Abstract: A buccal tube has a base part and at least one tube, and it is formed from a metal material comprising Ti or Ti alloy, using a metal injection molding method. The buccal tube can be formed from a metal material which contains Ti as a base component, from 0.03 to 0.5 wt % C, from 0.08 to 0.8 wt % O and from 0.03 to 0.6 wt % N. The total C, O and N content in the metal material is preferably from 0.14 to 1.1 wt %. Furthermore, pores of average diameter from 0.5 to 50 .mu.m are preferably dispersed in at least a surface region of the buccal tube, and the porosity of the holes is preferably from 0.05 to 5.0 vol %. The buccal tube may further comprises at least one engaging part which is preferably formed into a hook or engaging piece for example.

Abstract: A dental-care device is constructed from a planar base and a wire receiving part positioned on the top surface of the planar base. Slots extending straight horizontally are formed at the center of the wire receiving part, and wire is passed through these slots. The device is preferably manufactured by a metal powder injection molding method, and is composed of metal material which contains Ti as the base component, C in an amount of from about 0.03-0.5 wt % by weight of the metal material, O in an amount of from about 0.08-0.8 wt % by weight of the metal material, and N in an amount of from about 0.03-0.6 wt % by weight of the metal material. A large number of pores may be scattered at least in the vicinity of the surface of the metal material. This device can be easily manufactured, has a good surface wetness characteristic, and has functional portions, such as portions of low friction and portions of superior adhesiveness.

Abstract: A hydraulic damper for an apparatus for measuring weight or force. The apparatus includes a base frame and an elastic load cell attached to the base frame, the elastic load cell having a movable part which vibrates relative to the base frame. The damper comprises pair of spaced support members fixed ot each other and to one of the base frame and movable part, a partition member fixed to the other of the base frame and movable part and positioned between the support members, a pair of flexible wall members extending between the partition member and the support members to form a pair of sealed chambers on opposite sides of the partition member, a narrow passage interconnecting the chambers, and liquid contained in the chambers whereby movement of the movable part of the load cell effects relative movement between the partition member and the support members to force liquid to flow between the chambers via the narrow passage thereby to damp the movement of the movable part of the load cell.

Abstract: The weighing apparatus according to the invention is for use on a support surface which is subject to vibration. The apparatus includes a base adapted to be positioned on the support surface and having opposing first and second sides. The base is adapted to transmit vibrations from the support surface. A tray holds the product to be weighed and has a center of gravity adjacent the first side of the base. A load cell supports the tray on the base at the first side of the base. Strain gauges connected to the load cell generate a signal indicative of the weight of the tray and any product held thereby. The signal includes oscillating noise corresponding to vibrations transmitted by the base through the load cell to the tray.

Abstract: An improved weighing device of load cell type is proposed, wherein a cantilever type load cell and a parallelogrammatic Roberval's mechanism are combined through a connecting rod having a particular shape which results in greatly increased accuracy of measurement regardless of loading position on a weighing cradle or platform of the device.

Abstract: A method and apparatus for cooling at least the inside of steel pipes. Cooling is effected while restraining the radial displacement of a pipe at a point not more than 500 mm, or preferably not more than 250 mm, away from each end of the pipe and at intermediate points spaced at intervals of 1.0 m to 2.5 m. Elliptical deformation in the cross section of larger-diameter pipes also is prevented by adding to the aforementioned cooling method and apparatus a device and step to rotate the pipe being cooled at a rate of 30 to 150 times per minute. The restraining device at one end of the pipe is designed to move in the direction of the pipe axis so that the restraint of the radial displacement at a point not more than 500 mm away from that end is at all times ensured even when the pipe length varies.

Abstract: A device for measuring components of force and moment along and about three orthogonal axes, composed generally of a central hub portion, an annular rim portion and four radial spoke portions connecting the hub and rim portions and having strain gages adhered thereon for producing electric signals indicative of strains appearing therein, and typically used in a tire tester, wind tunnel balance and the like by fixing either the hub or rim portion and applying a force to the other, the improvement of which is its relatively simple structure and exclusion of mutual interference of the respective components in measurement.
