IPC: C21D1/18
Filed: 1999-06-28
Abstract: PROBLEM TO BE SOLVED: To provide a method for correcting the deformation in a short time with excellent accuracy while ensuring hardness even in an annular parts having the deformation in circularity too large to charge the annular parts in a correction die. SOLUTION: The hardening deformation is corrected by applying a load to at least one of the outside diameter surface and the inside diameter surface of an annular member W by a pressing jig 2 while heating the deformed annular member W after the hardening at a preset tempering temperature by an induction heating coil 3. The outside or inside diameter of the deformed annular member W is measured in at least two parts before correcting the deformation, and the deformation in the reverse direction of at least a specified correction is given to the deformed annular member W without using any correction die by pushing the major diameter side or pulling the minor diameter side of the deformed annular member W based on the result of measurement.  When the load by the pressing jig 2 is removed, the deformation of the deformed annular member W is returned to a true circle due to the elastic deformation.

Title: Signal switching system
Inventor: HORIKAWA SOJI
IPC: H04L25/02
Filed: 1988-07-21
Abstract: PURPOSE:To shorten time for searching a fault by providing protective time to the restoration of the quality of main signals only when abnormality is detected even in superimposed signals sent from intermediate repeaters and transmitting re-inputted main signals without providing the protective time to the main signals when no abnormality occurs in the superimposed signals. CONSTITUTION:Superimposing means 16, 26 and 36 which superimpose signals having frequencies different from the frequency of main signals upon sending signals and detecting means 13, 23 and 33 which separate the signals superimposed upon the main signals from inputted signals and detect presence/absence of abnormality are respectively provided to intermediate repeaters 1-3. When no abnormality is found in the superimposed signals even if abnormality is detected in the inputted main signals, the re- inputted main signals are sent to a transmission line without waiting for the lapse of protective time and, when abnormality is found in the superimposed signals also, the main signal output is transmitted after switching to a fixed pattern. Therefore, the time required for stabilizing a transmission line after the occurrence of a fault becomes shorter and, as a result, quality deterioration of monitoring information can be prevented and the retrieving time of a fault occurring section can be shortened.

Title: Gear meshing mechanism
Inventor: FUKAMACHI TATSUMI
IPC: F16H55/14
Filed: 1989-07-17
Abstract: PURPOSE:To permit the sure meshing of gears and absorb the impact in the gear meshing and prevent the breakage of the gear by an inexpensive simple mechanism by providing the impact absorbing function onto a bearing part and forming a recess for the bearing corresponding to the dimension of the gear. CONSTITUTION:Though the operation immediately before the opening of gears 3 and 3a and restoration does not become issue in particular in the state where the gears 3 and 3a are surely meshed, the impact in the gear meshing and the breakage of the gears 3 and 3a are prevented by the upward slip of a paper feeding roller 1 by the recess part of a side plate 5, when the top edge parts of the gears 3 and 3a are opposed. The opposed state of the top edges of the gears 3 and 3a permits the sure meshing of the gears 3 and 3a by the pressure of a coil spring 6 in the next drive revolution of the gear. Therefore, the gear meshing in the opening/closing part of the upper and lower mechanisms can be carried out surely free from the generation of breakage, etc., and the development of a small-sized facsimile which can be used favorably at a low cost can be assisted.
