Title: Hot extruding of superconducting complex billet
Inventor: II HIDEKI
IPC: H01B12/10
Filed: 1993-10-05
Abstract: PURPOSE:To extrude a high quality superconducting billet by providing a clearance of 2-10mm between the inner circumferential surface of a container sleeve and the outer peripheral surface of a stem. CONSTITUTION:A specific clearance is provided between the inner circumferential surface of a container sleeve 2 and the outer peripheral surface of a stem 4. The outer peripheral part of a complex billet 3 in which foreign matter is pushed, remains in the inner circumferential surface of the sleeve 2 as a shell 5, and a high quality extruded material 6 free from foreign matter can be provided. When the length of the clearance is less than 2mm, the amount of the shell 5 is small and foreign matter is not removed sufficiently, and when the length exceeds 10mm, foreign matter removing effect is saturated while reducing the yield of extrusion. The clearance is thus 2-10mm, and the sleeve 2 and the stem 4 are arranged coaxially, and the clearances between them are equal in the circumference. The smaller clearance stabilizes extruding pressure, and this clearance is determined considering the extruding temperature of the billet 3 and the extruded material 6.

Abstract: PURPOSE:To make a spectrum analyser easy to use, by constituting the title analyser so that a meaningless signal truck is corrected when the random movement of a signal exceeds a certain definite range and the fluctuation (dispersibility) of the signal itself can be confirmed. CONSTITUTION:When order is given to start the operation of a signal truck, the value of a count circuit 20 is reset to zero and sweep is performed under the condition set at that time and the frequency fP showing the max. level is detected during the sweep of this time by a detection means 15 to be stored in a memory means 17. Next, the difference fR=fC-fP between center frequencies fC, fP is calculated by an operation means 16. In the circuit 20, it is judged whether the frequency difference fR exceeds the first predetermined value corresponding to the sweep frequency width at that time and, when said difference fR exceeds, the value of the circuit 20 is made incremental and, when the difference fR does not exceed, the value of the circuit 20 is reset to zero. Next, when the value of the circuit 20 does not exceed the second predetermined value, it is judged whether the signal truck is continued and, if said value exceeds, signal truck operation is finished. By this method, a spectrum analyser can be made easy to use.

Title: Manufacture of ring with round profile
Inventor: FUJIWARA AKIRA
IPC: B24B19/11
Filed: 1984-12-28
Abstract: PURPOSE:To grind a material element so as to have a uniform round profile by changing secularly the advancing state of each material element from a guide groove, which is installed on a suspended shaft and meanders in the rotational direction, toward a grinder element and by changing the period of twist turning of the material element. CONSTITUTION:Guide grooves 4, 5 are formed in a main shaft 2 to bear a ring-shaped material element 1 and a pulley 6 on a tension shaft 3. A grinder element 7 rotate in the opposite direction to the main shaft 2 so that flat circular groove 8 grinds the ring-shaped material element 1 with square profile into with a round profile. The guide groove 5 meanders in the rotational direction so that the position, where the material element 1 goes apart from the guide groove 5 in the shaft 3 toward the guide groove 4 in the shaft 2, changes secularly in the axial direction of the shaft 3. If the material element 1 with square profile is rotated upon placing on the grooves 4, 5 in such a manner as to show the form of figure '8', the material element 1 going from the shaft 3 toward the one 2 is subjected to twist turning, because the angle to the axis of the groove 4 is changing secularly, and also rolls on the inclined surface of the groove 5 to produce twist turning, so that the element 1 is ground so as to have a uniform round profile.
