Title: Manufacture of ti-alloy product
Inventor: UENISHI NOBORU
IPC: B22F9/10
Filed: 1986-09-30
Abstract: PURPOSE:To easily manufacture a sintered product of Ti alloy, by subjecting a Ti alloy of specific quality to crushing by a centrifugal atomizing method and then to hydrogenation, by subjecting the above powder further to crushing into an irregular shape and then to dehydrogenation, and by applying press compacting and further vacuum sintering to the above powder. CONSTITUTION:The Ti alloy containing >30% Ti is pulverized by a centrifugal atomizing method such as plasma rotating electrode method, etc. Since this powder is difficult to press-compact owing to its special shape, it is hydrogenated by heating to 600 deg.C in a hydrogen air flow to undergo embrittlement of quality. This embrittled Ti-alloy powder is recrushed by means of a ball mill, etc., to undergo reduction to powder of irregular shape, which is heated to >=400 deg.C in vacuum to undergo dehydrogenation. Successively, this powder is press-compacted and then heated to >=700 deg.C in a vacuum atmosphere of about 10<-2>Torr to undergo sintering. Moreover, if necessary, hot isostatic pressing is further applied to the above to increase the density of the sintered compact, so that sintered product of Ti alloy excellent in mechanical properties can be manufactured.

Patent JP-S6294245-A (JP)
Title: Device for returning to starting point for numerically controlled machine tool
Inventor: OTA MASAYOSHI
IPC: B23Q15/00
Filed: 1985-10-22
Abstract: PURPOSE:To enable a movable part to accurately return to its starting point without a means of detecting its position by subtracting a value corresponding to a permissible error distance one after another from an error counter, stopping subtraction at the point where the value of said error counter becomes smaller than the corresponding value, and enabling said movable part to stop without being subjected to a thrust. CONSTITUTION:A command for making a movable part travel toward its starting point through a distance more than a specified length, is issued in response to a starting point return command while, at the same time, this travel-command distance is stored in an error counter 7 and, when the movable part collides with a starting point reference body 3 and stops its traveling, a movable-part movement detecting means 6 also stops its movement and detects the stoppage of the movable part. Then, a command for subtracting a very small value, e.g., a value corresponding to a permissible error distance, one after another from the error counter 7, is issued in response to the stoppage of the movable part 4. Thus, as the subtraction proceeds and when the value that the error counter 7 stores becomes smaller than the value corresponding to the permissible error distance, it is deemed that the return to the starting point is completed, since a servomotor 5 is not generating torque. Accordingly, means of detecting the position of a movable part is not at all necessary.
