Abrasive media formed into shapes or packs containing a compound are disclosed. The abrasive media are formed from a synthetic resin material, and contain a compound and abrasives within the formed synthetic resin material. A method of manufacturing such abrasive media is also disclosed. The method includes providing abrasives, synthetic resin and compound in their respective specific proportions, stirring them into a uniform mixture, placing the mixture into a mold, and thermosetting the same within the mold, and then removing it from the mold.

In a gyrofinishing machine, each of the gyratory shafts for holding individual works is controlled by the combination of rack and pinion and the crank mechanism for driving the rack and pinion combination so that the particular part of a work held by the corresponding gyratory shaft can be exposed for the longer time to the abrasive media used for finishing the work, and the gyratory shaft can be stopped at the particular position with high accuracy.

In the centrifugal barrel finishing machine of the type having X barrel assemblies, in which X is an integer, a method finishing workpieces whereby during a given total finishing time Y of the workpieces, each succeeding assembly containing finished workpieces is to be replaced with another assembly containing unfinished workpieces at the end of each time interval of Y/X. The workpieces in each succeeding assembly are finished X number of times each of which is for a duration of time equal to Y/X. In this way, the workpieces in each succeeding assembly can be replaced with workpieces to be finished as the finishing in the preceding unit has been completed, thereby permitting a continuous finishing process and barrel assembly replacement for each succeeding assembly without the need for exchanging the mass in all the barrel assemblies at the same time.

A workpiece handling machine having an annular barrel structure capable of vibration caused by a plurality of vibration suppliers equipped with unbalancing weights includes a sensor system which is sensitive to any difference between the reference rotational angular phase of one unbalancing weight and those of the other unbalancing weights, and a control system which is responsive to the detected signals of the sensor system for providing an analog or digital feedback control, which adjusts the phase difference to the target value. As such, not only is the synchronized phase of rotation permitted, but also the advance angle of the unbalancing weights with regard to each other can be chosen, depending upon the operational requirements such as the kind of the workpiece and abrasive media, the workpiece working conditions, the time period of the operation, and other parameters.

A vibratory plating method carried out by placing only workpieces and a plating liquid in a plating container, and applying an electric current across the plating liquid while vibrating the plating container so as to cause the workpieces to be plated as the workpieces are rolled and moved independently of one another along the plating container. By this plating method, workpieces can be plated uniformly in a very short period of time at a high current density and with a small amount of plating liquid. Moreover, it eliminates troublesome steps of manually suspending and removing workpieces from hangers.

摘要:
A ketosis-treating agent comprising, as an active ingredient, at least one amino acid selected from valine, isoleucine, serine, glutamine and glutamic acid, or a peptide or protein comprising at least one amino acid selected from valine, isoleucine, serine, glutamine and glutamic acid; a method for treating or preventing ketosis, comprising administering to a human or animal an effective amount of the above agent; and a method for treating or preventing symptoms relating to ketone bodies, comprising administering to a human or animal an effective amount of the above agent.
摘要:
Any part of an abrasive media in a solid particle or liquid form is prevented from entering a seal and/or the area where a rotary shaft bearing for a rotating barrel is sealed, thereby protecting the bearing and/or its seal against any possible damage that may be caused by abrasive media. A the barrel finishing operation performed by rotating a rotating barrel rotatably mounted inside a cylindrical stationary barrel on a lower portion thereof in a spaced relationship to the stationary barrel. The stationary barrel has an outer bottom plate at the bottom end thereof. At least one blade is mounted on the back side of a rotating plate forming the bottom end of the rotating barrel, and is rotated by rotating the rotating plate to any part of the abrasive media existing between the back side of the rotating plate and the top side of the outer bottom plate in the direction remote from the rotary shaft, thereby developing a negative pressure or vacuum area located on the back side of the rotating plate and on the side of the blade nearer to the rotary shaft. Air is then drawn from the atmosphere into the vacuum area by the action of the negative pressure, and thus an air layer is created in the vacuum area. The air layer prevents that part of the abrasive media from entering the rotary shaft bearing and/or its seal.
