of discharge ports (5, 6,7) communicating with the main flow passage. The body is made of corrosion-resistant material. A method of manufacturing a lubricating-fluid distributor comprises the step of extruding a corrosion resistant material to form the body (2). Preferred materials are aluminium alloy, nickel alloy, stainless alloy, and plastics material.

摘要： A bearing comprises a metallic outer tube having a flange, a inner tube of resin having a flange, radial rollers, thrust balls and a collar. A plurality of roller receiving grooves are formed on the outer periphery of the inner tube, while a plurality of roller receiving recesses are formed on the flange of the inner tube. The receiving grooves are formed in parallel relation to the bearing axis. The receiving recesses are formed circumferentially in concentric relation to the bearing axis. Each of the rollers received respectively within the receiving groove is rotatable. Grease is possibly apply to an outer peripheral surface of the inner tube body and a flange surface thereof. The cylindrical outer tube covering the entirety has both ends which are bent toward the axis. As corrosion countermeasure, it is preferred to form metallic parts of the bearing with stainless steel.
