Title: Supporting mechanism for running body
Inventor: SUGANO TETSUO
IPC: F16C29/04
Filed: 1985-09-14
Abstract: PURPOSE:To prevent the occurrence of oscillation with hinders the positioning control, by attaching a bearing for supply of a preloading force to a running body by an elastic attaching member whose both ends are supported. CONSTITUTION:Bearings 4-9 by which a carriage 1 is supported on guide shafts 2 and 3 are brought into contact with guide shafts 2 and 3 in the no-play state by the preloading force generated by the bearing 9. Since both ends of a flat spring 10 which generates the preloading force are fixed to the carriage 1, the rigidity in the direction other than the preloading direction of the flat spring 10 is very high, and consequently, the occurrence of unnecessary oscillation is prevented. As the result, the capacity of a servo control mechanism which positions the carriage 1 accurately is improved considerably.

Abstract: PURPOSE:To identify own line from other lines with a miniaturized small scale circuit by providing a code shift means shifting each scramble code respectively by a prescribed shift amount to set a shift amount differently for the own line from the other lines.
