Title: Production of machine structural steel suitable for cold working
Inventor: IIDA YASUTO
IPC: C22C38/00
Filed: 1995-02-07
Abstract: PURPOSE: To provide a method for producing a steel in which, in the production of a machine structural steel, spheroidizing treatment before cold working is eliminated and energy and treating time are saved owing to the elimination of the process. CONSTITUTION: A steel heated above Ac3 point is subjected to finish rolling at the temp. between Ar1 and 950 deg.C to form fine ferrite crystal grains, by which its cold workability is improved. Furthermore, in the process of cooling after the rolling, it is held at the temp. between Ar1 and (Ar1-50 deg.C) for >=10min to promote ferrite transformation, by which the ferrite area rate is increased to reduce its hardness and deformation resistance. Moreover, by the suppression of the generation of bainite, its cold workability is improved.

Title: Tau dither block trace loop
Inventor: NAMIOKA HIROTAKA
IPC: H04B1/7073
Filed: 1989-03-09
Abstract: PURPOSE:To reduce jitter of a reproduced reception code without sacrificing a response speed by switching the band width of a loop into a wide band or a narrow band width depending before and after the acquisition of the reception code. CONSTITUTION:Since a switch S is turned off at a time when a reception signal is acquired in a tau dither clock trace loop 1, the response speed of the loop in the loop 1 depends on the resistance of a resistor R1 and the capacitance of a capacitor C1. A synchronization detection circuit 12 outputs a synchronizing detection output when a PN code outputted from a PN code generator 2 is nearly completely synchronized with the reception code in the loop 1 to control the switch S to be turned on. Thus, the band width of the loop depends on the resistance of the resistor R1 and the sum of the the capacitance of the capacitor C1 and the capacitance of the capacitor C2 and the PN synchronization is kept at the band width. Thus, the response speed when the reception signal is acquired is fast and the acquisition range is widened to facilitate synchronization acquisition with the reception code.
