    摘要： The present invention provides a producing method of R-T-B-based sintered magnets in which, the recovery chamber 40 includes inert gas introducing means 42, evacuating means 43, a carry-in port, a discharge port 40a, and a recovery container 60. The recovery step includes a carrying-in step of conveying a processing container 50 into the recovery chamber 40, a discharging step of discharging coarsely pulverized powder in the processing container 50 into the recovery chamber 40, a gas introducing step of introducing inert gas into the recovery chamber 40, and an alloy accommodating step of recovering the coarsely pulverized powder into the recovery container 60. Addition of pulverization aid is carried out in the alloy accommodating step. A remaining amount of coarsely pulverized powder in the recovery chamber 40, an oxygen-containing amount of the R-T-B-based sintered magnet is reduced, and magnetic properties are enhanced.

    摘要： On a faceplate having a phosphor layer and a metal back that are formed on a substrate, in a vacuum atmosphere, for instance an active Ba film is deposited as a getter film. Following this, while maintaining the vacuum atmosphere, the faceplate thereon the getter film is deposited and a rear plate having a plurality of electron emitters formed on a substrate are oppositely disposed to form a gap therebetween through a support frame, the gap being hermetically sealed. A flat panel display comprises the active Ba film formed on for instance the metal back as a getter film. Such getter film, while maintaining an activity, is disposed on an image display region in a vacuum vessel, having an excellent getter function.

    摘要： This invention relates to a driving mechanism of an air bearing journaled handpiece for dental treatment, the mechanism being improved in that even when a load contrary to the direction of rotation of a tool shaft such as cutting of the teeth acts upon the tool shaft in a dental operation, rotation of the tool shaft does not stop because of load resistance but enables the heretofore, unmaterialized medium-speed cutting (hereinafter referred to as "extension to medium-speed rotation") and makes it possible to obtain improved torque during high-speed rotation in addition to the extension to medium-speed rotation.

    摘要： A dental hand-piece with an air turbine wherein a collet chuck holding a cutting tool spindle, a clamping member enough to clamp tapered chuck pawls of the collet chuck convergently from the outside, and further a moving element allowed to do the fine movement toward the outside owing to the centrifugal force acting thereon during the rotation of a rotary body are all together incorporated into the turbine rotary body supported by a shaft bearing inside a head casing, and which hand-piece is so designed in such manner that the fine movement of the moving element can provoke the sliding movement tending to clamp the chuck pawls between the collet chuck and the clamping member, is disclosed. In this hand-piece, the chuck pawls are automatically clamped at the time when the turbine rotary body starts to rotate, and the holding force of the collet chuck becomes greater to perform the reliable and steady holding of the cutting tool spindle the more high-speedily the rotary body rotates.
